Stamping die of inner convex rib of one-way clutch transmission sleeve

Abstract

The invention discloses a stamping die of inner convex rib of a one-way clutch transmission sleeve, comprising an upper die base and a lower die base in guide connection through a guide pole. The stamping die is characterized in that: a strip-shaped convex die is mounted at the lower end of the upper die base; the lower die base is fixedly provided with a mounting base with an arc-shaped slot; a rotary shaft is provided with a concave die cavity matched with the convex die; the end portion of the rotary shaft is connected with a locating chuck with locating grooves distributed at the periphery; a locating pin matched with the groove is mounted at the end portion of the lower die base; a transmission sleeve to be processed is sleeved outside the rotary shaft; both the rotary shaft and the transmission sleeve are arranged in the arc-shaped slot of the mounting base; and the locating pin is matched with the locating groove. The invention adopts a one-stamping manner to shape the transmission sleeve simply, and satisfies the tolerance requirement of top circle and root diameter of the transmission sleeve.

Description

technical field [0001] The invention belongs to the field of stamping dies, in particular to a stamping die for inner convex ribs of a one-way clutch transmission sleeve. Background technique [0002] The starter motor one-way clutch is an important part of the starter motor, which transmits the torque and power of the starter motor to the engine to start the engine. When the engine is running its torque cannot be reversed to the starter motor. Among them, the transmission sleeve is the key part of the one-way device, and the torque and power of the starter motor are transmitted to the output of the center shaft through five uniformly distributed inner ribs. The structure and space of this part are so that the pulling and inserting process cannot be used, and the transmission adopts the method of helical spline. Therefore, extrusion or stamping processes can only be used to achieve plastic deformation of the material, which seems to be a simple forming process, but it is v...

AI Technical Summary

Problems solved by technology

Therefore, the plastic deformation of the material can only be achieved by extrusion or stamping process, which seems to be a simple forming process, but it is very difficult

The debugging technology requires high requirements. The positioning of the five sliders, the damage or uneven wear of the upper and lower cones must be replaced at the same time before debugging, otherwise the deformation of the five places will be different, resulting in unqualified parts. There are more than forty parts in the entire equipment, and the processing requirements are very high.
