Methods for improving the quality of metal stamped parts.

(1) Improve process methods
In the drawing direction, try to make the contact area between the punch and the workpiece as large as possible, use a reasonable shape of the pressing surface and the force of the workpiece holder, so that the resistance of all parts of the pressing surface is uniform and moderate, reduce the drawing depth, open technological holes and technological notches, etc. .
(2) Use standard raw materials.
Strictly apply screen stamping plates and use plates that match the process to avoid stress deformation caused by plate performance problems.
(3) Structural analysis of stamped parts.
When designing metal stamping parts, it is best to have a larger radius at each corner, a smaller actual depth of the curved surface in the drawing direction, uniform depth throughout, simple shape and smooth changes, etc.
(4) Metal stamping mold design
Measures such as properly designed draw rolls, larger mold fillets, and reasonable clearances between punch and die can be taken.
(5) Use special stamping oil.
High quality special stamping oil can effectively avoid cracks, burrs and other problems in stamped parts by releasing extreme pressure agents during the stamping process, and can greatly improve the surface quality and efficiency of the workpiece process.
