Design features of stamping die for automobile stamping parts

Automobile stamping parts are stamping parts applied to automobiles, which are very important to the role of automobiles. The automotive industry also has very high requirements for automotive stamping parts, including precision and production process control. If a stamping parts processing plant wants to produce qualified automotive stamping parts, it is necessary to design a reasonable stamping die. Next, Precision will introduce the design features of stamping die for automotive stamping parts. 1. Large structure specifications. In addition to the fact that the stamping parts themselves are relatively large, the precise positioning of the products of the stamping parts, the installation structure of the mold, the orientation of the left and right molds, the lifting, rotating and transportation devices of the mold need to expand the structural specifications of the punching mold. 2. The basic parts are frame structure. The structure specifications of the stamping die for automobile are large. In order to reduce the net weight of the mold and improve the performance of the production process, the design scheme is generally a double-layered level composed of two prefabricated components, and a frame shear wall composed of vertical reinforcement in the middle. Generally, the structural parts (mold bases) of general punching dies often use standardized solid core plates. 3. Low standardization level. Generally, the standardization level of die design and the amount of standard parts used are much larger than that of stamping die. For example, a general punching machine die can be installed with standard parts, while at least the structural parts of the automotive stamping die are non-standard parts. 4. The relative quality of mold raw materials is relatively low. For the raw materials of the working parts (die base, cavity, edging ring) of the stamping parts with a service life of 400,000 times or less, generally, pig iron with a higher compressive strength can be used. However, alloy steel is more common in the work of general die. [Recommended recommendation] Learn more: The advantages of electrolytic polishing of the motor housing.
