AI Technical Summary

Technical Problem

Existing technologies for processing fragile mesh skeleton waste suffer from problems such as frictional resistance leading to arching, stacking, or breakage. Furthermore, roller drive methods are prone to stress concentration and deviation, affecting production efficiency and safety.

Method used

It adopts a cyclic clamping array combined with regional mechanical drive, and achieves low-stress surface contact conveying through clamps on an endless flexible carrier. The pure mechanical structure of clamp seat, slide bar, follower roller and drive rail eliminates electrical components and cables. The stability of the feeding baseline is ensured by using scissor linkage components and asymmetric stiffness design.

Benefits of technology

It effectively avoids material stretching deformation or breakage, reduces manufacturing costs and maintenance difficulty, ensures the stability and safety of feeding, and improves production efficiency.

Abstract

This invention discloses a punching guide and positioning fixture for a punch press, relating to the technical field of punch press material guiding structures. It includes a punch press body and a frame extending along the strip feeding path, spanning from the feed side to the discharge side of the punching area. Adjustable support frames are respectively provided on both sides of the top of the frame. A clamping and conveying assembly is symmetrically mounted on the frame, used to clamp the two edges of the strip width and drive the strip to be conveyed in a straight line. This invention transforms the traditional line-contact high-pressure conveying of rollers into multi-point distributed surface-contact straight clamping by setting a clamping array that moves with an endless flexible carrier. Within the straight conveying area, several clamping clamps close simultaneously, sharing the traction force, greatly reducing the clamping pressure per unit area. It is particularly suitable for mesh-like scrap skeletons whose strength is reduced after punching, effectively avoiding material tensile deformation or fracture caused by localized stress concentration.
