Abstract
The utility model discloses a circular saw blade for woodworking. The circular saw blade for woodworking comprises a saw plate, saw teeth, a teeth-cutter on the saw teeth, a heat dissipation groove arranged in the saw plate and an axle hole arranged in the center of the saw plate, wherein an inner groove and an outer groove are also arranged in the saw plate, and a long blade is arranged at one side of the outer groove and the inner groove. The circular saw blade for woodworking has a reasonable structure, and the saw plate can be effectively avoided being contacted with wood to generate friction, which is beneficial to dissipating heat of the saw blade and protecting the saw blade.
Description
Technical field
The utility model relates to a kind of metal saw blade, more particularly, relates to a kind of circular saw blade for wood that is used for Wood Processing.
Background technology
Circular saw blade for wood is through rotating at a high speed to reach the purpose of cutting timber.In cutting process,, not only produced great amount of heat, made the temperature fast rise because the saw blade surface acutely rubs with timber; Influence the mechanical property of saw blade itself; Make the saw bit matrix expanded by heating especially, aggravated the frictional resistance with timber, also increased the power of motor; Reduce rotating speed, directly had influence on the working (machining) efficiency of timber.Like Fig. 1; For saw blade is cooled, the center of the saw plate 1 of present round log saw blade is provided with axis hole 4, and axis hole 4 is provided with keyway 41 and is used for and the rotating shaft relative fixed; The saw blade periphery is along being provided with sawtooth 2; Serrated knife 21 is installed on the sawtooth 2, is provided with 4 radiating grooves 3 near the outside around the saw blade, said radiating groove 3 is mainly used in the saw blade heat radiation.Be installed in when carrying out sawing on the woodworking saw blade machine when several pieces saw blades are coaxial, saw blade and timber high-speed friction can produce heat, and long time continuous working makes the saw blade temperature higher, although the radiating groove heat radiation is arranged, but still can not fast heat be distributed, and are unfavorable for sawing timber.
The utility model content
To the deficiency of prior art, the utility model provides a kind of circular saw blade for wood rational in infrastructure, saw plate and timber contact friction in the time of effectively avoiding cutting.
For achieving the above object, the utility model is realized through following scheme:
Circular saw blade for wood comprises the serrated knife on saw plate, sawtooth, the sawtooth, also comprise the radiating groove that is arranged on the saw plate, be arranged on saw plate center axis hole, also be provided with water jacket and inside groove on the saw plate, be provided with long blade in a side of said water jacket and inside groove.
The thickness of said long blade is greater than the saw plate thickness and less than the thickness of serrated knife.
Said water jacket is arranged on a saw plate outer edge and an end opening, and said saw plate center is stretched in the other end of said water jacket.
Said inside groove points to said saw plate center and is provided with, and is positioned at the zone of saw plate middle part annulus.
The outer edge of said saw plate also is uniformly distributed with many radiating grooves, and said radiating groove one end opening is in the outer rim of plaque.
The axis hole at said saw plate center is provided with positioning spline.
The beneficial effect of the utility model is: interior water jacket is provided with long blade, and the thickness of this long blade is bigger than the saw plate thickness, when cutting timber, the timber cut surface is separated with the saw plate, has reduced large-area friction.This structure has reduced the power of motor that frictional resistance consumes on the one hand, thereby has increased rotating speed, and production efficiency is provided; Avoid long-term friction to make on the other hand and sawed the plate temperature distortion, prolonged the service life of saw blade; The structure of water jacket also helps the eliminating wood chip simultaneously.
Description of drawings
Fig. 1 is existing circular saw blade for wood structural representation;
Fig. 2 is the structural representation of the circular saw blade for wood of the utility model;
Fig. 3 is the local enlarged diagram of the long blade of the utility model circular saw blade for wood.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 2, a kind of circular saw blade for wood of the utility model comprises saw plate 1, sawtooth 2, radiating groove 3, and axis hole 4 also comprises water jacket 6, inside groove 5.
Sawtooth 2 evenly distributes and saws plate 1 outer marginal circumference, and serrated knife 21 is installed on the sawtooth 2.Two pairs of radiating grooves 3 are symmetricly set on saw plate 1 outer rim, and the quantity of radiating groove can also be provided with according to actual needs, and radiating groove 3 is a tiny fluting slit; When saw blade cutting timber; The saw plate produces a large amount of heats, causes that saw blade expands with heat and contract with cold and is out of shape, and the slit that radiating groove 3 is reserved makes when the saw plate is heated; Can there be enough spaces to allow Volume Changes, have avoided the drawback of saw plate 1 expanded by heating distortion.Axis hole 4 is positioned at the center of circle of saw blade, and a positioning spline 41 is arranged on the axis hole 4, is used to saw the installation and the location of plate.Like Fig. 2, shown in 3, also be provided with an a pair of inside groove and an external groove on the saw plate, inside groove and water jacket are rectangular waist shape; Phase person distributes alternately; Water jacket 6 one end openings are in saw plate outer rim, and a side of water jacket 6 is provided with long blade 51 and positioning step 52, and long blade 51 is arranged on the positioning step 52.Inside groove 5 is symmetrical waist shape for being arranged on the fluting of remaining silent on the saw plate 1, and inside groove comprises two positioning steps 52 and a long blade 51.Long blade 51 thickness are less than the thickness of sawtooth 2, greater than saw plate 1 thickness, and when saw blade was worked, long blade can make the timber cut surface keep separating with saw plate 1; Avoid large-area frictional heat to cause the saw blade surface to be heated; Protect saw blade, reduced frictional force simultaneously, reduced the power of motor; Increased rotating speed, made to help improving cutting timber efficient.It is identical with the effect on the inside groove 5 that long blade 51 is arranged on water jacket 6; Water jacket 6 all is that the angle that Off-Radial direction about 5 is spent is arranged on the saw plate 1 with inside groove 5; Water jacket is arranged on the cylindrical zone of saw plate about 1/3; Inside groove then is arranged in radially about 1/3 to 2/3 the circle ring area of saw plate, and promptly except that the position at saw plate center, all the other positions on the saw plate all are in the protection domain of long blade; Since the center from positioning spline closely, not yielding, so the central area need not be provided with the protection usefulness blade.Simultaneously, the hollow space of inside groove 5 and water jacket 6 can also work to discharge wood chip.
