[0040] Multiple sleeves 9 are provided at the bottom of the housing 8. The positions of the sleeves 9 correspond to the positions of the brackets 4, so as to heat the automobile shock-absorbing springs at the same environment and temperature at the same time, thereby improving the heat treatment effect of the springs.

[0041] The electromagnetic heating coil 10 is arranged inside the sleeve 9 through the clamping mechanism 11 and is used to heat the shock-absorbing spring. The electromagnetic heating coil 10 is arranged in a ring shape on the inner wall of the sleeve 9. Compared with the heating tube, the electromagnetic heating coil 10 heats faster and more evenly.

[0042] The gear assembly is arranged inside the housing 8 and is used to drive each sleeve 9 to rotate and heat;

[0043] The gear assembly includes a first motor 12 fixed to the top of the housing 8.

[0054] Example 4

[0055] In conjunction with the first to third embodiments, please refer to Figure 1As shown, the specific improvements are as follows: the front and rear sides of the furnace body 2 are both provided with a front furnace door 32 and a rear furnace door 33 through a slide 31, which are used to seal the front and rear sides of the furnace body 2.

The surfaces of the front furnace door 32 and the rear furnace door 33 are fixedly connected to an electric telescopic rod 34 through a mounting block, and the bottom end of the electric telescopic rod 34 is fixedly connected to the top of the base 1.

[0056] Through the arrangement of the above structure, the electric telescopic rod 34 can drive the front furnace door 32 and the rear furnace door 33 to automatically move up and down without manual opening and closing, thereby reducing safety hazards.

[0057] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0058] During use, a plurality of shock-absorbing springs are respectively sleeved on a plurality of brackets 4 for positioning, and by pulling the first curved plate 20 and the second curved plate 21 in opposite directions, the first magnet 24 is moved out of the mounting groove 25 and separated from the second magnet 26, which can drive the protruding rod 22 to move out of the groove 23, and then the cylinder 43 is moved up and down on the fixing rod 42, so that the height of the bracket 4 can be adjusted, which is convenient for adapting to the hanging of shock-absorbing springs of different models. After the shock-absorbing spring is positioned, the second motor 28 is started to drive the screw rod 29 to rotate, and the fixing block 30 is guided by the slide rail and translated on the screw rod 29, thereby driving the fixing seat 3 to move to the inside of the furnace body 2, corresponding one to one with the position of the sleeve 9;

[0059] After the fixed seat 3 moves into the furnace body 2, the electric telescopic rod 34 is started to drive the front furnace door 32 to move downward to seal the furnace body 2. Then the hydraulic cylinder 6 drives multiple sleeves 9 to move downward through the cross plate 7, which are respectively covered on the outside of each bracket 4, so that the shock-absorbing spring enters the sleeve 9. By starting the internal electromagnetic heating coil 10, the spring sleeved on the bracket 4 is heated. At the same time, a heating plate 18 is also provided on the outside of the bracket 4 to further improve the heating effect. While heating, the first motor 12 is started to drive the intermediate gear 14 to rotate, and the intermediate gear 14 drives the surrounding small gears 16 to rotate, thereby driving multiple sleeves 9 to rotate, which helps to achieve a more uniform heating effect and helps the electromagnetic heating coil 10 to disperse heat and reduce local overheating. After the heating is completed, the sleeve 9 is moved upward, and the electric telescopic rod 34 drives the rear furnace door 33 to move upward. Similarly, the screw mechanism is started again to automatically move the heated shock-absorbing spring out of the furnace body 2 through the fixed seat 3.

[0060] During use, the electromagnetic heating coil 10 is moved toward the outside of the annular sleeve 112 by rotating the threaded rod 113, and the clamping block 115 is driven out of the L-shaped plate 111 by the support plate 114, and then the L-shaped plate 111 is moved toward the inside of the sleeve 9. After it is removed from under the electromagnetic heating coil 10, the electromagnetic heating coil 10 can be removed downward from the sleeve 9 for maintenance or replacement. Conversely, the L-shaped plate 111 passes through the sleeve 9, and the clamping mechanism 11 positions it, so that the electromagnetic heating coil 10 can be installed in the sleeve 9.

[0061] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
