Abstract
The utility model relates to a steel-base self-sharpening type metal cold and hot cutting circular saw blade, which belongs to the technical field of steel processing tool. The utility model provides a steel-base metal cold and hot cutting circular saw blade which has long cutting life and good cutting effect, while reducing the processing waste and improving the utilization rate of raw material. The saw blade, adopts a disk which consists of an alloyed steel substrate and a grinding wheel arranged at the periphery. The substrate and the grinding wheel are sintered and connected as a whole, wherein a center hole is arranged at the center of the substrate, a plurality of driving holes are arranged at the periphery except the center hole; a beading and a connecting groove are arranged at the periphery of the substrate, the beading and the connecting groove are connected and overlapped with a concave and a convex on the grinding wheel, and the grinding wheel at the connection part covers on the surface of the beading of the steel base. After the lathe processing of the steel substrate of the metal cold and hot cutting circular saw blade is completed, the steel substrate and grinding wheel forming materials are laid out in the mould according to the set size and shape, and then sintered. The saw blade has the advantages of long cutting life, good cutting effect and integration the advantages of two prior cutters as a whole; meanwhile, the processing waste is reduced, and the utilization rate of raw material is improved.
Description
Technical field
The utility model relates to a kind of steel alloy and makes the cold and hot metal cutting circular saw blade that matrix, emery wheel are made cutting edge, belongs to the technical field of tools of working steel products.
Background technology
At present, the employed metal material cast-cutting saw of every profession and trade mainly contains metal circular saw and abrasive cutoff saw saw blade.Along with industrial development, this cutting blade of two types has all formed various variety type, and it is ripe that production technology also is tending towards.Wherein, the cutting life-span of metal circular saw is apparently higher than cutoff wheel, and recyclable utilization after scrapping, but the metal circular saw cutting mouth is coarse, and is jagged; And cutoff wheel is applicable to high strength, heavy load operation, and cutting mouth is neat, no burr, but the cutoff wheel loss is fast, and production cost is big, and thick than the metal saw blade with the cutoff wheel of diameter, and otch is big, and waste is serious.In view of above analysis, the pluses and minuses of two kinds of cutters can be carried out complementation, research and development novel metal cutting tool.
Summary of the invention
The purpose of this utility model is the pluses and minuses of existing two kinds of cutting tools are carried out complementation, provide a kind of life-span steel alloy long, good cutting effect that cuts to make the base steel self-sharpening cold and hot metal cutting circular saw blade that matrix, emery wheel are made cutting edge, simultaneously, can reduce processing waste material, improve raw material availability.
Problem described in the utility model realizes with following technical scheme:
A kind of base steel self-sharpening cold and hot metal cutting circular saw blade, it is a disc, described disc is made up of the matrix of alloy steel and the emery wheel of outer rim, sintering connects as one between matrix and emery wheel, and wherein, there is centre bore at the matrix center, the border is provided with driving hole beyond the centre bore, the matrix excircle is provided with convex shoulder and is connected groove, this convex shoulder be connected groove and be connected with concavo-convex overlapping on the emery wheel, junction emery wheel bag is attached to base steel convex shoulder surface.
Above-mentioned base steel self-sharpening cold and hot metal cutting circular saw blade, the thickness of described emery wheel outer rim is greater than matrix thickness 1-4mm.
Above-mentioned base steel self-sharpening cold and hot metal cutting circular saw blade, described emery wheel cutting edge are identical slab construction of thickness or bilateral symmetry sideshake structure.
Above-mentioned base steel self-sharpening cold and hot metal cutting circular saw blade, the connection groove on the described base steel excircle convex shoulder divides groove abdomen and groove neck two parts, with the sintering bonding strength between further reinforcement matrix and the emery wheel.
Above-mentioned base steel self-sharpening cold and hot metal cutting circular saw blade, described driving hole is evenly distributed.
After the steel substrate turning of the utility model cold and hot metal cutting circular saw blade machines, steel substrate and abrasive wheel forming material are arranged by the size and dimension of setting in mould, carry out sintering, behind the sintering base steel and the further shaping of emery wheel are processed, to guarantee the physical dimension and the form and position tolerance of saw blade.Its cutting tip is made up of abrasive material, bond, reinforcing mat, and when cutting workpiece, abrasive material is finished the cutting task, bond plays the effect that connects and clasp, abrasive material constantly comes off along with self wearing and tearing, passivation, exposes the sharpness that new corner angle keep abrasive material, has good self-sharpening.This saw blade has reduced processing waste material along with the carrying out oneself of cutting diminishes gradually, has improved utilization ratio of raw materials.The utility model integrates the advantage of existing two kinds of cutting tools, and the cutting life-span is long, effective.
