What is the complete working process of the pipe bending machine? The main features of the pipe bender are as follows: Before operating the machine, you should first check whether each lubrication point is short of oil and whether the movement mechanism is loose. After confirming that the safety protection device is reliable, The machine can be operated. Start the oil pump and check whether the system pressure is maintained within the range specified by the program to ensure the healthy and normal operation of the machine. The structure is reasonable, the function is relatively complete, the operation is simple, it can be installed quickly, and it is convenient to carry. In addition, the pipe bender also has a function similar to a hydraulic jack, and compared with the CNC pipe bender, the price has a certain advantage. If the system pressure is too high, it will damage the hydraulic components and waste power; if the pressure is too low, it will also affect the work of the machine. In the hydraulic system of the pipe bending machine, the clamping cylinder, the boosting cylinder and the bending cylinder are all locked by hydraulic control check valves, which reduces the pressure loss and ensures the reliable bending, clamping and pressing actions during the pipe bending process. Because the speed and strength of the three actions of bending, clamping and boosting are important factors that affect the quality of pipe fittings, at the same time, in order to meet different pipe bending processes, the bending cylinder, boosting cylinder and clamping cylinder all adopt oil return throttling. The speed control loop makes the system speed adjustable, the working speed is stable, no impact, and the speed load characteristic is good; the bending cylinder is equipped with a secondary throttling speed control loop, and the slow speed can be used when the bending angle is 5~10″. The bending of the pipe makes the final bending angle very close to the set bending angle, and the energy saving effect is obvious. When the pipe bender is bending, the trolley is used as a load and is pulled forward by the pipe. In order to improve the bending, avoid the wall thickness of the bending part of the pipe. Excessive thinning, reducing springback, and adding booster devices. When bending, the die not only presses the tube, but also pushes forward by the boosting force to form a side thrust to assist the bending. The bending arm of the pipe bender and The bending spindle is connected as a whole, the bending mold axis of the bending pipe can be replaced, and the clamp can move up and down. This not only has a reasonable structure, but also increases the strength of the mechanical part. It also has a simple structure, which simplifies the electrical circuit. When it is sent to the last bend, The trolley may collide with the die. At this time, the “interference zone” function can be used, that is, the die returns, the trolley continues to feed a elbow arm, and returns to a spatial corner (POB), the clamp die is clamped, the chuck is released, and the trolley exits In the interference zone, a compression mold compresses and a bending tube. In this way, the bending tube not only avoids the collision of the trolley with the compression mold, ensures the smooth completion of the last bend, but also reduces the clamping loss of the material head and reduces the production cost.
