Abstract
(B, ) the utility model relates to an improve bands for band of speed of saw cutting, the anterior angle of inclination of each trapezoidal sawtooth is 12 - 16 in this bands for band, and the rear portion angle of inclination of trapezoidal sawtooth is 15 - 20. Anterior angle of inclination and rear portion angle of inclination that this bands for band adopted can not make the prong produce the resilience phenomenon at the in -process that saw cuts the material, and the prong does not kick -back and can improve the speed of saw cutting the material greatly on the one hand, and not fragile when saw cutting the material at a high speed, and on the other hand can increase the power of saw cutting (b) (b). (B, )
Description
Technical field
the utility model relates to a kind of bands for band improving saw cutting speed.
Background technology
no matter existing bands for band is bi-metal bandsaw blades, or hard alloy band saw blade, the sawtooth that saw band is arranged and saw band tilt, and the direction making adjacent two sawtooth tilt is contrary, and angle of inclination is identical, although this kind of bands for band also can cut ferrous materials, but the materials such as bands for band cutting stainless steel, titanium alloy, wear resistant tools steel, high temperature alloy and stone material described in utilizing very easily make it damage, and be difficult to the material of sawing surface roughness, so, the bands for band of this kind of structure not only service life shorter, and saw cutting speed is lower.
for this reason, the name of No. 202877649U, Chinese patent bulletin is called that " a kind of regardless of cingulum saw blade " provides a solution.Sawtooth in this kind of bands for band adopts trapezoidal, and the trapezoidal both sides of sawtooth and horizontal line angle α are 2 °-3 °.Although this kind of bands for band also can cut material, but for trapezoidal sawtooth, if the front rake angle of trapezoidal sawtooth and inclination angle, rear portion do not arrange suitable angle, be difficult to realize cutting materials such as stainless steel, titanium alloy, wear resistant tools steel, high temperature alloy and stone materials, and saw cutting speed also can not improve, so whether this kind of bands for band can improve the desirable cutting effect of saw cutting speed needs to inquire into further.
Summary of the invention
the purpose of this utility model is to provide a kind of bands for band utilizing adjustment derrated shaft to solve the raising saw cutting speed of the problems such as the slow and sawtooth of saw cutting speed is fragile to the mode at angle of inclination.
the bands for band of the raising saw cutting speed that the utility model proposes comprises annular saw band and is arranged on the trapezoidal sawtooth in annular saw band, and the front rake angle of each trapezoidal sawtooth described is 12 °-16 °, and the inclination angle, rear portion of trapezoidal sawtooth is 15 °-20 °.
described trapezoidal serration tips lateral length is 15-30 millimeter, and it is 0.5-1.0 millimeter that the lateral length of trapezoidal sawtooth lower end is less than top lateral length.
the vertical height of described trapezoidal sawtooth is 4-11 millimeter.
each pitch of described bands for band adopts 6 trapezoidal sawtooth.
the tilt inclination angle of its front portion of sawtooth in the bands for band of the raising saw cutting speed that the utility model proposes is 12 °-16 °, the inclination angle at rear portion is 15 °-20 °, the trapezoidal sawtooth of this kind of angle can not make crown produce rebound phenomenon in the process of sawing material, and crown not resilience can improve the speed of sawing material on the one hand greatly, and it is not fragile when high speed sawing material, sawing force can be increased on the other hand, so, utilize this kind of bands for band to can be used for the materials such as sawing stainless steel, titanium alloy, wear resistant tools steel, high temperature alloy, stone material and surface roughness.
accompanying drawing illustrates:
accompanying drawing 1 is the part schematic front view of a bands for band embodiment of the raising saw cutting speed that the utility model proposes;
accompanying drawing 2 is schematic top plan view of Fig. 1;
accompanying drawing 3 is that schematic diagram is looked on the left side that in Fig. 1, trapezoidal sawtooth amplifies.
detailed description of the invention:
see Fig. 1 to Fig. 3, these 3 accompanying drawings provide the partial appearance structural representation of a bands for band embodiment of the raising saw cutting speed that the utility model proposes.The trapezoidal sawtooth 2 that this bands for band comprises annular saw band 1 and is arranged in annular saw band 1, annular saw band 1 wherein only provides the surface structure of 7 trapezoidal sawtooth 2; Providing trapezoidal sawtooth 2 front rake angle γ in the present embodiment is 14 °, and rear portion inclined angle alpha is 18 °; And the lateral length on trapezoidal sawtooth 2 top 21 is 25 millimeters, the lateral length of its lower end 22 24.2 millimeters, being less than trapezoidal sawtooth 2 top 21 is 0.8 millimeter, and the vertical h of trapezoidal sawtooth 2 is highly 9 millimeters.
for bands for band, angle and the lateral length of trapezoidal sawtooth 2 can be set according to annular saw band 1 width of bands for band and thickness, under normal conditions, the front rake angle of trapezoidal sawtooth 2 can be set to 12 °-16 °, inclination angle, rear portion is set to 15 °-20 °, trapezoidal sawtooth 2 top 21 lateral length is set to 15-30 millimeter, the lateral length of lower end 22 is less than top lateral length and is set to 0.5-1.0 millimeter, the vertical h of trapezoidal sawtooth 2 is highly 4-11 millimeter, and makes each pitch of bands for band adopt 6 trapezoidal sawtooth 2.
Claims (4)
1. improve the bands for band of saw cutting speed, this bands for band comprises annular saw band and is arranged on the trapezoidal sawtooth in annular saw band, and it is characterized in that: the front rake angle of each trapezoidal sawtooth described is 12 °-16 °, the inclination angle, rear portion of trapezoidal sawtooth is 15 °-20 °.
2. bands for band according to claim 1, is characterized in that: described trapezoidal serration tips lateral length is 15-30 millimeter, and it is 0.5-1.0 millimeter that the lateral length of trapezoidal sawtooth lower end is less than top lateral length.
3. bands for band according to claim 1, is characterized in that: the vertical height of described trapezoidal sawtooth is 4-11 millimeter.
4. bands for band according to claim 1, is characterized in that: each pitch of described bands for band adopts 6 trapezoidal sawtooth.
