Abstract
The invention discloses an axial multi-point roll forming device for a clutch hub tooth shape. In order to overcome the problems of single forming equipment and low forming quality in the prior art, the device comprises a frame, a main transmission mechanism, a mandrel clamping and indexing mechanism, a gear Form rolling mechanism and ejection guide mechanism; frame includes upper beam, rear wall, 2 column side panels, lower beam and bottom plate; main transmission mechanism includes main AC servo motor support seat, No. 1 guide rail and No. 1 slide block; the base plate is fixed on the foundation, the rear wall plate is parallel to the two column side plates and fixed vertically on the rear side of the base plate; the upper beam is vertically fixed on the rear wall plate and the top of the two column side plates; the lower beam is parallel The main transmission mechanism is installed on the frame through the main AC servo motor support seat and the No. 1 guide rail; the mandrel clamping and indexing mechanism is installed on the No. 1 slider; the toothed rolling mechanism is installed on the mandrel. On the lower beam directly below the clamping indexing mechanism; the ejection guide mechanism is installed on the bottom plate below the lower beam.
Description
technical field [0001] The invention relates to a special equipment for machining the clutch hub tooth profile of a vehicle automatic transmission or a dual-clutch transmission. More precisely, the invention relates to a clutch hub tooth profile axial multi-point rolling forming device. Background technique [0002] Toothed clutch hub is one of the key components of vehicle dual-clutch transmission or automatic transmission. The clutch hub is a complex deep cylindrical thin-walled part with a large surface area. Its typical characteristics are circumferentially uniform tooth profile and local thickness changes. In particular, the wall thickness of the tooth-shaped part is uneven and there is a very small fillet, the overall quality requirements are high, and the forming is difficult, and as the supporting structure of the clutch friction plate and steel plate, torque needs to be transmitted during the working process, which has great impact on the manufacturing process. High...
