Take you know when the car stamping product drawing and forming

Manufacturer of automotive stamping parts installed on the pressure die exert force on the material, make its produce a separation or plastic deformation, and the stamping products conform to the standard, and in the process of production, the reasonable drawing direction should comply with the following principles as well as the difference between a and forming the difference: 1. To ensure that the car stamping punch to the workpiece to deep drawing parts in the process of a deep drawing is complete, there should not be out of the reach of punch; 2. At the beginning of the punch and the blank contact state to good, contact area as far as possible big and close to the central area, punch surface contact point of blank at the same time more and scattered, prevent semi-finished channeling move; 3. As far as possible, reduce the depth of the drawing, make each part uniform depth distribution; When parts forming depth is more than 10 mm, had better use drawing way, avoid crowded phenomenon, can consider to use forming way when less than 10 mm; 4. Drawing general addendum surface and need to make a complete process, and is a closed shape, forming only need to make local craft, need not all; 5. Automotive stamping parts close to the closed state by drawing best way to open the can use forming way; The above article is derived from the metal stamping parts, automotive stamping parts processing customized 18 years, reprint please indicate the source. 【 Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts?
