Description
Technical Field
[0001] The invention relates to the technical field of casting equipment, and in particular to a casting equipment. Background Art
[0002] Hot metal casting refers to pouring hot molten iron into a pre-prepared mold, and then taking out the mold after it cools and solidifies to obtain a casting of the desired shape. According to the different pouring processes and the purpose of the casting, hot metal casting can be divided into ordinary casting, special casting and continuous casting. Among them, ordinary casting includes sand casting, metal mold casting, etc.; special casting includes investment casting, pressure casting, etc.; continuous casting is mainly used to produce long strip castings, such as cast steel billets, cast iron pipes, etc.
[0003] At present, molten iron casting is usually carried out manually. First, iron ore or other iron-containing raw materials need to be melted into liquid iron at high temperature, and the liquid iron is poured into an iron ladle (container). The iron ladle is then manually transferred to the casting site, and the container is used to manually cast the molten iron in the iron ladle into the mold. This casting process requires manual operation and has high labor intensity, which is especially not suitable for mass casting. In addition, due to the influence of human factors, the precision of the casting is not high. Summary of the invention
[0004] The present invention is intended to provide a casting device, so as to provide a device for replacing manual casting and improving the precision of castings.
[0005] In order to solve the above problems, the present invention provides the following technical solutions:
[0006] A casting equipment comprises a base, the base is coaxially connected to a rotating arm, the base is fixed with a first motor for driving the rotating arm of the bracket to rotate, the rotating arm is installed with a lifting frame, the lifting frame is rotatably connected to a rotating seat, the axis of the rotating seat is perpendicular to the axis of the lifting frame, the rotating seat is coaxially connected to an operating rod, the operating rod is coaxially fixedly sleeved with a mounting bracket, and the mounting bracket is installed with an iron bag.
[0007] Working principle and beneficial effects of the present invention:
[0008] In this solution, the first motor drives the rotating arm to rotate, and the rotating arm drives the lifting frame, the lifting frame and the iron ladle to move to the furnace, and the molten iron is poured into the iron ladle. Then, the first motor drives the rotating arm to rotate, and the rotating arm drives the lifting frame, the mounting bracket and the iron ladle to move to the mold. Since the rotating seat and the lifting frame are rotatably connected, the rotating seat is coaxially rotatably connected with an operating rod, and the axis of the operating rod is perpendicular to the axis of the rotating seat, the rotating seat is driven by the swinging operating rod to rotate the mounting bracket and the iron ladle to the top of the casting port of the mold, and then the operating rod is rotated to tilt the mounting bracket and the iron ladle, and the molten iron in the iron ladle is injected into the mold.
[0009] This solution replaces the manual operation method of the prior art with a mechanical method, and the position of the iron ladle can be changed at will, so it has stronger applicability and higher precision of the casting.
[0010] Optimally, the lifting frame is hinged to the rotating arm, and a lifting cylinder is hinged between the lifting frame and the rotating arm. The lifting frame is driven by the lifting cylinder to lift and lower the iron ladle, which is beneficial for pouring molten iron into the iron ladle and for moving the iron ladle to the top of the mold.
[0011] Optimally, the lifting frame is fixedly provided with a second motor for driving the rotating seat, the rotating seat is fixedly provided with a third motor for driving the operating rod to rotate, and the first motor, the second motor and the third motor are all servo motors. The servo motor has a self-locking function, and under the self-locking effect of the first motor, the second motor and the third motor, the iron ladle, the rotating seat and the mounting bracket will not shake during the rotation of the lifting frame, thereby preventing the molten iron from spilling, and also ensuring the stability of the casting process, and improving the casting accuracy.
[0012] Optimally, the ladle is provided with a casting pipe, the casting pipe is hinged with multiple sliding openings staggered along its axis, each sliding opening is slidably connected to a refrigeration fin, a spring is fixedly provided between the refrigeration fin and the casting pipe, the casting pipe is coaxially rotatably connected to a sleeve, the casting pipe is fixedly provided with a fourth motor for driving the sleeve to rotate, the inner wall of the sleeve is fixedly provided with an arc block abutting against each refrigeration fin, and the thickness of the arc block gradually increases in the counterclockwise direction.
[0013] Since multiple cooling plates are staggered in the casting tube, the cooling plates play a role in blocking the flow of molten iron, and the flow rate of molten iron is reduced by the cooling plates, and the sleeve is driven to rotate by the fourth motor, and the sleeve drives multiple arc blocks to rotate. At this time, the spring is in a compressed state, and the extrusion amplitude of the multiple arc blocks on the cooling plates is reduced after the rotation, and the compressed spring is restored, so that the cooling plates extend out of the casting tube through the sliding port, and the part of the cooling plates located in the casting tube is reduced, and the blocking effect of the cooling plates on the molten iron is reduced, and the flow rate of the molten iron can be adjusted; and the cooling plates are energized to cool the molten iron, and reducing the flow rate of the molten iron can increase the residence time of the molten iron in the casting tube. The cooling plates can cool the molten iron and reduce the temperature of the molten iron. The purpose of doing so is that the thermal stress generated by the pre-cooled molten iron during the casting process is small, and the thermal shock to the mold and equipment is also small, thereby extending the service life of the mold and equipment. In some cases, such as in the continuous casting process, the pre-cooled molten iron can reduce the scouring and adhesion of the pouring nozzle, prevent the occurrence of nozzle blockage, and realize long-term continuous casting under low superheat. During the cooling process, some volatile substances in the molten iron will precipitate and solidify on the surface of the molten iron, reducing the generation of smoke and dust during the pouring process, which is beneficial to environmental protection and workers' health.
[0014] Furthermore, the portion of the refrigeration fin located in the casting tube is reduced, so the refrigeration area of each refrigeration fin located in the casting tube can be reduced, thereby controlling the refrigeration speed of the molten iron and controlling the temperature of the molten iron after refrigeration.
[0015] Optimally, the refrigeration plate is wrapped with a sealing gasket to enhance the sealing effect.
[0016] Optimally, the iron bag and the mounting bracket are fixed by bolts. This optimization solution can realize the disassembly of the iron bag.
[0017] Optimally, the amplitude variation of the arc-shaped block on the side away from the iron ladle is smaller than the amplitude variation of the arc-shaped block on the side close to the iron ladle. When the sleeve rotates, the arc-shaped block on the side close to the iron ladle has a large extrusion amplitude on the cooling fin, while the arc-shaped block on the side away from the iron ladle has a small extrusion amplitude on the cooling fin, thereby satisfying the function of reducing the cooling speed of the molten iron and slowing down the flow speed of the molten iron.
[0018] Optimally, the refrigeration plate is a high temperature resistant refrigeration plate. The high temperature resistant refrigeration plate has the function of resisting the high temperature of molten iron. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The figure marks in the drawings of the specification include: base 1, first motor 2, rotating arm 3, cylinder 4, operating rod 5, second motor 6, lifting frame 7, rotating seat 8, casting pipe 9, iron bag 10, mounting bracket 11, arc block 12, sleeve 13, spring 14, cooling plate 15, fourth motor 16.
[0025] In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.
[0026] Embodiment 1: A casting device, such as Figure 1 As shown, it includes a base 1, the base 1 is coaxially rotatably connected with a rotating arm 3, the base 1 is fixedly provided with a first motor 2 for driving the rotating arm 3 of the bracket to rotate, the rotating arm 3 is hinged with a lifting frame 7, and a cylinder 4 is hinged between the lifting frame 7 and the rotating arm 3. The lifting frame 7 is rotatably connected with a rotating seat 8, the axis of the rotating seat 8 is perpendicular to the axis of the lifting frame 7, the rotating seat 8 is coaxially rotatably connected with an operating rod 5, the operating rod 5 is coaxially fixedly sleeved with a mounting bracket 11, the mounting bracket 11 is installed with an iron bag 10, and the iron bag 10 includes a casting pipe 9. The lifting frame 7 is fixedly provided with a second motor 6 for driving the rotating seat 8, and the rotating seat 8 is fixedly provided with a third motor for driving the operating rod 5 to rotate, and the first motor 2, the second motor 6 and the third motor are all servo motors.
[0027] In this solution, the first motor 2 drives the rotating arm 3 to rotate, and the rotating arm 3 drives the lifting frame 7, the lifting frame 7 and the iron ladle 10 to move to the furnace, and the molten iron is poured into the iron ladle 10, and then the first motor 2 drives the rotating arm 3 to rotate, and the rotating arm 3 drives the lifting frame 7, the mounting bracket 11 and the iron ladle 10 to move to the mold. Since the rotating seat 8 and the lifting frame 7 are rotatably connected, the rotating seat 8 is driven to rotate by the second motor 6,
[0028] The rotating seat 8 is driven to rotate the mounting bracket 11 and the iron ladle 10 to the top of the casting port of the mold, and then the operating rod 5 is driven by the third motor to rotate to tilt the mounting bracket 11 and the iron ladle 10, and the molten iron in the iron ladle 10 is injected into the mold through the casting pipe 9.
[0029] The servo motor has a self-locking function. Under the self-locking action of the first motor 2, the second motor 6 and the third motor, the iron ladle 10, the rotating seat 8 and the mounting bracket 11 are ensured not to shake during the rotation of the lifting frame 7, thereby preventing the molten iron from spilling, while also ensuring the stability of the casting process and improving the casting accuracy.
[0030] This solution replaces the manual operation method of the prior art with a mechanical method, and the position of the iron ladle 10 can be changed at will, so it has stronger applicability and higher precision of the casting.
[0031] Example 2: Figure 2 and Figure 4 As shown, the casting tube 9 is staggered and hinged with 8 sliding openings along its axis, each sliding opening is slidably connected with a refrigeration fin 15, the refrigeration fin 15 is wrapped with a sealing gasket for sealing and high temperature resistance, a spring 14 is fixed between the refrigeration fin 15 and the casting tube 9, the casting tube 9 is coaxially rotatably connected with a sleeve 13, the casting tube 9 is fixedly provided with a fourth motor 16 for driving the sleeve 13 to rotate, the inner wall of the sleeve 13 is fixedly provided with an arc block 12 abutting against each refrigeration fin 15, and the thickness of the arc block 12 gradually increases in the counterclockwise direction.
[0032] Since the eight cooling fins 15 are staggeredly arranged in the casting tube 9, the cooling fins 15 play a role in blocking the flow of molten iron, and the flow speed of the molten iron is reduced by the cooling fins 15. Figure 3 As shown, the sleeve 13 is driven to rotate by the fourth motor 16, and the sleeve 13 drives the 8 arc blocks 12 to rotate. At this time, the spring 14 is in a compressed state. After the 8 arc blocks 12 rotate, the extrusion amplitude of the refrigeration plate 15 is reduced, and the compressed spring 14 is restored, so that the refrigeration plate 15 extends out of the casting tube 9 through the sliding port, and the part of the refrigeration plate 15 located in the casting tube 9 is reduced, and the blocking effect of the refrigeration plate 15 on the molten iron is reduced, so the flow rate of the molten iron can be adjusted; and the refrigeration plate 15 is energized to cool the molten iron, and reducing the flow rate of the molten iron can increase the residence time of the molten iron in the casting tube 9. The refrigeration plate 15 can cool the molten iron and reduce the temperature of the molten iron. The purpose of doing so is that the thermal stress generated by the pre-cooled molten iron during the casting process is small, and the thermal shock to the mold and equipment is also small, thereby extending the service life of the mold and equipment. In some cases, such as in the continuous casting process, the pre-cooled molten iron can reduce the scouring and adhesion of the pouring nozzle, prevent the occurrence of nozzle blockage, and realize long-term continuous casting at low superheat. During the cooling process, some volatile substances in the molten iron will precipitate and solidify on the surface of the molten iron, reducing the generation of smoke and dust during the pouring process, which is beneficial to environmental protection and workers' health.
[0033] Furthermore, the portion of the cooling fins 15 located in the casting tube 9 is reduced, so that the cooling area of each cooling fin 15 located in the casting tube 9 can be reduced, thereby controlling the cooling speed of the molten iron and controlling the temperature of the molten iron after cooling.
