In the industrial field, different production processes will have a great impact on the performance of products. So, for stainless steel stamping processing, what are its processing characteristics and advantages? Next, automobile stamping parts manufacturers will analyze and answer this question, hoping to help you. First of all, for automobile parts processing, we need to choose different processing technologies according to different materials. If we want to process stainless steel stamping parts, we must reduce the loss of materials as much as possible to keep the original material properties. Only in the process of processing, the shape has been changed to make it meet our needs and meet the requirements of production standards.

1Check whether the trademark identification is complete. The quality of the original product's outer packing is good, the writing on the packing box is clear, and the overprint color is bright. The packing box and bag shall be marked with the product name, specification, model, quantity, registered trademark, factory name, address and telephone number, etc. some manufacturers shall also mark their own marks on the accessories. Some important parts such as generator, distributor, fuel injection pump, etc. are also equipped with operation manual, certificate of conformity and inspector's seal to guide the user to use and maintain correctly. When purchasing, you should carefully recognize it to prevent buying fake and inferior products.

The materials used in automobile stamping parts are closely related to metal stamping parts. The nature of metal stamping materials directly affects the quality and service life of metal stamping parts, and may also affect the production cost. What are the basic requirements of metal stamping on materials?

The process design of precision sheet metal mainly includes the process analysis of blanking parts and the determination of blanking process plan. With good processability and reasonable process plan, we can use small material consumption, less working procedure quantity and working hours to obtain high-quality crystalline products that meet the requirements stably, and make the die structure simple and die life high, so we can reduce labor and blanking cost.

It is an effective and useful method to adjust and control the deformation resistance by setting Drawbead on the pressing surface. The drawbead can adjust the flow of material well, make the flow resistance of each part of the material in the drawing process even, make the amount of material flowing into the cavity fit for the needs of the workpiece, and prevent the phenomenon of more wrinkling and less cracking.

The automobile stamping die represents the generalization that can be classified into the basic figure. First, search whether there is a stamping die that is completely common with the generalization and can be rushed out with a stamping action in the stamping die library. If there is such a die, the stamping die set under "select stamping die" will be neglected, and the searched stamping die will be directly used.

For automotive stamping parts, because they are website products and keywords, so in terms of learning requirements, they should be comprehensive and specific. Therefore, the knowledge content and related difficult problems are all involved, and none of them can be omitted. So, based on this, we will start to do it immediately to improve your learning efficiency.

If the stamping process of automobile parts is hot stamping, the benefits it can bring are mainly to realize the lightweight production of automobile, and to effectively improve the strength of stamping parts. Moreover, it is formed at high temperature, so it also has the advantages of high accuracy, good molding performance, and no rebound problem. The automobile parts that can be used are anti-collision beam, safety parts and body structure parts.

Stainless steel automobile sheet metal parts are generally the general term of stainless steel sheet metal parts and acid resistant steel. Stainless steel sheet metal parts refer to the steel resistant to weak medium corrosion such as atmosphere, steam and water, while acid resistant steel refers to the steel resistant to chemical corrosive medium corrosion such as acid, alkali and salt. Stainless steel sheet metal parts come out at the beginning of this century, and have a history of more than 90 years.

There are many sheet metal materials suitable for automotive stamping parts processing, which are widely used in the electronic and electrical industry, including: 1. Ordinary cold rolled sheet SPCC. SPCC refers to the continuous rolling of steel ingot into steel plate coil or sheet of required thickness by cold rolling mill. SPCC surface does not have any protection, so it is easy to be oxidized when exposed to the air, especially in the humid environment, the oxidation speed is accelerated, dark red rust appears, and the surface should be painted, electroplated or other protection during use.

The fitting degree of sheet metal parts during loading is also a key point to distinguish the quality of sheet metal parts. It will determine whether the final effect of loading is beautiful or not, and at the same time determine the difficulty of installation. Therefore, it is also a factor that many sheet metal maintenance technicians are very concerned about. If the fitting degree of sheet metal parts and the original car is low, such as the hole position cannot be aligned, the error of loading clearance and flatness is too large (the one-way tolerance of high-quality sheet metal parts in this respect should be controlled below 1.0mm), it can be basically judged that this is a non-conforming product from a small factory. Mr. Luo said that few car owners have noticed that a strong collision will cause slight deformation of the whole car body. At this time, if you install the sheet metal parts with large clearance, it will cause the car body to deform again, affecting the recovery of the damaged vehicle to its original appearance and quality.

There are two kinds of surface treatment methods commonly used in the processing of automobile sheet metal parts: electroplating and spraying. Electroplating is divided into galvanizing, nickel plating, chromium plating, etc. the main purpose is to form a protective layer of metal or alloy on the surface of sheet metal workpiece by using the principle of electrolysis, which plays a role of protection and decoration. Spray can be divided into spray painting and powder spraying. After the material parts are pretreated, the spray gun gas is used to disperse the coating into uniform and fine droplets, which are sprayed on the surface of the body work piece to form the coating on the surface of the work piece, and then heated and dried. Spraying can protect the workpiece. In addition to the above two methods, there are some other surface treatment methods, such as anodizing, chromate, wire drawing, sandblasting and oxidation.
