In the manufacturing process of auto parts, forging is widely used. Forging is divided into free forging and solid model forging. Free forging is a processing method in which metal blanks are placed on an anvil to withstand impact or pressure and form them (commonly known as "strike iron"). The blanks of gears and shafts of automobiles are processed by free forging. The solid model forging of auto parts processing is a processing method in which the metal blank is placed in the cavity of the forging die and subjected to impact or pressure. Mock-up forging is a bit like the process in which dough is pressed into a cookie shape in a mold. Compared with free forging, the steel parts manufactured by die forging have more complex shapes and more precise dimensions. Typical examples of die forgings processed for auto parts are: engine connecting rods and crankshafts, automobile front axles, steering knuckles, etc.

In the field of automobiles, such equipment as automobile stamping parts can be seen everywhere. Among the materials used in medium and heavy-duty automobiles, in addition to the covering parts or body panels used in these automobiles, there are also some load-bearing parts or supporting parts that use this kind of equipment. kind of material. Among them, large car parts such as frame and compartment that many people are familiar with belong to this field.

Other methods of using cold stamping can process some materials with relatively hard raw materials. Among them, steel plates and steel strips that are commonly used in the automotive field can be processed with this equipment. Nowadays, when making automobile stamping parts, less and less steel is used. 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. The weight of the car plays a very important role in reducing the consumption of gasoline and diesel during driving. And after using this new type of composite material, the maintenance work of the car body is also easier.

In addition, when using this cold stamping technology to manufacture automobile stamping parts, the quality of the product must be strictly dealt with. If when using this technology to make stamping parts, the production is not carried out according to the requirements, and the workmanship in the production does not meet the standards, the stamping parts produced in this way are likely to be unqualified in some aspects, and the service life may be shortened in use , And it is also easy to make the car in danger during travel, and damage the property or body loss of the occupants in the car. Other hypothetical production of substandard products may cause unnecessary waste of human resources.
