Generally speaking, the cracks in automobile stamping parts inspection (also known as cracks, the professional name should be necking), the cracking problem or rely mainly on visual detection and perception and prevention, which requires a certain amount of experience to accumulate:

Stamping parts become a kind of products that can not be ignored in production. From the aspect of stamping parts production, it should be noted that automobile stamping parts show that only after each part of the technical strength is guaranteed, people can give better adjustment in each part. I hope every friend can grasp it better in his life, so that he can coordinate all parts of production, let us have a better understanding of stamping production and know how to use it in the future.

Stamping production belongs to material forming technology. In recent years, it is a new method of metal cold deformation processing. It is one of the main methods of metal plastic processing. In the production of stamping parts, people use the power of conventional or special stamping equipment to stamp, use pressure to make the material deform, and then use the sheet metal deformation in the die to get product parts with a certain size and shape. What problems should we pay attention to in the production?

At present, there are fake and inferior products in almost all kinds of automotive accessories. Nearly one third of them have no origin or model, and their origin is unknown. There are also many parts that are re-rebuilt from scrap automotive materials. Therefore. Rongzhi automotive stamping parts have mastered some knowledge of identification of counterfeit and inferior automotive parts is very necessary.

It's said that it's easy to buy a car and it's difficult to keep a car. Especially in winter, when the weather is wet and rainy, the sheet metal parts of the car paint are more easily rusted. It's distressing and annoying to watch the rusty car. So, how to protect the paint surface and metal parts of the car to prevent rusting?

In the automobile sheet metal processing industry, the use of lubricating oil is very important, because proper lubricating oil can make the machine use longer, lubricating oil during production can help better production, but it should be noted that the use of lubricating oil and lubricating methods, because improper use not only will not play a role may play the opposite role. As a result, we will take the lubrication of automobiles as an example to show you three major misconceptions in the use of lubricants.

Stamping process is one of the processing methods to complete metal plastic forming. External forces are usually exerted on sheets, strips, pipes and profiles by press and die to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece.

Stamping is a method of forming and processing parts (stamping parts) with required shape and size by applying external force to sheet, strip, pipe and profile by press and die to produce plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure processing), which is called forging. Stamping blanks are mainly hot-rolled and cold-rolled steel sheets and strips.

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.

Whether the die used for metal stamping parts is elastic pressure unloading plate or fixed unloading plate depends on the unloading force, and material thickness is the main factor to be considered. With the increase of elastic force of elastic components used in die (e.g. rectangular spring), the unloading force of elastic discharging plate is greatly enhanced. Hardware stamping is a method of forming and processing parts (stamping parts) with required shape and size by applying external force to sheets, strips, pipes and profiles by press and die to produce plastic deformation or separation.

Automobile sheet metal is a comprehensive cold processing technology for sheet metal (usually less than 6mm), including shearing, punching/cutting/composite, folding, welding, riveting, splicing, forming (such as automobile body), etc. Its remarkable feature is that the thickness of the same part is the same. The products processed by sheet metal process are called sheet metal parts. Sheet metal parts in different industries are generally different, and they are often used as appellations when assembling.

Because the brake pads of automobile parts are consumables, the more driving kilometers, the worse the wear of the brake pads. When the wear reaches the critical point, it must be replaced.

In winter, a car-mounted electric heating cup is indispensable. In winter, unlike getting off the shelf, you can always choose a bottle of mineral water. When cold water is drunk, the stomach will suffer. Especially, the car owners who have stomach diseases need to pay more attention to it. The car parts electric cup lets you enjoy the steaming water at any time. The water you carry does not need to worry about what to do after cooling, but also lets you avoid it as far as possible. No fire, daily travel, but indispensable.

Why is the quality of domestic auto parts industry worrying? At present, domestic automobile parts suppliers generally adopt the "drawing processing" mode, that is, automobile manufacturers provide product data and drawings to suppliers, the latter manufacture according to drawings; in the same case, the difference should be in the use of materials and manufacturing process.

Generally speaking, we can judge from two aspects: body and surface panels. Next, let's say one by one, but there's one thing to note. Here's the method you can use as an ordinary car buyer to go to 4S shop. Because it doesn't involve special tools, it's not professional, but you can generally understand the quality of automobile sheet metal parts by virtue of them.

First of all, it is easy to neglect whether there are pockets on the surface of automobile sheet metal by hand, but it is also very important. After leaving the factory, the white body comes to the painting workshop through electrophoresis and other processes. At this time, the surface may have a small irregular bulge. In order to prevent it from affecting the spraying effect, the staff will do careful inspection and remove the defects with special tools. Of course, it may be because some of the judges'carelessness can not be found in time, then you need to touch it by yourself.

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.
