Description

Technical Field

[0001] The present application relates to the technical field of pipe processing, and in particular to a pipe bending machine for pipe processing. Background Art

[0002] Bending machines can generally be divided into numerical control bending machines, hydraulic bending machines, etc. They have the advantages of multiple functions, reasonable structure, simple operation, etc. Compared with numerical control pipe bending equipment, they are cheap and easy to use, occupying the dominant product position in the domestic bending machine market.

[0003] A Chinese patent with the publication number CN219683664U discloses a pipe bending machine for pipe processing, including a base and a workbench arranged on the top of the base. A mounting box is fixedly connected to the top of the workbench. A rotation adjustment mechanism extending to its top is arranged inside the mounting box. A fixing mechanism is arranged on the top of the workbench. The rotation adjustment mechanism includes an adjustment lead screw rotatably connected inside the mounting box. A threaded sleeve is threadedly connected to the outside of the adjustment lead screw. The top of the threaded sleeve is fixedly connected with a connection block extending to the top of the mounting box. A mounting seat is fixedly connected to the side of the connection block away from the threaded sleeve. A servo motor is arranged on the top of the mounting seat. For this pipe bending machine for pipe processing, by rotating the rotating handle to drive the rotation of the adjustment lead screw, the threaded sleeve and the connection block are displaced, so as to be able to clamp and fix according to the length of the pipe. Then, by setting the servo motor to drive the rotation plate to rotate, the pipe can be bent.
