Description

Technical Field

[0001] This utility model relates to the field of tapered roller processing technology, and in particular to a medium-frequency quenching induction device for tapered roller processing. Background Technology

[0002] In the processing of tapered rollers, quenching is a crucial step in improving their surface hardness, wear resistance, and fatigue strength. However, for parts like tapered rollers with significant differences in cross-sectional area between the large and small ends, traditional medium-frequency quenching inductors face numerous challenges. Because the gap between the coil of a conventional medium-frequency quenching inductor and the part varies greatly at the large and small ends of the tapered roller, the small end struggles to receive sufficient heating energy, making it impossible to successfully complete the surface quenching process. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a medium-frequency quenching induction device for cone roll processing. It adopts a cone-shaped induction coil, which can better adapt to the shape of the cone roll. It solves the problem that the quenching effect of the small end is not good due to the large gap between the large and small ends of the cone roll caused by conventional induction coils, thereby improving the quality of cone roll quenching and effectively solving the problems in the background art.

[0004] To achieve the aforementioned objective, this utility model adopts the following technical solution: A medium-frequency quenching induction device for tapered roll processing includes a frame, a PLC controller mounted on the side of the frame, a lifting mechanism mounted on the inner side of the frame, an induction coil fixed on the lifting part of the lifting mechanism, the induction coil having a tapered structure, the PLC controller being electrically connected to an external power supply, and the induction coil being electrically connected to the PLC controller.

[0005] Furthermore, the lifting mechanism includes an electric push rod and a lifting seat. The electric push rod is mounted on the top of the frame, and the lifting seat is fixed to the telescopic end of the electric push rod. The electric push rod is electrically connected to a PLC controller.

[0006] Furthermore, the lifting mechanism also includes a slider and a guide rod. The end of the guide rod is fixedly connected to the frame, and the slider is fixed to the side of the lifting seat and slidably connected to the guide rod.

[0007] Furthermore, the lifting mechanism also includes a connecting rod, one end of which is fixedly connected to the lifting seat, and the other end of which is fixedly connected to the induction coil.

[0008] Furthermore, the connecting rod is one of a high-temperature resistant insulating ceramic rod or a glass fiber reinforced polytetrafluoroethylene rod.

[0009] Furthermore, it also includes a positioning groove, which is formed on the base of the frame and positioned directly below the induction coil.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This medium-frequency quenching induction device for cone roll processing has the following advantages: It adopts a cone-shaped induction coil, which can better adapt to the shape of the cone roll, and solves the problem that the quenching effect of the small end is not good due to the large change in the gap between the large and small ends of the cone roll caused by conventional induction coils, thereby improving the quality of cone roll quenching.

[0013] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0014] Please see Figure 1-4 This embodiment provides a technical solution: a medium-frequency quenching induction device for tapered roller processing, including a frame 1, a PLC controller 5 mounted on the side of the frame 1, a lifting mechanism 4 mounted on the inner side of the frame 1, an induction coil 2 fixed on the lifting part of the lifting mechanism 4, the induction coil 2 having a tapered structure, the PLC controller 5 electrically connected to an external power supply, the induction coil 2 electrically connected to the PLC controller 5, the PLC controller 5 controlling the induction coil 2 to work, the induction coil 2 generating an induced magnetic field to quench the tapered roller. The tapered structure of the induction coil 2 can better adapt to the shape of the tapered roller, solving the problem of poor quenching effect at the small end due to the large gap change at the large and small ends of the tapered roller caused by conventional induction coils, thereby improving the quality of tapered roller quenching.

[0015] The lifting mechanism 4 includes an electric push rod 41 and a lifting seat 43. The electric push rod 41 is mounted on the top of the frame 1, and the lifting seat 43 is fixed to the telescopic end of the electric push rod 41. The electric push rod 41 is electrically connected to the PLC controller 5. The lifting mechanism 4 also includes a slider 44 and a guide rod 45. The end of the guide rod 45 is fixedly connected to the frame 1, and the slider 44 is fixed to the side of the lifting seat 43 and slides vertically with the guide rod 45. The lifting mechanism 4 also includes a connecting rod 42. One end of the connecting rod 42 is fixedly connected to the lifting seat 43, and the other end of the connecting rod 42 is fixedly connected to the induction coil 2. The operator starts the device through the PLC controller 5. The controller 5 controls the electric push rod 41 to move. The telescopic end of the electric push rod 41 drives the lifting seat 43 to move up and down. The lifting seat 43 drives the slider 44 to move up and down along the guide rod 45, and then drives the induction coil 2 to rise and fall through the connecting rod 42, thereby adjusting the distance between the induction coil 2 and the cone roller to make it in a suitable position. When the induction coil 2 is raised, it is convenient to place the cone roller. When the induction coil 2 is lowered, it is placed in the working area.

[0016] The connecting rod 42 is either a high-temperature resistant insulating ceramic rod or a glass fiber reinforced polytetrafluoroethylene rod. The selection of a high-temperature resistant insulating material for the connecting rod 42 ensures its normal operation in high-temperature environments and does not interfere with the induction coil 2. The connecting rod 42 can provide a certain degree of support and fixation for the induction coil 2, thereby enhancing the stability of the induction coil 2.

[0017] It also includes a positioning groove 3, which is located on the base of the frame 1 and directly below the induction coil 2. Its function is to position the tapered roller and ensure that the induction coil 2 performs precise quenching on the tapered roller.

[0018] The working principle of the medium-frequency quenching induction device for tapered roller processing provided by this utility model is as follows: First, the tapered roller is placed in the positioning groove 3 to position it so that it is directly below the induction coil 2. The operator starts the device through the PLC controller 5. The PLC controller 5 controls the electric push rod 41 to move. The telescopic end of the electric push rod 41 drives the lifting seat 43 to move up and down. The lifting seat 43 drives the slider 44 to move up and down along the guide rod 45. Then, the connecting rod 42 drives the induction coil 2 to move up and down, thereby adjusting the distance between the induction coil 2 and the tapered roller to a suitable position. After that, the PLC controller 5 controls the induction coil 2 to work. The induction coil 2 generates an induced magnetic field to quench the tapered roller.

[0019] It is worth noting that the components disclosed in the above embodiments are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The working methods of PLC controller 5 controlling induction coil 2 and electric push rod 41 are all based on existing technology. PLC controller 5 and electric push rod 41 are both products currently on the market. Their structures and principles are publicly known technologies. This solution only describes their role in this solution and the technical effects to be produced.
