The installation of the pipe bending machine mold is an extremely important task. Mold installers need to have professional knowledge in operating pipe bending machines and correctly adjusting pipe bending molds, which is crucial for the quality of pipe bendingOften important. The mold must be suitable for the size of the machine. If the bending degree of the pipe is greater than the original value and the machine load is too large, it will cause mechanical performance failure and may harm the operators.Mold installation personnel must cultivate a sense of personal safety awareness, and mold installation must be carried out with a safe attitude. All mold installers should be aware of the importance of their own safety,And provide a safe operating environment for others while performing work.When the oil pump motor is started, do not place your hands, fingers, or any part of your body in the mold operation area.2. Do not install, adjust, or move the mold until you have read or understood the mold installation instructions in the manual.3. When working or approaching the machine, do not wear a tie, jewelry, or loose clothing.If the mold is too heavy to be lifted by hand, appropriate mechanical lifting methods should be used. Lifting rings should be installed on the mold and used during the lifting process to maintain the stability of the mold parts.Before installing the mold, it should be wiped clean and cleaned of dust, metal shavings, or other foreign matter and dirt. Otherwise, it may cause mismatch and result in personal injury or damage to the machine or moldBad.6. When different operations require changing the control settings of the pipe bending machine, please confirm whether the setting of the selector switch is correct. Before conducting bending operations, please conduct a trial run to ensure operationCorrect.7. Elbow lubricant can cause slipping around the mold and contaminate the mold area. Handle the mold carefully. When bending, insert the end of the pipe coated with absorbent paint into the safe and practical range of the mold,To prevent bending. Lubricating oil droplets on the machine.8. If the pipe bending machine malfunctions or there is no one on duty, even if the time is short, please check the settings of all switches before restarting the machine.

With the development trend of new technologies, the quality and technology of pipe bending machines in China have become quite complete and stable compared to pipeline production equipment such as hydraulic pipe bending equipment, automatic pipe bending equipment, laser pipe cutting machines, and locks. Everyone is not easy to explore. Due to the emergence of new technology applications in the past, the stability level of mechanical equipment characteristics is relatively sensitive, but now the pipeline production line equipment is basically stable, so attention should be paid to maintenance after purchasing a processing center.In this way, when the pipeline is inserted into the journal, the iron pin will come out, and the remaining iron pin will fall into the car fuel tank. As is well known, the pipe bending machine uses an oil pump to input oil and displays hydraulic pressure according to the car relay. Therefore, after this type of iron pin enters the car fuel tank, most of it will be ejected by the filter of the input oil pipe, but very few iron pins will enter the oil pump, causing the iron pin of the suction oil pump to enter the car relay. But this type of iron pin cannot flow in the car relay, causing the hydraulic relay to be blocked, the oil to not flow, resulting in the failure of the matching state, and the inability of the bending equipment to work properly.But what are the common problems that pipe bending machines often encounter in daily use? In the technical draft of system logging, I believe this issue has been mentioned for a long time. People often say that there is a problem in the area where the hydraulic press is located, because when the machine and equipment are at the elbow, fiber laser cutting the pipeline will leave a large number of small iron pins. If this type of iron pin cannot be cleaned thoroughly, the bent pipe in the pipe bending machine will immediately encounter it. But many of the long worn materials of the pipe bending machine are bent by the core shaft, which may wrinkle or collapse in the pipe bending machine.

When selecting the bending action, the automatic pipe bending machine can choose to decompose the action, observe interference points, modify the action, and improve efficiency. The control system of CNC hydraulic automatic pipe bending machine has certain requirements for specifications. The automatic bending machine now has the opportunity to change its previous shape, with high work efficiency and small errors, and is very popular in the market with high requirements for bending processing. The automatic pipe bending machine adopts a CNC system
2、 The fully automatic pipe bending machine has manual operation, automatic operation, programming pictures, and mechanical parameter setting pictures.
III (1) Touch screen display, CNC computer operation, capable of storing 500 sets of memory
(2) Bounce compensation value setting program, program, and processing data confidentiality function

(4) The operating system is equipped with passwords, keys, quantity, and time records for easy production management
(5) With slow bending and slow core pulling functions
(6) The error message is displayed on the screen to help the operator immediately clean it up
4. The guide rail and steel wire of the hydraulic pipe bending machine should be kept clean and not contaminated. The guide wheel and bearing should be rotated for several tens of seconds before starting to dispose of sewage. When installing the servo motor on the automatic CNC pipe bending machine, do not strike or collide, especially when the movement causes the wire frame and bed surface to move, as this can cause accuracy issues with the pipe bending machine.

When the temperature exceeds the value of the product in the process of processing, the surface of the product will appear degree of deformation, so that the surface of the product will appear a lot of fine cracks, in fact, such a problem is not only because of the temperature, but also may be caused by the problem of bending materials, in the process of processing products appear high-speed deformation will lead to damage to the processing equipment.


Crack formation conditions, we all know that the product in the process of processing the length of the crack can reach the vertical axis of the vertical bending machine in the grain boundary, is also said to be perpendicular to the tensile pipe clamp, after heat treatment, the product needs to be bent, the product surface of the micro crack will become a crystal pull, the general study of the mechanics of bending pipe processing equipment and micro crack situation, The tensile strength of the product is not affected at indoor temperatures.


When the pipeline is transported and processed, the bending direction of different products will also change with different radii and angles, and such products will also become an indispensable part of the engineering pipeline. If the wall thickness of the product is changed and the bending mechanical properties change, it will affect the quality of the product. The technology of the product is very important when it is processed.


In fact, processing technology is very important, in the process of processing, we have to ensure the processing temperature and bending degree of the product, because most of the cracks on the surface of the product are affected by the temperature during the processing process, the higher the temperature, the micro-cracks will gradually increase, and a small part is because of the micro-cracks on the surface of the product when it is hot bending.


The wear of CNC pipe bending machine is generally more serious, then how should we reduce this wear?


First, the imported guide rail should add new grease every week to reduce wear damage.


Second, clamp the cylinder, bearing, slide using grease, fill once every 1-2 weeks.


Third, the lubrication of the remaining parts of the bearing should be cleaned and loaded every year.


Four, automatic CNC bending machine spindle bearing, used in high-speed grease opening and closing mechanical seal without lubricating oil.

There are various types of design and manufacturing of pipe bending machine equipment, as well as various types of processed workpieces, which may have different uses, and the technical principles will naturally differ. At this point, what advantages do single pipe bending machines or automatic pipe bending machines need to have in the manufacturing process in order to be sold?
Advantage 1: High degree of automation. Whether it is the operation of a single head pipe bending machine or a fully automatic pipe bending machine, it can achieve automatic and intelligent completion of the process. This will also be of great help in improving the processing quality. After all, many manufacturers have strict requirements for precision when manufacturing and designing, in order to further improve the quality advantage of the processed objects and achieve the standard of customer satisfaction.
Advantage 2: High accuracy. Of course, the key to the machining process of a single head pipe bending machine lies in the advantage of accuracy. As long as the accuracy continues to improve, the errors in this area will be reduced, indicating that the quality advantage of processing applications will be more prominent. Only in this way can we achieve customer trust and recognition in the market sales process. Only by comparing their accuracy can we know that the technological gap between them will continue to widen.
Advantage 3: Reasonably control costs and meet customer budget standards. As more and more customers choose manufacturers to customize single bending machine equipment, customized processing or reasonable cost control can meet customer budget standards, continuously increasing order volume and providing customers with reliable choices. Therefore, this will be very popular in the process of promoting single pipe bending machines in the market.

With the development of numerical control technology, many factories will choose to use some advanced equipment, pipe bending machine before operation and use, pay attention to the relevant parameters to complete the specific adjustment. When using, pay attention to use in accordance with the correct specifications, especially if there are some failures, it is necessary to solve as soon as possible.

For the production of workpiece products that need to be bent, it usually requires high temperature heating to achieve bending processing. Specifically, when the workpiece product is heated and bent, it is usually necessary to use a pipe bender to bend the workpiece product. Only the parameters to complete the relevant adjustment, and can maintain the temperature balance, so that you can ensure the correct operation, if the use of the process, uneven heating, it will lead to the gradual increase of the pressure, will lead to pressure instability, but will directly affect the operation of the equipment.

Especially in the different environment of its own use, once the problem of uneven heating of the bending machine, it will directly affect the processing effect, so with the improvement of the current production technology, for some manufacturers, when the production of this part, pay attention to find some defects in the parts, and timely adjustment, in production technology, Also need to meet the corresponding standards, only in this way, in order to solve the problem of accessories in use.

Bends are important components widely used in various industrial fields, and are generally bent using pipe bending machine equipment. So how to conduct load tests on the pipe bending machine?




1. Each fully automatic machine should undergo a full load test and bend the pipe fittings twice (with a bending angle of 180 °) according to its maximum rotational torque.




2. During the full load test, the operation of the fully automatic pipe bending machine should be stable, reliable, and comply with relevant regulations.




When conducting type tests on 3 pipe bending machines and new or updated products, overload tests should be carried out. The overload test should be carried out three times using a fully automatic pipe bending machine, bending the pipe fittings with a high rotational torque of 110% (bending angle of 180 °). Batch standardized production is allowed to undergo sampling inspection, with a sampling rate of 10% of each batch's output, but not less than one unit.




With the development of society, the demand for various types of bent pipes in various industries will rapidly increase, and the precision requirements for pipe bending forming will also become higher and higher. This prompts people to conduct in-depth research on pipe bending processing technology and equipment.




What important roles does the pipe bending machine play in pipeline installation.




When installing pipelines, it involves site requirements and requires the use of various bends, such as 90 ° and 45 ° bends. Due to the use of a large number of bent pipes and the complexity of the on-site situation, it is not possible to make all the bent pipes in advance. The use of fully automatic equipment allows for direct on-site operation, which is very convenient.






When bending pipes, some conditions need to be met: construction drawings and standard drawings have been prepared and reviewed. When using an automatic pipe bending machine to bend, the operator's face should avoid the bent steel pipe to prevent the pipe bending machine from slipping and injuring people. When using fire to simmer and bend, it is prohibited to stand at the pipe mouth to prevent injury from blasting. The position of the coal furnace should be in contact with the fire department, and flammable materials surrounding it must be eliminated. The fire must be extinguished before work to prevent accidents.

The hydraulic pipe bending machine should be operated carefully to:


1. When starting the machine tool, be careful not to let the human body enter the range scanned by the rotating arm.


2. When the machine tool is working, all personnel are prohibited from entering the space swept by the rotating arm and pipe fittings!


3. The hydraulic system of the machine tool adopts YA-N32 ordinary hydraulic oil, which is replaced once a year under normal circumstances. The oil filter must be cleaned at the same time.

4. When adjusting the machine tool, the adjuster should press the button themselves to make the adjustment. Never allow one person to adjust on the machine tool and another person to operate on the control cabinet.


5. When adjusting the machine tool or operating the empty car, the core rod should be removed.


6. The hydraulic system pressure should not exceed 14Mpa.


7. When manually adjusting the speed of the side push oil cylinder, the rotary arm should rotate to ≥ 900 for adjustment. The adjustment speed should be synchronized with the linear speed of the rotary arm rotating the edge of the bent pipe mold. It is prohibited to push the side push at a speed greater than the linear speed of the rotating mold edge in manual mode.


8. Generally, after using the machine for a period of time, the tension of the chain should be checked to ensure consistent tension between the upper and lower chains.

Pipe bending machines are widely used in industries such as sheet metal, hardware products, steel structures, precision machinery, automotive parts, glasses, jewelry, nameplates, advertising, handicrafts, electronics, toys, packaging, etc. They can cut metal and various non-metallic sheets and pipes. Especially suitable for stainless steel plates, iron plates, aluminum materials, copper plates, pipe bending machines/stainless steel laser pipe bending machines are commonly known as metal laser pipe bending machines.
Cutting of materials such as ceramic, silicon, and diamond. The pipe bending machine uses a metal laser with a xenon lamp as the excitation source to output a high-energy density laser beam, causing local instantaneous melting and gasification of the area illuminated by the light spot on the workpiece. The CNC mechanical system is controlled by a computer to move the position of the light spot and achieve automatic cutting. A high-tech equipment that integrates laser technology, CNC technology, and precision mechanical technology.
The typical structure of a metal strain gauge for a pipe bending machine is composed of a sensitive gate, substrate, coating layer, and lead wire. In the application of sensors, the strain of the elastic body is transformed into a change in resistance value through the resistance strain effect of the sensitive gate. Based on the inherent hysteresis of the material, the strain gauge itself also exhibits hysteresis. Sealant: A large amount of sealant is used in the production process of the sensor in the pipe bending machine, mainly for fixing the circuit and sealing.
On the surface, it is generally relatively soft after curing, and the relative strength of the elastomer can be almost ignored. However, for small-scale products, consideration must be given. Small range products have relatively weak deformation zones, and the influence of sealant thickness is significantly increased.

Pipe bending machines can be roughly divided into CNC pipe bending machines, hydraulic pipe bending machines, and so on. Mainly used in power construction, public railway construction, boiler, bridge, ship, furniture, decoration and other aspects of pipeline laying and repair, it has the advantages of multiple functions, reasonable structure, and simple operation. In addition to having the function of bending pipes, this machine can also use the oil cylinder as a hydraulic jack. Compared to CNC bending equipment, it has the characteristics of being cheap and easy to use, and occupies the leading position in the domestic bending machine market.
Professional pipe nesting skills
Due to the high cutting efficiency of the pipe bending machine, the programming nesting becomes increasingly large. If not used properly, it will cause pipe waste and low cutting efficiency. Professional pipe cutting and nesting software is used to pre program drawing, nesting, and cutting segments on the planning machine, generating NC cutting steps. However, it is outdated and can be used for cutting long metal pipes with full stroke automatic pipe bending machines. Professional pipe nesting software is the fundamental and prerequisite for achieving large-scale, efficient, and high-quality cutting production of CNC pipe cutting machines.
Next, let's talk about the characteristics of hydraulic pipe bending machines.
1. The pipe bending machine adopts touch screen and CNC module, with dialogue operation and simple and easy program setting
2. The bed structure is stable and not easily deformed.
3. Each file can be set with 16 bend angles, and the memory can store 16 sets of files.
4. Equipped with slow positioning function, stable bending angle, and repeatability accuracy of ± 0.1 °
5. The error message is displayed on the screen to assist the operator in immediately troubleshooting.
6. Provide self-developed coordinate conversion bending pipe processing values, and the software can be purchased and installed on a desktop computer for editing and calculation.

As a type of sheet metal shearing equipment, the pipe bending machine has been widely used, but due to the high power of its main driving motor, the starting current of the pipe bending machine will also be higher. In order to avoid the impact of excessive starting current on the power grid, corresponding starting current limiting measures are adopted in the pipe bending machine, and the most effective way is to use a soft start system.

Pipe bending machine

The so-called soft start is actually a depressurization start, and after the pressure decreases, the starting current will also decrease. The most commonly used step-down starting methods include star angle starting, stator series resistance starting, and autotransformer starting, which replace the original starting method and protect the power grid from damage while ensuring the normal operation of the pipe bending machine. When the motor in the pipe bending machine starts, a certain amount of starting current is generated, which often has adverse effects on the power grid. So for motors with larger capacity like this, it is generally not allowed to start under load. Soft start is the most suitable option for pipe bending machines.

After installing the mold of the pipe bending machine, the pipe bender is really complete. Whether it is a hydraulic pipe bender or a CNC pipe bender, the installation of the pipe bender mold should be paid attention to.
The installation of the elbow mold is very important. Mold installation personnel must have the expertise to operate the elbow machine and adjust the elbow mold properly, and the quality of the elbow is stressed. The mold must be applied to the mechanical size, bend the pipe fittings larger than the original value, the mechanical load is too large, the mechanical properties fail, and the operator is seriously endangered.
1. In the environment of starting the oil pump motor, arrange the hand, finger or any part of the body in the mold running area.
2. Do not use the mold installation instructions on the manual without reading or understanding, but install, mediate or move the mold.
3, do not wear ties, jewelry or loose clothes when things are happening or near the machine.
4, if the mold is too heavy to lift by hand, should use the appropriate machine lifting essentials. The hanging ring is arranged on the mold to connect the stability of the mold parts during suspension.
During the operation of the automatic pipe bender, the parts of the pipe bender can be maintained under harsh environmental conditions (such as rain), improper operation and misoperation, and overload. All systems of the pipe bending machine are suitable for operation in the environment of ±40℃ and 0 ~ 100 humidity. The pipe bending machine is suitable for local use at an altitude of 0 ~ 3000m. The pipe bending machine should select a suitable workplace before working. The quality of a fully automatic pipe bending machine is very important for the quality of the products produced in the future, so how to identify the quality of the pipe bending machine?
1. Mold base hardness and mold hardness are also the key to the normal use of the equipment in the future. When the mold hardness is lower than Rockwell HRC60 mold hardness is lower than Rockwell HRC50, it will affect the clamping quality of the hose.
2. Measure the main parameters of the equipment: let the equipment be in the state of air transport, touch each mold block with your hand, and the feel should not shake, otherwise it is regarded as unqualified products.
3. Install the equipment on the mold, buckle a sample joint, and measure the buckle joint with a caliper or micrometer. The circularity and taper should be buckle within 0.1mm, which is considered excellent.
4. Check the equipartition of the eight valves of the mold base and the flatness of the mold. Good equipment will do special control adjustment for these two items, and some poor quality equipment does not control the above two parameters.
