Abstract
A feeding mechanism for a forging machine includes a roller unit consisting of a pair of feeding rollers. Two rotating shafts are connected respectively and fixedly to the feeding rollers at an end portion, and to outer and inner driven gears at the other end portion. The inner and outer driven gears mesh with each other. A driving gear meshes with the inner driven gear, and rotates reciprocally within a predetermined angular range. The driving gear and the outer driven gear are sector gears. Each of the inner and outer driven gears is mounted on the corresponding rotating shaft by means of a unidirectional bearing so as to convert reciprocal rotation of the driving gear into intermittent unidirectional rotation of each of the rollers. Each of the rollers is provided with a braking member, which includes a circumferentially extending brake plate that presses against an outer periphery of the corresponding roller.
