Sheet follow-up supporting device of bending machine

Abstract

The invention discloses a plate follow-up supporting device for a bending machine, and relates to a plate supporting device for a bending machine. The device is connected with a control system of the bending machine, arranged at the position of a lower die on a workbench of the bending machine which faces a discharge opening, and consists of at least two cylinders distributed on the lower side of the discharge opening and retainer plates hinged with the top of cylinder piston rods; the cylinders are fixedly connected to the lower part of the outer side of the discharge opening of the workbench of the bending machine; hinge seats are arranged on the bottom surfaces of the retainer plates; the tops of the cylinder piston rods are connected with the hinge seats on the bottom surfaces of the retainer plates by hinge shafts; and the movement of the cylinders is controlled by the control system according to time sequence of the bending movement. The device ensures that the plate drops quite slowly, and prevents collision between the plate and the workbench.

Description

technical field [0001] The invention relates to a sheet metal support device of a bending machine, in particular to a sheet material follow-up support device that can move synchronously with the bending deformation process of the sheet material. Background technique [0002] Sheet metal bending processing currently has a large-scale and large-scale demand. When processing large-size and large-thickness sheets, after the sheet is bent and formed, it will fall toward the center of gravity of the sheet after bending, and the sheet will collide with the supporting workbench. On the one hand, it will generate a lot of noise, and in addition, it will damage the equipment, or cause the bending angle of the finished product to lose precision due to impact. In addition, there are safety problems. When the size of the sheet is too large, the fast falling sheet may injure or cause other small workpieces to splash and injure personnel. [0003] In the past, in order to solve this prob...

Problems solved by technology

On the one hand, it will generate a lot of noise. In addition, it will damage the equipment, or cause the bending angle of the finished product to lose precision due to impact.

In addition, there are safety issues. When the size of the sheet is too large, the rapidly falling sheet may injure or cause other small workpieces to splash and injure personnel.

[0003] In the past, in order to solve this problem, it is generally used to manually connect the plates on both sides of the discharge port during processing to prevent the rapid fall of the plates. The above problems occur, which increases the labor intensity of the operators.

With the improvement of automation, CNC bending machines have entered the market, the purpose is to improve work efficiency and reduce the labor intensity of personnel, but this problem still requires manual assistance
