Description

Technical Field

[0001] The utility model relates to the technical field of medium frequency furnaces, in particular to a medium frequency furnace with a flow-guiding and splash-proof structure. Background Art

[0002] Steel is an alloy composed of iron, carbon, and other elements, and is widely used in construction, machinery manufacturing, transportation, and other fields. Steel can be divided into low-carbon steel, medium-carbon steel, and high-carbon steel depending on its carbon content, and exhibits excellent strength, toughness, and machinability. Steel properties can be optimized through methods such as heat treatment and alloying to meet different engineering requirements. During the production of steel parts, they need to be melted into molten steel, which is done using a medium-frequency furnace. This furnace utilizes a medium-frequency power source to heat metal. Its working principle is to heat the metal through electromagnetic induction, rapidly bringing it to the required temperature for melting or heat treatment.

[0003] However, after the existing medium frequency furnace melts the steel parts, it is necessary to drive the entire medium frequency furnace to rotate through the driving assembly so that the melted liquid is poured out from the top opening of the medium frequency furnace. The lack of a protective structure can easily cause liquid splashing and pose a safety hazard. Moreover, when the liquid is poured directly from the top opening of the medium frequency furnace, since the opening position is fixed, part of the liquid may be retained in the melting chamber of the medium frequency furnace, which is inconvenient to completely divert it out, reducing the practicality of the medium frequency furnace. Therefore, the current medium frequency furnace needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a medium frequency furnace with a diversion and anti-splashing structure to solve the problem raised in the above background technology that the medium frequency furnaces currently on the market pour out the smelted liquid from the top opening of the medium frequency furnace after melting the steel parts, lack of a protective structure, which easily causes liquid splashing and poses a safety hazard, and part of the liquid may be retained in the melting chamber of the medium frequency furnace, making it inconvenient to completely divert it out.

[0012] Preferably, a pushing rack is threadedly sleeved on the outer side of the screw rod, and a placement frame is connected below the pushing rack.

[0013] Preferably, a motor connected to the screw rod through a coupling is installed above the stand, and baffles are movably connected to both ends of the placement frame through a rotating shaft.

[0014] Preferably, an electric push rod is connected between the baffle and the inner wall of the placement frame via a movable shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. A liquid pouring mechanism, a liquid guide groove, a liquid guide frame and a protective cover are provided. By starting the extension and contraction of the hydraulic cylinder, the hydraulic cylinder pushes and pulls the rack to slide left and right in the slide groove. At the same time, the rack and the gear are meshed, so that the rack drives the gear to rotate. Then the gear causes the transmission shaft to drive the smelting cylinder to rotate clockwise or counterclockwise. During the rotation, the smelting cylinder drives the guide block to rotate in the annular groove, and the smelting cylinder drives the liquid outlet to rotate to the position of the liquid guide groove, so that the liquid in the smelting cylinder flows from the liquid guide groove to the liquid guide frame, and then is diverted from the inner wall of the liquid guide frame into the mold.

The pouring mechanism and the protective cover can assist in diversion while preventing liquid splashing, thereby improving the safety and working efficiency of the intermediate frequency furnace.

[0017] 2. A feeding mechanism is provided, which can directly place the steel parts in the placement frame, and then start the motor to drive the screw to rotate. The screw and the pushing rack are threadedly engaged, so that the pushing rack drives the placement frame to move downward on the outside of the screw, and the pushing rack sends the placement frame into the smelting tube. Then the electric push rod extends and pushes the baffle downward, so that one end of the baffle rotates around the rotating shaft to open, making it convenient for the steel parts in the placement frame to fall into the smelting tube. There is no need for staff to send the steel parts into the smelting tube, which improves the convenience of the medium frequency furnace. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In specific implementation, after the existing medium frequency furnace melts the steel parts, it is necessary to drive the entire medium frequency furnace to rotate through the driving assembly so that the smelted liquid is poured out from the top opening of the medium frequency furnace. The lack of a protective structure can easily cause liquid splashing, posing a safety hazard. Moreover, when the liquid is poured directly from the top opening of the medium frequency furnace, since the opening position is fixed, part of the liquid may be retained in the melting chamber of the medium frequency furnace, which is inconvenient to completely divert it out, reducing the practicality of the medium frequency furnace. When the smelted liquid needs to be poured out, the hydraulic cylinder 801 can be activated to extend and retract, so that the hydraulic cylinder 801 pushes and pulls the rack 804 to slide left and right in the slide 805, and at the same time, the rack 804 and the gear 802 are moved. The gear 802 is meshed and connected, so that the rack 804 drives the gear 802 to rotate, and then the gear 802 drives the transmission shaft 803 to drive the smelting cylinder 7 to rotate clockwise or counterclockwise. During the rotation, the smelting cylinder 7 drives the guide block 13 to rotate in the annular groove 15, and the smelting cylinder 7 drives the liquid outlet 14 to rotate to the position of the liquid guide groove 10, so that the liquid in the smelting cylinder 7 flows from the liquid guide groove 10 to the liquid guide frame 11, and then is guided from the inner wall of the liquid guide frame 11 to fall into the mold 3. At the same time, the protective cover 6 blocks the liquid guide frame 11 and blocks the splashing liquid through the inclined inner wall. The pouring mechanism 8 and the protective cover 6 can assist in guiding the liquid while preventing the liquid from splashing, thereby improving the safety and working efficiency of the intermediate frequency furnace.

[0029] See also Figure 1-Figure 3 and Figure 6 A feeding mechanism 5 is connected to one side of the stand 4. The feeding mechanism 5 includes a screw 501, a motor 502, a push rack 503, and a placement frame 504. The screw 501 is installed in the built-in slot of the stand 4 through a bearing. The push rack 503 is threadedly sleeved on the outer side of the screw 501. The placement frame 504 is connected below the push rack 503. The motor 502 is connected to the screw 501 through a coupling above the stand 4. The two ends of the placement frame 504 are movably connected to baffles 18 via rotating shafts 17. An electric push rod 16 is connected between the baffle 18 and the inner wall of the placement frame 504 via a movable shaft. The slot width of the stand 4 matches the width of the push rack 503.

[0030] During specific implementation, since the steel parts need to be manually delivered into the medium frequency furnace, but the temperature in the smelting chamber may be high and not safe, the staff can directly place the steel parts in the placement frame 504, and then start the motor 502 to drive the screw rod 501 to rotate, and the screw rod 501 is threadedly engaged with the pushing rack 503, so that the pushing rack 503 drives the placement frame 504 to move downward on the outside of the screw rod 501, and the pushing rack 503 sends the placement frame 504 into the smelting tube 7, and then the electric push rod 16 extends and pushes the baffle 18 downward, so that one end of the baffle 18 rotates around the rotating shaft 17 to open, so that the steel parts in the placement frame 504 can fall into the smelting tube 7, and the staff does not need to send the steel parts into the smelting tube 7, which improves the convenience of the medium frequency furnace.

[0031] Working principle: When using the medium frequency furnace with a diversion and anti-splashing structure, first place the steel part directly in the placement frame 504, and then feed the steel part into the smelting tube 7 through the feeding mechanism 5. The steel part is melted by heating the smelting tube 7, and the molten liquid is diverted from the smelting tube 7 to the mold 3 through the pouring mechanism 8. At the same time, the liquid guide groove 10, the liquid guide frame 11 and the protective cover 6 guide the liquid and prevent the liquid from splashing, thereby improving the practicality and safety of the medium frequency furnace.
