Description

The tooth pitches such as multiple tooth type become the high saw blade of tooth

Technical field

The utility model relates to the technical fields of saw blade, and in particular to a kind of tooth pitches such as multiple tooth type become the high saw blade of tooth.

Background technique

Saw blade is the steel disc item for being provided with land, and land is the major part of saw blade.

In saw blade, the structure of sawtooth is to determine the principal element of saw blade performance.For configuration aspects, current sawtooth Usually there are full-height tooth, displacement tooth and hook tooth several, wherein full-height tooth is most common flute profile, is suitble to the different types of material of cutting Material, due to no anterior angle, the strand material for being suitble to cutting thin or small diameter is typically used as normal usage.Displacement tooth has due to it The tooth pitch of variation has fabulous cutting bearing capacity, and can reduce vibration when cutting, so that the service life of sawtooth Long, cutting noise is small, and notch is smooth and more efficient, especially suitable for cutting the irregular shape material easily vibrated, i.e., Make high-speed cutting, sawtooth will not be crushed.Tooth is hooked since it is with positive rake angle, narrowband is obtained greatly apart from tooth socket, has fabulous Nonmetallic chip removal ability, be suitable for high speed high-rate cutting, for cutting when generate spiral helicine big sawdust material be particularly suitable for, It is mainly used for nonmetallic cutting, so that smooth cut, cutting speed is fast.

In addition, the tooth pitch and tooth height of sawtooth are the principal element for determining saw blade performance in saw blade.It is cut for different Cut article, it is necessary to design different saw blades to meet its cutting and require.

But as the use scope of current saw blade is more and more extensive, the article of required cutting is also more and more many and diverse, at present Saw blade be difficult to meet the cutting requirement of some special articles.So it is extremely urgent to develop a kind of new structural saw blade.

Specific embodiment

Become the high saw blade of tooth to tooth pitches such as multiple tooth types described in the utility model below by specific embodiment to make further Detailed description.

As shown in Figure 1 and Figure 2, the tooth pitches such as multiple tooth type become the high saw blade of tooth, are made of base band 4 and sawtooth 5, in what is longitudinally extended Rectangular slat shape has longitudinal extension and opposite upper top surface and bottom surface, two opposing and longitudinally extending sides and two Opposite end face；Its bottom surface is working face, and upper top surface is non-working surface；Several sawtooth are provided in the bottom surface Group, the tooth pitch in each sawtooth group between adjacent teeth are identical.Wherein the both ends of each sawtooth group are positioning tooth, two positioning tooths it Between sawtooth 5 is the hawk bill teeth 2 that is spaced apart one by one and hooks tooth 3, the positioning tooth is full-height tooth 1, the full-height tooth 1 by front, Tooth socket is constituted with bottom of the tooth circular arc below, is equidistant between sawtooth 5, anterior angle is 0 degree；The hawk bill teeth 2 is by front, back and tooth Bottom circular arc constitutes tooth socket, is followed successively by inclined-plane, plane and arcwall face by the tooth tip of sawtooth 5 behind, wherein inclined-plane and level Included angle between face is between 60 ~ 70 degree；3 anterior angle of hook tooth is positive value, and anterior angle angle is between 1 ~ 8 degree.

Preferably, hawk bill teeth 2 is high different with the tooth for hooking tooth 3 in each sawtooth group, high 5 top of phalanges saw tooth of tooth Vertical range to tooth socket minimum point.The 15 ~ 20% of a height of entire saw blade width of the tooth of the hawk bill teeth 2 hook the tooth of tooth 3 The 9 ~ 14% of a height of entire saw blade width.

Preferably, the hawk bill teeth 2 in each sawtooth group is the oblique tooth in a left side of left direction run-off the straight, is hooked Tooth 3 is the oblique tooth in the right side of right direction run-off the straight, and hawk bill teeth 2 and the hook inclined angle of tooth 3 are symmetrical.

An embodiment of the present invention, each sawtooth group are made of five sawtooth 5, are followed successively by and are in saw blade Conplane full-height tooth 1, the hawk bill teeth 2 being tilted to the left, the hook tooth 3 being tilted to the right, the hawk bill teeth 2 and saw blade being tilted to the left In conplane full-height tooth 1.

Another embodiment of the utility model, each sawtooth group are made of seven sawtooth 5, be followed successively by at saw blade In conplane full-height tooth 1, the hawk bill teeth 2 being tilted to the left, the hook tooth 3 being tilted to the right, the hawk bill teeth 2 being tilted to the left, to the right The inclined hawk bill teeth 2 for hooking tooth 3, being tilted to the left is in conplane full-height tooth 1 with saw blade.

The tooth pitches such as above-mentioned multiple tooth type become the high saw blade of tooth, use hawk bill teeth 2 and hook the spaced mode of tooth 3, use The form of equal space widths, and using the high alternate structure of different teeth, hawk bill teeth 2 is similar to the combination of full-height tooth 1 and curvature of the spinal column tooth, With sharp tooth tip and the high-intensitive back of tooth.Hook 3 anterior angle of tooth be positive value, the ratio between tooth depth and tooth pitch are relatively small, cutting slot compared with Shallowly.When carrying out sawdust to the higher article of hardness, for cutting, lower hook tooth 3 is further cut simultaneously higher hawk bill teeth 2 And chip removal can be convenient for, and saw blade intensity can be improved, saw blade damaged probability is reduced, the service life of saw blade is extended.

The principles and effects of the utility model creation, and the reality that part uses only is illustrated in the above embodiments Example is applied, is rather than limited the present invention；It should be pointed out that for those of ordinary skill in the art, not departing from this Under the premise of utility model concept, various modifications and improvements can be made, these belong to the protection of the utility model Range.
