Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a cold rolling machine for bearing rings. Background Art

[0002] Cold rolling is a precision cold forming method that obtains finished parts by extruding ring-shaped rotating parts at room temperature. It is a new process without cutting. Nowadays, the production of bearings is also usually carried out using cold rolling machines.

[0003] When the current cold rolling machine is working, workers need to complete the loading, adjustment of workpieces and unloading after the cold rolling is completed in sequence. The above work (especially the loading process) must be repeated every time the cold rolling is performed. Therefore, the workers will be in a state of fatigue for a long time. Especially in the peak season with more orders, the physical load of the workers far exceeds the range that the human body can normally bear. Therefore, it is not conducive to the health of the employees.

[0004] In summary, there is an urgent need to improve the existing cold rolling machine so that it can better fit the workers' operation and give workers a short break during the production process to ensure the continuity of production. Utility Model Content

[0046] In this embodiment, the clamping structure includes:

[0047] The sliding seat 20 is slidably connected to the machine body 10 and is controlled by the first hydraulic cylinder 21 to move closer to or away from the auxiliary cold rolling wheel 12;

[0048] The hinge frame 22 is integrally formed on the side of the sliding seat 20 close to the auxiliary cold rolling wheel 12;

[0049] The support wheel 23 is hinged to the hinge frame 22;

[0050] When the sliding seat 20 is controlled by the first hydraulic cylinder 21 to approach the auxiliary cold rolling wheel 12 , the supporting wheel 23 can contact the bearing ring 13 .

[0051] In this embodiment, the sliding structure includes:

[0052] The mounting base 30 is slidably connected to the body 10. The body 10 is provided with a sliding opening 31 that passes through the front and back of the body 10. The mounting base 30 is slidably connected to the sliding opening 31;

[0053] The second hydraulic cylinder 32 is mounted on the machine body 10 and is used to control the lifting movement of the mounting base 30;

[0054] The auxiliary cold rolling wheel 12 is mounted on the mounting seat 30 .

[0055] In this embodiment, the storage assembly includes:

[0056] A material storage rack 40 is mounted on the machine body 10 and forms a material storage area;

[0057] Positioning rails 41 are mounted on the storage rack 40 via support rods 41a, and a storage area for bearing rings is formed between the positioning rails 41;

[0058] The bottom of the storage rack 40 is provided with a feeding structure, which can control the movement of the bearing rings in the storage area;

[0065] refer to Figures 1-4 , the principle of this embodiment is:

[0066] During operation, workers can put multiple bearing rings into the storage rack at one time. The bearing rings on the storage rack are controlled by the feeding structure to move toward the auxiliary cold rolling wheel for loading;

[0067] To be more specific, when in use, the auxiliary cold rolling wheel is controlled to descend and correspond to the storage area of ​​the storage rack. At the same time, the conveyor roller of the feeding structure is started, and the pusher block is controlled to move in a cycle through the conveyor belt. The circulating pusher block can control the bearing ring to move toward the auxiliary cold rolling wheel. During this process, the third hydraulic cylinder controls the auxiliary cold rolling wheel to move close to the storage rack to complete the material receiving work until the bearing ring moves onto the auxiliary cold rolling wheel to complete the loading.

[0068] After loading is completed, the second hydraulic cylinder drives the auxiliary cold rolling wheel to rise and makes the bearing ring contact with the main cold rolling wheel. Then, the first hydraulic cylinder drives the sliding seat close to the auxiliary cold rolling roller and makes the supporting wheel contact with the bearing ring, thereby supporting another position of the bearing ring. Then, by starting the main cold rolling wheel, the cold rolling process of the bearing ring is completed. After the processing is completed, the supporting wheel is moved away from the auxiliary cold rolling wheel, and the bearing ring is removed. Then the above process is repeated to complete the continuous cold rolling process.

[0069] In summary, in this embodiment, workers can pre-load multiple bearing rings into the storage rack at one time, and rely on the cold rolling machine of this embodiment to complete continuous cold rolling processing. During this process, workers mainly supervise the work and appropriately adjust the position of the bearing rings, thus eliminating frequent physical labor, so they can take appropriate rest and ensure the health of the workers.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
