Description

A fully automated V-process casting process for wear-resistant steel balls Technical Field

[0001] This invention relates to the field of steel ball processing technology, specifically to a fully automated V-process casting process for wear-resistant steel balls. Background Technology

[0002] Steel balls are classified according to their manufacturing process into ground steel balls, forged steel balls, and cast steel balls. They are also classified according to the materials used, such as bearing steel balls, regular steel balls, and alloy steel balls. Bearing steel balls are essential basic components in industry. Alloy steel balls are spherical iron alloy wear-resistant bodies made primarily of carbon, chromium, manganese, and molybdenum, produced through forging, rolling, and casting. They are a crucial component in modern crushing industries, mining, and cement production. A riser is a supplementary part added to the top or side of a casting to prevent defects. Functionally, in the mold, the riser cavity is a storage cavity that supplies metal during casting formation, serving to prevent venting, release air, and collect slag. The primary function of a riser is feeding. Different risers have different forms, sizes, and locations.

[0003] Existing large-diameter steel ball casting equipment results in a large amount of molding sand adhering to the surface of the ball during casting and unloading. This sand is difficult to clean after complete cooling, and the large size of the steel balls makes processing inconvenient. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a fully automated V-process casting process for wear-resistant steel balls, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides a fully automated V-process casting process for wear-resistant steel balls, comprising the following steps:

[0006] Step 1: Casting. Casting is carried out through the casting box of the casting equipment. After casting, the steel balls are transported to the polishing box.

[0007] Step 2: The first polishing is performed. The conveyor belt transports the steel balls, and at this time, the surface of the steel balls comes into contact with the abrasive conveyor belt. The abrasive conveyor belt polishes the contact surface of the steel balls. The push plate at the lower right is driven by the cylinder to push the lower right of the steel balls, pushing the steel balls to rotate forward and to the left at the same time. While the steel balls are being polished by the top abrasive conveyor belt, multiple sides of the steel balls can be polished. The push plate at the upper left is driven by the cylinder to push the upper left of the steel balls, pushing the steel balls to rotate forward and to the right at the same time. While the steel balls are being polished by the top abrasive conveyor belt, multiple sides of the steel balls can be polished, so that the surface of the steel balls can be evenly contacted with the abrasive conveyor belt when they are being transported by the conveyor belt.

[0008] Step 3: The steel balls are transported to the guide channel. After being diverted by the guide channel, they are individually transported into the polishing box. The guide channel has a built-in lifting barrier device to limit the movement of the steel balls, so that the steel balls are transported into the polishing box one by one.

[0009] Step 4: Perform a second polishing. The steel ball falls between the movable friction wheel and the fixed friction wheel. The lifting frame moves downward, causing the friction ring and the adsorption ring to come into contact with the surface of the steel ball. The friction ring and the adsorption ring reciprocate under the drive of the rotating shaft. While the surface of the steel ball is polished a second time by the friction ring, the adsorption ring adsorbs the debris. At this time, the movable friction wheel and the fixed friction wheel rotate, causing the steel ball to rotate and adjust the position of the surface in contact with the friction ring. This can effectively polish the steel ball a second time, and multiple steel balls can be polished at the same time. After the surface polishing is completed and cleaned, the molding sand and burrs on the surface of the steel ball can be effectively removed. Then, it is output through the guide channel. The adsorption ring is connected to the external negative pressure mechanism through the adsorption pipe, which can effectively adsorb the debris.

[0010] Step 5, Output: After polishing, the cylinder drives the rotating frame to rotate, causing the movable friction wheel to rotate downwards. At this time, the steel ball loses its limit and slides down for discharge. Then, the cylinder drives the rotating frame to rotate, causing the movable friction wheel to reset and process the next steel ball again.

[0011] As a further aspect of the present invention: during the casting process in step one, casting is carried out through a casting box, and after casting is completed, the steel balls are transported to a polishing box.

[0012] As a further aspect of the present invention: during the first polishing in step two, the conveyor belt transports the steel ball, at which time the surface of the steel ball contacts the abrasive conveyor belt, and the abrasive conveyor belt polishes the contact surface of the steel ball. The push plate at the lower right is driven by the cylinder to push the lower right of the steel ball, pushing the steel ball to rotate forward and to the left at the same time. While the steel ball is being polished by the top abrasive conveyor belt, multiple sides of the steel ball can be polished. The push plate at the upper left is driven by the cylinder to push the upper left of the steel ball, pushing the steel ball to rotate forward and to the right at the same time. While the steel ball is being polished by the top abrasive conveyor belt, multiple sides of the steel ball can be polished, so that the surface of the steel ball can be evenly contacted with the abrasive conveyor belt when it is being driven by the conveyor belt.

[0013] As a further aspect of the present invention: during the first polishing in step two, one of the two push plates is located to the lower right of the steel ball, and the other is located to the upper left of the steel ball.

[0014] As a further aspect of the present invention: during the second polishing in step four, the steel ball falls between the movable friction wheel and the fixed friction wheel. The lifting frame moves downward, causing the friction ring and the adsorption ring to abut against the surface of the steel ball. The friction ring and the adsorption ring reciprocate under the drive of the rotating shaft. While the surface of the steel ball is being polished a second time by the friction ring, the debris is adsorbed away by the adsorption ring. At this time, the movable friction wheel and the fixed friction wheel rotate, causing the steel ball to rotate and adjust the position of the surface in contact with the friction ring. This can effectively polish the steel ball a second time, and multiple steel balls can be polished at the same time. After the surface polishing is completed and cleaned, the molding sand and burrs on the surface of the steel ball can be effectively removed. Then, the ball is output through the guide channel. The adsorption ring is connected to the external negative pressure mechanism through the adsorption pipe, which can effectively adsorb the debris.

[0015] As a further aspect of the present invention: during the output of step five, after polishing is completed, the cylinder drives the rotating frame to rotate, which in turn drives the movable friction wheel to rotate downward. At this time, the steel ball loses its limit and slides down for discharge. Then, the cylinder drives the rotating frame to rotate, which in turn drives the movable friction wheel to reset and reprocess the next steel ball.

[0016] The casting equipment includes a casting box and a polishing box located on one side of the casting box. The top of the polishing box is equipped with a sanding conveyor belt for grinding the surface of the steel balls during transport, and the bottom of the polishing box is equipped with a conveyor belt for transporting the steel balls. A rotating rod driven by a cylinder is rotatably connected to the inner cavity of the polishing box. Push plates are fixedly connected to the surface of the rotating rod. There are two rotating rods; one push plate is located to the lower right of the steel ball, and the other to the upper left. During operation, the cylinder drives the rotating rod to rotate, which in turn drives the two push plates to rotate. One push plate pushes the lower right of the steel ball, causing it to rotate forward and simultaneously to the left. While the steel ball is being ground by the top sanding conveyor belt, it can also... To polish multiple sides of the steel ball, another pusher plate pushes the steel ball from the upper left, causing it to rotate forward and to the right simultaneously. This multi-angle rotation ensures that the surface of the steel ball makes uniform contact with the abrasive conveyor belt as it passes through, effectively polishing all areas of the surface during transport. One side of the polishing box is connected to a wiping box via a guide channel. The guide channel has multiple holes for conveying single steel balls only. A fixed frame is fixedly connected to the inner cavity of the wiping box. A fixed friction wheel driven by a motor is rotatably connected to the surface of the fixed frame. A rotating frame driven by a cylinder is rotatably connected to one side of the fixed frame. A movable friction wheel driven by a motor is rotatably connected to the inner cavity of the rotating frame. The distance between the fixed friction wheel and the movable friction wheel is two-thirds of the steel ball's diameter, effectively holding the steel ball between them. The inner cavity of the wiping box is slidably connected to a lifting frame driven by a cylinder. The inner cavity of the lifting frame is rotatably connected to a rotating shaft driven by a motor. Friction rings and adsorption rings are fixedly connected to the surface of the rotating shaft. Both the friction rings and adsorption rings are semi-circular rings adapted to the surface of the steel ball. After the steel ball falls between the movable and fixed friction wheels, the lifting frame moves downwards, causing the friction rings and adsorption rings to abut against the surface of the steel ball. Driven by the rotating shaft, the friction rings and adsorption rings reciprocate, performing a secondary polishing of the steel ball's surface through the friction rings. The adsorption ring adsorbs the debris. At this time, the movable and fixed friction wheels rotate, causing the steel ball to rotate and adjust the position of the surface in contact with the friction ring. This effectively performs secondary polishing on the steel ball, and multiple steel balls can be polished simultaneously. After the surface polishing is completed and cleaned, the molding sand and burrs on the surface of the steel ball can be effectively removed. Then, it is output through the guide channel. The adsorption ring is connected to the external negative pressure mechanism through the adsorption pipe, which can effectively adsorb the debris. After polishing is completed, the cylinder drives the rotating frame to rotate, causing the movable friction wheel to rotate downward. At this time, the steel ball loses its limit and slides down for discharge. Then, the cylinder drives the rotating frame to rotate, causing the movable friction wheel to reset and process the next steel ball.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. In this invention, the surface of the steel ball being polished is able to make uniform contact with the abrasive conveyor belt when it is driven by the conveyor belt. The rotation of the movable friction wheel and the fixed friction wheel drives the steel ball to rotate and adjust the surface position in contact with the friction ring. This can effectively polish the steel ball a second time and effectively remove burrs and molding sand from the surface of the steel ball, resulting in higher quality finished products.

[0019] 2. The present invention makes material positioning very convenient. During the first polishing, the steel balls are conveyed by a conveyor belt. During the second polishing, the movable friction wheel and the fixed friction wheel can effectively output the steel balls while positioning them, and their positions can be adjusted.

[0026] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0027] Please refer to Figures 1-5. This invention provides a technical solution: a fully automated V-process casting process for wear-resistant steel balls, comprising the following steps:

[0028] Step 1: Casting. Casting is carried out through the casting box 1 of the casting equipment. After casting, the steel balls are transported to the polishing box 3.

[0029] Step 2: The first polishing is performed. Conveyor belt 2 transports the steel ball, and at this time, the surface of the steel ball contacts the abrasive conveyor belt 4. The abrasive conveyor belt 4 polishes the contact surface of the steel ball. The push plate 6 at the lower right is driven by the cylinder to push the lower right of the steel ball, pushing the steel ball to rotate forward and to the left at the same time. While the steel ball is being polished by the top abrasive conveyor belt 4, multiple sides of the steel ball can be polished. The push plate 6 at the upper left is driven by the cylinder to push the upper left of the steel ball, pushing the steel ball to rotate forward and to the right at the same time. While the steel ball is being polished by the top abrasive conveyor belt 4, multiple sides of the steel ball can be polished, so that the surface of the steel ball can be evenly contacted with the abrasive conveyor belt 4 when it is being driven by conveyor belt 2.

[0030] Step 3: The steel balls are transported to the guide channel 7. After being diverted by the guide channel 7, they are transported individually into the polishing box 3. The guide channel 7 is equipped with a lifting barrier device to limit the movement of the steel balls, so that the steel balls are transported individually into the polishing box 3.

[0031] Step 4: Perform a second polishing. The steel ball falls between the movable friction wheel 17 and the fixed friction wheel 15. The lifting frame 9 moves downward, causing the friction ring 11 and the adsorption ring 12 to come into contact with the surface of the steel ball. The friction ring 11 and the adsorption ring 12 reciprocate under the drive of the rotating shaft 10. While the surface of the steel ball is polished a second time by the friction ring 11, the debris is adsorbed by the adsorption ring 12. At this time, the movable friction wheel 17 and the fixed friction wheel 15 rotate, causing the steel ball to rotate and adjust the position of the surface in contact with the friction ring 11. This can effectively polish the steel ball a second time, and multiple steel balls can be polished at the same time. After the surface polishing is completed and cleaned, the molding sand and burrs on the surface of the steel ball can be effectively removed. Then, the ball is output through the guide channel 7. The adsorption ring 12 is connected to the external negative pressure mechanism through the adsorption pipe 13, which can effectively adsorb the debris.

[0032] Step 5, Output: After polishing, the cylinder drives the rotating frame 16 to rotate, which in turn drives the movable friction wheel 17 to rotate downward. At this time, the steel ball loses its limit and slides down for discharge. Then, the cylinder drives the rotating frame 16 to rotate, which in turn drives the movable friction wheel 17 to reset and process the next steel ball again.

[0033] In step one, casting is carried out through casting box 1. After casting is completed, the steel balls are transported to polishing box 3.

[0034] In step two, during the first polishing, conveyor belt 2 transports the steel ball, and the surface of the steel ball contacts the abrasive conveyor belt 4. The abrasive conveyor belt 4 polishes the contact surface of the steel ball. The push plate 6 at the lower right, driven by the cylinder, pushes the lower right side of the steel ball, causing it to rotate forward and to the left. While the steel ball is being polished by the top abrasive conveyor belt 4, multiple sides of the steel ball can be polished. The push plate 6 at the upper left, driven by the cylinder, pushes the upper left side of the steel ball, causing it to rotate forward and to the right. While the steel ball is being polished by the top abrasive conveyor belt 4, multiple sides of the steel ball can be polished, ensuring that the surface of the steel ball can contact the abrasive conveyor belt 4 evenly when it is being driven by conveyor belt 2.

[0035] During the first polishing in step two, one of the two push plates 6 is located to the lower right of the steel ball, and the other is located to the upper left of the steel ball.

[0036] In step four, during the second polishing, the steel ball falls between the movable friction wheel 17 and the fixed friction wheel 15. The lifting frame 9 moves downward, causing the friction ring 11 and the adsorption ring 12 to come into contact with the surface of the steel ball. The friction ring 11 and the adsorption ring 12 reciprocate under the drive of the rotating shaft 10. While the surface of the steel ball is polished a second time by the friction ring 11, the debris is adsorbed by the adsorption ring 12. At this time, the movable friction wheel 17 and the fixed friction wheel 15 rotate, causing the steel ball to rotate and adjust the position of the surface in contact with the friction ring 11. This can effectively polish the steel ball a second time, and multiple steel balls can be polished at the same time. After the surface polishing is completed and cleaned, the molding sand and burrs on the surface of the steel ball can be effectively removed. Then, the ball is output through the guide channel 7. The adsorption ring 12 is connected to the external negative pressure mechanism through the adsorption pipe 13, which can effectively adsorb the debris.

[0037] In step five, after polishing is completed, the cylinder drives the rotating frame 16 to rotate, which in turn drives the movable friction wheel 17 to rotate downward. At this time, the steel ball loses its limit and slides down for discharge. Then, the cylinder drives the rotating frame 16 to rotate, which drives the movable friction wheel 17 to reset and process the next steel ball again.

[0038] The casting equipment includes a casting box 1 and a polishing box 3 located on one side of the casting box 1. The top of the polishing box 3 is equipped with a sanding conveyor belt 4 for grinding the surface of the steel balls during transport, and the bottom of the polishing box 3 is equipped with a conveyor belt 2 for transporting the steel balls. A rotating rod 5 driven by a cylinder is rotatably connected to the inner cavity of the polishing box 3. Push plates 6 are fixedly connected to the surface of the rotating rod 5. There are two rotating rods 5, one with a push plate 6 located to the lower right of the steel ball and the other to the upper left. During use, the cylinder drives the rotating rod 5 to rotate, which in turn drives the two push plates 6 to rotate. One pushes the lower right of the steel ball, causing it to rotate forward and to the left simultaneously. While the steel ball is being ground by the sanding conveyor belt 4, multiple surfaces of the steel ball can be polished. The surface is polished, and another pusher plate 6 pushes the steel ball from the upper left, causing the steel ball to rotate forward and to the right at the same time. This multi-angle rotation ensures that the surface of the steel ball can evenly contact the abrasive conveyor belt 4 as it is conveyed by the conveyor belt 2, effectively polishing all parts of the surface during transport. One side of the polishing box 3 is connected to the wiping box 8 via a guide channel 7. The guide channel 7 has multiple holes for conveying a single steel ball at a time. A fixed frame 14 is fixedly connected to the inner cavity of the wiping box 8. A fixed friction wheel 15 driven by a motor is rotatably connected to the surface of the fixed frame 14. A rotating frame 16 driven by a cylinder is rotatably connected to one side of the fixed frame 14. A movable friction wheel 17 driven by a motor is rotatably connected to the inner cavity of the rotating frame 16. The distance between the wiping wheel 15 and the movable friction wheel 17 is two-thirds of the diameter of the steel ball, which can effectively hold the steel ball between the movable friction wheel 17 and the fixed friction wheel 15. The inner cavity of the wiping box 8 is slidably connected to a lifting frame 9 driven by a cylinder. The inner cavity of the lifting frame 9 is rotatably connected to a rotating shaft 10 driven by a motor. Friction rings 11 and adsorption rings 12 are fixedly connected to the surface of the rotating shaft 10. Both friction rings 11 and adsorption rings 12 are semi-circular rings adapted to the surface of the steel ball. After the steel ball falls between the movable friction wheel 17 and the fixed friction wheel 15, the lifting frame 9 moves downward to make the friction rings 11 and adsorption rings 12 abut against the surface of the steel ball. The friction rings 11 and adsorption rings 12 reciprocate under the drive of the rotating shaft 10. While the surface of the steel ball undergoes secondary polishing, debris is adsorbed and removed by the adsorption ring 12. At this time, the movable friction wheel 17 and the fixed friction wheel 15 rotate, causing the steel ball to rotate and adjust its contact position with the friction ring 11. This effectively performs secondary polishing on the steel ball, and multiple steel balls can be polished simultaneously. After surface polishing and cleaning, the molding sand and burrs on the surface of the steel ball are effectively removed. The ball is then output through the guide channel 7. The adsorption ring 12 is connected to an external negative pressure mechanism through the adsorption pipe 13, effectively adsorbing debris. After polishing, the cylinder drives the rotating frame 16 to rotate, causing the movable friction wheel 17 to rotate downwards. At this time, the steel ball loses its limit and slides down for discharge. Then, the cylinder drives the rotating frame 16 to rotate again.This resets the movable friction wheel 17, allowing it to re-process the next steel ball.
