Strip-steel-plate continuous punching machine

Abstract

The invention relates to the field of stamping technology and aims to provide a strip-steel-plate continuous punching machine capable of preventing workpiece abrasion. The technical scheme is that thestrip-steel-plate continuous punching machine includes a frame, a conveying device and a stamping device, wherein the conveying device comprises active conveying rollers and jacking rollers; two synchronously-rotating active conveying rollers are arranged between each left side plate and each right side plate of the front and rear ends of the frame; each active conveying roller has the same height; the bottoms of active conveying rollers are higher than the upper surface of a workbench; two jacking rollers are correspondingly arranged under the foremost and backmost active conveying rollers;and strip steel plates are located between the active conveying rollers and the jacking rollers. The conveying and stamping of workpieces are carried out at different height positions, the sliding contact between the workpieces and the workbench and concave dies is avoided, and the workpiece abrasion can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a continuous punching machine. Background technique [0002] The punching machine is a kind of processing equipment widely used in the strip plate processing process. It can form various specifications and sizes of connection holes, installation holes, heat dissipation holes, weight reduction holes, etc. on the strip plate by punching. Make way holes, etc., greatly improve the automation level of strip plate processing and reduce the labor intensity of staff. However, there are still certain defects in its use. [0003] 1. When the existing punching machine is working, the strip workpiece gradually passes through the station directly below the punch under the action of the feeding device, and the punch is pressed down under the driving action of the hydraulic system and the pneumatic system to meet the work station. The die together punches the workpiece. However, during the ...

AI Technical Summary

Problems solved by technology

However, for workpieces with large plate thickness, due to the excessive pressure between the punch and the mounting seat, if the stress at the joint cannot be released evenly, it is easy to cause damage to the punch or deformation of the mounting seat

[0005] 3. In the process of punching, more waste will be produced. With the continuous production, the amount of waste is increasing. The current method is mainly to be cleaned by the staff on a regular basis, which undoubtedly increases the workload. The labor intensity of personnel also increases the probability of potential safety hazards
