Abstract
The utility model relates to a saw blade, particularly a hard alloy band saw blade. The hard alloy band saw blade belongs to the processing tool. The hard alloy band saw blade is composed of a saw band body, and hard alloy saw teeth. The hard alloy band saw blade is characterized in that the saw band body is circular, and the saw band body is soldered with the hard alloy saw teeth. The hard alloy saw teeth are characterized in that the ends are thick, the roots are narrow, every three teeth are arranged in a set, a saw line is sawed, the three teeth are staggered mutually, and one third of the saw line is sawed by each saw tooth. The saw blade is used for sawing the hardworking materials of the high-temperature alloy, the infinite chilled nodular cast iron, the alloy tool steel, the die steel, the heat-resisting stainless steel, etc. The problems that the efficiency is low when a bimetallic tool steel band saw blade is used for sawing the high-temperature alloy, the alloy tool steel, the die steel, and the heat-resisting stainless steel, the service life is short, and the infinite chilled nodular cast iron can not be sawed are solved.
Description
The utility model relates to a kind of saw blade, and especially a kind of hard alloy band saw blade belongs to the machining tool class.
At present, the saw blade that technology applied metal, nonmetallic materials sawing now processed, generally use strip, band shape, plate-like various ways, yet the sort of form no matter, they belong to the same one that sawtooth combines with body (strip, band shape, plate-like), this with the integrative-structure form, though have certain advantage; For example: make processing simply, conveniently, yet often can not satisfy the needs of sawing difficult-to-machine material.The saw of this integral structure makes hackle distortion, rust, chip removal difficulty through regular meeting, and sawing is crooked, and processing effect is poor, efficient is low, and service life is short.
The purpose of this utility model provides a kind of hard alloy band saw blade, solves 95207113.4 side set type hard alloy band saw blades of original application, and bidentate does not have middle tooth for one group, the problem that sawing wanders off easily.It mainly is made up of saw band body (1), carbide alloy sawtooth (2), it is characterized in that saw band body (1) is annular shape, and carbide alloy sawtooth (2) in the soldering on it; Carbide alloy sawtooth (2) is characterized by that the sawtooth termination is wide, root is narrow, and one group of sawing one swage set of its per three teeth, intermeshes 1/3rd of every sawtooth sawing swage set.The head saw of carbide alloy sawtooth (2) is cut kr0 °-18 ° of sword drift angles, anterior angle r
00 °-18 °.Relief angle a
06 °-18 °, chamfering B30 °-48 °, auxiliary angle kr
11 °-6 °, front clearance a
0 11 °-6 °, cutting edge inclination is gone into
s0 °-16 °, select different angles according to the sawing different materials.
The utility model compared with prior art has sword hardness height, anti-wear performance is good, sawdust is narrow, chip removal is easy, long service life, and processing effect is good, the efficient height, and sawing is difficult for wandering off.
Further specify below in conjunction with accompanying drawing and example:
Fig. 1: for the utility model wherein one section overall structure master look schematic diagram;
Fig. 2: be the schematic top plan view after one group of serrated portion amplification of Fig. 1;
Fig. 3: for the master after one group of serrated portion amplification of Fig. 1 looks schematic diagram;
Fig. 4: be the left view after the LS serrated portion amplification of Fig. 1;
Fig. 5: be the left view after the ZS serrated portion amplification of Fig. 1;
Fig. 6: be the left view after the RS serrated portion amplification of Fig. 1;
Among the figure: 1 is the saw band body, and 2 is the carbide alloy sawtooth, and S is a saw kerf width, and RS is a right sawtooth end width, and ZS is a middle sawtooth end width, and LS is a left sawtooth end width, and Kr is that head saw is cut the sword drift angle, and B is a chamfering, r
0Be anterior angle, a
0Be relief angle, kr
1Be auxiliary angle, a
0 1Be front clearance, λ
sBe cutting edge inclination.
As can be seen from the figure:
The utility model, it mainly is made up of saw band body (1), carbide alloy sawtooth (2), it is characterized in that saw band body (1) for ring-type, and carbide alloy sawtooth (2) in the soldering on it; Carbide alloy sawtooth (2) is characterized by that the sawtooth termination is thick, root is narrow, and one group of sawing one swage set of its per three teeth, 1/3rd of every sawtooth sawing swage set.It is 0 °-18 ° that the head saw of carbide alloy sawtooth (2) is cut sword drift angle kr, anterior angle r
0Be 0 °-18 °, relief angle a
06 °-18 °, chamfering B are 30 °-48 °, auxiliary angle kr
1Be 1 °-6 °, front clearance a
0 1Be 1 °-6 °, cutting edge inclination λ
sIt is 0 °-16 °.Select different angles according to the sawing different materials.
This bands for band is used for difficult-to-machine materials such as sawing high temperature alloy, indefinite chill spheroidal graphite cast-iron, alloy tool steel, mould steel, heat-resistance stainless steel, solved bimetallic tool steel bands for band, sawing high temperature alloy, alloy tool steel, mould steel, heat-resistance stainless steel efficient are low, service life is short, to indefinite chill spheroidal graphite cast-iron can not sawing problem.
