Abstract
The invention discloses a rolling mill for rectangular steel tubes. The rolling mill comprises a base; the base is fixedly provided with a left rack and a right rack; the rolling mill comprises further a top roll, a bottom roll, a left roll and a right roll; the rolling mill also comprises an arched adjusting bracket and a cross beam connected with the upper end of the left rack and the upper end of the right rack; U-shaped chutes are respectively formed in the left rack and the right rack; two ends of the arched adjusting bracket are respectively arranged in the U-shaped chutes, and are in vertical sliding fit with the U-shaped chutes; the middle part of the arched adjusting bracket is provided with a lifting rod in screw-thread fit with the cross beam. According to the rolling mill disclosed by the invention, by connecting the cross beam with the left rack and the right rack, the racks form a rectangular frame structure on the whole; the racks are high in rigidity, so that the problem that the existing racks vibrate during rolling can be avoided; moreover, the arched adjusting bracket is connected with the left end and the right end of the top roll, and the top roll is adjusted to rise or fall through the lifting screw rod, so that the roll is convenient to adjust, the adjustment time is short, and the work efficiency is high.
Description
Technical field
The present invention relates to a kind of rolling equipment, particularly to a kind of milling train of rolling rectangular steel pipe.
Background technology
Rectangular steel pipe milling train includes left frame and right frame, described left frame and right frame are respectively arranged with topping roll,
Bottom roll, left roll and right roll.
In prior art, the left frame of rectangular steel pipe milling train and right frame are separated from each other, and frame integrally becomes u shape to tie
Structure, rigidity is poor, easily shakes, lead to steel tube surface quality poor in the operation of rolling.And it is the next on adjusting topping roll
When putting, need to adjust the screw rod on left frame and right frame, property easy to adjust is poor simultaneously, adjust time-consuming longer.
Content of the invention
In view of this, it is an object of the invention to provide a kind of rectangular steel pipe milling train, to solve rectangle thick stick pipe in prior art
The problems such as rigidity of frame of milling train is poor, roll property easy to adjust is poor.
Rectangular steel pipe milling train of the present invention, including base, described base is fixedly installed left frame and right frame, also includes
Topping roll, bottom roll, left roll and right roll, the two ends of described bottom roll are arranged on left frame and right frame, and left roll sets
Put on left frame, right roll is arranged in right frame；Also include arch adjusting bracket and be connected to left frame and right frame upper end
On crossbeam, described left frame and right frame are provided with u shape chute, the two ends of described topping roll are arranged on arch adjusting bracket
On two ends, the two ends of described arch adjusting bracket are arranged in u shape chute and slide up and down cooperation with u shape chute；Described arch is adjusted
The middle part of section frame is provided with the elevating lever with the cooperation of crossbeam screw thread, and described elevating lever is provided with locking nut；
The bolt of fixing arch adjusting bracket is provided with the side of described left socle and right support.
Further, the side side wall of described u shape chute is provided with the straight guide sliding up and down cooperation with arch adjusting bracket.
Beneficial effects of the present invention:
1st, rectangular steel pipe milling train of the present invention, it connects left frame and right frame so that frame is integrally rectangular by crossbeam
The lateral stressed performance of mount structure, left frame and right frame greatly enhances, and rigidity of frame is good, is avoided that existing frame was rolling
Vibration problems in journey.
2nd, rectangular steel pipe milling train of the present invention, it connects the left and right two ends of topping roll by arch adjusting bracket, is risen by one
Fall screw rod adjusts the lifting of topping roll, and roll is easy to adjust, adjusts and takes short, high working efficiency.
Brief description
Fig. 1 is the front view of rectangular steel pipe milling train of the present invention；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As illustrated, the present embodiment rectangular steel pipe milling train, including base 1, described base is fixedly installed left frame 2 He
Right frame 3, also includes topping roll 4, bottom roll 5, left roll 6 and right roll 7, the two ends of described bottom roll be arranged on left frame and
In right frame, left roll is arranged on left frame, and right roll is arranged in right frame；Also include arch adjusting bracket 8 and be connected to
Crossbeam 9 in left frame and right frame upper end, described left frame and right frame be provided with u shape chute, and the two of described topping roll
End be arranged on the two ends of arch adjusting bracket, the two ends of described arch adjusting bracket be arranged in u shape chute and with u shape chute on
Lower slider coordinates；The middle part of described arch adjusting bracket is provided with the elevating lever 10 with the cooperation of crossbeam screw thread, and described elevating lever sets
It is equipped with locking nut 11；
The bolt 12 of fixing arch adjusting bracket is provided with the side of described left socle and right support.
The present embodiment rectangular steel pipe milling train, it connects left frame and right frame so that frame is integrally rectangular by crossbeam
The lateral stressed performance of mount structure, left frame and right frame greatly enhances, and rigidity of frame is good, is avoided that existing frame was rolling
Vibration problems in journey.
And this rectangular steel pipe milling train connects the left and right two ends of topping roll by arch adjusting bracket, by a lifting screw
Adjust the lifting of topping roll, roll is easy to adjust, adjust and take short, high working efficiency.
As the improvement to the present embodiment, the side side wall of described u shape chute is provided with and downslide on arch adjusting bracket
The straight guide 13 of dynamic cooperation, is positioned the right position of arch adjusting bracket, can further improve the position of topping roll by straight guide 13
Put precision, be conducive to improving rolling quality.
Finally illustrate, above example only in order to technical scheme to be described and unrestricted, although with reference to relatively
Good embodiment has been described in detail to the present invention, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent, the objective without deviating from technical solution of the present invention and scope, and it all should be covered at this
In the middle of the right of invention.
