Abstract
Description
Technical Field
[0001] This utility model relates to the field of medium frequency furnace technology, and in particular to a material discharge mechanism for a medium frequency furnace. Background Technology
[0002] Medium frequency furnaces generate high-density magnetic lines of force through capacitors and induction coils. These magnetic lines of force cut through the metal material placed in the induction coil, thereby generating large eddy currents in the metal material. Eddy currents have the properties of medium frequency currents, that is, the free electrons of the metal itself flow in the resistive metal body and generate heat, thereby heating or melting the metal.
[0003] When feeding the molten metal, the angle of the furnace body is adjusted by a hydraulic mechanism on the outside of the induction furnace, so that the molten metal inside the furnace is poured into a collection container such as a crucible through the feeding port. Therefore, the entire weight of the furnace body acts on the hydraulic cylinder. In existing induction furnaces, there is no protective mechanism to prevent the furnace body from falling suddenly when the hydraulic cylinder fails. If the hydraulic cylinder fails, the furnace body will not be able to tilt at the expected angle, resulting in poor pouring of molten metal or pouring into the wrong position, and may even cause molten metal to splash out, posing a safety threat to the operators. Utility Model Content
[0004] The purpose of this invention is to provide a discharge mechanism for a medium-frequency furnace, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A discharge mechanism for a medium-frequency furnace includes a furnace frame with two fixed seats fixedly mounted on it. A fixed shaft is fixedly mounted within each fixed seat. A cover is rotatably connected between the two fixed shafts. A furnace body is fixedly mounted within the cover. Hydraulic cylinders are movably connected between the cover and the furnace frame on both sides. Limiting wheels are fixedly mounted on the outer sides of the fixed shafts. A frame is fixedly mounted on both sides of the cover near the corresponding limiting wheels. A directional sleeve is fixedly mounted on one side of the frame. A directional shaft is movably mounted within the directional sleeve. A first limiting block is movably mounted at the lower end of the directional shaft. A cylinder is fixedly mounted on the frame and connected to an external air pump via a pipeline.
[0007] As a further preferred embodiment of this utility model, a plurality of second limiting blocks are fixedly installed on the outer side of the limiting wheel. The limiting wheel is set on the outer side of the fixed shaft, and a plurality of second limiting blocks are set on the outer side of the limiting wheel, which can provide conditions for preventing the cover from falling and limiting the furnace body.
[0008] As a further preferred embodiment of this utility model, a protective cover is also fixedly installed on the upper end of the frame, and the cylinder is located inside the protective cover. The protective cover is made of heat-insulating material, which can protect the cylinder and prevent the high temperature of the molten metal from affecting the operation of the cylinder during material feeding.
[0009] As a further preferred embodiment of this utility model, two guide blocks are fixedly installed at the upper and lower ends of the adjusting sleeve, and the two guide blocks at the upper end of the adjusting sleeve and the two guide blocks at the lower end are arranged alternately.
[0010] As a further preferred embodiment of this utility model, two first guide blocks are fixedly installed on the outer side of the directional shaft, and two second guide blocks are also fixedly installed on the directional shaft located below the first guide blocks. The two first guide blocks and the two second guide blocks are staggered. A telescopic groove is provided at the lower end of the directional shaft, and a limit screw is threadedly connected to one side of the telescopic groove. The directional shaft is inserted into the directional sleeve, and the first guide blocks and the second guide blocks are respectively placed between two corresponding guide inclined blocks. The upper end of the directional shaft is rotatably connected to the lower end of the piston rod of the cylinder.
[0011] As a further preferred embodiment of this utility model, a sliding groove is provided on one side of the first limiting block, the lower end of the first limiting block is sloping, the upper end of the first limiting block is inserted into the telescopic groove, and one end of the limiting screw is inserted into the sliding groove. A compression spring is also inserted into the telescopic groove located above the first limiting block. After the adjusting shaft is inserted into the adjusting sleeve, it can cooperate with two sets of guide blocks, the first guide block, and the second guide block to realize the rotation of the adjusting shaft during the lifting and lowering process, thereby driving the first limiting block to perform the adjusting operation.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In this invention, a limiting wheel is provided on the outside of the fixed shaft, and multiple first limiting blocks are provided on the outside of the limiting wheel. This allows the first limiting blocks on both sides of the cover, which are adjusted towards the lower end of the shaft, to engage with the corresponding two first limiting blocks. This allows the cover to be rotated and limited in real time according to its rotation direction, thereby preventing the cover from falling rapidly to one side due to hydraulic cylinder failure. This also prevents molten metal from splashing out of the furnace and also prevents the rapidly falling cover from impacting the furnace frame and damaging the equipment. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] like Figures 1-4 As shown, the present invention provides a medium-frequency furnace discharge mechanism, including a furnace frame 1, two fixed seats 2 are fixedly installed on the furnace frame 1, a fixed shaft 3 is fixedly installed inside the fixed seat 2, a cover 4 is rotatably connected between the two fixed shafts 3, a furnace body 5 is fixedly installed inside the cover 4, and hydraulic cylinders 6 are movably connected between the two sides of the cover 4 and the furnace frame 1, a limit wheel 7 is fixedly installed on the outside of the fixed shaft 3, a frame 8 is fixedly installed on both sides of the cover 4 near the corresponding limit wheel 7, an adjusting sleeve 9 is fixedly installed on one side of the frame 8, an adjusting shaft 10 is movably installed inside the adjusting sleeve 9, a first limit block 11 is movably installed at the lower end of the adjusting shaft 10, and a cylinder 12 is fixedly installed on the frame 8, and the cylinder 12 is connected to an external air pump through a pipeline.
[0021] Multiple second limiting blocks 13 are fixedly installed on the outer side of the limiting wheel 7. The limiting wheel 7 is set on the outer side of the fixed shaft 3, and multiple second limiting blocks 13 are set on the outer side of the limiting wheel 7, which can provide conditions for the anti-fall limiting of the face cover 4 and the furnace body 5. A protective cover 14 is also fixedly installed on the upper end of the frame 8, and the cylinder 12 is located inside the protective cover 14. The protective cover 14 is made of heat-insulating material. The protective cover 14 can protect the cylinder 12 and prevent the high temperature of the molten metal from affecting the operation of the cylinder 12 during material feeding. Two guide inclined blocks 15 are fixedly installed on the upper and lower ends of the adjusting sleeve 9, and the two guide inclined blocks 15 on the upper end of the adjusting sleeve 9 and the two guide inclined blocks 15 on the lower end are arranged alternately. Two first guide blocks 16 are fixedly installed on the outer side of the adjusting shaft 10. Two second guide blocks 17 are also fixedly installed on the adjusting shaft 10 below the first guide blocks 16. The two first guide blocks 16 and the two second guide blocks 17 are fixedly installed on the adjusting shaft 10. The directional shaft 10 is staggered and has a telescopic groove 18 at its lower end. A limit screw 19 is threaded into one side of the telescopic groove 18. The directional shaft 10 is inserted into the directional sleeve 9. The first guide block 16 and the second guide block 17 are respectively placed between two corresponding guide inclined blocks 15. The upper end of the directional shaft 10 is rotatably connected to the lower end of the piston rod of the cylinder 12. A sliding groove 20 is provided on one side of the first limit block 11. The lower end of the first limit block 11 is sloping. The upper end of the first limit block 11 is inserted into the telescopic groove 18, and one end of the limit screw 19 is inserted into the sliding groove 20. A compression spring 21 is also inserted into the telescopic groove 18 located above the first limit block 11. After the directional shaft 10 is inserted into the directional sleeve 9, it can cooperate with the two sets of guide inclined blocks 15, the first guide block 16, and the second guide block 17 to realize the rotation of the directional shaft 10 during the lifting and lowering process, thereby driving the first limit block 11 to perform the directional operation.
[0022] It should be noted that this utility model is a discharge mechanism for a medium-frequency furnace. When the two hydraulic cylinders 6 push the cover 4 to rotate around the two fixed shafts 3, the fixed shafts 3 synchronously drive the outer limiting wheel 7 to rotate. This causes the multiple second limiting blocks 13 on the outer side of the limiting wheel 7 to sequentially push the first limiting block 11 upwards. As a result, the upper end of the first limiting block 11 reciprocates within the telescopic groove 18 in conjunction with the compression spring 21. This allows the first limiting block 11 to sequentially engage between the corresponding two second limiting blocks 13 when the limiting wheel 7 rotates clockwise, thus achieving unidirectional limiting of the cover 4. After the furnace body 5 completes the discharge, the piston rod of the cylinder 12 can lift the adjusting shaft 10, causing the adjusting shaft 10 to drive the outer first guide block 16 and second guide block 17 to move upwards synchronously, thus allowing the material to pass through the first guide block 16. The two guide blocks 17 rotate 45 degrees by limiting the guidance of the two guide ramps 15 at the lower end of the adjusting sleeve 9. This causes the adjusting shaft 10 to drive the two first guide blocks 16 to rotate to the upper end of the two guide ramps 15 above the slope. When the piston rod of the cylinder 12 pushes the adjusting shaft 10 down to reset, the two first guide blocks 16 are affected by the slope of the two guide ramps 15 at the upper end of the adjusting sleeve 9 and rotate 45 degrees. Then, the above actions are repeated in sequence. During the two rises and two falls, the adjusting shaft 10 drives the first limit block 11 to rotate 180 degrees. This causes the slope at the lower end of the first limit block 11 to be adjusted, so that the cover 4 drives the frame 8, the adjusting sleeve 9, the cylinder 12, and the adjusting shaft 10 to reset and rotate. This also ensures that the first limit block 11 does not affect the reset and rotation of the cover 4.
