Process introduction:
Through the one-time processing of pipe molding, high dimensional accuracy, the key size without turning processing, exported to the United States, the world's top five hundred customers highly recognized.

 

Process characteristics:
The inner size of the product is large and the requirement is very high. The product size of the die forging at different temperatures may lead to scrap. Inspired by the preheating of the warm forging die, we tried and developed a method for preheating the cold forging die. By this way, we converted the ordinary cold forging into isothermal die cold forging, and controlled the expansion and shrinkage of the product in 3 wires, thus ensuring the ultra high precision requirements of the inner diameter of the product.

The closed forging is a close net shape forging without a flying edge in a closed die with one or two punches one way or one forming to the extrusion metal. Some car precision parts, such as planetary and half shaft gears, starlike sleeves and crosshafts, etc., if cutting method is adopted, not only the material utilization rate is very low (less than 40%), but also costs much time and costs a lot. These net forgings are produced by block forging technology in foreign countries, which saves most of the cutting and processing, and the cost is greatly reduced.
