Abstract
The utility model discloses a steel pipe diameter expanding unit, comprising a washing station, a diameter expanding station and a post washing station. The utility model is characterized in that the three stations from the inlet tube direction is arranged vertically as the washing station, the diameter expanding station in the middle and the post washing station at the end, a rail is arranged horizontally through three stations, two pipe transportation trucks are arranged on the rail. A hydraulic cylinder is connected with the hydraulic system of the unit, the washing device is connected with a water supply system, a dual-line lubricating system and a set of spray lubricating system. The unit is provided with an electrical control system. The utility model has the advantages that the two pipe transportation trucks are responsible for feed in of the steel pipes, conversion and transmission of stations of steel pipes. Each apparatus of each station can achieve single acting and linkage; each station can work independently; three stations and two pipe transportation trucks also can achieve automatic combined operation.
Description
Technical field
The utility model belongs to the pipe expanding field, particularly a kind of pipe expanding unit.
Background technology
According to the requirement of the API of American Petroleum Institute standard, oil pipeline must pass through expanding technology with large straight-line joint submerged arc welding tube, and has stipulated the enlarging rate of hole enlargement steel pipe and the indexs such as precision after the hole enlargement.Straight-line joint submerged arc welding tube does not allow to use in oil transportation, tracheae line without hole enlargement.The effect of pipe expanding unit is: the hole enlargement of radially carrying out to steel pipe reaches accurate circularity and diameter; Eliminate the mixed and disorderly internal stress that steel pipe produces in the cold roll forming process, the distribution of internal stress is reached unanimity, thereby increase YIELD STRENGTH; Eliminate steel pipe because weld seam shrinks the bending that produces, the linearity of steel pipe is reached in the prescribed limit; The quality of butt welded seam is once checked.Along with the development of petroleum industry, oil transportation, tracheae line quicken all over the world to lay at present, and vertical masonry joint pipe production line is more and more.Because in the design of steel tube expansion, make and have many difficult problems, only have two families to provide this product at present in the world to the user.Expanding machine in newly-built three straight welded pipe production lines of China is all by the Meer company import of Germany.Because the height that expanding machine is produced monopolization causes the price of expanding machine very expensive.
Summary of the invention
The object of the present invention is to provide a cover integral layout rationally, each component function is perfect, can satisfy the pipe expanding unit of pipe expanding technical process.
For achieving the above object, solution of the present utility model is: a kind of pipe expanding unit, by the flushing station, the hole enlargement station, the afterflush station is formed, above-mentioned three stations vertically set gradually from the inlet pipe direction and are the flushing station, middle is the hole enlargement station, end is the afterflush station, run through horizontal three stations and be provided with track, described track is provided with two pipe carrying trucks, the hydraulic jack of described this unit is connected with hydraulic system, described flusher is connected with water system, a two line lubrication system and a cover oil foglubrication system, described this unit has also disposed a cover electric control system.
Above-mentioned pipe expanding unit, its two pipe carrying trucks are responsible for the station conversion of the sending into of steel pipe, steel pipe and are sent.Each mechanism of each station can realize single action and interlock; Each station also can work independently; Three stations and two pipe carrying trucks also can be realized automatic integration of operation.Before the hole enlargement,, must clear up the steel pipe inwall before the hole enlargement, therefore before the hole enlargement station, the flushing station must be set in order to remove the oxide skin that the steel pipe that retains on the steel pipe inwall produces and the purpose of foreign material protection hole enlargement head thereof in forming process.On this station, steel pipe washes with emulsion while rotating, and reaches the clean purpose of steel pipe inner wall cleaning.In the hole enlargement position, the device of finishing hole enlargement is the expanding machine main frame, and it is all keeping the bracing or strutting arrangement-pendulum roller and the backing roll of level to be made up of duplex actuator cylinder, boom tie, hole enlargement head and assurance boom tie and hole enlargement head under the hole enlargement state and under the non-hole enlargement state.In order to guarantee the cleaning of hole enlargement head, behind steel pipe of every expansion, the hole enlargement head is washed by hole enlargement head cleaner structure.After the hole enlargement,, be provided with the afterflush device for the steel pipe of cleaning is provided to subsequent processing, the afterflush device is arranged in the back of hole enlargement station, the steel pipe that enters this station is transported to interior shower nozzle and outer spray ring place by conveying roller, and flushing is clean with the inside and outside surface washing of steel pipe with emulsion while walking; Clean inner surface again with clear water when returning.Clean the back and steel pipe is lifted, carry out sky water by empty water device.Turn back to the inlet pipe position behind the empty water, transport unit by pipe carrying truck.
The utility model has the advantages that: except that the whole hole enlargement of finishing steel pipe.Because having increased straightener further improves the linearity of hole enlargement steel pipe; The flushing of preceding flusher and hole enlargement primary drying cleaning device has guaranteed the cleannes of hole enlargement head, has prolonged the life-span of hole enlargement head; Afterflush provides the steel pipe of cleaning for next procedure; Each work step is all realized working automatically by flow process under the control of advanced person's electric control system; The operation of two pipe carrying truck connection, efficient improves greatly.
