Secondary stamping die for composite spacer stamping material structure

Abstract

The invention discloses a secondary stamping die for a composite spacer stamping material structure. The secondary stamping die comprises an upper template and a lower template, a composite spacer material is arranged between the upper template and the lower template, the upper template is connected with a nondestructive plunger chip, and the lower template is connected with the coordination moldcavity of the nondestructive plunger chip. A nondestructive elastic cushion on the stamping die has very good tenacity, so as to ensure that a stamped spacer cannot be deformed, and convex and concavegrooves on the surface of the spacer are protected from being damaged; the stamping die can be used for protecting the convex and concave grooves on two sides of the stamped spacer from being damagedvery well.

Description

technical field [0001] The invention relates to a stamping die, in particular to a secondary stamping die of a composite pad stamping material structure. Background technique [0002] Gaskets play an important role in various components. When we need to fasten two connecting parts, we often put a gasket under the nut so that the gasket can rely on friction when the nut is tightened. To achieve the effect of anti-loosening. However, such gaskets are inelastic, and after they are fastened with the screws or nuts, the screws or nuts will be backed up after violent vibrations, so that they may become loose or even fall off. Therefore, the existing gasket also has potential safety hazards. As the precision of electronic components is constantly improving, people's requirements for gaskets are also gradually increasing. The current gaskets have poor rigidity and cannot withstand high temperatures, and traditional gaskets are single-layered, without good elasticity, easy to defo...

AI Technical Summary

Problems solved by technology

The current gaskets have poor rigidity and cannot withstand high temperatures, and the traditional gaskets are single-layered, have no good elasticity, are easy to deform, and cannot achieve the dual effects of anti-loosening and tightening, and cannot meet the needs of large-scale machinery and equipment. Required requirements in special working environments

The current gaskets are processed by machine stamping. This processing method has a high scrap rate, low production efficiency, and the processed gaskets are prone to deformation. Impact deformation of concave and convex grooves on the material
