Technical Field

[0001] This utility model relates to the field of casting and smelting furnace technology, specifically a fixed-point casting structure for a medium-frequency furnace. Background Technology

[0002] With the continuous development of the domestic metal casting industry, many casting companies have also raised their requirements for product quality. After the metal is melted in the medium frequency induction melting casting furnace, the operator controls the tilt of the furnace body to pour the molten metal into the mold, or first pours it into the tundish and then pours it into the mold through the tundish.

[0003] For example, CN215373480U discloses a fixed-point casting medium-frequency induction furnace, which relates to the technical field of furnace body devices. It includes a frame, a furnace body support hinged to the frame, and a casting furnace fixed to the furnace body support. The casting furnace is fixed to the furnace body support via a cam handle. Several silicon steel sheets are arranged around the outer wall of the casting furnace, extending along the axial direction of the casting furnace. This invention solves the problems of magnetic field leakage in traditional devices, which affects people and equipment in the surrounding environment; the difficulty in quick disassembly due to the connection structure during furnace body disassembly and maintenance; and the inability to cast molten iron at a fixed point, affecting the stability of the casting process.

[0004] However, in actual use, the above technology uses hydraulic cylinders to drive the medium-frequency furnace for casting, which has problems such as complicated wiring and easy damage to the pipeline due to high temperature. Utility Model Content

[0005] The purpose of this utility model is to provide a fixed-point casting structure for medium-frequency furnaces to solve the problems of complicated wiring and easy damage to pipelines caused by high temperatures.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixed-point casting structure for a medium-frequency furnace, comprising:

[0007] The base has a support frame fixedly mounted on its top. A drive frame is hinged to the top of the support frame. An mounting frame is detachably mounted on the top of the drive frame. A medium-frequency furnace is fixedly embedded in the middle of the mounting frame. A casting nozzle is fixedly mounted at one end of the top of the medium-frequency furnace.

[0008] A support arm is hinged to the middle of the drive frame. The hinge position of the drive frame and the support arm is staggered with the hinge position of the drive frame and the support frame, so that when the support arm moves, the drive frame rotates around the hinge point with the support frame. A first slide is hinged to the bottom of the support arm. A lead screw sleeve is fixedly connected to the middle of the top of the first slide. A lead screw is threaded to the middle of the lead screw sleeve, so that when the lead screw rotates, it drives the lead screw sleeve to move linearly. A first slide rail is movably connected to the bottom of the first slide and is fixedly connected to the top of the base.

[0009] Preferably, the two ends of the lead screw are rotatably connected to fixed seats via bearings, and the fixed seats are fixedly connected to the top of the base. One end of the opposite face of each of the two fixed seats is fixedly connected to a guide rod. A first guide sleeve is movably sleeved on the surface of the guide rod, and the first guide sleeve is fixedly connected to the top of the first slide. The lead screw is driven by a drive motor.

[0010] Preferably, a fixing post is fixedly embedded in the middle of the mounting bracket, and a hanging lug is fixedly connected to the top of the fixing post.

[0011] Preferably, a mounting plate is fixedly connected to the inner wall of the drive frame corresponding to the fixed column position. A hinge seat is fixedly connected to one end of the bottom of the mounting plate. A first hinge arm is hinged to the middle of the hinge seat. A second hinge arm is hinged to the end of the first hinge arm away from the hinge position of the hinge seat. A hinge handle is hinged to the inner wall of the second hinge arm, and the hinge axis of the inner wall of the second hinge arm is clearance-fitted with the hinge handle. The hinge handle has an L-shaped structure and is hinged to the middle of the hinge seat. A drive column is hinged to the end of the second hinge arm away from the hinge handle position. A second guide sleeve is movably sleeved on the surface of the drive column, and the second guide sleeve is fixedly connected to the middle of the hinge seat, so that when the hinge handle is hinged to the hinge seat, it cooperates with the second hinge arm to drive the drive column to move linearly on the inner wall of the second guide sleeve.

[0012] Preferably, a first connecting seat is fixedly connected to the end of the drive column away from the hinge seat, a connecting arm is fixedly connected to the surface of the first connecting seat, a second connecting seat is fixedly connected to the end of the connecting arm away from the first connecting seat, and a positioning column is fixedly connected to the end of the second connecting seat corresponding to the position of the first connecting seat. A support tube is fixedly embedded in the middle of the mounting plate corresponding to the position of the positioning column. The positioning column movably passes through the drive frame and is movably inserted into the inner wall of the support tube. Positioning holes are respectively opened on the side walls of the positioning column and the support tube corresponding to the position of the positioning column, and the positioning column is movably connected to the inner wall of the positioning hole.

[0013] Preferably, the top of the first connecting seat and the top of the second connecting seat are respectively fixedly connected to the second slide block, the surface of the second slide block is movably connected to the second slide rail, and the second slide rail is fixedly connected to the bottom of the mounting plate.

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

[0015] This utility model uses a drive motor to drive the lead screw to rotate, and the lead screw, together with the lead screw sleeve, drives the first slide to move linearly. The first slide, through the support arm, causes the drive frame and the support frame to hinge together. The drive frame, through the mounting frame, causes the intermediate frequency furnace to hinge together with the support frame, and the intermediate frequency furnace to tilt at a fixed point. The molten metal in the intermediate frequency furnace is poured out through the pouring nozzle, thereby achieving the purpose of completing the pouring work without laying pipelines.

[0016] This invention also involves rotating the hinge handle upwards, causing it to hinge with the hinge seat. This hinges the second hinge arm to hinge with the first hinge arm and the drive column, respectively. The second hinge arm then moves the drive column away from the hinge seat. As the drive column moves away from the hinge seat, it causes the first connecting seat, the connecting arm, and the second connecting seat to move away from the hinge seat. This allows the second connecting seat to move the positioning column out of the positioning hole on the side wall of the fixed column and the support tube. At this point, the fixed column is no longer constrained within the support tube, meaning it is no longer constrained by the positioning column. By using the lugs in conjunction with a crane, the mounting frame and the intermediate frequency furnace can be moved from the top of the drive frame, facilitating the disassembly of the mounting frame and the intermediate frequency furnace.

[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] Please see Figure 1-7 This utility model provides a technical solution: a fixed-point casting structure for a medium-frequency furnace, comprising:

[0027] The base 1 has a support frame 2 fixedly installed on its top. The support frame 2 has a drive frame 3 hinged to its top. The drive frame 3 has a mounting frame 4 detachably installed on its top. The mounting frame 4 has a medium frequency furnace 5 fixedly embedded in its middle. The top end of the medium frequency furnace 5 has a pouring nozzle 6 fixedly installed.

[0028] A support arm 7 is hinged to the middle of the drive frame 3. The hinge position of the drive frame 3 and the support arm 7 is staggered with the hinge position of the drive frame 3 and the support frame 2, so that when the support arm 7 moves, the drive frame 3 rotates around the hinge point with the support frame 2. A first slide block 8 is hinged to the bottom of the support arm 7. A lead screw sleeve 9 is fixedly installed in the middle of the top of the first slide block 8. A lead screw 10 is threadedly connected to the middle of the lead screw sleeve 9, so that when the lead screw 10 rotates, it drives the lead screw sleeve 9 to move linearly. A first slide rail 11 is movably connected to the bottom of the first slide block 8, and the first slide rail 11 is fixedly installed on the top of the base 1. The two ends of the lead screw 10 are... A fixed seat 12 is rotatably connected by a bearing, and the fixed seat 12 is fixedly installed on the top of the base 1. A guide rod 13 is fixedly installed on one end of the opposite face of the two fixed seats 12. A first guide sleeve 14 is movably sleeved on the surface of the guide rod 13, and the first guide sleeve 14 is fixedly installed on the top of the first slide block 8. By setting the first slide block 8 in conjunction with the first slide rail 11, the guide rod 13 and the first guide sleeve 14, the movement of the first slide block 8 is guided, so that the first slide block 8 can stably drive the support arm 7 to move, thereby improving the accuracy of the pouring nozzle 6 during pouring. The lead screw 10 is driven by a drive motor.

[0029] When the above structure is in use, the drive motor drives the lead screw 10 to rotate, and the lead screw 10 drives the lead screw sleeve 9 to move in conjunction with the first slide block 8. This causes the first slide block 8 to engage with the support arm 7, which in turn causes the drive frame 3 to hinge with the support frame 2. The drive frame 3 then drives the intermediate frequency furnace 5 to hinge with the support frame 2 via the mounting frame 4, causing the intermediate frequency furnace 5 to tilt at a fixed point. The molten metal inside the intermediate frequency furnace 5 is poured out through the pouring nozzle 6, thereby achieving the purpose of completing the pouring work without the need for piping.

[0030] A fixing post 15 is fixedly embedded in the middle of the mounting bracket 4. A hanging lug 16 is fixedly installed on the top of the fixing post 15. A mounting plate 17 is fixedly installed on the inner wall of the drive frame 3 corresponding to the position of the fixing post 15. A hinge seat 18 is fixedly installed at one end of the bottom of the mounting plate 17. A first hinge arm 19 is hinged to the middle of the hinge seat 18. A second hinge arm 21 is hinged to the end of the first hinge arm 19 away from the hinge position of the hinge seat 18. A hinge handle 20 is hinged to the inner wall of the second hinge arm 21, and the hinge shaft of the inner wall of the second hinge arm 21 is clearance-fitted with the hinge handle 20. The hinge handle 20 has an L-shaped structure and is hinged to the middle of the hinge seat 18. A drive post 22 is hinged to the end of the second hinge arm 21 away from the position of the hinge handle 20. A second guide sleeve 23 is movably sleeved on the surface of the drive post 22, and the second guide sleeve 23 is fixedly installed on the hinge seat 18. In the middle, when the hinge handle 20 is hinged to the hinge seat 18, the second hinge arm 21 drives the drive column 22 to move linearly on the inner wall of the second guide sleeve 23. The end of the drive column 22 away from the hinge seat 18 is fixedly installed with a first connecting seat 24. The surface of the first connecting seat 24 is fixedly installed with a connecting arm 25. The end of the connecting arm 25 away from the first connecting seat 24 is fixedly installed with a second connecting seat 26. The end of the second connecting seat 26 corresponding to the position of the first connecting seat 24 is fixedly installed with a positioning column 27. The middle part of the mounting plate 17 corresponding to the position of the fixed column 15 is fixedly embedded with a support tube 28. The fixed column 15 movably passes through the drive frame 3 and is movably inserted into the inner wall of the support tube 28. The side walls of the fixed column 15 and the support tube 28 corresponding to the position of the positioning column 27 are respectively provided with positioning holes 29, and the positioning column 27 is movably connected to the inner wall of the positioning hole 29.

[0031] When the above structure is in use, by rotating the hinge handle 20 upward, the hinge handle 20 is hinged to the hinge seat 18, and the second hinge arm 21 is hinged to the drive column 22. Under the guidance of the second guide sleeve 23, the drive column 22 moves away from the hinge seat 18, and the drive column 22 drives the first connecting seat 24, the connecting arm 25 and the second connecting seat 26 to move away from the hinge seat 18. This causes the second connecting seat 26 to move the positioning column 27 out of the positioning hole 29 on the side wall of the fixed column 15 and the support tube 28. At this time, the fixed column 15 is no longer constrained in the support tube 28, that is, the fixed column 15 is no longer constrained by the positioning column 27. At this time, the mounting bracket 4 and the medium frequency furnace 5 can be moved out from the top of the drive frame 3 by using the hanging ear 16 in conjunction with the crane, so as to facilitate the disassembly of the mounting bracket 4 and the medium frequency furnace 5.

[0032] The top of the first connecting seat 24 and the second connecting seat 26 are respectively fixedly installed with a second slide 30. The surface of the second slide 30 is movably connected with a second slide rail 31, and the second slide rail 31 is fixedly installed at the bottom of the mounting plate 17. By setting the second slide 30 and the second slide rail 31, the second connecting seat 26 and the first connecting seat 24 can move in a stable linear motion, thereby improving the accuracy of the insertion between the positioning post 27 and the positioning hole 29.

[0033] Working principle: In use, this utility model drives the lead screw 10 to rotate via a drive motor, which in turn drives the lead screw sleeve 9 to move linearly along the direction of the lead screw 10. This causes the lead screw sleeve 9 to drive the first slide block 8 to move linearly on the first slide rail 11. When the first slide block 8 moves, it causes the support arm 7 to move, which in turn causes the support arm 7 to hinge between the drive frame 3 and the support frame 2. The drive frame 3 then drives the intermediate frequency furnace 5 to hinge with the support frame 2 via the mounting frame 4, causing the intermediate frequency furnace 5 to tilt at a fixed point. The molten metal inside the intermediate frequency furnace 5 is poured through the pouring nozzle 6, thus achieving the purpose of completing the pouring work without laying pipelines. By setting the first slide block 8 in conjunction with the first slide rail 11, the guide rod 13, and the first guide sleeve 14 to guide the movement of the first slide block 8, the first slide block 8 can stably drive the support arm 7 to move, thereby improving the accuracy of pouring when pouring through the pouring nozzle 6.

[0034] When the intermediate frequency furnace 5 needs to be replaced or repaired, the hinge handle 20 is rotated upwards, and the hinge handle 20 is hinged to the hinge seat 18. This causes the second hinge arm 21 to be hinged to the first hinge arm 19 and the drive column 22 respectively. The second hinge arm 21 then drives the drive column 22 to move away from the hinge seat 18. When the drive column 22 moves away from the hinge seat 18, it causes the first connecting seat 24, the connecting arm 25, and the second connecting seat 26 to move away from the hinge seat 18. This causes the second connecting seat 26 to move the positioning column 27 out of the positioning hole 29 on the side wall of the fixed column 15 and the support tube 28. At this time, the fixed column 15 is no longer constrained in the support tube 28, that is, the fixed column 15 is no longer constrained by the positioning column 27. At this time, the mounting frame 4 and the intermediate frequency furnace 5 can be moved out from the top of the drive frame 3 by using the hanging lug 16 in conjunction with the crane, so as to facilitate the disassembly of the mounting frame 4 and the intermediate frequency furnace 5.

[0035] When it is necessary to install the mounting bracket 4 and the intermediate frequency furnace 5 with the drive frame 3, align the fixed column 15 with the corresponding support tube 28 position of the drive frame 3, and insert the fixed column 15 into the inner wall of the support tube 28. At this time, rotate the hinge handle 20 downward, so that the first connecting seat 24 and the second connecting seat 26 move towards one end of the hinge seat 18, and so that the second connecting seat 26 drives the positioning column 27 to be inserted into the inner wall of the support tube 28 and the hinge seat 18 respectively, locking the fixed column 15 and the support tube 28, thereby completing the purpose of installing the mounting bracket 4 and the intermediate frequency furnace 5 with the drive frame 3.

[0036] By setting the second guide sleeve 23, the movement of the drive column 22 can be guided, so that the drive column 22 moves linearly. By setting the second slide block 30 and the second slide rail 31, the second connecting seat 26 and the first connecting seat 24 can move linearly stably, thereby improving the accuracy of the insertion between the positioning column 27 and the positioning hole 29.
