Precision forging technology and method


Precision forging forming technology is near net forming technology, which means that after the part is formed, it can be used as a forming technology of mechanical components with only a small amount of processing or no processing, that is, to produce workpiece blanks close to the shape of the parts.

Compared with the traditional forming technology, the subsequent cutting amount is reduced, the material, energy consumption and processing procedures are reduced, the production efficiency and product quality are significantly improved, the production cost is reduced, and the market competitiveness of the product is improved.

main application

1. Produce refined blanks, and finish precision die forgings to obtain finished parts.

2. To produce precision forged parts, precision forging the main part of the formed parts, eliminating the need for cutting, and some parts of the parts still need a small amount of cutting.

The development of precision forging

Precision forging technology has gone through fifty or sixty years of development, and a large number of high-quality, energy-saving and labor-saving precision forging technologies have emerged one after another, such as hot precision forging, warm precision forging, cold precision forging, cold-warm composite forming, compound forging, precision roll forging -Precision forging technologies such as die forging and composite forming have been developed rapidly, and are increasingly used in the production of automobile transmissions and engine gears abroad, and are widely used in the automobile industry.

With the development of the manufacturing industry, the application of precision forging technology has become more and more extensive, and the requirements for technology have become higher and higher. The main development directions are as follows:

1. Computer simulation technology of forging process

2. The forging process is developing towards automation and flexibility

3. Green forging forming technology

Precision forging forming technology (net forming) refers to a forming technology that meets the requirements of parts with only a small amount of processing or no processing. Precision forging technology is an important part of advanced manufacturing technology, and it is also a widely used parts manufacturing process in automobile, mining, energy, construction, aviation, aerospace, weapons and other industries. Precision forging technology not only saves materials, energy, and reduces processing procedures and equipment, but also significantly improves productivity and product quality, reduces production costs, and improves product market competitiveness.
