Forging shaft processing procedures

Forging shaft is metal in solid state after heating through forging and pressing forming, it requires metal to have good thermoplastic, general forging shaft are steel parts, its high strength, plastic calculation and blanking is one of the important links to improve the utilization rate of materials, to achieve blank refinement. Too much material not only causes waste, but also aggravates die wear and energy consumption.

If the blanking does not leave a little margin, it will increase the difficulty of process adjustment and increase the rejection rate. In addition, the quality of blanking end face also has an impact on the process and forging shaft quality.

The purpose of heating is to reduce the deformation force of forging shaft and improve metal plasticity. But heating also brings a series of problems, such as oxidation, decarbonization, overheating and burning. Accurate control of initial and final forging temperatures has great influence on the microstructure and properties of forging shafts. Forging shaft is suitable for manufacturing important parts with large force and high requirements, such as bolts, shafts, gears and so on.
