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 mainly 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 annular, and the hard alloy saw teeth are welded on the saw band body. The hard alloy saw teeth are characterized in that the ends of the saw teeth are wide, and the roots are narrow. Two teeth are arranged in a group, a saw line is sawed, the two teeth are interlaced right and left, and one twice of the saw line is sawed by each tooth. The saw blade is used for sawing the non-ferrous metal of the copper and the aluminium, the hardwood, the plastic, and the glass-reinforced plastic material. The problems that the service life of the bimetallic tool steel band saw blade is short for sawing the copper and the aluminium and the service life of the woodworking band saw blade is short for sawing the hardwood are solved.

Description

Hard alloy band saw blade

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, present technology applied metal, nonmetallic materials are according to cutting the saw blade of processing, generally use strip, band shape, plate-like various ways, yet the sort of form no matter, they all belong to the same one that sawtooth combines with body (strip, banded plate-like), and are 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, and efficient is low, and service life is short.

The purpose of this utility model is achieved in that it mainly is made up of saw band body (1), carbide alloy sawtooth (2).It is characterized in that saw band body (1) is ring-type, and weld carbide alloy sawtooth (2) 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 per two teeth, about staggered, every sawtooth saw pin swage set

The head saw of carbide alloy sawtooth (2) is cut kr3 °-18 ° of sword drift angles, anterior angle r _o0 °-18 °, relief angle α _o6 °-18 °, chamfering B30 °-48 °, 1 °-6 ° of auxiliary angle Kr ', front clearance α _o' 1 °-6 °, 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 suburb fruit is good, the efficient height.

Further specify below in conjunction with drawings and Examples:

Fig. 1: for the utility model wherein one section overall structure master look schematic diagram;

Fig. 2: for looking schematic diagram in the mansion 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 RS serrated portion amplification of Fig. 1.

Among the figure: 1 is the saw band body; 2 is the carbide alloy sawtooth; S is a saw kerf width; RS is a right sawtooth end width; LS is a left sawtooth end width, and kr is that head saw is cut the sword drift angle; B is a chamfering; r _oBe anterior angle; α _oBe relief angle; Kr ' is an auxiliary angle; α _o' be front clearance.

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) is ring-type, welds carbide alloy sawtooth (2) 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 per two teeth, every sawtooth sawing swage set

It is 3 °-18 °, anterior angle r that the head saw of carbide alloy is cut sword drift angle kr _oBe 0 °-18 °, relief angle α _o6 °-18 °, chamfering B are that 30 °-48 °, auxiliary angle kr ' are 1 °-6 °, front clearance α _o' be 1 °-6 °.Select different angles according to the sawing different materials.

This bands for band is used for sawing copper, aluminium, non-ferrous metal, hardwood, plastics, glass-reinforced plastic material, has solved bimetallic instrument steel band steel bar sawing copper, aluminium short and band saw bar sawing hardwood short problem in service life in service life.
