What are the processing molds for precision metal stamping parts?
Release time:2023-02-18Views:835

At present, precision metal stamping parts are widely used in family production and daily life. As we all know, metal stamping is a processing technology of forging materials through stamping machines and dies. It has the advantages of convenient operation, high stamping accuracy, mechanization and automation etc. It is a widely used processing technology at present. What are the processing molds for precision metal stamping parts? Let us give you a brief introduction.

Punching machine for processing metal stamping parts

1. The layout form and fixing technology of the punch: due to the different style and sizes of hardware punches, the processing and installation process of punches are also different, so the layout of punches used in actual production is various. The section style is circular and non-circular, the blade style is flat and beveled, and the layout is stepped, vertical, jacketed, etc. The fixing technology of punch includes shoulder fixing, riveting fixing, screw fixing, adhesive pouring fixing, etc.

2. Punch strength calibration: under normal circumstances, punch strength and rigidity are sufficient, and strength calibration is not required. However, when the section size of the punch is very small and the thickness of the cutting plate is very thick, it is necessary to check its bearing capacity and longitudinal bending function. Check whether the dangerous section size of the punch can meet the requirements of the enterprise, and prevent the punch from longitudinal consolidation and fracture.

The concave die is made of precision metal stamping parts.

There are a variety of female molds, with the overall inlay of female mold layout; Cutting edge also includes flat edge and oblique edge.

3. When using different screws and pins to fix the mold, ensure the distance between the screw hole (or sink hole) and the pin hole. The distance between screw hole, pin hole and mold side wall should not be too close, otherwise the service life of the mold will be affected.

The pattern layout of the concave die edge is divided into integral concave die and mosaic concave die.

4. When determining the overall concave surface size of die cutting, cutting force and transverse extrusion pressure can be encountered. Due to the difference in the form of die layout and fixing technology, the production of hardware stamping parts is usually determined by the thickness of the cutting plate and the surface size of the cutting sheet or the distance between the edge walls of the die hole.

With regard to the porous die, the distance between the blades should meet the requirements of different strength, which can prove that the wall thickness of the punch and the die of the composite die is very small.
