Abstract
The utility model relates to a circular saw blade for cutting wood, in particular to a hard alloy circular saw blade. The circular saw blade is characterized in that the saw blade body is a large and thin disc, a center hole is formed at the center of the saw blade body, driving holes are formed at the periphery of the center hole, a process hole is formed in the middle position of the radius of the saw blade body, saw teeth are distributed on the outer circumference of the saw blade body, a hard alloy cutting head is welded on the outer circumference of the saw teeth, a sawdust groove is formed between two adjacent saw teeth, and the saw teeth on the outer circumference of the saw blade body are arranged at nonuniform pitch. The hard alloy circular saw blade can greatly reduce noise when used for cutting wood, greatly lowers the ambient noise pollution, greatly improves the service life of the circular saw blade and enhances the cutting quality.
Description
Technical field:
The utility model relates to cutting timber saw blade, particularly a kind of sintered carbide circular saw.
Background technology:
Conventional sintered carbide circular saw is in cutting timber process, because the saw blade in use dissection between sawtooth and the timber is interrupted, regular, so saw blade is easy to generate resonance in cutting process, not only be easy to generate noise, but also can reduce the service life of saw blade.
The utility model content:
The purpose of this utility model is in order to solve carbide-tipped circular sawblade for wood working noise low problem in excessive and service life in use, distribute by changing sawtooth and provide a kind of, thereby change the intrinsic frequency of saw blade, reach and reduce the noise of saw blade in cutting process, and further improve the sintered carbide circular saw in the service life of saw blade.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of sintered carbide circular saw, comprise blade bodies, this blade bodies is a big and thin rosette, the center of blade bodies is provided with a centre bore, the centre bore periphery is provided with driving hole, blade bodies radius middle part is provided with fabrication hole, be distributed with sawtooth on the blade bodies excircle, be welded with carbide bit on the excircle of sawtooth, constitute chip pocket between adjacent two sawtooth, the sawtooth on the described blade bodies excircle is arranged by non-homogeneous rack saw.
Compared with prior art, the beneficial effects of the utility model are: can significantly reduce cutting timber sintered carbide circular saw generating noise in use, reduce the pollution of noise greatly to surrounding environment, and the service life of improving saw blade to a great extent, sawing quality improved.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: blade bodies 1, sawtooth 2, carbide bit 3 holds tip groove 4, centre bore 5, driving hole 6, fabrication hole 7.
The specific embodiment:
The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.
The sintered carbide circular saw that present embodiment provides, as shown in Figure 1, blade bodies 1 is a big and thin rosette, disk diameter is generally Φ 150mm～Φ 600mm; The center of blade bodies 1 is provided with a centre bore 5, and the aperture is generally Φ 15mm～Φ 30mm; Centre bore 5 peripheries have 2～6 driving holes 6, and driving hole 6 apertures are generally Φ 5mm～Φ 15mm, and driving hole 6 has provided four among the figure; In blade bodies 1 radius middle part 2～4 fabrication holes 7 are arranged, the aperture is generally Φ 13mm～Φ 25mm, and the fabrication hole 7 that provides among the figure is two.Be distributed with sawtooth 2 on blade bodies 1 excircle, be welded with carbide bit 3 on the excircle of sawtooth 2, the shape and the quantity of sawtooth 2 and cutter head 3 are decided according to cutting material and purposes, constitute chip pocket 4 between adjacent two sawtooth.Sawtooth 2 on described blade bodies 1 excircle arranges that by non-homogeneous rack saw in Fig. 1: the spacing of sawtooth 2-1 and sawtooth 2-2 is less than the spacing of sawtooth 2-2 and sawtooth 2-3.
Non-even teeth is directly installed on the saw that cuts timber apart from sintered carbide circular saw and uses, and installs the back saw and drives the sawing task that saw blade rotates, various timber are finished in feeding.The mode of feeding can be that swing type also can be the horizontal sliding mode.
