Hardware stamping dies can be divided into 3 categories according to different features
A: According to the deformation characteristics of the material classification of the drop die, punching die, cut-off die, cutting die, cutting edge die, bending die, deep-drawing die, molding die, embossing die, cold extrusion die and so on.
Second: according to the nature of the process classification of blanking die, bending die, deep drawing die and forming die. Punching die along the closed or open contour line so that the material to produce a separation of the mold. Bending die so that sheet blanks or other blanks along the straight line (bending line) to produce bending deformation, so as to obtain a certain angle and shape of the workpiece mold.
Third: according to the degree of process combination classification of single-process mold, composite mold and progressive die. Single-process mold in a press stroke, only one stamping process is completed in the mold. Composite mold only one station, in a stroke of the press, in the same station at the same time to complete two or more stamping process mold.
Progressive die (also known as continuous mold) in the blank feeding direction, with two or more stations, in a stroke of the press, in different stations one by one to complete two or more stamping process mold.
Hardware stamping die manufacturing materials are steel, cemented carbide, steel junction carbide, zinc-based alloys, low melting point alloys, aluminum bronze, polymer materials and so on. At present, the vast majority of the materials for manufacturing stamping die to steel-based, commonly used mold working parts of the types of materials are: carbon tool steel, low alloy tool steel, high carbon and high chromium or chromium tool steel, medium carbon alloy steel, high-speed steel, base steel and carbide, steel cemented carbide and so on.
