With the improvement of automobile safety, comfort and environmental protection requirements, intelligent automobile has become the general trend of the development of the automobile industry. How to improve the safety and comfort of the automobile through electronic technology has also become the hot spot of the whole industry. According to the prediction of the industry research institute, with the maturity of 4G / LTE and cloud technology, the global automotive electronics industry will break out this year, with an annual increase of 7% to 205 billion US dollars, which will maintain an average growth rate of 8.5% until 2020. At present, most of the core technologies of automotive electronics are in the hands of international component giants. Automotive electronics has become a weak link in China's automobile industry. Due to the difficulty in development and high requirements for product quality stability, most of the domestic market is occupied by foreign investors. Independent brands only occupy a place in the low-end markets such as vehicle navigation and video broadcasting.

What kind of large and medium-sized mechanical equipment must be used in automobile sheet metal processing? With the following equipment, the foundation can open small and medium-sized sheet metal processing plant.

In the process of producing automobile stamping parts, it is easy to affect the service life of the die due to the raw materials, heat treatment of die materials, structure, use specification and maintenance frequency, thus affecting the quality of stamping products.

China's auto parts industry started late, and it is difficult to meet the direct matching standards of domestic joint venture vehicle manufacturers in the key automotive parts manufacturing field.

It's very important to buy auto parts. Just like we choose the right medicine for ourselves, we can't be careless, otherwise, the consequences will be unimaginable. Therefore, automobile parts manufacturers remind us of the following points:

The brake pad is a key safety part in the brake system of automobile. The brake pad plays a decisive role in all braking effects. The brake pad is generally composed of steel plate, adhesive insulation layer and friction block, and the heat insulation layer is composed of non heat transfer materials for heat insulation. The friction block is composed of friction material and adhesive. When braking, it is squeezed on the brake disc or brake drum to produce friction, so as to achieve the purpose of vehicle deceleration and braking.

Car maintenance and car repair are closely related. There is maintenance in repair and repair in maintenance. In the process of vehicle maintenance, it may be found that a certain part or part is about to break out or damage, so we can take advantage of the maintenance opportunity to repair it. In the process of repairing, it is natural to maintain some parts that are not damaged. So, how do we maintain our cars in our daily life?

There is no need to say much about the cracking of automobile stamping parts. It is obvious that necking is difficult to detect. First of all, understand the mechanism of material deformation. The process of material tensile plastic deformation is mainly composed of three stages: uniform elongation stage, local elongation stage and cracking stage. Uniform elongation stage is the ideal stage, with material length direction, uniform thinning in thickness direction and surface The quality of the material is good, smooth, and the original roughness of the material has no obvious change, which is almost invisible to the naked eye. In the local elongation stage, the material is basically close to the elongation limit, and the purpose of elongation is mainly achieved through local severe and rapid deformation.

It is also one of the commonly used methods of concave shaping to pull out the concave by using a pulling device. The pulling device includes a suction cup, a pulling cylinder and a special puller. There is a suction cup at the end of the pneumatic concave puller to produce vacuum, and the force exerted by the inertia hammer will pull the metal depression back to the original shape. The screw at one end of the pull rod puller is screwed into the hole drilled in advance at the concave part. Holding the handle direction with one hand, the depression can be eliminated by pulling repeatedly, and then the through-hole is blocked with packing. In order to avoid the inconvenience caused by drilling, the pin can also be used to replace the screw in the concave spot welding, and then the tool is used to cut the solder joint after pulling out, so as to maintain the integrity of the metal surface.

In the automobile sheet metal parts processing industry, the use of lubricating oil is very important, because the proper lubrication of the machine can make it use for a longer time. During the production period, lubricating oil can help better production. However, it is necessary to pay attention to the use method and lubrication method of lubricating oil, because improper use will not play a role and may have the opposite effect Let's give you the following three examples of lubricating oil.

The raw material of automobile sheet metal parts processing and manufacturing process is the output of rolling process. Generally, sheet metal is sold as flat rectangular sheet of standard size. If the sheet is very long, it may be rolled. Therefore, the start of any sheet metal process is to cut the right shape and choose blank from the larger worksheet.

Automotive stamping parts should have good optimization design methods, so stamping manufacturers take stamping optimization design as an important way to reduce the cost of automobile manufacturing, which can make the automobile appearance beautiful. The reduction of air resistance can reduce the number of stamping parts and solder joints, which can effectively reduce the cost.

Precision automobile sheet metal parts are the basic process equipment to realize sheet metal processing. The surface quality, precision sheet metal dimensional accuracy, productivity and economic benefits of sheet metal stamping parts all depend on the reasonable design and manufacture of stamping die structure. Therefore, at present, the design and manufacture of stamping die are developing in the following three directions.

China's auto parts industry started late, and it is difficult to meet the direct matching standards of domestic joint venture vehicle manufacturers in the key automotive parts manufacturing field. Multinational auto parts suppliers play a leading role in China's key auto parts manufacturing field by virtue of their advanced parts design and R & D technology, long-term and stable cooperative relationship with vehicle manufacturers, or they are derived from foreign vehicle brands.

It is believed that many car owners have encountered such problems. When they get up and drive in the morning, they find that the parts on the car are missing, which is a very helpless thing. Even if the vehicle has an anti-theft device and is equipped with a ground lock, it can not prevent the loss of auto parts. Which parts of the car are easy to be stolen?

Use a single process die to punch some simple auto parts. When parts with complex shape are punched by multi-step stamping process, and the die structure or strength is limited, its inner and outer contour should be divided into several parts. For the workpiece with high flatness requirement, one leveling operation can be added after blanking process.

The process design of precision sheet metal mainly includes two aspects: process analysis of blanking parts and determination of blanking process scheme. With good processability and reasonable process scheme, the high quality crystal can be obtained stably with small material consumption, less process quantity and working hours. The die structure is simple and the die life is high. Therefore, the labor and blanking cost can be reduced.

After the car sheet metal parts are taken for repair or repair, the next process is very important, that is, cleaning, do a good job of cleaning, and the car body is completely new. So how to clean it?
