[0023] like Figures 1 to 5 As shown, the L-shaped push plates 8 at different cross-sectional positions are arranged in a staggered manner.

[0024] The spring washers inside the annealing box 1 are pushed in an interlaced manner, thereby increasing the contact area and efficiency between the entire spring washers and the hot air inside the annealing box 1 .

[0025] like Figures 1 to 5 As shown, a rotating rod 10 is rotatably installed in the middle of the annealing box 1, and a pushing motor 11 for controlling the rotation of the rotating rod 10 is fixedly installed at one end of the annealing box 1. A limiting block 12 is symmetrically fixedly installed in the middle of the rotating rod 10, and the mounting tube 7 is slidably installed on the outside of the pushing motor 11. A limiting groove 13 is provided inside the mounting tube 7 at a position corresponding to the limiting block 12, and the limiting groove 13 is slidably connected to the limiting block 12. A mounting rod 14 is fixedly installed on the inner wall of the annealing box 1, and a guide rod 15 is fixedly installed at one end of the mounting rod 14 away from the annealing box 1. A guide groove 16 is provided on the outer side of one end of the mounting tube 7 close to the guide rod 15, and the guide groove 16 is slidably connected to the guide rod 15, and the guide groove 16 includes an arc groove 17 and a V-shaped groove 18, and the arc groove 17 and the V-shaped groove 18 are connected.

[0026] The push motor 11 drives the rotating rod 10 to rotate, which will synchronously drive the installation cylinder 7 to rotate. The L-shaped push plate 8 will push the spring washer inside the annealing box 1 to improve the contact area and efficiency between the overall spring washer and the hot air inside the annealing box 1. When the guide rod 15 is inside the arc groove 17, the installation cylinder 7 continues to rotate.

[0028] The stability of the movement of the installation cylinder 7 restricted by the guide rod 15 is improved.

[0029] like Figures 1 to 5 As shown, one end of the L-shaped push plate 8 away from the mounting tube 7 is fitted with the inner wall of the annealing box 1 .

[0030] The spring washer fitted inside the annealing box 1 can be pushed completely as a whole.

[0031] like Figures 1 to 5 As shown, the reciprocating mechanism includes a fixed plate 19, a drive motor 20, a turntable 21 and a connecting rod 22. The annealing box 1 is fixedly installed with a fixed plate 19 near the heat preservation cylinder 4 and the heat dissipation cylinder 5. The drive motor 20 is fixedly installed at one end of the fixed plate 19, and the turntable 21 is fixedly installed at the output end of the drive motor 20.

[0033] The utility model provides an annealing device for the production of spring washers, and the specific working principle is as follows:

[0034] When the device is in use, the spring washer is placed from the feed port 2 into the annealing box 1, and the spring washer is heated by the operation of the electric heating plate 9. At the same time, the turntable 21 is driven to rotate by the driving motor 20, and the connection between the turntable 21 and the piston 6 by the connecting rod 22 will drive the piston 6 to slide back and forth inside the heat preservation cylinder 4, which will make the internal air flow of the annealing box 1 circulate, and improve the heating speed of the spring washer. When the temperature is too high, the turntable 21 is driven to rotate by starting another driving motor 20, and the connection between the turntable 21 and the piston 6 by the connecting rod 22 will drive the piston 6 to slide back and forth inside the heat dissipation cylinder 5, and the hot air inside the annealing box 1 is circulated and filled in the heat dissipation cylinder 5 for heat dissipation, thereby reducing the temperature, facilitating the heating of the spring washer and the heat dissipation of the hot air inside the annealing box 1;

[0035] When the spring washer is annealed, the rotating rod 10 is driven to rotate by the pushing motor 11, which will synchronously drive the installation cylinder 7 to rotate. The L-shaped pushing plate 8 will push the spring washer inside the annealing box 1, thereby increasing the contact area and efficiency between the overall spring washer and the hot air inside the annealing box 1. When the guide rod 15 is inside the arc groove 17, the installation cylinder 7 continues to rotate. When the guide rod 15 is inside the V-shaped groove 18, the installation cylinder 7 will slide left and right due to the squeezing of the guide rod 15. The L-shaped pushing plate 8 will push the spring washer inside the annealing box 1 left and right, thereby further increasing the contact area and efficiency between the overall spring washer and the hot air inside the annealing box 1.
