Description

TECHNICAL FIELD

[0001] The application relates to the technical field of stainless steel processing, in particular to a positioning structure for a stainless steel bending machine. BACKGROUND

[0002] The hydraulic bending machine is a device capable of bending a sheet, and mainly comprises a support, a workbench and a clamping plate. The workbench is arranged on the support, and the workbench is composed of a base and a pressing plate. The base is connected with the clamping plate through a hinge.

[0003] When in use, the hydraulic cylinder pushes the upper die to move downwards to bend the stainless steel plate placed on the lower die. However, due to the physical properties of the bent stainless steel plate, when the upper die moves away, the bent stainless steel plate is prone to slight rebound in the lower die, which leads to a larger bending angle and deviation from the preset bending angle, increases the processing error and reduces the bending effect.

[0004] Therefore, the technical personnel in the art provide a positioning structure for a stainless steel bending machine to solve the problems in the background art. CONTENT OF THE UTILITY MODEL

[0011] Preferably, the upper die is distributed directly above the lower die forming groove.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] By driving the motor to rotate the lead screw, the second support plate cooperates with the first support plate to drive the first support rod and the second support rod to move downward synchronously, thereby making the two side pressing plates move downward synchronously, timely pressing and limiting the two sides of the bent stainless steel plate in a short time, positioning and shaping, avoiding the rebound of the bent stainless steel plate in the lower die forming groove after the upper die moves away, causing the bending angle error to increase, and improving the effect of the equipment during processing.
