Classification according to process attributes
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 blank plates into open hollow parts or further changes the shape and size of the hollow parts.
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.
E. riveting die is to connect or lap the participating parts in a certain order and way by external force, and then form a whole.
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.
D. The transfer die combines the characteristics of single-process die and progressive die, and realizes the rapid transfer of products in the die by using the manipulator transfer system, which can greatly improve the production efficiency of products, reduce the production cost of products, save material costs, and have stable and reliable quality.
According to the processing method of the product.
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.
