Description

Protection device for bending machine Technical Field The utility model relates to the field of bending machines, in particular to a protective device for a bending machine. Background The bending machine is also called a bending machine, is mechanical equipment for bending metal plates, drives a die to move relatively through a hydraulic system or a mechanical transmission system, realizes bending forming of the plates, has various types including manual, hydraulic, numerical control and the like, has various characteristics, and is suitable for processing requirements of different scales and precision. The traditional plate folding machine needs to manually place the plate which is not bent on the plate folding machine in the using process, then the plate is limited and pressed, and meanwhile the plate is bent by matching with a plate folding mechanism, but the plate folding machine has a problem in the actual using process, in particular to the operation of placing the plate between the clamping part and the operating platform, and an operator places hands in a gap between the plate and the clamping part, so that certain potential safety hazards exist. Disclosure of utility model Accordingly, the present utility model is directed to a protection device for a bending machine, which solves the technical problem that an operator is at risk of misplacing a hand in a gap between a plate and a clamping portion when placing the plate between the clamping portion and an operation table. The protection device for the bending machine comprises a supporting table top and a workpiece, wherein a pressing plate is arranged above the supporting table top, a protection mechanism is arranged below the pressing plate, the protection mechanism comprises two groups of guide frames, one side of each guide frame is fixedly provided with a mounting plate, the mounting plate is movably connected with the pressing plate, and the two groups of guide frames are in mirror symmetry structures and are used for limiting the workpiece.
