Abstract

The utility model discloses a diamond-coated alloy saw blade, which is specially used for cutting plywood boards and composite boards. The diamond-coated alloy saw blade comprises a substrate, support components and alloy tool bits, wherein the support components (with corresponding number) are uniformly and fixedly arranged on the circumference of the substrate at equal intervals, and the same side faces of the support components are respectively fixedly connected with an alloy tool bit; each two adjacent support components are respectively fixedly connected with an alloy tool bit and another alloy tool bit, the structures of the alloy tool bit and the another alloy tool bit are same, the sizes of the two are consistent, and the installation positions of the two are opposite; and the alloy tool bit and the another alloy tool bit are respectively fixed with a diamond film layer (0.5 to 1.0 mm) at the two sides of the support component. The diamond-coated alloy saw blade disclosed by the utility model has the advantages that by using the ultra-high hardness and sharp cutting edges of diamond particles, the service time and cutting speed of the saw blade are greatly improved; and because the diamond film is deposited on the support part, the overall stability of the saw blade is improved, and the probability of tooth breakup is reduced.

Description

A kind of diamond coatings alloy saw blade

Technical field

The utility model relates to a kind of diamond coatings alloy saw blade, is exclusively used in the cutting of glued board, composite board.

Background technology

Along with the development of society, emerging Building Decoration Materials such as glued board, three-ply board be applied to just more and more widely the house structure, the decoration in; The general employing of the cutting tool of these emerging Building Decoration Materials cut the wood saw sheet, and defective of cutting the wood saw sheet commonly used is: saw kerf is rough smooth, consumes quite fast, service life is very short, and chip removal difficulty, timber be the meeting variable color after cutting, is difficult to the split requirement that reaches higher.

Summary of the invention

The purpose of this utility model is for overcoming above the deficiencies in the prior art, a kind of wear-resisting diamond coatings alloy saw blade is provided, both had the advantage that alloy saw blade is cut wood, having the wear-resisting character of diamond saw blade again, the service life of having improved saw blade greatly.

The technical solution adopted in the utility model is: comprise matrix, support component and alloy cutter head, be set with the support component of corresponding number on the circumference of matrix evenly and at intervals, be fixedly connected with alloy cutter head on the same side of each support component, be fixedly connected with an alloy cutter head and another alloy cutter head respectively on every adjacent two support components, one alloy cutter head is identical with another alloy cutter head structure, consistent size and installation site are relative, an alloy cutter head and another alloy cutter head with the both sides of going into support component on the fixing diamond rete of one deck 0.5mm～1.0mm respectively.

The beneficial effects of the utility model are:

1, utilizes the ultrahigh hardness of diamond particles and sharp cutting edge, improved the life-span and the cutting speed of saw blade greatly.

2, at support section depositing diamond film, improved the resistance to overturning of saw blade, reduced the probability that collapses tooth.

3, adopt silver-bearing copper component alloy weld tabs, utilize laser that alloy cutter head is welded on the saw bit matrix, increased the adhesion of alloy cutter head and support section; In addition, because copper sheet is softer, the vibration when having partially absorbed cutting.

4, on saw bit matrix, do stress and handle, can offset saw blade suffered resistance when cutting, reduced the deformation of saw blade.

alloy cutter head

6,7 on the same side of each support component 1, alloy cutter head 6 and alloy cutter head 7 adjacent being interspersed, a difference fixedly connected

alloy cutter head

6 and 7 on promptly every two adjacent support components 1.Alloy cutter head 6 is the alloy weld tabs that silver and copper are formed, and utilizes laser weld on support zone 1.Alloy cutter head 6 is identical with 7 structures, consistent size, but when installing, alloy cutter head 6 is relative with 7 position, sees Fig. 2 and Fig. 3.The centre bore of matrix 4 is an installing hole 5, also has a plurality of expansion slots 2 and radiating groove 3 on the relevant position of matrix 4.

Alloy

cutter head

6 and 7 and the both sides of support component 1 on the fixing diamond rete 8 of one deck 0.5mm～1.0mm respectively, add man-hour, can adopt direct-current plasma jet chemical vapor deposition unit to deposit this diamond rete 8.Alloy

cutter head

6 and 7 cutter head side are an inclined-plane that has a constant slope, and the angle of inclination is 1 °, and the angle of inclination of alloy cutter head 6 is D1 among Fig. 2, and the angle of inclination of alloy cutter head 7 is D2 among Fig. 3, promptly D1=D2=1 °.The cutter head relief angle of alloy cutter head 6 is C1 among Fig. 2, and the cutter head relief angle of alloy cutter head 7 is C2 among Fig. 3, and C1=C2, C1 and C2 are 10 °～13 °, and purpose is to make alloy cutter head bring into play dissection the biglyyest.
