Description

Technical Field

[0001] This utility model relates to the field of slag scraping technology for ring rolling mills, specifically a slag scraping device for ring rolling mills. Background Technology

[0002] Ring rolling, also known as the rolling forming of ring forgings or hole expansion, is a common forging process for ring parts. Existing ring rolling mills are classified in various ways, including vertical and horizontal types, conventional ring rolling mills, and CNC ring rolling mills. A current ring rolling mill slag scraping device (announcement number: CN214640738U) exhibits at least the following defects during use:

[0003] In the above scheme, the mounting plate is installed on the ring rolling mill, and the cylinder is started. The cylinder drives the scraper plate to move downward and make the bottom of the scraper plate abut against the surface of the workpiece. When the ring rolling mill drives the workpiece to rotate, the scraper plate can scrape the surface of the workpiece. However, in actual use, the above scheme only has one scraper plate, which means that only one side of the ring can be scraped, affecting the scraping efficiency. Therefore, a scraping device for the ring rolling mill is developed. Utility Model Content

In this embodiment, the clamping springs 204 ensure that the scraper blades are in close contact with the two sides of the ring body, thus scraping away the oxide slag on the surface of the ring body.

[0025] An extension frame is fixedly connected to each end of the lifting processing plate 104 on the side facing away from the supporting base plate 201. A lifting back plate 103 is fixedly connected to one end of the two extension frames. A lifting sleeve 102 is slidably connected to the side of the lifting back plate 103 facing the lifting processing plate 104. A lifting cylinder 101 is fixedly connected to the top of the extension frame. The output end of the lifting cylinder 101 is fixedly connected to the top of the lifting sleeve 102. A processing motor 105 is fixedly connected to the inner wall of the lifting sleeve 102.
