Embodiment 1

[0044] see figure 1 , a workpiece stamping process for processing electronic products, comprising the following steps:

[0045] S1. Inspection and storage of raw materials and plates;

[0046] S2. Use the shearing device to cut the raw material sheet into a sheet with a composite size requirement, and perform surface treatment on the sheet;

[0047] In S2, surface treatment includes the following steps:

[0048] S21. Pickling treatment: put the sheet into the pickling tank, add pickling liquid into the pickling tank, pickle at 30°C for 120-150min, and clean the sheet after the pickling;

[0049] S22. Passivation treatment: put the pickled sheet into a passivation tank, add a passivation solution to the passivation tank, and passivate the sheet at 20°C for 30 minutes;

[0050] S23. Cleaning and drying: the passivation-treated sheet is rinsed three times under a high-pressure water gun, and dried to complete the surface treatment.

[0051] Wherein, the pickling solution incl...

Description

technical field [0001] The invention relates to the technical field of electronic product processing, and more specifically, relates to a workpiece stamping process for electronic product processing. Background technique [0002] Electronic products are related products based on electric energy, mainly including: watches, smart phones, telephones, televisions, DVD players, video recorders, camcorders, radios, tape recorders, combination speakers, CD players, computers, game consoles, mobile communication products, etc. Because the early products were mainly based on electronic tubes, they were named electronic products. [0003] Stamping processing is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet to deformation force and deform in the mold, so as to obtain product parts of a certain shape, size and performance. Sheet metal, mold and equipment are the three elements of stamping processing. According ...
