[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] A super-helical centrifugal casting device includes a disc 1, and the material of the disc 1 can be selected according to actual needs to ensure sufficient strength and rigidity. A driving mechanism 2 is provided on each side of the disc 1, and the driving mechanism 2 is a motor. The two driving mechanisms 2 are located on both sides of the axial direction of the disc 1, and the driving mechanisms 2 are connected to the mounting blocks 3, and the mounting blocks 3 are connected to the ropes 4, and the ropes 4 are connected to the disc 1. The two driving mechanisms 2 can drive the two mounting blocks 3 to be relatively close or far away, and the ropes 4 located between the disc 1 and the mounting blocks 3 form a super-helical structure, which converts the elastic potential energy into the rotational kinetic energy of the disc 1, thereby driving the disc 1 to rotate. As the number of reciprocating times of the rope 4 increases, the rotation speed of the disc 1 gradually increases until it reaches a predetermined high rotation speed state.

[0025] A buckle 5 is fixedly arranged on the side of the disc 1, and a casting mold 6 is installed in the buckle 5. The centrifugal force generated by the rotation of the disc 1 is sufficient to make the molten metal evenly distributed in the buckle 5 and solidify quickly.

[0026] The device also includes a control system, which controls the driving mechanism 2 and is used to adjust the movement distance and frequency of the rope 4 to control the rotation speed of the disc 1.

[0027] Two ropes 4 are connected to each of the two mounting blocks 3 , one end of the two ropes 4 away from the mounting blocks 3 is connected to the side of the disc 1 , and the ends of the two ropes 4 connected to the mounting blocks 3 are connected to each other.

[0028] like Figure 2 As shown, two through holes 7 are provided on the disc 1, and two ropes 4 are connected between the two mounting blocks 3. The two ropes 4 are respectively passed through the two through holes 7, and the ends of the two ropes 4 are connected to the ends of the other ropes 4. The two through holes 7 are symmetrically arranged, and the line connecting the centers of the two through holes 7 passes through the center of the disc 1, and the distances from the centers of the two through holes 7 to the center of the disc 1 are the same.

[0029] like Figure 1 As shown, the disc 1 is arranged vertically, and a support block 8 is arranged below the driving mechanism 2, the support block 8 supports the driving mechanism 2, and a slide rail 9 is arranged on the support block 8. The mounting block 3 is slidably arranged on the slide rail 9, and the movement of the mounting block 3 is guided by the slide rail 9, so that the mounting block 3 moves in the horizontal direction.

[0030] like Figure 3As shown, the disc 1 is arranged horizontally, and a bearing 10 is arranged below the disc 1, and the disc 1 is rotatably arranged on the bearing 10. The bearing 10 is a ball bearing, and the bearing 10 supports the disc 1 to achieve smooth rotation of the disc 1. The device also includes a support frame 11, and two sections of the support frame 11 are provided with fixed blocks 13, and the driving mechanism 2 is installed on the side of the fixed block 13. The fixed block 13 is provided with a slide rail 9, and the mounting block 3 is slidably arranged on the slide rail 9 to ensure the vertical movement of the mounting block 3. The support frame 11 is also connected to a support seat 12, and the bearing 10 is installed on the support seat 12.

[0031] A method for using a super spiral centrifugal casting device comprises the following steps:

[0032] Pour the molten metal into the casting mold 6. The gate position of the casting mold 6 is sealed and installed on the disc 1 to prevent the molten metal from flowing out when the initial rotation speed is slow. Manually rotate the disc 1 so that the rope 4 forms a spiral structure. Subsequently, the drive mechanism 2 drives the mounting block 3 to reciprocate so that the rope 4 forms a super-helical structure, and the rope 4 drives the disc 1 to rotate to a predetermined speed. The disc 1 rotates at a predetermined speed for a period of time so that the molten metal is evenly distributed in the casting mold 6 and solidifies quickly. Turn off the drive mechanism 2 to stop the rotation of the disc 1, remove the casting mold 6 from the disc 1, and take out the casting from the casting mold 6 after cooling for subsequent processing.

[0033] Table 1 shows the equipment data for castings of the same weight and size

[0034] Parameters Conventional centrifugal casting machine Super spiral centrifugal casting device Time required to reach 1000r / min / s 30 10 Maximum speed / r / min 1000 30000 Main motor power / KW 5 5 Is the speed controllable? yes no

[0035] It can be seen from Table 1 that when the power of the main motor of the driving mechanism is the same, the super spiral centrifugal casting device reaches a high speed faster than the traditional centrifugal casting machine and can reach a higher speed.

[0036] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
