A large number of cold stamping processes have been used in the production of automotive stamping parts, which are suitable for the needs of many varieties and large-scale production of automotive stamping parts industry. In medium and heavy-duty vehicles, most of the covering parts, such as body outer panel, and some load-bearing and supporting parts, such as frame, carriage and other auto parts are automobile stamping parts. Rongzhi automobile stamping parts show that the steel used for cold stamping is mainly steel plate and steel strip, accounting for 72.6% of the steel consumption of the whole vehicle. The relationship between cold stamping materials and the production of automobile stamping parts is very close. The quality of materials not only determines the performance of products, but also directly affects the process design of automobile stamping parts and the quality, cost, service life and production organization of products It is an important and complicated work to select materials reasonably.

For those who don't know the industry of inspection tools, they don't know much about the use of inspection tools. During the use of inspection tools, the stamping parts of automobiles remind the users of inspection tools to pay attention to some requirements in order to avoid errors or tool damage.

1 before use, check whether it is within the validity period of verification. The measuring surface of the inspection tool and the measured parts of the parts shall be wiped clean to avoid the existence of stolen goods affecting the measurement accuracy.

2. During the use of inspection tools, do not stack them together with tools, knives, etc. to avoid bumping the inspection tools, and do not place them on the equipment casually, so as to avoid falling of inspection tools due to equipment vibration.

3. The inspection tool is a measuring tool and can never be used as a substitute for other tools.

4. In case of any abnormal phenomenon, such as uneven surface, burr, bending deformation, etc., do not repair by yourself, and do not use hammer, file, gauze, etc.

5. Due to the possible shape error of the parts, the inspection of a workpiece must be carried out in different parts of the workpiece for many times to determine whether the workpiece is qualified. It is not allowed to use excessive force and hard plug.

6. Label of measurement certificate on the protection inspection tool.
