Description

Technical Field

[0001] The utility model belongs to the technical field of welding ring grinding, in particular to a welding ring grinding device for a ductile iron pipe spigot. Background Art

[0002] There are different types of large-diameter ductile iron pipes. Among them, the self-anchored ductile iron pipe needs to be welded with an annular weld mark, i.e., the welding ring, at its socket. During the welding process, due to the splashing of welding slag, a large amount of welding slag will exist around the welding ring. In the production of ductile iron pipes, there are strict requirements on the size of the welding ring. Therefore, it is necessary to grind the welding slag around or adjacent to the welding ring to make the processing size of the welding ring meet the production requirements;

[0003] The way to grind the welding slag is to use a manual handheld grinder. During long-term grinding, the grinding wheel will be damaged and the grinding effect will be greatly reduced. At this time, the grinding wheel needs to be replaced. The grinding wheel is usually installed with fixing bolts. Auxiliary tools are required during replacement and disassembly. The fixing bolts must be removed before replacement. It takes a long time. For this reason, we provide a ductile iron pipe socket weld ring grinding device. Utility Model Content
