Abstract
A gear forming device comprises an upper die and a lower die. The upper die comprises an upper padding plate, an upper punch, an upper die sleeve and an upper die base. The upper punch is fixed on the lower surface of the upper padding plate, the upper die sleeve is fixed inside the upper die base, and the upper punch is inserted into the upper die sleeve in a sliding mode. The lower die comprises a lower padding plate and a lower swage die with a lower cavity. The lower cavity comprises a communicated first cylindrical cavity and a second cylindrical cavity located below the first cylindrical cavity, wherein the inner diameter of the first cylindrical cavity is larger than the inner diameter of the second cylindrical cavity, and the inner wall of the second cylindrical cavity is provided with a plurality of long-strip-shaped grooves for forming gear splines. The gear forming device can ram a blank and squeeze the splines through the long-strip-shaped grooves at the same time. Compared with existing two procedures, the gear forming device has the advantages that the efficiency of machining gears is improved, and only one set of gear forming device is needed. Compared with two sets of devices used in the prior art, the gear forming device has the advantages that the cost of manufacturing the gear forming device is reduced, and accordingly economic benefits are increased.
