[0002] In modern industry, steel balls are a fundamental and critical component, widely used in many fields such as machinery manufacturing, automotive industry, and aerospace. Their surface strength plays a decisive role in the reliability and service life of equipment.

[0003] However, traditional methods for improving the surface strength of steel balls have many drawbacks. Common heat treatment methods, such as quenching and tempering, can improve surface hardness to some extent, but they easily lead to deformation of the steel balls, and the increase in hardness is limited, making it difficult to cope with complex working conditions. Surface treatment technologies such as chemical plating and electroplating can improve surface properties, but the adhesion between the coating and the substrate is sometimes not ideal, and peeling is prone to occur during long-term use. In addition, these traditional technologies are often cumbersome, have low production efficiency, and some processes involve a large amount of chemical reagents, causing significant environmental pollution. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel ball performance enhancement device, which solves the technical problems of limited performance enhancement, cumbersome operation, and low production efficiency of existing technologies, thereby achieving the goal of improving the surface performance of steel balls.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a steel ball performance improvement device, including a placement platform installed in a processing box, wherein the processing box is provided with a shot peening strengthening mechanism and a laser strengthening mechanism for improving the surface performance of the steel ball.

[0006] The shot peening strengthening mechanism includes a shot storage tank installed on the top of the processing box, and a shot peening pump connected to the shot storage tank is installed on the top of the processing box. A shot peening pipe extending into the processing box is installed at the bottom interface of the shot peening pump.

[0009] A further improvement is that a support plate is installed below the filter plate, and a dust collection box is slidably installed between the support plate and the filter plate.

[0010] A further improvement is that the steel ball rotating assembly includes an arc-shaped tray installed in the middle of the placement platform, and a rubber turntable is installed in a rotating groove opened in the placement platform, with the top of the rubber turntable extending into the arc-shaped tray. A rotating shaft connected to the side of the rubber turntable is rotatably connected in a rotating hole opened in the placement platform, and a drive motor for driving the rotating shaft to rotate is installed in a motor compartment opened in the placement platform.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Given the limited effectiveness of existing technologies in improving steel ball performance, their cumbersome operation, and low production efficiency, this embodiment provides a steel ball performance improvement device. Please refer to... Figures 1-5This embodiment provides a steel ball performance enhancement device that can improve the surface properties of steel balls. The device includes a placement platform 2 installed inside a processing chamber 1. The processing chamber 1 is equipped with a shot peening strengthening mechanism 3 and a laser strengthening mechanism 4 for enhancing the surface properties of the steel balls. The shot peening strengthening mechanism 3 sprays a high-speed stream of shot to impact the surface of the steel ball, causing plastic deformation and forming a strengthening layer, thereby increasing the surface hardness of the steel ball. The laser strengthening mechanism 4 uses a high-energy-density laser beam to irradiate the surface of the steel ball, causing plastic deformation and changes in the microstructure, thereby improving the surface hardness, strength, and fatigue resistance of the steel ball.

[0031] Since existing technologies have limited effectiveness in improving the performance of steel balls and are cumbersome to operate with low production efficiency, this device is equipped with a shot peening strengthening mechanism 3. The shot peening strengthening mechanism 3 includes a shot storage tank 31 installed on the top of the processing box 1, and a shot peening pump 32 connected to the shot storage tank 31 is installed on the top of the processing box 1. A shot peening pipe 33 extending into the processing box 1 is installed at the bottom interface of the shot peening pump 32. A shot peening recovery assembly 34 is installed inside the processing box 1, and a steel ball rotating assembly 35 for rotating the steel ball is installed on the placement platform 2. When the shot peening pump 32 is started, the steel shot in the shot storage tank 31 is drawn into the shot peening pipe 33 and impacts the surface of the steel ball from the top, causing plastic deformation of the steel ball surface and forming a strengthening layer, thereby improving the surface hardness, residual compressive stress and fatigue resistance of the steel ball.

[0032] During the shot peening process, the shot peening will knock off some impurities from the surface of the steel ball and stick to its surface. Therefore, the device is also equipped with a shot peening recovery component 34. The shot peening recovery component 34 includes a material discharge hole 341 opened on the left side of the placement platform 2, and a filter plate 342 installed below the placement platform 2. A recovery pipe 343 is installed in the return port opened on the side of the processing box 1, and the top of the recovery pipe 343 is connected to the shot storage tank 31. A suction pump 344 is installed on the recovery pipe 343.

[0033] The placement platform 2 has a slope that is lower on the left and higher on the right. The filter plate 342 is installed inside the processing box 1 with the left side higher than the right side. The return port is located at the lowest end of the filter plate 342. The sprayed steel shot rolls down the slope into the discharge hole 341 and falls onto the filter plate 342. As the inclined filter plate 342 rolls, the impurities on its surface are shaken off. Then, the suction pump 344 pumps the steel shot back into the shot storage tank 31 through the recovery pipe 343, realizing the recycling of steel shot.

[0034] A support plate 345 is installed below the filter plate 342, and a dust collection box 346 is slidably installed between the support plate 345 and the filter plate 342. Impurities falling during the rolling of steel shot fall into the dust collection box 346. The dust collection box 346 can be removed periodically to remove the dust.

[0035] Since the steel shot ejected from the shot peening pipe 33 can only impact-strengthen the top of the steel ball, the device is also equipped with a steel ball rotating assembly 35. The steel ball rotating assembly 35 includes an arc-shaped tray 351 installed in the middle of the placement table 2, and a rubber turntable 352 installed in a rotating groove opened in the placement table 2. The top of the rubber turntable 352 extends into the arc-shaped tray 351. A rotating shaft 353 connected to the side of the rubber turntable 352 is rotatably connected in a rotating hole opened in the placement table 2. A drive motor 354 for driving the rotating shaft 353 to rotate is installed in a motor compartment opened in the placement table 2. During the shot peening process, the drive motor 354 is started to drive the rotating shaft 353 to rotate, which in turn drives the rubber turntable 352 to rotate. Thus, the steel ball in the arc-shaped tray 351 is slowly rotated by the rubber turntable 352, thereby achieving comprehensive impact strengthening of the steel ball surface.

[0036] Example 2

[0037] Based on Example 1, such as Figures 1-5 As shown, to further improve the surface performance of the steel ball, the device is also equipped with a laser strengthening mechanism 4. The laser strengthening mechanism 4 includes a pulsed laser generator 41 installed on the top of the processing box 1, and a cable 42 extending into the processing box 1 is installed at the interface of the pulsed laser generator 41. A laser emitter 43 inclined towards the steel ball is installed at the bottom of the cable 42. After or before shot peening, the pulsed laser generator 41 is activated, and a high-energy-density laser beam is emitted to the surface of the steel ball through the laser emitter 43 to irradiate the surface of the steel ball. The surface material absorbs the laser energy instantly to generate high-temperature and high-pressure plasma. The plasma expands rapidly to generate a powerful shock wave, which acts on the surface of the steel ball, causing plastic deformation and changes in the microstructure, thereby improving the surface hardness, strength and fatigue resistance of the steel ball.
