Abstract

The invention discloses an inner gear ring correction constant-pressure machine, and relates to a supporting device for heat treatment of an inner gear ring. An upper crossbeam (1) and a lower crossbeam (10) are fixedly connected with each other through four upright bodies (2) to form a framework structure, the upper crossbeam (1) and the upright bodies (2) are fixed through upright body fixed nuts (3), the bottom of the framework structure is provided with a base (11), a hydraulic cylinder (7) is arranged inside the framework structure, a lower correction mold (6) and an upper correction mold (4) are connected above the hydraulic cylinder (7), the lower part of the hydraulic cylinder (7) is provided with a pressure releasing screw (9), and the side edge of the hydraulic cylinder (7) is provided with a pulling handle hole (8). The inner gear ring correction constant-pressure machine is simple in structure, the correction mold is reliable to demold, and easiness for loading and unloading a workpiece can be realized, and convenience in operation can be realized; and convenience, safety and sensitivity in local operation can be realized.

Description

technical field [0001] The invention relates to ancillary equipment for the heat treatment of an inner ring gear, in particular to a correcting and balancing press for the inner ring gear. Background technique [0002] Heat treatment deformation is an eternal subject, and deformation control has always been a difficult point for heat treatment technicians in the heat treatment field. The inner ring gear will inevitably produce more or less deformation during the heat treatment process, and this must be avoided when the product is delivered. There is a relationship between the two that coexists but needs to be avoided, and only the corresponding method can be used Try to control the amount of deformation as small as possible. Calibration of arc parts has always been a difficult problem in heat treatment, and general calibration machines cannot meet the requirements. Contents of the invention [0003] Aiming at the deficiencies existing in the prior art, the object of ...
