The production process of appliance input socket pin

Abstract

The invention discloses a manufacturing process of appliance input socket pins. The manufacturing process comprises the following steps of: step 1, punching a process hole in a metal sheet; step 2, processing a head portion, a tail portion and an intermediate portion on the metal sheet; forging and pressing a first step surface and a second step surface; step 3, punching a function hole and cutting two V-shaped notches; step 4, cutting a first group of inclined surfaces at the end surface of the tail portion by using a knife edge; step 5, forging and pressing a second group of inclined surfaces on the bottom surface and the top surface at the end of the head portion, and forging and pressing a third group of inclined surfaces on the bottom surface and the top surface at the end of the tail portion; step 6, cutting a fourth group of inclined surfaces at the end surface of the tail portion by using the knife edge; step7, cutting the overall product from the metal sheet by using the knife edge; and step 8, inserting the metal terminal into a jack in a main body plastic component. The manufacturing process disclosed by the invention realizes automation, a product shaped by extrusion forging is stable in size, and the internal metal structure is good and low in heat generation when current with a specified upper limit value passing through.

Description

technical field [0001] The invention relates to the field of appliance input sockets, in particular to a production process for plug pins of appliance input sockets. Background technique [0002] Appliance input socket pins are used on household and similar coupler standard leaflets, which are widely used in various fields such as household and similar electrical appliances, instruments and meters, communication equipment, and industrial equipment. [0003] At present, the pins of appliance input sockets are generally produced by stamping and forming traditional crafts after secondary processing of special-shaped copper materials or ordinary copper materials. It is difficult to achieve the purpose of automatic production for special-shaped materials or ordinary copper materials after secondary processing, and the required special-shaped copper materials are processed by special milling. In order to ensure the milling accuracy, the copper material can only be processed withi...

AI Technical Summary

Problems solved by technology

[0004] Special-shaped copper raw materials or common copper materials are stamped and formed after secondary processing, and then riveted with V-line incisions on the plastic shell. It is easy to crack when riveting, so it can only be molded by inserting parts into the mold of the injection molding machine (Insertmolding) , because it is necessary to manually put the processed hardware pins into the plastic mold, so it can only be operated manually, and automatic production cannot be realized
