Choosing the right process route for auto parts industry

China's auto parts industry started late, and it is difficult to meet the direct matching standards of domestic joint venture vehicle manufacturers in the key automotive parts manufacturing field.

Multinational auto parts suppliers play a leading role in China's key auto parts manufacturing field by virtue of their advanced parts design and R & D technology, long-term and stable cooperative relationship with vehicle manufacturers, or they are derived from foreign vehicle brands.

In this context, China's auto parts suppliers' approach to key parts design and manufacturing often starts from seeking cooperation with multinational auto parts suppliers. Through continuous technology accumulation, the gap between China's auto parts suppliers and multinational auto parts suppliers in the field of key parts manufacturing is narrowed, so as to achieve the goal of independent matching of key parts of vehicle.

Sheet metal parts have the characteristics of thin and easy forming, which can be formed into parts of various shapes. With the application of welding, assembly, riveting and other processes, it is possible to realize multi structure products. At the same time, these characteristics also make the sheet metal parts more or less deformed in the process of processing, such as bending deformation, torsion deformation, concave convex deformation and so on. These deformations make the size or shape of the whole component change, resulting in quality problems. However, the production process of sheet metal parts has its inherent law. For the same type of products, according to the existing equipment and manpower, the processing sequence can be flexibly adjusted and the reasonable processing technology can be given.

Therefore, choosing the right process route is an effective measure to prevent and solve this kind of problem. The formulation of process route must combine the shape of the product and the existing processing equipment of the company to meet the product quality requirements as the premise, and finally achieve the goal of economic benefits. The general process route of automobile stamping parts can follow the following principles: (1) meet the product quality requirements; (2) product process route is economical; (3) provide optimization for subsequent processes; (4) facilitate processing. The quality of the process personnel to consider the focus comes from the structure, functionality and appearance of the product, as well as the proficiency of the equipment processing ability. Considering the total error matching relationship of the whole machine, optimizing the product processing method to reduce the processing difficulty, and setting a relatively stable process route in batch production are the three directions to be considered in process planning.
