Description
Technical field
The utility model belongs to the ERW production equipment, is specially adapted to the anti-a kind of welding-line deviation prevention device of butt welded tube that reverses of straight welded pipe welding-seam.
Background technology
In existing straight welded pipe production line, the position of weld seam is to adjust by prerotation vane before welding at present, and this method of adjustment has following weak point:
1, waste product increases, and cost strengthens, and the unbalance stress of band and internal stress influence weld seam after welding of band also have torsion phenomenon during owing to moulding, cause the generation of waste product.
2, production efficiency is not high, and in a single day production line produces waste product, will handle, and the waste product cutting process is fallen, and this has just restricted the efficient of production line.
Summary of the invention:
The utility model is intended to the shortcoming weak point that exists in above-mentioned technology, and provides reasonable in design, compact conformation, and have the production efficiency height, a kind of welding-line deviation prevention device of butt welded tube that reduces production costs.
The purpose of this utility model is to adopt following technical scheme to realize: described welding-line deviation prevention device of butt welded tube, it is characterized in that: symmetrical installing can be along the slide block of chute slip in the chute at base top surface two ends, in the bottom of the two slide blocks manual slide block opening and closing mechanism of installing, the torsion roller mechanism corresponding with the position of processed pipe, that the symmetry installing is driven by worm and gear in the opposite flank on two slide block tops; Described each torsion roller mechanism that is driven by worm and gear is by worm gear, worm screw, handwheel, roll shaft, and torsion roller and roller seat are formed, and installs roll shaft in a side is uncovered roller seat, at roll shaft torsion roller is housed; With uncovered relative roller seat side on connect an end of worm-wheel shaft, the other end of worm-wheel shaft inserts in the slide block, worm gear shaft part two ends suit fixed cover in the slide block, affixed worm gear reaches the worm screw that is meshed with worm gear on the worm gear shaft part between two fixed covers, the end of worm screw stretches outside slide block, connects handwheel on the end stretching of worm screw; Realization is rotated handwheel with hand and is driven the torsion roller rotation.
Described each manual slide block opening and closing mechanism is made up of leading screw, screw, adjusting nut, dial and hand-operated tools, symmetry installing screw in the lateral surface of two slide blocks, connecting an end in two screws is that the left-handed other end is the leading screw of dextrorotation, one end of leading screw stretches outside slide block, on the bar section that leading screw stretches, connect adjusting nut, dial in regular turn, with the hand-operated tools rotational lead screw.Wherein be carved with the size of adjustable range size on the dial; Described hand-operated tools or remove with the spanner of clamping the leading screw head or with the cover that is enclosed within the leading screw head.
Described uncovered roller seat is "] " roller seat of shape framework.
Principle of the present utility model and operation are described below:
Because the skew of weld seam often takes place in the straight weld of welded tube when welding---cry weldering usually partially; In order to correct the skew of weld seam, just need provide reverse moment of torsion to the straight weld of welded tube; Therefore,, the axle center of torsion roller and the axle center of steel pipe are had a certain degree, make torsion roller produce frictional force with steel pipe when rotated, steel pipe is twisted by regulate two torsion rollers in the utility model with hand.By the above technical scheme of taking, realize the purpose of this utility model.
Compared with prior art, the utility model is not only reasonable in design, compact conformation, and have the production efficiency height, and reduce production costs and handling safety, use advantages such as very convenient.
