Information
1. Classification according to the nature of the process
According to the nature of the process, the stamping die includes the following five types, namely, punching die, bending die, drawing die, forming die and riveting die.
1. Blanking die
Punching die refers to a die that can separate materials along a closed or open outline, such as blanking die, punching die, cutting die, slitting die, slitting die, trimming die, etc.
2. Bending die
The bending mold can cause the raw material to bend and deform, so as to produce a workpiece with a certain angle and shape.
3. Stretching die
Stretching die refers to a die that can make a blank sheet into an open hollow part, or further change the shape and size of the hollow part.
4. Forming mold
Forming mold refers to a mold that can directly copy the shape of the convex and concave mold to the blank or semi-finished workpiece, and the material itself only exhibits local plastic deformation.
5. Riveting and closing the mold
The riveting mold can use external force to connect the mold parts together and form a whole.
2. Classification according to the degree of process combination
According to the classification of different process combinations, stamping molds are divided into single process molds, composite molds, progressive molds and transfer molds.
1. Single process mode
Single-process mold refers to a mold that can only complete one stamping process during the working process of the press.
2. Compound mold
In one stroke of the press, the compound mold can complete two or more stamping processes at the same time on the same station.
3. Progressive die
Progressive die is also called continuous die. This type of die has two or more stations and can complete two or more stamping processes at different stations.
4. Transfer mode
The transfer mold can be transferred by a manipulator, which greatly improves production efficiency, while also reducing production and manufacturing costs and saving material costs. The transfer mold combines the advantages of the single process mold and the progressive mold, and has the characteristics of quality safety, stability and reliability.
3. Classification by processing method
According to the classification of processing methods, stamping dies can be divided into punching and shearing dies, bending dies and drawing dies.
1. Punching and shearing die
Punching and shearing dies complete their work through shearing. Shearing dies, blanking dies, trimming dies, full edge dies, punching dies and punching dies are all common forms of punching and shearing dies.
2. Bending mold
The bending mold can bend the flat blank material into a part with a certain angle and shape.
3. Drawing the mold
The drawing mold can make the flat blank into a seamless container with a bottom.
