In the process of casting steel balls, a production method of upper and lower molds is usually adopted. Liquid steel is poured into the cavity of the sand mold through the injection port, and the mold is opened to remove the formed steel ball after the steel cools down.

[0003] In automatic machines used for steel ball production, the control system is the core component. It can automatically adjust the operating parameters of each device according to the production plan and requirements to ensure smooth production and stable product quality. At the same time, the control system can also monitor and record data in real time during the production process, providing important data support for production management.

[0004] Currently, the steel balls produced have poor wear resistance and low strength, and are easily worn during use. For products with high requirements for the surface of steel balls, not only is the surface of the steel ball required to be smooth, but it also needs to have sufficient strength and wear resistance.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example 1

[0021] Please see Figure 1-5An automatic machine and control system for producing wear-resistant steel balls includes an automatic production machine housing 1, a pair of mold liners 6, and multiple wear-resistant balls 11. A fixed mold 2 is fixedly connected inside the automatic production machine housing 1, and a moving mold 3 is located below the fixed mold 2 and inside the automatic production machine housing 1. A pair of hydraulic rods 4 are fixedly connected to the inner wall of the bottom end of the automatic production machine housing 1, and the hydraulic rods 4 are fixedly connected to the moving mold 3. A cooling device 5 is fixedly connected to the inner wall of the upper part of the automatic production machine housing 1. A hemispherical groove is opened between the fixed mold 2 and the moving mold 3. The inner mold liner 6 is fixedly connected to the hemispherical groove. The moving mold 3 moves and forms an injection cavity with the fixed mold 2 by the lifting and lowering of the hydraulic rod 4. The cooling equipment 5 is used to cool the injection-molded steel ball to shorten the production cycle. The inner mold liner 6 includes a hemispherical plate 61, which is fixedly connected to the inner wall of the hemispherical groove. An electromagnetic chuck 62 is fixedly connected to one end of the hemispherical plate 61 near the inner wall of the hemispherical groove. After the electromagnetic chuck 62 is connected to an external power source and is energized and magnetized, it adsorbs and fixes the wear-resistant ball 11 that enters the electromagnetic chuck 62.

[0022] The hemispherical plate 61 is made of a material with high wear resistance, high temperature resistance, and high strength. Tool steel, cemented carbide, and high-performance ceramics can be selected. Tool steel is a type of steel with high hardness and good wear resistance, which is often used to manufacture the inner cavity of molds. High-speed cutting tool steel has high thermal strength and hardness. Cemented carbide, also known as cemented carbide steel or cemented carbide steel, has extremely high hardness and wear resistance, and is suitable for manufacturing molds that require wear resistance. High-performance ceramics are also used in the inner cavity of molds for some special applications because they have excellent hardness and wear resistance, while also having good resistance to high temperature environments.

[0023] A connecting pipe 7 is fixedly connected to the upper end of the fixed mold 2, and the connecting pipe 7 passes through the cooling equipment 5. A raw material box 8 and an auxiliary box 9 are fixedly connected to the upper end of the automatic production machine box 1, and both the raw material box 8 and the auxiliary box 9 are connected to the connecting pipe 7. Multiple wear-resistant balls 11 are arranged in the auxiliary box 9. The multiple wear-resistant balls 11 in the auxiliary box 9 enter the inner mold liner 6 through the connecting pipe 7. The wear-resistant balls 11 include hollow thin iron balls 111. The hollow thin iron balls 111 are arranged in the auxiliary box 9 and are filled with wear-resistant particles 112. After the hollow thin iron balls 111 are melted by the temperature of the molten steel, the wear-resistant particles 112 are exposed and attached to the outer surface of the steel balls, thereby improving the quality and strength of the steel balls.

[0024] Wear-resistant particles 112 are made of one or more of the following materials: tungsten carbide, nickel-phosphorus, zinc, hard chrome, and ceramics. Tungsten carbide is a very hard material with high wear resistance. It is often attached to metal surfaces with other metals to improve wear resistance. Nickel-phosphorus is a common wear-resistant material with good corrosion resistance and wear resistance. Zinc has good corrosion resistance and can improve the wear resistance and durability of the substrate. It is often used for surface treatment of materials such as steel and aluminum alloys. Hard chrome has high hardness and wear resistance and is often used to manufacture parts that need to withstand high loads and friction. Ceramic has high hardness and high temperature resistance and can withstand high wear and friction.

[0025] A control component 10 is fixedly installed at the lower end of the auxiliary box 9. The control component 10 includes a pair of movable slots 101. The pair of movable slots 101 are opened on the inner wall of the lower port of the auxiliary box 9. An iron block 102 is slidably connected in the movable slot 101. An opening and closing baffle 103 is fixedly connected to one end of the pair of iron blocks 102. An electromagnetic block 105 is fixedly connected to the inner wall of the movable slot 101. The iron block 102 is controlled by the magnetic force of the electromagnetic block 105, so that the pair of opening and closing baffles 103 slide in the movable slot 101, thereby achieving the purpose of opening and closing, and thus controlling the release of the wear-resistant ball 11.

[0026] The control component 10 also includes a pair of support springs 104, which are respectively disposed in the movable groove 101. The support springs 104 are made of non-magnetic material. The opening and closing baffle 103 can be kept closed under normal conditions by the elastic force of the support springs 104.

[0027] Both the raw material box 8 and the auxiliary box 9 have a feeding port 12 at the top. Each pair of feeding ports 12 is equipped with a sealing cover. Raw materials or wear-resistant balls 11 can be added through the feeding port 12. The sealing cover can not only reduce the falling of foreign objects, but also prevent the loss of temperature inside the raw material box 8.

[0028] The automatic production machine 1 is also equipped with heat treatment equipment, polishing machine, and quality inspection equipment. By combining multiple devices, the efficiency of automatic steel ball production can be effectively improved. The heat treatment equipment, polishing machine, quality inspection equipment, and cooling equipment 5 all adopt existing technologies.

[0029] A control system for an automatic machine for producing wear-resistant steel balls includes: The feeding module is used to supply raw materials for molten steel; The heat treatment module is used to improve the crystal structure of the steel ball, increase its hardness and strength, and improve its wear resistance; The surface treatment module is used to form a surface layer with high hardness to improve wear resistance; The polishing module is used to polish the steel ball, making its surface smoother, reducing friction with other surfaces, and reducing wear. The coating module is used to form a protective film on the surface of the steel ball to improve its wear resistance; The precision machining module is used to ensure that the size and shape of each steel ball are within the specified range by using precision machining technology, so as to avoid affecting the service life due to uneven wear; The unloading module is used to remove the manufactured steel balls.

[0030] Working principle: First, the hydraulic rod 4 controls the moving mold 3 and the fixed mold 2 to fit tightly together to form an injection cavity. Then, the control component 10 controls the delivery of some wear-resistant balls 11 into the inner mold liner 6. Then, the electromagnetic suction plate 62 is energized and magnetized to attract and fix multiple wear-resistant balls 11 to the wall end of the hemispherical plate 61. Then, molten steel is injected into the raw material box 8 and injected into the inner mold liner 6. When the molten steel comes into contact with the wear-resistant balls 11, the wear-resistant particles 112 are attached to the outer surface of the hollow thin iron balls 111 as they melt. Then, a small amount of wear-resistant balls 11 are delivered from the auxiliary box 9 to cover the upper part of the unwrapped steel balls.

[0031] As can be seen from the above technical solutions, the present invention has the following beneficial effects: This solution involves first placing wear-resistant balls 11 into the inner mold liner 6 and adhering them to its inner wall. Then, molten steel is injected into the inner mold liner 6 through the raw material box 8 to form steel balls. During the injection of molten steel, its high temperature melts the hollow thin iron balls 111, causing wear-resistant particles 112 to adhere to the outer surface of the formed steel balls. This improves the wear resistance of the outer surface of the steel balls, thereby effectively improving the quality and service life of the steel balls.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
