The red punching 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 the red punching process has extensive and far-reaching practical significance for applications such as machinery manufacturing, daily hardware products, national defense, and aerospace parts. For example, many mechanical parts such as diesel engines, tractors, automobiles, missiles, etc. are very suitable for production using the red punch process.

The red punching process is one of the machining methods for metal materials with little and no cutting. During 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 movement of the press machine to obtain stamping parts with the required size and shape and good mechanical properties.

The red punching process has many advantages::

1. Forming is basically not restricted by the external shape of the product part itself;

2. The production uses common equipment, which is easy to put into production and suitable for small and medium-sized enterprises;

3. High productivity, suitable for mass production;

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

5. Red punching is a machining process with little and no cutting. The surface roughness is close to that of the mold, and the dimensional accuracy can reach 6-7, so its mechanical cutting volume is very small;

6. The mechanical properties of the red stamping parts are good. After the red stamping, the metal blanks are heated, extruded, and cooled, and their metal structure changes, eliminating the original defects caused by casting or drawing, and making the internal crystal structure of the parts appear The linear shape from the inside to the outside improves the mechanical properties of the red-punched parts;

7. After red punching, the internal crystal 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.

9. The 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 punching process is an advanced professional process that has just been developed on the basis of 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 the processing method. The 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 the forging process.
