Abstract

The invention discloses a shaping process for adjusting the boundary dimension of a tooth part with a tooth shaft. The shaping process comprises the following steps of: 1) making a shaping upper die shell and a shaping lower die shell in an open die state; 2) placing the tooth part with the tooth shaft in a tooth part shaping cavity; 3) closing a shaping upper die core II and a shaping lower die core II; 4) extruding the tooth part with the tooth shaft in the tooth part shaping cavity to form a specified boundary dimension; 5) opening the shaping upper die shell and the shaping lower die shell; 6) pushing the shaping lower die core II by a shaping lower die ejector rod; 7) ejecting the shaped tooth part with the tooth shaft in the shaping lower die core II; 8) cutting burrs or glitches onthe outer wall of the shaped tooth part with the tooth shaft by a knife edge of the shaping lower die core; and 9) taking the shaped tooth part with the tooth shaft out of the shaping lower die core II. By the shaping process, the axial dimension and the boundary dimension of the tooth part can be simultaneously shaped, the working efficiency and the product quality are improved, and the shaping process is suitable for production and use requirements.

Description

technical field [0001] The invention belongs to the technical field of general mechanical equipment manufacturing, and in particular relates to a shaping process for adjusting the external dimensions of the teeth of a geared shaft. Background technique [0002] As one of the most basic parts in the mechanical transmission system, gears are widely used in the engineering field, especially in the equipment manufacturing industry. Among them, the spur gear is the most typical gear part, its shape is relatively complex, and the dimensional accuracy, surface quality and mechanical properties are very high. In order to meet the needs of customers, an integrated gear with a pinion (such as figure 1 , 2 As shown), for the tooth shape of the tooth part, due to the limitation of the working principle of the part, the design requires that the part is straight (no slope is allowed) and the roughness requirement is Ra3.2, but due to the forging process, the product must be considered F...
