Abstract

The invention provides a carburization combined tool and heat treatment method of synchronizer combined gears. The carburization combined tool comprises a main bottom plate, flat plates, locating supports, flat supporting gaskets and flat pressing gaskets. The number of the flat plates is at least one, and the main bottom plate and the flat plates are sequentially arranged in parallel from bottom to top and are connected through at least one stand column. The multiple corresponding locating supports are vertically arranged on each flat plate and are transversely or vertically arranged on the flat plate in a staggered manner. The lower portion of each locating support is detachably provided with the corresponding flat supporting gasket, and the lower surface of each flat supporting gasket is in contact with the upper surface of the corresponding flat plate. The upper portion of each locating support is detachably provided with the corresponding flat pressing gasket. At least one combined gear can be placed between each flat pressing gasket and the corresponding flat supporting gasket from bottom to top, and the lower surface of each flat pressing gasket is in contact with the upper surface of the corresponding uppermost combined gear. According to the carburization combined tool and heat treatment method of the synchronizer combined gears, the problem of heat deformation generated after combined gear quenching is solved, and the precision of finished products is improved.

Description

technical field [0001] The invention belongs to the technical field of metal heat treatment, and in particular relates to a carburizing combined tooling combined with a synchronizer and a gear and a heat treatment method. Background technique [0002] The combined gear in the synchronizer is a thin-walled part. The biggest problem of the thin-walled part after heat treatment is that the plane of the thin-walled part is prone to distortion and deformation. At present, the heat treatment of the combined gear in the synchronizer is carburized and quenched. , The equipment can be carried out by using a box-type carburizing furnace or a continuous carburizing production line, and the furnace loading method can be a hanging method or a single flat-mounted method. but for figure 1 For the workpiece shown, the deformation after carburizing and quenching has been a serious problem for a long time. After heat treatment, the flatness of the workpiece is seriously out of tolerance. In ...
