Abstract

829,107. Forging toothed gears. SCHONDELMAIER, C. March 26, 1956, No. 9283/56. Class 83 (4). Toothed gears are made by compressing a toroidal blank 1 within a die cavity 5 provided with negative teeth 10 into which the material of the blank is caused to flow. The die assembly comprises a body 4 provided with the teeth 10, a core 2 having a mandrel 11 and a press ram 3 having a recess 12 into which the mandrel engages for centring the ram. As the ram moves downwardly, opposed pressure surfaces 6, 7 cause the blank material to flow laterally into spaces 8, 9 to form a hub and into the tooth spaces 10, thereby to produce a gear 1<SP>1</SP>, Fig. 4 (not shown). After withdrawal of the ram, the core 2 is moved upwardly to eject the finished gear from the die. In another embodiment, Fig. 6, an internally-toothed hub gear 14 is formed, the negative form of the teeth 19 being provided in the peripheral surface of the ram 3.
