Description

Technical fields:

[0001] This application relates to the field of auxiliary devices for liquid metal casting, and in particular to a liquid metal casting device for rare earth smelting. Background technology:

[0002] Molybdenum crucibles are metallurgical equipment made from Mo-1 molybdenum powder. They operate at temperatures between 1100℃ and 1700℃ and are mainly used in the metallurgical industry, rare earth industry, monocrystalline silicon, solar energy, artificial crystals, and machining industries.

[0003] When used in the rare earth industry, molten metal is placed in a molybdenum crucible. Workers use clamps to lift the crucible and transfer it to one side of the mold. Then, they rotate the clamps to pour the molten metal from the crucible into the mold. Because the molybdenum crucibles used in the rare earth industry are large and heavy after being filled with molten metal, both hands need to apply a large inward force during the transfer process to ensure the stability of the crucible during movement. Furthermore, the center of gravity is close to the crucible after clamping, requiring a large upward lifting force to maintain stability during movement. This results in high labor intensity and fatigue after prolonged work, leading to unstable clamping. Utility Model Content:

[0004] To solve the above-mentioned technical problems, this utility model provides a rare earth smelting liquid metal casting device. The technical problem it addresses is that during the transfer of a molybdenum crucible using a double-clamping crucible clamp, the worker's workload is high, and prolonged work can easily lead to fatigue and unstable clamping. To solve this problem, the technical solution adopted by this utility model is as follows:

[0005] A rare earth smelting liquid metal casting apparatus, characterized in that it comprises:

[0006] Rod A, one end of rod A is provided with a fixed clamping claw in a fixed structure manner;

[0007] The movable gripper is hinged to the rod A on one side of the fixed gripper.

[0008] The connecting rod has one end connected to the movable gripper via a hinge structure.

[0009] The slider is connected to the other end of the connecting rod by a hinge structure, and the slider is located inside the rod A;

[0010] Brake cable, which is connected to the slider to drive the slider to move within rod A;

[0011] Brake lever, the brake lever is connected to the other end of the brake cable;

[0012] Link B is connected to the brake lever in a fixed manner, and one end of link B is connected to link A in a rotating manner.

[0013] Furthermore, a through groove is provided inside the movable gripper, and the side wall of the through groove is connected to the rod A in a hinged structure.

[0014] Furthermore, a groove is provided on the side wall of rod A for connecting the slider to the connecting rod.

[0015] Furthermore, a sleeve is fixedly installed inside member A, and the sleeve is fitted over the brake cable.

[0016] A return spring is installed on the outside of the brake line between the sleeve and the slider.

[0017] Furthermore, an anti-slip sleeve A is fitted onto the outside of the lever A on one side of the brake lever.

[0018] Furthermore, the rod B is fitted with an anti-slip sleeve B.

[0019] Furthermore, a fixing sleeve is fixedly installed inside the member A on the side closest to member B;

[0020] Rod B passes through the fixed sleeve, and limiting pads are fitted on the outside of rod B on both sides of the fixed sleeve.

[0021] Furthermore, member A is a square tube structure.

[0022] The beneficial effects of this utility model are: by setting a brake lever, when in use, the worker grips the brake lever with his right hand, and the brake lever moves the connecting rod through the brake cable, which in turn drives the movable jaw to move towards the fixed jaw. Through the lever principle, the molybdenum crucible can be clamped with a small amount of hand gripping force.

[0023] After clamping, the left hand grips rod A as the fulcrum of the lever, while the right hand presses the tail down to make it easier to lift the molybdenum crucible and pour the molten metal into the mold. The right wrist, which is closer to the torso, does not need to be rotated. The molybdenum crucible can be tilted by rotating rod A with the left hand, which is further away from the torso, to complete the pouring work. This is more in line with ergonomic design and reduces the labor intensity of the right wrist. Attached image description:

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0029] A rare earth smelting liquid metal casting device includes a rod A1. A fixed gripper 2 is fixedly mounted at one end of rod A1. A movable gripper 3 is hinged to one side of rod A1. The movable gripper 3 is connected to a connecting rod 4 via the hinge. A slider 5 is hinged to the other end of connecting rod 4. The slider 5 is slidably mounted inside rod A1 and connected to a brake cable 6 to drive it to move within rod A1. The other end of the brake cable 6 is connected to a brake lever 7. The brake lever 7 is fixedly connected to a rod B8, one end of which is rotatably connected to rod A1. By using the brake lever 7, when the worker grips it with their right hand, the brake lever 7 pulls the connecting rod 4 via the brake cable 6, thereby moving the movable gripper 3 towards the fixed gripper 2. Through the lever principle, the molybdenum crucible can be clamped with relatively little hand gripping force, making it more labor-saving.

[0030] It should be noted that, in order to prevent the movable gripper 3 from opening and closing excessively and affecting its use, a through groove 9 is provided inside the movable gripper 3, and the side wall of the through groove 9 is connected to the rod A1 in a hinged structure.

[0031] It should be noted that the side wall of the rod A1 is provided with a groove 10 for the connecting rod 4 to connect to the slider 5, so as to avoid the connecting rod A1 interfering with the movement of the connecting rod 4.

[0032] Specifically, a sleeve 11 is fixedly installed inside the rod A1. The sleeve 11 is sleeved on the outside of the brake line 6. A return spring is installed on the outside of the brake line 6 between the sleeve 11 and the slider 5 to reset the slider 5 pulled by the brake line 6, thereby opening the gripper.

[0033] To prevent slippage, the lever A1 on one side of the brake lever 7 is fitted with an anti-slip sleeve A12, and the lever B8 is fitted with an anti-slip sleeve B13.

[0034] In order to ensure that the rod A1 and the rod B8 can be rotated when they are integrated, a fixing sleeve 14 is fixedly installed inside the rod A1 near the rod B8. The rod B8 passes through the fixing sleeve 14, and limiting pads 15 are fitted on the outside of the rod B8 on both sides of the fixing sleeve 14.

[0035] The rod A1 is designed with a square tube structure, making it easy to grip and rotate the rod A1 with the left hand.

[0036] The working principle and process of this utility model are as follows:

[0037] The worker holds the tail of the pressure rod B with his right hand and the rod A1 with his left hand. He places the fixed clamp 2 and the movable clamp 3 outside the molybdenum crucible. Then, the worker grips the brake lever 7 with his right hand. The brake lever 7 pulls the slider 5 through the brake cable 6. The slider 5 drives the movable clamp 3 to move towards the fixed clamp 2 through the connecting rod 4, thus clamping the molybdenum crucible.

[0038] Then, the right hand, which is closer to the body, presses down on the tail of rod B, while the left hand, which is farther away from the body, lifts up rod A1 to pick up the molybdenum crucible and move it to the mold. Then, the left hand rotates rod A1, which in turn tilts the molybdenum crucible and pours the molten metal into the mold, completing the casting process.
