In Stamping Processing, How to Control the Cost of Automotive Sheet Metal Stamping Parts?

1. The technology of sheet metal stamping parts affects the manufacturing cost of auto parts

The car body is made of various stamped parts and sheet metal parts by welding, and these parts are basically produced by the stamping technology. On a car, more than 60% of the parts are stamped parts. In the cost of stamping parts, material costs generally account for more than 60%. Therefore, it is very important to discuss the cost control measures in the processing of automobile sheet metal stamping parts, select the appropriate technology of sheet metal stamping parts, optimize the mold mechanism, reasonably select the mold materials and fully consider the material utilization rate, etc., which is of great significance to vehicle cost control.

The choice of technology of sheet metal stamping parts directly affects the cost of structures and parts in automobile stamping production, and the economical quality reflects the pros and cons of the stamping technological plan. In terms of reasonable selection of stamping technology, processing plants of stamping parts have accumulated a lot of experience, and there are many measures that can be used to achieve cost control.

2. How to control the cost of automobile sheet metal stamping parts in stamping processing?

(1) Give priority to the technological plan of installing the cutter on the drawing die. Reducing the process of sheet metal stamping parts is an important way to control the cost of stamping. There are many ways to reduce the process, and installing scrap cutters on the drawing die is one of them. Some workpieces have complex profiles, large drop, and are difficult to form. It may be difficult to form directly with the whole sheet. In the technological design of sheet metal stamping parts, it is possible to consider chamfering on the drawing scrap, which can not only ensure drawing forming, reduce a pair of molds, but also improve the economy.

(2) Reasonable design of stamping process. Reasonably design the process of sheet metal stamping parts to achieve the best structure and the least process. For example, after the process of sheet metal stamping parts is reasonably split, the development cost of two pairs of molds is reduced. In terms of production, after the reduction of two pairs of molds, the production efficiency is greatly improved, and it can achieve twice the result with half the effort.

(3) Reasonable selection of mold materials. The selection of mold materials should adhere to the principle of low price under the premise of ensuring use. In terms of material selection, it is not that the more expensive the material, the better. If the material grade is too high, it generally means the higher the price, the higher the price of the mold, the higher the development cost of the new car, and it is also related to how to reasonably determine the guiding principle of stamping production. The requirement of service life directly affects the structural design and material selection of the mold.

(4) Try to realize the production of left and right pieces in the same mold. The use of the production method of automotive sheet metal stamping parts is not only more conducive to the forming of materials, but also can save more materials than single-piece production.
