In the process of normal driving, there are many variable factors, which seriously affect the performance of the car, and are not conducive to ensure the normal driving of the car. Moreover, under the influence of climate change of terrain and temperature, it will also affect the normal driving of cars, which seriously threatens the safe travel of cars.

The production cost of automobile stamping parts includes fixed cost and variable cost. Fixed cost refers to the cost of equipment and die needed to produce stamping parts, while variable cost refers to material cost and labor cost. The proportion of fixed cost and variable cost is 35% ~ 65% respectively. In the fixed cost, it is mainly fixed investment such as tooling and equipment, which is less decomposed into unit cost; In the variable cost, the proportion of material cost is more than half. Therefore, in order to reduce the production cost of stamping parts, the material cost should be controlled strictly.

The body structure and material of automobile have changed a lot, and the application of load-bearing body has been gradually promoted. Therefore, the requirements of body repair technology are getting higher and higher. The repair process of automobile sheet metal parts not only requires the recovery of the shape of the automobile body, but also ensures that the performance of the repaired body is close to the state before the automobile damage, so as to avoid the occurrence of secondary accidents.

See if the joint is smooth. During the transportation and storage of spare parts, due to vibration and collision, burr, indentation, damage or crack often occur at the joint, which affects the use of parts. Pay attention to the inspection when purchasing.

Automobile sheet metal parts should have good optimization design methods. Therefore, stamping manufacturers take stamping optimization design as an important way to reduce the cost of automobile manufacturing, which can make the car appearance beautiful. The air resistance is reduced, and the number of stamping parts and welding joints can be reduced, and the cost can be effectively reduced.

In the long-term use of stamping dies for automobile stamping parts, wear or loose parts will also lead to product scrap. There are many stamping plants, after the installation of the mold for production, do not carry out the daily inspection and maintenance of the mold, only when the burr is relatively large, just remove the mold and simply grind the knife edge. As everyone knows, the wear of the mold is not only the knife edge wear, but also some mold accessories will wear with the use. After the wear of these accessories, it will have an impact on the accuracy of the whole mold.

According to the actual situation of the site, through the inspection of the tearing position, fracture morphology and extrusion degree of the parts, it is considered that the tearing and skewing behavior of the parts is mainly reflected in the flanging forming process, and the causes of this process are as follows

From the development of domestic auto parts enterprises, the overall level is still at a lower level, many production enterprises, but more scattered, large and small parts manufacturers are all over the country, but the large-scale is very few. Because of the dispersion of manufacturers, the competitive advantage of enterprises is not prominent, the data accumulation is small, and the R & D capacity is also general, which can not meet the large-scale demand of foreign investors.

The machining process of automobile sheet metal parts mainly includes the process of NC programming blanking, bending, pressing riveting, welding, spraying and packaging. The process of sheet metal processing is the combination of theory and practice, and it is the process of combining basic technology knowledge, basic process method and basic process practice of mechanical manufacturing.

If there is a problem in the programming procedure of automobile sheet metal parts, it will cause irreparable loss. Because the function of the special-shaped part of this kind of door plate is to install the door suction, the following processing schemes are usually adopted when mass production of such door panels: cutting machine cutting (three door suction pieces and other blanking) → punching internal holes of punch → angle cutting → folding machine folding test → welding four corners and three door suction pieces. The improvement of the scheme not only saves the cost of raw materials and equipment maintenance, but also greatly reduces the error rate of programming.

After the car body is damaged due to traffic accident and other reasons, the sheet metal parts of its shell will generally appear concave deformation. When the car body is slightly deformed, the general repair measures are to weld the concave parts of the car, pull the retractable ring device, pull the concave parts flat by traction,

In the automotive stamping industry, stamping is sometimes called sheet metal forming, but it is slightly different. The so-called sheet forming refers to the use of sheet, thin-walled tube, thin-walled material as raw materials for CNC machining plastic processing forming method, collectively known as sheet forming, at this time, the deformation of thick plate direction generally causes the causes of hardware damage and preventive measures.

The output and sales volume of auto parts industry will maintain a high-speed growth level in recent years. However, due to the continuous expansion of auto parts enterprises and the slow growth of auto demand, the overall production and sales rate of auto parts industry will decline, with a slight overcapacity, especially for products with low added value.

There are usually three steps for car body and spray painting First primer: it can fill the sand mark and micropore of the bottom layer of the workpiece, increase the adhesion of the lower layer coating, and also have the function of defect indication.

Mold is an essential process equipment in stamping process, which plays an important role in product quality, product life extension and production efficiency. It is difficult to meet the production demand because the die often loses its working size due to wear in the production process. Therefore, it is very important to improve the durability of the mold.

In order to prolong the service life of stamping parts and avoid corrosion and rusting, the corresponding anti-corrosion treatment is generally done Preheating the workpiece before spraying can improve the adhesion of asphalt paint and accelerate the drying. Cement mortar lining with special coating can improve the anti-corrosion ability of workpiece lining.

Automobile sheet metal part is a kind of technology to repair the damaged automobile body. Sheet metal repair is to repair the large and small damage caused by automobile collision. It is different from the traditional white iron worker and cold working sheet metal worker, and plays an important role in the whole process of automobile repair. The recovery degree of body collision damage will directly affect the use performance and safety structure of the car after repair. Our automobile sheet metal repair workers have to do the specific work is mainly aimed at the car in the unfortunate traffic accident, after the collision damage, the affected parts have different degrees of damage, the body structure and theoretical parameters always have different degrees of change and damage repair.

In recent years, with the rapid development of automobile industry, the global car ownership has risen sharply. With the energy crisis and environmental pollution becoming more and more serious, reducing energy consumption has become a serious challenge for the development of automobile industry. Vehicle lightweight is undoubtedly one of the important methods to solve the above problems.
