Description
Technical field
The utility model belongs to seamless steel pipe preparing technical field, particularly relates to a kind of seamless steel pipe tube reducing former.
Background technology
At present, in smelter seamless steel pipe rolling production equipment, stretch-reducing mill and sizing mill are the crucial finishing equipments of seamless steel pipe rolling production.What both can be used for final products determines tube reducing, plays tube reducing effect after also can being arranged in punch.After hot rolling, steel pipe needs are through size-reducing mill by tube reducing, rounding and sizing, are finally rolled into seamless steel pipe finished product.Traditional three-roll size reducing mill, the seamless steel pipe after tube reducing runs unstable, and does not obtain corresponding cooling down operation after tube reducing, seamless steel pipe is made to can not get good molding effect like this, meanwhile, when reducing mill runs, noise is also very large, often causes the communication between shop worker to cause puzzlement.
Summary of the invention
The utility model provides a kind of seamless steel pipe a tube reducing former, with solve propose in above-mentioned background technology problem.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of seamless steel pipe a tube reducing former, comprise forebay, afer bay, opening between forebay and afer bay subtracts machine and motor, the output shaft of motor is by shaft coupling connection reducer, the output shaft of decelerator connects the roll stacks in roll stand by shaft coupling, accelerator lower end is provided with a word frame-shaped bearing, bearing inner transverse is provided with fore-stock, fore-stock is provided with carrying roller, the end of fore-stock connects roll stand, the rear end of roll stand is provided with outlet guide pin bushing, turning set is provided with in outlet guide pin bushing, and be provided with bearing between outlet guide pin bushing and turning set, the end of outlet guide pin bushing is provided with after-poppet, after-poppet is provided with carrying roller, the end of after-poppet connects cooling bath, cooling bath is provided with import.
Described outlet guide pin bushing by Flange joint on roll stand.
Support is provided with between described motor and roll stand.
Described carrying roller is connected with motor by chain.
Described cooling bath is built with the one in cooling fluid or water.
Described forebay and afer bay inside are provided with muffler.
The beneficial effects of the utility model are: in the workshop that seamless steel tube reducing is shaping, reasonable in design, and be skillfully constructed novelty, turning set is provided with in described outlet guide pin bushing, rotary sleeve rotates in outlet guide pin bushing, seamless steel pipe can be made to rotate in rotary sleeve, and do not affect outlet guide pin bushing; The muffler of machine frame inside can alleviate the noise that seamless steel pipe is in operation; Carrying roller in frame can make seamless steel pipe stable, there will not be the situation of landing; Be convenient to safeguard, maintenance, reducing maintenance and maintaining needs loaded down with trivial details step and longer time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further: the utility model provides a kind of seamless steel pipe a tube reducing former, comprise forebay 12, afer bay 7, opening between forebay 12 and afer bay 7 subtracts machine and motor 2, the output shaft of motor 2 is by shaft coupling connection reducer 1, the output shaft of decelerator 1 connects the roll stacks in roll stand 3 by shaft coupling, accelerator lower end is provided with a word frame-shaped bearing 10, bearing 10 inner transverse is provided with fore-stock, fore-stock is provided with carrying roller 11, the end of fore-stock connects roll stand 3, the rear end of roll stand 3 is provided with outlet guide pin bushing 4, turning set is provided with in outlet guide pin bushing 4, and be provided with bearing between outlet guide pin bushing 4 and turning set, the end of outlet guide pin bushing 4 is provided with after-poppet, after-poppet is provided with carrying roller 11, the end of after-poppet connects cooling bath 6, cooling bath 6 is provided with import 5.Described outlet guide pin bushing 4 by Flange joint on roll stand 3.Support is provided with between described motor 2 and roll stand 3.Described carrying roller 11 is connected with motor by chain.Described cooling bath 6 is built with the one in cooling fluid or water.Described forebay 12 and afer bay 7 inside are provided with muffler.
Seamless steel pipe 8 after hot rolling is positioned on the carrying roller 11 of forebay 12, carrying roller 11 rotates and drives seamless steel pipe 8 to move forward, enter roll stand 3, simultaneously motor 2 drives decelerator 1 decelerator 1 to drive roll stacks work in roll stand 3, thus seamless steel pipe 8 is carried out tube reducing operation, seamless steel pipe 8 after tube reducing spreads out of in outlet guide pin bushing 4, and the carrying roller 11 being positioned at afer bay 7 afterwards enters cooling bath 6 from import 5 again, completes one-shot forming operation.
The utility model is used in the shaping workshop of seamless steel pipe 8 tube reducing, reasonable in design, and be skillfully constructed novelty, turning set is provided with in described outlet guide pin bushing 4, rotary sleeve 9 rotates in outlet guide pin bushing 4, and seamless steel pipe 8 can be made to rotate in rotary sleeve 9, and does not affect outlet guide pin bushing 4; The muffler of machine frame inside can alleviate the noise that seamless steel pipe 8 is in operation; Carrying roller 11 in frame can make seamless steel pipe 8 stable, there will not be the situation of landing; Be convenient to safeguard, maintenance, reducing maintenance and maintaining needs loaded down with trivial details step and longer time.
