How does the design of metal stamping parts affect the product performance

The design of the hardware stamping parts factory should not only ensure good use function, but also have good process function, so as to reduce the material consumption, prolong the die life, improve the production rate, reduce the cost and ensure the quality of stamping parts. The main factors that affect the manufacturability of metal stamping parts are: shape, size, precision and material of stamping parts.
Dimensions of stamping parts
1. Requirements for blanking parts and punching parts
1) The shape of the material and the hole shape of the punching part should be simple and symmetrical. Regular shapes such as circle or rectangle shall be adopted as far as possible, and long slot or slender cantilever structure shall be avoided. Otherwise, it will make the mold manufacturing difficult and reduce the mold life. At the same time, the waste should be reduced to the minimum when the blanking parts are arranged.
2) The thickness of material must be considered in the structural dimension of blanking parts (such as hole diameter, hole distance, etc.).
3) Fillet arc connection is applied to the joint of straight line and curve on blanking part. In order to avoid the crack caused by stress concentration at the intersection angle.
2. Requirements for bending parts
1) The shape of bending parts should be symmetrical as far as possible, and the bending radius should not be less than the minimum allowable bending radius
2) The curved edge is too short to form, so the straight part H > 2 δ should be made. If h is required to be very short, it is necessary to set aside appropriate allowance to increase h, and then cut off the added metal after bending.
