Punching mould and punching method suitable for labtop keyboard frame

Abstract

The invention discloses a punching mould and a punching method suitable for labtop keyboard frame, wherein the mould comprises a group of blanking modules for blanking, a plurality of groups of coarse punching mouldes, and a group of fine punching modules for finally and finely processing. According to the punching method of the invention, the modules cooperated with each other, the side walls of the punched keyboard frame has enough euphotic belts, the positive and negative surfaces of a keyboard hole are acute angles and have no singk angle. At the same time, the punching mould of the invention uses a punching head and a lower mould inlet block processed by PG (profile grinding) optical grinding, and further is provided with a nitrogen spring so that the products have good euphotic belt and flatness.

Description

technical field [0001] The invention relates to a stamping die and a stamping method, in particular to a stamping die and a stamping method suitable for a notebook computer keyboard frame. Background technique [0002] Some keyboard frames of notebook computers are made of metal. Due to the high quality requirements of the keyboard frame, the processing accuracy and external dimensions of the metal keyboard frame are strictly controlled. However, the metal keyboard frame produced by the prior art often has a series of problems, such as: the punching force of the stamped metal part is relatively large, and the keyboard hole is prone to collapse; the surface of the punch and the lower die is not smooth enough, The side wall of the punched frame cannot guarantee enough bright bands, which affects the appearance of the product; the hole tolerance and the tolerance between holes of the punched product are difficult to meet the required accuracy. [0003] The quality of the stamp...

AI Technical Summary

Problems solved by technology

However, the metal keyboard frame manufactured by the prior art often has a series of problems, such as: the stamping force of the stamped metal part is relatively large, and the keyboard hole is prone to collapse; the surface of the punch and the lower die is not smooth enough, The side wall of the punched frame cannot guarantee enough bright bands, which affects the appearance of the product; the hole tolerance and the tolerance between holes of the punched product are difficult to meet the required accuracy

[0003] The quality of the stamping parts is directly related to the design and manufacture of the mold, and the metal keyboard frame of the notebook computer manufactured by the existing mold and manufacturing method is difficult to meet the aforementioned high requirements, and the quality of the product needs to be improved
