Deep Drawing Process in Hardware Stamping Parts Factory

Deep drawing process in hardware stamping parts factory
Metal stamping parts manufacturers need to pay attention to some things when processing deep-drawn parts to ensure and improve the quality of deep-drawn parts. Let's find out what these things are.
1. The design of the deep-drawn parts should be as simple and symmetrical as possible, and can be drawn and formed in one step;
2. The wall thickness tolerance or thinning requirements of the deep-drawing parts should generally not exceed the wall thickness variation pattern of the deep-drawing process;
3. When the deformation of the metal stamping parts is too large in one drawing, multiple drawings should be used to avoid cracking;
4. On the premise of ensuring the assembly requirements, a certain inclination of the side wall of the deep-drawn part should be allowed.
5. When there is a hole on the bottom or flange of the deep-drawn part, the distance from the edge of the hole to the side wall should meet certain requirements, otherwise the hole will be deformed;
6. The rounded corners at the bottom and wall of the drawn part, the flange and the wall, the four corners of the rectangular part, etc. should meet different angle requirements, otherwise the shaping process should be added;
7. When drawing the drawing of the deep-drawn part, the radial dimensions of the deep-drawn part should only be marked with the outer dimensions or the inner dimensions, but not both the inner and outer dimensions.
