In order to distinguish the quality of sheet metal parts, we can start with packaging, weight, welding process, painting process and the degree of coincidence when loading. It is very difficult for ordinary car owners to distinguish whether the sheet metal parts are of high quality after handing in the car, so they can distinguish them from the packaging of the products in advance: the products produced by small factories will not print the contact method and factory address, while the regular manufacturers will have steel stamps, qualifications and inspection labels on the products in addition to the contact method and factory address, even if consumers will use them in the future. Now, there is also a way to safeguard rights.

Accidental trauma repair is the main method to repair the impact damage of automobile stamping parts. The usual methods are shrinkage shaping, fold unfolding, stretching and pad prying reduction.

The quality inspection of automotive stamping parts needs to achieve: smooth surface, clear edges, enough rigidity and dimensional stability, and can not have wrinkles, scratches, brushing and other defects.

It is the aspiration of many car owners to repair cars without asking for help. Because only their true love of their car, will not be some black car repair black hands. There are some commonly used automotive parts on the car, which requires the owner to have certain maintenance skills, so as to avoid sudden incidents, can calmly respond.

See if the logo is complete. The packaging quality of authentic products is good, the handwriting on the packaging box is clear, and the overprint color is bright. Packaging boxes and bags should be marked with product names, specifications, models, quantities, registered trademarks, factory names, factory addresses and telephone numbers, etc. Some manufacturers also make their own markings on accessories. Some important components, such as generators, distributors, fuel injection pumps, are also equipped with instructions, certificates and inspector's stamps to guide users to use and maintain correctly. When choosing and purchasing, it should be carefully recognized in order to prevent the purchase of counterfeit and inferior products.

The automobile factory has 4 night processes (4 night workshops) farewell is stamping workshop, welding workshop, painting workshop, general disassembly workshop. The automobile stamping parts die in the stamping workshop. To give you an example, all the metal shells you see in automobile shells belong to stamping parts. Basically, the steel plate is operated as a designed die and pressed into the required medium shape by a presser (tonnage to 2000 tonnage) according to the designed process.

he application scope of metal stamping parts: Special stamping enterprises. For example, stamping of aviation parts belongs to this kind of enterprise, but these craft factories also belong to some large factories.

Oiling inspection of metal stamping parts: Clean the surface of the outer covering with clean gauze. Then use a clean brush to uniformly apply oil in the same direction to the entire outer surface of the stamping part.

Causes of Die Loss in Stamping The material selection of the main working parts of the die is inappropriate. Material performance is not good, wear-resistant; die steel is not refined, with a large number of smelting defects; convex and concave die, forging process is not perfect, there are hidden dangers of heat treatment.

Touch test: wipe the surface of the outer covering with clean gauze. Inspectors need to wear touch gloves to touch along the surface of automotive stamping parts vertically. This inspection method depends on the experience of inspectors. If necessary, the suspicious area can be polished and verified by oil stone, but this method is an effective and rapid inspection method.

Stamping parts are often used in daily life, such as instruments, household appliances, bicycles, office machinery, household utensils and many other products are stamping parts. Then how to reasonably formulate stamping parts processing technology?

In recent years, with the improvement of people's living standards, the demand for automobiles is also growing. The competition among automobile factories is becoming increasingly fierce. New models with cost competitiveness are continuously invested to seize the market. At the same time, the natural resources such as iron ore and coke used to produce automobile steel are becoming increasingly tense. Improving the material utilization ratio can not only reduce the manufacturing cost of automobiles and improve the competitiveness of automobile brands, but also conform to the environmental protection concept of energy saving and consumption reduction.

When trimming the die of automotive stamping parts, there is often a headache problem, that is the phenomenon of iron chip dropping. Especially around the die scrap knife, this situation will be more obvious. This will have a great negative impact on the quality and appearance of stamping products, so we need to deal with it in time.

First of all, the automobile stamping parts designed must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. When permitted, stamping parts can be made of low-cost materials, so that parts can be blanked as much as possible without waste and with less waste.
