Advantages and Types of Metal Punching Process

Stamped parts are parts obtained by stamping process methods with certain shapes, sizes, and properties. Stamped parts are widely used in fields such as aviation, automobiles, ships, machinery, and chemical engineering, and have gradually become an important part of the current parts manufacturing industry. Applying computer-aided design and manufacturing technology to the stamping parts manufacturing industry can make the design of stamped parts very fast, and the manufacturing and assembly efficiency can be significantly improved. Precision metal punching process is a widely used metal processing technology, which is widely used in various fields of precision products. What are the characteristics of metal punching process?

The advantages of metal punching process

• The mold ensures the dimensional and shape accuracy of precision metal stamping parts. Generally speaking, the surface quality of stamped parts will not be damaged, and the service life of the mold will be longer, so the quality of precision metal stamped parts is stable.

• Precision metal stamped parts can process parts of various sizes and complex shapes, such as small second hands of clocks, automobile beams and covers, as well as the cold deformation and hardening effect of materials in the metal stamping process. The strength and rigidity of metal stamped parts are high.

• The production efficiency of metal stamped parts is high, easy to operate, and easy to realize mechanization and automation. This is because metal punching process depends on molds and stamping equipment to complete processing. The stroke time of ordinary press can reach several dozen times per minute, and the stroke of high-speed press can reach several hundred times or even thousands of times per minute, and each stamping stroke can punch holes.

• Metal stamped parts usually do not produce chips and waste, consume less materials, and do not need other heating equipment. Therefore, this is a processing method that saves materials and energy, and the cost of metal stamped parts is low.

The types of metal punching process

Custom metal punching process is divided into two categories according to the deformation mode of materials: forming process and separation process.

• Separation process is to separate the sheet metal according to a certain contour line to obtain stamped parts with certain shapes, sizes, and cutting surfaces. Separation process includes: blanking, punching, cutting, trimming, etc.

• Forming process is to produce stamped parts with certain shapes and sizes by plastic deformation of the material without breaking. The forming process includes: drawing, flanging, forming, perforation, bending, etc.
