Stamping die good in sealing effect

Abstract

The invention belongs to the technical field of stamping dies and particularly relates to a stamping die good in sealing effect. The stamping die comprises a first bottom plate, a second bottom plate,a lower die body, an upper die body, a first top plate, a second top plate, supporting rods and sealing units. Each sealing unit comprises a folding type air bag, a baffle, an L-shaped check block and a gas spray head. The vacuum degree of the upper die body and the lower die body in the working process is achieved through cooperation of the first bottom plate, the second bottom plate, the lowerdie body, the upper die body, the first top plate, the second top plate, the supporting rods and the sealing units, and then a movable die body is ejected out through an air cylinder at the time to complete the stamping action, so that the sealing performance and the vacuum degree between the upper die body and the lower die body in the stamping process are ensured, and the situation of blank material splashing in the stamping process is avoided; and besides, noise influences generated in the working process of the stamping die are relived, the physical healthy condition of working personnel is improved to a maximum degree, and the integral using effect of the stamping die is enhanced.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, in particular to a stamping die with good sealing effect. Background technique [0002] Stamping is to rely on presses and molds to apply external force to plates, strips, pipes and profiles, etc., to cause plastic deformation or separation, so as to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to Plastic processing (or pressure processing), collectively known as forging; stamping blanks are mainly hot-rolled and cold-rolled steel plates and strips; 60-70% of the world's steel products are plates, most of which are made by stamping Finished products; automobile body, chassis, fuel tank, radiator fins, boiler steam drum, container shell, motor, electrical iron core silicon steel sheet, etc. are all stamped; instrumentation, household appliances, bicycles, office machinery, There are also a large number of stamping parts in products such as livin...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, the sealing effect of the stamping die used in the existing production is poor, which seriously reduces the stamping effect, making it difficult for the quality of the stamped products to meet the high precision requirements of the enterprise, and in Africa In the sealed state, the stamping die produces a lot of noise during the working process, and the blank may also produce waste splashes during stamping, which seriously affects the health of the staff; the invention proposes a sealing effect good stamping die
