Abstract
The utility model relates to metallurgical saw blades and more particular to a cemented carbide tipped circular saw blade comprising a saw blade body and a cemented carbide tool bit, wherein the cemented carbide tool bit is welded on a tip seat around the circumference outside the saw blade body and is ground to have tipped saw edges which include front angles, rear angles, and sawing edges, the sawing edges referring to wave-like transverse edges. As the utility model is in application, the cutting edges and a workpiece are positioned by the recessed and protruding shapes, which can stabilize sawing and strengthen short and broken degree and smooth discharging of chips. Compared with prior art TP teeth such as regular rough sawing tip, precise cutting tip, the utility model can reduce quantity of grinding for tip profile, increase production efficiency, and find especial application to sawing such as seamless steel pipe, and H steel pipe.
Description
Technical field
The utility model relates to metallurgical saw, particularly a kind of hard-metal insert saw blade.
Background technology
Traditional hard-metal insert saw blade is made up of saw blade lamellar body and carbide bit two parts, and carbide bit is fixed by welding on the manufactured lamellar body, and then the carbide bit grinding being gone out required flute profile can cut.The cutting edge that carbide bit grinding at present goes out is the ordinary straight chisel edge, and it does not have the positioning and guiding effect to the saw blade feed motion when cutting, and saw blade integral body may produce bigger oscillating quantity during sawing, influences working durability and sawing effect.
Summary of the invention
The utility model is intended to improve the sawing effect of existing hard-metal insert saw blade, and provides a kind of and improve the sawing precision, prolongs the saw blade hard-metal insert saw blade in service life.
The technical solution adopted in the utility model is: a kind of hard-metal insert saw blade, comprise saw blade lamellar body, carbide bit, this carbide bit is welded on the toothholder on the saw blade lamellar body excircle, the carbide bit grinding has the sawtooth sword, the sawtooth sword comprises anterior angle, relief angle and cutting edge, and described cutting edge is the waveform chisel edge.
The utility model is when sawing, and cutting edge and workpiece are by the concaveconvex shape location, and the stability when helping improving sawing has been strengthened the disconnected broken degree of smear metal and the smooth and easy discharge of smear metal.Compare with TP tooth of the prior art (common roughing tooth, finishing tooth), can reduce the grinding amount of flute profile, enhance productivity, especially be fit to the sawing of seamless steel pipe, H shape steel tube.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the waveform chisel edge cutter head of indent in the middle of the cutting edge.
Fig. 4 is the waveform chisel edge cutter head of evagination in the middle of the cutting edge.
Fig. 5 is the waveform chisel edge cutter head of evagination both sides indent in the middle of the cutting edge.
Among the figure: saw blade lamellar body 1, toothholder 2, carbide bit 2, centre bore 4, transmission circular hole 5, cutting edge 6.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The described hard-metal insert saw blade of present embodiment as shown in Figure 1 and Figure 2, it is made of saw blade lamellar body 1 and carbide bit 2, this saw blade lamellar body 1 is that have centre bore 4, a centre bore 4 of being made by alloy tool steel is evenly distributed with the disk of several transmission circular holes 5 in addition, carbide bit 2 adopts the P25-P40 ultrafine gain size to make, mode by soldering is connected on the toothholder 2 of disk outer rim, the carbide bit grinding has the sawtooth sword, the sawtooth sword comprises anterior angle, relief angle and cutting edge 6, and described cutting edge 6 is the waveform chisel edge.
Look different sawing requirements, described cutting edge 6 can be the waveform chisel edge (see figure 3) of middle indent, also can be the waveform chisel edge (see figure 4) of middle evagination, can also be the waveform chisel edge (see figure 5) of middle evagination both sides indent; Cutting edge 6 its waveforms of all sawtooth can be identical on described saw blade lamellar body 1 excircle, also can be by the positive and negative waveform interlaced arrangement of forward and backward sawtooth, and all right random layout.
