Gear quenching device

Abstract

The invention discloses a gear quenching device which comprises an upper die and a lower die. The periphery of the upper die is moulded as an outer compression ring structure, the upper die is internally provided with an inner compression ring, a gear is placed on the lower die to position, and the lower end face of the outer compression ring structure moulded on the upper die is contacted with the tooth surface of the gear, while the lower end face of the inner compression ring is contacted with a convex table-board of the gear. According to the device provided by the invention, an extension die, the outer compression ring, the inner compression ring and the like of existing device are integrated to the upper die which can transfer pressure to the gear to quench the gear. The gear can be further positioned when the gear is quenched. All steps of quenching can be finished by match of the upper and lower dies, so that the structure of the device is greatly simplified and the manufacturing cost of the device is lowered. The whole device is simple in structure, low in cost, and economical and practical.

Description

technical field [0001] The invention belongs to the technical field of gear processing, in particular to a gear quenching device applied to a gear quenching press. Background technique [0002] The existing gear quenching press consists of expansion dies, outer pressure rings, inner pressure rings, lower dies and other devices, and separate mechanisms are required to transmit the force to the expansion dies, outer pressure rings, inner pressure rings, and lower dies. In this way, the equipment structure and control are relatively complicated, resulting in relatively high equipment costs. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and provide a quenching device that can realize gear quenching only by transmitting pressure to the gear from the upper mold, thereby simplifying the equipment structure and reducing the manufacturing cost of the equipment. [0004] The technical solution of the present inventio...
