Process plan and technical requirements of stamping parts

Stamping parts use the Hehe theory to achieve less waste and no waste layout and blanking. Under the premise that the design technical requirements of precision stamping parts and the parts have no rigid regulations on the material fiber direction, in addition to the general sheet layout principles (such as in order to reduce strips) When cutting narrow strips, it should be carried out along the longitudinal direction of the board; the parts should be arranged into wide strips as much as possible to reduce the number of cutting and the feeding distance during stamping; use side pressure plates to feed as much as possible, and try not to set Feeding from the knife can reduce the edge and strip width), and should try to use less waste, no waste layout and blanking technology. Stamping parts change the shape of the parts to achieve less waste and no waste. Under normal circumstances, the product designer designs the parts according to the use requirements and the technologists prepare the process according to the part product drawings. This is a matter of course. However, sometimes materials are sent into the waste bin by the hands of designers, causing waste. Therefore, when analyzing the stamping process of the parts and selecting the process plan, appropriately change the shape of the part so that the changed shape of the part can become a combined figure, and there is no gap between parts and parts and between parts and blanks. It can realize the blanking with less waste and no waste, which can not only increase the material utilization rate (up to 100%), but also increase the production efficiency, reduce the processing difficulty of the die, and help improve the product quality. In actual production, due to the limitation of sheet specifications, some parts generate a lot of waste in the blanking and layout, resulting in waste. In large-scale stamping production, the blanks of two or more materials with similar indicators and coordinated output can be nested and punched on the same plate, thereby reducing or even eliminating blanking waste and reducing material consumption . Generally, the following principles should be followed when selecting materials for automotive stamping parts: a. The selected material should first meet the performance requirements of auto parts; b. The selected material must have better process performance; c. The selected material must have a better economy Sex.
