Abstract
The utility model discloses a special -shaped home roll of open ring rolls, install in the epaxial home roll cover of home roll including home roll axle and detachable, the home roll cover comprises the shaping section on upper portion and the annular groove of lower part, the external diameter of shaping section from top to bottom steadilys decrease in proper order, the annular groove sets up the direction section of convex structure and the changeover portion that the slope was arranged with the junction of shaping section. A dysmorphism ring piece that special -shaped home roll of open ring rolls can directly process out and take tapering area step to the significantly reduced work load of machine tooling has improved work efficiency, and home roll cover detachable installs in the home roll epaxially, and convenient to detach safeguards that in addition, the outside of home roll cover sets up abrasion -resistant alloy steel layer, improves its wear resistance greatly, and the life of extension home roll cover, easily realizes simple structure.
Description
Technical field
The utility model relates to a kind of open type ring rolls, particularly relates to a kind of special-shaped home roll of open type ring rolls.
Background technology
At present, home roll for the production of the open type ring rolls of ring is normally made up of home roll axle and the home roll cover be fixedly mounted on home roll axle, home roll cover is the sleeve of a square-section, it can only process straight tube shape ring, when needing the ring processing other shapes, normally on the basis of straight tube shape ring, mach method is adopted to reach the shape and size of needs, its workload is larger, and the home roll of existing open type ring rolls home roll cover very easily weares and teares, and home roll cover is fixedly connected with home roll axle, and it is very inconvenient to safeguard, thus, be badly in need of solving.
Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of special-shaped home roll of open type ring rolls, and with the problem that the workload solving the processing profiled ring of home roll adopting existing open type ring rolls is large, and existing home roll is easy to wear, safeguards the problem of inconvenience.
The purpose of this utility model is achieved through the following technical solutions:
A kind of special-shaped home roll of open type ring rolls, comprise home roll axle and dismountable home roll cover be installed on home roll axle, described home roll cover is made up of the profiled section on top and the annular groove of bottom, the external diameter of described profiled section from top to bottom successively decreases successively, the guide section that the junction of described annular groove and profiled section arranges arc-shaped structure and the changeover portion be in tilted layout.
As a kind of preferred version of the present utility model, described home roll cover is connected with home roll axle interference fit.
As a kind of preferred version of the present utility model, the outer setting of described home roll cover has antifriction alloy steel layer.
The beneficial effects of the utility model are, the special-shaped home roll of described a kind of open type ring rolls directly can process band tapering special-shaped ring with the level, thus greatly reduce mach workload, improve operating efficiency, and home roll cover is dismountablely installed on home roll axle, be convenient to demolition and maintenance, in addition, the outer setting antifriction alloy steel layer of home roll cover, improves its anti-wear performance greatly, extend the service life of home roll cover, structure is simple, be easy to realize.

Fig. 2 is the structural representation of the utility model home roll cover.
In figure:
1, home roll axle; 2, home roll cover; 21, profiled section; 22, annular groove; 23, guide section; 24, changeover portion; 25, antifriction alloy steel layer.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.Be understandable that, embodiment described herein only for explaining the utility model, but not to restriction of the present utility model.
Please refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the structural representation of the special-shaped home roll of a kind of open type of the utility model ring rolls; Fig. 2 is the structural representation of the utility model home roll cover.
In the present embodiment, a kind of special-shaped home roll of open type ring rolls, comprise home roll axle 1 and dismountable home roll cover 2 be installed on home roll axle 1, described home roll cover 2 is connected with home roll axle 1 interference fit, and the outer setting of home roll cover 2 has antifriction alloy steel layer 25, home roll cover 2 is made up of the profiled section 21 on top and the annular groove 22 of bottom, the external diameter of described profiled section 21 from top to bottom successively decreases successively, the guide section 23 that described annular groove 22 and the junction of profiled section 21 arrange arc-shaped structure and the changeover portion 24 be in tilted layout.
By adopting special-shaped home roll of the present utility model, directly can process band tapering special-shaped ring with the level, avoid the waste of machining process Raw, decrease mach workload simultaneously, improve production efficiency, reduce production cost, and the setting of guide section 23 and changeover portion 24, effectively can ensure the Forming Quality of product, in addition, home roll cover 2 is connected with home roll axle 1 interference fit, be convenient to demolition and maintenance, the setting of antifriction alloy steel layer, substantially increase the wearability of home roll cover 2, extend the service life of home roll cover 2, structure is simple, be easy to realize.
Above embodiment has just set forth general principle of the present utility model and characteristic; the utility model does not limit by above-described embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various change and change, and these changes and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
