Die with stretching male die and bottom hole punching stripping block integrally formed

Abstract

The invention discloses a die with a stretching male die and a bottom hole punching stripping block integrally formed. The die comprises: an upper die plate, wherein a die handle is welded to the center of the upper surface of the upper die plate; a first fixing plate formed on the lower surface of the upper die plate; an upper die base plate fixedly mounted below the first fixing plate; a material pushing gasket formed in the first fixing plate and located between the upper die plate and the upper die base plate; a second fixing plate fixedly welded to the bottom of the upper die base plate, wherein a punching male die is fixedly installed in the middle of the second fixing plate; a trimming female die formed below the second fixing plate, wherein a first guide column is connected between the trimming female die and the second fixing plate in a sliding mode; and the stretching male die located on the inner side of the trimming female die, wherein an inner pushing material is arranged between the stretching male die and the trimming female die. The device is of an integrated structure, it is guaranteed that the stretching die is always higher than a bottom hole punching die, the problem that in the production process, products are prone to deformation is solved, and the product percent of pass is increased.

Description

technical field [0001] The invention belongs to the technical field of integrated equipment for stretching and punching of aluminum plates, and in particular relates to a mold for integrally forming a stretching punch and a stripping block for punching bottom holes. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products, it mainly realizes the shape of the article through the change of the physical state of the formed material It is widely used in punching, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as engineering plastics, rubber, Compression molding or injection molding of ceramics and other products. [0003] During the forming process of the aluminum plate, since the aluminum plate is required to be stretched and punched at one time, t...

AI Technical Summary

Problems solved by technology

If the punching die is higher than the drawing die, it will cause punching first and then stretching, resulting in deformation of the bottom hole and affecting the product qualification rate
