A clutch hub tooth profile roll forming device and processing technology

Abstract

The invention relates to a clutch hub tooth profile roll forming device and a machining technique, and belongs to the field of vehicle manufacturing. The forming device comprises a spindle, a core mold and an ejector rod arranged coaxially in sequence. The spindle can not only rotate but can feed axially; tooth profiles are evenly distributed at the lower end of the outer wall of the core mold, the upper end of the core mold is mounted on the spindle, the lower end of the core mold is sleeved with a cylindrical workpiece, and the synchronous action of the core mold with the spindle can be ensured by the action of the ejector rod; the periphery of a workpiece is provided with 3-4 rollers, and the number of the rollers can be correspondingly selected according to the number of teeth; the outer profile of each roller is matched with the outer profile of a clutch hub to be machined, and each roller can be fed horizontally in the direction perpendicular to the spindle. The machining and manufacturing of the clutch hub with the inner side and the outer side both provided with longitudinal teeth are realized, and the forming device is simple, high in forming efficiency and forming precision, and flexible and universal. The tooth profile filling property is ensured while forming internal and external teeth, thereby achieving double improvement of forming quality and efficiency.

Description

technical field [0001] The invention relates to a technology in the field of vehicle manufacturing, in particular to a roll forming device and a processing technology that adopts a multi-point successive roll forming method to reduce the cost of forming equipment and improve the quality and efficiency of clutch hub tooth formation. Background technique [0002] The gearbox clutch is composed of a clutch hub, friction plates, steel plates, etc. The connection and disconnection of the torque is realized through the compression and release of the friction plates, especially one of the key components of the dual clutch transmission or automatic transmission. As the supporting structure of the clutch friction plate and steel plate, the clutch hub’s accuracy and strength directly affect the service performance and life of the vehicle clutch. The clutch hub is a complex deep cylinder with a large surface area. Its typical features are circumferentially evenly distributed tooth groo...
