Description
Technical field
The present invention relates to a kind of rotational oscillation saw blade that is used to have the toolroom machine of rotational oscillation drive unit.
Background technology
The driven saw blade in a kind of whirling vibration ground has been described in WO 2008/151866 A1.Said saw blade is made up of main leaf and a cutting bar that adapts to said main leaf of part circular.Main leaf is embodied as independent member with the cutting bar, but is mutually permanently connected.Because main leaf is embodied as independent member with the cutting bar,, for example uses the softer material that helps damped vibration, and use harder material to improve cutting force for the cutting bar for main leaf so can use material different for main leaf and cutting bar.
This saw blade is owing to the rotational oscillation drive unit receives high alternate load, and this is because saw blade changes direction of rotation with high-frequency.This produces high acceleration and shearing force, thereby maybe reduction of service life.In addition, particularly can be in the high engine speed range of toolroom machine with the intrinsic frequency of saw blade excitation saw blade, thereby cutting ability and possibly further worsening service life.
Summary of the invention
The objective of the invention is to, construct a kind of rotational oscillation saw blade in this wise, make the service life that is improved with measure simple in structure.It should reduce the danger of the vibrational excitation of saw blade especially.
According to the present invention, this purpose solves through rotational oscillation saw blade according to the present invention.Dependent claims has been explained favourable improvement project.
The rotational oscillation saw blade uses in the toolroom machine with rotational oscillation drive unit, and wherein, toolroom machine is hand held power machine preferably.In the rotational oscillation drive unit, drive said saw blade crankmotion with high-frequency.The rotational oscillation saw blade comprises a main leaf and a cutting zone that is arranged on the main leaf, and wherein, said saw blade is bearing in through said main leaf on the tool spindle of said toolroom machine, and said cutting zone has the cutting teeth that is arranged on the excircle.Said cutting zone and main leaf can be implemented in principle integratedly, wherein, also can be embodied as independent member connected to one another within the scope of the invention two-piece type.
According to the present invention, in said main leaf, offer at least one and fall dead slot, said the excircle that dead slot extends to said cutting zone always falls, promptly extend to cutting teeth always.Said the vibration characteristics of dead slot change saw blade of falling.Therefore can on purpose influence the intrinsic frequency and the resonance characteristics of saw blade, particularly avoid the excitation of rotating speed in the intrinsic frequency scope through toolroom machine.Fall dead slot and cause the imbalance of driving frequency aspect, and can after saw blade is accomplished, be offered without a doubt.Can avoid on the toolroom machine range of speeds of confirming through electric drive motor and transmission device, encouraging the scope internal resonance of saw blade in this way in intrinsic frequency.
In case of necessity, also can reduce shearing force, because on direction of rotation, the rigidity of said main leaf reduces at least a little, and correspondingly, said main leaf has softer vibration characteristics when direction of rotation changes, reduce peak load thus.
Said the dead slot that falls advantageously extends fully in the axial direction and penetrates said saw blade.But in principle, said the dead slot that falls also can be only extends on the part of the axial width of said saw blade, thereby in said main leaf or in cutting zone, breach do not occur.
Suitable in addition is, on circumference, a plurality of dead slots that fall is set with distributing, and these fall dead slot and particularly are arranged in symmetrically on the said saw blade.Two, three or four dead slots that fall that extend respectively up to excircle for example can be set.
Fall the adjacent layout of dead slot and excircle or said and fall the mode that dead slot extends up to the excircle of saw blade and have following advantage, promptly because the higher circular acceleration on excircle, falling dead slot through introducing provides better effect.In addition, avoid said main leaf in the zone at supporting position, to weaken, realize and being connected of tool spindle through this supporting position.
Fall dead slot and for example be embodied as notch shape, wherein, the wall section that separates through otch perhaps according to further embodiment, has one to when young interval at saw blade not under the stress state or directly not against each other each other.Said otch self is embodied as or straight line, and is perhaps crooked, and in addition, the embodiment with a plurality of otch sections placed adjacent one another also is possible, and said otch section itself forms straight or curved respectively.
Fall dead slot and have the section that at least one radially extends aptly, this section extends to the excircle of said saw blade always.Said the dead slot that falls has a section on the side of said excircle, this section is upwards extending or upwards having at least one component in week in week.Combine to obtain thus a T shape or L shaped dead slot or the otch that correspondingly is shaped with the section that radially extends, point to excircle.But, snakelike or corrugated the dead slot that falls that for example combines by the single section of bending respectively, the dead slot of the zigzag that is perhaps combined by linear section also is feasible.
Said the dead slot that falls is aptly at the mid point that not exclusively extends in the radial direction up to said saw blade, but only on a segment section radially, extends.Therefore, what possibly suit is, falls dead slot only from extend internally half the up to radius of the excircle of said saw blade, perhaps only radius 1/4th or also on littler radially highway section, extend.
According to further simplified example, the tooth root that dead slot is configured to the intensification between two adjacent teeth on the excircle falls.Make in the simple embodiment at this, only need deepen the tooth root between two adjacent teeth diametrically.The trend that can keep the common cavetto of said tooth root here.But also feasible is radially inwardly to construct said the dead slot that falls according to the type of otch from normal tooth root.
Said saw blade can be constructed conglobate or fan-shaped.Fan-shaped saw blade extends on less than 360 ° angular range, wherein, is admissible greater than 180 ° fan-shaped not only, and also is admissible less than 180 ° fan-shaped.
