Automobile stamping parts are mainly formed by stamping metal or non-metal sheet materials with the help of the pressure of the press through the stamping die. It mainly has the following characteristics:
- 1. During the stamping process, since the surface of the material is not damaged, it has better surface quality and a smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments.
- 2. Stamping parts are made by stamping under the premise of low material consumption. The parts are light in weight and good in rigidity. After the sheet is plastically deformed, the internal structure of the metal improves the strength of the stamping parts.
- 3. The metal stamping parts have high dimensional accuracy, the same size as the mold parts, and have good interchangeability. No further machining is required to meet general assembly and use requirements.
Manufacture of auto parts inspection tools:
The design of the inspection tool is discussed from the aspects of practicability, accuracy, manufacturability, technicality and economy, and the manufacturing needs to meet the realization of these five performances according to the design. For now, the production process of the inspection tool can be roughly expressed.
1. Inspection of finished products:
After the inspection tool is completed, the corresponding inspection is required to ensure its accuracy after being put into use. Usually, inspection can be divided into two types, one, dynamic acceptance. That is, according to the corresponding parts, the parts are used to verify their specific operability and performance. Second, static acceptance, through the measurement and comparison of design data and actual data to check whether it is accurate.
2. Responsibility in the following order:
The entire production process cannot be completed by a single producer. Therefore, in the process of casting, each worker needs to make his own production order rigorously. After the production, it is necessary to strictly check the correctness of this order. At the same time, it is also necessary to test the quality and correctness of the previous sequence. Once a problem is found, it needs to be put forward in time, and corresponding measures should be taken to remedy it.
3. The inspection tool is designed for the scheme:
Generally speaking, the designer and manufacturer of the inspection tool are not the same person, especially in the current social background, many designers have no practical experience, so their design is relatively ideal, in the process of design, ignoring the actual of production. Therefore, the author believes that before production, the production staff need to study the entire design, what kind of production should be used in different sequences, and whether it can be produced.
