Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, specifically to a erosion-resistant ultra-low carbon magnesia-carbon brick pressing and molding equipment. Background Technology

[0002] Magnesia-carbon bricks are non-burning carbon composite refractory materials made from high-melting-point alkaline oxide magnesium oxide and high-melting-point carbon materials that are difficult to be wetted by slag, with the addition of various non-oxide additives and bonded with carbonaceous binders. Magnesia-carbon bricks are mainly used in the lining of converters, AC electric arc furnaces, DC electric arc furnaces, and slag lines of ladles.

[0003] In the prior art, Chinese patent CN207859082U proposes an automatic forming equipment for erosion-resistant magnesia-carbon bricks for stainless steel ladles. During the pressing process, the moving parts are connected to a transmission component and a smoothing component, and a buffer component is used to achieve stable air discharge from the raw material and automatic leveling of the raw material. This solves the technical problems of poor erosion resistance and low production efficiency of magnesia-carbon bricks in the prior art. However, in practical applications, there is still a problem: before pressing erosion-resistant ultra-low carbon magnesia-carbon bricks, powder needs to be placed in a forming mold. During the process of feeding the powder into the mold, air enters the mold. If the air in the mold is not treated, and there is a large amount of air in the mold, directly pressing the powder in the mold may cause the powder in the mold to spray out of the mold during the pressing process, affecting the pressing effect, or the pressed magnesia-carbon bricks may contain air, thus affecting the pass rate of the formed magnesia-carbon bricks. Therefore, we disclose an erosion-resistant ultra-low carbon magnesia-carbon brick pressing and forming equipment. Utility Model Content

[0004] The purpose of this invention is to provide an erosion-resistant ultra-low carbon magnesia-carbon brick pressing and molding equipment to solve the problem mentioned in the background art that excessive air in the mold affects the qualified rate of the molded magnesia-carbon bricks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure molding device for erosion-resistant ultra-low carbon magnesia-carbon bricks, comprising a base, a first support box fixedly connected to the bottom end of the base, a first vibration groove formed at the upper end of the base, a first limiting frame slidably connected to both ends of the first vibration groove, a second vibration groove formed at the lower end of the base, a limiting block fixedly connected to the bottom end of the first limiting frame, the limiting block slidably connected within the second vibration groove, a molding die movably sleeved between two first limiting frames, and a plurality of telescopic rods fixedly connected to one side of one of the first limiting frames. One side is fixedly connected to the base, and another first limiting frame is fixedly connected to one end of a first connecting rod. One end of the first connecting rod is rotatably connected to a second connecting rod, and one end of the second connecting rod is rotatably connected to a rotating disk. A motor is fixedly connected to the middle of the rotating disk, and the motor is fixedly connected to the base. Two rotating slots are opened on one side of the base, and the first connecting rod, the second connecting rod, and the rotating disk are all disposed in the rotating slots. A second hydraulic cylinder is fixedly connected to one side of the base, and a pressing mold is fixedly connected to the output end of the second hydraulic cylinder. The pressing mold is adapted to the forming mold.

[0006] Preferably, the second vibration groove and the limiting block are both T-shaped, a baffle is fixedly connected to the top of the base, the lower end of the baffle covers the top of the molding mold and the first vibration groove, and the top surface of the molding mold and the first limiting frame is on the same plane as the top surface of the base.

[0007] Preferably, the first limiting frame is an L-shaped plate, and two connecting plates are fixedly connected between the two first limiting frames. The two connecting plates are located at both ends of the first limiting frame. First limiting rods are fixedly connected to both sides of the forming mold, and a connecting groove opened on one side of the first limiting frame is adapted to the first limiting rod.

[0008] Preferably, a push plate is movably sleeved at the bottom end of the forming mold, and a first hydraulic cylinder is attached to the bottom end of the push plate. A rectangular hole is opened at the bottom end of the forming mold, and the length and width of the hole are both smaller than the length and width of the push plate. The bottom end of the first hydraulic cylinder slides through the base and is fixedly connected to the first support box. The first hydraulic cylinder is not attached to the connecting plate.

[0009] Preferably, the telescopic sleeve includes a telescopic rod and a spring, the telescopic rod is sleeved inside the spring, and both ends of the telescopic rod and the spring are respectively fixedly connected to the first limiting frame and the base.

[0010] Preferably, a second support box is movably sleeved on one side of the base, a movable groove is provided at one end of the second support box, a second limiting rod is slidably connected in the movable groove, one end of the second limiting rod is fixedly connected to the molding mold, a limiting plate is rotatably connected to the other end of the second support box, and a second limiting frame is fixedly connected to the outer wall of the base, and the limiting plate is movably engaged with the second limiting frame.

Furthermore, the movement of the first limiting frame will drive the molding die to move, thus limiting the movement range of the molding die. The position of the first limiting rod is fixed by the base, so that after the motor is started, it drives the rotating disk to rotate, so that the first limiting frame is driven to reciprocate in the first vibration groove through the second connecting rod and the first connecting rod, thereby causing the molding die to shake, shaking the gas in the powder put into the molding die out of the molding die, thereby making the powder in the molding die easier to press and form, and improving the molding qualification rate of magnesia-carbon bricks.

[0013] After the magnesia-carbon brick is formed, the first hydraulic cylinder is activated to push the push plate to remove the magnesia-carbon brick from the forming mold, making it easy to remove and facilitating the operation of the workers. When the forming mold shakes, it will cause the second limit rod to shake in the moving groove. When the workers need to replace the forming mold, they can pull the second support box and use the second limit rod to drive the forming mold to slide out of the first limit frame and the base, making it easy to replace the forming mold.

[0022] Example 1

[0023] Please see Figure 1-4This utility model provides an embodiment of an erosion-resistant ultra-low carbon magnesia-carbon brick pressing and molding equipment, comprising a base 1, a first support box 2 fixedly connected to the bottom end of the base 1, a first vibration groove 3 opened at the upper end of the base 1, a first limiting frame 4 slidably connected to both ends of the first vibration groove 3, a second vibration groove 18 opened at the lower end of the base 1, a limiting block 19 fixedly connected to the bottom end of the first limiting frame 4, the limiting block 19 slidably connected within the second vibration groove 18, a molding mold 6 movably sleeved between the two first limiting frames 4, a plurality of telescopic sleeve rods 5 fixedly connected to one side of one first limiting frame 4, one side of the telescopic sleeve rods 5 fixedly connected to the base 1, and a first connecting rod 8 fixedly connected to one end of the other first limiting frame 4, one end of the first connecting rod 8 rotating. A second connecting rod 9 is connected, with one end of the second connecting rod 9 rotatably connected to a rotating disk 10. A motor 11 is fixedly connected to the middle of the rotating disk 10, and the motor 11 is fixedly connected to the base 1. Two rotating slots 7 are opened on one side of the base 1, and the first connecting rod 8, the second connecting rod 9, and the rotating disk 10 are all set in the rotating slots 7. A second hydraulic cylinder 24 is fixedly connected to one side of the base 1, and a pressing mold is fixedly connected to the output end of the second hydraulic cylinder 24. The pressing mold is adapted to the forming mold 6. The second vibration groove 18 and the limiting block 19 are both T-shaped. A baffle 20 is fixedly connected to the top of the base 1, and the lower end of the baffle 20 covers the top of the forming mold 6 and the first vibration groove 3. The top surfaces of the forming mold 6 and the first limiting frame 4 are on the same plane as the top surface of the base 1. The first limiting frame 4 is an L-shaped plate. Two connecting plates 23 are fixedly connected between the two first limiting frames 4. The two connecting plates 23 are located at both ends of the first limiting frame 4. The two sides of the forming mold 6 are fixedly connected to the first limiting rods 12. The connecting groove opened on one side of the first limiting frame 4 is adapted to the first limiting rod 12. In use, the first support box 2 is fixedly connected to the bottom end of the base 1, so that the first support box 2 fixes the position of the base 1. The upper end of the base 1 is provided with a first vibration groove 3. The two ends of the first vibration groove 3 are slidably connected to the first limiting frame 4, so that the first vibration groove 3 restricts the sliding range of the first limiting frame 4. The lower end of the base 1 is provided with a second vibration groove 18. The bottom end of the first limiting frame 4 is fixedly connected to a limiting block 19. The first limiting block 19 is slidably connected within the second vibration groove 18. A forming mold 6 is movably sleeved between the two first limiting frames 4, thus restricting the sliding range of the limiting block 19 via the second vibration groove 18, thereby restricting the sliding range of the first limiting frame 4. This ensures that the first limiting frame 4 can only perform translational sliding. Furthermore, the movement of the first limiting frame 4 causes the forming mold 6 to move, further restricting the movement range of the forming mold 6. Several telescopic sleeve rods 5 are fixedly connected to one side of one first limiting frame 4, and one side of each telescopic sleeve rod 5 is fixedly connected to the base 1. This allows the base 1 to restrict the movement of one first limiting frame 4 via the telescopic sleeve rods 5. A first connecting rod 8 is fixedly connected to one end of the other first limiting frame 4, and a second connecting rod 9 is rotatably connected to one end of the first connecting rod 8.One end of the second connecting rod 9 is rotatably connected to a rotating disk 10. A motor 11 is fixedly connected to the middle of the rotating disk 10. The motor 11 is fixedly connected to the base 1, so that the base 1 fixes the position of the first limiting rod 12. After the motor 11 starts, it drives the rotating disk 10 to rotate, which in turn drives the first limiting frame 4 to reciprocate within the first vibration groove 3 via the second connecting rod 9 and the first connecting rod 8. This causes the molding mold 6 to shake, dislodging the gas in the powder inside the molding mold 6. This makes it easier for the powder inside the molding mold 6 to be pressed and formed, improving the molding qualification rate of magnesia-carbon bricks. A second hydraulic cylinder 24 is fixedly connected to one side of the base 1. The output end of the second hydraulic cylinder 24 is fixedly connected to a pressing mold. The pressing mold is adapted to the molding mold 6, so that the second hydraulic cylinder 24 drives the pressing mold to press down the powder inside the molding mold 6 to form magnesia-carbon bricks. Since both the second vibration groove 18 and the limiting block 19 are T-shaped, the limiting block 19 can only move within the second vibration groove 18. The movement direction of the first limiting frame 4 is restricted by a baffle 20 fixedly connected to the top of the base 1. The lower end of the baffle 20 covers the top of the molding mold 6 and the first vibration groove 3. The top surfaces of the molding mold 6 and the first limiting frame 4 are on the same plane as the top surface of the base 1, allowing the baffle 20 to cover the top of the first vibration groove 3 and preventing powder from falling into the base 1 through the first vibration groove 3. The first limiting frame 4 is an L-shaped plate, providing a stable support for the molding mold 6. Two connecting plates 23 are fixedly connected between the two first limiting frames 4, located at both ends of the first limiting frame 4, fixing their relative positions. First limiting rods 12 are fixedly connected to both sides of the molding mold 6. The connecting groove on one side of the first limiting frame 4 matches the first limiting rod 12, restricting the movement direction of the molding mold 6 and allowing the molding mold 6 to move horizontally together with the first limiting frame 4.

[0024] As a preferred embodiment of this example, Figures 2-4As shown, a push plate 22 is movably sleeved at the bottom of the molding die 6. A first hydraulic cylinder 21 is attached to the bottom of the push plate 22. A rectangular hole is opened at the bottom of the molding die 6. The length and width of the hole are both smaller than the length and width of the push plate 22. The bottom of the first hydraulic cylinder 21 slides through the base 1 and is fixedly connected to the first support box 2. The first hydraulic cylinder 21 is not attached to the connecting plate 23. The telescopic sleeve 5 includes a telescopic rod and a spring. The telescopic rod is sleeved inside the spring. Both ends of the telescopic rod and the spring are fixedly connected to the first limiting frame 4 and the base 1, respectively. A second support box 13 is movably sleeved on one side of the base 1. A moving groove 14 is opened at one end of the second support box 13. A second limiting rod 15 is slidably connected in the moving groove 14. One end of the base 1 is fixedly connected to the molding mold 6, and the other end of the second support box 13 is rotatably connected to the limit plate 16. The outer wall of the base 1 is fixedly connected to the second limit frame 17. The limit plate 16 and the second limit frame 17 are movably engaged. One end of the middle of the limit plate 16 is provided with a handle groove. The second limit rod 15 is a T-shaped rod. One side of the base 1 is provided with a placement groove, which is adapted to the second support box 13 and the molding mold 6. A push plate 22 is movably sleeved at the bottom of the molding mold 6. The bottom end of the push plate 22 is attached to the first hydraulic cylinder 21. After the magnesia-carbon brick is formed, the first hydraulic cylinder 21 is activated to push the push plate 22 to remove the magnesia-carbon brick formed in the molding mold 6. This makes it easy to remove the magnesia-carbon brick and facilitates the operation of the workers. The bottom of the mold 6 has a rectangular hole, the length and width of which are smaller than the length and width of the push plate 22. This restricts the movement distance of the push plate 22. The first hydraulic cylinder 21 does not contact the connecting plate 23, preventing interference between them. A telescopic sleeve 5, including a telescopic rod and a spring, is used. The telescopic rod is fitted inside the spring, and both ends of the telescopic rod and spring are fixedly connected to the first limiting frame 4 and the base 1, respectively. This allows the base 1 to restrict the movement of the first limiting frame 4 via the telescopic sleeve 5, facilitating its reciprocating movement. A second support box 13 is movably fitted onto one side of the base 1. One end of the second support box 13 has a moving groove 14, within which a sliding connection is made. The second limiting rod 15 has one end fixedly connected to the molding mold 6, so that when the molding mold 6 shakes, it will cause the second limiting rod 15 to shake within the moving groove 14. When the operator needs to replace the molding mold 6, the second support box 13 can be pulled, and the molding mold 6 can be slid through the second limiting rod 15, so that the molding mold 6 slides out of the first limiting frame 4 and the base 1, making it easy to replace the molding mold 6. The other end of the second support box 13 is rotatably connected to the limiting plate 16. The outer wall of the base 1 is fixedly connected to the second limiting frame 17, and the limiting plate 16 and the second limiting frame 17 are movably engaged, so that the base 1 restricts the movement of the limiting plate 16 through the second limiting frame 17, thereby restricting the movement of the second support box 13 and the molding mold 6.Furthermore, the rotation direction of the limiting plate 16 and the movement direction of the forming mold 6 are intersected, ensuring the stable position of the forming mold 6 within the first limiting frame 4. A handle groove is provided at one end of the middle of the limiting plate 16, and the second limiting rod 15 is a T-shaped rod, facilitating the use of the limiting plate 16 and ensuring a stable connection between the second limiting rod 15 and the second support box 13, allowing the second support box 13 to move the forming mold 6.

[0025] Work steps

[0026] In this embodiment, the following steps are taken: First, the motor 11 starts and drives the rotating disk 10 to rotate, which in turn drives the first limiting frame 4 to reciprocate within the first vibration groove 3 via the second connecting rod 9 and the first connecting rod 8. This causes the molding mold 6 to shake, dislodging the gas in the powder inside the molding mold 6 and making it easier to press and form the powder, thus improving the molding qualification rate of magnesia-carbon bricks. After the magnesia-carbon bricks are formed, the first hydraulic cylinder 21 is activated to push the push plate 22 to remove the magnesia-carbon bricks from the molding mold 6, making it easy to remove and facilitating the work of the staff. When the staff needs to replace the molding mold 6, the second support box 13 can be pulled to slide the molding mold 6 via the second limiting rod 15, allowing the molding mold 6 to slide out of the first limiting frame 4 and the base 1, making it easy to replace the molding mold 6.
