[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, a ring rolling device of a hole reaming machine includes a mounting side plate 1, a ring rolling structure 2 is fixedly installed in the middle of the top of the front end of the mounting side plate 1, forming structures 3 are fixedly installed on the left and right sides of the top of the front end of the mounting side plate 1, a scraping structure 4 is fixedly installed at the right position of the middle of the front end of the mounting side plate 1, a collecting structure 5 is fixedly installed at the bottom of the front end of the mounting side plate 1, a placing structure 6 is provided at the left position of the bottom of the mounting side plate 1, and a cooling structure 7 is fixedly installed at the left position of the rear end of the mounting side plate 1. The mounting side plate 1 can provide an installation position for some parts of the device, the rolling ring structure 2 can roll the casting, the forming structure 3 can extrude and limit the casting during the rolling process, so that the casting will eventually be in a circular ring shape after rolling, the scraping structure 4 can continuously scrape off the oxide debris on the surface of the casting when it is rotated during processing, so as to improve product quality, the collecting structure 5 can collect the fallen oxide debris, which is convenient for the staff to transport them uniformly and quickly, the placing structure 6 can provide a placement position for multiple castings after the processing is completed, which is convenient for the staff to transport them uniformly, and the cooling structure 7 sprays water mist on the surface of the casting to cool it uniformly.

[0026] like Figure 1 and Figure 2As shown, a pressurizing port is provided at the top of the mounting side plate 1, a hydraulic column 21 is fixedly installed at the top of the inner wall of the pressurizing port, a mounting block 22 is fixedly installed at the bottom end of the hydraulic column 21, a pressure wheel 23 is rotatably installed at the front end of the mounting block 22, a driving motor 24 is fixedly installed at the middle position of the rear end of the mounting side plate 1, and a driving wheel 25 is fixedly installed at the output end of the driving motor 24 through the mounting side plate 1, and the driving wheel 25 is located at the bottom position of the pressure wheel 23. When the staff places the casting on the driving wheel 25, the hydraulic column 21 can drive the pressure wheel 23 to move downward through the mounting block 22, and when the bottom of the pressure wheel 23 fits the top of the casting, the driving motor 24 can drive the driving wheel 25 to rotate, so that the casting is deformed by the joint rolling of the pressure wheel 23 and the driving wheel 25 during rotation.

[0027] like Figure 1 and Figure 2 As shown, the forming structure 3 includes a mounting seat 31, the rear end of each mounting seat 31 is fixedly connected to the left and right positions of the top of the front end of the mounting side plate 1, a hydraulic rod 32 is rotatably installed on the inner side of the mounting seat 31, an L-shaped clamping arm 33 is fixedly installed on the output end of the hydraulic rod 32, and the middle part of each L-shaped clamping arm 33 is rotatably connected to the left and right positions of the middle part of the front end of the mounting side plate 1, and a limiting wheel 34 is rotatably installed at the bottom of the L-shaped clamping arm 33. The mounting seat 31 can provide a mounting position for some parts. When the casting is rolled, the hydraulic rod 32 can drive the L-shaped clamping arm 33 to rotate until the outer wall of the limiting wheel 34 is attached to the outer wall of the casting and pressure is applied thereto, so that the casting can be limited during the rolling deformation process so that it finally becomes a circular ring.

[0028] like Figure 1 and Figure 3 As shown, the scraping structure 4 includes a second mounting block 41, a mounting cylinder 42 is fixedly mounted on the left side of the second mounting block 41, a spring 43 is fixedly mounted on the bottom of the inner wall of the mounting cylinder 42, a scraping rod 44 is slidably mounted on the inner wall of the mounting cylinder 42, and the bottom of the scraping rod 44 is fixedly connected to the top of the spring 43. The second mounting block 41 can provide a mounting position for some parts. When the diameter of the casting increases with the rolling of the casting and fits with the top of the scraping rod 44, the scraping rod 44 can scrape the oxide debris generated on its outer wall. In the process of increasing the diameter of the casting, the scraping rod 44 is displaced in the mounting cylinder 42 by the contact pressure generated by the casting. The spring 43 can provide a reverse support force for the scraping rod 44 during its displacement, so that the top of the scraping rod 44 always fits with the outer wall of the casting.

The collection cart 53 can collect the fallen oxide debris. After the collection is completed, the staff can take the push-pull rod 56 out of the placement slot 57. The coupling 55 can make the push-pull rod 56 rotate at multiple angles, which is convenient for the staff to drag and pull the collection cart 53 through the push-pull rod 56. When the staff needs to fix the collection cart 53, the two guide wheels 52 can limit the collection cart 53 when it is pushed into the inner position of the two limit slots 51. Multiple guide wheels 52 can reduce the friction force of the limit bar 54 on the inner wall of the limit slot 51 when the collection cart 53 is displaced, so that the staff can quickly take out or place the collection cart 53 from the limit slot 51, and then rotate the push-pull rod 56 again to clamp it on the inner side of the placement slot 57 to limit and fix the collection cart 53.

[0030] like Figure 5 As shown, the placement structure 6 includes a trolley 61, a placement rack 62 is fixedly installed on the top of the trolley 61, and a locking assembly 63 is fixedly installed at the rear end of the bottom of the trolley 61 and the left position of the rear end of the bottom of the mounting side plate 1.

The water tank 71 can store cooling water, and the water pump 72 can pump water out of the water tank 71 and spray it out from the atomizing nozzle 74 through the water supply pipe 73, so as to cool the casting placed on the placement rack 62, and the staff can add cooling water to the water tank 71 through the water supply pipe.

[0032] The working principle of the utility model is as follows: when the staff places the casting on the driving wheel 25, the rolling ring structure 2 can roll the casting, the forming structure 3 can extrude and limit the casting during the rolling process, so that the casting will finally be in a circular ring shape after rolling, the scraping structure 4 can continuously scrape off the oxide debris on the surface of the casting when it is rotated during processing, so as to improve the product quality, the collecting structure 5 can collect the fallen oxide debris, which is convenient for the staff to transport them uniformly and quickly, the placing structure 6 can provide a placement position for multiple castings after the processing is completed, which is convenient for the staff to transport them uniformly, and the cooling structure 7 sprays water mist on the surface of the casting to cool it uniformly.
