Embodiment

[0059] In this embodiment, a copper cap manufacturing process is proposed, and the copper cap is manufactured through the copper cap manufacturing process. Among them, such as figure 1 with figure 2 Shown is a schematic diagram of a finished copper cap 100 .

[0060] A manufacturing process of a copper cap 100, comprising the steps of:

[0061] S1: Die-cutting process: Die-cut the copper sheet into several parts.

[0062] S2: the initial punching process, the initial punching is performed on several copper sheets at the same time to form several concave structures.

[0063] S3: preforming process, several concave structures are stamped multiple times simultaneously, and inner protrusions 101 and outer grooves 102 are formed on each of the concave structures to obtain some semi-finished products; each stamping makes the outer diameter of the inner protrusions 101 And the inner diameter of the outer groove 102 gradually becomes smaller, and at the same time, each stamping m...

Abstract

The invention discloses a copper cap manufacturing process and a die used for manufacturing copper caps. The copper cap manufacturing process comprises a punching working procedure which enables a copper sheet to be punched into a plurality of parts, an initial punching working procedure conducting initial punching the multiple parts of the copper sheet to form a plurality of concave structures, apreforming working procedure conducting repeated stamping on the multiple concave structures, forming internal protrusions on all concave structures, and obtaining a plurality of semi-finished products, wherein each time of stamping enables the outer diameters of the internal protrusions to be gradually decreased, and enable time of stamping enables the wall thicknesses of the concave structuresto be thinned, a stretching forming working procedure used for stretching the multiple semi-finished products at the same time to obtain a plurality of advanced-finished products, and a blanking working procedure conducting blanking on the semi-finished products to enable the semi-finished products to break away from the copper sheet, and then obtaining finished products. The copper cap manufacturing process is simple and reasonable, the multiple copper caps can be produced within one period, the production efficiency of the copper caps is greatly improved, the production cost is reduced, andthe copper cap manufacturing process and the die are suitable for industrialized and batched production of the copper caps.

Description

technical field [0001] The invention relates to the technical field of copper cap production, in particular to a copper cap production process and a mold for producing the copper cap. Background technique [0002] In order to protect the safety of the circuit, a fuse is provided in the circuit, and a copper cap is installed on the fuse. [0003] In the prior art, the precision of the mold for producing the copper cap is low, which leads to a high scrap rate of the copper cap product, which leads to an increase in production cost; in addition, the existing mold can only produce one copper cap product in one cycle, and the production efficiency is low. Contents of the invention [0004] The object of the present invention is to overcome the defects of the prior art, and provide a manufacturing process of a copper cap and a mold for manufacturing the copper cap, so as to solve the problems in the prior art. [0005] In order to solve the above problems, the invention provide...
