Internal welding rib removal device for high frequency welded pipe

Abstract

The invention relates to high-frequency welding pipe machining equipment, in particular to a device matched with high-frequency welding equipment for removing welding ribs in a high-frequency welding pipe blank. The device comprises a base; and a support plate is arranged on the base. A fixed block is arranged on one side of the support plate, and is provided with a chute; a lead screw is arranged in the chute; and two ends of the lead screw respectively extend out from the top and the bottom of the fixed block. The lead screw above the fixed block is in threaded connection with a nut. A rack is arranged on one side of the chute; the lead screw corresponding to the rack is provided with a gear; and the gear is engaged with the rack. A cutter rod is arranged at the lower end of the lead screw; a cutter bit is at one end, far from the lead screw, of the cutter rod; and an edge is arranged at the top of the cutter bit. A pit is formed in the bottom of the cutter bit; a slide block is arranged in the pit; the bottom of the slide block downwards extends out from a notch of the pit; and a roller is arranged thereon. A spring is arranged between the top of the slide block and the bottom of the pit. The inner welding rib removing device can improve the quality of finished high-frequency welding pipes, is higher in working efficiency and automation degree, and has no need to additionally occupy places.

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 removing devices used in the industry are all traditional welding rod removing devices. It mainly includes a base, on which there is a support plate in a vertical arrangement, a knife holder is fixed on one side of the support plate, the knife surface of the scraper is perpen...

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
