Due to the mode, the roller is flexible in structure, a work layer can be disassembled and changed, the production schedule can not be influenced, each part is made from different materials, and the roller is less in manufacture cost.
Description
Technical field
The present invention relates to the roll technology field, particularly relate to a kind of roll of being convenient to change.
Background technology
Roll is the strength member on steel rolling mill's rolling mill, and the pressure that produces when utilizing a pair of or one group of roll to roll rolls the stone roller steel, and it mainly bears the sound load when rolling, wearing and tearing and influence of temperature variation.For satisfying the user demand that steel rolling is produced, the body of roll requires to have the good quality work layer of high wear-resistant, anti-strip, anti-surface coarsening.Existing roll adopts integral structure mostly, and structure is more inflexible, and material is single, and manufacturing cost is high, repairs more loaded down with trivial details.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of roll of being convenient to change, and can solve the defective that exists in the prior art, and structure is flexible, and working lining can change, and manufacturing cost is little.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of roll of being convenient to change is provided, comprises: the roll central shaft be arranged on the roll body on the said roll central shaft, said roll body one end is provided with a plurality of grooves; Said roll central shaft is provided with the projection that a plurality of and said groove matches; The said roll body outside is provided with the work collars, and said work collars comprises the fastening zone at workspace and two ends, and said fastening zone thickness is less than workspace thickness; Said fastening zone is provided with trip bolt; Said trip bolt runs through said fastening zone and pierces into the roll body interior, and said projection is provided with screw, and said screw runs through said projection and gets into the inside of said roll body.
In preferred embodiment of the present invention, said roll central shaft adopts cast iron materials to process.
In preferred embodiment of the present invention, said roll body adopts structure steel material to process.
In preferred embodiment of the present invention, said work collars adopts Hardmetal materials to process.
In preferred embodiment of the present invention, said trip bolt number is 5 ~ 12.
In preferred embodiment of the present invention, the workspace thickness of said work collars is 1/3rd of roll body thickness.
The invention has the beneficial effects as follows: the roll of being convenient to change that the present invention discloses, structure is flexible, and working lining can change, and does not influence manufacturing schedule, and each several part adopts different materials, and manufacturing cost is little.
Description of drawings
Fig. 1 is the structural representation of the present invention's roll one preferred embodiment of being convenient to change;
The mark of each parts is following in the accompanying drawing: 1, roll central shaft, 2, the roll body, 3, groove, 4, projection, 5, the workspace, 6, fastening zone, 7, trip bolt, 8, screw.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of roll of being convenient to change comprises: roll central shaft 1 be arranged on the roll body 2 on the said roll central shaft 1, said roll body 2 one ends are provided with a plurality of grooves 3; Said roll central shaft 1 is provided with the projection 4 that a plurality of and said groove 3 matches; Said roll body 2 outsides are provided with the work collars, and said work collars comprises the fastening zone 6 at workspace 5 and two ends, and said fastening zone 6 thickness are less than workspace 5 thickness; Said fastening zone 6 is provided with trip bolt 7; Said trip bolt 7 runs through said fastening zone 6 and pierces into roll body 2 inside, and said projection 4 is provided with screw 8, and said screw 8 runs through said projection 4 and gets into the inside of said roll body 2.
After said work collars uses through long-term, certain damage is arranged, can disassemble, deliver to manufacturer's maintenance, change new work collars simultaneously, continue to use, can not incur loss through delay the manufacturing schedule of enterprise, flexible.
Said roll central shaft 1 adopts cast iron materials to process.
Said roll body 2 adopts structure steel material to process.
Said work collars adopts Hardmetal materials to process.
Said roll central shaft 1, roll body 2 and work collars adopt material different, and than the roll of integral type, manufacturing cost is lower.
Said trip bolt 7 numbers are 5 ~ 12, make work collars and said roll body 2 strong bonded together.
The roll of being convenient to change that the present invention discloses, structure is flexible, and working lining can change, and does not influence manufacturing schedule, and each several part adopts different materials, and manufacturing cost is little.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
