Abstract

794,696. Forging toothed gears; making dies. FUCHS, H. J. Sept. 5, 1956, No. 27226/56. Classes 83 (2) and 83 (4). A synchronizing ring for a gear box, having external teeth 2, Fig. 2, and internal slots 4, is made by forging an annular blank in one operation between dies 5, 6, Fig. 3. The external teeth impressions 2<SP>1</SP> are provided in the upper die and the impressions 4<SP>1</SP> for the inner guide slots are provided in a cylindrical extension 8 of the lower die. This cylindrical extension engages within a recess 7 of the upper die for assisting the conventional guide columns 9 in centralizing the two dies. Spaces 11, 12 are provided for excess metal. Ejectors 13 remove the forged ring from the bottom die. Making dies.-The teeth impressions 2<SP>1</SP> in the upper die are formed by means of a hardened master die which is pressed into the upper die.
