Description

Technical Field

[0001] The utility model relates to the technical field of limiting devices, in particular to an automatic limiting device for a bending machine. 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 consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base consists of a seat, a coil and a cover plate. The coil is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate.

[0003] A bending machine can bend plates or rods, and it is widely used nowadays. A small bending machine is a type of such equipment. It is portable and convenient. However, the stability of a small bending machine is relatively general when bending materials, and manual limiting is often required. However, the accuracy and safety of manual limiting are insufficient, so it is difficult to meet social needs. Therefore, a limiting device for a bending machine is proposed to solve the above problems.

[0004] In the specification of the Chinese utility model patent application CN213968427U, a limit device for a bending machine is disclosed, comprising a bottom plate, a locking bolt is movably connected to the inner side of the bottom plate, a limit adjustment platform is fixedly connected to the top of the bottom plate, an adjustment slot is provided on the top wall of the limit adjustment platform, plug rings are fixedly connected to the inner walls of the left and right sides of the limit adjustment platform, and the limit rods are plugged into the opposite sides of the two plug rings, and the outer sleeve of the limit rod is sleeved with an adjustment block, and the top of the adjustment block is fixedly connected to the mounting plate, and the top of the mounting plate is fixedly connected to the limit frame, and a transverse limit slot is provided on the inner bottom wall of the limit frame. The limit device for a bending machine has a simple overall structure and is convenient for stably limiting the material to be bent. At the same time, the material is adjusted in position when the equipment is bent, thereby effectively solving the problem of insufficient accuracy and safety of manually limiting the material on the bending machine, but not solving the problem of inconvenience in adjusting the bending spacing and control. For this reason, we propose an automatic limit device for a bending machine. Utility Model Content
