[0002] Automobile suspension spring is a kind of spring with good memory elasticity, high strength and bending resistance. It is hot-pressed in production using a hot press. The alloy steel bar is heated red and then wound on the outer surface of the output shaft of the hot press to form it into a spring state. It is then annealed and other operations are performed to eliminate stress and form a high-strength spring.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0024] The embodiment of the present application solves the problem that in actual application, different spring diameters are required for different vehicle models by providing a suspension spring thermal pressing device, which results in the need to replace different output shafts during production and the need to replace the support seat in a matching manner, which is costly and troublesome to replace.
[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0026] The embodiment of the utility model discloses a suspension spring thermal pressing device.
[0027] According to the attached Figure 1-5 As shown, it includes a thermal pressing unit 1, which includes a base 11, a sliding carrier 12, a fixed support 13 and an electric rotating shaft 14. The sliding carrier 12 is slidably arranged on the top of one end of the base 11, and the fixed support 13 is fixedly installed on the top of the other end of the base 11. The electric rotating shaft 14 is rotatably connected to the middle of the sliding carrier 12, and the end of the electric rotating shaft 14 passes through the fixed support 13. The top of the base 11 is rotatably connected to a stepping screw 15, and the end of the stepping screw 15 is rotatably connected to the fixed support 13. The sliding carrier 12 is threadedly connected to the outer surface of the stepping screw 15, and a driving motor is fixedly installed on the top of one end of the base 11, and the output end of the driving motor is fixedly installed to one end of the stepping screw 15.
[0028] The electric rotating shaft 14 includes an electric rotating motor and a rotating shaft. The rotating motor is fixedly mounted on the sliding carrier 12, and the rotating shaft is driven to rotate by the rotating motor.
[0029] The output end of the heat-pressure unit 1 is provided with an outer diameter adjustment member 2, which includes a plurality of metal sleeves 21 sleeved and installed on the output end of the heat-pressure unit 1. The front end of the heat-pressure unit 1 is provided with an adaptive support positioning member 3;
[0030] The adaptive support positioning member 3 includes a wedge-shaped sliding support member 31 and an inner conical ring 32. The inner conical ring 32 is slidably arranged on the back of multiple groups of wedge-shaped sliding supports 31 arranged in an annular array, so that a single inner conical ring 32 can synchronously push multiple wedge-shaped sliding supports 31, which is easy to operate. At the same time, the wedge-shaped sliding supports 31 can ensure synchronous movement toward the center in multiple directions, and the centering effect is good.
[0031] The wedge-shaped sliding support 31 includes a support head 311 and a wedge block 312 fixedly arranged on the back of the support head 311. The inner conical ring 32 is against the inclined surface of the wedge block 312, thereby realizing the horizontal movement of the inner conical ring 32 and pushing the wedge block 312 to move perpendicular to the center position of the top slot of the fixed support 13.
[0032] The inner conical ring 32 and the wedge block 312 are both arranged inside the fixed support 13 . A connecting shaft 313 is fixedly connected between the support head 311 and the wedge block 312 , and the connecting shaft 313 passes through the fixed support 13 .
[0033] The outer wall of the connecting shaft 313 is movably sleeved with a return spring 314, and the back side of the wedge block 312 is movably inserted with a positioning shaft 315. The positioning shaft 315 is fixedly connected to the inside of the fixed support 13. The positioning shaft 315 can prevent the connecting shaft 313 from deflecting when sliding. When the inner conical ring 32 moves away from the wedge block 312, the return spring 314 pushes the connecting shaft 313 toward the inner wall of the fixed support 13 for reset.

[0035] By rotating the adjusting screw 33 clockwise, the inner conical ring 32 slides toward the side close to the wedge block 312, pushing the wedge block 312 toward the axis of the electric rotating shaft 14, so that multiple support heads 311 are pressed against the outer surface of the metal sleeve 21, thereby adapting to the production and processing of springs of different diameters.
[0036] The metal sleeve 21 is movably sleeved on the front end outer surface of the electric rotating shaft 14. The metal sleeve 21 and the outer surface of the electric rotating shaft 14 are respectively welded with fixed flange rings 22. Fixing bolts are installed between multiple groups of fixed flange rings 22. The front end of the electric rotating shaft 14 is installed with a blocking piece 23 through bolts. The blocking piece 23 is abutted against the end of the metal sleeve 21. The outer surface of the blocking piece 23 is installed with a clamp 16. When in use, the corresponding number of metal sleeves 21 are selected according to the spring diameter to be processed and sleeved on the outer surface of the electric rotating shaft 14 in sequence, and the multiple fixed flange rings 22 are fixed together with bolts. Then the blocking piece 23 is installed on the end of the electric rotating shaft 14, and the end of the spring is clamped and fixed by the clamp 16.
