Embodiment Construction
[0010] The present invention will be further described below through preferred embodiments in conjunction with the accompanying drawings.
[0011] Such as figure 1 , 2 As shown, a detachment device for the ring gear and the quenching and shaping tool is composed of a heating device 1, a rotary table 2 and a protection table 3. The rotary table 2 is installed in the middle of the protection table 3, and the ring gear and the quenching and shaping tool are placed on the On the rotary table 2, the heating device 1 is evenly distributed on the periphery of the rotary table 2 at 120° with the rotary table 2 as the center. The spray gun 1-1 of the heating device 1 is aimed at the outer circle of the ring gear, and the heating device 1 The propane interface 1-2 and the compressed air interface 1-3 are connected with the air source.
[0012] How to use: After the ring gear and the shaping tool are installed in place, the rotary table 2 rotates, and a certain flow of propane and air ...

The invention discloses a disconnection device of a gear ring and a quenching shaping tool, relating to a thermal treatment device and solving the technical problem that no device is capable of guaranteeing the product quality and conveniently and rapidly separating a quenching shaping tool from a gear ring in the prior art. The disconnection device comprises heating devices, a rotary worktable and a protecting table, wherein the rotary worktable is mounted at the middle of the protecting table, the gear ring and the quenching shaping tool are arranged on the rotary worktable, the heating devices are uniformly distributed at the periphery of the rotary worktable in a 120-degree manner by taking the rotary worktable as a center, spray guns of the heating devices aim at the outer circle of the gear ring, and propane connectors and compressed air connectors of the heating devices are connected with an air source. The disconnection device is used for disconnecting the shaping tool after the gear ring is quenched and has the advantages of simple structure, convenience in operation, good product quality and high production efficiency.
Description
technical field [0001] The invention relates to a heat treatment device in mechanical manufacturing, in particular to a detachment device for a shaped tooling for a ring gear after quenching. Background technique [0002] In order to control the amount of deformation during the quenching process of the ring gear, before the ring gear is quenched and oiled, the shaping tooling with the same size as the inner hole of the ring gear is preheated and inserted into the inner hole of the ring gear. After the quenching oil cooling is completed, the shaping tool and the ring gear are interferingly combined and cannot be separated by themselves. Existing detachment method: install the ring gear together with the shaping tool on the intermediate frequency quenching machine tool, heat the outer circle of the ring gear, and use the expansion difference formed by the temperature difference between the two to make it detach. This method equipment expense is expensive, and production effic...
