Safety precautions in daily operation of pipe bending machine

Our country's pipe bender equipment is also in the hydraulic pipe bender and automatic pipe bender and pipe cutting machine, as well as pipe shrinking machine and other pipe processing machinery, in terms of quality and technology, now has become increasingly mature and stable, not like in the past, because of the birth of a new product and new technology, we are in a state of groping, so the performance stability of the machine is relatively fragile, but today's pipe bending machine is not stable Material processing equipment is in a stable and conventional, so after the purchase of machine tools, as long as you carefully maintain the machine tools, it can be used for a long time.But in daily use, what problems often appear? There are usually problems in the hydraulic area, because when the machine is bending, the pipe is cut by a metal circular saw, and many small iron pins are left. If these iron pins are not cleaned up, they will be directly taken to the pipe bender for bending. Many pipe bender molds are bent with mandrel. For fear that the fullness is not high enough, there will be wrinkling or collapse.In this way, when the pipe bender inserts the pipe into the mandrel, these small iron pins will fall out, and the iron pins that have not been cleaned out will fall into the oil tank inside the body. We all know that the hydraulic pipe bender uses the oil pump to input the hydraulic oil, and the solenoid valve provides the hydraulic power. So most of these iron pins will be filtered out by the filter screen in our oil inlet pipe after they enter the oil tank, but a small part of iron pins will also enter the oil pump, so the iron pins sucked into the oil pump will enter the solenoid valve. Because these iron pins can't flow in the solenoid valve, the hydraulic solenoid valve will be blocked, and the hydraulic oil can't flow, so there will be a problem The corresponding action failure, resulting in the hydraulic pipe bender can not work normally.Even if there is such a phenomenon, there is no need to panic. Just press a certain action manually according to the key on the control panel, and then look at the indicator light on the solenoid valve to see which solenoid valve does not work, and then turn off the movie. Then use a 4mm Allen key to remove the solenoid valve fixed on the oil distributor. Clean the solenoid valve with clean kerosene, blow the inside with air gun, clean the iron pin inside, and then install it.

احتياطات لاستخدام بندر الأنابيب

Before operation, first check whether the smooth points of the pipe bender are short of oil, whether the motion mechanism is loose, and whether the safety protection installation is reliable, and wait to confirm that the front can be operated. Start the elbow pump, whether the system pressure can adhere to the rule range, if high, damage the hydraulic components, waste power, if too low, affect the work. Adjust the required position and angle of parts. Adjust the positioning of the parts to the required length. Adjust the vertical lifting guide rail so that the iron pipe can be clamped tightly when the guide die pressing cylinder moves. The clamping cylinder can clamp the iron pipe.In normal operation, the workpiece is put into the bending die, the front end is contacted and positioned, and the foot switch is stepped down. When operating the pipe bender, concentrate your mind and stop putting your hands or other objects into the work area. In case of emergency, press the emergency stop button, then turn the twist switch to the manual position and reset it manually. If there is any problem, report for repair in time. After the work, cut off the power supply and do a good job in cleaning and smoothing. CNC pipe bender is mainly used in electric power construction, highway and railway construction, boiler, bridge, ship, furniture, decoration and other aspects of pipeline laying and repair, with many functions, reasonable structure, simple operation, easy to move, fast device and other advantages.This machine not only has the function of bending pipe, but also can use the oil cylinder as the hydraulic jack. Compared with the numerical control bending pipe equipment, it has the characteristics of low price and easy to use, occupying the leading product position in the domestic bending pipe machine market. CNC pipe bender can stop the winding bending of pipe with one bending radius (single mode) or two bending radii (double mode) in cold state. It is widely used in the bending of various pipe fittings and wires in automobile, air conditioning and other industries. Pipe bender is mainly used for plastic forming of pipes.

How to use the die of pipe bender

There are some ways to use the die of pipe bending machine. Only by grasping its operation method can we make full use of the convenient and quick benefits brought by the die of pipe bending machine. Bending die1、 When using the pipe bender die, it should refer to the electric oil pump copy sheet.2、 When using the pipe bender die, first screw the working oil cylinder into the internal thread of the square block, so that the wheel installed on the bracket at the rear end of the oil cylinder is downward.3、 Select the die head according to the outer diameter of the bent pipe, put it on the plunger, put the groove corresponding to the two roller shafts toward the die head, and then put it into the hole of the corresponding size of the flower plate, cover the upper flower plate, insert the bent pipe into the groove, pull the flow part of the quick joint at the end of the high-pressure oil pipe backward and put it on the joint of the working oil cylinder, and screw the oil drain screw on the electric oil pump tightly elbow. When the elbow is finished, loosen the oil drain screw and the plunger will reset automatically.There are some dangerous factors in the use of pipe bender die: the flow range of bending arm is more dangerous than that of fixed arm and bending arm, the area of bending angle selector is more dangerous, and the movement space of pipe fitting loading and unloading and pipe fitting rotation in front of the head is more dangerous. From this, we come to the conclusion that the safe way to use the bending machine die is to set the emergency stop button, which will stop the power supply of all motors and servos. Avoid overloading and abusing the die of the pipe bender, and confirm the load in the operation of the machine, so as to avoid overloading the machine components, otherwise it will affect the service life of the die of the pipe bender and the safety of the operators. The biggest bending capacity is the tensile coefficient 40kg / cm2 of bendable general iron pipe.Professional pre job training and assessment can avoid or minimize the possible accidental injury in the production process. At ordinary times, we should pay attention to the safety concept of the working environment and the operation of the machine, and set important rules such as die installation guidance, safety devices and operation methods and personal safety. There is always a connector in the insulator circuit, and the connection is not allowed to touch. Only allow professional staff to open the power accessories. Before using the machine, the voltage of all transformers should be changed to suit the local supply voltage of the machine. The power supply of the pipe bender mould must be three-phase power supply and grounded according to the local power regulations. The power supply must be clearly marked.

أسباب المشاكل في ثني الأنابيب وكيفية تحسين طرق ثني الأنابيب

The processing technology of the elbow is very helpful to daily life, but there are also many problems in the use of the product. For example, there are tiny cracks on the elbow. If it is higher than the corresponding deformation temperature during the manufacturing process, the product will be deformed. Therefore, during the bending process, some cracks will appear on the outside. This is mainly related to the material of the steel pipe used for bending. In this case, under similar forming conditions with low product deformation speed and high tension, the bending Processing equipment may cause damage. Each pipe bend is completed by bending multiple times during the manufacturing process. During the manufacturing process, the pipe can be better placed on the pipe bender, so the equipment can apply the bending moment of the steel pipe to the appropriate The steel pipe layout is deformed by the ground. The elbow can be moved upward by the support of the main cylinder of the front lower mold. This will process the center elbow along the curve of the upper mold until the manufacturing is completed. In the process of processing the product, the corresponding steel pipe will be deformed. Mainly occurs in the upper mold, the upper mold acts as a placenta, and the curve of the elbow can be deformed according to other specifications and other materials.

When bending products corresponding to other pipes, the inner pipe cannot be placed on the side of the front fixture. The processing requirements must be known in advance when bending the pipe. In order to better ensure the performance of the bend, we will understand how the arc of the bend works . Next, we will discuss the arc requirements of the elbow, which can save the cost of piping equipment and molds, and conclude that the elbow space is a flat or expandable curved surface. Therefore, in the basic process of the large-diameter elbow forming process, First, the welded cross-section is a polygonal shell or a polygonal shell with closed ends, and the inside is filled with pressure medium. Due to the above reasons, the user can shorten the manufacturing cycle, greatly reduce the production cost, and does not require equipment, which is suitable for processing large-scale bends on site.
At present, the connection between the hydraulic pumps of the pipe bender no longer needs to be connected by flanges. This small improved design can not only control the waste of costs, but also find that the drive between the motor and the pump is more stable, and there is no flange connection. The noise is also greatly improved. The shaft of the axial flow pump is directly connected to the main shaft of the motor, which improves the efficiency and torsion ability of the pipe bending, thereby further improving the entire hydraulic pipeline processing machinery.

Many people who have used the pipe bender have a certain understanding of the pipe bender and hydraulic performance. In some operations of the pipe bender, a compression valve needs to be added to control the clamping device on the pipe bender. The reason for the solenoid valve is In order to reduce the user's use cost. Therefore, the external specifications that are usually purchased now can meet its product processing range. In the design of commonly used hydraulic pipe bender equipment, a more reasonable design is adopted to improve the overall performance of the pipe bender equipment, reduce costs, and take into account the application. Sex.

When the motor drives the hydraulic drive pump, the pipe bender uses the motor and the pump to connect the flange and the driver between the oil pump and the motor at the connection point of the motor and the pump. After research and improvement, we understand the cracks in the pipe bending process. The reason is to induce the protection of defects and micro-cracks in the bending process. The deformation temperature in the heated bent steel pipe exceeds a certain level, and micro-cracks will occur outside the bent pipe. In both cases, they are related to the material of the pipe bending. In order to make better use of the pipe bending machine and hydraulic pipe bending machine, the purpose of adding a compression valve to the pipe bending machine is to reduce the overload and bending of the pipe bending machine. The influence of the sliding of the stainless steel pipe on the processing quality of the bend. According to the forming conditions, the microstructure is recombined by heat treatment after bending.

الاستخدام المشترك لتقنيات تخفيف القوس في صناعة آلات ثني الأنابيب

The blowing and pushing speed is determined according to the actual pipe bending situation to match the speed of the hydraulic pipe bender. At the same time, it should be checked whether the presetting value of the mandrel is suitable and corrections should be made if this is not practical. Based on the bending and cracking of the outer arc of the pipe, the cause should be carefully analyzed. First, make sure that the pipe has a good heat treatment condition, and the weld of the steel pipe should not be in the direction of the F1 and F2 forces as much as possible, that is, do not clamp it directly by the die and die of the bending wheel; check if the crimp die pressure is too high by excluding the pipe material factor and adjust to make it fit.        For a recently used mandrel, check if its diameter is too large. If the diameter is too large, it should be ground and ensure that the mandrel and inner pipe wall are well lubricated to reduce elbow resistance and friction. between the inner wall of the pipe and the mandrel. Take appropriate measures to avoid shaking the machine, etc. In order to create wrinkles on the inside of the arc, appropriate measures must be taken depending on the position of the folds. If the front tangent point is wrinkled, the position of the mandrel should be adjusted forward so that the mandrel advances properly to provide acceptable support for the pipe. when the pipe is bent; when the back cutting point is wrinkled, the anti-wrinkle block must be installed, and the anti-wrinkle block must be installed in the correct position, and it can be attached to the platform with a pipe bending machine • The pressure of the die (wheel) must also be adjusted so that the pressure is suitable ...
