[CN 202010933525.6] Four-Hammer Progressive Radial Forging Device and Process for Ring Gear Rigid Wheel of Harmonic Reducer
[CN 202010933525.6] Four-hammer progressive radial forging device and process title of harmonic reducer inner ring gear rigid wheel: Four-hammer progressive radial forging device and process application number of harmonic reducer inner ring gear rigid wheel: CN 202010933525.6 Applicant: Xi 'an Jiaotong University Application Date: 2020-9-8 Patent Type: Invention Application The present invention belongs to the technical field of plastic processing and relates to a four-hammer progressive radial forging device and process of harmonic reducer inner ring gear rigid wheel. A four-hammer progressive radial forging device for the inner gear ring rigid wheel of a harmonic reducer, comprising a radial forging hammer, a core die, a manipulator, and a hydraulic cylinder; the core die comprises an outer gear sleeve and a tapered shaft; the inner hole of the outer gear sleeve is a tapered surface; the outer taper of the tapered shaft is the same as the inner taper of the outer gear sleeve; the manipulator and the hydraulic cylinder can be used to fit or separate the outer tapered surface of the tapered shaft and the inner tapered surface of the outer gear sleeve. The invention adopts a combined core mold structure, the core mold is easy to take out after forming, and avoids the damage of the inner surface of the formed rigid wheel when taking the mold.
