Description

Technical Field

[0001] The invention relates to the technical field of bearing ring forging, in particular to a bearing ring forging processing system. Background Art

[0002] The bearing includes a ring, a rolling element, and a cage. Most of the bearing rings are made of high-carbon chromium bearing steels such as GCr15, G8Cr15, GCr15SiMn, GCr15SiMo, GCr18Mo, and 100Cr6. In the existing forging process of the bearing rings, the surface of the bearing rings is rough due to the low processing accuracy of the ordinary ring rolling machine, and the decarburized layer of the bearing rings is thickened due to the impure gas atmosphere in the annealing furnace, which increases the subsequent cutting allowance and causes steel waste;

[0003] The utility model with announcement number CN209969481U specifically discloses a bearing ring forging processing system, which relates to the technical field of bearing ring forging processing. It includes a heating furnace, a punching machine, a CNC ring rolling machine, an air cooler, and a double-layer roller bottom nitrogen protection annealing furnace. The heating furnace is used to heat the material segment of high carbon chromium bearing steel. The punching machine is used to roughen, extrude, and punch the heated material segment in sequence to obtain the axially punched material segment. The CNC ring rolling machine is used to roll the axially punched material segment to obtain the ring. The air cooler is used to air cool the ring. The double-layer roller bottom nitrogen protection annealing furnace is used to spheroidize anneal the air-cooled ring. This application can reduce the surface roughness of the bearing ring and eliminate the decarburization layer after spheroidizing annealing, thereby reducing the cutting allowance, saving steel, and improving the utilization rate of raw materials.

[0004] In the bearing ring forging processing system, cooling of the bearing ring is a key link in the process steps. The air cooling device in the prior art has a poor cooling effect on the bearing ring and a long cooling time, which cannot meet the high-efficiency production requirements. In the prior art, the bearing ring is cooled by spraying cooling water on the bearing ring in a high-temperature state. However, in actual use, the cooling water will vaporize when it encounters the bearing ring in a high-temperature state. The vaporized high-temperature steam rises and contacts with the cooling water nozzle for a long time, which will cause scale to adhere to the surface of the nozzle, and the nozzle will be easily blocked if used for a long time.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 , the present invention provides a technical solution:

[0030] A bearing ring forging processing system comprises a cooling box 1, wherein movable notches 11 are formed through both sides of the cooling box 1, a conveying mechanism 2 is arranged inside the cooling box 1, and both ends of the conveying mechanism 2 extend to the outside of the cooling box 1 through the movable notches 11;

[0031] An air cooling assembly 3 is provided inside the cooling box 1 at the upper side of the conveying mechanism 2, and grille air inlet holes 5 are provided on the front and rear sides of the cooling box 1 at the lower side of the conveying mechanism 2. The grille air inlet holes 5 are formed by several equally distributed hollow heat dissipating fins fixed on the cooling box 1.

[0032] The conveying mechanism 2 includes ear plates 22 symmetrically fixed at the movable slot 11, and a conveying roller 24 is rotatably connected between the two ear plates 22. A conveying belt 23 is sleeved on the outside of the conveying roller 24, and the conveying belt 23 is made of mesh alloy metal. A driving motor 21 is fixed on the outside of the ear plate 22, and the output shaft of the driving motor 21 is connected to one end of the conveying roller 24.

[0033] Specifically, the air cooling component 3 includes a dual-axis motor 31, and the upper output shaft of the dual-axis motor 31 is sleeved and fixed with a sleeve 33, and the outside of the sleeve 33 is equidistantly annularly fixed with fan blades 34, the upper end surface of the cooling box 1 is provided with a mounting groove 13, the fan blades 34 are located in the mounting groove 13, and a protective net 14 is fixed inside the mounting groove 13 at the upper side of the fan blades 34, the outside of the dual-axis motor 31 is fixed with a mounting plate 32, and the other end of the mounting plate 32 is fixed to the inner wall of the cooling box 1, the lower output shaft of the dual-axis motor 31 is rotatably connected with a condensation plate 35, and an electromagnet is embedded between the condensation plate 35 and the lower output shaft of the dual-axis motor 31, and the electromagnet is fixed to the condensation plate 35, the lower output shaft of the dual-axis motor 31 is made of magnetic metal material, a vortex tube 4 is provided on the lower side of the condensation plate 35, and injection holes are equidistantly provided on the lower end surface of the vortex tube 4.

[0034] By adopting the above technical solution, when working, add a proper amount of coolant to the water storage chamber at the bottom of the cooling box 1, and then use a tool to place the bearing ring to be cooled on the surface of the conveyor belt 23 at the right end of the cooling box 1, and then control the drive motor 21 and the dual-axis motor 31 to run. The drive motor 21 drives the conveyor belt 23 to move to the left by driving the conveyor roller 24, and then carries the bearing ring to be cooled through the inside of the cooling box 1. At this time, the dual-axis motor 31 rotates to suck the air on the lower side, and the external air enters the cooling box 1 through the grille air inlet 5, and blows the bearing ring transported on the surface of the conveyor belt 23 through the mesh conveyor belt 23 to achieve air cooling.

[0035] Specifically, a cleaning ring 37 is sleeved on the outside of the vortex tube 4, and a slider 38 is fixed to the upper end of the cleaning ring 37. A slide groove 36 is opened on the lower side of the condensation plate 35 at a position corresponding to the slider 38, and the top of the slider 38 is located inside the slide groove 36 and is slidably connected to the slide groove 36.

[0036] By adopting the above technical solution, when the dual-axis motor 31 controls the operation of the fan blades 34, the electromagnet between the lower output shaft and the condensation plate 35 is powered off, so it will not drive the condensation plate 35 to rotate. When a large amount of impurities or scale adheres to the surface of the vortex tube 4 and needs to be cleaned, the electromagnet is controlled to be conductive, and the dual-axis motor 31 rotates slowly, driving the slider 38 and the cleaning ring 37 to move along the surface of the vortex tube 4, and the slider 38 moves inside the slide groove 36 to clean the impurities on the surface of the vortex tube 4.

[0037] Specifically, the condensation plate 35 is made of heat-conducting metal copper, and a water tank with a vortex structure is opened inside the condensation plate 35. The two ends of the water tank are respectively connected to a water inlet hole and a drainage hole, and the water inlet hole and the drainage hole are connected to an external water supply device.

[0038] By adopting the above technical solution, the design of the condensation plate 35 allows the coolant to contact the steam rising from the high-temperature bearing ring to condense, thereby reducing the consumption of the coolant and further recovering the heat through the internal water tank.

[0039] Specifically, the bottom of the cooling box 1 is a water storage chamber, and a guide platform 12 with an isosceles trapezoidal structure is fixed in the water storage chamber. A suction pipe 51 is fixed on the upper side of the guide platform 12 at a position corresponding to the cooling fins, and the other end of the suction pipe 51 is connected to the inside of the cooling fins. A water pump 6 is fixed on the rear side of the cooling box 1 at a position above the grille air inlet hole 5. The water inlet end and the drainage end of the water pump 6 are respectively fixedly connected with water pipes 61. The water inlet end water pipe 61 is connected to the top of the cooling fin, and the drainage end water pipe 61 is connected to the vortex tube 4.

[0040] By adopting the above technical solution, the water pump 6 on the rear side of the cooling box 1 sucks the coolant in the water storage chamber through the water pipe 61 and transports it to the vortex tube 4, and finally sprays it downward on the surface of the bearing ring passing through the injection hole under the vortex tube 4 to achieve water cooling. The cooled coolant is filtered by the mesh conveyor belt 23 and finally flows back and falls into the water storage chamber.

[0041] Working principle: When working, add a proper amount of coolant to the water storage chamber at the bottom of the cooling box 1, and then use a tool to place the bearing ring to be cooled on the surface of the conveyor belt 23 at the right end of the cooling box 1, and then control the drive motor 21 and the double-axis motor 31 to run. The drive motor 21 drives the conveyor belt 23 to move to the left by driving the conveyor roller 24, and then carries the bearing ring to be cooled through the inside of the cooling box 1. At this time, the double-axis motor 31 rotates to suck the air on the lower side, and the external air enters the cooling box 1 through the grille air inlet 5, and passes through the mesh conveyor belt 2 The bearing ring transported on the surface of the conveyor belt 23 is blown to realize air cooling. During the air cooling, the water pump 6 at the rear side of the cooling box 1 sucks the coolant in the water storage chamber through the water pipe 61 and transports it to the vortex tube 4. Finally, the coolant is sprayed downward on the surface of the bearing ring passing through the lower injection hole of the vortex tube 4 to realize water cooling. The cooled coolant is filtered by the mesh conveyor belt 23 and finally flows back to the water storage chamber. During the falling process of the coolant, it can also be blown by the wind generated by the fan blades 34 driven by the dual-axis motor 31 to realize the cooling of the coolant.

[0042] The purpose of designing the guide platform 12 in the water storage chamber is that although the coolant is filtered by the mesh conveyor belt 23, fine metal dust can still easily fall through the conveyor belt 23. Therefore, the coolant is diverted by the guide platform 12 to precipitate on both sides of the guide platform 12. The user handles the precipitate regularly. The suction pipe 51 on the guide platform 12 is used to absorb water from the water storage chamber.

[0043] When the dual-axis motor 31 is controlling the operation of the fan blades 34, the electromagnet between the lower output shaft and the condensation plate 35 is powered off, so the condensation plate 35 will not be driven to rotate. When a large amount of impurities or scale adheres to the surface of the vortex tube 4 and needs to be cleaned, the electromagnet is controlled to be conductive, and the dual-axis motor 31 rotates slowly, driving the slider 38 and the cleaning ring 37 to move along the surface of the vortex tube 4. The slider 38 moves inside the slide groove 36 to clean the impurities on the surface of the vortex tube 4.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
