In order to protect normal production, improve the quality of stamping parts, reduce costs, and extend the life of the die, the die must be used and maintained reasonably, and the die "three inspection" system must be strictly implemented (inspection before use, inspection during use and inspection after use), and do Good die and maintenance work.

Its main work includes the correct installation and debugging of the mold; strictly control the depth of the punch into the concave mold; control and correct the bottom dead point extension of the upper mold in the processes of bending, cold extrusion, and shaping; timely re-grinding and polishing the cutting edge of the chess set ; Pay attention to keep the chess set clean and reasonable lubrication, etc. The edge of the punch edge is trimmed with a bevel or arc. This is an effective way to reduce cushioning power. By reducing the buffer cutting force, the tensile force on the material on the side of the die can be reduced, so as to achieve the effect of suppressing the turning and twisting of the stamping parts.

The correct use and reasonable maintenance of molds are of great importance for improving the life of molds.
