Description

Technical Field

[0001] This utility model relates to the field of steel casting production technology, specifically a casting device for steel castings. Background Technology

[0002] Casting of steel parts refers to the safe and precise pouring of molten steel into a mold (such as a sand mold or metal mold) during the production of cast steel. It is mainly used to control the flow rate, direction and temperature of the molten steel to ensure the forming quality of the cast steel parts and avoid casting defects such as incomplete pouring, cold shuts, slag inclusions and porosity.

[0003] Chinese patent application number CN202220258455.3 discloses a ladle for casting steel parts, comprising a ladle body, an mounting ring fixedly connected to the lower end of the outer wall of the ladle body, two rotating seats fixedly connected to the outer wall of the mounting ring, a first roller rotatably connected to the rotating seats, the outer wall of the first roller being flush with the lower surface of the ladle body, a connecting ring fixedly connected to the upper end of the outer wall of the ladle body, a support rod rotatably connected to the outer wall of the connecting ring, an mounting seat fixedly connected to one end of the support rod, a second roller rotatably connected to the mounting seat, and an adjustment mechanism for adjusting the angle of the support rod between the support rod and the outer wall of the ladle body. This utility model has the advantage of facilitating the operator's movement and handling of the ladle.

[0004] In existing technologies, molten steel ladles must be in contact with the ground in order to change their angle using casters. However, in practical applications, the pouring methods for cast steel parts include top pouring, bottom pouring, intermediate pouring, and rain pouring, allowing for flexible and varied tilting angles and pouring positions to accommodate different types of cast steel parts. Contact with the ground limits the tilting range of the molten steel ladle, resulting in a limited scope of application and hindering its widespread adoption.

[0005] In summary, this utility model provides a casting device for steel castings to solve the above-mentioned problems. Utility Model Content

[0006] This invention provides a casting device for steel castings, which solves the problem of limited applicability in the prior art by expanding the tilting range of the molten steel ladle.

[0007] The specific technical solution of this utility model is as follows:

[0008] A casting device for steel casting includes a ladle, a rotating plate detachably connected to the lower part of the ladle, a first connecting plate fixedly connected to one side of the rotating plate, a second connecting plate disposed on one side of the first connecting plate, a first rotating shaft rotatably connected between the first and second connecting plates, a second rotating shaft rotatably connected to the side of the second connecting plate away from the first connecting plate, a third connecting plate rotatably connected to the end of the second rotating shaft away from the second connecting plate, a first driving cylinder disposed on the side of the first rotating shaft, the output end of the first driving cylinder rotatably connected to the first rotating shaft, a transmission plate rotatably connected to the side of the second rotating shaft, an extension plate fixedly connected to one side of the transmission plate, a third rotating shaft rotatably connected to one side of the extension plate, a second driving cylinder disposed on the side of the third rotating shaft, the output end of the second driving cylinder rotatably connected to the third rotating shaft.

[0009] In this invention, the ladle is used to hold molten steel and other materials, and the rotating plate is used to load and unload the ladle and adjust its angle to pour out the material for casting. The transmission plate and the second rotating shaft essentially move the overall position of the rotating plate through the second driving cylinder, making it easier to move the ladle near the mold. The first rotating shaft essentially changes the angle of the rotating plate through the first driving cylinder. When the second driving cylinder is stationary, the positions of the transmission plate and the second rotating shaft are relatively fixed. When the output end of the first driving cylinder extends or shortens, it applies a pushing or pulling force to the rotating plate, thereby causing the rotating plate to rotate around the second rotating shaft. This solves the problem in the prior art that the molten steel ladle must be in contact with the ground to obtain a support point for rotation.

[0010] In a preferred embodiment, a limiting ring is fixedly connected to the side of the rotating plate near the ladle.

[0011] In this invention, the limiting ring is used to enhance the stability of the connection between the rotating plate and the ladle, so that the ladle is not easily detached from the rotating plate when tilted.

[0012] In a preferred embodiment, the ladle is provided with a gating gate on its side.

[0013] In this invention, the gate is used to align with the interface on the mold and pour out the material from the ladle for pouring.

[0014] In a preferred embodiment, the ladle is provided with a top cover, and a lifting ring rod is provided on the side of the top cover, with the bottom end of the lifting ring rod rotatably connected to the ladle.

[0015] In this invention, the top cover is used to improve the safety performance of the ladle and prevent material from flowing out from the top when it is poured.

[0016] In a preferred embodiment, a hook is provided above the lifting ring rod, a traction rope is fixedly connected to the top of the hook, a bracket is fixedly connected to the top of the traction rope, and the bottom of the bracket is fixedly connected to the rotating plate.

[0017] In this invention, the lifting ring rod and hook are used to improve the stability and safety of the ladle when it is tilted, and to avoid safety problems such as the ladle falling off when it is tilted.

[0018] In a preferred embodiment, a control frame is rotatably connected to the top of the first drive cylinder, the top of the transmission plate is rotatably connected to the control frame, and the top of the second drive cylinder is rotatably connected to the control frame.

[0019] In this invention, the control frame is used to control the movement of the first and second drive cylinders on the one hand, and to connect and move the overall structure on the other hand, thereby further expanding the movement range of the ladle.

[0020] In a preferred embodiment, a first robotic arm is fixedly connected to the top of the control frame.

[0021] In this invention, the first robotic arm is essentially used for lifting and controlling the frame.

[0022] In a preferred embodiment, a second robotic arm is rotatably connected to the side of the first robotic arm.

[0023] In this invention, the second robotic arm essentially causes the first robotic arm to rotate relative to the third robotic arm.

[0024] In a preferred embodiment, a third robotic arm is rotatably connected to the side of the second robotic arm away from the first robotic arm.

[0025] In this invention, the third robotic arm essentially rotates the second robotic arm relative to the fourth robotic arm, and the length of the third robotic arm is used to expand the movement range of the ladle.

[0026] In a preferred embodiment, a fourth robotic arm is rotatably connected to the side of the third robotic arm away from the second robotic arm.

[0027] In this invention, the fourth robotic arm is fixedly installed near the mold to provide a support point for the ladle when it moves flexibly, and the installation position of the fourth robotic arm can be freely selected.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. This utility model, by setting a rotating plate below the ladle and utilizing a first driving cylinder, a second driving cylinder, a first rotating shaft, a second rotating shaft, and other structures, allows the rotating plate to flexibly adjust the angle and overall position of the ladle. This solves the problem in the prior art that the molten steel ladle must be in contact with the ground to obtain a support point for rotation. The ladle angle can be changed and its position moved without ground support, thus improving the flexibility and convenience of the pouring operation.

[0030] 2. This utility model enhances the stability of the connection with the ladle by using a limiting ring on the rotating plate, preventing the ladle from detaching from the rotating plate when tilted, thus ensuring the safety of the pouring process.

[0031] 3. This utility model can prevent materials from flowing out from the top when tilting by using the top cover, thus improving safety performance. The cooperation of the lifting ring rod, hook, traction rope, and bracket further enhances the stability of the ladle when tilting, preventing safety issues such as falling off.

[0032] 4. This utility model forms a multi-axis motion structure by combining a first robotic arm, a second robotic arm, a third robotic arm, and a fourth robotic arm. The first robotic arm can lift and lower, the second and third robotic arms can rotate and expand the range of movement by utilizing their length, and the fourth robotic arm is fixed near the mold to provide a flexible support point, allowing the ladle to move flexibly in three-dimensional space to adapt to molds in different positions, thereby improving the versatility and pouring efficiency of the device. Furthermore, the installation position of the fourth robotic arm can be freely selected, enhancing the adaptability of the device to different working environments. Attached Figure Description

Detailed Implementation

[0039] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0040] like Figure 1-5 As shown, this utility model provides a casting device for steel castings, including a ladle 1. A rotating plate 2 is detachably connected to the lower part of the ladle 1. A first connecting plate 22 is fixedly connected to one side of the rotating plate 2. A second connecting plate 23 is provided on one side of the first connecting plate 22. A first rotating shaft 24 is rotatably connected between the first connecting plate 22 and the second connecting plate 23. A second rotating shaft 25 is rotatably connected to the side of the second connecting plate 23 away from the first connecting plate 22. A third connecting plate 26 is rotatably connected to the end of the second rotating shaft 25 away from the second connecting plate 23. A first driving cylinder 3 is provided on the side of the first rotating shaft 24. The output end of the first driving cylinder 3 is rotatably connected to the first rotating shaft 24. A transmission plate 4 is rotatably connected to the side of the second rotating shaft 25. An extension plate 41 is fixedly connected to one side of the transmission plate 4. A third rotating shaft 42 is rotatably connected to one side of the extension plate 41. A second driving cylinder 5 is provided on the side of the third rotating shaft 42. The output end of the second driving cylinder 5 is rotatably connected to the third rotating shaft 42.

[0041] A limit ring 21 is fixedly connected to the side of the rotating plate 2 closest to the ladle 1.

[0042] A gating gate 11 is provided on the side of the ladle 1.

[0043] The top of the ladle 1 is provided with a top cover 12, and the side of the top cover 12 is provided with a lifting ring rod 13, the bottom end of the lifting ring rod 13 being rotatably connected to the ladle 1.

[0044] A hook 14 is provided above the lifting ring rod 13. A traction rope 15 is fixedly connected to the top of the hook 14. A bracket 16 is fixedly connected to the top of the traction rope 15. The bottom of the bracket 16 is fixedly connected to the rotating plate 2.

[0045] The top of the first drive cylinder 3 is rotatably connected to the control frame 6, the top of the transmission plate 4 is rotatably connected to the control frame 6, and the top of the second drive cylinder 5 is rotatably connected to the control frame 6.

[0046] The first robotic arm 7 is fixedly connected to the top of the control frame 6.

[0047] The second robotic arm 8 is rotatably connected to the side of the first robotic arm 7.

[0048] The second robotic arm 8 is rotatably connected to the third robotic arm 9 on the side away from the first robotic arm 7.

[0049] The third robotic arm 9 is rotatably connected to the fourth robotic arm 10 on the side away from the second robotic arm 8.

[0050] The working principle of this invention is as follows: When the tilt angle of the ladle 1 needs to be adjusted, the output end of the first drive cylinder 3 extends or shortens, pushing or pulling the first rotating shaft 24, causing the first connecting plate 22 and the second connecting plate 23 to be subjected to force from the first rotating shaft 24. Since the second connecting plate 23 is rotatably connected to the second rotating shaft 25, and the second drive cylinder 5 does not move, restricting the movement of the second rotating shaft 25, the first connecting plate 22 and the second connecting plate 23 rotate relative to the second rotating shaft 25, thereby causing the rotating plate 2 to rotate around the second rotating shaft 25, thus tilting the ladle 1 and pouring molten steel into the mold through the pouring gate 11. This process does not require the ladle 1 to contact the ground, solving the problem of traditional molten steel ladles relying on ground support for rotation.

[0051] When the output end of the second drive cylinder 5 extends or retracts, it pushes the extension plate 41 and the transmission plate 4 to move via the third rotating shaft 42. The transmission plate 4 is rotatably connected to the second rotating shaft 25, thus driving the second rotating shaft 25 and the rotating plate 2 to move as a whole, so that the ladle 1 moves closer to or further away from the mold, making it easier to align with the position of the gate 11.

[0052] The limiting ring 21 on the rotating plate 2 locks the bottom of the pouring ladle 1, enhancing the connection stability between the pouring ladle 1 and the rotating plate 2 and preventing the pouring ladle 1 from detaching during tilting.

[0053] The top cover 12 of the ladle 1 can prevent molten steel from overflowing from the top when it is poured; the lifting ring rod 13 is connected to the bracket 16 through the hook 14 and the traction rope 15 to form a flexible traction structure, which provides tensile support when the ladle 1 is tilted, preventing the ladle 1 from falling off due to the shift of the center of gravity and improving safety.

[0054] The control frame 6 serves as the central structure, connecting the first drive cylinder 3, the second drive cylinder 5, and the transmission plate 4. By controlling the movements of these two components, it coordinates the angle and position of the ladle 1. Simultaneously, the first robotic arm 7 above the control frame 6 can achieve vertical lifting and lowering movements, while the second robotic arm 8 and the third robotic arm 9 expand their horizontal movement range through rotating joints. The fourth robotic arm 10 (fixed near the mold) provides a support point for the entire robotic arm system, forming a multi-axis linkage robotic arm group. The ladle 1 can move flexibly in three-dimensional space to adapt to molds in different positions, and the installation position of the fourth robotic arm 10 can be freely selected, enhancing the device's adaptability to complex working environments.

[0055] The ladle 1 and the rotating plate 2 are detachably connected, making it easy to replace ladle 1 with different specifications to meet diverse pouring needs.
