Automobile stamping parts on automobile body are generally divided into covering parts, beam frame parts and general stamping parts. The stamping parts that can clearly represent the image characteristics of the automobile are automobile cover parts. Therefore, the more specific automobile die can be said to be "automobile panel stamping die". It is short for automobile panel die. For example, front door outer panel trimming die, front door inner panel punching die, etc.

Generally, according to the use of automobile stamping parts, it can be divided into covering parts, supporting parts, structural reinforcement parts, supports, frame beams, etc. Covering parts are divided into outer covering parts and inner covering parts, which have the characteristics of thin material, complex shape, large structure size and high precision, high surface quality, and can not be formed in one time. Many beam supports are included in the inner panel assembly. Such as the strengthening beam of automobile engine, cab, floor, side wall, etc

General stamping parts, compared with covering parts, are simple in shape, small in structure size, small in deformation degree, low in size accuracy, few in process, simple in mold and small in tonnage of equipment. No need to form a production line, single machine can be completed

As a manufacturer of stamping parts welding and manufacturing, we will introduce stamping technology to you. First, we need to popularize a knowledge of what is stamping:

Stamping is an efficient production method. By using compound die, especially multi position progressive die, multiple stamping processes can be completed on a press, realizing the full-automatic production from uncoiling, leveling, blanking to forming and finishing.

Stamping is mainly classified by process, which can be divided into separation process and forming process. The purpose of the separation process is to separate the stamping parts from the sheet along a certain contour line and ensure the quality requirements of the separation section. The purpose of forming process is to make the sheet metal plastic deformation without breaking the blank, and to make the required shape and size of the workpiece. In actual production, it is often a variety of processes applied to a workpiece. Punching, bending, shearing, drawing, bulging, spinning and straightening are the main stamping processes.

The surface and internal properties of sheet metal for stamping have a great influence on the quality of stamping products, which requires that the thickness of stamping materials is accurate and uniform; the surface is smooth without spots, scars, scratches, surface cracks, etc.; the yield strength is uniform without obvious directionality; the uniform elongation is high; the yield ratio is low; the work hardening is low.
