[0002] At present, permanent magnet alloys are a type of magnetic materials, generally divided into hard magnetic alloys and soft magnetic alloys. Permanent magnet alloys refer to magnetic alloys that can still retain a relatively high residual magnetism after being magnetized and when the external magnetic field is removed.

[0003] During the production process of permanent magnet alloys, a melting furnace is required for processing. There is a crucible inside the melting furnace. Pouring out the molten metal inside the crucible is rather troublesome and dangerous. Therefore, a turning device is needed to assist in the work.

[0004] In the prior art, the authorized announcement number is: CN212070369U, and the name is a crucible turning device. This device has a simple structure and is easy to operate. It can reliably fix and quickly turn the crucible on the annular baffle, realize the rapid pouring out of the molten metal in a short time, reduce the labor intensity of the operator and the residue of the molten metal in the crucible, improve the cleaning efficiency and cleaning quality after the crucible is used, ensure the long-term cyclic use of the crucible, and has good practical value. However, in actual application, the existing turning devices are generally rather troublesome to install the crucible, require a lot of time, and are relatively dangerous when staying beside the crucible for a long time, which will affect the work efficiency of the staff and reduce the practicability of the device. Content of the Utility Model

[0027] See Figures 1 to 2 , through the support plate 1 and the support frame 2, the crucible body 3 can be supported. There is molten metal inside the crucible body 3, so the weight of the crucible body 3 is relatively large. Therefore, the support frame 2 will bear a relatively large weight. Therefore, the support frame 2 needs to be made of a material with a relatively high hardness, which can bear a relatively large weight without breaking, and can effectively increase the service life and safety of the device.

[0028] Two reinforcing rods 9 are arranged above the support plate 1, and both ends of the reinforcing rods 9 are fixedly connected to the inner wall of the support frame 2. Through the reinforcing rods 9, the stability of the support frame 2 can be increased, and the support frame 2 can be prevented from being damaged under a relatively large external force, and the stability and safety of the device can be effectively increased.

[0029] The connection between the reinforcing rod 9 and the support frame 2 is fixed by welding, which can effectively prevent the reinforcing rod 9 from detaching from the support frame 2 and can effectively increase the safety of the device.

[0030] Four fixing blocks 10 are fixedly connected to the outer surface of the support plate 1. A bolt 11 is threadedly connected to the inner wall of the fixing block 10. The device can be installed at a required position through the fixing block 10 and the bolt 11, which can effectively prevent the device from shaking during use and can effectively improve the stability of the device.

A baffle 407 for limiting the limiting ball 404 is fixedly connected to the outer surface of the moving column 406.

[0037] See Figures 1 to 4 , by moving the sliding sleeve 405, the moving column 406 can be driven to move, and then the baffle 407 can be driven to move, and thus the limitation on the limiting ball 404 can be released.

[0038] The connecting rod 403 can be preliminarily limited by the limiting ball 404, and the limiting ball 404 can be limited by the sliding sleeve 405, the moving column 406 and the baffle 407, so that the sliding of the limiting ball 404 can be avoided during the rotation of the device, and the safety of the device can be effectively increased.

[0039] A telescopic spring 408 for automatically resetting the moving column 406 is fixedly connected to the outer surface of the moving column 406.

[0043] Refer to Figures 1 to 3 , the sliding sleeve 405 can be limited by the fixed seat 409 and the insertion rod 4010, the shaking of the sliding sleeve 405 during the use of the device can be effectively avoided, the safety during the operation of the device can be effectively increased, the sliding sleeve 405 is made of a material with higher hardness and can withstand greater external forces without breaking, and the service life of the device can be increased.

[0044] A pulling disc 6 is fixedly connected to the outer surface of the insertion rod 4010. The outer surface of the pulling disc 6 is passivated. The pulling disc 6 can make it more convenient and fast for the staff to pull the insertion rod 4010, and the passivation treatment on the outer surface of the pulling disc 6 can avoid the staff's palm being scratched.

The elastic force generated when the return spring 7 deforms can drive the pull plate 6 to automatically reset, which can reduce the operation difficulty of the device and make it more convenient for the staff to operate the device.

[0047] The return spring 7 has a large elastic coefficient, which can enable the device to have sufficient elastic force to drive the pull plate 6 to reset. At the same time, it can prevent the return spring 7 from being damaged by a large external force, which can increase the safety of the device.

[0048] A forward and reverse motor 8 is fixedly connected to the left side surface of the support frame 2. The output end of the forward and reverse motor 8 is fixedly connected to the left end of the left rotating shaft 401 among the two rotating shafts 401.

[0049] The forward and reverse motor 8 can be disassembled from the support frame 2, and different forward and reverse motors 8 can be replaced according to needs, so that the device can meet different usage requirements.

[0050] The specific implementation process of the present utility model is as follows: When the device is used, first, the connecting sleeve 402 needs to be loosened, and then the connecting sleeve 402 is moved. When the connecting rod 403 contacts the rotating shaft 401, the insertion rod 4010 is pulled, and then the limit on the sliding sleeve 405 can be released. When the sliding sleeve 405 is moved, the movement of the sliding sleeve 405 can drive the moving column 406 to move, and then drive the baffle 407 to move, and then the limit on the limit ball 404 can be released. Then, the connecting sleeve 402 is moved, and the limit ball 404 can be stuck into the inside of the connecting rod 403. Then, the sliding sleeve 405 is released, and the elastic force generated when the telescopic spring 408 deforms can make the moving column 406 automatically reset, and then the limit on the limit ball 404 can be realized. Then, the insertion rod 4010 is inserted into the sliding sleeve 405, and then the limit on the sliding sleeve 405 can be realized, so as to prevent the limit ball 404 from shaking, and then the installation of the crucible body 3 can be realized. Then, the forward and reverse motor 8 is started, and the forward and reverse motor 8 can drive the rotating shaft 401 to rotate, and then drive the crucible body 3 to rotate through the connecting rod 403, so as to achieve the purpose of flipping the crucible body 3.
