Stainless steel automotive sheet metal parts are generally the general term for stainless steel sheet metal parts and acid-resistant steel. Stainless steel sheet metal parts refer to steel that is resistant to corrosion by weak media such as atmosphere, steam, and water, while acid-resistant steel refers to steel that is resistant to corrosion by chemically corrosive media such as acids, alkali, and salts. Stainless steel sheet metal parts have been around since the beginning of this century and have a history of more than 90 years.

Bending molds are made of high-quality steel with special heat treatment. They have the characteristics of high hardness, not easy to wear, and can withstand high pressure. However, each set of molds has its own ultimate pressure: tons/meter, so you must be correct when using the molds. Select the length of the mold, that is, how much pressure to add per meter, and it must not exceed the pressure marked on the mold.

Automobile sheet metal parts are a processing method for automobile maintenance, also called cold work. To put it bluntly, if the appearance of the car body is damaged and deformed, the sheet metal process is required. Automobile collision repair has developed from the original "smashing, pulling and welding repair" to secondary body manufacturing and assembly. The repair of a vehicle in a collision accident is no longer a simple matter of banging on the sheet metal of the car. The quality of the repair cannot rely solely on observing the appearance and gaps of the vehicle with the naked eye.

The designed metal stamping parts must meet the product usage and technical performance, and be easy to assemble and repair.

The many outstanding advantages of stamping processing make it widely used in various industries such as machinery manufacturing, electronics, and electrical appliances. Most of them are processed by stamping methods, ranging from automobile covering parts to small clocks, instruments and instrument components. At present, stamping products obtained by cold stamping process occupy a very important position in modern automobiles, tractors, motors, electrical appliances, instruments, meters and various electronic products and in people's daily lives.

Parts drawings/inspection guidance (standard) book: Some simple hardware automotive stamping parts can be inspected by comparing the various dimensions marked in the drawings, followed by the use of various measuring instruments, basic tape measures, calipers, micrometers, tables, Stop rules and so on. Also pay attention to some important tolerances marked on the drawings and whether the tolerance range is consistent with the drawings. For some high-precision products, tolerance requirements must be strict.

Cars are a big consumer product for most families in my country, so everyone is very careful when choosing a suitable motor vehicle. In fact, there are many standards to refer to when choosing a motor vehicle. However, if we want to know from a simple aspect whether the motor vehicle in front of us meets our requirements, the quality of the entire vehicle is also good from the quality of automotive stamping parts. method.

Nowadays, when manufacturing stamped parts for automobiles, cold stamping is mostly used, and when manufacturing stamped parts, the die material must be debugged before it can be used in production. After years of research, engineers have formulated strict requirements for the debugging of cold stamping dies. After these detailed debugging, these cold stamping dies can exert more energy in the process of making stamping parts.

Automobile stamping parts play a very important role in the automobile industry, so when producing such stamping parts, a wide range of raw materials are used. Generally, when producing such stamping parts, cold stamping technology is mostly used for production or processing. Because the cold stamping processing method is used in production enterprises, it can meet the characteristics of a large variety of industrial products and a large number of products produced per unit time. Especially in the current era of mechanized mass production, cold stamping processing methods have been widely welcomed by both large and small processing companies.

Car stamping parts, taken out of context, are metal stamping parts that constitute car parts. Among automobile stamping parts, some are stamped directly to become automobile parts, while the other part needs to be processed by welding, machining, or painting after stamping before it can become automobile parts. There are many types of car stamping parts, such as car shock absorber stamping parts, spring trays, spring seats, spring brackets, end caps, sealing covers, compression valve covers, compression valve sleeves, oil seal seats, bottom covers, dust covers, impellers, oil Barrels, lugs, brackets, etc. are all automotive stamping parts.

Now with the continuous development of the automobile industry, the automobile stamping parts industry has been decomposed into many new branches, and the specific contents of these branches are still being refined. In this situation, the question of product specification in each category should arise.

Since many stamping factories belong to the main engine factory, the automotive stamping parts market is very imperfect and sound. But the small stamping parts market is very mature in some areas in the south. Judging from the current situation, my country's stamping parts market has the following problems:

There has always been a phenomenon in the after-sales service of automobiles in our country, that is, the same auto parts are much more expensive in 4s than in maintenance points or auto parts cities, and even several times higher.

Mold assembly is a job with relatively high technical requirements. It requires experienced operators to install according to technical specifications. It is often necessary to repeatedly disassemble, turn over, test, adjust, and open and close mold parts, which is labor-intensive. Especially those progressive dies with complex structures and large stamping dies require operators to debug for a long time. In order to improve the degree of mechanization of mold assembly, assembly accuracy, and reduce manual assembly procedures. Mold assembly machines have been widely used abroad.

When many users design new products or develop products, they often only pay attention to the development and development of products, or the price at the initial stage, and do not pay much attention to communication and exchanges with injection mold manufacturers. In fact, they are determining the preliminary design plan of the product. Finally, it is very necessary to communicate with the injection mold manufacturer in advance. Today, I will give you a specific introduction to the precautions for opening the injection mold.

1. Heat resistance With the emergence of high-speed molding machinery, the production speed of plastic products is accelerated. Since the molding temperature is generally between 160 and 350 °C, some of them have poor fluidity and fast forming speed, which will cause the molding surface temperature of the mold part to exceed 400 °C in a very short time. When the working temperature of the mold is high, the hardness and strength of the mold will decrease, resulting in early wear or plastic deformation of the mold and failure. In order to ensure the accuracy and small deformation of the mold during use, the mold steel should have high heat resistance. In order to reduce the temperature rise, the mold steel should have good thermal conductivity and low thermal expansion coefficient.

The use of stamping dies is indispensable for the production of stamping parts. The quality of products is largely determined by the precision of stamping dies, which shows the importance of stamping dies. Today, automotive stamping parts manufacturers want to introduce to you the knowledge about stamping dies, and the details are how to determine the blanking gap.

Automobile stamping dies represent the generalization that can be included in the basic graphics. First, go to the stamping die library to search whether there is a stamping die that is completely consistent with the generalization and can be punched out of the generalization with one stamping action. If there is such a die, the stamping die set under "Select Stamping Die" will be ignored, and the found stamping die will be used directly.

Among the many factors that affect the quality of automotive stamping parts, the influence of mold structure is very large. The forming effect of the deep-drawing part is directly affected by factors such as the radius of the die, the geometry of the work piece of the die, the way the die is guided, the setting of the drawing rib (groove), and the size of the air hole in the die.

Automobile stamping parts should have a good optimization design method, so stamping manufacturers regard stamping optimization design as an important way to reduce the cost of automobile manufacturing, which can make the appearance of automobiles beautiful. The reduction of air resistance can also reduce the number of stamping parts and solder joints, which can effectively reduce costs.
