Description
Technical field
The present invention relates to a kind of steel pipe inner wall mass defect treating apparatus, especially relate to a kind of Steel pipe inner wall treatment device penstock installation mechanism.
Background technology
Accurate seamless stainless steel tubing tube-making process is by circular pipe blank, and perforation, extends, sizing, annealing, cold rolling, annealing, cold-drawn, the operation such as normalizing and tempering composition, steel pipe inner wall mass defect common in process of production has crackle, infolding, scabs, pockmark, scratch and roughness excessive etc.Steel pipe inner wall mass defect will delay subsequent handling as processed not in time, pipe performance is had an impact, greatly can affect follow-up pipe finished qualification rate, in order to improve the accurate small-caliber seamless steel pipe lumber recovery of high added value, at High Precision Cold, in operation, the inwall quality of pipe checked before the processing such as cold-drawn and check to and necessary process need be carried out to the blemish of pipe, thus ensure that pipe orifice is without mass defects such as pits, it is the basic premise guaranteeing that steel pipe's production blank used conforms to quality requirements, be reduction of production cost, improve production efficiency, improve one important measures of product qualified rate.
The inwall quality surface defect of steel pipe is cleared up.Pickling, shot-peening or ball blast that both at home and abroad the relevant many employings of internal face process are traditional, strip off the skin process.These traditional processing methods all also exist problems: the physical effects of the spent acid waste gas one, produced during pickling to environment and direct labor is very large, its production environment is severe, spent acid waste gas directly affects ambient air, water, soil, and the processing cost of spent acid is very high; Two, shot-peening or ball blast produce a large amount of dust in process of production, cause the working environment of workshop equally very severe, and while surface cannot clean out completely, also cause inner wall surface to form more pockmarks, directly have influence on the quality of tubing; Three, stripping off the skin is utilize electromechanical assembly, grinding head selects conventional plane colyliform emery wheel grinding-head to steel surface grinding process, not only mechanicalness noise is large in use for this type of endoporus sanding apparatus, operating efficiency is not high, and often because endoporus hole depth difference causes polishing not in place, and inner wall coarse after process, do not reach treatment effect.In addition, substantially cannot process by structure and space constraint, shot-peening, ball blast, the inwall quality treatment stripped off the skin for small-bore steel pipe.
CN201010267812 was once disclosed a kind of minimizing technology of steel tube surface oxide skin, CN201110242186 was also once disclosed a kind of descaling process of solid drawn tube surfaces externally and internally high-pressure water jet cold conditions simultaneously, all disclose a kind of mode theory adopting the mode of water jet to carry out steel pipe internal-surface process in two patents, but do not disclose feasible facilities and equipment structure.CN201310005329 once disclosed a kind of steel pipe inner wall cleaning device, also be adopt the mode of water jet to carry out steel pipe internal-surface process, but this device structure is complicated and be only suitable for the steel pipe inner wall process of Large Diameter Pipeline, the defect processing of single-piece steel pipe can only be carried out simultaneously, the batch process to steel pipe cannot be realized.
Based on this problem, also there is no a kind of good technology and equipment for the process of caliber pipe inwall surface quality at present.Energy high efficiency, the solution caliber pipe inwall surface quality defect problem of low cost.
In order to solve the problem, applicant devises a kind of steel pipe inner wall mass defect treating apparatus, it comprises the housing of a strip, the penstock installation mechanism that can realize installing many steel pipe parallel interval supportings is provided with in housing, housing is also provided with an installation slide unit, multiple in hard elongated tubular and for parallel interval setting of described steel pipe fluid jet nozzle entirety, steel pipe fluid jet nozzle afterbody is fixed on to be installed on slide unit and can be connected by feed liquor flexible pipe and waterjet machine liquid outlet, installing slide unit is engaged on the guide rail of suitable shell length direction setting slidably, installing slide unit can drive each steel pipe fluid jet nozzle to enter into the pending steel pipe of the correspondence after installing vertically along slide, on housing, penstock installation mechanism is also provided with for the steel pipe block piece spacing to pending steel tube end part away from installation one end, slide unit direction.
Like this, namely can adopt disposable many steel pipes are installed side by side after, adopt open water jet machine again, multiple steel pipe fluid jet nozzle is driven to enter into corresponding pending steel pipe separately by mobile slide unit of installing, by means of abrasive particle and inner wall surface high velocity impact, produce erosion, shearing, reach the object removing slender metal pipe inner wall surface quality defect, realize the batch process to steel pipe inner wall.There is structure simple, easy to operate, process feature efficiently.
But wherein, how described penstock installation mechanism should design, just can make it have structure simple, facilitate installation and the rotation of steel pipe, to improve the feature for the treatment of effect, become the problem needing to consider to solve.
