Description

Technical Field

[0001] The invention relates to the technical field of metal casting, in particular to a metal casting device in a rare earth molten salt electrolysis process. Background Art

[0002] The metal casting methods in the current rare earth molten salt electrolysis process are generally:

[0003] 1. Manual pouring: the operator uses pliers to pour the metal in the crucible into the mold. This method is labor-intensive for the operator. Improper operation may cause the metal liquid to splash, posing the risk of scalding the operator.

[0004] 2. Siphon pouring: Use a siphon device to suck the molten metal in the crucible into the mold. The titanium tube in this method cannot be fully preheated and is easily blocked by metal;

[0005] 3. Mechanical automatic pouring: Place the crucible containing the molten metal on the pouring device, turn the crucible directly over through a mechanical device, and pour it into the mold. A large number of metal beads will form at the bottom of the metal poured by this method, making it difficult to strip the metal and causing the surface to deteriorate.

The two guide wheel devices are respectively slidably connected to the two slide rails along the horizontal direction.

[0014] Preferably, the upper end surface of the movable frame is symmetrically fixed with two fixed side plates by hexagon socket cylindrical head screws, and the two fixed side plates are fixedly installed with cylinder seats by bolts on one end surface close to each other, and the two cylinder seats are fixedly installed with cylinders on one end close to each other, and a positioning head is fixedly connected to the cylinder output end, and an iron plate C is installed on the positioning head by clamp feet.

[0015] Preferably, the outer end surfaces of the first reduction motor and the second reduction motor are both equipped with dustproof boxes, and the dustproof boxes are fixedly installed on the supporting cross plate.

[0019] Preferably, the angle sensor is electrically connected to a PLC controller, and the PLC controller is electrically connected to an alarm and a control panel.

[0020] The beneficial effects of the present invention are:

[0021] 1. The casting mold is placed on the casting mold moving module through the metal casting device in the rare earth molten salt electrolysis process. When the crucible containing the molten metal is placed on the casting table, the cylinder, the first reduction motor and the second reduction motor are controlled through the control panel. The cylinder can drive the positioning head. The two positioning heads move toward each other to clamp and position the crucible on the casting table. Then the second reduction motor is started to drive the movable frame to rotate, so that the molten metal in the crucible can be poured into the casting mold.

[0022] 2. Through the metal pouring device in the rare earth molten salt electrolysis process, during the pouring process, the second reduction motor works to drive the screw to rotate, and the rotating screw can drive the pouring mold moving module to move horizontally, so that the pouring mold can be driven horizontally. After the crucible rotates to the set angle, the first reduction motor reverses to rotate the crucible to the initial position, and then the gas rod retracts to release the crucible. After the metal in the pouring mold solidifies, the second reduction motor reverses to move the pouring mold to the initial position.

[0023] 3. Through the metal pouring device in the rare earth molten salt electrolysis process, first set a preset value X for the PLC controller according to the angle at which the crucible needs to rotate. When the crucible is adjusted, the rotating shaft starts to rotate. The angle sensor can collect the rotation angle information of the rotating shaft and transmit it to the PLC controller. The PLC controller converts the angle information into data. When the data is equal to the preset value X, it means that the rotating shaft has rotated to a suitable angle. The PLC controller can send instructions to the second reduction motor and the alarm. The second reduction motor stops working and the alarm works to remind the operator.

[0024] 4. Through the metal pouring device in the rare earth molten salt electrolysis process, the pouring table design in the metal pouring device is offset to the back of the axis of the rotating shaft, which reduces the vertical height difference between the crucible and the mold during pouring, reduces the drop of the molten metal into the pouring mold, and reduces the generation of metal beads at one end of the bottom of the metal after pouring.

[0025] 5. Through the metal pouring device in the rare earth molten salt electrolysis process, a pouring mold moving module is added. During the crucible flipping pouring process, the pouring mold moving module cooperates to make corresponding movements, which can greatly reduce the number of metal beads generated at the bottom of the metal after pouring.

[0026] 6. The metal pouring device in the rare earth molten salt electrolysis process can be used to simulate human behavior and action operations. By controlling the coordinated movement of the pouring mold moving module and the crucible with a rotating function, actions similar to manual pouring can be achieved. After a large number of tests and adjustments, the crucible rotation angle of 95-100 degrees, the rotation angular velocity of 0.1-2.5rad / s, the start interval time of the crucible rotation and the pouring mold moving module of 0.2-3s, the moving distance of the pouring mold moving module of 1-30cm, and the moving speed of the pouring mold moving module of 1-20cm / s were selected. The cast metal has good molding and fewer metal beads.

[0027] The present invention uses a mechanical pouring device instead of manual labor to pour metal, thereby reducing the labor intensity of operators. Operators do not directly participate in the pouring of metal, avoiding the risk of being scalded. The pouring table in the metal pouring device is designed to be offset to the back of the axis of the rotating shaft, which can reduce the vertical height difference between the pouring mold and the crucible during pouring, reduce the drop of the molten metal into the pouring mold, and reduce the generation of metal beads at one end of the bottom of the metal after pouring. In the prior art, the crucible is directly turned over and poured into the pouring mold, and a large number of metal beads are generated at one end of the bottom of the metal. The present invention adds a pouring mold moving module. During the crucible flipping and pouring process, the pouring mold moving module cooperates to make corresponding movements, which can greatly reduce the number of metal beads generated, and the pouring mold movement and crucible flipping speeds are both adjustable. The present invention adopts a double-cylinder crucible clamping design, the cylinder extension and contraction speed is adjustable, the crucible clamping process is smooth and gentle, and the metal liquid shakes slightly.

[0049] The present invention has the following characteristics:

[0050] 1. The pouring table 12 in the metal pouring device is designed to be offset to the rear of the axis of the rotating shaft 7, which reduces the vertical height difference between the crucible and the pouring mold 16 during pouring, reduces the drop of the molten metal into the pouring mold 16, and reduces the generation of metal beads at one end of the bottom of the metal after pouring.

The angle sensor 1405 can collect the rotation angle information of the rotating shaft 7 and transmit it to the PLC controller 1406. The PLC controller 1406 converts the angle information into data. When the data is equal to the preset value X, it means that the rotating shaft 7 has rotated to a suitable angle.
