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.

In precision sheet metal processing, the process of shearing is similar to that of using scissors to cut a piece of paper. However, the machines used are somewhat different. There are two typical machines for cutting metal plates. One is the shearing machine, which has a long blade for cutting straight lines; it is used to cut long pieces of metal into smaller pieces. This operation is similar to that of a paper-cut machine: the sheet metal is held at the top of the hardening die, and the cutting blade cuts downward, usually driven by an electric or hydraulic punch.

Another sheet metal punch - cutting tool is a punch, a piece of hard tool steel, which is punched to cut a hole in the plate. Punch is a turret punch - turntable is a rotating turret, can accommodate dozens of different shapes and sizes of dies, typical shapes are rectangular and circular. Through a series of stamping, long grooves can be cut out. A typical punching operation is similar to the punching operation of perforated paper that you may have used to punch to clamp paper in a three ring binder.

Automotive sheet metal stamping parts have a very important position in the car industry, so in the production of this stamping parts, the use of raw materials is also very wide. Generally in the production of this stamping parts, most of the cold stamping process to produce or process. Because in the production of enterprises using cold stamping processing method, can meet the industrial product variety, the unit time to produce a large number of products. Especially in the era of large-scale mechanized production, the cold stamping processing method has been widely welcomed in large and small processing enterprises.

In the field of automobile, automobile stamping parts can be seen everywhere. In addition to the covering parts or body panels used in these cars, there are also some load-bearing parts or support parts that use this material. During this period, many people know about the frame, carriage and other large-scale auto parts belong to this field.

In the cost of automobile stamping parts, the material cost is about 60%. Therefore, the economic utilization of materials is of great significance. Layout refers to the layout of parts on the strip or plate.
