Description

Top die mechanism for forging output shaft of speed reducer Technical Field The utility model relates to the technical field of production of speed reducers, in particular to a top die mechanism for forging an output shaft of a speed reducer. Background The speed reducer is a mechanical device which converts an input high rotating speed into a low rotating speed and outputs larger torque through the meshing action of a transmission structure such as a gear, a worm or a planetary gear, and the like, and an output shaft blank of the speed reducer is mainly produced through hot forging and then is subjected to machining and heat treatment to meet the use requirement. In the hot forging process of the blank of the output shaft of the speed reducer, the blank is pressed into a die by a hydraulic press, the blank is ejected out by a die ejecting mechanism, a high-temperature oxidation layer can fall in the forging process, the oxidation layers fall and then are easily contacted with a sealing piece of a hydraulic cylinder at the bottom, the production environment temperature is high, the sealing piece is extremely easy to damage, the oil cylinder is extremely inconvenient to replace, and the cost is high.
