Description
Technical field
The utility model relates to seamless steel pipe pipe mill equipment technical field, relates in particular to pipe mill internal core rod bracing or strutting arrangement, is specially a kind of three-roller type plug bracing or strutting arrangement.
Background technology
In the roll seamless steel tube process, pipe mill inside processes by the plug supporting steel pipe and to steel pipe internal-surface, plug is fixed by bracing or strutting arrangement, existing plug bracing or strutting arrangement is three roller tight-holding type supporting constructions, roller-way and plug contact-making surface are little, cause plug to slide, depart from rolling centerline easily; The plug bracing or strutting arrangement of pipe mill inside need regularly replace, and the centre deviation of the fixed center of bracing or strutting arrangement and rolling centerline is difficult to regulate in its installation process; Simultaneously, roller-way is that rigidity contacts with plug, in the process of plug rollback, is sliding friction, mandrel surface serious wear between roller shell and the plug.
Technical scheme
At the problems referred to above, the utility model provides a kind of three-roller type plug bracing or strutting arrangement, and its fixed center that can guarantee plug is positioned at rolling centerline, when replacing, fittable slackening device, centre deviation is regulated simple and convenient, and effectively reduces roller-way to the wearing and tearing of mandrel surface.
Its technical scheme is such, a kind of three-roller type plug bracing or strutting arrangement, it comprises bracing frame, hydraulic jack, swing arm one, swing arm two, swing arm three, connecting rod one, connecting rod two and three groups of roller-ways, the support frame as described above end face evenly is provided with three groups of connecting axles by the equilateral triangle shape, described swing arm one, described swing arm two and described swing arm three are installed on the connecting axle by connection bearing, described swing arm two is connected by connecting rod one with described swing arm one, described swing arm three is connected by connecting rod two with described swing arm one, described hydraulic jack output shaft and described swing arm one are hinged, it is characterized in that: the vertical both sides of support frame as described above are equipped with and highly regulate liner plate and left and right adjusting liner plate, described height is regulated liner plate by the feet bottom surface of bolting in the vertical both sides of support frame as described above, described left and right adjusting liner plate by bolting in the vertical both sides of support frame as described above, and being positioned at described feet bottom, described roller-way and described plug contact-making surface are arc.
It is further characterized in that:
Fixedly there is described roller-way described swing arm one, described swing arm two and described swing arm three ends by the semiaxis seat;
Described roller-way comprises roller shell, back shaft, conical bearing one and conical bearing two, and described roller shell passes through two ends
Described conical bearing one is installed, conical bearing two is fixed on the described back shaft, described back shaft is installed on the described semiaxis seat;
Described roller shell surface is the indent arc;
Described connecting rod one and described swing arm one, described swing arm two pin joints, described connecting rod two and described swing arm one, described swing arm three pin joints.
After adopting the utility model, its beneficial effect is: the vertical both sides of bracing frame setting height(from bottom) is regulated liner plate and left and right adjusting liner plate, when periodic replacement, fittable slackening device, can and highly regulate liner plate the fixed center of bracing or strutting arrangement is finely tuned by the left and right adjusting liner plate, the fixed center of guaranteeing bracing or strutting arrangement is positioned on the rolling centerline, regulates simple and convenient; The roller shell surface is the indent arc, and roller shell and plug contact-making surface are big, effectively stationary core rod, prevent that plug from departing from rolling center; Simultaneously, roller shell is installed on the back shaft by bearing, and in the process of plug rollback, rolling between plug and roller shell contacts, and reduces the surface abrasion of plug greatly.
