Description

Technical Field

[0001] This utility model relates to the field of bearing steel ball production technology, and in particular to a rust prevention treatment device for bearing steel ball production. Background Technology

[0002] Rust prevention treatment devices for bearing steel balls are specialized equipment used to form a protective film on the surface of bearing steel balls after machining by applying rust-preventive oil or other media, thereby preventing oxidation and corrosion. As the core rolling element of a bearing, the quality of the bearing steel ball directly determines the bearing's service life and operational accuracy. After processing through multiple complex processes such as wire drawing, cold heading, and hard grinding, steel balls are prone to surface debris residue, and their material is easily exposed to air and moisture, leading to oxidation and corrosion. With the development of the machinery manufacturing industry and the expanding application scenarios of bearings, the market demand for steel balls is increasing year by year, and the requirements for their rust prevention quality are also rising accordingly. Rust prevention treatment has become an indispensable key link in steel ball production, providing a core demand basis for the research and development and iteration of rust prevention treatment devices. Therefore, a rust prevention treatment device for bearing steel ball production is needed.

[0003] In existing technologies, most rust-preventive oil coatings are applied by immersion or spraying. In immersion devices, when steel balls are piled up, the bottom steel balls are squeezed by the pressure of the upper layer, making it difficult for the surface to fully contact the rust-preventive oil, which easily forms "indentation-type missed coating". In spray devices, if the nozzle angle is fixed, spray dead corners are easy to appear between the steel balls, and the missed coating rate can reach 5% to 8%. Moreover, immersion and spraying can cause localized over-coating or oil dripping on the bearing steel balls. Summary of the Invention

[0004] The purpose of this utility model is to provide a rust prevention treatment device for the production of bearing steel balls, in order to solve the problems mentioned in the background art. In the existing technology, most of the rust prevention oil coatings are immersion or spraying. In the immersion device, when the steel balls are piled up, the bottom steel balls are squeezed by the pressure of the upper layer, and the surface is difficult to fully contact the rust prevention oil, which easily forms "indentation-type missed coating". In the spraying device, if the nozzle angle is fixed, spray dead corners are easy to appear between the steel balls, and the missed coating rate can reach 5% to 8%. Moreover, immersion and spraying can cause localized excessive coating or oil dripping on the bearing steel balls.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rust-prevention treatment device for the production of bearing steel balls, comprising a housing, a fixing foot fixedly connected to the lower surface of the housing, an oil reservoir fixedly connected to the outer surface of the housing, and a connection port provided inside the housing, and further comprising: An oil pump is provided with a connecting pipe on the outer surface of the oil tank, and the oil pump is connected to the outer surface of the connecting pipe. Both the input and output ends of the oil pump are provided with connecting pipes. The outer shell has a motor mounted on its upper surface, the output end of which is fixedly connected to a connecting rod. A rotating cover plate is fixedly connected to the lower end of the connecting rod. The upper surface of the rotating cover plate has a perforated groove, and the upper surface of the rotating cover plate has a wrapping layer.

[0006] Preferably, a conveying pipe is provided on the lower surface of the connection port, and an angled brush is provided on the lower surface of the rotating cover plate.

[0007] Preferably, six sets of the beveled brushes are provided on the rotating cover plate, and a bottom plate is fixedly connected inside the outer shell.

[0008] Preferably, the inner surface of the lower base plate is tapered, and an oil delivery pipe is provided inside the lower base plate, wherein the oil delivery pipe and the connecting pipe are connected in series.

[0009] Preferably, the output end of the oil delivery pipe is connected to a connector, and an outer shell is provided on the outside of the connector, which is fixedly connected to the bottom plate.

[0010] Preferably, the outer surface of the outer shell is provided with oil seepage holes, the inner surface of the lower base plate is provided with several sets of beveled plates, the lower base plate is provided with lower drain holes around its perimeter, and the lower drain holes are provided with shrink plates inside.

[0011] Preferably, the outer shell has a discharge plate inside, a heating roller is provided on the inner side of the discharge plate, and a discharge port is opened on one side surface of the discharge plate, and the discharge port is connected to the outer shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This application, through the design of a casing, fixed feet, oil tank, connecting pipe, oil pump, connecting port, motor, delivery pipe, connecting rod, rotating cover plate, perforated groove, coating layer, and angled brush, allows the oil pump to draw rust-preventive oil from the oil tank and deliver it into the device. Then, the motor drives the connecting rod to rotate the rotating cover plate, and the bearing steel balls fall into the device through the perforated groove. This changes the rust-preventive coating method from spraying or immersion, altering the way the bearing steel balls come into contact with the rust-preventive oil and eliminating the possibility of dripping.

[0013] 2. This application, through the setting of a bottom plate, conveying oil pipe, connecting parts, outer shell, oil seepage hole, angled plate, lower drain hole, shrink plate, discharge plate, heating roller and discharge port, allows rust-preventive oil to enter the conveying oil pipe through the connecting pipe. The rust-preventive oil will overflow from the conveying oil pipe and penetrate through the oil seepage hole on the outer shell, so that the surface of the bottom plate comes into contact with the rust-preventive oil. The rotation of the angled brush will slow down the falling speed of the bearing steel balls. In conjunction with the design of the angled plate, the rust-preventive oil seeping out of the oil seepage hole is also applied to the bearing steel balls, so that the bearing steel balls can better contact the rust-preventive oil and the coating of the bearing steel balls is more uniform.

[0016] 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.

[0017] Please see Figures 1 to 6 This utility model provides a technical solution: it includes a shell 1, a fixing foot 2 fixedly connected to the lower surface of the shell 1, an oil tank 3 fixedly connected to the outer surface of the shell 1, a connection port 6 provided inside the shell 1, a connecting pipe 4 provided on the outer surface of the oil tank 3, an oil pump 5 connected to the outer surface of the connecting pipe 4, and connecting pipes 4 provided at both the input and output ends of the oil pump 5. A motor 7 is provided on the upper surface of the shell 1, a connecting rod 9 is fixedly connected to the output end of the motor 7, a rotating cover plate 10 is fixedly connected to the lower end surface of the connecting rod 9, a hollow groove 11 is opened on the upper surface of the rotating cover plate 10, and a wrapping layer 12 is provided on the upper surface of the rotating cover plate 10. The oil pump 5 draws out the rust-preventive oil from the oil tank 3 and delivers it through the connecting pipe 4. When the motor 7 is started, it will drive the connecting rod 9 to rotate.

[0018] A conveying pipe 8 is provided on the lower surface of the connection port 6, and an angled brush 13 is provided on the lower surface of the rotating cover plate 10. Six sets of angled brushes 13 are provided on the rotating cover plate 10. A lower base plate 14 is fixedly connected inside the outer shell 1. The function of the conveying pipe 8 is to convey the bearing steel balls, and the function of the angled brush 13 is to better apply the anti-rust oil to the bearing steel balls. The inner surface of the lower base plate 14 is conical, and an oil conveying pipe 15 is provided inside the lower base plate 14. The oil conveying pipe 15 and the connecting pipe 4 are connected in series. The conical shape of the lower base plate 14 is to ensure that the bearing steel balls will eventually slide to all sides, thus forming a falling trend. Through the setting of the oil conveying pipe 15 and the connecting pipe 4, the anti-rust oil will be conveyed.

[0019] The output end of the oil delivery pipe 15 is connected to a connector 16. An outer shell 17 is provided on the outside of the connector 16. The outer shell 17 is fixedly connected to the lower base plate 14. An oil seepage hole 18 is provided on the outer surface of the outer shell 17. Several sets of bevel plates 19 are provided on the inner surface of the lower base plate 14. A drain hole 20 is provided around the lower base plate 14. A shrink plate 21 is provided inside the drain hole 20. The rust-preventive oil will overflow from the oil delivery pipe 15, reach the position of the connector 16, and then seep through the oil seepage hole 18 on the outer shell 17. After passing through the protrusion of the bevel plate 19, the bearing steel ball can better contact the rust-preventive oil. Finally, the shrink plate 21 is retracted and drained through the drain hole 20.

[0020] The outer casing 1 has a discharge plate 22 inside, and a heating roller 23 is provided on the inner side of the discharge plate 22. A discharge port 24 is opened on one side surface of the discharge plate 22. The discharge port 24 is connected to the outer casing 1. The bearing steel balls will fall onto the discharge plate 22. The heating roller 23 is provided on the discharge plate 22. The heating roller 23 will heat to 40°, which can better allow the anti-rust oil to adhere to the bearing steel balls.

[0021] Working principle: First, the bearing steel balls are put into the device through the connection port 6. At this time, the motor 7 starts and drives the connecting rod 9 to rotate. The connecting rod 9 will drive the rotating cover plate 10 to rotate. When the bearing steel balls fall, they will slide down through the conveying pipe 8 and come into contact with the coating layer 12 on the rotating cover plate 10. The coating layer 12 will guide the bearing steel balls to fall into the hollow groove 11. In the existing technology, most of the rust-preventive oil coatings are applied by immersion or spraying. In the immersion device, when the steel balls are piled up, the bottom steel balls are squeezed by the pressure of the upper layer, and it is difficult for the surface to be fully in contact with the rust-preventive oil, which easily forms "indentation-type missed coating". If the spraying device has a fixed nozzle angle, spray dead corners are easy to appear in the gaps between the steel balls, and the missed coating rate can reach 5% to 8%. Moreover, immersion and spraying can cause localized over-coating or oil dripping on the bearing steel balls.

[0022] When the bearing balls enter the lower base plate 14 through the perforated groove 11, the oil pump 5 starts, drawing rust-preventive oil from the oil storage tank 3 and sending it through the connecting pipe 4 into the delivery oil pipe 15. The rust-preventive oil overflows from the delivery oil pipe 15, reaching the connector 16, and then permeates through the oil seepage holes 18 on the outer casing 17, allowing the surface of the lower base plate 14 to come into contact with the rust-preventive oil. Because the lower base plate 14 is conical, the bearing balls will spread outwards. At this time, the rotating cover plate 10 is rotating, which will drive the angled brush 13 to rotate, slowing down the falling speed of the bearing balls. At the same time, the rust-preventive oil seeping from the oil seepage holes 18 is applied to the bearing balls. The angled plate 19 set on the lower base plate 14 will slow down the bearing balls. The falling speed of the steel balls, along with the protrusion of the angled plate 19, allows the bearing steel balls to better contact the anti-rust oil, resulting in a more even coating. At this time, the opening and closing of the shrink plate 21 allows the bearing steel balls to fall through the lower drain hole 20. Without special discharge conditions, the rightmost shrink plate 21 will open, allowing the bearing steel balls to fall onto the discharge plate 22. The bearing steel balls will then contact the heating roller 23 on the discharge plate 22 in the outer casing 1. The temperature of the heating roller 23 is around 40°C, which enhances fluidity and allows it to penetrate the gaps and micropores of the steel balls more quickly, avoiding localized missed coatings caused by the viscosity of the oil. The uniformity of the oil film coverage is improved by more than 30%, and the oil is then discharged through the discharge port 24.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
