[0025] The following further elaborates on the present utility model in conjunction with embodiments:

[0026] As Figures 1-5As shown in the figure, the utility model provides a cold rolling machine for bearing rings, which includes a box body 1. A support plate 2 is fixedly installed in the middle of the interior of the box body 1. A partition plate 3 is fixedly installed at the front end of the interior of the box body 1. A number of leakage holes 4 are formed on the surface of the partition plate 3. A chute 5 is formed in the middle of the upper end of the support plate 2. A rolling wheel 6 is movably installed at the front end of the support plate 2. A support column 7 is installed below the rolling wheel 6. A fixing mechanism 8 is installed outside the support column 7. A cooling mechanism 9 is installed at the left end of the box body 1. A shunt pipe 10 is fixedly installed at the top end of the interior of the box body 1. Nozzles 11 are symmetrically and fixedly installed on both sides of the lower end of the shunt pipe 10. An electric push rod 12 is fixedly installed at the top end of the rear side of the interior of the box body 1. A support plate 13 is fixedly installed at the output end of the electric push rod 12. A first motor 14 is fixedly installed on the inner side of the support plate 13. A second motor 15 is fixedly installed at the lower side of the rear end of the support plate 2. A box door 16 is movably hinged to the front of the box body 1. An observation window 17 is fixedly installed on the surface of the box door 16. The processing condition of the bearing ring can be viewed through the observation window 17.

[0027] The output rod of the first motor 14 is fixedly connected to the middle of the rear end of the rolling wheel 6. The output rod of the first motor 14 is slidably connected to the inside of the chute 5. The output end of the second motor 15 is drivingly connected to the rear end of the support column 7. The nozzles 11 are inclined and aligned with the rolling wheel 6.

[0028] Through the fixing mechanism 8, the arc-shaped fastening plate 83 can be attached to the inner wall of the bearing ring, and the hydraulic cylinder 82 can push the fastening plate 83 to move, so that the fastening plate 83 can support and fix the ring, thus meeting the cold rolling treatment of bearing rings of different sizes and improving the applicability of the device. Through the cooling mechanism 9, the coolant can be transported into the shunt pipe 10 through the delivery pipe 97 and sprayed onto the rolling wheel 6 through the nozzles 11, so as to cool down the rolling wheel 6. At the same time, the used coolant can be filtered and recycled, thereby reducing the use cost.

[0029] As Figure 4 shown, the fixing mechanism 8 includes a fixing seat 81. The lower end of the fixing seat 81 is fixedly connected to the outside of the support column 7 at equal intervals. A hydraulic cylinder 82 is fixedly installed in the middle of the upper end of the fixing seat 81. A fastening plate 83 is fixedly installed at the output end of the hydraulic cylinder 82. Telescopic rods 84 are symmetrically and fixedly installed on both the front and rear sides of the upper end of the fixing seat 81. A spring 85 is sleeved outside the telescopic rod 84.

[0030] The fastening plate 83 is arc-shaped, and a rubber anti-slip pad is fixedly installed on the outside of the fastening plate 83.

[0031] One end of the spring 85 is fixedly connected to the upper end surface of the fixing seat 81, and the other end is fixedly connected to the inner side of the fastening plate 83.

[0032] When moving through the fastening plate 83, the telescopic rod 84 and the spring 85 will be stretched. Under the action of the self-elasticity of the set spring 85, the fastening plate 83 can be supported, thereby improving the fixing effect of the fastening plate 83 on the bearing race. By setting the rubber anti-slip pad, the fixing effect on the race can be further improved, and at the same time, clamping damage to the inner wall of the race can be avoided.

[0033] As Figure 5 shown, the cooling mechanism 9 includes a liquid storage cavity 91. The liquid storage cavity 91 is opened below the partition plate 3. A filter plate 92 is movably installed inside the liquid storage cavity 91. A plurality of magnetic rods 93 are fixedly installed at equal intervals on the surface of the filter plate 92. A handle 94 is fixedly installed in the middle of the front end of the filter plate 92. An installation plate 95 is fixedly installed at the lower left end of the box body 1. A liquid pump 96 is fixedly installed on the upper end of the installation plate 95. A delivery pipe 97 is fixedly installed on the upper end of the liquid pump 96 and is connected and communicated.

[0034] The liquid storage cavity 91 is communicated with the leakage holes 4.

[0035] The right end of the liquid pump 96 is communicated with the inside of the liquid storage cavity 91. The top of the delivery pipe 97 extends into the box body 1. The top of the delivery pipe 97 is fixedly connected and communicated with the middle of the upper end of the shunt pipe 10.

[0036] The cooled coolant will fall on the partition plate 3 and flow back into the liquid storage cavity 91 through the leakage holes 4. The coolant will pass through the filter plate 92 and the magnetic rods 93. The set filter plate 92 can filter the coolant, and the set magnetic rods 93 can magnetically adsorb the residual processing debris in the coolant, thereby achieving the purpose of collecting and cleaning the waste chips. Finally, the filter plate 92 can be pulled out through the handle 94 to facilitate the cleaning of the filter plate 92 and the magnetic rods 93.

[0037] Next, the working principle of the bearing race cold rolling machine will be specifically described.

[0038] As Figures 1-5As shown, when the bearing ring cold rolling machine is in use, first, the bearing ring can be sleeved on the support column 7. Then, multiple hydraulic cylinders 82 can be started. The hydraulic cylinders 82 push the fastening plate 83 to move outward, so that the fastening plate 83 fits against the inner wall of the bearing sleeve, and then the bearing ring can be supported and fixed, so that it will not fall off during cold rolling. Then, close the box door 16, and start the first motor 14 and the second motor 15 respectively. The first motor 14 can drive the rolling wheel 6 to rotate, and the second motor 15 can drive the support column 7 to rotate, so that the support column 7 drives the bearing sleeve to be cold rolled to rotate. Then, start the hydraulic cylinder 82. The hydraulic cylinder 82 can drive the rotating rolling wheel 6 downward, so that the rolling wheel 6 contacts the bearing ring. Then, the cold rolling process of the bearing ring can be realized by using the rotating rolling wheel 6. When it is necessary to cool the rolling wheel 6, the liquid pump 96 can be started, so that the liquid pump 96 can pump out the coolant in the liquid storage cavity 91, and transport it to the shunt pipe 10 through the delivery pipe 97, and then spray all the coolant onto the rolling wheel 6 through the inclined nozzle 11, so as to cool the rolling wheel 6.

[0039] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
