Description
Technical Field
[0001] This utility model relates to the field of melting furnace technology, specifically a novel high-frequency induction melting furnace. Background Technology
[0002] A high-frequency induction melting furnace is a type of induction furnace. The higher the frequency, the lower the heat penetration. High-frequency induction heating is suitable for melting precious metals. It is widely used in processes such as melting, refining, and casting after placing precious metals such as gold, silver, and platinum into a crucible and instantly inducing heating.
[0003] Most existing high-frequency induction melting furnaces use a motor to drive the furnace body to tilt materials. The motor bears the force of the tilting force on the furnace body and the materials inside, resulting in a short lifespan for the motor. Existing patent application number CN202321706817.1 discloses a high-frequency induction melting furnace that uses hydraulic thrust from a first hydraulic cylinder to tilt the furnace body and hydraulic thrust from a second hydraulic cylinder to move the support arm up and down, detaching the stirring device from the furnace body for easier material loading and unloading. Furthermore, hydraulic cylinders can withstand a greater load than motors, significantly improving the performance of the high-frequency induction melting furnace. However, this method requires multiple hydraulic cylinders to assist the motor, which, while facilitating material handling, consumes a lot of energy and has low utilization. To address this issue, we propose a novel high-frequency induction melting furnace. Utility Model Content

The telescopic section is movably inserted into the fixed section. The rack and pinion are slidably connected to the support frame. The telescopic section and rack and pinion of the second telescopic member are fixed. The fixed section of the second telescopic member is hinged to the support frame. The rack and pinion are meshed with a gear. The telescopic section of the first telescopic member is hinged to the furnace body.

[0007] A lifting mechanism is provided above the mounting base. The lifting mechanism includes a motor and a lifting plate. A transmission screw is provided on the output shaft of the motor. The transmission screw is threadedly connected to the lifting plate. Guide rods are provided on both sides of the transmission screw.

[0008] The stirring mechanism includes a second motor and a stirring shaft. The stirring shaft is located on the output shaft of the second motor, and the second motor is fixedly mounted on the lifting plate.
[0009] The blowing mechanism includes a blowing cylinder and a connecting rod. The connecting rod is movably inserted into the blowing cylinder and fixed to the lifting plate. The blowing cylinder is fixedly installed on the mounting base. The blowing cylinder is provided with an air intake pipe and an air exhaust pipe.

[0010] Preferably, the center lines of the drive screw, the plug rod, and the stirring shaft are all parallel to each other, and the length of the drive screw is greater than the length of the stirring shaft and the plug rod.
[0011] Preferably, the first telescopic member is located in the middle right part of the furnace body, and the first telescopic member is located between the mounting base and the furnace body.

[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This new type of high-frequency induction melting furnace, by setting a booster mechanism on the right side of the furnace body, after the motor three starts working, the drive shaft rotates, which in turn drives the furnace body, driven shaft and gear to rotate. Through the meshing of the gear and rack, the rack moves back and forth on the support frame. When the rack moves to the right, it can blow the gas inside the second telescopic member into the first telescopic member. At this time, the gas inside the first telescopic member increases, and the telescopic section of the first telescopic member extends out from the fixed section. At this time, the furnace body can be tilted with the help of the first telescopic member, which can disperse the force on the motor three and further ensure the performance of the motor three. Moreover, the support of the triangular fulcrum distribution can improve the material feeding stability of the furnace body.
[0018] 2. This novel high-frequency induction melting furnace, by setting up a stirring mechanism and a lifting mechanism, enables the transmission screw to rotate after the motor is turned on. Guided by the guide rod, the top lifting plate moves from top to bottom, which drives the stirring shaft to rotate, thereby causing the stirring teeth on the stirring shaft to stir the material inside the furnace. At the same time, with the help of the lifting force, the movement of the top lifting plate allows the plug rod to be continuously inserted and withdrawn into the blower, thereby allowing the gas inside the blower to be discharged to the outside through the exhaust pipe, which can dissipate heat from motor one and motor two, further ensuring the service life of the motors. When the plug rod is withdrawn from the blower, external gas can be drawn into the blower from the suction pipe, thereby realizing air exchange and further facilitating the heat dissipation of the motor.
[0019] In summary, this solution not only facilitates the feeding operation of induction melting, but also has a high utilization rate, making it worthy of widespread adoption. Attached Figure Description

[0027] 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.
[0028] Example: Please refer to Figure 1-6 This utility model provides a technical solution: a novel high-frequency induction melting furnace, comprising a mounting base 1, a support frame 2, a first telescopic member 7, and a furnace body 4. The mounting base 1 and the support frame 2 are centrally aligned, wherein the support frame 2 supports the furnace body 4, and the first telescopic member 7 is located at the right middle part of the furnace body 4, and is positioned between the mounting base 1 and the furnace body 4. The lower ends of the mounting base 1 and the support frame 2 are flush, and the mounting base 1 and the support frame 2 are fixedly connected.
[0029] Please see Figure 1-3 A driven shaft 84 and a driving shaft 87 are rotatably connected to the front and rear sides of the upper end of the mounting base 1, respectively. Both the driven shaft 84 and the driving shaft 87 are fixedly installed to the furnace body 4. A motor 86 is provided at the outer end of the driving shaft 87. The motor 86 is fixedly installed on the support frame 2. The motor 86 is connected to the control switch through a wire. The centers of the driving shaft 87 and the driven shaft 84 are collinear. A gear 83 is fixedly installed at the outer end of the driven shaft 84. A booster mechanism 8 is provided below the gear 83. When the motor 86 is turned on, it can make the driving shaft 87 rotate, thereby driving the furnace body 4 and the driven shaft 84 to rotate. After the driven shaft 84 rotates, the gear 83 rotates.
[0030] Please see Figure 1 and Figure 5 The booster mechanism 8 includes a second telescopic member 81 and a rack and pinion 82.
[0031] The first telescopic member 7 and the second telescopic member 81 each include a telescopic section and a fixed section. The telescopic section is movably inserted into the fixed section. The telescopic section of the first telescopic member 7 is hinged to the furnace body 4. The fixed section of the first telescopic member 7 and the fixed section of the second telescopic member 81 are connected through a connecting pipe 85. The rack 82 is slidably connected to the support frame 2. The telescopic section of the second telescopic member 81 and the rack 82 are fixed. The fixed section of the second telescopic member 81 is hinged to the support frame 2. The rack 82 and the gear 83 are meshed. After the driven shaft 84 rotates clockwise, the gear 83 can rotate clockwise. Through the meshing action of the gear 83 and the rack 82, the rack 82 moves back and forth on the support frame 2. When the rack 82 moves to the left, it can draw the gas inside the first telescopic member 7 into the second telescopic member 81. At this time, the gas inside the first telescopic member 7 decreases, and the telescopic section of the first telescopic member 7 retracts into the fixed section. This state is the initial state after the furnace body 4 is tilted.
[0032] Please see Figure 2 and Figure 5 The second telescopic member 81 is located below the driven shaft 84, and the center line of the second telescopic member 81 is perpendicular to the center line of the driven shaft 84.
[0033] In this example, a lifting mechanism 3 is provided above the mounting base 1. The lifting mechanism 3 includes a motor 31 and a lifting plate 33. A transmission screw 32 is provided on the output shaft of the motor 31. The transmission screw 32 and the lifting plate 33 are threadedly connected. Guide rods 34 are provided on both sides of the transmission screw 32. The upper end of the guide rod 34 is fixedly connected to the lifting plate 33, and the guide rod 34 is movably inserted into the mounting base 1. A stirring mechanism 5 and a blowing mechanism 6 are arranged sequentially from left to right on the lifting plate 33. After the motor 31 is turned on, the transmission screw 32 can rotate. Through the guiding action of the guide rod 34, the lifting plate 33 moves from bottom to top, which can drive the stirring mechanism 5 to move upward. Thus, before the furnace body 4 begins to tilt, the stirring mechanism 5 is disengaged from the furnace body 4. Similarly, by operating in the opposite way, the stirring mechanism 5 can be inserted into the furnace body 4 to realize the stirring operation of the material inside the furnace body 4.
[0034] Furthermore, the stirring mechanism 5 includes a second motor 51 and a stirring shaft 52. The stirring shaft 52 is mounted on the output shaft of the second motor 51, and the second motor 51 is fixedly mounted on the lifting plate 33. The stirring shaft 52 is collinear with the center of the furnace body 4, and multiple stirring teeth are provided on the stirring shaft 52. After the second motor 51 is turned on, the second motor 51 can drive the stirring shaft 52 to rotate, thereby causing the stirring teeth on the stirring shaft 52 to stir the material inside the furnace body 4.
[0035] Furthermore, the blowing mechanism 6 includes a blowing cylinder 61 and a connecting rod 64. The connecting rod 64 is movably inserted into the blowing cylinder 61 and fixed to the lifting plate 33. The center lines of the transmission screw 32, the connecting rod 64, and the stirring shaft 52 are all parallel to each other, and the length of the transmission screw 32 is greater than the length of the stirring shaft 52 and the connecting rod 64. The blowing cylinder 61 is fixedly installed on the mounting base 1. The blowing cylinder 61 is provided with an air intake pipe 62 and an exhaust pipe 63. Both the air intake pipe 62 and the exhaust pipe 63 are connected to the inside of the blowing cylinder 61, and both the air intake pipe 62 and the exhaust pipe 63 are provided with one-way valves. The exhaust port of the exhaust pipe 63 faces the motor 1 31 and the motor 2 51. A notch is provided on the side of the furnace body 4 facing away from the mounting base 1, located in the left middle part of the furnace body 4. When the motor 1 31 drives the transmission screw 32 to rotate, the lifting plate 33 moves upward or downward through the action of the guide rod 34. When the lifting plate 33 moves upward, the one-way valve on the suction pipe 62 on the lifting plate 33 opens, allowing external gas to be drawn in through the suction pipe 62; when the lifting plate 33 moves downward, the one-way valve on the suction pipe 62 closes, and the one-way valve on the exhaust pipe 63 opens, allowing the gas inside the blow-jet cylinder 61 to be blown into the motor through the exhaust pipe 63, which can dissipate heat from the motor and further ensure the motor's performance.
[0036] Working principle: This new type of high-frequency induction melting furnace, during use, the furnace body 4 as... Figure 1 As shown, when motor 31 rotates in the forward direction, the transmission screw 32 rotates. Guided by the guide rod 34, the lifting plate 33 moves from top to bottom, thereby driving the stirring mechanism 5 to be placed inside the furnace body 4, where it can stir the material inside the furnace body 4. After stirring is complete, motor 31 rotates in the reverse direction, causing the lifting plate 33 to move from bottom to top, removing the stirring mechanism 5 from inside the furnace body 4. When the furnace body 4 is tilted, motor 86 rotates in the forward direction, causing the drive shaft 87 to rotate, thereby driving the furnace body 4 and the driven shaft 84 to rotate, realizing the tilting of the furnace body 4 to the left. During this process, from... The rotating shaft 84 rotates, and the gear 83 rotates. Through the meshing action of the gear 83 and the rack 82, the rack 82 moves back and forth on the support frame 2. When the rack 82 moves to the right, it can blow the gas inside the second telescopic member 81 into the first telescopic member 7. At this time, the gas inside the first telescopic member 7 increases, and the telescopic section of the first telescopic member 7 extends out from the fixed section. At this time, the first telescopic member 7 can assist in tilting the furnace body 4, which can disperse the force on the motor 3 86 and further ensure the performance of the motor 3 86. Moreover, the triangular fulcrum distribution of the support can improve the material feeding stability of the furnace body 4.
