Description
Technical field
The present invention relates to a kind of sawing machine of sawtooth or cutter of saw cutting device of having, especially relate to a kind of sintered carbide circular saw that is mainly used in cutting steel, steel plate, iron and steel.
Background technology
The instrument of existing cutting steel is grinding wheels, when cutting with grinding wheel, has shortcomings such as noise is big, dust is big, cutting effect is coarse, efficient is low.
Notification number is used for hot-metal sawing machine and cold sawing machine to steel rolling mill's rolled piece sawing for the utility model patent of CN2213599 provides a kind of metal circular saw of cutting.This saw blade is a carbide bit such as resistance welded tungsten cobalt titanium on the teeth groove of matrix, forms the carbide alloy sawtooth behind sharpening.
Notification number has rosette for the utility model patent of CN2737493 provides a kind of cutting saw blade, axis hole is arranged respectively in this disk and through hole is installed, and disk side ring row sawtooth, disk are divided by inner circular part and the outer ring portion welding constitutes.Wherein inner circular part divides the lower ordinary steel material of employing price to make, and has saved material cost.Outer ring portion also can be welded to form by the polylith steel, to reduce processing waste material.
Notification number provides a kind of steel parting tool for the utility model patent of CN2928342, particularly a kind of energy-saving metal cold hot cut circular saw blade that is used for large-scale circular sawing machine.Its blade bodies of this saw blade is a disk that centre bore is arranged, and the disk outer peripheral edges have sawtooth, and two sides of disk are processed with the attenuate cannelure with center of circle symmetry.Compare with the common metal cold hot cut circular saw blade, because the sideshake that these saw blade two sides have the attenuate cannelure to constitute, make saw blade reduce the chance that contacts with the workpiece section, reduced the frictional force of workpiece to saw blade, make main motor working current can reduce by 30%～40%, peak point current can reduce by 50%, therefore can allow saw suitably to improve feed speed, improve Rolling Production efficient, can save the sawing energy consumption simultaneously and reach 25%～30%.
Notification number is for the utility model patent of CN201009299 provides a kind of riveted joint tooth saw blade, comprises circular saw body, and saw body outer ledge evenly has rivet hole, and the cooperation of gear piece by rivet hole and rivet is fixed on one's body the saw.Cutting teeth is arranged on the gear piece, and cutting teeth one lateral edges is provided with side edge, and forward position, cutting teeth top is provided with the top sword, also is provided with at least two on the gear piece and is used for the rivet hole that rivet connects.Gear piece is provided with limit material tooth, and limit material tooth is positioned at before the cutting teeth top sword that height is provided with a little less than forward position, cutting teeth top.
Notification number provides a kind of steel fixed ruler cutting cold and hot metal cutting circular saw blade for the utility model patent of CN201020567, the blade bodies of this saw blade is a big and thin disk, be distributed with sawtooth on the excircle of blade bodies, the center is porose, centre bore has driving hole outward, in the radius middle part hole for hoist is arranged, be arranged at intervals with 3～6 flexible lines of rabbet joint on the excircle of blade bodies.This saw blade can effectively be alleviated the tension of bearing between saw blade excircle sawtooth, reduces the sensitiveness of sawtooth root crack output, reduces crackle and produces tendency, postpones the generation of saw blade crackle.Compare with the conventional metals cold hot cut circular saw blade, under saw equipment, the rational condition of operating procedure conditional stability, can effectively improve saw blade service life.
Summary of the invention
The object of the present invention is to provide a kind of have efficient height, environmental protection, cutting accuracy advantages of higher, be mainly used in the sintered carbide circular saw of cutting steel, steel plate, iron and steel etc.
The present invention is provided with circular saw bench and sawtooth, and circular saw bench is provided with centre bore.Sawtooth is welded on the toothholder of circular saw bench, and anterior angle is 0 °～3 °, and relief angle is 8 °～13 °, and back rake angle is 0 °～5 °, and paying the drift angle is 1 °～2 °, and paying the inclination angle, drift angle is 1 °～2 °.
Sawtooth can be 20～100, can be selected according to the size and the requirement of client of circular saw bench.
Anterior angle is preferably 0 °, and relief angle is preferably 10 °, and back rake angle is preferably 0 °.
Compare with existing saw blade, because the present invention does not become common folding back of the body tooth, circle-arc tooth, dovetail tooth to tooth Shape Design, but be designed to U type tooth, therefore profile of tooth of the present invention not only increases the intensity of saw blade, and has an advantage of big roller seating space, big roller seating space can overcome existing saw blade and be not easy shortcomings such as chip removal and reconditioning, has also improved the heat sinking function of saw blade in working angles.Because the anterior angle of sawtooth is designed to 0 °～3 °, especially 0 °, therefore when cutting steel, strengthened the cutting contact area, can prevent breaking of sawtooth, increase the service life.Because relief angle is designed to 8 °～13 °, especially 10 °, therefore can prevent saw blade when cutting because of the wearing and tearing of the sawtooth alloy matrix of damaging, thereby influence the rigidity of whole saw blade.Owing to back rake angle is designed to 0 °～5 °, especially 0 °, can better prevents breaking of sawtooth.Paying the drift angle and paying in the selection at inclination angle, drift angle, the present invention all adopts 1 °～2 °, is different from existing wide-angle commonly used, therefore under the prerequisite that guarantees cutting effect, can prevent that the saw blade that causes because of crimp from damaging.
