A device for removing internal welding ribs for high-frequency welded pipes

Abstract

The invention relates to a high-frequency welding pipe machining device, in particular to an inner welding rib removing device for a high-frequency welding pipe. The inner welding rib removing device comprises a base, and a supporting plate is arranged on the base. A fixing block is arranged on one side of the supporting plate. A sliding groove is formed in the fixing block. A screw rod is arranged in the sliding groove. The two ends of the screw rod extend out of the top and the bottom of the fixing block correspondingly. A nut is arranged at the section, located above the fixing block, of the screw rod. A rack is arranged on one side of the sliding groove, a gear is arranged at the section, corresponding to the rack, of the screw rod, and the gear is engaged with the rack. The lower end of the screw rod is connected with a cutter bar. The end, away from the screw rod, of the cutter bar is provided with a cutter head. A cutting edge is arranged at the top of the cutter head, and the cutting edge is perpendicular to the axis of the cutter bar. A pit is formed in the bottom of the cutter head and is internally provided with a sliding block. An air hole is formed in the position, above the sliding block, of the pit wall of the pit. The air hole is connected with an air pipe which is provided with a valve. A wheel is arranged at the bottom of the sliding block. By the adoption of the inner welding rib removing device, the quality of a finished high-frequency welding pipe can be improved, the working efficiency and the automation degree are high, and an extra site does not need to be occupied.

Description

technical field [0001] The invention relates to high-frequency welded pipe processing equipment, in particular to a device used in conjunction with high-frequency welded equipment for removing welding ribs in high-frequency welded pipe blanks. Background technique [0002] It is known in the machinery industry that during the production process of high-frequency welded pipes, the raw materials need to be crimped to form a tube blank. This tube blank has a gap running through its longitudinal direction, and the gap is filled and eliminated by high-frequency welding equipment. , the welded tube blank needs to go through the welding rod removal device to remove the welding rod. At present, the welding rod removal device used in the industry includes a base, a support plate arranged vertically on the base, a knife rest is fixed on one side of the support plate, and a scraper is arranged on one side of the knife rest. The support plate is vertical, the lower end of the scraper p...

AI Technical Summary

Problems solved by technology

This kind of welding rib removal device can only remove the outer welding ribs, so most of the finished high-frequency welded pipes have inner welding ribs, and the quality is poor

In the prior art, after the outer welding ribs are removed from the tube blank, manual scraping is also used to remove the inner welding ribs, but the work efficiency and automation of manual operations are low, and additional space is required
