Description

Technical Field

[0001] The utility model relates to an auxiliary tooling, in particular to an auxiliary tooling for free forging of a special-shaped shaft, and belongs to the technical field of special-shaped shaft processing. Background Art

[0002] A special-shaped shaft is a shaft with an asymmetric shape, usually used for rotation or power transmission in a mechanical system. Compared with a conventional symmetrical shaft, the axis of the special-shaped shaft is not at the geometric center of the shaft, but deviates from the axis line;

[0003] Free forging is one of the commonly used forging processes in the production of special-shaped shafts. It is to heat the shaft blank metal block to an appropriate temperature, and then hammer or apply pressure without a mold. The shape and size of the metal are changed by repeated hammering or applying pressure. It has the characteristics of flexible forging, high raw material utilization, simple processing, and good uniformity of organization.

[0004] Traditionally, when free forging special-shaped shaft blanks, they are usually clamped manually or by a large locomotive, so that the position of the shaft blank being hammered can be adjusted according to processing requirements during the free forging process. However, the manual clamping method not only has low work efficiency, but also requires a lot of physical strength of the workers during the processing. The large locomotive is used for clamping, and there are safety risks during operation due to the large overall size of the locomotive. In addition, the workers need to operate inside the locomotive and cannot effectively observe the hammering effect. Therefore, an auxiliary tooling for free forging of special-shaped shafts is proposed. Utility Model Content
