Drawing parts are workpieces obtained by stretching and deforming sheets by mechanical equipment. Now we will introduce the production standards of drawing parts.
1. The first-wall surface, bottom surface and wall surface of the deep-drawing part, and the corner radius of the four corners of the rectangular part should be appropriate. mm2rd1, mm5.1r2d.
2. The shape of the stretched part should be simple and symmetrical, and it should be stretched at one time as much as possible.
3. For parts that need to be stretched many times, on the premise of ensuring the required surface quality, traces that may be produced on the inner and outer surfaces should be allowed.
4. On the premise of ensuring the assembly requirements, the side wall of the deep drawing part should be allowed to have a certain slope.
5. The dimensions of the deep-drawn parts should be marked with their outer or inner dimensions, and the inner and outer dimensions should not be marked at the same time. With trapezoidal deep-drawing parts, the dimension in the height direction should generally be based on the bottom. If the upper part is the benchmark, the height dimension is not easy to guarantee.
6. The distance from the hole on the bottom or flange of the deep drawing piece to the side wall should be appropriate.
