Description

Technical Field

[0001] This utility model relates to the field of medium-frequency induction furnace technology, specifically to a feeding device for a medium-frequency induction furnace. Background Technology

[0002] A medium-frequency induction furnace is an industrial electric furnace that uses the principle of electromagnetic induction to heat and melt metals. Its operating frequency is typically between 150Hz and 10kHz (medium frequency range). It generates eddy currents in the metal charge through an alternating magnetic field, causing the metal to heat up and melt. This equipment has advantages such as rapid heating, high thermal efficiency, precise temperature control, and energy saving. It is widely used in industries such as steel, casting, and non-ferrous metals, and is suitable for melting metals such as steel, iron, copper, and aluminum. Compared to traditional coal-fired or resistance furnaces, medium-frequency induction furnaces have a higher degree of automation and less oxidation loss, but they require a frequency converter and cooling system, and have higher requirements for processes such as feeding and furnace lining.

[0003] Currently, traditional medium-frequency induction furnace feeding devices mostly adopt inclined or vibrating feeding methods to put metal furnace materials (such as scrap steel, alloys, etc.) into the molten pool from the furnace opening. However, when cold furnace materials are directly put into the high-temperature molten pool, due to the drastic temperature difference, the molten metal is prone to violent splashing, which not only causes metal loss, but may also endanger the safety of operators and pollute the equipment and environment. In order to solve the above problems, the inventors have proposed a feeding device for medium-frequency induction furnace. Utility Model Content

[0004] In order to solve the problem that molten material splashing during feeding of medium-frequency induction furnaces can easily cause injury, the purpose of this utility model is to provide a feeding device for medium-frequency induction furnaces.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a feeding device for a medium-frequency induction furnace, comprising a worktable, an induction furnace body fixedly installed on the top of the worktable, two symmetrically distributed vertical plates fixedly connected to one side of the worktable, a feeding cylinder arranged between the two vertical plates, a guide assembly arranged between the feeding cylinder and the vertical plates, slide rails fixedly connected to the top of the worktable and on both sides of the induction furnace body, two symmetrically distributed sliding plates slidably engaging the top of the slide rails, a protective cover fixedly connected to the top of each sliding plate, and a linkage assembly arranged between the protective cover and the vertical plate.

[0006] Preferably, the guide assembly includes two fixed plates, which are fixedly connected to one side of the top and bottom of the vertical plate. A sliding rod is fixedly connected between the two fixed plates. A slider is slidably engaged on the outer side of each sliding rod. A rotating rod is rotatably connected to the side of each slider near the vertical plate. A roller is rotatably connected to the end of each rotating rod away from the rotating shaft. The roller is movably engaged in a guide groove. The end of the rotating shaft away from the vertical plate extends to one side of the slider and is rotatably connected to the feeding cylinder. A threaded rod is rotatably connected to one side of one of the vertical plates. The slider is threadedly connected to the outer side of the threaded rod. A stepper motor is fixedly installed at the top of the fixed plate. The drive end of the stepper motor is fixedly connected to the threaded rod.

[0007] Preferably, the linkage component includes a connecting rod, which is fixedly connected to one side of the slider. A guide rod is fixedly connected to the end of the connecting rod away from the slider. A guide groove is provided on each guide rod. A fixing rod is fixedly connected to the side of the slide plate near the vertical plate. A roller is rotatably connected to the end of the fixing rod away from the slide plate. The roller is movably engaged in the guide groove.

[0008] Preferably, the length of the horizontal side of the second inclined section of the guide groove is equal to half the distance between the two protective covers.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. During feeding, the connecting rod moves upward along with the slider, and at the same time drives the connecting rod, guide rod and guide groove two to move synchronously. The guide groove two drives the roller two, and at the same time drives the slide plate and protective cover to move symmetrically along the top of the slide rail to the side that is closer to each other, so as to close the protective cover. This facilitates accurate feeding and prevents molten metal from splashing onto the outside of the device, further ensuring the personal safety of the operators.

[0011] 2. The stepper motor drives the threaded rod to rotate, which in turn drives the slider to move upward along the outside of the slider and the roller to move along the inside of the guide groove. The guide groove guides the movement of the roller. When the roller moves from the vertical section to the inclined section of the guide groove, it drives the rotating rod to rotate relative to the slider, thereby driving the feeding cylinder to rotate to one side of the induction furnace body, realizing automatic feeding operation.

[0018] 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.

[0019] Example: Figure 1-4 As shown, this utility model provides a feeding device for a medium-frequency induction furnace, including a workbench 1. An induction furnace body 2 is fixedly installed on the top of the workbench 1. Two symmetrically distributed vertical plates 3 are fixedly connected to one side of the workbench 1. A feeding cylinder 4 is arranged between the two vertical plates 3. A guide component 5 is arranged between the feeding cylinder 4 and the vertical plates 3. Slide rails 6 are fixedly connected to the top of the workbench 1 and on both sides of the induction furnace body 2. Two symmetrically distributed sliding plates 7 are slidably engaged at the top of the slide rails 6. A protective cover 8 is fixedly connected to the top of each sliding plate 7. A linkage component 9 is arranged between the protective cover 8 and the vertical plate 3.

[0020] The guide assembly 5 includes two fixed plates 51, which are fixedly connected to one side of the top and bottom of the vertical plate 3. A slide rod 52 is fixedly connected between the two fixed plates 51. A slider 53 is slidably engaged on the outer side of the slide rod 52. A rotating rod 54 is rotatably connected to the side of the slider 53 near the vertical plate 3. A roller 55 is rotatably connected to the end of the rotating rod 54 away from the rotating shaft. The roller 55 is movably engaged in the guide groove 56. The end of the rotating shaft of the rotating rod 54 away from the vertical plate 3 extends to one side of the slider 53 and is rotatably connected to the feeding cylinder 4.

[0021] By adopting the above technical solution, when the slider 53 moves vertically along the outside of the slide bar 52, it simultaneously drives the roller 55 to move along the inside of the guide groove 56. The guide groove 56 guides the movement of the roller 55. When the roller 55 moves from the vertical section of the guide groove 56 to the inside of the inclined section, it drives the rotating rod 54 to rotate relative to the slider 53, thereby driving the feeding cylinder 4 to rotate and realizing the material pouring operation.

[0022] The linkage component 9 includes a connecting rod 91, which is fixedly connected to one side of the slider 53. The end of the connecting rod 91 away from the slider 53 is fixedly connected to a guide rod 92. The guide rod 92 is provided with a guide groove 93. The side of the slide plate 7 near the vertical plate 3 is fixedly connected to a fixing rod 94. The end of the fixing rod 94 away from the slide plate 7 is rotatably connected to a roller 95. The roller 95 is movably engaged in the guide groove 93.

[0023] By adopting the above technical solution, when the slider 53 moves vertically, it drives the connecting rod 91, the guide rod 92 and the second guide groove 93 to move synchronously. The second guide groove 93 drives the second roller 95, and at the same time drives the slide plate 7 and the protective cover 8 to move laterally symmetrically along the top of the slide rail 6, so as to realize the opening and closing of the protective cover 8. When pouring material, the protective cover 8 is closed, which facilitates accurate material feeding and prevents molten metal from splashing onto the outside of the device, thereby improving the safety of the operation.

[0024] One of the vertical plates 3 is rotatably connected to a threaded rod 57 on one side, and a slider 53 is threadedly connected to the outside of the threaded rod 57. A stepper motor 58 is fixedly installed on the top of the fixed plate 51, and the drive end of the stepper motor 58 is fixedly connected to the threaded rod 57.

[0025] By adopting the above technical solution, the stepper motor 58 drives the threaded rod 57 to rotate, and at the same time drives the slider 53 to move vertically along the outside of the threaded rod 57, thereby realizing the driving of the equipment.

[0026] The length of the horizontal side of the inclined section of guide groove 293 is equal to half the distance between the two protective covers 8.

[0027] By adopting the above technical solution, and by setting the length of the horizontal side of the inclined section of the guide groove 2 93 to be equal to half the distance between the two protective covers 8, the accurate closure between the two protective covers 8 can be guaranteed.

[0028] Working principle: When feeding the medium-frequency induction furnace, the stepper motor 58 drives the threaded rod 57 to rotate, which in turn drives the slider 53 to move upward along the outside of the slide rod 52, and drives the roller 55 to move along the inside of the guide groove 56. The guide groove 56 guides the movement of the roller 55. When the roller 55 moves from the vertical section of the guide groove 56 to the inside of the inclined section, it drives the rotating rod 54 to rotate relative to the slider 53, thereby driving the feeding cylinder 4 to rotate to one side of the induction furnace body 2 to realize the unloading operation.

[0029] At the same time, when the slider 53 moves upward, it drives the connecting rod 91, the guide rod 92 and the second guide groove 93 to move synchronously. The second guide groove 93 drives the second roller 95, and at the same time drives the slide plate 7 and the protective cover 8 to move symmetrically along the top of the slide rail 6 to the side that are closer to each other. This closes the protective cover 8, which facilitates accurate material feeding and prevents molten metal from splashing onto the outside of the device, thus improving the safety of the operation.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
