Abstract
Relate to steel pipe and manufacture a kind of high frequency in field and middle ERW roll, comprise upper left roller, upper right roller, ratio-frequency welded tube thorn sheet, middle steel pipes with straight thorn sheet and hexagon socket head cap screw, its ratio-frequency welded tube thorn sheet or middle steel pipes with straight thorn sheet are between upper left roller and upper right roller, and upper left roller, ratio-frequency welded tube thorn sheet or middle steel pipes with straight thorn sheet, upper right roller connect in aggregates by hexagon socket head cap screw.Left and right of the present utility model top roll and ratio-frequency welded tube thorn sheet, middle steel pipes with straight thorn sheet can dismantles and assemble, and to adapt to ratio-frequency welded tube, the feature of middle steel pipes with straight two kinds of different modes of production and demand respectively, do not need for different rolls is overlapped in its preparation two.
Description
Technical field
The utility model belongs to steel pipe and manufactures field.
Background technology
In high-frequency welded steel pipe technical process, band is after steel enters forming frame, makes band steel become pipe to weld by roll is continuously shaped.Although middle steel pipes with straight produces the profiled section sharing unit with high-frequency welded steel pipe, due to technologic difference, even if produce the steel pipe of same specification, two kinds of modes of production are not identical to the diameter of steel tube after welding compression roller yet.
Summary of the invention
The purpose of this utility model is to provide a kind of high frequency and middle ERW roll, and it is a kind of roll that can dismantle, and the roll formed after stinging sheet by replacing is for being applicable to the technological requirement of ratio-frequency welded tube or middle steel pipes with straight.
The technical solution of the utility model is:
The utility model comprises upper left roller, upper right roller, ratio-frequency welded tube thorn sheet, middle ERW thorn sheet, hexagon socket head cap screw, described ratio-frequency welded tube thorn sheet or middle ERW thorn sheet are between upper left roller and upper right roller, and upper left roller, ratio-frequency welded tube thorn sheet, upper right roller are connected into an entirety through after the through hole on upper left roller, upper right roller by hexagon socket head cap screw; Or upper left roller, middle ERW thorn sheet, upper right roller are connected into an entirety through after the through hole on upper left roller, upper right roller by hexagon socket head cap screw.
Described upper left roller and the end face of upper right roller respectively have a boss, and upper left roller and upper right roller are evenly equipped with 6 through holes.
The endoporus of described ratio-frequency welded tube thorn sheet and middle ERW thorn sheet matches with the boss of upper left roller, upper right roller respectively.
Advantage of the present utility model is as follows:
Left and right of the present utility model top roll and ratio-frequency welded tube sting sheet or middle steel pipes with straight thorn sheet can be dismantled and assemble, and ratio-frequency welded tube thorn sheet and middle steel pipes with straight sting sheet and can exchange, its ratio-frequency welded tube thorn sheet and middle steel pipes with straight thorn sheet adapt to the Liquified gas tanker of ratio-frequency welded tube and middle ERW two kinds of different modes of production respectively, are no longer necessary for two kinds of different modes of production and prepare the different roll of two covers.
Accompanying drawing explanation
Fig. 1 is the utility model ratio-frequency welded tube roll structure schematic diagram;
Fig. 2 is steel pipes with straight roll structure schematic diagram in the utility model.
Detailed description of the invention
In Fig. 1, upper left roller 1, upper right roller 3, ratio-frequency welded tube 2 are embedded in the middle of upper left roller 1, upper right roller 3, and 6 hexagon socket head cap screws 4 are through connecting in aggregates by upper left roller 1, ratio-frequency welded tube 2, upper right roller 3 after 6 through holes on upper left roller 1, upper right roller 3.For the production of ratio-frequency welded tube.
In Fig. 2: upper left roller 1, upper right roller 3, middle steel pipes with straight thorn sheet 5 is embedded in the middle of upper left roller 1, upper right roller 3, upper left roller 1, middle steel pipes with straight thorn sheet 5, upper right roller 3, through after 6 through holes on upper left roller 1, upper right roller 3, connect in aggregates by 6 hexagon socket head cap screws 4.For the production of middle steel pipes with straight.
