Abstract
The utility model discloses an emery cloth wheel, which comprises an attached board, an emery cloth layer and an adhesive layer. The attached board is provided with circular steps, the emery cloth layer is formed by convoluting counterclockwise and overlaying a plurality of layers of emery cloth, the grinding surface of the emery cloth faces outwards; one end of the emery cloth is connected with the adhesive layer and the attached board in sequence, the other end of the emery cloth is a free end which consists of a cylindrical surface, and the emery cloth is made of corundum grit or silicon carbide grit. Since the hardness of the corundum is HV1800-2200, higher than the surface hardness of the steel rail, and the hardness of the silicon carbide is HV2840-3300, higher than the surface hardness of the steel rail, the surface of the steel rail brushed by the emery cloth wheel has the bright metal luster. In addition, the shape of the emery cloth is fundamentally identical to the shape of the surface of the steel rail and the emery cloth is soft, the geometry of the steel rail can not be changed during friction. Moreover, the utility model can overcome the defects of the prior art that the steel rail is black after being brushed by the steel wire wheel, and less than 80 percent of the steel rail has the metal luster.
Description
Technical field
The utility model relates to a kind of grinding utensil, especially relates to a kind of emery cloth wheel that is exclusively used in rail rust removal.
Background technology
The emery cloth wheel has purposes very widely, and itself and electronic, pneumatic milling tools combine, and are commonly used to the surface of multiple rail is handled.
Existing rail rust removal mode often adopt wire brush to the upper and lower rail level and the track end face of track clean with water, since rail be the 65Mn steel and be in normalized condition, its hardness is about about HV372, the wire of wire brush directly is 1-1.2mm, and its hardness is HV425-514.At wire brush rail is carried out in the rust cleaning process, although the cleaning with water of repeated multiple times, but still can't reach rail surface, rust cleaning back presents metallic luster more than 80% requirement.
The utility model content
The purpose of this utility model provides a kind of rail rust removal emery cloth of being made by corundum or carborundum cloth small pieces wheel that adopts definite shape, adopt wire wheel to clean rail with water thereby remedied prior art, rail presents corvinus and does not reach the defective that presents the metallic luster state more than 80%.
The technical scheme that its technical problem that solves the utility model adopts is:
The emery cloth wheel comprises attached plate, emery cloth layer, adhesive linkage; Have the annular step on the attached plate, the emery cloth layer is to curl up stacked forming counterclockwise by the multilayer emery cloth, and the abradant surface of emery cloth toward the outer side; One end of emery cloth connects adhesive linkage, attached plate successively, and the other end is a free end, and all emery cloth free ends constitute a face of cylinder, and emery cloth is made by corundum or carborundum sand grains.
Described attached plate is a triangular shape.
Described attached plate is cylindric.
Described emery cloth serves as that axle curls up with the central axis of attached plate.
Described emery cloth is rectangle.
Described emery cloth is complementary with the rail convex surface on one side.
Described attached plate is provided with locating hole.
The beneficial effects of the utility model are: compare with wire brush, corundum of the present utility model or carborundum cloth wheel raceway surface is polished, during grinding operation, because the hardness of corundum is HV1800-2200, and the hardness of carborundum is HV2810-3300, the hardness of two kinds of sand grains all is higher than the case hardness of rail far away, so can make the surface of the rail of being brushed present metallic luster.In addition, the shape of emery cloth and emery cloth consistent with the surface state of rail is soft, is the geometry that can not change rail like this when friction.Emery cloth is under the resistance and itself action of centrifugal force of raceway surface, its free end spreads out each other against its direction of rotation, the emery cloth wheel is the face contact with contacting of rail surface, and because of the gap between the emery cloth, make that the contact stress on emery cloth and rail surface is little, so both reached the effect of polishing, also prevented excessive wear effectively the rail base material.Emery cloth wheel of the present utility model is when polishing the rail with curved surface, because of the emery cloth on it can spread out when working, when contacting with the rail surface, emery cloth can be along the rail surface move towards to take place certain deformation, emery cloth can fully be fitted with curved surface like this, thereby improved the operating efficiency of polishing, between emery cloth layer and attached plate, be provided with tack coat again, so also be convenient to realize large batch of production.

The specific embodiment
Please refer to Fig. 1, Fig. 2, Fig. 5 and Fig. 6, the emery cloth of present embodiment wheel 4 mainly is made of one deck emery cloth layer 1, two attached plates 2, one deck glue 3, the annular step 21 that has triangular shape on the columned attached plate 2, this step 21 is used to set up glue 3 and emery cloth layer 1, emery cloth layer 1 is to curl up stacked forming counterclockwise by multilayer corundum cloth or carborundum cloth 11, wherein emery cloth is made by corundum sand grains or carborundum sand grains, and the abradant surface of emery cloth toward the outer side; One end of emery cloth connects glue 3, attached plate 2 successively, the other end is free end and constitutes a face of cylinder, the stiff end that emery cloth is connected with glue 3 is together adjacent each other, and serves as that axle curls up with the central axis of attached plate 2, can make more satisfactory emery cloth wheel 4 like this.
Please refer to Fig. 3, the utility model can select for use four limits to be the rectangular corundum or the carborundum cloth 11 of straight flange.
The utility model please refer to Fig. 4, one side also can be selected the corundum or the carborundum cloth 11 of the track mating surface 12 that having in four limits match with orbital plane for use.
Be convenient to install and use,, have several locating holes 22 on the attached plate 2 in corresponding position.
The foregoing description adopts glue as adhesive linkage; certainly also can use other that other material of binding function is all arranged; more than by the specific embodiment principle of the present invention is described; obviously; those of ordinary skill in the art can be on the basis of above instruction, and the present invention is done various improvement, is out of shape, is equal to and replace and do not break away from protection scope of the present invention.
