Description
Technical field
The utility model relates to the roll technology field, particularly relates 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 Dynamic And Static Loads when rolling, the impact of wearing and tearing and variations in temperature.The user demand of producing for satisfying steel rolling, the body of roll require 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.
The utility model content
The technical problem that the utility model mainly solves provides a kind of roll of being convenient to change, and can solve the defective that exists in the prior art, flexible structure, and working lining can change, and manufacturing cost is little.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of roll of being convenient to change is provided, comprise: roll central shaft and the roll body that is arranged on the described roll central shaft, described roll body one end is provided with a plurality of grooves, described roll central shaft is provided with the projection that a plurality of and described groove matches, the described roll body outside is provided with the work collars, described work collars comprises the fastening zone at workspace and two ends, described fastening zone thickness is less than workspace thickness, described fastening zone is provided with trip bolt, described trip bolt runs through described fastening zone and pierces into the roll body interior, described projection is provided with screw, and described screw runs through described projection and enters the inside of described roll body.
In preferred embodiment of the utility model, described roll central shaft adopts cast iron materials to make.
In preferred embodiment of the utility model, described roll body adopts structure steel material to make.
In preferred embodiment of the utility model, described work collars adopts Hardmetal materials to make.
In preferred embodiment of the utility model, described trip bolt number is 5 ~ 12.
In preferred embodiment of the utility model, the workspace thickness of described work collars is 1/3rd of roll body thickness.
The beneficial effects of the utility model are: the roll of being convenient to change that the utility model discloses, and flexible structure, working lining can change, and does not affect 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 utility model roll one preferred embodiment of being convenient to change;
The mark of each parts is as follows 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 utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the utility model embodiment comprises:
A kind of roll of being convenient to change, comprise: roll central shaft 1 and the roll body 2 that is arranged on the described roll central shaft 1, described roll body 2 one ends are provided with a plurality of grooves 3, described roll central shaft 1 is provided with the projection 4 that a plurality of and described groove 3 matches, described roll body 2 outsides are provided with the work collars, described work collars comprises the fastening zone 6 at workspace 5 and two ends, described fastening zone 6 thickness are less than workspace 5 thickness, described fastening zone 6 is provided with trip bolt 7, described trip bolt 7 runs through described fastening zone 6 and pierces into roll body 2 inside, described projection 4 is provided with screw 8, and described screw 8 runs through described projection 4 and enters the inside of described roll body 2.
After described work collars uses through long-term, certain damage is arranged, can disassemble, deliver to manufacturer's maintenance, change simultaneously new work collars, continue to use, can not incur loss through delay the manufacturing schedule of enterprise, flexible.
Described roll central shaft 1 adopts cast iron materials to make.
Described roll body 2 adopts structure steel material to make.
Described work collars adopts Hardmetal materials to make.
Described roll central shaft 1, roll body 2 and work collars adopt different materials, and than the roll of integral type, manufacturing cost is lower.
Described trip bolt 7 numbers are 5 ~ 12, so that work collars and described roll body 2 strong bonded are together.
The roll of being convenient to change that the utility model discloses, flexible structure, working lining can change, and does not affect manufacturing schedule, and each several part adopts different materials, and manufacturing cost is little.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; 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 utility model.
