Abstract
The utility model relates to a saw blade, particularly a hard-alloy band saw blade. The utility model belongs to the class of processing tools. The utility model is mainly composed of a saw band body and hard-alloy saw teeth. The utility model is characterized in that the saw band body is in a ring shape and is welded with the hard-alloy saw teeth. The hard-alloy saw teeth are characterized in that the end part of the saw teeth is wide, the root is narrow, and two teeth are in one group for sawing a saw kerf. The saw blade is used for sawing materials such as copper, aluminium, non-ferrous metal, hardwood, plastics, glass fibre reinforced plastics, etc. The utility model solves the problems of short service life of bimetallic tool-steel band saw blades for sawing and cutting copper and aluminium, and short service life of woodworking band saw blades for sawing and cutting hardwood.
Description
The utility model relates to a kind of saw blade, and especially a kind of hard alloy bands for band belongs to the machining tool class.
At present, technology is applied to metal now, the saw blade of nonmetallic materials sawing 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 objective of the invention is to overcome above-mentioned defective.
The purpose of this utility model is achieved in that it mainly is made up of saw band body (1) carbide alloy sawtooth (2) and it is characterized in that saw band body (1) for annular, and welds 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.The anterior angle r of carbide alloy sawtooth (2).0 ° 18 °, relief angle a.6°-26°。Chamfering B20 °-50 °, select different angles according to the sawing different materials.
The utility model compared with prior art has sawtooth sword hardness height, anti-wear performance is good, sawdust is narrow, chip removal easily, run not, long service life, processing effect is good, the efficient height.
Further specify below in conjunction with accompanying drawing and implementation column:
Fig. 1: be the utility model one section overall structure schematic diagram wherein.
Fig. 2: for overlooking after one group of serrated portion amplification of Fig. 1 looked intention.
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 serrated portion amplification of Fig. 1.
Fig. 5: be the left view after the serrated portion amplification of Fig. 1.
Among the figure: 1 is the saw band body: 2 are the carbide alloy sawtooth.S is a saw kerf width; R.Be anterior angle; A.Be relief angle; B is a chamfering.
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, and weld 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, and the anterior angle of carbide alloy sawtooth (2) is r.0 °-18 °, relief angle a.Be 6 °-26 °, chamfering B20 °-50 °, select different angles according to the sawing different materials.
This bands for band is used for materials such as sawing copper, aluminium, non-ferrous metal, hardwood, plastics, fiberglass, solved short and band saw bar sawing hardwood service life in bimetallic tool steel bands for band sawing copper, aluminium service life short problem.
