Abstract
The utility model discloses a roller press and a self-synchronization abrasion roller of a high-voltage roller press, relating to a roller of the roller press (the high-voltage roller press). The roller press comprises a roller body; post nails are uniformly distributed on the roller face of the roller body by using the center of the roller face as a center within a range of 1/3-3/4 of a total width of the roller face; and textures are uniformly arranged on the rest part of the roller face in a bead weld manner. With the adoption of the roller press provided by the utility model, the roller keeps the original geometrical shape in an abrasion process; the operation rate of the roller press can be improved; and the maintenance cost of the roller can be reduced.
Description
Technical field
The utility model relates to a kind of roll squeezer (high-pressure roller mill) roller, is applicable to the industries such as building materials, metallurgy, mine and chemical industry roll squeezer, high-pressure roller mill.
Background technology
Roller of rolling machine is generally cylindrical, forms closed chamber with striker plate, and material is discharged from roll gap after a pair of roller extruding of relatively running.Roller suffered stress in the process that material is pushed successively decreases from the middle to both ends gradually, and the wearing and tearing of roller also just reduce from the middle to both ends gradually, thus the thick shape in thin two ends in the middle of forming.In case the wearing and tearing of roller mid portion are larger, roller just need be safeguarded or be scrapped.Therefore, the actual abrasion condition that depends on the roll surface mid portion of the life-span of roller.In the actual motion, normal conditions are that roller often causes reprocessing of whole roller because of the wearing and tearing of mid portion or scraps, and have increased the maintenance cost of roll squeezer, have reduced the operation ratio of equipment.If can guarantee that the roller degrees of wear middle and two ends are basically identical, then this situation will be improved.
Chinese patent CN201120334319.X has announced a kind of roll squeezer hard alloy stud roll surface, comprise roll surface and large stud, described large stud is located on the roll surface, on roll surface, also be provided with little stud, described little stud is around large stud setting, and appearing of little stud highly is lower than the height of appearing of large stud, and described roll surface is made by high strength steel, and described large stud, little stud are made by carbide alloy.
Chinese patent CN2201020587636.8 has announced a kind of roll surface for resurfacing welding of rolling press, and built-up welding has decorative pattern on roll surface, it is characterized in that: this decorative pattern is comprised of two groups of staggered in opposite directions parallel word lines.
Above-mentioned patent purpose is to increase the wearability of roll surface, and roll surface everywhere anti-wear performance is identical, still can't solve the use procedure middle roller and become middle thin two pluckings problems in stressed different situation.
The utility model content
The purpose of this utility model is: propose a kind of roll squeezer motor synchronizing wearing and tearing roller, can guarantee effectively that roller keeps original geometry in wear process, improve the roll squeezer operation ratio, reduce the maintenance cost of roller.
The utility model purpose realizes by following technical proposals:
A kind of roll squeezer and high-pressure roller mill motor synchronizing wearing and tearing roller comprises roll body, at described roll body roll surface centered by the roll surface center, uniform stud in roll surface overall width 1/3～3/4 scope, the remainder roll surface is the built-up welding decorative pattern equably.
As optimal way, described stud is that carbide alloy is made, and its hardness, intensity and wearability are greater than the high-abrasive material of built-up welding decorative pattern.
As optimal way, it is consistent that the built-up welding of described built-up welding decorative pattern height and stud are exposed the roll surface height.
As optimal way, described built-up welding decorative pattern lines be a word line, tiltedly shape line, netted line or ripple glaze.
The beneficial effects of the utility model: can guarantee effectively that roller roll surface in wear process keeps wearing and tearing everywhere synchronously, keep the original geometry of roller with this, be conducive to improve the roll squeezer operation ratio, reduce the roll squeezer maintenance cost.

The specific embodiment
Following non-limiting examples is used for explanation the utility model.
Embodiment 1:
As shown in Figure 1, a kind of roll squeezer and high-pressure roller mill motor synchronizing wearing and tearing roller comprises cylindrical metal roll body 1, at roll body 1 roll surface centered by the roll surface center, uniform stud 2 in roll surface overall width 1/3～3/4 scope, the remainder roll surface is built-up welding decorative pattern 3 equably.Stud 2 is made for carbide alloy, and its hardness, intensity and wearability are greater than the high-abrasive material of built-up welding decorative pattern 3.It is consistent that built-up welding height and the stud 2 of built-up welding decorative pattern 3 exposed the roll surface height.As optimal way, built-up welding decorative pattern 3 lines can be any lines, be preferably a word line, tiltedly shape line, netted line or ripple glaze, shown in Fig. 2 to 5.
Produce a kind of roll squeezer motor synchronizing wearing and tearing roller by above-mentioned principle, metal roll body 1 diameter 1400mm, roll surface overall width 400mm, roll surface middle width is the circular alloy stud 2 of the uniform diameter 16mm of 200mm part, and the remainder roll surface is with the high-abrasive material built-up welding decorative pattern 3 of the netted line of built-up welding equably.In running, because hardness, intensity and the wearability of roll body 1 mid portion stud 2 are greater than the high-abrasive material of adjacent both sides built-up welding decorative pattern 3, so roll body 1 mid portion stud 2 can keep synchronously wearing and tearing stressed with built-up welding decorative pattern 3 in greater than the situation at two ends, guarantee the original geometry of roller, thereby improve the roll squeezer operation ratio, reduce the maintenance cost of roller.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
