A continuous molding method for thin terminals

Abstract

The invention belongs to the technical field of stamping processing, and relates to a continuous forming method for thin terminals. The steps include: ①punching positioning holes, ②end pre-cutting, ③end chamfering, ④end finishing, ⑤edge trimming, ⑥blanking; step② Based on the positioning hole, multiple pre-cut holes are cut in the product forming area. The pre-cut holes include side pre-cut holes near the side of the metal strip. The outline of the side pre-cut holes includes several side-by-side raised structures , the raised height of the raised structure does not exceed 2mm, and the raised structure is chamfered and refined before trimming. This method can preform the chamfered part at both ends of the terminal with a thinner size, and then punch the rest of the terminal contour. The process is continuous and ensures the structural accuracy of the terminal chamfer, which meets the customer's precision. Require.

Description

technical field

[0001] The invention relates to the technical field of stamping processing, in particular to a thin terminal continuous forming method. Background technique

[0002] Terminals are metal products used to connect different electronic components, and are generally relatively slender parts. For the convenience of insertion, the ends of the terminals are often formed into a truss structure with a smaller outer side. The terminal is obtained from a metal strip with a thin sheet structure after multiple trimmings. If most of the outline of the terminal has been formed, then the end molding is not easy to handle, because the slender terminal structure will be produced when the end is pressed. deformation, and it is very difficult to carry out plastic positioning technology at this time. The thinner the terminal, the easier it is to break.

[0003] Therefore, it is necessary to design a new forming method to allow the terminal to obtain the desired structure quickl...
