Metal stamping parts are widely used in various fields of our life, including some electronic devices, auto parts, decorative materials and so on. We usually say that the stamping parts processing generally refers to the cold stamping parts. For example, a piece of iron plate, if you want to turn it into a fast food plate, you must first design a set of mold. The working surface of the mold is the shape of the plate. If you press the iron plate with the mold, you will become the plate you want. This is cold stamping, that is, stamping the metal materials directly with the mold.
According to the process properties, the classification of metal stamping dies can be divided into:
1. Single engineering stamping die: using single station die to complete the required stamping operation is the simplest stamping die structure, most of which are manually operated.
2. Compound engineering hardware stamping die: using two groups of punches and mother die of single station mold to complete two or more stamping processes, which is the best stamping die for product dimensional accuracy control.
3. Progressive die: the strip feeding is in a continuous state in the stamping process. The strip is moved one pound pitch drop by one by one by using the feeding device, which is used for mass rapid production of square float. This kind of die can be divided into three categories: continuous blanking die, continuous die with bending engineering, and continuous drawing die.
4. Transfer dir (transfer DIR) is one of the continuous stamping processing methods, and the biggest feature of the continuous stamping die is that the blank is in the separation state in the stamping process, using the robot arm or the macro feeding mechanism to move a set feeding pitch step by step, and complete the punching production of products through multi station engineering.
Metal stamping is the use of punch and die iron, aluminum, copper and other plates and foreign materials to deform or fracture, to achieve a certain shape and size of a process.
