Abstract
The utility model discloses welding equipment for a carbon steel spiral welded pipe with a reinforcing rib. The welding equipment comprises an inner forming roller, a finished pipeline support wheel and a reinforcing rib forming positioning wheel, wherein a steel band which is discharged by a steel band discharge rack and a reinforcing rib material band which is discharged by a reinforcing rib material band discharge rack form the same included angle alpha with the inner forming roller, the alpha is an acute angle, the steel band directly winds the inner forming roller, and the reinforcing rib material band winds outside the steel band. When the inner forming roller is driven by power to rotate at uniform speed around the axial line, the steel band spirally winds the inner forming roller, the reinforcing rib spirally winds outside the steel band and moves backwards along the axial line of the inner forming roller, and a welding seam of the steel band and the reinforcing rib are welded into a finished pipeline by virtue of a high-frequency power supply, a high-frequency electrode A and a high-frequency electrode B. The welding seam of the steel band and the welding of the reinforcing rib are synchronously performed, and preprocessing of a convex rib on the steel band and then welding of the steel band after spiral winding are not needed, so that working procedures are reduced, and good ring stiffness can be guaranteed by adopting the thin-walled steel band combined with the reinforcing rib.
Description
Technical field

For above-mentioned technical problem, developed a kind of novel carbon steel spiral welded pipe with reinforcement, adopt thin-walled steel band just can guarantee the ring stiffness of body, and technique is simple, low cost of manufacture, intensity are reliable, and the utility model aims to provide a kind of welding equipment of manufacturing this New Type of Carbon steel spiral welded pipe that is exclusively used in.
For this reason, the technical scheme that the utility model adopts is: a kind of welding equipment for the carbon steel spiral welded pipe with reinforcement, comprise carbon steel spiral welded pipe body and reinforcement, described reinforcement is wrapped on carbon steel spiral welded pipe tube wall successively along the spirality seam of carbon steel spiral welded pipe body, and by this reinforcement, two plates at carbon steel spiral welded pipe body seaming position place are integrally welded, key is:
Described welding equipment comprises interior format roll, steel band discharging frame, reinforcement material strip discharging frame, finished product pipeline support wheel, reinforcement moulding locating wheel, high frequency electric source, and the high-frequency electrode A being connected with described high frequency electric source, high-frequency electrode B, the reinforcement material strip that the steel band that described steel band discharging frame is emitted, reinforcement material strip discharging frame are emitted forms identical angle α with interior format roll, and α is acute angle, described steel band is directly wrapped on interior format roll, and reinforcement material strip is wrapped in outside steel band; When described interior format roll is by power drive during around self axis uniform rotation, steel band spirality is wrapped on interior format roll, and reinforcement spirality is wrapped in outside steel band, and moves backward along the axis of interior format roll; Described reinforcement moulding locating wheel is positioned at the binding site place of reinforcement material strip and steel band, to guarantee that reinforcement material strip is just wrapped in the seaming position place of steel band, and just in time the seaming position place of steel band is covered, the seam of described steel band and reinforcement are welded as finished product pipeline by high frequency electric source, high-frequency electrode A, high-frequency electrode B, described finished product pipeline support wheel is positioned at the rear of format roll, for supporting the finished product pipeline having welded, moves backward.
As such scheme preferably, described steel band discharging frame is positioned at the left side of format roll, the right side that reinforcement material strip discharging frame is positioned at format roll.Convenient layout, guarantees that steel band that steel band discharging frame emits, the reinforcement material strip that reinforcement material strip discharging frame is emitted move smooth and easy, and convenient layout guarantees that the steel band that steel band discharging frame emits, the reinforcement material strip that reinforcement material strip discharging frame is emitted move smooth and easy.
The course of work of this equipment is as follows: before welding, first the steel heading end on steel band discharging frame is wrapped on interior format roll, again the reinforcement material strip termination on reinforcement material strip discharging frame is wrapped in outside steel band, locate by reinforcement moulding locating wheel the termination of reinforcement material strip, to guarantee that reinforcement material strip covers the seaming position place at steel band all the time, reinforcement moulding locating wheel installation site maintains static.Along with the axis uniform rotation of interior format roll around self, steel band very naturally spirality is wrapped on interior formed pipe, reinforcement material strip also very naturally spirality be wrapped in tube wall, rotation along with interior format roll, the seaming position of steel band and the reinforcement covering at seaming position place move together backward, and high-frequency electrode A, high-frequency electrode B transfixion all the time, thereby the seam of steel band and reinforcement are welded as to finished product pipeline.
Beneficial effect: the seam of steel band is synchronizeed and carried out with reinforcement welding, be that steel band is welded into body, reinforcement is welded on body and can once completes, do not need " on steel band, processing in advance convex tendon; after again ribbon spiral being wound around, be welded " as introduced in background technology, reduce operation, reduced manufacturing cost; Adopt thin-walled steel band just can guarantee the good ring stiffness of carbon steel spiral welded pipe in conjunction with reinforcement, further reduced manufacturing cost, and installation, convenient transportation.
