Parts of Stamping Mould
1. Stamping die
The stamping die, also known as the stamping mold, is the common name for the tool for stamping blanking, drawing, shallow and bending of metal parts. It is the most widely used processing tool in the metal processing industry. Generally, the stamping die consists of several parts: the upper and lower dies, the inserts, the nibs, the back-pressure plates, the guide posts and the sleeves. All of these components interact with each other during the metal stamping process to form a tool.
2. Die plate
The die plate, also known as the die base, is the basic part of the stamping die, which is used to position, fix and connect other parts of the die. It is usually made of hot-rolled or steel forging by welding. After numerical control processing and heat treatment, the die plate is processed into a precise three-dimensional structure, and a precise three-dimensional structure is formed on the die plate. The heights of the grooves and corners on the die plate are easy to adjust and possess good interchangeability.
3. Die cavity
The die cavity, also known as the die, is the main working part of the stamping die. It is used to hold and shape the metal blank and cut out the desired shape and size of the workpiece. It is mainly composed of punch and die. The punch is responsible for adding force to the blank and has a variety of shapes; the die is used to cut and shape the blank and has a variety of shapes. During the pressing process, the die cavity and the blank form a relatively rigid closed system, and the blank is subjected to a certain shape under the action of external forces.
4. Heating device
The heating device, also known as the hot-pressing device, is an auxiliary device for the stamping process, which is mainly used to heat the stamping die, so as to reduce the difficulty of stamping and ensure the accuracy and quality of the workpiece. Generally speaking, the heating device usually consists of three parts: a heating element, a heating control device and a temperature control device. The heating element is mainly made of resistive heating element materials, and its temperature is controlled by the control device. The temperature control device is mainly used to measure the temperature in the process, so as to reach the desired temperature accurately.
5. Lubrication system
The lubrication system, also known as the die lubrication system, is an auxiliary device of the stamping die to reduce the friction between the blank and the stamping die and extend the service life of the stamping die. The lubrication system is mainly divided into manual and automatic two types, and can be divided into two categories according to the lubrication type: oil mist lubrication system and oil-soluble lubrication system. In short, it can provide the right amount of lubricant for the stamping die to reduce the wear of the stamping die and prevent the occurrence of sticking pieces.
6. Other accessories
In addition to the above die components, the stamping die also needs to be equipped with some necessary accessories, such as guide posts, guide sleeves, back-pressure plates, etc., which can ensure the accuracy and efficiency of stamping. The guide posts can accurately locate and position the blank, preventing the blank from being displaced during the stamping process; the sleeves play a role in guiding and protecting the guide posts; the back-pressure plates can prevent the blank from rising when the punch is pressed, which is beneficial to the forming of the blank.
Conclusion
The various parts of the stamping die mentioned above play an important role in the stamping process. With its help, the stamping die can shape and cut out the workpiece of the desired size and shape, thereby realizing the exchange between energy and kinetic energy. With the development of new technologies and materials, stamping die manufacturing technology is becoming more and more advanced. In the future, it will be able to better serve the development of the national economy and production efficiency.
