Description

Technical Field

[0001] This utility model relates to the technical field of steel ball production equipment, and specifically discloses a steel ball material feeding device. Background Technology

[0002] A steel ball is a spherical part made of metallic steel, typically carbon steel, stainless steel, alloy steel, or tool steel, and manufactured through processes such as forging, rolling, and grinding. Its core functions include supporting rotating mechanical parts, transmitting power, reducing friction, providing wear and pressure resistance, and serving as a grinding medium for crushing or mixing materials. In the machinery manufacturing industry, steel balls, through their precise roundness, hardness, and surface finish, ensure the smooth operation of equipment. They are also used in flow control valves, instruments, and sealing components in high-temperature and high-pressure environments, and their performance directly affects the operating efficiency and safety performance of mechanical equipment.

[0003] In the production of steel balls, heat preservation measures are required during high-temperature stages such as smelting, forging, and heat treatment. The main purpose is to maintain temperature stability, reduce heat loss, avoid fluctuations in material properties, and lower energy consumption and production costs. However, in current steel ball production processes, most feeding devices rely on natural temperature conveying. During the conveying process, damage detection of the steel balls is required, and subsequent manual reheating is necessary. These damage detection and heating processes are extremely time-consuming, occupying a large portion of the steel ball feeding time and keeping steel ball production efficiency consistently low, significantly hindering overall production efficiency. Utility Model Content

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] This specific embodiment provides a steel ball material feeding device, such as... Figures 1-8 As shown, the system includes a platform 1. Multiple adjusting rods 34 are symmetrically installed on the bottom of the platform 1. There are four adjusting rods 34 located at the four corners of the bottom of the platform 1. Each adjusting rod 34 has a base plate 35 fixedly installed at its bottom end. The base plates 35 are made of rubber, thus providing shock absorption for the platform 1. A support frame 3 is fastened to the platform 1. The support frame 3 is positioned above the platform 1 and is fastened to the outside of the platform 1 via a combination of square plates and bolts.

[0030] A first roller 11 and a second roller 12 are rotatably mounted at both ends of the frame 1. The second roller 12 is located at the feed end of the frame 1, and the first roller 11 is located at the discharge end of the frame 1. A conveyor belt 2 is fitted around the outer periphery of the first roller 11 and the second roller 12. The conveyor belt 2 may be made of high-temperature resistant rubber. A first gear 13 is fixedly mounted on the outer side of the first roller 11. A servo motor 14 is fixedly mounted on the inner bottom of the frame 1. The servo motor 14 is fixedly mounted with a motor mount that is fastened to the side of the frame 1. The output shaft of the servo motor 14 is arranged parallel to the first roller 11, and a second gear 15 is fixedly mounted on its end. The second gear 15 and the first gear 13 are connected by a chain 16, causing the servo motor 14 to drive the first roller 11 to rotate, thereby causing the conveyor belt 2 to rotate and transport within the frame 1.

[0031] Multiple rubber rings 17 are fixedly installed on the surface of the conveyor belt 2 at equal intervals. Each rubber ring 17 has an inner groove with its opening facing upward. The inner groove wall of the rubber ring 17 is in contact with the outer wall of the steel ball, which facilitates the storage of the steel ball and allows the steel ball to flow stably on the conveyor belt 2.

[0032] The support frame 3 is internally fixedly equipped with a first clamping block 18 and a third clamping block 21, which are symmetrically arranged. A first hanging rod 19 is fastened inside the first clamping block 18. The first hanging rod 19 is vertically arranged and its top end is fastened to the first clamping block 18. A second clamping block 20 is fastened to the outer periphery of the bottom end of the first hanging rod 19. A flaw detection probe 4 is fixedly connected to the outer side of the second clamping block 20. The information extraction end of the flaw detection probe 4 faces the conveyor belt 2 and can perform flaw detection on the steel balls on the conveyor belt 2. The third clamping block 21 is arranged at the front end of the first clamping block 18. The second lifting rod 22 is fastened inside the third clamping block 21. The second lifting rod 22 is arranged vertically and its top end is fastened to the third clamping block 21. The bottom end of the second lifting rod 22 is fastened to the outer periphery of the fourth clamping block 23. The bottom of the fourth clamping block 23 is fixed with a connecting piece 24. The bottom of the connecting piece 24 is fastened to a ring plate 25. The ring plate 25 is arranged coaxially with the flaw detection probe 4, so that the ring plate 25 is arranged directly below the flaw detection probe 4, thereby facilitating the data acquisition of the flaw detection probe 4 and reducing the interference of the external environment.

[0033] An electric rail 5 is fixedly installed inside the support frame 3, and the electric rail 5 is arranged at the rear end of the flaw detection probe 4. The electric rail 5 is arranged perpendicular to the conveyor belt 2 and above the conveyor belt 2. The length of the electric rail 5 is greater than the width of the conveyor belt 2. A support plate 6 is slidably installed on the electric rail 5, and the support plate 6 can slide linearly along the electric rail 5. An electromagnet 7 is fixedly installed at the bottom of the support plate 6. When the electromagnet 7 is energized, it becomes magnetic, thereby attracting the steel ball in the rubber ring 17. A retention box 26 is fastened to the outside of the stand 1. The retention box 26 is arranged below the electromagnet 7. The top of the retention box 26 has an open structure, which facilitates the electromagnet 7 to send the steel ball into the retention box 26.

[0034] A material box 8 is placed on the outer side of the discharge end of the platform 1, and the top of the material box 8 is positioned lower than the platform 1. Multiple hydraulic cylinders 27 are fixedly installed inside the material box 8. There are four hydraulic cylinders 27 evenly distributed within the inner cavity of the material box 8, and the bottom end of each hydraulic cylinder 27 is tightly connected to the inner cavity of the material box 8. The cylinder bodies of each hydraulic cylinder 27 are connected via hydraulic lines 28, and a solenoid valve 29 is installed on the hydraulic lines 28. The solenoid valve 29 can effectively control the hydraulic cylinders 27 through the hydraulic lines 28. The hydraulic rods within each hydraulic cylinder 27 are all vertically upwards, and the top end of each hydraulic rod is tightly connected to a material plate 9. The side wall of the material plate 9 slides against the inner wall of the material box 8, thereby allowing the material plate 9 to move vertically up and down within the inner cavity of the material box 8.

[0035] The top of the material box 8 is provided with a box cover 32. A rotating shaft 33 is rotatably installed on the middle part of both sides of the box cover 32. The rotating shaft 33 is rotated and cooperates with the material box 8. The steel ball can make the box cover 32 flip, so that the steel ball is arranged on the material plate 9.

[0036] The material box 8 has a ventilation window 30 on its side wall, and the electric hot air blower 10 is fixedly installed on the outside of the ventilation window 30 so that the electric hot air blower 10 continuously delivers constant temperature hot air to the inner cavity of the material box 8; the material plate 9 has a plurality of ventilation holes 31, the inner diameter of which is smaller than the outer diameter of the steel ball, so that the upper space of the material plate 9 is connected to the lower space.

[0037] The working principle of this utility model is as follows:

[0038] Operators can place steel balls inside rubber rings 17. By starting servo motor 14, the conveyor belt 2 can rotate within the frame 1, thus transporting the steel balls from the feed end to the discharge end of the frame 1. When the steel ball moves to below the flaw detection probe 4, the servo motor 14 stops, and the flaw detection probe 4 can perform flaw detection on the steel ball. If the flaw detection fails to meet the production standard, the electromagnet 7 is energized and magnetically attracts the steel ball, sending the steel ball that failed the flaw detection into the storage box 26. If the steel ball meets the production standard, the steel ball can enter the material box 8 from the discharge end of the frame 1 and be pressed down onto the material plate 9 under the action of gravity. At this time, the electric hot air blower 10 inputs hot air into the inner cavity of the material box 8, thereby keeping the steel ball warm, saving the production time required for secondary heating, and speeding up the steel ball feeding rate.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
