Description

Technical Field

[0001] The utility model relates to the technical field of loose flange processing, in particular to a grinding device for a loose flange. Background Art

[0002] Loose flange, also called slip-on flange, refers to a flange that is loosely fitted on the flange of a container or pipe. Flanges are parts that connect shafts to each other and are used to connect pipe ends; they are also used as flanges on equipment inlets and outlets, used to connect two devices. Loose flanges are loose flanges. The flange can be made by flanging, direct turning or welding a ring. The advantage is that when the flange is deformed, no additional torque is generated on the container or pipe, and it is easy to manufacture. It can be made of materials different from the container or pipe, which is convenient for saving precious metals. The disadvantage is that the flange is relatively thick. It is suitable for occasions where the container or pipe is lined with brittle materials and the pressure is not high. It is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electricity, aerospace, shipbuilding, etc.

[0003] At present, when the loose flanges on the market are used, the outer wall of the loose flange needs to be polished. In actual use, when the outer wall of the loose flange is polished, grinding equipment is needed to polish the loose flange. When most grinding equipment polishes the loose flange, the loose flange is manually held or fixed in position by a limiting mechanism, and then the loose flange is polished by a grinding roller. However, both methods involve continuous polishing of the outside of the loose flange by the grinding roller, which makes the outside of the loose flange prone to excessive polishing, thereby increasing the defective rate of the loose flange.
