Description
[technical field]
The utility model relates to high-frequency straight seam welded pipe process equipment field, relates in particular to the device that a kind of combination has online inner-burr cleaning of steel pipe and weld seam guide roller.
[technical background]
On the ERW630 high-frequency straight welded pipe production line, because of the steel pipe that requires of production technology is understood the bigger inside and outside burr of generation in the welding production process, according to relevant tube quality standard-required, the inside and outside burr of weld seam all need be removed, so just is provided with the removing equipment of inside and outside burr on the production line behind welding stand.Internally the removing of burr adopts steel duct to add the way of scraping knife bar, in welding, utilizes moving of steel pipe, not have at weld seam and interior burr under the state of cooling directly with interior burr scraping removing.Because the scraping knife bar is in steel duct; the space is narrow and small; and to guarantee to produce continuously could reduce stopping pipe, degradation is managed and the generation of useless pipe, so the backwardness of inner-burr cleaning technology and equipment in the field of business be always enhance productivity, lumber recovery and the bottleneck that reduces cost.Present domestic ERW630 production-line technique equipment all adopts external importing technology, and there is various problems in the internal hair thorn device of first wife's Analysis of Nested Design always, has had influence on the ordinary production of production line.6 aspect problems below concrete the existence:
1. have the Installation and Debugging difficulty on the overall structure of internal hair thorn device, the operating time of changing debugging is unfavorable for enhancing productivity near a class very much.
2. former knife bar reaches 8.7 meters most, assembles by 3 to 4 sections for adapting to different production specifications, fixing difficulty, and cutter head partly produces bigger swing and twisting, makes inner-burr cleaning requisite quality difficulty.
3. former knife bar is divided into three kinds according to different steel pipe specifications, be applicable to φ 212.5-φ 298.5mm, φ 312.5-φ 425.4mm, φ 437.5-φ 625mm respectively, every kind of specification has nearly 8 kinds of small dimensions according to thickness of steel pipe from 4.9mm-20mm again, be applicable to nearly tens kinds of the spare parts of different size different wall on the knife bar, consumed a large amount of financial resources, manpower and time for the preparation and the on-the-spot Installation and Debugging of spare part.
4. it is fragile that interior burr is chopped device off, and the former interior burr on the equipment is chopped device off and lost efficacy, causes the often stifled cutter of overlap, and burr is not removed and shut down frequent in causing.
5. cutter head damages easily, changes frequently, influences ordinary production speed.
6. original welding-seam guide roll can not normally play a role, and influences weldquality.
[summary of the invention]
