Aluminum casting heat treatment device and working method thereof

Abstract

The invention discloses an aluminum casting heat treatment device and a working method thereof. The aluminum casting heat treatment device comprises a circular ring, the section of the circular ring is in a two-step shape, an inner gear ring is arranged on the inner side of the circular ring, one part of the inner gear ring is lapped on the steps of the circular ring, the other part of the inner gear ring is suspended, and a running auxiliary structure is arranged at the bottom of the suspended part. The inner side of the inner gear ring is in meshing transmission connection with a movable gear, the movable gear is driven by a motor, the left side and the right side of the inner gear ring stretch across a quenching furnace and an aging furnace respectively, the bottoms of the quenching furnace and the aging furnace are not in contact with the inner gear ring, the quenching furnace and the aging furnace are each provided with a pair of automatic doors, and the automatic doors are oppositely arranged and located in the rotating direction of the inner gear ring. A plurality of placing racks are arranged on the inner gear ring, rotate along with the inner gear ring and enter the quenching furnace or the aging furnace. After an aluminum casting is quenched in the quenching furnace, the aluminum casting rotates to enter the aging furnace, the operation of moving the aluminum casting from the quenching furnace to the aging furnace is completed, the moving efficiency is high, and therefore the whole production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of heat treatment of aluminum castings, in particular to a heat treatment device for aluminum castings and a working method thereof. Background technique [0002] Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape and composition of the workpiece, but changes the microstructure inside the workpiece. [0003] Existing aluminum castings are first quenched in a quenching furnace with a higher temperature, and then enter an aging furnace with a lower temperature. In this process, it is all carried out manually, and the handling efficiency is low. Contents of the invention [0004] The object of the present invention is to provide a heat treatment device for aluminum castings and its working method in view of the defects and deficiencies of the prior art. [0005] In order to achieve ...
