Anti-stretching device for fixing plate of bending machine

Abstract

The invention discloses an anti-stretching device for fixing a plate of a bending machine, and belongs to the technical field of fixing and stretching prevention of plates of the bending machine. Theanti-stretching device is characterized in that top blocks cooperating with bending grooves are arranged at the top of a workbench, the left side and the right side of the top of the workbench are correspondingly provided with slideways, assembling cavities are formed in the bottoms of the slideways, clamping plates are nested in the assembling cavities, the top ends of the clamping plates penetrate through the slideways and extend to the parts above the workbench, inner rods of electric telescopic rods extend to the bottoms, connected with the clamping plates, of the side walls of the assembling cavities, compression springs are connected to the bottoms of the side walls of one sides, far away from the electric telescopic rods, of the clamping plates, the other ends of the compression springs are fixed on one sides, far away from openings, of the assembling cavities, and supporting springs are connected to the side walls of one sides, far away from the top blocks, of the clamping plates. And therefore, the thin plate can be positioned longitudinally and transversely, then the phenomenon of stretching of the thin plate is effectively prevented, and the situations that the quality of the thin plate is influenced due to the fact that the stretching phenomenon occurs after the thin plate is bent are avoided.

Description

technical field [0001] The invention relates to the technical field of fixing and anti-stretch bending machine plate parts, in particular to an anti-stretch device for fixing bending machine plate parts. Background technique [0002] A bending machine is a machine that can bend thin plates. During its working process, it often needs fixing devices to fix it so that the bending machine can work better. However, for the bending machine fixing devices currently on the market It is said that there are still a large number of problems, such as the fixing device cannot resist stretching when the bending machine processes the thin plate, and the bending is realized after the workpiece is fixed and clamped, resulting in the problem of poor quality of the thin plate after bending , that is, there will be excessive stretching at the bend, which will seriously affect the processing quality of the bent parts, which greatly affects the development of the bending machine. Therefore, we pr...

Therefore, we propose an anti- stretching device
