Material withdrawing mechanism of inclined wedge stamping die

By introducing a transversely moving wedge block and a longitudinal drive block to drive the punch in the wedge stamping die, combined with an elastic ejection mechanism and a lubrication hole sealing structure, the problems of insufficient pressing and ejection space and inconvenient lubrication in the side punching of the wedge stamping die are solved, and an efficient and automatically lubricated ejection process is realized.

AI Technical Summary

Technical Problem

Existing wedge stamping dies have insufficient space for the blanking and ejection devices when punching holes on the side, and the ejection process is complicated and inconvenient to lubricate, which affects the smoothness of ejection.

Method used

A material ejection mechanism for a wedge stamping die was designed. The wedge block with lateral movement drives the punch to punch holes. Combined with the longitudinal movement of the drive block, the wedge block drives the lateral movement. The clamping plate clamps the material and achieves automatic lubrication and smooth ejection through the elastic ejection mechanism on the fixed block. The lubrication effect is ensured by the lubrication oil hole and the sealing structure.

Benefits of technology

This allows for simultaneous clamping and unloading of the material, reducing the frequency of lubricant addition, improving the smoothness of unloading and lubrication, and preventing lubricant leakage.

Abstract

The utility model relates to punch die technical field especially relates to a kind of material withdrawal mechanism of inclined wedge punch die, punch is driven to carry out punching operation by setting transverse motion's inclined wedge block, and inclined wedge block is driven transverse movement by longitudinal moving drive block;By setting clamping plate to the part is pressed and clamped, so that material pressing and clamping and material withdrawal are realized simultaneously, punch is set sliding elastic material withdrawal mechanism by fixed block to carry out material withdrawal after punching is finished, and fixed block is lubricated elastic material withdrawal mechanism by lubricating oil hole and adds lubricating oil, so that lubrication effect is good, and elastic material withdrawal mechanism moves process can contact lubricating oil and realize lubrication, without frequently adding lubricating oil.
