Description

Technical Field

[0001] This utility model relates to the field of forging heating technology, specifically to a medium-frequency induction heating device for medium-thick plates in forging upper plate. Background Technology

[0002] The upper center plate is a core component of the railway freight car body and bogie connection system. It adopts a flange structure, is installed at the center beam of the car body, and works in conjunction with the lower center plate. It has three core functions: bearing the weight of the car body, transmitting traction / braking force, and enabling steering on curves. When the upper center plate's thick plate is used on the track, it needs to be forged and heated.

[0003] Existing technology cannot uniformly heat the thick plate in the upper center plate, resulting in poor heating effect during forging of the thick plate in the upper center plate. Utility Model Content

An induction coil is arranged on the outer side of the upper center plate and the induction coil rotates to uniformly heat the upper center plate and medium-thick plate.

[0007] Preferably, a drive motor is provided at the upper end of the base, and the output shaft of the drive motor is connected to a drive worm gear, which is mounted in the base through bearings.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] When heating the upper center plate of this invention, the upper center plate is placed on the positioning seat, and the medium-frequency induction heating equipment is started. Based on the principle of electromagnetic induction, when the medium-frequency current passes through the induction coil, an alternating magnetic field is generated around it. When the upper center plate is placed in the alternating magnetic field, eddy currents are generated inside the upper center plate due to electromagnetic induction. According to Joule's law, the eddy currents generate heat under the action of the resistance of the upper center plate itself, thereby rapidly heating the upper center plate to achieve the purpose of heating. At the same time, the drive motor drives the drive worm to rotate, which causes the transmission worm wheel, transmission shaft, mounting plate, medium-frequency induction heating equipment and induction coil to rotate as well. This causes the induction coil to rotate around the upper center plate, thereby uniformly heating the upper center plate and improving the forging heating effect of the upper center plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To address the existing problem of uneven heating of the upper center plate forging of medium-thick plates, resulting in poor heating performance, please refer to [link to relevant documentation]. Figures 1-8 The following technical solution is provided in this embodiment:

[0027] A medium-frequency induction heating device for forging upper center plate medium-thickness plate includes a base 1, an operating table 2 is provided on the base 1, a positioning seat 3 is provided on the operating table 2, and an upper center plate medium-thickness plate 4 is provided on the positioning seat 3, and the positioning seat 3 is used to position the upper center plate medium-thickness plate 4.

[0028] In this embodiment, a drive motor 11 is provided at the upper end of the base 1. The output shaft of the drive motor 11 is connected to a drive worm gear 12. The drive worm gear 12 is mounted in the base 1 through bearings. The drive worm gear 12 meshes with a transmission worm wheel 13. The transmission worm wheel 13 is mounted on a transmission shaft 14. The transmission shaft 14 is mounted on the base 1 through bearings. A mounting plate 15 is provided at one end of the transmission shaft 14 extending to the outside of the base 1. A medium-frequency induction heating device 16 is mounted on the mounting plate 15.

[0029] Specifically, when the drive motor 11 is started, the drive motor 11 drives the drive worm 12 to rotate. Since the drive worm 12 meshes with the transmission worm wheel 13, the drive worm 12 can drive the transmission worm wheel 13, the transmission shaft 14, the mounting plate 15 and the medium frequency induction heating device 16 to rotate as well during the rotation process.

[0030] In this embodiment, the medium-frequency induction heating device 16 is provided with lower connecting plates 161 at both ends. The lower connecting plates 161 are installed on the upper connecting plate 151 by bolts. The upper connecting plate 151 is installed on the mounting plate 15.

[0031] In this embodiment, a guide post 152 is provided on the mounting plate 15, one end of the guide post 152 extends into the base 1, and an annular groove is provided on the base 1 for the guide post 152 to move.

[0032] Specifically, the drive worm gear 12 can drive the mounting plate 15 to rotate during the rotation process. The rotation of the mounting plate 15 is guided by the guide post 152 to ensure the normal operation of the mounting plate 15.

[0033] An induction coil 5 is provided on the outer side of the thick plate 4 in the upper center plate. The induction coil 5 rotates and heats the thick plate 4 in the upper center plate evenly.

[0034] In this embodiment, the medium-frequency induction heating device 16 is provided with a first electrode plate 162 and a second electrode plate 163. One end of the induction coil 5 is connected to the first electrode plate 162, and the other end of the induction coil 5 is connected to the second electrode plate 163.

[0035] Specifically, when the medium-frequency induction heating device 16 is started, based on the principle of electromagnetic induction, when the medium-frequency current passes through the induction coil 5, an alternating magnetic field is generated around it. When the upper center plate 4 is placed in the alternating magnetic field, eddy currents are generated inside the upper center plate 4 due to electromagnetic induction. According to Joule's law, the eddy currents generate heat under the action of the resistance of the upper center plate 4 itself, thereby rapidly heating the upper center plate 4 to achieve the purpose of heating.

[0036] In this embodiment, the induction coil 5 is arranged in a U-shape, with one end of the induction coil 5 located above the middle thick plate 4 of the upper center plate and the other end of the induction coil 5 located below the middle thick plate 4 of the upper center plate.

[0037] Specifically, by placing one end of the induction coil 5 above the middle plate 4 of the upper center plate and the other end of the induction coil 5 below the middle plate 4 of the upper center plate, the middle plate 4 of the upper center plate can be heated by the induction coil 5.

[0038] Working principle: When heating the upper center plate 4, the upper center plate 4 is placed on the positioning seat 3. The positioning seat 3 positions the upper center plate 4 stably. The medium frequency induction heating device 16 is then started. Based on the principle of electromagnetic induction, when the medium frequency current passes through the induction coil 5, an alternating magnetic field is generated around it. When the upper center plate 4 is placed in the alternating magnetic field, eddy currents are generated inside the upper center plate 4 due to electromagnetic induction. According to Joule's law, the eddy currents generate heat under the action of the resistance of the upper center plate 4 itself. This causes the upper center plate 4 to heat up rapidly, achieving the heating purpose. At the same time, the drive motor 11 is started, which drives the drive worm gear 12 to rotate. Since the drive worm gear 12 meshes with the transmission worm wheel 13, the drive worm gear 12 can drive the transmission worm wheel 13, the transmission shaft 14, the mounting plate 15, the medium frequency induction heating device 16, and the induction coil 5 to rotate as well. This causes the induction coil 5 to rotate around the upper center plate 4, thereby uniformly heating the upper center plate 4 and improving the forging heating effect of the upper center plate 4.
