Working principle of CNC pipe bending machine

CNC pipe bending machine is used to produce multi-curved space, high appearance size requirements, relatively curved radius of hollow pipe fittings, especially the exhaust pipe on the car, the oil pipe on the engine.Pipe bending machine refers to the machine used for bending can also be done jack, roughly divided into CNC bending machine, CNC bending machine, etc., used in electric power construction, railway construction, bridge, ships and other aspects of pipeline laying and repair. Operating principle of CNC pipe bending machine: The high pressure oil output by the electric oil pump is sent into the working cylinder through the high pressure oil pipe, which pushes the plunger in the working cylinder to generate thrust and bend the pipe through the bending parts.Especially the exhaust pipe on the car, the oil pipe on the engine.The CNC pipe bending machine mainly consists of four parts: bending rotary shaft device, y and b shaft combination mechanism, adjustment device and cordurol feeding device.Realize the space control of transportation, flipping and bending three axes, and complete the hollow tube processing with complex space shape. The bending rotation device rotates around the center of rotation o. Its angular displacement, angular speed and rotational torque m are the main control objects; the clamp mouth presses the fittings into the bending mold on the rotating table and rotates together with the bending rotating table; the rotation speed, angle and torque control of the bending shaft is realized by the servo motor of the worm on the bending shaft.
