[0002] Wear-resistant steel balls, also known as wear-resistant media for grinders, are consumables. Their main purpose is to grind materials to make them finer to meet the usage standards. They are mainly used in fields such as mines, power plants, cement plants, steel plants, silica sand plants, and coal chemical industries. In addition, wear-resistant steel balls are important basic components, especially precision industrial steel balls play a huge role in the development of the national economy. Under some special conditions, steel balls of special materials are often required to complete the functions required in different environments. Before use, wear-resistant steel balls need to be rounded, and the burrs on the surface of the steel balls are ground off to make them smooth.

[0003] In the existing rounding devices for wear-resistant steel balls, after the grinding balls are clamped and fixed by a fixture, a polishing grinding wheel is then used to grind off the burrs on their surfaces. This will cause the clamped parts of the wear-resistant steel balls to be unable to be rounded, and only one steel ball can be rounded at a time, thus affecting the processing efficiency of the wear-resistant steel balls.

[0021] Combined with Figures 1 to 5 , it is a schematic structural view of an embodiment of a rounding device for producing wear-resistant steel balls of the present utility model. The rounding device for producing wear-resistant steel balls includes a chassis 1 and a carrying platform 2 fixedly arranged at the center of the inner bottom surface of the chassis 1. A lower grinding disc 3 is fixedly arranged on the top surface of the carrying platform 2, and an upper grinding disc 4 cooperating with the lower grinding disc 3 is rotatably arranged directly above the lower grinding disc 3;

[0022] The upper grinding disc 4 is composed of a disc 41, a first annular slide rail 42 and a second annular slide rail 43. The first annular slide rail 42 is fixedly sleeved on the outer wall of the disc 41, and the second annular slide rail 43 is fixedly sleeved on the outer wall of the first annular slide rail 42;

[0023] A plurality of first ball placement grooves 31 corresponding to the second annular slide rail 43 are circumferentially formed at the edge of the top surface of the lower grinding disc 3, and a plurality of second ball placement grooves 32 corresponding to the first annular slide rail 42 are circumferentially formed in the middle of the top surface of the lower grinding disc 3. Sand sheets 33 are arranged in both the first ball placement grooves 31 and the second ball placement grooves 32;

[0024] Through the settings of the disc 41, the first annular slide rail 42, the second annular slide rail 43, the first ball placement groove 31 and the second ball placement groove 32, when it is necessary to perform rounding treatment on a batch of steel balls, the batch of steel balls are respectively placed inside the first ball placement groove 31 and the second ball placement groove 32. After the upper grinding disc 4 and the lower grinding disc 3 are closed to each other, the steel balls inside the first ball placement groove 31 and the second ball placement groove 32 are respectively in contact with the inner walls of the second annular slide rail 43 and the first annular slide rail 42. When the upper grinding disc 4 rotates, the steel balls move randomly in the first ball placement groove 31 and the second ball placement groove 32 under the action of the second annular slide rail 43 and the first annular slide rail 42 and continuously rub against the abrasive sheet 33. It can not only realize the simultaneous processing of multiple steel balls but also realize the all-round grinding of the burrs on the surface of the steel balls, thereby effectively improving the working efficiency of the equipment.

[0025] Further, referring to Figure 1 As shown, it is worth noting that a power assembly for driving the rotation and lifting of the upper grinding disc 4 is provided above the upper grinding disc 4;

[0026] The power assembly includes two lifting cylinders 7 symmetrically installed on the inner wall of the top end of the chassis 1, a lifting plate 6 fixedly connected to the telescopic ends of the two lifting cylinders 7, and a driving motor 5 installed on the bottom surface of the lifting plate 6. The output shaft of the driving motor 5 is fixedly connected to the center position of the top surface of the upper grinding disc 4;

[0027] Through the setting of the power assembly, when it is necessary to perform rounding treatment on the steel balls, the lifting cylinders 7 are started. The lifting cylinders 7 act on the lifting plate 6, the driving motor 5 and the upper grinding disc 4 to move downward towards the lower grinding disc 3. After the upper grinding disc 4 and the lower grinding disc 3 are closed, the driving motor 5 is turned on. The driving motor 5 drives the disc 41 in the middle of the upper grinding disc 4 to rotate and acts on the first annular slide rail 42 and the second annular slide rail 43 to rotate, so as to perform grinding treatment on the steel balls placed in the first ball placement groove 31 and the second ball placement groove 32, making the steel balls smooth.

[0028] Further, referring to Figure 1 、 Figure 4 and Figure 5 As shown, it is worth noting that an electromagnetic plate 8 is telescopically arranged between the upper grinding disc 4 and the lower grinding disc 3. An adsorption groove matching the first ball placement groove 31 and the second ball placement groove 32 is opened at the bottom of the electromagnetic plate 8. A driving assembly for acting on the telescopic movement of the electromagnetic plate 8 is arranged on one inner wall of the chassis 1;

[0029] The driving assembly includes two fixing seats 9 symmetrically fixed on one inner wall of the chassis 1, a bidirectional lead screw 10 rotatably arranged between the two fixing seats 9, two sliders 12 symmetrically and slidably arranged on the bidirectional lead screw 10, and two connecting rods 13 distributed in a V shape between the electromagnetic plate 8 and the two sliders 12. One ends of the two connecting rods 13 are respectively hinged to one ends of the two sliders 12 in a one-to-one correspondence, and the other ends of the two connecting rods 13 are both hinged to one side wall of the electromagnetic plate 8. The bidirectional lead screw 10 rotates through one of the fixing seats 9 and is fixedly connected with a runner 14, and a handle 15 is fixedly connected to the edge position of the runner 14;

[0030] A guide rod 11 is further arranged between the two fixing seats 9. The guide rod 11 is located on one side of the bidirectional lead screw 10, and both of the two sliders 12 are slidably connected with the guide rod 11;

[0031] Through the arrangement of the electromagnetic plate 8, the driving assembly and the guide rod 11, after the rounding process of the steel balls is completed, manually rotate the handle 15. The handle 15 acts on the runner 14 and the bidirectional lead screw 10 to rotate, causing the sliders 12 to move away from each other on the bidirectional lead screw 10 and the guide rod 11. As a result, the connecting rods 13 extend and act on the electromagnetic plate 8 to extend above the lower grinding disc 3. Then, energize the electromagnetic plate 8. The electromagnetic plate 8 generates magnetism to adsorb the steel balls in the grinding grooves 9 into the adsorption grooves. Then, rotate the handle 15 in the reverse direction. The handle 15 acts on the runner 14 and the bidirectional lead screw 10 to rotate in the reverse direction, causing the sliders 12 to move closer to each other on the bidirectional lead screw 10 and the guide rod 11. As a result, the connecting rods 13 contract and act on the electromagnetic plate 8 to retract from above the lower grinding disc 3, realizing the rapid batch picking of steel balls, avoiding manual picking of steel balls, and improving production efficiency. When the two sliders 12 slide on the bidirectional lead screw 10, the guide rod 11 can limit the movement trajectory of the sliders 12, preventing the sliders 12 from shifting and thus affecting the telescoping of the electromagnetic plate 8.

[0032] Further, as shown in Figure 1 It is worth noting that a collection box 16 is arranged on one side of the carrier 2, and the collection box 16 is located directly below the electromagnetic plate 8.

[0033] Through the arrangement of the collection box 16, when the electromagnetic plate 8 retracts, turn off the power supply of the electromagnetic plate 8. The electromagnetic plate 8 loses magnetism, and the steel balls fall off from the adsorption grooves and fall into the collection box 16 to achieve centralized collection of the processed steel balls, facilitating subsequent transportation and processing, and further improving production efficiency.
