Drum shield, how to design shield + 3.0 precision stamping design system

Drum shields, mobile phones, transformers, routers and other products, the foreign white copper shields selected, have some experience summarized by engineers in its function, design, and installation. So what experience have been summed up? Let me know about it with you: 1. First of all, the cover of the white copper shielding cover is mostly made of stainless steel. It cannot be stretched, but can only be bent; the shielding bracket can be stretched, but the bracket material is thick Must be 0.20mm, height ≥1.25mm; 2. The minimum inner R angle at the corner of the nickel-nickel copper shield tensile part must be at least 0.65mm, the minimum outer R angle must be at least 1.0mm, and the welding method must be flanged Above 0.20mm; 3. The cutting edge width of the flanges around the white copper shielding cover is Bu003d0.2mm (1 times the material thickness), which increases the flatness stability; the inner round corner R1 of the outer frame can be as small as R0.65mm, the best R1.0mm or more is better, the drawing forming can not have a right-angle sharp turn, otherwise the drawing will break; 4. The outer corner of the outer frame R2 u003d 1.0 mm, preferably R1.5mm or more is better; A size Not less than 0.7mm, preferably 1.0mm or more. Hardware, 15 years of focusing on drum shielding cover, 20,000+ sets of customized stamping die production experience, monthly processing capacity of 100+ sets of molds, hundreds of precision processing production equipment, daily production capacity of 3 million punches, and silk-like stamping accuracy up to 0.01 mm, the raw materials are imported and the original national standard, and 16 quality inspections are strictly controlled.
