Embodiment Construction

[0022] Electrolytic capacitor aluminum shell multi-station continuous drawing process with material, the steps are:

[0023] 1) According to the number of horizontal rows of capacitor aluminum casings (generally 3-20 rows), carry out the layout of the aluminum casing material, and determine the required strip width; this is because the flat aluminum material is stamped and drawn It is a three-dimensional cylindrical aluminum shell, which is a process in which the diameter gradually decreases and the height gradually increases; therefore, the area of ​​the plane aluminum material used is larger (and thicker) than the projected area of ​​the aluminum shell, which can be calculated by empirical formula Sure.

[0024] 2) Punch out contour cuts for each row of aluminum shell materials on the strip, each contour cut consists of 2-6 discontinuous curved fractures, and part of the strip surrounded by each contour cut passes through the subsequent steps Punched into an aluminum shell,...

Abstract

The invention relates to an aluminium case deep drawing technology of a capacitor and a deep drawing module. The invention is to provide a technology capable of synchronously punching multi-strand aluminium cases with good product quality and high production efficiency. The other purpose thereof is to provide a deep drawing module with compact and applied structure, good product quality, high production efficiency and low cost. The technical solution is aluminium case multi-station strip continuous deep drawing technology of electrolytic capacitor, comprising the steps of: 1) determining strip width according to stock layout of materials; 2) punching outline notches on the strip; 3) punching aluminium cases on strip in the middle of each outline notch; 4) separating the aluminium cases from the strip. The aluminium case multi-station strip continuous deep drawing module of electrolytic capacitor comprises convex modules of an upper module base and concave modules of a lower module base. The convex modules are arrayed into continuous row, and convex module holes are one-to-one corresponding to each other. 3 to 20 rows of convex modules are mounted on the deep drawing module. A notch module is respectively mounted in the front of each row of the convex module so as to form an outline notch.

Description

technical field [0001] The invention relates to an aluminum shell deep-drawing process and a deep-drawing die, in particular to a capacitor aluminum shell multi-station continuous deep-drawing process with material and a multi-station continuous deep-drawing die with material. Background technique [0002] The inventor once disclosed a continuous mold of electrolytic capacitor aluminum shell with material in the Chinese patent application document (application number 200420089948.0); The dies on the die fixing plate correspond to the dies up and down with the punches one by one, and the punches are arranged in a row by the processes of drawing, punching explosion-proof grooves, shaping and cutting. This kind of process can punch qualified products continuously and effectively, but the punching efficiency still needs to be improved. Contents of the invention [0003] An object of the present invention is to overcome the above-mentioned deficiencies in the background techno...
