Abstract

The invention discloses a process for producing a shielding case. The process sequentially comprises the following steps of: connecting a punch press with a lower die base fixedly, and then connecting the other side of the lower die base with a lower plate fixedly; then sequentially arranging a pre-punching module, a flashing module, a middle punching module, a bump beating module, a bottom punching module, a three-edge flanging module, a one-edge flanging module, a two-edge flanging module, an upper punching hole module, a hollow module, a levelling block and a two-edge shearing and bending module on the lower plate; placing a raw material on the lower plate, and then operating the machine; and processing the raw material by the pre-punching module, the flashing module, the middle punching module, the bump beating module, the bottom punching module, the three-edge flanging module, the one-edge flanging module, the two-edge flanging module, the upper punching hole module, the hollow module, the levelling block and the two-edge shearing and bending module sequentially to obtain the shielding case finished product. The process has the advantages of high production efficiency, and high planeness and quality of the product.

Description

technical field

[0001] The invention relates to a production process of a mold, in particular to a production process of a shielding cover, which is particularly suitable for flow production of the shielding cover by adopting a continuous mold. Background technique

[0002] With the rapid development of science and technology, the application of various high-tech electronic products is becoming more and more popular, but it also brings many problems, such as the electromagnetic interference problem encountered in the use of electronic products, which not only interferes with the electronic products The normal use, but also has an adverse impact on the surrounding environment. The function of the shielding cover is to form an electromagnetic shield to prevent electromagnetic interference.

[0003] The Chinese patent publication number is CN101227815A, and the invention patent disclosed on July 23, 2008 discloses a shielding cover and its manufacturing method. The shielding c...
