Classification of product processing methods
According to different processing methods, dies are divided into five categories: stamping die, bending die, drawing die, forming die and compression die
1. Punching die: the work is completed through shearing action. The common forms include cutting die, blanking die, punching, trimming die, trimming die, drawing die hole and punching die
2. Bending die is to make a smooth blank into an angle and measure the shape, accuracy and output of the parts visually, but there are many different forms of dies, such as ordinary bending die, cam bending die, crimping die, arc bending die, bending die, punching in torsion bending die, etc
3. Wire drawing: the wire drawing die is a flat blank made of seamless container
4. Forming die: refers to various local deformation methods to change the shape of wool embryo, including convex sheet forming die, forming die, necking forming die, hole flange forming die and round edge forming die
5. Compression die: it makes the metal blank flow and deform into the required shape under strong pressure. This variety includes extrusion die, embossing die, stamping die and end die.
