Stamping is at the top of the four major processes in automobile manufacturing. Stamping is used as the basis for the quality assurance of automobile bodies. Its quality is directly related to the pros and cons of the entire vehicle. The quality inspection methods are:
1, material inspection
The quality control of materials is divided into material receiving inspection, material cleaning before and after inspection, and material production inspection. The purpose is to confirm that the material quality meets the production requirements.
2, first article 1 sequence inspection
The first part of the stamping part determines the quality of the entire batch, and the inspection of the first part and the first part is an important part of the first part inspection. In a specific way, observe whether there are any bad phenomena such as bottom marking, cracking, wrinkling, and deformation of the part.
3.Online partition check
100% inspection of stamping parts is mainly realized by zone inspection, including visual inspection and tools.
4. First, middleware and tailpiece extraction inspection
Using the first, middleware, and tail extraction inspections can better achieve quality control.
5.Inspection of the whole basket of parts
Confirm the quality of the whole basket after the basket is installed, which can prevent the outflow of the bad parts caused by the unsuitable use of personnel in the basket and the station equipment.
6. Detection of thinning rate of workpiece sheet
Using a plate thickness tester to detect the thinning rate of the easily cracked parts of the workpiece analyzed by CAE and the statistically cracked parts of the workpiece during production, it can warn the dangerous parts of the workpiece that are easy to crack in advance.
7. Precision inspection
Using tools to carry out full-size accuracy testing on the part (the first part), it is possible to pre-warn the part with a large change in the pass rate in advance to avoid affecting the dimensional accuracy of the entire vehicle.
8. Hand repair of defective products
Defective hand repair refers to the whole basket and secondary selection inspection of the parts after the parts are repaired. The purpose is to repair the defects detected in each quality control project, avoid the outflow of defective products and reduce the loss of scrap.
9.Second selection inspection of parts
The second selective inspection after the production of the easily cracked parts can avoid the outflow of defective products due to the failure to detect the previous inspections.
10. Inspection of parts out of stock
This is the last pass of the quality control of the product. Through the re-confirmation of the outbound inspection, the outflow of defective products can be effectively avoided.
A variety of quality inspection methods can be summarized into pre-production control, in-production control, and post-production control, which can achieve the three goals of "no acceptance of defective products, no manufacturing of defective products, and no outflow of defective products".
