[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 2-Figure 4As shown, an embodiment of the present invention provides: a high-frequency heating furnace with uniform heating, comprising a shell 1, a fixed frame 5 is fixedly connected to the rear end of the shell 1, a motor 6 is fixedly connected to one side of the rear end of the fixed frame 5, and a mounting frame 10 is provided at the driving end of the motor 6 for repeatedly moving the mounting frame 10 up and down, and a linear motor 2 is fixedly connected to the left and right sides of the inner wall of the shell 1 for placing and removing the workpiece, and rotatingly connected to the first gear 7 on the left and right parts of the rear side of the inner wall of the fixed frame 5, and the front end of the first gear 7 is fixedly connected to a half gear 8, and the second gear 18 is meshedly connected to the opposite side of the outer wall of the first gear 7, and the rear end of the second gear 18 is fixedly connected to the driving end of the motor 6, and the outer side of the half gear 8 is meshedly connected to a tooth plate 9, and the rear end of the tooth plate 9 is slidably connected to the rear side of the inner wall of the shell 1, and the front end of the tooth plate 9 is fixedly connected to the rear end of the mounting frame 10, and is slidably connected to the slider 3 on the outer wall of the linear motor 2, and the opposite end of the slider 3 is fixedly connected to the placement frame 4, and the top of the placement frame 4 is fixedly connected to the placement table, and the placement table is directly opposite to the bottom end of the high-frequency heater 17.

[0030] Specifically, refer to Figure 1 A controller is provided at the front end of the shell 1, and the controller is electrically connected to the linear motor 2, the motor 6 and the high-frequency heater 17. When the tooth plate 9 moves to the highest point, it no longer engages with the half gear 8 on the right. On the contrary, when the tooth plate 9 moves to the lowest point, it no longer engages with the half gear 8 on the left. At the same time, when the placement rack 4 moves to the left and moves the workpiece inward, the high-frequency heater 17 can be moved to the highest point to avoid the workpiece from colliding with the high-frequency heater 17. By controlling the motor 6, the high-frequency heater 17 is driven to move up and down to heat the workpiece evenly, ensuring that the workpiece maintains a consistent temperature throughout the heating process, avoiding local overheating or underheating, thereby improving the mechanical properties of the metal such as hardness, strength and toughness, and improving product quality. The working principle of the high-frequency heater 17 is to generate an alternating magnetic field by passing high-frequency alternating current through the induction coil. When the conductive material is placed in this alternating magnetic field, eddy currents are induced inside the material, and the flow of eddy currents inside the material generates heat, thereby heating the material itself.

[0031] Reference Figure 5 and Figure 6As shown, the high-frequency heater 17 has a connecting block 15 fixedly connected to the rear end of the high-frequency heater 17, and a pull rod 11 is provided on the inner and outer walls of the connecting block 15 for installing and disassembling the high-frequency heater 17. The outer wall of the pull rod 11 is slidably connected to the inner wall of the installation frame 10, and the left end of the pull rod 11 is fixedly connected to a clamping block 12. A clamping slot 16 is provided on the inner wall of the connecting block 15, and the outer wall of the clamping block 12 is arranged on the inner wall of the clamping slot 16. The shape of the clamping block 12 matches the clamping slot 16. A tension spring 13 is fixedly connected to the left side of the outer wall of the pull rod 11, and the other end of the tension spring 13 is fixedly connected to the installation frame 10. A protective cover 14 is fixedly connected to the side of the outer wall of the pull rod 11 corresponding to the outer wall of the tension spring 13, and the inner wall of the protective cover 14 is arranged on the outer wall of the tension spring 13.

[0032] Specifically, during installation, first pull the pull rod 11 and insert the connecting block 15 into the installation frame 10. After it is installed in place, release the pull rod 11, and use the elastic force of the tension spring 13 to clamp the card block 12 into the card slot 16, limit the connecting block 15 and the high-frequency heater 17, and complete the installation. At the same time, the protective cover 14 is a heat-insulating material, which can prevent the high-frequency heater 17 from affecting the performance of the tension spring 13 when in use. The high-frequency heater 17 can be removed by pulling the pull rod 11 to the right, so that the operator can handle the equipment more easily during maintenance or overhaul, reduce the risk of safety accidents, and improve the overall performance and reliability of the equipment.

[0033] Working principle: First, the linear motor 2 is started by the controller to drive the slider 3 of the outer wall and the placement rack 4 to slide to the right, and then the workpiece is placed on the placement table. The placement rack 4 is then slid to the left by the linear motor 2, and the workpiece is placed on the lower side of the high-frequency heater 17. The motor 6 and the high-frequency heater 17 are then started by the controller. The motor 6 drives the second gear 18 to rotate, and the second gear 18 drives the first gears 7 on both sides of the outer wall to rotate clockwise in the same direction. The first gear 7 drives the half gear 8 to rotate. When the tooth plate 9 moves to the highest point, the half gear 8 on the left engages with the tooth plate 9 and drives the tooth plate 9 to move downward. When the tooth plate 9 moves to the bottom, the half gear 8 on the left is no longer engaged with the tooth plate 9, and the half gear 8 on the right will engage with the tooth plate 9 and drive the tooth plate 9 to move upward, thereby driving the tooth plate 9 to move up and down repeatedly, and the tooth plate 9 drives the mounting frame 10 and the high-frequency heater 17 to move up and down to heat the workpiece evenly. At the same time, when the high-frequency heater 17 needs to be disassembled, first slide the placement frame 4 to the right through the controller, and then pull the pull rod 11 to the right. The pull rod 11 drives the block 12 to move, and the block 12 is removed from the slot 16. The high-frequency heater 17 can be taken out upward to complete the disassembly.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
