Abstract

The utility model discloses a roller, including the roller body, roller body upper end is equipped with the shaft shoulder, the upper end of the shaft shoulder is provided with roller body linkage segment, the axis body lower extreme is equipped with integrated into one piece's roller body construction section, its characterized in that the roller body comprises with inside roller core the roller shell of outside, for two body structures, the roller shell with the shop bolt becomes integrative through the interference link pack for the roller core. The utility model has the advantages of reasonable design, the roller body is two body structures, and the roller shell is changed conveniently, and the roller core can reuse to practiced thrift the cost of roller core, the roller shell is alumina ceramics and compound the forming of unlimited two chill section bar matter centrifugation of nickel -chromium key spheroidal graphite, has improved the wear resistance of roller shell, has prolonged life, and the processing difficult problem of roller shell hole high accuracy has been solved to the high tenacity simultaneously.

Description

A kind of roll

Technical field

The utility model relates to a kind of metal machining field, particularly relates to a kind of roll.

Background technology

Roll is the key spare parts of milling train, also be maximum consumption product, 5 one 15% rolls that its expense accounts for steel rolling Cheng Mu consume maximum parts in producing as casting, its life-span and quality are the most direct factors affecting production rate and quality, the working lining of the mainly body of roll top layer certain depth of roll consumption, the thickest 100mm that is no more than, work roll cooling is to during condemning limit or when there is larger defect, roll is scrapped with regard to entirety, cause larger waste, surface overlaying breaker roll is often adopted to carry out repairing and reusing in the market in order to improve utilization ratio, but because barrel diameter is little, output grooved less than normal, Bead weld repair acquires a certain degree of difficulty, and kind method complex process, repair inconvenience, and repair after effect bad, affect its life-span and product quality, therefore market is badly in need of a kind of, become wood low, result of use is good, can the roll be made up of roller core and roller shell of split, but only need new roller shell be assembled on old roller core after roller shell wearing and tearing, just can be combined into new roller to use.

Utility model content

For problems of the prior art, it is simple that the purpose of this utility model is to provide a kind of structure, and roller body is two body structures, and roller shell is changed convenient, a kind of roll that roller core can reuse.

The utility model is realized by the following technical programs: described a kind of roll, comprise roller body, described roller body upper end is provided with the shaft shoulder, the upper end of the described shaft shoulder is provided with roller body linkage section, described roller body lower end is provided with integrated roller body construction section, it is characterized in that described roller body is made up of with inner roller core the roller shell of outside, be two body structures, described roller shell and described roller core shop bolt are linked and packed integral by interference.

Described a kind of roll, is characterized in that: on the outer wall of described roller body linkage section, interval arranges multiple tooth bar.

Described a kind of roll, is characterized in that: described roller body construction section is pancake installing plate, and roller body construction section is provided with installing hole, locating slot from top to bottom successively, and the left and right sidewall of roller body construction section is symmetrically arranged with cutting.

Compared with prior art, the beneficial effects of the utility model are: reasonable in design, roller body is two body structures, roller shell is changed convenient, and roller core can reuse, thus has saved the cost of roller core, roller shell is that aluminium oxide ceramics and nickel chromium triangle key spheroidal graphite indefinite chill two section bar matter centrifugal compound form, improve the anti-wear performance of roller shell, extend service life, high tenacity solves the high-precision processing difficult problem of roller shell endoporus simultaneously.

Accompanying drawing explanation

Fig. 1 is the structural representation of this aspect;

In figure: the 1-shaft shoulder, 2-roller body linkage section, 3-roller body construction section, 4-roller shell, 5-roller core, 6-shop bolt, 7-tooth bar, 8-installing hole, 9-locating slot, 10-cutting.

Detailed description of the invention

Below in conjunction with Figure of description, the utility model is described in further detail, and provides detailed description of the invention.

As shown in Figure 1, a kind of roll of the utility model, comprise roller body, roller body upper end is provided with the shaft shoulder 1, the upper end of the shaft shoulder 1 is provided with roller body linkage section 2, roller body lower end is provided with integrated roller body construction section 3, in order to roller shell is changed conveniently, roller core can reuse, roller body is that two body structures are made up of with inner roller core 5 roller shell 4 of outside, roller shell 4 and roller core 5 shop bolt 6 are linked and packed integral by interference, in order to improve the anti-wear performance of roller shell, increase the service life, solve the high-precision processing difficult problem of roller shell endoporus, preferred roller shell 4 adopts aluminium oxide ceramics and nickel chromium triangle key spheroidal graphite two section bar matter centrifugal compound to form, shape is the circle cover of hollow two-layer material, in use stablize to make roll, on the outer wall of preferred roller body linkage section 2, interval arranges multiple tooth bar 7, roller body construction section 3 is pancake installing plate, roller body construction section 3 is provided with installing hole 8 from top to bottom successively, locating slot 9, the left and right sidewall of roller body construction section 3 is symmetrical arranged cutting 10.

In use, when roller shell 4 reaches condemning limit or occur larger defect, only need change roller shell 4, roller core 5 can reuse, thus has saved the cost of roller core, improves the service life of roll, reduces production cost.
