A. Stamping die A die that separates materials along a closed or open contour line. Such as blanking die, punching die, cutting die, cutting die, trimming die, cutting die, etc.
B. Bending die is a die that bends a blank or other blanks along a straight line (bending line) to obtain a workpiece with a certain angle and shape.
C. Drawing die is a die that makes a blank plate into an open hollow part or further changes the shape and size of the hollow part.
D. The forming die is a die that directly replicates and forms a blank or semi-finished workpiece according to the shapes of the male die and the female die, and the material itself only produces local plastic deformation. Such as expanding die, necking die, flaring die, wavy forming die, flanging die, shaping die, etc.
2. Classification according to the degree of process combination
A. Single-process stamping die A stamping die that only completes one stamping process in one stroke of the printing machine.
B the compound die has only one station, and in one stroke of the press, two or more stamping processes are simultaneously completed at the same station.
C. The progressive die (also called the continuous die) has two or more stations in the feeding direction of the blank, and in one stroke of the press, two or more stamping processes are continuously completed at different stations.
3, according to the product processing method classification
According to the different processing methods of products, dies can be divided into five categories: stamping and shearing dies, bending dies, drawing dies, forming dies and compression dies.
A. Punching and shearing die: the work is accomplished by shearing. The common forms are shearing die, blanking die, punching die, trimming die, edging die, hole drawing die and punching die.
B. Bending die: bending a flat blank into an angle. According to the shape, precision and output of parts, there are many different types of dies, such as common bending die, cam bending die, curling die, arc bending die, bending punching die and torsion die.
C, die drawing: die drawing is to make a flat blank into a seamless container with a bottom.
D. Forming die: refers to changing the blank shape by various local deformation methods, including convex forming die, curling forming die, necking forming die, hole flange forming die and round edge forming die.
E. Stamping die: The metal blank is deformed into the required shape by strong pressure, and its types include extrusion die, embossing die, embossing die and end stamping die. [Edit this paragraph] III. Typical Structure of Mould Usually, the mould consists of two types of parts:
The first type is process parts, which directly participate in the completion of the process and are in direct contact with the blank, including work parts, positioning parts, unloading pressing parts and so on.
The second type is structural parts, which do not directly participate in the process completion or directly contact with the blank, but only play the role of ensuring the process completion of the mold or improving the function of the mold, including guide parts, fasteners, standard parts and other parts, as shown in table 1. 1.3. It should be pointed out that not all stamping dies must have the above six parts, especially single-process dies, but the working part and the necessary fixed part are indispensable. /view/88 1699.htm Go in and have a look.
