[0002] Double-turn induction hardening coil is a coil structure used for induction heating and hardening. It consists of two or more coils with the same number of turns. It is usually used to uniformly heat and harden long workpieces. By passing an alternating current through the coil, an alternating magnetic field is generated, thereby inducing eddy currents in the workpiece and rapidly heating the workpiece surface.

After the cooling is completed, the rack needs to be tempered, so the rack needs to be placed in the coil again. This process takes a lot of time, thus affecting the processing efficiency of the rack.

[0004] To this end, this case proposes a double-turn induction hardening coil for improving rack deformation to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-2As shown, a double-turn induction quenching coil for improving rack deformation includes a fixed column 1, a slide groove 2 is opened at one end of the fixed column 1, a threaded rod 3 is rotatably connected to one end of the slide groove 2 and passes through the fixed column 1, a hand wheel 4 is fixedly connected to the other end of the threaded rod 3, a movable sleeve 5 is threadedly connected to the outer wall of the threaded rod 3, the movable sleeve 5 and the slide groove 2 are slidably connected, and two induction coil bodies 6 are fixedly connected to one end of the movable sleeve 5 away from the fixed column 1, a plurality of evenly arranged watering holes 7 are opened on the inner walls of the two induction coil bodies 6, and a water supply pipe 8 is fixedly connected to the top of the two induction coil bodies 6.

[0022] In this embodiment, a fixing plate 9 is fixedly connected to both sides of the slide slot 2 at one end of the fixing column 1, and a limiting column 10 is slidably passed through the fixing plate 9, and a groove 11 is formed at one end of the limiting column 10 close to each other;

[0023] By placing the rack in the groove 11 and limiting the rack by the limiting column 10, the rack is made more stable during quenching.

[0024] In this embodiment, the end of the limit column 10 away from each other is fixedly connected with a fixed block 12, and the two sides of the fixed block 12 close to the end of the limit column 10 are fixedly connected with a tension spring 13, and the tension spring 13 is fixedly connected to the fixed plate 9;

[0025] Through the elastic effect of the tension spring 13, a pulling force can be generated on the limiting column 10, thereby completing the limiting of the rack.

[0026] In this embodiment, a connecting column 14 is fixedly connected to the middle of the other end of the fixing column 1, and a mounting plate 15 is fixedly connected to the other end of the connecting column 14;

[0027] The mounting plate 15 can be installed at a suitable position through the mounting holes.

[0028] In this embodiment, the limiting posts 10 are symmetrically distributed about the center line of the fixing post 1, the number of tension springs 13 on both sides is equal, the groove 11 is arranged at the center line position of the induction coil body 6, and the groove 11 is used to limit the rack;

[0029] The number of tension springs 13 is equal, so the tension that can be generated is also the same, so that the rack is just at the center line of the induction coil body 6, and the rack is better quenched to prevent deformation.

[0030] It should be noted that the utility model is a double-turn induction quenching coil for improving the deformation of the rack. When in use, the rack is first placed between the grooves 11, and the rack is limited by the elastic action of the tension spring 13 so that it is placed inside the induction coil body 6. Therefore, racks of different sizes can be clamped and limited, thereby improving practicality and stability during the quenching process.

[0031] Then, the hand wheel 4 is rotated and the threaded rod 3 is rotated. Due to the thread effect of the threaded rod 3, the movable sleeve 5 can be moved, and when the rotation stops, the movable sleeve 5 can be prevented from automatically deviating. The movable sleeve 5 moves with the induction coil body 6, and the rack can be quenched. After the quenching is completed, water can be sprayed on the rack through the water supply pipe 8 and the water spray hole 7. The water flow rate can be controlled to prevent the rack from cooling too quickly, thereby reducing the generation of residual stress and preventing the rack from deformation.

[0032] After cooling, the rack is tempered again by the induction coil body 6 to reduce the generation of residual stress as much as possible. In the whole process, the rack does not need to be taken and placed many times, so the processing efficiency of the rack can be improved.
