Abstract

The invention belongs to the technical field of machining, and particularly relates to a 3J21 thin-wall wave spring aging tool and a wave spring machining method. The aging tool comprises an upper pressing block (2), a positioning pin (3), a lower pressing block (4) and a positioning shaft (6), the upper pressing block (2) and the lower pressing block (4) are provided with through holes, the positioning shaft (6) penetrates through the through holes, the lower end face of the upper pressing block (2) and the upper end face of the lower pressing block (4) are provided with a plurality of wave crests and wave troughs matched with the wave spring, and the positioning shaft (6) is fixedly connected with the lower pressing block (4). A first lateral through hole is formed in the portion, located in the through hole of the upper pressing block (2), of the positioning shaft (6), a second lateral through hole is formed in the corresponding position of the upper pressing block (2), the positioning pin (3) penetrates through the first lateral through hole and the second lateral through hole, the wave trough of the upper pressing block corresponds to the wave crest of the lower pressing block, and vice versa. The wave spring subjected to vacuum aging is small in deformation, and various technical indexes of the spring are guaranteed.

Description

technical field [0001] The application belongs to the technical field of mechanical processing, and in particular relates to a 3J21 thin-wall wave spring aging tool and a wave spring processing method. Background technique [0002] At present, the manufacturing method of 3J21 thin-walled wave spring is to blank the 3J21 sheet with the required thickness, punch the shape after blanking, and then transfer to the heat treatment process. The heat treatment operator will discharge the wave spring flatly on the tray for vacuum aging, and finally Check the spring and height. [0003] The above method mainly has the following problems. 1. Machining mainly ensures the shape and size of the parts, but does not measure the difference between the same plate after the material is cut, resulting in the impact of the material thickness on the elastic force after vacuum aging. 2. Vacuum aging is to place the wave spring flatly on the tray and use a vacuum annealing furnace for aging. Fix...
