Description

Technical Field

[0001] The utility model relates to a ring cutting device used for steel pipe submerged arc welding, belonging to the technical field of cutting equipment. Background Art

[0002] Submerged arc welded steel pipe: It is made of strip steel coil as raw material, extruded at room temperature, and welded by automatic double-wire double-sided submerged arc welding process. During the submerged arc welding of the steel pipe, cutting equipment can be used to perform circular cutting or grooving operations on its outer wall.

[0003] A spiral submerged arc welded steel pipe cutting device with Chinese patent number CN218657270U relates to the technical field of steel pipe cutting. The spiral submerged arc welded steel pipe cutting device comprises a spiral submerged arc welded steel pipe, on the surface of which a fixing ring and a circular ring are movably sleeved. The spiral submerged arc welded steel pipe cutting device enables a cutting head to rotate around the spiral submerged arc welded steel pipe, thereby enabling the cutting head to cut the spiral submerged arc welded steel pipe, thereby facilitating guiding when the cutting head cuts the spiral submerged arc welded steel pipe, thereby ensuring the smoothness of the cutting of the spiral submerged arc welded steel pipe, improving the neatness of the cutting surface, and facilitating precise welding in the later stage.

[0004] While the cutting blade in the cutting knife cover is moving in a circular motion, the steel pipe body is cut along the circular motion path. During the cutting process, the debris generated by the steel pipe body will adhere to the cutting blade and be difficult to clean. Manual cleaning is not only time-consuming and laborious, but also easy to scratch the hands of the staff, which has low safety.

[0005] Therefore, a ring cutting device for steel pipe submerged arc welding is proposed. Utility Model Content

[0012] Further preferably, the maintenance oil passes through the one-way solenoid valve pipeline and flows out of the oil storage cavity, and the maintenance oil contacts the outer side wall of the cutting blade.

[0013] Further preferably, the cutting base is equipped with a built-in controller, and the controller is interconnected through a wire and a one-way solenoid valve pipeline, a circular electric guide shaft and a cutting blade.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] 1. After the cutting blade has finished cutting, the electromagnetic inner block is powered off to restore the spring to its elastic state. After the convex magnetic inner block is separated from the electromagnetic inner block, the spring can drive the fitting vertical bar to spring outward, so that the fitting vertical bar contacts the outer wall of the cutting blade.
