Description
Technical field
The utility model relates to a kind of roll, and particularly a kind of assembly roller, for the pre-planishing roll of high line.
Background technology
Along with the quickening of rhythm of production and the development of steel rolling technology, with the higher output of same equipment acquisition, larger economic benefit, it is the pursuit of every steel rolling production-line, tradition roll wears no resistance because of it, make to change hole, roll change is frequent, on average taken about 8%-10% of production time, special particularly evident on the continuity milling train of high efficiency, high yield, seriously restricted production and product quality.
There is larger defect in the existing roll manufacturing and designing, be mainly reflected in: molding roller is when rolling differential profiles, and the roll that need to change different model solves the problem of section bar horizontal width, and exchonge step is loaded down with trivial details, can not guarantee the installation accuracy of roll, had a strong impact on the quality of rolling simultaneously.
Roll is the main consumable part on milling train, and at present, common roll adopts integrally casting, and after roll surface wearing, whole roll is scrapped, and service life is short, has caused great waste, the whole inconvenience of manufacturing, and manufacturing process is complicated, and production cost is high.
Utility model content
The purpose of this utility model is to overcome above deficiency of the prior art, and a kind of simple in structure, good stability, long service life, assembly roller that job stability is high are provided.
The technical scheme that the utility model provides is:
A high speed steel roll collar assembly roller, is characterized in that, comprises positioning sleeve, high speed steel roll collar group, locking device and axle core, and the coaxial and opsition dependent relation of described positioning sleeve, high speed steel roll collar group, locking device three is screwedly mounted on axle core successively.
Described positioning sleeve is screwedly mounted on axle core, is positioned at axle core avris end.
Described high speed steel roll collar group comprises some high speed steel roll collars, some spacer sleeves and unloads power groove, and whole high speed steel roll collar group is stably positioned at the middle position of axle core by positioning sleeve.Described high speed steel roll collar group is by a plurality of high speed steel roll collars unit superimposed composition, and adjacent high speed steel roll collar adopts spacer sleeve to be separated by between unit, and the position that axle core coordinates with spacer sleeve is provided with unloads power groove.
Described locking device comprises clamping screw and lock sleeve, is positioned at the another side side of axle core; Lock sleeve is screwedly mounted on axle core, and clamping screw is fixed on axle core in lock sleeve, to guarantee that assembly roller is locked at axial direction.
The utility model product purpose: for the pre-planishing roll of high line.
Advantage of the present utility model and beneficial effect are as follows: due to composite (back-up) roll by collars, spacer sleeve, unload power groove, clamping screw, lock sleeve, axle core and form, structural design is simple, easy to assembly, job stability is high, has reduced production cost.Specifically, overall structure is simple, improved the application mode of the roll of integral type, take the mode of combination, indirectly reduced the process time of roll, the more important thing is to have facilitated the reparation of profiled part is changed, after roll surface wearing, the limitation that can avoid whole roll to scrap, and overcome the whole problems such as inconvenient of manufacturing.The utility model, without integral replacing, is saved processing cost.

The specific embodiment
Below in conjunction with accompanying drawing, describe most preferred embodiment of the present utility model in detail.
As shown in Figure 1, the present embodiment high speed steel roll collar assembly roller, comprises positioning sleeve 1, high speed steel roll collar group, locking device and axle core 7, and the coaxial and opsition dependent relation of described positioning sleeve 1, high speed steel roll collar group, locking device three is screwedly mounted on axle core 7 successively.
Obviously, described axle core 7 is transmission, the support components as whole roll.Described positioning sleeve 1 is screwedly mounted on axle core 7, is positioned at axle core 7 avris ends.Positioning sleeve 1 plays pair roller loop mapping and lateral protection.
Described high speed steel roll collar group comprises some high speed steel roll collars 2, some spacer sleeves 3 and unloads power groove 4, and whole high speed steel roll collar group is stably positioned at the middle position of axle core 7 by positioning sleeve (1).Described high speed steel roll collar group, by a plurality of high speed steel roll collars unit superimposed composition, adopts spacer sleeve 3 to be separated by between adjacent high speed steel roll collar unit, and the position that axle core 7 coordinates with spacer sleeve 3 is provided with unloads power groove 4.Whole high speed steel roll collar group is the working portion of roll, and it is arranged on the centre of axle core 7 after by positioning sleeve 1 heating, and 3 of spacer sleeves are wherein across adjacent high speed steel roll collar 2, for cushioning stress; The power of unloading groove 4 is wherein conducive to releasing heat stress, plays overload protection.Described locking device comprises clamping screw 5 and lock sleeve 6, is positioned at the another side side of axle core 7; Lock sleeve 6 is screwedly mounted on axle core 7, and clamping screw 5 is fixed on axle core 7 in lock sleeve 6, to guarantee that assembly roller is locked at axial direction.Function aspects, obviously clamping screw 5 is for axial locking; Lock sleeve 6 is conducive to the protection of collars side direction and has locking effect.
The present embodiment is simple in structure, takes the application mode of the integral type roll of roller shell and roller core interference combination.Thermal expansion stress when structural design has been considered roll work, the adhesion of needs between roller shell and mandrel while also meeting roll work.
