Description
Technical field
The utility model relates to cut-off wheel, and especially global formation solidifies, is used for the resin abrasive cutting wheel of cutting metal material.
Background technology
Abrasive cut-off wheel commonly used on the engineering is to mix the back compacting with adhesive with diamond dust to form at present, and its shape mostly is the uniform disk of thickness, and center drilling is to be installed on the axle.During work, emery wheel is rotation at a high speed under the drive of axle, contacts with the metal works that is cut under pressure and violent friction, thereby reach the purpose of cutting, add man-hour, the rotation of emery wheel is main motion, and emery wheel is feed motion with relative translation between the workpiece.The range of work of emery wheel depends on its diameter, and working (machining) efficiency then depends on the speed of main motion.Obviously, the big more then range of work of grinding wheel diameter is big more, and the high more then working (machining) efficiency of main motion speed is high more.When cutting processing, the rotation of emery wheel makes self is bearing centrifugal force, emery wheel and the friction that is cut between the metal works not only make emery wheel be subjected to distortion power, the periphery of emery wheel is risen because of the frictional heat temperature, feed motion is when constantly cutting metal, thereby two end faces that also make emery wheel constantly and be cut that metal works takes place that friction has aggravated the emery wheel whole outer surface and then be the temperature rise phenomenon of emery wheel integral body.The emery wheel of traditional structure only depends on the contend with effect of centrifugal force and distortion power of the cohesive force of common organic resin, for requiring the cutting large size metal (promptly to require grinding wheel diameter big, more than 1200mm) and wish that the raising working (machining) efficiency (promptly requires emery wheel rotary speed height, week, end line speed was more than 100m/s) occasion, because the centrifugal force and the distortion power that are born during the work of large high-speed emery wheel are all very big, and periphery and end face temperature rise all are exceedingly fast, if still adopt traditional structure, when cutting, rotate the powerful centrifugal force that is produced at a high speed, the rise cohesive force that caused of huge distortion power that violent friction is produced and temperature descends under the acting in conjunction of these factors, emery wheel hardness is reduced, the wearing and tearing aggravation is more seriously because cohesive force may cause emery wheel disintegration explosion inadequately.Because traditional grinding wheel structure is difficult to take into account the requirement in intensity, efficient, life-span in the occasion of large high-speed, therefore the size and the rotary speed of domestic emery wheel are very limited all the time, thereby have restricted the expansion of its range of work and the raising of working (machining) efficiency.
The utility model content
The utility model discloses a kind of cut-off wheel, especially global formation solidifies, is used for the resin abrasive cutting wheel of cutting metal material, in order to overcome the deficiencies in the prior art, solves the use problem of emery wheel in the occasion that the high-speed process requirements of large scale is arranged.
The utility model adopts following technical scheme to achieve the goal:
Resin abrasive cutting wheel, formed by the whole compression moulding of abrasive particle and organic resin, be disc and circular hole is opened at the center, abrasive particle is uniformly distributed in the organic resin, be uniform-distribution with 1～5 layer vertically by the fiberglass braided screen cloth that forms in organic resin, glass fiber mesh is parallel to both ends of the surface.
Described resin abrasive cutting wheel is uniform-distribution with staple glass fiber in organic resin, length is below 8mm, and addition is 10%～15% of abrasive particle and an organic resin weight sum.
Described resin abrasive cutting wheel, abrasive particle expose on two end faces of emery wheel.
Described resin abrasive cutting wheel, overall diameter is between 1200mm～1600mm.
Described resin abrasive cutting wheel, abrasive particle is selected any one the particle in brown corundum, white fused alumina, pink fused alumina, fused alumina zirconia, Pr-Nb fused alumina, black silicon carbide, green silicon carbide, boron carbide, boron nitride, diamond dust and the diamond for use, and granular size is at 1000 μ m～1250 μ m; Organic resin is selected phenolic resins for use.
Adopt the technical solution of the utility model, owing to having added high-intensity glass fiber mesh and short glass fiber as supporting material when emery wheel compression moulding, what binding agent was selected for use is high-intensity phenolic resins, has strengthened the intrinsic strength of emery wheel.During compression moulding, use has the big press of hot-press arrangement and implements, adopt temperature in 150 ℃～170 ℃, pressure HTHP compression moulding technology at 1250MPa～1350MPa, improve the compact density 30%～50% of emery wheel, thereby make emery wheel intensity increase by 30%～50%, durability prolongs 30%～50%, has satisfied in large scale and has processed under the occasion requirement to emery wheel at a high speed.
The abrasive particle of emery wheel exposes on two end faces of emery wheel, can reduce the frictional resistance of emery wheel when cutting, improves the grinding efficiency at emery wheel two ends, more can adapt to large scale, the cutting of large tracts of land workpiece material.

The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, present embodiment has provided detailed embodiment and process being to implement under the prerequisite with the technical solution of the present invention, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, resin abrasive cutting wheel, be disc and circular hole is opened at the center, the overall diameter of emery wheel is 1600mm, form by abrasive particle 1 and organic resin 2 whole compression mouldings, it is the fused alumina zirconia of 16# that abrasive particle 1 is selected granularity for use, and promptly granular size is at 1000 μ m～1250 μ m, is uniformly distributed in the organic resin 2 and exposes on two end faces of emery wheel.
The high-strength phenolic resin that organic resin 2 selects for use German Berlet company to produce is distributing 1 layer vertically by the fiberglass braided screen cloth that forms 3 in organic resin 2, glass fiber mesh is parallel to both ends of the surface; Be uniform-distribution with staple glass fiber 4 in organic resin, length is below 8mm, and addition is 15% of abrasive particle and an organic resin weight sum.
Resin abrasive cutting wheel adopts temperature in 150 ℃～170 ℃, the pressure HTHP compression moulding technology at 1250MPa～1350MPa when compression moulding, and method for making is as follows:
