Problems solved by technology

Due to the high technical content, complex structure and high production cost of this multi-station stamping transfer device, some parts of this device are directly produced on the stamping equipment, so they must be tightly bound with the punching machine to complete the transfer of workpieces. Action, therefore, this device cannot be sold separately, it is sold together with the punch
The sales price of multi-station presses is much higher than that of ordinary presses with the same stamping force. The high price has become an obstacle for small enterprises to purchase equipment and use this equipment for efficient production. Renovation of equipment to realize multi-station high-efficiency production of stamped metal drawing parts
However, due to the weak multi-station stamping technology in China and the slow development of multi-station presses, many domestic small enterprises do not have the technical ability to transform presses

Abstract

The feeding method for multiple site punching of drawn hardware piece is to push the workpieces successively along the conveying track from one site to the next with one periodical push force for punching in the preset sites. The corresponding feeding mechanism may be used in different punches, including precise punches and common punches. The present invention has stable transfer and stable running.

Description

technical field [0001] The invention relates to a method for processing stretched hardware parts, in particular to a feeding method for producing stretched hardware parts with a multi-station punch. Background technique [0002] The multi-station stamping method of metal drawing parts is an advanced and efficient production method. Multi-station stamping technology has developed rapidly in industrialized countries in Europe, America and Japan, and its application scope is expanding day by day. The characteristic of this stamping method is that the workpiece is transferred from one station to another by the transfer mechanism with a manipulator (clamp) for stamping. The station that can only be completed by a production line composed of multiple presses can be stamped in a multi-station mode, and multi-process processing can be completed on one press. [0003] As shown in Figure 3, it is a schematic diagram of the existing process of using a manipulator to clamp and feed me...
