Description

Technical Field

[0001] The utility model relates to a casting device, more specifically to an environmentally friendly continuous casting machine used for metal smelting. Background Art

[0002] In the metal smelting industry, the raw metal undergoes a series of processes such as heating, slag removal, reduction, and catalysis to form the required molten metal before casting. The traditional casting methods are pit casting or mold casting. Among them: the pit type has a large one-time casting volume, but it needs to be crushed secondary later, and the casting is time-consuming and labor-intensive; the stereotyped mold casting production scale is small, cannot meet production needs, and the mold production cost is high. In addition, in the casting and cooling process of some products, inert gas protection or catalytic gas is added to assist metallurgy, and sometimes certain harmful gases are generated. The labor protection requirements for operators in production are high, there are certain occupational safety hazards, and the operation is inconvenient. Utility Model Content

[0003] The utility model solves the above technical problems and proposes an environmentally friendly continuous casting machine to achieve continuous casting production with high production efficiency.

[0007] The mold is provided with a plurality of molds which are arranged on the conveying plate chain at equal intervals along the conveying direction. Each mold passes through the spraying station, the pouring station and the demoulding station in sequence along the conveying mechanism. The mold is in a bucket structure and is open at one end facing outwards in a direction perpendicular to the conveying plate chain.

[0008] The spraying mechanism is independent of the conveying mechanism, is arranged outside the conveying mechanism, and is located at the spraying station, and is used to spray the release agent to the inner wall of each mold passing through the spraying station through a spray head, and the spraying direction of the spray head is directly facing the open end of the passing mold;

[0009] The pouring mechanism is independent of the conveying mechanism and is located at the pouring station. The open end of the mold moves vertically upward to the pouring station and is located directly below the pouring head of the pouring mechanism. The pouring head of the pouring mechanism can be reciprocated between the initial position and the pouring position. When in the initial position, the pouring head is suspended above the mold with a gap between them. When it descends from the initial position to the pouring position, it faces the open end of the mold directly below, and is used to inject the metal solution into the mold.

[0010] The collecting mechanism covers the conveying mechanism and the spraying station and the pouring station on the conveying track together through the dust removal cover assembly. The dust removal cover assembly is connected to the dust removal fan through the air duct, and the dust removal fan absorbs the harmful gas in the dust removal cover through the air duct;

[0011] The demoulding mechanism is used for demoulding the ingot solidified in the mold. It is arranged on the outside of the conveying mechanism and located at the demoulding station. It is provided with a power component, a transmission component and an execution component. The power component is a demoulding sprocket of a chain transmission structure formed by a transmission chain and a driving sprocket of the conveying mechanism, and rotates synchronously with the driving sprocket.

The traction screw is horizontally arranged along the conveying direction, one end of which is fixedly connected to the slider of the linear slide, and the other end cantilevered outside the frame is sleeved with the spring. The deformation direction of the spring is arranged along the conveying direction and is tensioned between the spring pressure cover on the traction screw and the frame of the conveying mechanism. The position of the spring pressure cover on the traction screw is adjustable by an adjusting nut threadedly mounted on the traction nut. The driven sprocket axle of the conveying mechanism is supported by a bearing on the slider of the linear slide and can be displaced synchronously with the slide.

[0014] The mold is in a trapezoidal bucket structure, with the trapezoidal bottom serving as an open end.

[0015] The spraying mechanism comprises a release agent storage tank with an agitator and a release agent delivery pipe for delivering the release agent in the tank to the nozzle. The release agent storage tank is used to store the release agent, has an open top and extends toward the delivery mechanism on the side facing the mold to form a guide plate with a flange. The guide plate is suspended below the conveyor plate chain and is inclined with the higher end facing outward, so as to receive the release agent dripping from the spraying station and guide it to the tank for recovery. The agitator is used to stir the release agent in the tank. The release agent in the tank is pumped to the nozzle through a delivery pipe with a delivery pump. The nozzle is connected to an external compressed air source through a compressed air pipe with a valve, and is suspended above the guide plate. The spraying direction is directly opposite to the open end of the passing mold.

[0016] The pouring mechanism includes a furnace body, an output pipe with a valve, the pouring head, and a switching mechanism for driving the pouring head to move. The switching mechanism includes a switching cylinder and a swing arm. The swing arm is V-shaped, and the tip is rotatably arranged on a mounting seat as a fixed component through a bearing. One end is hinged to the execution end of the switching cylinder, and the other end is hinged to the pouring head. When the switching cylinder is retracted and reset, the pouring head is in the initial position. When the switching cylinder is fully extended, the pouring head is driven to descend to the pouring position by the swing of the swing arm around the central axis of the bearing. The molten metal is input into the pouring head from the furnace body through the output pipe, and poured into the mold at the pouring station through the pouring port of the pouring head.

[0017] The pouring mechanism also includes a sensor and a flow meter. The sensor is used to detect the arrival signal of the mold at the spraying station and to control the start and stop of the switching cylinder. The flow meter is arranged at the pouring head and is used to detect the amount of metal solution input into the pouring head and to control the valve switch on the output pipe.

[0018] In the collecting mechanism, the dust cover assembly includes a top cover and a side cover, which are jointly arranged outside the conveying mechanism. The air duct forms two branches, which are respectively connected to the top cover and the side cover. The top cover is hoisted above the conveying mechanism, and the side cover is arranged on one side of the conveying mechanism perpendicular to the conveying direction.

[0019] The demoulding mechanism is installed as a whole on the demoulding stand. The transmission shaft is supported by a bearing and rotatably arranged on the demoulding stand. It is horizontally arranged, perpendicular to the conveying direction, one end of which is exposed outside the demoulding stand and coaxially mounted on the demoulding sprocket. A pair of demoulding cams is arranged on the shaft body, and a knocking hammer is configured corresponding to each demoulding cam. The bottom end of the knocking hammer is provided with a hammer head, and the side of the hammer head facing the mold is in an arc shape. The top of the knocking hammer is provided with a matching plate exposed upward, and the hammer body is rotatably installed on a transverse axis on the stand. The transverse axis is parallel to the transmission shaft and is located below the transmission shaft. The demoulding cam is located directly above the corresponding knocking hammer and is roughly a parallelogram structure. The two short sides are respectively rounded at the connection with the long side of the side with an obtuse angle, and are in an arc shape. The demoulding cam rotates 360° around the central axis of the transmission shaft as the transmission shaft rotates, and contacts with the matching plate of the knocking hammer in turn through the two short sides, so as to push the knocking hammer to swing back and forth around the central axis of the transverse axis along the conveying direction.

[0020] Compared with the prior art, the beneficial effects of the utility model are embodied in:

[0021] 1. Realize continuous casting production with high production efficiency;

[0022] According to the running track of the mold, a spraying station with a spraying mechanism, a pouring station with a pouring mechanism, and a demoulding station with a demoulding mechanism are sequentially arranged, and a collecting mechanism is arranged outside the conveying mechanism, so that each mold can be automatically sprayed with a demoulding agent at the spraying station as the conveying mechanism runs, and the metal solution is automatically poured at the pouring station. The metal ingot in the mold is loosened by knocking the mold at the demoulding station, and the metal ingot is automatically detached as the mold continues to turn over. In the whole process, the harmful gas generated in the production is timely and uniformly collected through the collecting mechanism, with a high degree of automation and high production efficiency.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] Please refer to Figures 1 to 7 The environmentally friendly continuous casting machine of this embodiment includes:

[0044] The conveying mechanism 1 is used for conveying the mold 2, and includes a driving sprocket 12 driven by a driving device 11, a driven sprocket 13, and a conveying plate chain 14 wound between the two sprockets. The tension of the conveying plate chain 14 is adjustable by a tensioning mechanism 7;

[0045] The mold 2 is provided with a plurality of molds 2 which are arranged on the conveying plate chain 14 at equal intervals along the conveying direction. Each mold 2 is conveyed by the conveying mechanism 1 and sequentially passes through the spraying station, the pouring station, and the demoulding station. The mold 2 is in a bucket structure and is open at one end facing outward in a direction perpendicular to the conveying plate chain 14.

[0046] The spraying mechanism 3 is independent of the conveying mechanism 1, and is arranged outside the conveying mechanism 1, at the spraying station, and is used to spray the release agent to the inner wall of each mold 2 passing through the spraying station through the spraying head 36, and the spraying direction of the spraying head 36 is facing the open end of the passing mold 2;

[0047] The pouring mechanism 4 is independent of the conveying mechanism 1 and is located at the pouring station. The open end of the mold 2 moves vertically upward to the pouring station and is located directly below the pouring head 44 of the pouring mechanism 4. The pouring head 44 of the pouring mechanism 4 can be reciprocated between the initial position and the pouring position. When in the initial position, it is suspended above the mold 2 with a gap between them. When it descends from the initial position to the pouring position, it is directly facing the open end of the mold 2 below, and is used to inject the metal solution into the mold 2.

[0048] The collecting mechanism 6 covers the conveying mechanism 1 and the spraying station and the pouring station on the conveying track together through the dust removal cover assembly. The dust removal cover assembly is connected to the dust removal fan 64 through the air duct 63. The dust removal fan 64 is used to absorb the harmful gas in the dust removal cover through the air duct 63.

[0049] The demoulding mechanism 5 is used for demoulding the ingot solidified in the mold 2. It is arranged on the outside of the conveying mechanism 1 and located at the demoulding station. It is provided with a power component, a transmission component, and an execution component. The power component is a demoulding sprocket 53 which forms a chain transmission structure with the driving sprocket 12 of the conveying mechanism 1 through a transmission chain 52 and rotates synchronously with the driving sprocket 12. The transmission component is a transmission shaft 54 ​​with a demoulding cam 55. The transmission shaft 54 ​​is coaxially assembled with the demoulding sprocket 53 and rotates synchronously with the demoulding sprocket 53. The demoulding cam 55 drives the execution component to swing back and forth between the striking position and the waiting position along the conveying direction. The execution component is a striking hammer 57. When in the waiting position, there is a spacing between it and the mold 2 running to the demoulding station along the conveying direction. The mold 2 at the demoulding station faces the striking hammer 57, and the hammer head 58 of the striking hammer 57 that swings to the striking position strikes the demoulding.

[0050] In a specific implementation, the corresponding structural setting of the continuous casting machine also includes:

[0051] The tensioning mechanism 7 includes a linear slide 71, a traction screw 72, a spring fixing seat 73, a spring pressure cover 74, a spring 75, and an adjusting nut 76, which are integrally installed on the frame of the conveying mechanism 1 and are located on the side where the driven sprocket 13 is located. The traction screw 72 is horizontally arranged along the conveying direction, one end of which is fixedly connected to the slider of the linear slide 71, and the other end of the traction screw 72 is cantilevered outside the frame and is sleeved with a spring 75. The deformation direction of the spring 75 is arranged along the conveying direction, and is tensioned between the spring pressure cover 74 on the traction screw 72 and the frame of the conveying mechanism 1. The position of the spring pressure cover 74 on the traction screw 72 is adjustable by an adjusting nut 76 threadedly mounted on the traction nut. The axle of the driven sprocket 13 of the conveying mechanism 1 is supported by a bearing on the slider of the linear slide 71 and can be displaced synchronously with the slide.

[0052] The tensioning degree of the conveyor plate chain 14 can be adjusted by the tensioning mechanism 7 by loosening the adjusting nut 76, and moving the slider along the conveying direction by pulling the screw 72. The displacement direction can be toward the conveying mechanism 1 or away from the conveying mechanism 1, depending on the tensioning requirements. The driven sprocket 13 is synchronously displaced with the slider. When the conveyor plate chain 14 is re-tensioned to the required degree, the adjusting nut 76 is re-tightened to form and maintain a tight fit against the spring pressure cover 74. With the help of the elastic force of the spring 75, the conveyor plate chain 14 can be further tensioned to a certain extent.

[0053] The mold 2 is a trapezoidal bucket structure, with the trapezoidal bottom serving as an open end.

[0054] The spraying mechanism 3 includes a release agent storage tank 31 with an agitator 33 and a release agent delivery pipe 34 for delivering the release agent in the tank to a nozzle 36. The release agent storage tank 31 is used to store the release agent, has an open top and extends toward the conveying mechanism 1 on the side facing the mold 2 to form a guide plate 32 with a flange. The guide plate 32 is suspended below the conveyor plate chain 14 and is inclined with the higher end facing outward. It is used to receive the release agent dripping from the spraying station and guide it to the tank for recovery. The agitator 33 is used to stir the release agent in the tank. The release agent in the tank is pumped to the nozzle 36 through a delivery pipe 34 with a delivery pump 35. The nozzle 36 is connected to an external compressed air source through a compressed air pipe 37 with a valve 42, which is suspended above the guide plate 32. The spraying direction is directly opposite to the open end of the passing mold 2.

[0055] In the spraying mechanism 3, the agitator 33 can be a stirring shaft with stirring blades driven to rotate by a stirring motor; at the spraying station, since the agitator 33 is provided, the release agent in the release agent storage tank 31 can be stirred as evenly as possible and pumped to the nozzle 36, and the release agent is sprayed onto the inner wall of the mold 2 facing the mold 2 by the nozzle 36. During the spraying process, the release agent will inevitably splash and drip, so a guide plate 32 is also provided below to receive these residual release agents and return them to the storage tank, which helps to maintain the production environment.

[0056] The pouring mechanism 4 includes a furnace body 41, an output pipe 43 with a valve 42, a pouring head 44, and a switching mechanism for driving the pouring head 44 to move. The switching mechanism includes a switching cylinder 45 and a swing arm 46. The swing arm 46 is V-shaped, and the tip is rotatably arranged on a mounting seat 47 as a fixed component through a bearing. One end is hinged to the execution end of the switching cylinder 45, and the other end is hinged to the pouring head 44. When the switching cylinder 45 is retracted and reset, the pouring head 44 is in the initial position. When the switching cylinder 45 is fully extended, the pouring head 44 is driven to descend to the pouring position by the swing arm 46 around the central axis of the bearing. The molten metal is input from the furnace body 41 into the pouring head 44 through the output pipe 43, and poured into the mold 2 at the pouring station through the pouring port of the pouring head 44.

[0057] The pouring mechanism 4 also includes a sensor 48 and a flow meter 49. The sensor 48 is used to detect the arrival signal of the mold 2 at the spraying station and to control the start and stop of the switching cylinder 45. The flow meter 49 is arranged at the pouring head 44 and is used to detect the amount of metal solution input into the pouring head 44 and to control the switch of the valve 42 on the output pipe 43.

[0058] The output pipe 43 is a high temperature resistant pipe.

[0059] At the pouring station, before preparing for pouring, the pouring head 44 is in the initial position, and the valve 42 on the output pipe 43 is closed. When the mold 2 is in place at the pouring station, the switching cylinder 45 is started, the piston rod is extended, and the swing arm 46 is driven to swing. The pouring head 44 is lowered toward the mold 2 at the pouring station with the swing of the swing arm 46, so that the pouring port is close to the open end of the mold 2. After that, the valve 42 of the output pipe 43 is opened, and the metal solution in the furnace body 41 is input into the pouring head 44 and poured into the mold 2 from the pouring port. During the process, the pouring amount of the metal solution is controlled by the flow meter 49, which is conducive to the stable control of the pouring amount each time. After pouring, the valve 42 is closed, and the switching cylinder 45 drives the pouring head 44 to reset, and the mold 2 continues to run with the conveying mechanism 1.

[0060] The purpose of setting the collecting mechanism 6 is to enable the harmful gases generated in the continuous casting production process to be collected in a timely and centralized manner.

[0061] In the collecting mechanism 6, the dust cover assembly includes a top cover 61 and a side cover 62, which are jointly arranged outside the conveying mechanism 1. The air duct 63 forms two branches, which are respectively connected to the top cover 61 and the side cover 62. The top cover 61 is hoisted above the conveying mechanism 1, and the side cover 62 is arranged on one side of the conveying mechanism 1 perpendicular to the conveying direction.

[0062] The demoulding mechanism 5 is integrally mounted on the demoulding stand 51. The transmission shaft 54 ​​is supported by a bearing and rotatably arranged on the demoulding stand 51. It is horizontally arranged and perpendicular to the conveying direction. One end is exposed outside the demoulding stand 51 and is coaxially mounted on the demoulding sprocket 53. A pair of demoulding cams 55 are arranged on the shaft body. A knocking hammer 57 is configured corresponding to each demoulding cam 55. The bottom end of the knocking hammer 57 has a hammer head 58. The hammer head 58 is arc-shaped on the side facing the mold 2. The top end of the knocking hammer 57 is provided with a matching plate 510 exposed upward. The hammer body is rotatably mounted on a horizontal axis 56 on the stand. The horizontal axis 56 is parallel to the mold 2. On the transmission shaft 54, located below the transmission shaft 54, the demoulding cam 55 is located just above the corresponding knocking hammer 57, and is roughly in a parallelogram structure. The two short sides are respectively rounded at the connection with the long side of the side with an obtuse angle, forming an arc shape. The demoulding cam 55 rotates 360° around the central axis of the transmission shaft 54 ​​as the transmission shaft 54 ​​rotates, and contacts with the matching plate 510 of the knocking hammer 57 in turn through the two short sides, pushing the knocking hammer 57 to swing back and forth around the central axis of the horizontal axis 56 along the conveying direction, so that a pair of knocking hammers 57 knock on both sides of the mold 2 located at the demoulding station along the width direction of the mold 2.

[0063] Furthermore, as the conveying mechanism 1 is conveyed, the mold 2 is turned 90° toward the conveying direction from the vertical upward posture of the open end, and arrives at the demoulding station, and the open end faces the hammer head 58 of the knocking hammer 57. The working process of the demoulding mechanism 5 is: as the driving sprocket 12 rotates, the demoulding sprocket 53 is driven to rotate synchronously, and the transmission shaft 54 ​​with the demoulding cam 55 also rotates synchronously with the driving shaft. During the rotation process, the demoulding cam 55 will rely on the two short sides to repeatedly collide with the matching plate 510 of the knocking hammer 57 in sequence. Under the push of the demoulding cam 55, the knocking hammer 57 will repeatedly swing back and forth around the central axis of the horizontal axis 56. Each time it swings toward the conveying mechanism 1, the hammer head 58 touches the open end of the mold 2 at the demoulding station, forming a knock on the mold 2, so that the metal ingot in the mold 2 is knocked loose. As the conveying mechanism 1 continues, when the mold 2 continues to flip, the metal ingot falls off under the action of its own weight.

[0064] Correspondingly, a receiving plate 59 for receiving the metal ingots may be provided below the conveying mechanism 1 , and the receiving plate 59 is used to guide the received metal ingots to a fixed position for uniform stacking by the robot.

[0065] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.

The sensor is used to detect the arrival signal of the mold at the spraying station and to control the start and stop of the switching cylinder. The flow meter is arranged at the pouring head and is used to detect the amount of metal solution input into the pouring head and to control the valve switch on the output pipe.

7. The environmentally friendly continuous casting machine according to claim 1 is characterized in that: In the collecting mechanism, the dust cover assembly includes a top cover and a side cover, which are jointly arranged outside the conveying mechanism. The air duct forms two branches, which are respectively connected to the top cover and the side cover. The top cover is hoisted above the conveying mechanism, and the side cover is arranged on one side of the conveying mechanism perpendicular to the conveying direction.

8. The environmentally friendly continuous casting machine according to claim 1 is characterized in that: The demoulding mechanism is installed as a whole on the demoulding stand. The transmission shaft is supported by a bearing and rotatably arranged on the demoulding stand. It is horizontally arranged, perpendicular to the conveying direction, one end of which is exposed outside the demoulding stand and coaxially mounted on the demoulding sprocket. A pair of demoulding cams is arranged on the shaft body, and a knocking hammer is configured corresponding to each demoulding cam. The bottom end of the knocking hammer is provided with a hammer head, and the side of the hammer head facing the mold is in an arc shape. The top of the knocking hammer is provided with a matching plate exposed upward, and the hammer body is rotatably installed on a transverse axis on the stand. The transverse axis is parallel to the transmission shaft and is located below the transmission shaft. The demoulding cam is located directly above the corresponding knocking hammer and is roughly a parallelogram structure. The two short sides are respectively rounded at the connection with the long side of the side with an obtuse angle, and are in an arc shape. The demoulding cam rotates 360° around the central axis of the transmission shaft as the transmission shaft rotates, and contacts with the matching plate of the knocking hammer in turn through the two short sides, so as to push the knocking hammer to swing back and forth around the central axis of the transverse axis along the conveying direction.
