Description
Technical field
The present invention relates to steel-tube finishing field, in particular, is a kind of pipe end rounding device.
Background technology
With the progress of material science and metallurgical technology, pipeline industry is towards high discharge pressure and big
The direction of feed flow is developed.The intensity requirement more and more higher of pipeline steel tube, tube wall are more and more thicker, directly
Footpath is increasing, the accuracy of manufacture more and more higher of fished pipe, and this is all greatly promoted pipeline steel tube
The development of manufacturing technology.
Some iron and steel enterprises have Longitudinal SAW Pipe unit, abbreviation UOE units, the unit
The product for the being produced predominantly large-caliber gas-oil line pipe with high added value.Steel-tube finishing line
Be the steel pipe after welding is carried out machinery expanding, steel pipe hydraulic pressure, pipe end chamfered edge, steel pipe Non-Destructive Testing,
Steel pipe seal such as is checked the weight at the producing line of operation.Machinery expanding unit therein, mainly to the steel pipe after welding
Carry out internal diameter sizing, it is ensured that it is complete that steel pipe reaches the internal diameter size of requirement, caliber ovality size, steel pipe
Long linearity size.Recent years, line pipe was for the pipe end of steel pipe, pipe diameter ovality deviation
Require more and more higher (no more than 0.5%O.D., i.e. outer diameter of steel pipes 0.5%), one is for steel pipe
Uniform load is born, two is in order in the butt welding of line pipe job site, two steel pipes are docked
High precision, deviation are little, and efficiency of construction is high.UOE units are generally possible to meet the technical requirements such as ovality,
But as expanding rear steel pipe has roller-way conveying, material stress change, job site transport etc., often
Occur part steel pipe before exfactory inspection, job site ovality beyond product requirement situation.
Domestic existing pipe end full circle equipment is broadly divided into two kinds, one kind be in steel pipe manufactory on-site,
Equipment is fixed on certain region, drives rounding die to carry out steel pipe using gate frame structure, oil cylinder
The pipe end rounding machine of external-compression type pipe end full circle, such as Patent No. ZL201210527059.7, makes
Roller-way conveying steel pipe is used, steel pipe drives circular die with hydraulic jack in place afterwards, cylindrical to pipe end to carry out
Pressure formula full circle, rounding machine described in the patent for fixed, using track, active car, gate frame,
Roller-way conveying, rise and fall roller etc., can carry out full circle to the steel pipe of different length, different tube diameters, be related to
Steel pipe specification limit is big, and efficiency is higher, roller-lifting, main pressure head is carried out using hydraulic control system
Drive；It is another kind of to adopt jack full circle, i.e., rounding die is connected at very heavy knock-pin position, by thousand
Jin top is placed on steel duct and carries out internal expanding full circle, then rounding die and jack are connected, then
Action jack makes mold actions, and after reaching full circle purpose mould, jack are taken out from steel pipe.
But, using two kinds of above-mentioned equipment, there is following defect：
1. due to pipe end rounding machine be fixed apparatus, it is irremovable go out factory building, need it is larger
Weight of equipment and more complicated control system, hydraulic system is conventional hydraulic system, full circle master cylinder
Size is big, high equipment cost；Full circle step finish for one end full circle after the whole other end again.
2., using the method for jack full circle, equipment is simple, and input is little, but hand labor intensity is big,
Efficiency is low, and jack output pressure is little, to need big full circle power steel pipe to no effect, there is also full circle
After end, jack and mould fall down the potential safety hazard hurted sb.'s feelings.
3. liang equipment effectively cannot carry out whole to the steel pipe of Large Diameter Pipeline, particularly more than Φ 610mm
Circle.
