Forging is widely used in the processing and manufacturing of auto parts. Forging is divided into free forging and solid model forging. Free forging is a processing method in which a metal blank is placed on an anvil to bear impact or pressure (it is called "forging" in the market). The blanks of automobile gears and shafts are processed by free forging. Solid model forging of automobile parts processing is a processing method in which the metal blank is placed in the die bore of the forging die and formed under impact or pressure. Solid model forging is a bit like the process in which dough is pressed into the shape of biscuits in the mold. Compared with free forging, the shape of steel parts manufactured by die forging is more complex and the overall dimension is more accurate. Typical examples of die forgings for automobile parts processing are: engine connecting rod and crankshaft, automobile front axle, steering knuckle, etc.
In the field of cars, the equipment of car stamping parts can be seen everywhere. Among the materials used in medium and heavy cars, in addition to the cover parts or body panels used in these cars, some load-bearing parts or supports use this material. During this period, the frame, carriage and other large car parts that many people know belong to this field.
Other cold stamping methods can be used to process some hard materials. During this period, the steel plate and steel strip often used in the field of cars can be processed with this equipment. At present, less and less steel is used in the production of car stamping parts. On the one hand, some raw materials composed of aluminum and carbon elements have stronger hardness, and the use of this composite material can effectively reduce the weight of the car itself. It has a very important effect on the less consumption of gasoline and diesel during the travel of the car. Moreover, after using this new composite material, the protection of car body is also simpler.
When using this cold stamping technology to make car stamping parts, the quality of products must be dealt with severely. It is assumed that when using this technology to make stamping parts, they are not produced according to the requirements, and the workmanship in the production does not meet the standards. In this way, the stamping parts produced are likely to be unqualified in some aspects, which may shorten the service life in the application, and simply make the car dangerous in the process of travel, hurt the industry of passengers in the car, or lose their body. Other assumptions are that producing substandard products can cause unnecessary waste to human resources.
