Abstract
The utility model provides a hard alloy band saw blade, which is mainly used for band sawing machines, being composed of a band saw plate 2 and the saw teeth of the edge position of the band saw plate 2. The utility model is characterized in that the saw teeth of the edge position of the band saw plate 2 is fixed with hard alloy tooth blocks, and has the advantages of easy manufacture and processing, low cost and long service life.
Description
The utility model relates to a kind of hardware ﹠ tools, especially a kind of hard alloy band saw blade.
The band saw lathe, because the production efficiency height, saw kerf is narrow, blank size is high, thus in mechanical processing industry, be widely used, thus also increasing for the demand of bands for band.At present, the bands for band that each bands for band factory is produced is bimetallic high-speed tool hacksaw blade, being about to high-speed tool steel draws wire, reroll into flat filament, with vacuum electron beam welding equipment high-speed flat tool steel wire being welded on the spring steel then is on the saw plate of material, become the bimetallic billot, will being welded with high-speed flat tool steel wire one side again, to be processed into sawtooth heat-treating profiled through undue tooth, and this kind saw blade promptly is only to be the bimetal saw blade of high-speed tool steel in tooth top portion.The processing and manufacturing difficulty is big, the technology complexity, and the tooling cost height, and need import.
The purpose of this utility model provides a kind of simple in structure, easy to process, hard alloy band saw blade that cost is low.
Technical solution of the present utility model is: a kind of hard alloy band saw blade, form by the sawtooth of band saw plate 2, band saw plate 2 edges, and it is characterized in that: on the sawtooth of the edge of band saw plate 2, be fixed with hard-metal insert piece 1.
The utility model compared with prior art owing to be connected to the hard-metal insert piece on sawtooth, oversimplifies processing saw blade process, and a large amount of process equipments has been saved in operation easily.

Below in conjunction with drawings and Examples the utility model is described further: a kind of hard alloy band saw blade, form by the sawtooth of band saw plate 2, band saw plate 2 edges, it is characterized in that: on the sawtooth of the edge of band saw plate 2, be fixed with hard-metal insert piece 1.
Embodiment one, two: shown in Fig. 1,2,3,4,5,6,7,8,2 is the band saw plate, and its material is 65mm, and thickness is 1mm, triangle sawtooth (as shown in Figure 1) is processed in edge, 1 is the hard-metal insert piece, and it is shaped as cuboid (1mm * 1mm * 2.5mm), the consistency of thickness of thickness and band saw plate 2, be 1mm(as shown in Figure 3), hard alloy blocks 1 is integrally welded with the straight flange of sawtooth, and requires the upper end than the high 0.5mm of sawtooth, and purpose is the allowance of welding back as roll flute.Conventional brazing technology is adopted in welding between hard-metal insert piece 1 and the sawtooth, promptly is solder flux with the borax, is scolder with copper zinc thin plate.Along separate routes, promptly per three adjacent sawtooth are one group to sawtooth routinely, and one is straight-tooth (as shown in Figure 3) in the middle of it, the teeth directional left side (as shown in Figure 2) of a side adjacent with this straight-tooth, and the teeth directional right side of opposite side tilts (as shown in Figure 4).Present embodiment mainly is applicable to the high-speed tool steel to be sawtooth and band saw plate that use the back to eliminate.Be one with the hard alloy blocks weldering, this hard alloy band saw blade is that cost saving reduces cost, and prolongs its service life again.In order to make hard alloy blocks and band saw plate firm welding, can on sawtooth, process a square breach, to increase bonding area (as shown in Figure 5).
Embodiment three:
Shown in Fig. 9,10,11,12,13: 2 is the band saw plate, and its material is 65mn, thickness 1mm, and triangle sawtooth (as shown in Figure 9) is processed in edge.1 is hard alloy blocks, and it is shaped as flute profile, and groove and sawtooth be complementary, and keeps the gap of 0.2mm, and the sheet scolder is added within the gap, is adopting conventional brazing technology to weld.Because hard alloy blocks 1 two sides have certain angle (α °, β °) (shown in Figure 10,11), so sawtooth can adopt not shunt structure (shown in Figure 11,12,13).The cutting edge of hard-metal insert piece 1 has three kinds of forms, promptly flat sword, left bank sword, right bank sword (shown in Figure 11,12,13), and every adjacent three are one group and heavily obey setting.
Embodiment four:
Shown in Figure 14,15,16,17,18: 2 are the saw plate, and its material is 65mn, and thickness is 1mm, and triangle sawtooth (as shown in figure 14) is processed in edge.1 is hard alloy blocks, the end face triangularity, and be provided with the groove that is complementary with sawtooth, be enclosed within on the sawtooth and remain with the 0.2mm gap, in the gap, add the sheet scolder, brazing technology is routinely welded again, because hard alloy blocks 1 two sides have certain angle (α °, β °) (shown in Figure 14,15), so sawtooth can adopt not shunt structure (shown in Figure 16,17,18).The cutting edge of hard alloy blocks 1 has three kinds of forms, promptly flat sword, left bank sword, right bank sword (shown in Figure 16,17,18).Every adjacent three is one group, and heavily clothes are provided with.
Embodiment five:
Shown in Figure 19,20,21,22,23: 2 for its material of saw plate is 65mn, and thickness is 1mm, and sawtooth is processed in edge, and zigzag fashion is rectangle (as shown in figure 19).1 is hard alloy blocks, and be provided with the groove that is complementary with sawtooth, be enclosed within on the sawtooth, and reservation 0.2mm gap, in the gap, add the sheet scolder, brazing technology is routinely welded again, because the hard alloy blocks two sides have certain angle (α °, β °) (shown in Figure 20,21), so sawtooth can adopt not shunt structure (shown in Figure 21,22,23).The cutting edge of hard alloy blocks 1 has three kinds of forms, and promptly flat sword, left bank sword, every adjacent three of right bank sword (shown in Figure 21,22,23) are one group, and heavily clothes are provided with.
