Explosion proof aluminous shell stamping forming die of capacitor

Abstract

The invention discloses an explosion proof aluminous shell stamping forming die of a capacitor. A clamp thereof is movably installed in a clamp guide seat through a clamp slide block, a return spring is installed between the clamp slide block and the clamp guide seat, a driving piece and a driven piece are installed between an upper template and the clamp slide block, the clamp guide seat is provided with a clamp return limitation piece, and a flexible traction piece is connected between the clamp return limitation piece and the upper template; a feeding piece thereof is movably installed in a feeding piece guide seat through a feeding piece slide block, a return spring is installed between the feeding piece slide block and the feeding piece guide seat, a driving piece and a driven piece are installed between the upper template and the feeding piece slide block, and a feeding limitation plate which extends into a moving space of the clamp slide block is also connected to the feeding piece slide block. Compared with the prior art, the invention has the advantages of simple structure and convenient maintenance and can be conveniently installed on an ordinary punch machine to use so as to replace a special explosion proof aluminous shell stamping forming machine tool.

Description

technical field [0001] The invention relates to the technical field of stamping process equipment manufacturing, in particular to a mold for stamping and forming explosion-proof aluminum shells of capacitors. Background technique [0002] With the rapid development of electronic technology, the capacitor aluminum shell has been gradually replaced by the explosion-proof high-voltage capacitor aluminum shell. In the current production process of capacitor aluminum shells, the process equipment for manufacturing capacitor aluminum shells is generally manufactured by special stamping and forming machinery, such as "explosion-proof aluminum shell forming machine" (Chinese patent announcement number: 2043784U, announcement date: August 30, 1989 Japan), it is based on the existing punching machine, it is a four-station aluminum shell forming die fixture device consisting of upper and lower dies, including cold extrusion dies installed on the same template, explosion-proof slot dies...

AI Technical Summary

Problems solved by technology

[0005] In the above scheme, a template stroke limit adjustment mechanism composed of a template limit screw and a screw sleeve is installed between the upper template and the lower template, so that the upper template and the lower template move toward each other. The limit is precisely defined to overcome the pressing quality problem caused by the insufficient precision of the punch press; the explosion-proof punch is installed on an upper inclined block, and the upper inclined block and a lower inclined block are connected to each other through an inclined plane, so that The downward slanting block is connected and driven with the screw rod in an adjustment screw mechanism, so that the small adjustment of the explosion-proof mark protrusion is very accurate, so as to ensure the accuracy of the explosion-proof indentation depth pressed on the aluminum shell of the capacitor
