Abstract
The utility model discloses a limiting protective casing of a steel pipe. The limiting protective casing is applied on a flying saw for sawing the steel pipe. The key point of the limiting protective casing lies in the fact that the limiting protective casing of the steel pipe is added between a cylinder of the flying saw and the steel pipe, wherein the main body part of the protective casing takes cylindrical shape and one end of the protective casing is outwardly bent into a right-angle shaft shoulder. The limiting protective casing of the steel pipe added between the cylinder of the flying saw and the steel pipe reduces the distance by which the steel pipe deviates from the axis after entering the cylinder of the flying saw, improves the cutting and locating precision of the steel pipe and the stability in sawing, prolongs the service life of the blade of the flying saw, and boosts the sawing efficiency.
Description
Technical field
The utility model belongs to the welded tube production technical field, relates to a kind of limiting and protecting device, a kind of steel pipe position limitation protection cover of forging a knife of avoiding flying to saw when cutting off steel pipe of more specifically saying so.
Background technology
Development along with the welded still pipe production technology; more and more higher to the requirement that the welded tube scale flies to cut; because requirement on environmental protection; adopt rolling cut or milling to fly to saw to substitute saw-blade type in the past and fly saw in order to reduce the many welded tubes of noise factory; because in process of production; there are vibrations and crooked in steel pipe; fly to saw cylinder bucket arrival end itself and have registration roller and the location slips that steel pipe is located; but because its positioning accuracy is not high, the track instability of steel pipe operation, the distance of saw blade and outer surface of steel tube has very big fluctuation; the load change that saw blade bears during sawing is very big; when bearing excessive load, saw blade just may damage, and causes shut-down.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of steel pipe that can improve and cuts positioning accuracy, avoids flying to saw the steel pipe position limitation protection cover of forging a knife.
For solving the problems of the technologies described above; technical solution adopted in the utility model is: a kind of steel pipe position limitation protection cover; be applied in the flying on the saw of sawing steel pipe, its key is that to have set up main part between cylinder bucket and the steel pipe be the steel pipe position limitation protection cover that is converted into the right angle shaft shoulder outside cylindric, the end flying to saw.
The inboard arrival end of the shaft shoulder of described steel pipe position limitation protection cover is tapered.
Described steel pipe position limitation protection cover with fly to saw the cylinder bucket and be connected by bolt.
Described steel pipe position limitation protection cover is made by elastomeric material.
Adopt the beneficial effect that technique scheme produced to be: by flying to saw the steel pipe position limitation protection cover of setting up between cylinder bucket and the steel pipe; having reduced steel pipe enters and flies to saw the cylinder bucket and retrodeviate distance from axis; improved steel pipe cutting positioning accuracy; prolong the service life that flies saw blade, stability and cutting-rate when improving sawing.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is that the utility model uses schematic diagram;
Fig. 2 is a steel pipe position limitation protection nested structure schematic diagram;
Among the figure: 1, fly to saw the cylinder bucket, 2, steel pipe position limitation protection cover, 3, steel pipe, 4, bolt, 5, blade, 6, the walking guide rail, 7, fly saw, 8, the shaft shoulder.
The specific embodiment
A kind of steel pipe position limitation protection cover, be applied in the sawing steel pipe fly it is characterized in that on the saw: to have set up main part between cylinder bucket 1 and the steel pipe 3 be that the steel pipe position limitation protection that is converted into the right angle shaft shoulder 8 outside cylindric, the end overlaps 2 flying to saw.
The inboard arrival end of the shaft shoulder 8 of above-mentioned steel pipe position limitation protection cover 2 is tapered, is convenient to steel pipe and inserts steel pipe position limitation protection cover smoothly, and preferred cone angle is 25 °.
Above-mentioned steel pipe position limitation protection cover 2 with fly to saw cylinder bucket 1 and be connected by bolt 4.
The external diameter of preferred steel pipe position limitation protection cover 2 is according to the porch internal diameter design that flies to saw cylinder bucket 1, with the internal diameter that flies to saw cylinder bucket 1 porch quite but can insert the cylinder bucket smoothly.
The internal diameter of steel pipe position limitation protection cover 2 designs respectively according to the steel pipe 3 of different size, preferably than the big 20mm of corresponding steel pipe 3 external diameters.Steel pipe 3 enters and flies to saw the distance that cylinder bucket 1 retrodeviates from axis and will be limited in the 10mm like this.
It is more smaller than the internal diameter that flies to saw cylinder bucket 1 that the steel pipe position limitation protection overlaps the external diameter of 2 main parts; so that inserting smoothly, steel pipe position limitation protection cover flies to saw cylinder bucket 1; or equate with the internal diameter that flies to saw cylinder bucket 1, so that inserting, can better fix after flying to saw cylinder bucket 1 by steel pipe position limitation protection cover 2.
Above-mentioned steel pipe position limitation protection cover 2 is made by elastomeric material, preferably adopts nylon material to make, and wearability is good, and steel pipe is also had certain cushioning effect, reduces the sudden change of load, prolongs the service life that flies saw blade, improves operating rate.
Claims (4)
