Technical Field
[0001] This utility model relates to the field of spring heat treatment technology, and in particular to a spring heat treatment device. Background Technology
[0002] A spring is a mechanical part that works by utilizing elasticity. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. Although it is a small industry in manufacturing, its role is absolutely not to be underestimated. Springs need to undergo heat treatment processes during production.
[0003] Existing spring heat treatment devices mostly use a seat-type support frame structure to support the heat-treated springs. However, removing the springs from the seat-type support frame structure requires multiple processes such as lifting, pushing, and suspending, which makes the spring removal operation cumbersome, reduces the efficiency of spring heat treatment, and requires the use of external equipment for auxiliary operations multiple times. Therefore, this application designs a spring heat treatment device to solve the above problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the cooperation between the limiting guide rod and the transmission worm gear facilitates the stable pushing of the sliding spring component materials, further improving the stability of spring thermoforming and thus enabling the material forming anti-rebound function.

A movable support seat 6 is provided on one side of the shaping roller 2, and a fixed support seat 10 is provided on the other side. The shaping roller 2 is rotatably engaged between the movable support seat 6 and the fixed support seat 10. The guide limiting assembly is located between the shaping roller 2 and the heating box 1. The heating box 1 allows for better heating of the spring components; the guide... The limiting assembly consists of a transmission worm gear 4, a lead screw 11, and a limiting guide rod 5. The limiting guide rod 5 is threaded onto the lead screw 11. The end of the lead screw 11 is equipped with a transmission worm wheel for meshing with the transmission worm gear 4. A first motor is located on the side of the transmission worm gear 4, and the output shaft of the first motor is coaxially fixed to the transmission worm gear 4. Through the setting of the guiding and limiting assembly, the spring component material can be better pushed, facilitating its winding and shaping on the shaping roller 2. A hinged rotating seat is located on the side of the movable support base 6. The movable support base 6 is fixed on the rotating shaft of the hinged rotating seat. Through the setting of the movable support base 6 and the hinged rotating seat… The movable support 6 is designed to facilitate the release of the support on the shaping roller 2, thereby allowing the support frame 15 to push the heated and shaped spring away from the shaping roller 2. A transmission docking block 9 is provided at one end of the shaping roller 2 near the fixed support 10. An electrically controlled limiting gripper 8 is clamped on the side of the shaping roller 2 near the transmission docking block 9. The transmission docking block 9 allows for better connection of an external rotating device to drive the shaping roller 2 to rotate, and the electrically controlled limiting gripper 8 clamps the spring, thus completing the heating and shaping of the spring. A support frame 15 is slidably provided at the lower end of the shaping roller 2. A mating toothed plate 13 is installed on the side of the support frame 15. The side end of the 3 is meshed with a gear 14, and the lower end of the gear 14 is equipped with a second motor 7. The motor shaft of the second motor 7 is coaxially fixed with the gear 14. Through the setting of the gear plate 13 and the gear 14, the support frame 15 can be pushed better, thereby pushing out the heated and shaped spring. The side wall of the heating box 1 is provided with a guide support bracket. The limit guide rod 5 is provided with an installation groove at equal intervals. A limit rotating block 12 is installed in the installation groove by a bolt. Through the setting of the guide support bracket and the limit rotating block 12, the spring component material can be better limited, thereby stably winding and shaping the spring.
[0020] Working Principle: When using this utility model, firstly, the motor and equipment of the device are connected to the power supply, and an external rotating device is connected to the side end of the shaping roller 2 through the transmission docking block 9. Then, the spring component material is input into the heating box 1. The eddy current heating device at the upper end of the heating box 1 can better heat the spring component material. Through the rotation transmission of the conduction roller 3 and the limiting guidance of the guide support frame and the limiting rotating block 12, the spring component material is pushed to the gripper position of the electrically controlled limiting gripper 8. Then, the electrically controlled limiting gripper 8 is activated to clamp and fix the spring component material. Then, by activating the external rotating device, the shaping roller 2 is rotated. At the same time, the first motor is activated to drive the spring component material on the limiting rotating block 12 to slide along through the guide limiting component until the heating and shaping of the spring is completed. Then, the movable support seat 6 is rotated and opened. Then, the second motor 7 is activated to push the spring out of the shaping roller 2 through the support frame 15. Finally, the spring is sent into the quenching pool for quenching through the external lifting device. Then, subsequent heat treatment is carried out as required. The use of the device is thus completed.
