A hedge type multi-station hydraulic press

Abstract

The invention belongs to the technical field of punching machines, and specifically provides an opposite stamping type multi-station hydraulic punching machine comprising a bracket, a working table, arotary module and a stamping module; the top of the bracket is provided with the working table; the rotary module is installed on the working table; the rotary module comprises a driving motor, a mounting plate, a rotating disk and a fixed die; the stamping module is installed on a cross beam of the bracket, and slidably connected to the working table; and the stamping module comprises a No.1 opposite stamping unit and a No.2 opposite stamping unit; and the rotary module is coordinated with the stamping module for achieving multi-station stamping. According to the hydraulic punching machine,a workpiece is subjected to primary stamping through the No.1 opposite stamping unit of the stamping module; upon completion of the primary stamping, the rotating disk of the rotary module is rotatedso that the workpiece is transferred to a working station of the No.2 opposite stamping unit; at the moment, a new workpiece is installed on the fixed die on the working station of the No.1 opposite stamping unit, and the multi-process continuous stamping can be achieved through cyclic stamping; and the stamping efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of punching machines, in particular to a hedge type multi-station hydraulic punching machine. Background technique [0002] The traditional hydraulic punching machine includes a vertical upper die stamping plate and a lower die stamping plate. When working, the workpiece is placed between the upper die stamping plate and the lower die stamping plate, and the upper die stamping plate is driven downward by the driving device. When the workpiece is stamped, usually the stamping plate of the upper die or the stamping plate of the lower die is provided with a punch for forming the workpiece. Since the punch punches the workpiece in one direction, it is easy to cause insufficient stamping pressure or one side of the workpiece. Deformation affects the processing quality of the product. [0003] There are also some offset punches in the prior art. For example, a Chinese patent with application number 2014200821333 ...

AI Technical Summary

Problems solved by technology

[0004] This technical solution can stamp the workpiece from two relative directions, but this solution still has the following disadvantages: it can only be stamped for a single workpiece, and it is necessary to take out the previous workpiece after stamping to carry out follow-up work, and it cannot adapt to multi-process stamping ; At the same time, continuous stamping is easy to cause bending and wear of the stamping rod, resulting in the offset of the stamping position and affecting the stamping accuracy
