(1) Stamping process terminology 1: Blanking: It is a stamping process that separates materials along a closed contour. The separated materials become workpieces or process parts, most of which are planar. 2: Deep drawing: It is a stamping process that turns straight wool or process parts into hollow parts, or further changes the shape and size of hollow parts. During deep drawing, the hollow part is mainly formed by the material located outside the bottom of the punch mold flowing into the concave mold. 3: Shaping: It is a stamping process that relies on material flow to change the shape and size of the workpiece in a small amount to ensure the accuracy of the workpiece. 4: Punching: It is a stamping process that separates waste materials from materials or process parts along a closed contour to obtain the required holes in the material or workpiece. 5: Turning: It is a stamping process that turns the material into a side flange around the inner hole. 6: Trimming: It is a stamping process that uses a die to trim the edge of the hill forming process so that it has a certain diameter, a certain height or a certain shape.

5: Turning: It is a stamping process that turns the material into a side flange around the inner hole. 6: Trimming: It is a stamping process that uses a die to trim the edge of the hill forming process so that it has a certain diameter, a certain height or a certain shape. 7: Flanging: It is a stamping process that turns the edge around the contour curve into a short side. (2) Terminology of grinding and die parts 1. Lower die: It is the lower part of the entire mold, that is, the die part installed on the work surface of the press. 2. Lower mold base: It is a plate-shaped part on the lower mold floor. It is directly fixed on the backing plate on the press work surface. 3. Upper mold: It is the upper part of the entire mold, that is, the die part installed on the slider of the press. 4. Upper die base: It is a plate-shaped part above the upper die. It is close to the pressure gauge slider during operation and is fixed with the press slider through the die handle or directly. 5. Punch: It is the graphic working part in the die that directly forms the punched parts, that is, the part that acts as the working surface. 6. Concave die: It is a concave working part in the die that directly forms the punched parts, that is, the part with the inner shape as the working surface. 7. Pressing plate: It is a part in the stamping die used to hold stamping materials or process parts to control the flow of materials. In the drawing die, the pressing plate is mostly a pressing ring. 8. Pressing rib: It is a rib-like protrusion used to control the flow of material in the drawing die or drawing die. The pressing material can be the local structure of the sliding pressing ring of the die, or it can be embedded in the die or A separate part in the press ring. 9. Blade slope: It is the slope of each side of the blade wall of the punching die hole. 10. Blade wall: It is the slope of each side of the blade wall of the punching die hole. 11. Guide plate: It is a plate-shaped part with an inner hole that accurately slides with the punch. It is guided with the inner hole to ensure that the punch Aligned with the die and has unloading function. 12. Guide pillar: It is a cylindrical part that provides precise guidance for the relative movement of the upper and lower mold bases. Most of them are fixed on the upper mold base and used in conjunction with the guide bushing.
