Abstract

The invention discloses a punching method of a sheet metal part. The punching method comprises the steps of providing the sheet metal part, wherein the sheet metal part is provided with a first surface and a second surface which are relative, and the sheet metal part is defined to be provided with a base material area and a cutting area; and then applying a first punching technology on the sheet metal part, so as to protrude the first surface of the base material area by the cutting area; and finally, applying a second punching technology on the sheet metal part, so as to oppositely protrude the second surface of the base material area by the primary cutting area which protrudes the first surface of the base material area, and generate a fracture surface between the cutting area and the base material area.

Description

technical field [0001] The invention relates to a mechanical processing method, in particular to a stamping method for sheet metal parts. Background technique [0002] With the continuous advancement of science and technology, the daily necessities of modern people are all developing towards digitization and informationization. Taking a desktop computer as an example, a host case includes a main board and a sound card, a display card and a network card connected to the main board. The above-mentioned interface cards will be fixed on a fixed frame on one side of the main body casing, and the connection jacks of these interface cards will appear outside through a plurality of windows on the fixed frame, so as to facilitate the insertion of external lines. Assume. [0003] In addition, in order to meet the expansion requirements of the interface cards in the host casing, a plurality of spare windows are reserved on the fixing frame for use by the interface cards to be expande...
