Abstract
The utility model discloses a novel tack-type roller surface structure, which comprises a roller sleeve and hard alloy tacks; and the hard alloy tacks (2) are fixed in the tack holes formed on the outer surface of a roller sleeve (1) in staggered arrangement through an adhesive (3). The utility model has the characteristics of high rigidity, strong abrasion resistance, long service life and the like. By the adoption of the tack-type roller of a roller press, the friction force between the roller surface and the material is increased, the material meshing performance of the roller surface is remarkably improved, the grinding efficiency of the roller press is improved, and the maintenance cost of the roller surface is reduced; at the same time, compared with the present tack-type roller surface structure, the roller surface structure has the advantages that the hard alloy tacks are convenient to be replaced, so that the roller surface is effectively protected; the roller sleeve can be constantly used, so that the replacement period of the roller sleeve is greatly prolonged, and the service life of the roller surface is prolonged; and the maintenance is convenient, the maintenance time and the maintenance cost of the equipment are reduced, and the operation rate of the equipment is effectively improved.
Description
Technical field
The utility model relates to the roll-in milling equipment, is particularly useful for a kind of novel post nail formula roll surface structure of the efficient roll-in mill of the various brittle materials of industrial circle grinding such as metallurgy, mine, coal, chemical industry.
Background technology
At present, two compression rollers that rotate in opposite directions of roll-in mill produce huge extruding force material are pulverized under the hydraulic system effect.The roll surface life-span of compression roller is related to operation rate and maintenance cost.Between post nail that the post nail formula roll surface structure of tradition roll-in mill is adopted and the roll surface post hole is interference fit, the post nail weares and teares, fractureing is difficult to extract when the post hole, be unfavorable for the independent replacing of post nail and the sustainable use of roller shell, even have to whole roller shell is scrapped, increased the cycle and the expense of maintenance of equipment.
Summary of the invention
For solving the problem that prior art exists, the purpose of this utility model is to provide a kind of novel post nail formula roll surface structure.Have the hardness height, characteristics such as hard formation is dark, erosion resistance is strong, post nail is replaceable, long service life, can reduce the maintenance of equipment expense, reduce the maintenance of equipment time, effectively improve operation rate.
For realizing aforesaid goal of the invention, the utility model adopts technical scheme as described below:
Described a kind of novel post nail formula roll surface structure comprises: roller shell, hard alloy columnar nail, described hard alloy columnar nail are fixed in the roller shell outer surface by the high strength bonding agent and are staggered in the post nail hole that is provided with.
Described a kind of novel post nail formula roll surface structure, the post nail hole of roller shell outer surface is positioned at the depression that the roller shell cross section is the U flute profile.
Described a kind of novel post nail formula roll surface structure, the hard alloy columnar nail is cylindrical, and the post nail cooperates with the post nail interporal lacuna of roller shell outer surface.
Described a kind of novel post nail formula roll surface structure, hard alloy columnar screw top face is higher than the outer of roller shell.
Owing to adopt aforesaid technical scheme, the utlity model has superiority as described below:
The work roll surface of this a kind of novel post nail formula roll surface structure has characteristics such as hardness height, erosion resistance are strong, long service life.The post of roll-in mill is followed closely the formula roll surface, has increased the frictional force of roll surface and storeroom, and the performance of roll surface interlock material is significantly improved, and has improved the mill efficiency of roll-in mill, has reduced the roll surface maintenance cost.Simultaneously; this roll surface structure is than present post nail formula roll surface structure; make the post nail be convenient to change; roll surface is effectively protected, and roller shell can continue to use, and the replacement cycle of roller shell is prolonged greatly; prolonged the life-span; and easy to maintenance, reduced maintenance time and cost of equipment maintenance, effectively improved operation rate.

Fig. 3 is that the A-A of Fig. 2 is to profile;
Among the figure: the 1-roller shell; 2-hard alloy columnar nail; The 3-bonding agent;
The specific embodiment
As shown in Figure 1, 2, 3: this a kind of novel post nail formula roll surface structure comprises: roller shell, hard alloy columnar nail, described hard alloy columnar nail (2) are fixed in roller shell (1) the outer surface post that is provided with that is staggered by bonding agent (3) to be followed closely in the hole.The post nail hole of described roller shell (1) outer surface is positioned at the depression that the roller shell cross section is the U flute profile.Described alloy column nail (2) is cylindrical, and the hard alloy columnar nail cooperates with the post nail interporal lacuna of roller shell (1) outer surface.Described hard alloy columnar nail (2) end face is higher than the outer of roller shell (1) outer surface.
During making, roller shell (1) adopts superior alloy steel, carries out special thermal treatment in the process; The post nail (2) that roller shell is inlayed adopts the high-strength wearable Hardmetal materials; Post nail is implanted in the roller shell post hole with matched in clearance, with a kind of high-strength adhesive (3) the two strong bonded is integral, and this bonding agent can lose cementability and makes the replacing easily of post nail again in 180-200 ℃.Because roller shell (1) adopts superior alloy steel in such scheme, the roller shell surface hard formation hardness after the process special thermal treatment is very high, hard formation is very dark, has improved the roll surface erosion resistance of comminuting matter under high pressure; High-pressure anti-wear hard alloy columnar nail (2) is with the densely covered roller shell surface of the form of being staggered; Grind novel post nail formula roll surface by the roll-in that roller shell and high-pressure anti-wear hard alloy columnar nail are formed, during comminuting matter, be full of material between the post nail and form spontaneous formula backing strap, storeroom is pulverized mutually, avoid roll surface directly to contact material and bear sharp wear, prevent that bulk materials from directly impacting roll surface, and bear material and be parallel to the strong motion wearing and tearing of roll surface, abrasion, wearing and tearing mainly occur in the very strong high-pressure anti-wear alloy column of erosion resistance and nail on, the roll surface working life is increased substantially, can effectively guarantee operation rate.
Simultaneously, after post nail damages, needing to change, can be heated and be fit to temperature and make bonding agent lose viscosity, is matched in clearance and post nail itself adopts, is easy to it is extracted and be replaced with new post nail, and roller shell then can continue use.In addition, because the maintenance of post nail is convenient, the height of post nail is easy to remain on level comparatively uniformly, and roll surface also obtains protection to a certain degree, thereby the life-span of roll surface is able to very big prolongation.
