2023-12-06

The red punch process of the stamping processing plant is an advanced thermal pressure processing process, which has significant market-oriented economic benefits for mass production. Therefore, the research and development of red punch process has extensive and far-reaching practical significance for machinery manufacturing, daily hardware products, national defense, aerospace parts and other applications. For example, diesel engines, tractors, automobiles, missiles, and many other mechanical parts are very suitable for production using the red punch process.

The red punching process is one of the processing methods for metal materials with little cutting. When red punching, the metal material is heated to a certain temperature, put into the preheated mold, and the metal material is plastically deformed by the one-time reciprocating motion of the pressure machine tool to obtain the required size, shape and good mechanical properties of the stamping parts.

Red punch process has many advantages::

Forming is basically not limited by the external shape of the product parts themselves;

2. Production using common equipment, easy to put into production, suitable for small and medium-sized enterprises production;

3. High productivity, suitable for mass production;

4. Due to the use of core pulling device, the pressed parts are hollow inside, unlike the parts processed by forging dies, which are solid inside. Moreover, the burr thickness of general small red die is about 0.5mm, while the burr thickness of forging dies is generally above 2mm, so the material utilization rate is much higher than that of forging dies;

5. Red punch is a kind of processing technology with little and no cutting. The surface roughness is close to the mold, and the dimensional accuracy can reach 6-7 levels, so its mechanical cutting amount is very small;

6. The mechanical properties of red punching parts are good, because the metal billet after red punching is heated, extruded and cooled, the metal structure changes, eliminating the defects caused by casting or drawing, making the internal crystal structure of the parts linear from inside to outside, improving the mechanical properties of red punching parts;

7. After red punching, the internal grains of the metal have been refined, the density of the metal has been enhanced, and the corrosion resistance of the parts has been improved;

8. Suitable for all kinds of colored or black metal processing.

Red punching process can save a lot of metal raw materials. It not only has high production efficiency, but also saves labor and materials, can improve economic efficiency, and can significantly improve product quality.

The red punch process is an advanced professional process developed from modern precision forging and hot extrusion. With the advancement of society and the development of science and technology, the machinery industry has put forward new mechanical strength requirements for mechanical parts. To improve the mechanical strength, two methods are generally used, one is to change the material of the parts, and the other is to change its processing method. Red punching process is one of the effective methods to improve the mechanical properties of stamping parts by changing the processing method, so it has strong vitality and good development prospects like its forging process.
