Sheet metal parts design
(1) In order to ensure the material utilization rate and the minimum number of die changes in bending, the thickness specifications of plates on the same structure shall not exceed three at most. For structures with high strength requirements, the method of pressing reinforcement on thin plates can be adopted;
(2) It should be avoided that the unfolding size of parts is equal to the outline size of raw materials: the shape of plates supplied in the market is not square. If the unfolding size is equal to or very close to the outline, there is no allowance for the whole square, and the product size after direct processing has errors, which will affect the installation and use.
(3) For non-sprayed plates with decorative surface requirements, the decorative surface and grain direction shall be considered in combination with the plate materials. For any purpose, the plate with decorative surface shall be used and the grain direction shall be required. For non-exposed parts, the processing process shall be protected from scratch, and the welding joints shall be treated after welding. The processing volume is large. Therefore, in order to ensure the utilization rate of materials and reduce unnecessary processing, The direction of decorative surface or other materials without decorative surface can be ignored.
