Abstract
The utility model discloses a three-roll size reducing mill assembly capable of quickly changing a roll frame, which solves the problem in a conventional three-roll size reducing mill assembly such as complicated operation when frame arranging and device changing are performed. The three-roll size reducing mill assembly includes a main drive (1), a quick gear coupler (2), a main engine seat (6) and a roll frame (4), wherein a lower positioning inclined block (8) is arranged on one side of the roll frame (4), and a compressing inclined surface (11) and a lower draw hook (100) are arranged on the other side of the roll frame (4); a hydraulic cylinder (14) is fixed on the main engine seat (6); a swing arm (12) is hinged onto the main engine seat (6) through a hinge shaft (13); one end of the swing arm (12) is hinged with the output shaft of the hydraulic cylinder (14), and the other end of the swing arm (12) is arranged between the compressing inclined surface (11) and the lower draw hook (100); and a positioning inclined block (5) arranged on the main engine seat (6) is in clearance fit with the lower positioning inclined block (8) on the roll frame (4). The three-roll size reducing mill assembly has a simple structure, and is convenient to maintain.
Description
Technical field
The present invention relates to a kind of metallurgy industry seamless steel pipe production, particularly relate to a kind of three-roll size reducing mill group of fast changeable roll stand.
Background technology
At present, in smelter seamless steel pipe rolling production equipment, size-reducing mill is one of crucial finishing equipment of seamless steel pipe rolling production.Steel pipe need finally be rolled into the seamless steel pipe finished product through size-reducing mill with tube reducing, rounding and sizing after the hot rolling.Three-roll size reducing mill group in the existing large-sized seamless steel pipe unit, its main engine bed adopt frame-type design, when configure chassis during with changing device more, exist weight big, and roll changing time is grown and the problem of complicated operation.
Summary of the invention
The invention provides a kind of three-roll size reducing mill group of fast changeable roll stand; Solved the three-roll size reducing mill group in the existing large-sized seamless steel pipe unit; In configure chassis with more during changing device, exist weight big, the problem of the long and complicated operation of roll changing time.
The present invention overcomes the above problems through following scheme:
A kind of three-roll size reducing mill group of fast changeable roll stand; Comprise main transmission, quick toe joint hand, main engine bed and roll stand, roll stand is provided with roll stand toe joint hand, and the left surface of roll stand is provided with down the location skewback; The right flank of roll stand is provided with the inclined-plane that compresses of roll stand; Compress the following drag hook that roll stand above the inclined-plane is provided with roll stand, on main engine bed, be set with hydraulic cylinder, swing arm is hinged on the main engine bed through hinge; One end of swing arm and the output shaft of hydraulic cylinder are hinged; The other end of swing arm is arranged between the following drag hook that compresses inclined-plane and roll stand of roll stand, and main engine bed is provided with the location ramp blocks of roll stand, and inclined-plane, the location activity of the following location skewback on inclined-plane, location and the roll stand of location ramp blocks cooperates.
On the left surface of described roll stand, be provided with and locate skewback, be provided with drag hook and compress the inclined-plane in the right flank upper end of roll stand.
The present invention is simple in structure, and is easy to maintenance, is particularly suitable for producing the three-roll size reducing mill group of heavy caliber seamless steel pipe.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Specific embodiment
A kind of three-roll size reducing mill group of fast changeable roll stand; Comprise main transmission 1, quick toe joint hand 2, main engine bed 6 and roll stand 4; Roll stand 4 is provided with roll stand toe joint hand 3; The left surface of roll stand 4 is provided with down location skewback 8, and what the right flank of roll stand 4 was provided with roll stand compresses inclined-plane 11, compresses the following drag hook 10 that roll stand above the inclined-plane 11 is provided with roll stand; On main engine bed 6, be set with hydraulic cylinder 14; Swing arm 12 is hinged on the main engine bed 6 through hinge 13, and an end of swing arm 12 and the output shaft of hydraulic cylinder 14 are hinged, and the other end of swing arm 12 is arranged between the following drag hook 10 that compresses inclined-plane 11 and roll stand of roll stand; Main engine bed 6 is provided with the location ramp blocks 5 of roll stand, and inclined-plane, the location activity of the following location skewback 8 on inclined-plane, location and the roll stand 4 of location ramp blocks 5 cooperates.
Left surface upper end at described roll stand 4 is provided with location skewback 7, is provided with drag hook 9 and compresses the inclined-plane in the right flank upper end of roll stand 4.
Place the station of roll stand on the base of the present invention according to steel rolling process Demand Design some (general more than 3); The Y direction location mouth that roll stand is arranged on each station; Location, inclined-plane, two location directions X hangs in an aligning mouth with roll stand and is placed on the base, starts hydraulic cylinder 14 and advances roll stand; Lean on the location, inclined-plane, location on the base, and the toe joint hand 2 of roll stand and 1 connection of the quick toe joint hand on the reductor.When rolling, hydraulic cylinder 14 locking roll stands, the inclined-plane, two location of each roll stand can overcome tilting moment and the vibrations when rolling.Hydraulic cylinder 14 abilities one cylinder is dual-purpose, can pull out the propelling roll stand, can play the effect that compresses roll stand again when rolling.
