Abstract
The utility model discloses a festival massif high-speed railway rail grinding wheel, including metal matrix and two abrasive material pieces, metal matrix positive center department is equipped with the internal thread, two abrasive material pieces are concentric circles with the metal matrix, the abrasive material piece includes a plurality of abrasive material unit and all is festival massif, the abrasive material unit of two abrasive material pieces is outwards staggered each other in proper order and arranges and thickness all is completely unanimous, the material of two abrasive material pieces is the diamond and height in the vertical direction is completely unanimous; the diamond grinding material is not easy to abrade, long in service cycle and free of frequent replacement, low in use cost, simple and convenient to operate, good in grinding effect, high in efficiency, less in dust, small in environmental pollution, small in potential safety and health hazards, good in heat dissipation effect and small in grinding material damage.
Description
Technical Field
The utility model belongs to the metal grinding field, in particular to cubic high-speed railway rail grinding wheel of festival that long service life, effectual.
Background
The emery wheel need be used in the grinding of high-speed railway rail, just at present, current emery wheel all adopts the corundum of zirconium material to be the abrasive material, and the abrasive material all is a monoblock, a monoblock abrasive material emery wheel of this kind of corundum of zirconium material can satisfy certain user demand, but also there is great defect, the easy wearing and tearing of corundum of zirconium damage life weak point, need frequently to change, use cost is high, the troublesome poeration is inconvenient, the grinding effect is poor inefficiency, the dust is big to environmental pollution, there is great safe and healthy hidden danger, overall structure heat dissipation is poor simultaneously, it is big to the abrasive material damage easily to gather heat, further reduce life.
The to-be-solved technical problem of the utility model is to provide a life cycle length need not frequent change, use cost low operation is convenient, grinding effect is efficient, the dust is few environmental pollution little, the potential safety health hazard is little, the radiating effect is good to the cubic high-speed railway rail grinding wheel of festival that the abrasive material damage is little.
SUMMERY OF THE UTILITY MODEL
For solving above-mentioned prior art easy wearing and tearing damage life weak point, need frequently to change use cost height, inconvenient grinding effect difference inefficiency of troublesome poeration, dust exist great safe and healthy hidden danger, the poor easy gather heat of heat dissipation to the big scheduling problem of abrasive material damage to environmental pollution greatly, the utility model discloses a following technical scheme:
the utility model provides a festival massif high-speed railway rail grinding wheel, including metal matrix and two abrasive material pieces, metal matrix positive center department is equipped with the internal thread, two abrasive material pieces are the concentric circles with metal matrix, the abrasive material piece includes a plurality of abrasive material unit and all is festival massif, the abrasive material unit of two abrasive material pieces outwards staggers each other in proper order and arranges and thickness all is identical completely, the material of two abrasive material pieces is the diamond and highly identical on the vertical direction.
As an improvement, the material of the abrasive material block is a metal bond diamond.
As a further improvement, the material of the abrasive material block is ceramic bond diamond.
The beneficial effects of the utility model reside in that: the diamond grinding material is not easy to abrade, long in service cycle and free of frequent replacement, low in use cost, simple and convenient to operate, good in grinding effect, high in efficiency, less in dust, small in environmental pollution, small in potential safety and health hazards, good in heat dissipation effect and small in grinding material damage.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, the nodal-block-shaped grinding wheel for the high-speed rail comprises a metal base and two grinding blocks, wherein an internal thread is arranged in the center of the metal base, the two grinding blocks and the metal base are concentric circles, each grinding block comprises a plurality of grinding units and is in a nodal shape, the grinding units of the two grinding blocks are sequentially arranged outwards in a staggered mode, the thicknesses of the grinding units are completely consistent, the two grinding blocks are made of diamonds, and the heights of the two grinding blocks in the vertical direction are completely consistent.
The abrasive block is made of metal bond diamond or ceramic bond diamond, the metal bond diamond is high in toughness and good in wear resistance, the ceramic bond diamond is good in sharpness and high in grinding speed, the abrasive block has the advantages and can be selected according to actual needs, and the abrasive block is better in using effect than common zirconium corundum.
The beneficial effects of the utility model reside in that: the diamond grinding material is not easy to abrade, long in service cycle and free of frequent replacement, low in use cost, simple and convenient to operate, good in grinding effect, high in efficiency, less in dust, small in environmental pollution, small in potential safety and health hazards, good in heat dissipation effect and small in grinding material damage.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
