Abstract
The utility model relates to a three-roller skew rolling mill, which comprises a machine frame, a roll adjustment device, and a guide plate system. The machine frame comprises a machine cover and a machine base. The guide plate system comprises a guide plate and a guide plate bracket. The guide plate is fixed on the guide plate bracket of the machine frame. The roll adjustment device is arranged in the machine base. The roll adjustment device comprises a hydraulic motor, a shaft coupling, a driving device, press screws, and coupling parts of roll boxes. The hydraulic motor is connected with the driving device through the shaft coupling. The driving device is connected with the press screws. The three-roller skew rolling mill is characterized in that three roll boxes are arranged in the machine base; and three rollers are respectively arranged in the three roll boxes; and the three rollers are arranged in an inverse triangle shape with 120 degrees between every two rollers. Because therollers are arranged in the inverse triangle shape, the three-roller skew rolling mill greatly shortens the length of the driving shaft of the rollers, reduces the rotational inertia during driving process, and reduces energy consumption.
Description
Technical field
The utility model relates to a kind of roll seamless steel tube equipment, especially a kind of novel three-roll cross rolling mill.
Background technology
Existing large and medium-sized three-roll cross rolling mill is three rolls and becomes equilateral triangle to arrange, promptly arranges a roll in cover, and arrange two rolls in support.Backstage at milling train is provided with the top, and the top becomes pass that pipe is rolled with three roll stacks.Its shortcoming is: because the weight of the cover of frame and support is approaching, and is furnished with a roll on the cover, make that the overall weight of cover is very big, be not easy to lifting and change roll.
Summary of the invention
The purpose of this utility model is to provide a kind of three-roll cross rolling mill for the defective that overcomes above-mentioned prior art existence.
The technical scheme that adopts is:
A kind of three-roll cross rolling mill, three-high mill comprise frame, roll adjusting device, guide plate system, and described frame comprises cover and support, and described guide plate system comprises guide plate and guide plate frame, and guide plate is fixed on the guide plate frame on the frame; Described roll adjusting device is arranged in the support, described roll adjusting device comprises that hydraulic motor, shaft coupling, transmission device press down screw and roll-box coupling component, hydraulic motor connects by shaft coupling and transmission device, transmission device and housing screw connect, it is characterized in that being provided with in the described support three roll-boxes, three rolls are installed in respectively in three roll-boxes, and three rolls are mutually hexagonal angle, and are del and arrange.
Milling train described in the utility model has the following advantages:
1, frame is reasonable in design, and the weight of cover only accounts for the 20-30% of support weight, and cover weight is lighter, is easy to lifting.
2, three rolls are installed in the support, are convenient to the replacing operation of roll.
3, because roll adopts inverted-triangular to arrange, make the propeller shaft length of roll significantly shorten, reduced the rotary inertia in the transmission process, reduced energy consumption.
4, because roll has feed angle and rolling angle simultaneously, make mill speed higher.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the structural representation of the utility model roll adjusting device.
The specific embodiment
A kind of three-roll cross rolling mill comprises frame, roll-box, roll adjusting device, guide plate system.Frame is made of cover 1 and support 2, and cover 1 relative support 2 weight are less, and roll 3 is installed in respectively in separately the roll-box 4, and three rolls are mutually hexagonal angle, and roll 3 has the rolling angle feed angle simultaneously, and roll-box 4 is installed in the support 2.Position corresponding with roll-box 4 in support 2 is equipped with roll adjusting device 5, roll adjusting device 5 is made up of hydraulic motor 8, shaft coupling 9, transmission device 10, housing screw 11 and roll-box coupling component 12, hydraulic motor 8 connects by shaft coupling 9 and transmission device 10, transmission device 10 connects with housing screw 11, finishes the axially-movable of housing screw 11.Roll adjusting device 5 is connected with roll-box 4 by roll-box attaching parts 12, and its housing screw 11 acts on the roll-box 4, finishes the adjustment of roll 3.Guide plate 6 is installed between three rolls, and guide plate 6 is fixed on the guide plate frame 7 on the frame.
