Abstract

The invention discloses a multi-point rolling forming device and technology for hub teeth of a clutch hub. The multi-point rolling forming device comprises a driving shaft and three driven shafts which are uniformly distributed in the circumferential direction of the driving shaft, wherein the driven shafts are parallel to the driving shaft; a driving gear is arranged on the driving shaft; a driven gear meshed with the driving gear is arranged on each driven shaft; one end of the driving shaft is in transmission connection with a driving device; the other end of the driving shaft is fixedly connected with one end of a core mold; the core mold is coaxial with the driving shaft; the core mold is used for sleeving a cylindrical blank; a stop block for limiting axial movement of the cylindrical blank is arranged at the other end of the core mold; a roller is arranged on each driven shaft and corresponds to the core mold; a core mold tooth profile is arranged on the side wall of the core mold; a roller tooth profile is arranged on the side wall of each roller and corresponds to the core mold tooth profile; and the circumferential length of each roller tooth profile is one third of thatof the hub teeth of the clutch hub. According to the multi-point rolling forming device and technology for the hub teeth of the clutch hub, the forming efficiency and quality of the hub teeth of the clutch hub are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a clutch hub gear multi-point roll forming device and process. Background technique [0002] The clutch is one of the key components of the vehicle transmission system. The processing accuracy and quality of the clutch need to be very high to ensure the normal operation of the vehicle, especially the processing of the clutch hub. The clutch hub is a thin-shell part with evenly distributed teeth in the circumferential direction, and it needs to cooperate with other parts during use. It has certain processing accuracy requirements, especially the forming and filling of the hub tooth fillet. difficulty. [0003] At present, the existing clutch hub tooth forming methods mainly include the following types: [0004] (1) Extrusion forming process [0005] The extrusion forming process is a composite forming process of stamping and extrusion. According to the differen...
