Description

Technical Field

[0001] The utility model relates to a bending machine which is convenient for adjusting angles and belongs to the technical field of bending processing. Background Art

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate by a hinge. The base is composed of a base shell, a coil and a cover plate. The coil is placed in the recess of the base shell, and the top of the recess is covered with a cover plate. When in use, the coil is energized by a wire, and after power is turned on, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base.

[0003] The existing patent number is CN213887675U, which is a bending machine that is easy to adjust the angle. This device adopts a rotatable bending knife body design, and the angle can be adjusted directly on the machine without disassembling and replacing the bending knife body, thereby improving processing efficiency. However, this device can only adjust the bending direction for the rotation adjustment of the bending knife. It is difficult to perform different degrees of bending processing on the bent metal plate, and only obtuse angle bending processing can be performed, thereby failing to achieve one-time forming processing. The clamp used is difficult to perform continuous feeding, which affects the continuous bending processing of long plates and reduces processing efficiency. Moreover, the bending groove is set in a fixed form, which is difficult to adjust according to the required bending angle, thereby making the use of the bending machine have certain limitations and is not convenient for bending processing of various forms of bending grooves.
