Today, with the gradual development of science and technology in China, pipe bending machine tools and equipment are also becoming more and more mature and stable in terms of quality and technology for pipe processing machinery such as hydraulic pipe bending machine and automatic pipe bending machine. Now, the development of pipe processing industry and automation industry is getting closer and closer. In this era of automation and numerical control, if you can't catch up with the pace, it means to be eliminated, Therefore, the development of hydraulic pipe bender has reached a stable and prosperous period. We have focused on the future pipe processing industry automation market. The core software of the pipe bender in the future will be the era of CNC. We will gradually retreat from the NC control system with the progress and development of science and technology.

Intelligent manufacturing equipment industry mainly includes intelligent measurement and control instruments, CNC machine tools, industrial robots, new sensors, 3D printing technology, automatic complete production lines, etc. The Ministry of industry and information technology requires to focus on promoting four categories of products such as intelligent instrument equipment and intelligent equipment. Among them, intelligent special equipment mainly includes various special equipment such as large-scale intelligent engineering machinery, high-efficiency agricultural machinery, intelligent printing machinery, automatic textile machinery, environmental protection machinery, coal machinery and metallurgical machinery, so as to realize the automation and intellectualization of various manufacturing processes.With the rapid development of information technology and advanced manufacturing technology, automation and intelligent manufacturing equipment are advancing steadily. 

In 2010, the sales revenue of some intelligent manufacturing equipment industries such as industrial automation control systems and instruments, pipe benders, CNC pipe benders, metal circular saws, pipe shrinking machines and CNC machine tools exceeded 300 billion yuan. However, there are still some problems in China's intelligent manufacturing equipment industry: the ability of technological innovation is weak, and the core technologies such as new sensing and advanced control are still unable to acquire assets; The automation industry has a small scale and weak foundation. 

The market share of high-grade and special sensors, intelligent instruments, automatic control systems, high-grade CNC systems and robots is less than 5%.Hydraulic pipe bender pays equal attention to both supply side structural reform and demand side reform With the increasing policy support for intelligent equipment manufacturing industry in China, the market scale is likely to reach trillion in the future. In the next few years, the average annual growth rate of intelligent equipment manufacturing industry is expected to exceed 20%. We expect that the scale of intelligent equipment manufacturing industry will reach trillion yuan by 2015, and will exceed several trillion yuan by 2022, and the market share of domestic equipment will exceed 80%.

Hydraulic cylinders are commonly used for bending, straightening, extrusion, shearing, punching, automobile, aerospace, rail transit, automobile, motorcycle, bicycle, stroller, steel furniture, leisure and tourism products, air conditioning industry, shipbuilding, sanitary equipment, pipe making, iron processing and other industries. They are various operations such as cutting, expanding, bending and riveting of various pipes and profiles. The damage mode of hydraulic cylinder is usually in the form of strain, electric scratch, fatigue wear and so on. The existence of damage will affect the tightness of the hydraulic cylinder, which is usually manifested as oil leakage. If it is not repaired in time, it will affect the working efficiency of the hydraulic cylinder. In serious cases, it will not work, and even lead to production accidents. The following is how to disassemble the hydraulic cylinder correctly:

(1) In order to prevent bending or deformation of slender parts such as piston rod, skid support shall be used for balance during placement. When disassembling the hydraulic cylinder, prevent damaging the top thread of the piston rod, the oil port thread, the surface of the piston rod, the inner wall of the cylinder liner, etc.

(2) Disassemble the hydraulic cylinder in sequence. Due to the different structures and sizes of various hydraulic cylinders, the disassembly sequence is also slightly different. Generally, the oil in the two cavities of the oil cylinder shall be drained, and then the cylinder head, piston and piston rod shall be removed. When removing the cylinder head of the hydraulic cylinder, special tools shall be used for the snap key or snap ring connected by internal snap key, and flat shovel is prohibited; For the flange end cover, it is not allowed to hammer or pry it out with screws. When it is difficult to extract the piston and piston rod, it is not allowed to force it out. The reason should be found out before disassembly.

(3) Before and after disassembling the hydraulic cylinder, try to create conditions to prevent the parts of the hydraulic cylinder from being polluted by the surrounding dust and impurities. For example, disassembly should be carried out in a clean environment as far as possible; After disassembly, all parts shall be covered with plastic cloth instead of cotton cloth or other working cloth.

(4) Carefully check the hydraulic cylinder after disassembly to determine which parts can continue to be used, which parts can be repaired and reused, and which parts can be replaced.

(5) Carefully clean all parts before assembling the hydraulic cylinder.

(6) When the hydraulic cylinder is installed on the main engine, a sealing ring shall be added between the inlet and outlet joints and fastened to prevent oil leakage.

(7) After the hydraulic cylinder is assembled as required, several reciprocating movements shall be carried out under low pressure to eliminate the gas in the cylinder.

1. The evenly distributed machining allowance of the pipe bending machine die ensures stable and high productivity and safe bending process. When the angle is constant, the bending speed and feed rate can also be stably maintained at a high level. In this way, the change of die function and working load on the pipe bending machine is small, so there is less heat and fatigue, and then the die life of the pipe bending machine is improved.

 2. One of the most important principles of the pipe bending machine die in the bending process is to create evenly distributed machining allowance for each bending in each bending process. That is to say, it is necessary to use bending dies with different angles. At any time, the primary pipe bending machine die should be as close to the final shape of the die as possible in each process.

z3. In order to obtain the longest service life of the pipe bending machine die, continuous cutting should be carried out for as long as possible in the bending process. If the number of dies entering the bending machine and exiting the bending machine is too short, it will be obvious. This will aggravate the thermal stress and thermal fatigue on the cutting edge. A uniform and high temperature in the cutting area is more favorable to the die of modern cemented carbide pipe bending machine than a large shake.

pipe bending machine is a general term for a class of machines, which can be divided in more detail. Generally speaking, pipe bending machine is still widely used in industrial construction, and it is also an important machine, so we must understand its use. It is a great taboo to learn that you can't have a half understanding and half faith. First of all, we should be clear that as a pipe bending machine, generally speaking, it can be divided into hydraulic pipe bending machine and CNC pipe bending machine. Each has its own characteristics and its own scope of use. For everyone, we need to be serious and can't confuse these types. Today, Taiwan and mechanical experts will tell you how to solve the problems of slow working speed and oil removal of pipe bending machine.

1. How to speed up the pipe bending machine:

Generally, the pipe bending speed of the pipe bending machine has the speed grade. When the pipe is small, the fastest gear is used, and when the pipe is large, the slow gear is used. Like the above speed regulation method, it can be modified according to the prompt on the control panel. If you want to solve the problem, I suggest you buy a full-automatic CNC pipe bending machine, which can process about 1000 pipes a day.2. How to adjust the descending speed of the hydraulic bending machine?The bending machine is 

2. For the 5m double cylinder, the falling point of the cutter is different. 

The oil cylinder is newly repaired and does not fall. What should we do? Note: the domestic pipe bending machine works with high intensity and its service life will be very short. I suggest you look at the imported one.There are two travel switches beside the machine, one is height limiting and the other is pressure relief. If you adjust the pressure relief down a little, it will slow down,

3. Hydraulic pipe bending machine has slow oil inlet speed and fast oil outlet speed.

 What's the matter?Generally, when the weather is cold, the oil inlet speed will be relatively slow, because the oil viscosity is high, so it is slow. It will take an hour. It's best not to adjust the speed of the next and work inlet randomly, which is easy to be disordered. If you want to ask why the oil in the oil tank is slow when entering and fast when leaving, the pipe bending machine doesn't know. When working under pressure, the oil in the cylinder is sucked into the cylinder through the large hydraulic control valve. When working, it is pressurized by the valve body. On the return trip, the oil is returned by the valve body. Here, the oil comes back from the valve group like flushing. The large hydraulic control valve is not together with the valve group, but two large ones are hung there on the front side of the oil tank, so you can only see the surf of oil return. You can't see the oil absorption. The caliber of oil absorption is large. Don't touch it at the front. You can't hold your hand.

Note: generally, the oil return is faster than the oil inlet

The pipe bending machine adopts tungsten steel circular saw blade for cutting. The rotating speed of the machine saw blade is 3200 revolutions per minute. The cut aluminum section is smooth without burrs, and the section does not need to be processed again. The safety performance of the machine is good. Pedal the pneumatic switch, and the saw blade cuts from bottom to top, which is safe and reliable. It is especially suitable for cutting and blanking with required precision such as copper aluminum heat sink. Before pipe bending machine, adjust the cutting tool and clamp the work object. The parking baffle shall be fixed, and the work can be carried out only after the test run in the sequence of clamping, loosening, forward and backward. Which projects do the pipe bending machine need regular maintenance?

1. The optical path lens outside the pipe cutter refers to all lenses outside the laser and inside the pipe cutter, including reflective lens, circularly polarized lens, anti reflective lens and focusing lens. Except for the focusing lens, which is required to be scrubbed once a day, other lenses should be scrubbed once a month to keep the lens clean.

2. The replacement cycle of cooling water in the water cooler is generally 3 months. Check the water volume in the water tank once a month in summer to avoid water shortage in the water tank caused by dry and hot evaporation in the weather, and replenish water in time. When using water cooler in freezing environment in winter, antifreeze should be added to the cooling water.

3. The moving parts of the machine tool of the pipe cutter are precision moving parts, and the long-term reliable lubrication state shall be ensured. Most pipe bending machines use automatic lubrication for regular grease filling. If manual grease filling is adopted, it should be filled once a week.

The development of hydraulic pipe bending machine in China is relatively late, and it is in the initial application stage at present. Moreover, due to the technical level of users and the limitations of various environmental factors, the needs of China's hydraulic pipe bending machinery are like a "pyramid". The demand for high, precision and sophisticated equipment is the spire; The demand for medium and low-grade equipment is like the bottom of the "pyramid", with large quantity, wide range and unlimited business opportunities. With the increasing market demand, China's automatic hydraulic pipe bending machine has developed rapidly after the 1990s.

The application scope of hydraulic pipe bending machine is very wide, which can be applied to different fields in different industries. Of course, the guarantee equipment used in different industries is different, but the function is the same. The development of modern enterprises, no matter what industry, is inseparable from the addition of hydraulic pipe bending machinery. Hydraulic pipe bending machine has become the general talent of major production enterprises.

The hydraulic pipe bending machine makes the goods wear a beautiful coat, stimulates the purchase desire of the majority of consumers, and thus improves the sales volume of the goods. The hydraulic pipe bending machine has been highly praised by consumers since its listing, and the market demand for hydraulic pipe bending machine is also on the rise. Hydraulic pipe bending machine plays an important role in enterprise production. After the addition of hydraulic pipe bending machine, the enterprise has developed more rapidly and rapidly.

Driven by science and technology, the hydraulic pipe bending machine has been developing upward, and now it has reached a certain level. It has become a potential hydraulic pipe bending machine in the machinery market and a powerful helper in various enterprises. The manufacturer of hydraulic pipe bending machine also said that under any circumstances, the hydraulic pipe bending machine takes good performance and function and reliable mechanical quality as the development goal, takes market demand and requirements as the development guidance, and combines excellent technology with its own ideas to create a high-quality hydraulic pipe bending machine with more benefits for the enterprise. Of course, this is not an easy thing to accomplish, but as long as you have determination, confidence will be able to go strong, to success and to the world.

When it comes to pipe bending machines, you may feel very strange. However, we often see some bends in our days, and these bends can be said to be a product of the pipe bending machine.
pipe bending machines can be roughly divided into CNC pipe bending machines, hydraulic pipe bending machines and so on. It is mainly used for power construction, highway and railway construction, pipeline laying and repair of boilers, bridges, ships, furniture, decoration and other aspects. It has the advantages of multiple functions, reasonable structure and simple operation.
There are many kinds of pipe bending machines, which can be divided into pressure bending type, roll bending type, surrounding type and kneading type according to the form of twists and turns; According to whether it is heated during twists and turns, it can be divided into carrying bending type and hot bending type; According to different transmission modes, it can be divided into mechanical transmission and hydraulic transmission.
There is a certain danger when using the pipe bending machine, so I remind you to pay attention to safety. Today I'll share with you the problems you need to pay attention to when operating the pipe bending machine.
When starting the machine tool, pay attention that the human body shall not enter the range swept by the rotating arm. When the machine tool is working, all personnel are prohibited from entering the space swept by the rotating arm and pipe fittings. The hydraulic system of the machine tool adopts ya-n32 general hydraulic oil, which is replaced once a year under normal circumstances. It is necessary to clean the oil filter at the same time. When adjusting the mold, the adjuster should press the button to adjust. Never adjust on the machine tool by one person and operate on the control cabinet by another person. Remove the core rod when adjusting the machine tool or driving empty. The hydraulic system also needs to pay attention to the pressure in operation.
In addition, the pushing speed of side pushing under manual condition shall not be greater than the linear speed of rotating die edge. Generally, after the machine is used for a period of time, check the tightness of the chain and adhere to the joint tightness of the upper and lower chains. During automatic operation, in the zigzag mode with core, before the bending arm comes back, it is necessary for the operator to ensure that the core head is in the pipe or that the mandrel is not blocked when the bending arm comes back, so as to avoid bending or breaking of the core head or core rod.

The advanced pipe bending machine adopts a large number of new detection systems to ensure the processing progress and stable and reliable operation of the pipe bending machine. With the increasing penetration of automation manufacturers into the industry and the development of information technology, more and more designers accept advanced automation technology and use advanced automation products to improve the performance of equipment. The overall level of the pipe bending machine in China lags behind that in developed countries for many years. In addition to the improvement of the technical level of domestic manufacturers, the localized production of foreign manufacturers has also greatly promoted the improvement of the automation level of China's pipe bending machine products. The internationalization of the trend is the goal that the bending process has always pursued, but it is not enough to just shout slogans. If you want to really step on the international stage and move forward with the high-end, you must comply with the development trend of the times and integrate modern technology into mechanical production, so as to complete the efficient and intelligent equipment.
With the transformation of China's role as a manufacturing factory in the world, a large number of commodities produced in China every year need the market-oriented demand of pipe bending processing technology, especially the commodities produced in China to meet the international market demand need the international level, so the market of pipe bending machine in China will grow rapidly. With the continuous development of electric vehicles, automobiles and other fields, the market prospect of CNC pipe bending machine is inestimable.
After 20 to 30 years of development, China's full-automatic pipe bending machine and pipe processing machinery industry, pipe bending machine, metal circular saw and other industries have been developing continuously. Although China has become the second largest packaging country in the world, there are still many deficiencies compared with other countries. At present, China is constantly exploring the international market, and the technology is still weak.

Pipe bending machine is a kind of mechanical equipment with reasonable structure, convenient operation and various functions. Compared with CNC bending equipment, the price is cheap, easy to use, in the current domestic bending equipment market occupies a dominant position. Is a kind of efficient processing machinery equipment. Therefore, in order to the safety of the operator and the smooth progress of the work, the use of pipe bending machine needs to pay attention to the relevant matters.

When the pipe bender is working, it should be noted that all operators are not allowed to enter the space scope of the boom rotation and pipe fitting scanning, so as to avoid unnecessary safety accidents. Hydraulic system selection of hydraulic oil is specific, the general operator needs to replace the hydraulic oil once a year, at the same time cleaning the oil filter.

If the mold needs to be adjusted when the pipe bender is working, only one operator can operate at the same time, avoiding the operation of two people, that is, if the adjutor presses the button and operates by himself, do not let others control the operating cabinet or machine tool, which is prone to danger.When the pipe bender is working, the pressure of the hydraulic system shall not exceed the specified value. 

When adjusting the machine tool or empty car, the core rod should be unloaded. If it is in manual operation, the pushing speed shall not be greater than the linear speed of the rotating die edge, otherwise it will have an adverse effect on the mechanical equipment. The user should check the tightening degree of the chain regularly when using, and the upper and lower chain should be tightened consistently.

Our company specializes in the production of pipe bending machine, pipe cutting machine, CNC pipe bending machine, automatic pipe cutting machine, hydraulic pipe bending machine, sheet metal processing.

The CNC pipe bending machine is the bending production equipment at the core of aerospace engineering, vehicles, electric locomotives, motorcycles, ships, electric engineering, natural gas, sporting goods, etc. It has the characteristics of multiple functions, reasonable structure, convenient use, convenient movement, and rapid assembly. CNC pipe bender is a kind of winding bending machine equipment that can perform one bending radius or two bending radii for pipe fittings in hot state.

The remaining amount of finish machining of CNC pipe bender is an important data information. The remaining amount of machining refers to the unnecessary metal thickness of the surface layer to be produced and processed on the product workpiece in the process of machining and manufacturing. The unnecessary metal material can be removed by machining and manufacturing to obtain the surface layer of the design points.

The remaining quantity of finishing machining of CNC pipe bender also needs to be determined by comparison and calculation. Generally, customers must master various elements of the remaining quantity of harmful machining, and then determine it by combining comprehensive analysis and calculation. The remaining quantity of machining obtained by such comprehensive and clear method will be more appropriate.

The remaining amount of finish machining will directly affect the machining conclusion of CNC pipe bending machine. If the remaining amount of machining is too large, the cutting speed will need to be increased, so the dimensional accuracy and the quality of the material surface will be affected. If the remaining amount of finishing is too small, then the deviation left by the product workpiece in the previous process flow cannot be completely removed, and there are also many problems such as defects left on the surface, so that the product workpiece becomes waste. Therefore, it is very important to rationalize the remaining amount of finishing of CNC pipe bender.The company specializes in the production of pipe benders, pipe cutters, CNC pipe benders, automatic pipe cutters, hydraulic pipe benders, and sheet metal processing.
