1, blanking die
In stamping production, the die used for blanking is called blanking die. The main task of blanking die is to separate materials.
2. Deep stamping die
Generally, it refers to various dies for drawing metal wires and drawing dies for drawing optical fibers. All drawing dies have a hole with a specific shape in the center, such as circle, square, octagon or other special shapes.
3. Bending die
Bending die refers to a stamping die that bends a blank or semi-finished product into a certain shape. Bending dies have their own characteristics, such as punches and dies, which sometimes need to swing and rotate in addition to general movements. The structural form of bending die should be selected according to the shape, precision requirements and production batch of bending parts.
Second, the use is different.
1, blanking die
Punching die is mainly used for blanking and punching all kinds of plates. The working part of the die is the punch and the cutting edge of the die, which bears the impact force, shear force, bending force and strong friction force of the sheared material when working. Therefore, the performance requirements of stamping die mainly refer to the performance requirements of die cutting edge.
2. Deep stamping die
Wire drawing dies are widely used, such as high-precision wires used in electronic devices, radars, televisions, instruments and meters, aerospace, and commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires and various alloy wires, all of which are drawn by diamond wire drawing dies. Because the diamond wire drawing die is made of natural diamond, it has strong wear resistance and long service life.
3. Bending die
It is widely used, such as many shoe covers on automobiles, cabinet frame parts of automobiles, handles on motorcycles, foot stands, support parts on bicycles, and handles as small as door buckles and clips (iron clips).
Third, the structure is different.
1, blanking die
1) process section
Process parts directly participate in the completion of stamping process and interact with blank directly. The process part includes a working part, a positioning part, a pressing part, a discharging part and a discharging part.
2) Structural components
Structural parts do not directly participate in the completion of the process, nor directly interact with the blank, but only play a role in ensuring the completion of the process or improving the function of the mold. The structural part includes guiding part, fixing part, fastening part and other parts.
2. Deep stamping die
According to the working nature, the structure of wire drawing die core can be divided into five parts: entrance area, lubrication area, working area, setting area and exit area. The inner diameter profile of the wire drawing die is very important, which determines the tension required to compress the wire and affects the residual stress in the wire after drawing.
3. Bending die
The structure of bending die is similar to that of general blanking die, and it is divided into upper and lower parts. It consists of punch and die, positioning, discharging, guiding and fasteners.
