Description

[0001] The invention relates to the technical field of stopper rod processing, and in particular to a device for processing and forming an integral stopper rod. Background Art

[0002] With the continuous development of society and the continuous advancement of science and technology, stopper rods play a vital role in the continuous casting process. It is a functional refractory material, mainly used to control and regulate the flow of molten steel. The performance of the stopper rod directly affects the smooth progress of the continuous casting process. Therefore, it is of great significance to develop stopper rods with excellent thermal shock resistance, erosion resistance, corrosion resistance, long service life and low cost.

[0003] When the existing integral stopper rod processing and forming equipment is in use, workers need to pour the stopper rod raw material into the smelting furnace through the discharge port. Due to the high temperature of the smelting furnace, workers may be burned if they are close to the smelting furnace, which poses certain safety hazards. At the same time, when the stopper rod raw material is discharged, due to the stickiness of the stopper rod raw material, it may adhere to the side wall of the discharge port and block the discharge port, which will affect the discharge efficiency and reduce the production efficiency of the stopper rod. Summary of the invention

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art: when the existing integral stopper rod processing and forming equipment is in use, workers need to pour the stopper rod raw material into the smelting furnace through the discharge port. Since the smelting furnace has a high temperature, workers may be burned if they are close to the smelting furnace, which poses certain safety hazards. At the same time, when the stopper rod raw material is discharged, due to the stickiness of the stopper rod raw material, it may adhere to the side wall of the discharge port and block the discharge port, which will affect the discharge efficiency and reduce the production efficiency of the stopper rod. Therefore, an integral stopper rod processing and forming equipment is proposed.

[0006] Preferably, a trapezoidal plate is fixedly connected inside the material transport hopper, the trapezoidal plate is provided with an extrusion groove, a discharge plate is slidably connected inside the extrusion groove, a straight spring is fixedly connected between the discharge plate and the inner wall of the extrusion groove, an extrusion through hole is provided at one end of the material transport hopper, and the discharge plate is slidably connected inside the extrusion through hole.

[0007] Preferably, a feed through hole is opened on the upper surface of the straight plate, a feed cavity is slidably connected in the feed through hole, and two fixed blocks are fixedly connected to the upper surface of the straight plate.

[0008] Preferably, a connecting plate is slidably connected inside the fixed block, a return spring is fixedly connected between the connecting plate and the upper surface of the straight plate, an extrusion block is fixedly connected to the upper surface of the connecting plate, and the feeding cavity is fixedly connected between the two connecting plates.

[0009] Preferably, a pressure plate is fixedly connected to the upper surface of the straight plate, and two extrusion rods are fixedly connected to the outer surface of the pressure plate.

[0010] Preferably, a rack plate is fixedly connected to the lower surface of the material transport hopper, an exhaust chamber is fixedly connected to the upper surface of the placement plate, and a rotating rod is rotatably connected to the exhaust chamber.

[0011] Preferably, one end of the rotating rod passing through the straight plate is fixedly connected with a spur gear, and the spur gear is meshed with the rack plate.

[0012] Preferably, a piston plate is slidably connected in the exhaust chamber, the piston plate is threadedly connected to the rotating rod, a smelting furnace is fixedly connected to the upper surface of the placement plate, and an insulation chamber is fixedly connected to the outer surface of the smelting furnace.

[0013] Preferably, a connecting pipe is fixedly connected between the insulation chamber and the exhaust chamber, and a plurality of stopper rod molds are fixedly installed in the smelting furnace.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The rotation of the rotating shaft drives the moving block to move on the guide rail, so that the material transport hopper gradually approaches the unloading chamber of the smelting furnace to avoid high temperature burns caused by the workers needing to approach the smelting furnace for unloading. When the material transport hopper contacts the extrusion rod, the extrusion rod squeezes the unloading plate to move into the trapezoidal plate until the unloading port is completely exposed. At this time, the stopper rod material in the material transport hopper passes through the unloading chamber into the stopper rod mold of the smelting furnace to complete the automatic unloading work.

[0015] 2. When the material transport hopper contacts the extrusion rod, the arc block on the outer surface of the material transport hopper squeezes the impact rod, and the impact rod is pressed to move into the knocking chamber. At this time, the square plate squeezes the adjusting spring, and the adjusting spring is compressed. When the arc block no longer squeezes the impact rod, the impact rod is affected by the adjusting spring and hits the outer surface of the material transport hopper. The material transport hopper vibrates due to the impact, thereby preventing the stopper rod material from sticking to the inner wall of the material transport hopper. At the same time, it can also assist the stopper rod material in unloading and increase the unloading speed.

[0016] 3. By rotating the threaded rod at one end of the knocking chamber, the adjusting plate can move horizontally in the knocking chamber. The horizontal movement of the adjusting plate can control the original compression degree of the adjusting spring, thereby controlling the thrust of the adjusting spring on the impact rod, so that the knocking chamber can adjust the impact force according to the adhesion of different stopper rod materials, thereby improving the applicability of the knocking chamber.

[0017] 4. The extrusion block is extruded by the movement of the material transport hopper. The extrusion block is pressed to drive the connecting plate to move. The movement of the connecting plate drives the material discharge cavity to move, so that the material discharge cavity and the material transport hopper are tightly fitted. When the knocking chamber is working, the material transport hopper vibrates. This vibration will cause a tiny gap between the material discharge cavity and the material transport hopper. This gap may cause the stopper rod material to splash onto the straight plate, resulting in a waste of raw materials. At this time, the reset spring will make the material discharge cavity and the material transport hopper always fit tightly during the vibration process to avoid the waste of stopper rod material.

[0018] 5. The movement of the material transport hopper drives the rack plate to move. When the rack plate moves to the spur gear, the rack plate drives the spur gear to rotate. The rotation of the spur gear drives the rotating rod to rotate. The rotation of the rotating rod drives the piston plate to move upward, so that the gas in the insulation chamber is extracted through the connecting pipe to ensure that the insulation chamber is close to a vacuum state, reduce the heat dissipation of the smelting furnace, make the smelting furnace have a certain insulation effect, and reduce energy loss.

The rotating rod 28 passes through one end of the straight plate 1 and is fixedly connected to a spur gear 27. The spur gear 27 is meshed with the rack plate 26. A piston plate 29 is slidably connected in the vacuum chamber 30, and a sealing ring is sleeved around the piston plate 29. To ensure that the piston plate 29 does not leak when moving, the piston plate 29 is threadedly connected to the rotating rod 28. A smelting furnace 33 is fixedly connected to the upper surface of the placement plate 3. The smelting furnace 33 is a prior art, and its working principle is the same as that of the electromagnetic smelting furnace in the prior art. High temperature is generated by powering on to heat the internal container. A holding chamber 31 is fixedly connected to the outer surface of the smelting furnace 33. The holding chamber 31 is annular and hollow inside. A connecting pipe 32 is fixedly connected between the holding chamber 31 and the exhaust chamber 30. A one-way valve is provided in the connecting pipe 32 to ensure that gas does not enter the holding chamber 31. A plurality of stopper rod molds 34 are fixedly installed in the smelting furnace 33.

[0024] In the present invention, the rotating shaft 7 is driven to rotate by an external servo motor connected to the rotating shaft 7, and the rotating shaft 7 drives the moving block 6 to move on the guide rail 4, so that the material transport hopper 5 gradually approaches the material discharge cavity 21 of the smelting furnace 33, avoiding high temperature burns caused by the workers needing to approach the smelting furnace 33 for material discharge. When the material transport hopper 5 contacts the extrusion rod 20, the extrusion rod 20 squeezes the material discharge plate 16 to move into the trapezoidal plate 17 until the material discharge port is completely exposed. At this time, the stopper rod material in the material transport hopper 5 passes through the material discharge cavity 21 and enters the stopper rod mold 34 of the smelting furnace 33, completing the automatic discharge. When the material transport hopper 5 contacts the extrusion rod 20, the arc block 8 on the outer surface of the material transport hopper 5 squeezes the impact rod 11, and the impact rod 11 is pressed to move into the knocking chamber 9. At this time, the square plate 10 squeezes the adjusting spring 12, and the adjusting spring 12 is compressed.

The material transport hopper 5 vibrates due to the impact, thereby preventing the stopper rod raw material from sticking to the inner wall of the material transport hopper 5. At the same time, it can also assist the stopper rod raw material in unloading and increase the unloading speed.

[0025] By rotating the threaded rod 14 at one end of the knocking chamber 9, the adjusting plate 13 is moved horizontally in the knocking chamber 9. The horizontal movement of the adjusting plate 13 can control the original compression degree of the adjusting spring 12, thereby controlling the thrust of the adjusting spring 12 on the impact rod 11, so that the knocking chamber 9 can adjust the impact force according to the adhesion of different stopper rod materials, thereby improving the applicability of the knocking chamber 9. The extrusion block 24 is squeezed by the movement of the material transport hopper 5. The extrusion block 24 is pressed to drive the connecting plate 25 to move. The movement of the connecting plate 25 drives the discharge cavity 21 to move, so that the discharge cavity 21 is tightly fitted with the material transport hopper 5. When the knocking chamber 9 is working, the material transport hopper 5 vibrates. This vibration will cause a tiny gap between the discharge cavity 21 and the material transport hopper 5. This gap may cause the stopper rod material to splash onto The straight plate 1 is on the straight plate 1, resulting in a waste of raw materials. At this time, the return spring 23 will make the feeding chamber 21 and the material transport hopper 5 closely fit at all times during the vibration process to avoid the waste of the stopper rod raw materials. The movement of the material transport hopper 5 drives the rack plate 26 to move. When the rack plate 26 moves to the spur gear 27, the rack plate 26 drives the spur gear 27 to rotate. The rotation of the spur gear 27 drives the rotating rod 28 to rotate. The rotation of the rotating rod 28 drives the piston plate 29 to move upward, so that the gas in the insulation chamber 31 is extracted through the connecting pipe 32. There will be some gas in the insulation chamber 31 each time it is used. Extracting this part of the gas can improve the insulation effect of the insulation chamber 31, ensure that the insulation chamber 31 is close to a vacuum state, reduce the heat dissipation of the smelting furnace 33, so that the smelting furnace 33 has a certain insulation effect and reduces energy loss.
