Description
Technical field
The invention belongs to B27B：The saw of processing for timber or similar material.
Background technology
Existing door-plate size pattern is various, it is therefore desirable to bulk door-plate be cut into polylith, need to cut using door-plate
Saw.Existing door-plate cast-cutting saw mostly uses disc saw blade, and the high speed rotation under motor drive carries out cutting operation.In order to carry
High working efficiency is often connected in multi-disc circular saw bit on one mandrel, it is primary it is cleavable go out multi-disc plank.But due to saw
Piece must have enough intensity, cannot be too thin, will produce high temperature when especially saw blade cuts timber, reduce the intensity of saw blade,
In order to resist high temperature deformation, saw blade will increase a part of thickness on the basis of meeting normal temperature strength.For this purpose, it is desirable to cut
Saw has good heat dissipation performance, so that the thickness of saw blade is preferably minimized.But saw blade is cut inside timber, and has sawdust
It surrounds, heat dissipation is difficult.The cast-cutting saw especially contacted, heat dissipation performance are worse.In addition timber and plank cannot all get wet, more
It cannot be stained with oil, coolant liquid cannot be used, thus saw blade cooling becomes a problem.
Invention content
The invention is intended to provide a kind of door-plate cast-cutting saw, to solve the problems, such as that existing door-plate cast-cutting saw heat dissipation performance is poor.
Door-plate cast-cutting saw in this programme, including saw disc, the saw disc are provided centrally with rotation axis, and the saw disc upper edge turns
Moving axis is equipped with several cavitys, slidably connects piston plate in the cavity, the piston plate by cavity be divided into the first cavity and
The side of second cavity, the piston plate is connected with spring leaf, and the spring leaf is in rugosity, and the piston plate is equipped with spring
The side of piece is connected with saw rod, and the sawtooth being located at outside cavity is equipped with above the saw rod, and the sawtooth side wall is equipped with limit
Block and iron block, the limited block are located on the inside of iron block, heat emission hole are provided on the saw disc, the side wall of the cavity is equipped with several
A through-hole.
The working principle and beneficial effect of above-mentioned technical proposal is：When sawtooth touches door-plate, sawtooth end of door plate generates
Pressure, door-plate generate reaction force to sawtooth, to make sawtooth there are one along the downward component of cavity, are sawed since sawtooth connects
Bar, saw rod are connected on piston plate, therefore when sawtooth works, component acts on piston plate, and piston plate is made to move down, to
The spring leaf of folding is set to be unfolded, the spring leaf of expansion plays the role of supporting the first cavity of saw disc and the second cavity, at this time can
The intensity of saw is improved, enabling capabilities of the mandrel to sawtooth are increased.
And during piston plate moves down, increase the second cavity in pressure, by the gas in the second cavity from
It is discharged in through-hole, the hot-air in cavity is discharged, when sawtooth leaves wood, saw rod is equipped with iron block, work of the iron block in centrifugal force
It under, moves up, to make spring leaf restore, piston plate moves up, and so that the through-hole in the second cavity sidewalls is sucked extraneous
Cold air, while making the through-hole being located in the first cavity sidewalls discharge hot-air, to realize in cavity and extraneous heat is handed over
It changes, improves the heat dissipation performance of mandrel, and be provided with heat emission hole on saw disc, can ensure the cooling of saw disc, improve the heat dissipation of saw disc
Performance.Using this scheme, the heat dissipation performance of saw disc and mandrel itself can not only be improved, and the intensity of sawtooth can be improved,
Improve the service life of sawtooth.
Prioritization scheme one, advanced optimizes as to base case, and the through-hole is communicated with heat emission hole.It is cut in sawtooth
Door-plate carries out will produce many sawdusts in cutting process, and sawdust can enter through-hole, and through-hole is communicated with heat emission hole so that sawdust is passed through
It is blown away using heat emission hole after crossing through-hole, improves the elimination efficiency of sawdust.
Prioritization scheme two, as advanced optimizing to prioritization scheme one, the heat emission hole is oblique along the rotation direction of saw disc
To setting.Angularly disposed heat emission hole caters to the rotation direction of saw disc, when blowing air over heat emission hole, so that saw disc is had and turns with saw disc
The dynamic identical torque in direction, can further promote the rotation of saw disc.
Prioritization scheme three, as advanced optimizing to prioritization scheme two, the circumferential side wall of the heat emission hole, which is equipped with, to disappear
Sound-absorbing layer.The circumferential side wall of heat emission hole is equipped with noise reduction layer, can greatly reduce the noise in saw disc motion process.
Prioritization scheme four, as advanced optimizing to prioritization scheme three, the inflection point of the spring leaf is connected with idler wheel, institute
Roller-coaster is stated to be connected in cavity.When spring leaf be unfolded or shrink when, idler wheel can be rolled along cavity, by spring leaf with
Sliding friction between cavity is converted to rolling friction, significantly reduces the abrasion of spring leaf, and improve spring leaf uses the longevity
Life.
Prioritization scheme five, as advanced optimizing to prioritization scheme four, the aperture of the through-hole is the 1/ of saw disc diameter
20, the aperture of the heat emission hole is the 1/15 of saw disc diameter.For sawtooth after cutting door-plate, the aperture of through-hole is smaller can to prevent wind
Speed is excessive, so that sawdust is repelled to sawtooth position, sawtooth is caused to damage；The aperture of heat emission hole is larger can to ensure what saw disc generated
Heat can quickly flow out, and improve the radiating efficiency of saw disc.
