Abstract
The invention discloses a rhombic tube rolling mill rack, including a horizontal rack on which s left roller and a right roller are installed, and a vertical rack on which an upper roller and a lower roller are installed, wherein the horizontal rack includes a pedestal, a left support plate and a right support plate are arranged at two ends of the pedestal respectively, a crossbar fitting with the upper ends of the roller shafts of the left and right rollers in a sliding manner is arranged on the left and right support plates. According to the rhombic tube rolling mill rack, the upper ends of the roller shafts of the left and right rollers are supported by the left and right support plates and the crossbar, the stress performance of the rollers can be greatly improved, and thereby the left and right rollers are prevented from shaking, deflecting and loosening in long-term use, and the rolling quality can be effectively improved.
Description
Technical field
The present invention relates to a kind of rolling equipment, particularly a kind of milling train of rolling rectangular steel pipe.
Background technology
Rhombus pipe-mill frame comprise the horizontal frames of installing left and right roll and install, the upright frame of bottom roll, horizontal frames and upright frame roll line separate layout successively.
Due to left and right roll vertical be arranged on horizontal frames, the horizontal impact power of steel pipe can be subject in left and right roll in the operation of rolling, and left and right roll is fixed on horizontal frames near its lower end, its ability of bearing longitudinal impact force is poor, in Long-Time Service, easily cause left and right roll deflection and loosening problem, have a strong impact on rolling quality.
Summary of the invention
In view of this, the object of this invention is to provide a kind of rhombus pipe-mill frame, with to solve in prior art the flat impulsive force of left and right roll water resistant on horizontal frames poor, easily produce deflection and loosening problem.
Rhombus pipe-mill frame of the present invention, comprise the horizontal frames installing left roll and right roll and the upright frame installing roll and bottom roll, described horizontal frames comprises base, the two ends of described base are provided with left support plate and right support plate, described left support plate and right support plate are provided with the cross bar be slidably matched with the roll shaft upper end of left roll and right roll.
Further, described cross bar is also provided with connecting plate, is provided with bar-shaped trough in the middle part of described connecting plate, the two ends of described connecting plate are provided with thread bush, be provided with cross-brace screw in described thread bush, the end of described supporting screw withstands on upright frame.
Further, described rhombus pipe-mill frame also comprises the left slide and right slide that are connected with the roll shaft lower end of left roll and right roll respectively, described base is provided with the pilot hole be slidably matched with left slide and right slide, described base is also provided with the adjusting screw(rod) with left slide and right slide threaded engagement, contrary with the rotation direction of two sections of screw threads that left slide and right slide coordinate on described adjusting screw(rod).
Beneficial effect of the present invention:
Rhombus pipe-mill frame of the present invention, it is supported by left support plate, right support plate and the cross bar roll shaft upper end to left and right roll, the square stress performance of level of raising roll that can be very large, thus can avoid left and right roll in Long-Time Service, occur vibrations, deflection and loosening problem, effectively can improve rolling quality.
Accompanying drawing explanation
Fig. 1 is the front view of rhombus pipe-mill frame of the present invention;
Fig. 2 is the cross-sectional schematic along A-A in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment rhombus pipe-mill frame, comprise the horizontal frames installing left roll 1 and right roll 2 and the upright frame 3 installing roll and bottom roll, described horizontal frames comprises base 4, the two ends of described base are provided with left support plate 5 and right support plate 6, described left support plate and right support plate are provided with the cross bar 8 be slidably matched with roll shaft 7 upper end of left roll and right roll.
The present embodiment rhombus pipe-mill frame, it is supported by left support plate, right support plate and the cross bar roll shaft upper end to left and right roll, the stress performance of raising roll that can be very large, thus can avoid left and right roll in Long-Time Service, occur vibrations, deflection and loosening problem, effectively can improve rolling quality.
As the improvement to the present embodiment, described cross bar is also provided with connecting plate 9, bar-shaped trough is provided with in the middle part of described connecting plate, roll shaft 7 upper end of left roll and right roll is arranged in bar-shaped trough, the two ends of described connecting plate are provided with thread bush 10, be provided with cross-brace screw 11 in described thread bush, the end of described supporting screw withstands on upright frame.In the operation of rolling, cross-brace screw 11 can apply cross-brace power in breaker roll axle upper end, thus can further improve the performance that left roll and right roll bear cross force, avoids roll in the operation of rolling, occur vibrations, deflection and loosening problem.
As the improvement to the present embodiment, described rhombus pipe-mill frame also comprises the left slide 12 and right slide 13 that are connected with the roll shaft lower end of left roll and right roll respectively, described base is provided with the pilot hole be slidably matched with left slide and right slide, described base is also provided with the adjusting screw(rod) 14 with left slide and right slide threaded engagement, contrary with the rotation direction of two sections of screw threads that left slide and right slide coordinate on described adjusting screw(rod), when needing the steel pipe of rolling different size, the relative position of left slide 12 and right slide 13 is regulated by adjusting screw(rod), to install different rolls, regulate simple and convenient, consuming time short.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
