Abstract
The invention relates to the field of wood processing, in particular to a wood cutting saw blade. The wood cutting saw blade comprises a saw blade matrix. A fixing hole for fixing the saw blade is formed in the center of the saw blade matrix. Sawteeth are evenly distributed on the periphery of the saw blade matrix. At least one semiconductor chilling plate is arranged at the position, outside the fixing hole, of the saw blade matrix. The cold ends of the semiconductor chilling plates face the sawteeth. A heat transfer conductor connected with each cold end is embedded in the saw blade matrix. The distance between each conductor and the sawtooth roots ranges from 10 mm to 15 mm. The fixing hole is formed by a heat conduction alloy ring. The heat conduction alloy ring and the saw blade matrix are adhesively connected to form an integrated structure. Wires of the semiconductor chilling plates are embedded into the heat conduction alloy ring. The heat conduction alloy ring is provided with a key groove for power source guidance. The wood cutting saw blade has the advantages that heat on the sawteeth is absorbed through semiconductors, no radiating grooves need to be formed in the thin sawtooth portions, and fluctuations caused by air cooling on the sawteeth can be omitted.
Description
Technical field
The invention belongs to timber processing sets up field, particularly timber cast-cutting saw slice.
Background technology
Hard alloy saw blade is made up of saw bit matrix and the carbide bit be embedded on circumference uniform distribution sawtooth, be widely used in the industries such as road construction, household decoration, machining, be mainly used to the materials such as cutting cement road, stone material, timber, plastic-steel section bar, aluminium section bar, iron and steel, the huge market demand.But existing hard alloy saw blade is in cutting timber operation process, owing to working continuously, remaining in wooden slag on saw blade and wood chip saw blade, that matrix is dispelled the heat is slow, easily generates heat, causes saw blade to be out of shape, affect cutting accuracy, reduction of service life.Now for the heat radiation of saw blade, common way adopts cold wind to lower the temperature to saw blade, but the machined surface using cold wind directly to blow saw blade easily causes wood chip to float in the air, and makes wood chip be scattered in around cutting machine, causes wood chip to be not easy to cleaning; Air-cooled effect also may cause saw blade to fluctuate, and sawtooth occurs bending, affects processing effect.
Summary of the invention
The object of this invention is to provide one be convenient to cutting timber time, the cast-cutting saw slice of good heat dissipation effect.
To achieve these goals, timber cast-cutting saw slice provided by the invention, comprise saw bit matrix, the center of described saw bit matrix is provided with the fixing hole being used for fixing saw blade, sawtooth is evenly distributed with around saw bit matrix, the fixing hole of described saw bit matrix is outside equipped with at least one semiconductor chilling plate, the cold junction of described semiconductor chilling plate is towards sawtooth, saw bit matrix is embedded with the heat conductor be connected with cold junction, conductor distance sawtooth root 10 ~ 15mm, described fixing hole is made up of a circle conducting alloy ring, conducting alloy ring formation integrative-structure bonding with saw bit matrix, semiconductor chilling plate wire is embedded in conducting alloy ring, conducting alloy ring is provided with the keyway guided for power supply.
The timber cast-cutting saw slice of this programme when in use, is fixed in and has on the rotating shaft of electric energy transmitting; When in cast-cutting saw slice high-speed rotation process, be energized to semiconductor chilling plate, the cold junction of semiconductor chilling plate is near sawtooth, and cold junction will absorb the heat of saw cut timber generation, and the heat in semiconductor hot junction is distributed by conducting alloy ring.
The invention has the advantages that: by semiconductor to the heat absorption on sawtooth is fallen, like this without the need to offering radiating groove in thinner serrated portion, also can save and using the air-cooled fluctuation that sawtooth is produced; Needed to carry out perforate to saw bit matrix before saw bit matrix embeds heat conductor, because heat conductor and saw bit matrix belong to different material, saw bit matrix can rely on heat conductor to eliminate stress.
As preferred scheme, described semiconductor chilling plate is provided with six, and is distributed on the saw bit matrix at fixing hole place; Its objective is in order under the intensity prerequisite ensureing saw bit matrix, dispelling the heat for saw blade of maximum efficiency.
As preferred scheme, described conducting alloy ring is provided with multiple louvre; If when cutting machine having radiator fan, coordinate louvre, can fast the heat of conducting alloy ring be taken away.Make semiconductor chilling plate can have good refrigeration.
As preferred scheme, described heat conductor is T-shaped structure, and it is curved that bending place is arranged arc-shaped transition.Widened the embedding area of heat conductor by T-type structure, can dispel the heat to more sawtooth.
Finally, described saw bit matrix fixing hole place is provided with the connecting axle of reinforcement; Because semiconductor chilling plate setting position is near fixing hole, ensure bonding strength by the connecting axle strengthened.
