The cutting frame has a simple structure, is low in cost, is time-saving and labor-saving during operation, is high in cutting efficiency and cutting quality, is safe and reliable, is not required to be maintained, has long service life and is particularly suitable for cutting a large-caliber iron pipe on a ship.
Description
Technical field
The utility model relates to a kind of cutting tool, specifically a kind of large-diameter pipe cutting rack.
Background technology
In the middle of the maintenance work aboard ship, the cutting pipe is regular work.With interior pipe, generally use toothless saw and manual pipe cutter to cut 100mm.But the pipe bigger to diameter, as: the ballast pipe on the ship, main drainpipe (diameter is more than 250mm mostly) etc., just can only cut with manual cutter.But use the big-inch pipe after the cutting of manual cutter, owing to hull rocks or reason such as misoperation, not only the end face after the cutting is uneven, and is prone to cut the cross section of pipe tiltedly, so often will carry out after-treatment to the pipe after cutting.And the process need of after-treatment is polished cutting section with emery wheel and end face is polished flat straight the time, thereby has caused the phenomenon that can't accurately hold the length of pipe, thereby brings very big trouble for blanking and driven dimension.Simultaneously because pipe diameter is bigger, so bruting process wastes time and energy more.
The utility model content
The purpose of the utility model just provides a kind of large-diameter pipe cutting rack, to solve the uneven and not straight problem of existing big-inch pipe cutting end face.
The utility model is achieved in that a kind of large-diameter pipe cutting rack; The inboard of closure frame is along being provided with by two fixed block supporting mechanisms and the three-point fix sliding support mechanism that the movable pulley supporting mechanism is formed, and the outside of said framework is along being provided with the cutter fixed mount that the fixed air burning torch is used.
Said movable pulley supporting mechanism is that the side at movable grillage is fixed with the sister block supporting mechanism; Opposite side at said movable grillage is fixed with screw rod; Said screw rod cross-under is on the side edge of said framework; On said screw rod, be socketed with the compression spring, the adjustment nut is screwed on the exposed junction of said screw rod; On the edge, inboard of said framework, be fixed with guide rail, said movable grillage and said guide rail slide and join.
Said fixed block supporting mechanism is the sister block supporting mechanism, to prevent the scarfing sideslip.
Said sister block supporting mechanism is to be connected to bearing respectively at the two ends of connecting axle.
Edge, the outside at said framework is provided with handle.
The utility model is the periphery that framework is socketed in the heavy caliber iron pipe; Be supported on the tube wall through the three-point fix sliding support mechanism, on the cutter fixed mount, fix cutter, and the position that the cutter nozzle alignment will be cut; After lighting cutter; Slow rotating frame can drive cutter and carry out circumference along the iron pipe tube wall and rotate, thereby cuts out that end face is smooth, the line of cut of cross section and iron pipe axis normal.
The characteristics of the utility model are following:
1, when cutting can cutoff, because cutting distance and cutting angle are adjusted before cutting and fixed.
2, the cutting end face of iron pipe is straight smooth, does not have uneven phenomenon; Pipe just scales off and can use, and without grinder buffing, size is accurate, needs how long how long just to cut, and does not have deviation.Because line of cut configures before cutting, rotation direction is again consistent, does not have a deviation so cutting slit width is consistent.
3, cutting is during pipe, is socketed in this cutting rack on the pipe to get final product, and is convenient to use; Without turne tube, it is motionless that the people stands in a position during cutting, with the hands evenly operates this cutting rack, just can cut away pipe like a cork, simple to operate, time saving and energy saving, can not rock and influence cut quality with hull.
4, in cutting process, the cutting torch of cutter can be along with under rotation direction forwards to, and just the cutting torch mouth rushes to, but the residue of blowing down needn't worry gas cutting the time causes fire extinguishing in the gravity fall of self on cutting torch.Because the adjustment of the direction of cutting torch configures before the cutting, it has an angle of chamfer, and the power of blowing is forward arranged naturally, so residue can not drop on the cutting torch, can not cause the fire extinguishing phenomenon.
5,,, can not misplace as long as cutter is return again gas cutting once again for the processing of not cutting the place.
6, be easily understood, at a glance can, easy to operate, quick.
7, cutting efficiency is high, and cut quality is good, and is safe and reliable, do not have maintenance, long service life.
The utility model is simple in structure, and is with low cost, and it is time saving and energy saving to operate; The cross section is smooth, can directly use, and can save conventional end face levelling and grinder buffing operation of cutting after managing; Improve the operating efficiency of section pipe, be particularly suitable for the cutting operation of the heavy caliber iron pipe on the steamer.
