Description

Saw web of wood saw

The utility model relates to a kind of saw blade, particularly a kind of wood saw saw blade that changes the sawtooth bending angle that utilizes, and it is not to be arranged on the same straight line at the sawtooth land tip that is positioned at saw blade plate body phase the same side, so that sawing timber better.

As shown in Figure 1, 2, 3, first kind of saw blade 1 of wood saw in the past, be to be formed with most sawtooth 11 in the bottom of saw blade plate body 10, these sawtooth 11 are to be arranged in saw blade plate body 10 both sides alternately, and the sawtooth 11 land tips 12 that are positioned at saw blade plate body 10 phase the same sides all are fitly to be arranged on the identical straight line.

Shown in Fig. 4,5,6, second kind of saw blade 2 of wood saw in the past, also be to be formed with most sawtooth 21 in the bottom of saw blade plate body 20, these sawtooth 21 be interlock be arranged in saw blade plate body 20 both sides, and the sawtooth 21 land tips 22 that are positioned at saw blade plate body 20 phase the same sides all are fitly to be arranged on the identical straight line, and are just different at the shape and the saw blade 1 at land tip 22.

Above-mentioned two kinds in the past saw blade 1,2 all be to arrange land tip 11,12 in good order, mainly be the idea that the producer generally has a kind of mistake, think and arrange neatly more with land is most advanced and sophisticated that the expression quality is good more, just in time opposite in fact.If it is the point of a knife of a cutter that each land is used as, sawtooth land tip, the straight both sides of proper alignment on saw blade then, good such as repeating two tool marks of scribing on timber with cutter, this all is to make lost work in fact, because have only first cutter the most effective, again repeatedly,, just increase the friction of the edge of a knife and timber on repeating to draw because of the fiber in the middle of two tool marks does not come off as yet backward.

As Fig. 7, shown in 8, with saw blade 1 in the past, 2, during sawing timber, on the timber by saw blade plate body 10, two gang saw teeth 11 of 20 both sides, 21 land tips 12, the residual timber 13 of 22 cut staples, 23, in fact also be bonded on the fiber of bottom more and can't come off, also can't be taken out of, and cause the saw saw not go down, this can influence the follow-up sawing effect of saw, because, land tip 12,22 are located along the same line, equal to draw the number cuttves heavily covering on the same tool marks, first cutter is effective, and second, the 3rd ... equal repeating to draw the number cutter on the same tool marks, first cutter is effective, second cutter, the 3rd cutter ... to be more and more invalid, and resistance be increasing.This phenomenon is more obvious on hard wood, because hard more timber, the mutual adhesion of fiber is big more, and this phenomenon, just land is ground very sharp keen at last, also can't be improved.

Shown in Fig. 9,10, the third is the sawtooth 31,32 of saw blade 3 with two kinds of shapes in the past; Wherein, sawtooth 31 has the land of forward chamfering tip 33 is arranged, and sawtooth 32 then grinds to form the land tip 34 with reverse chamfering, makes sawtooth blade tip end 34 than the most advanced and sophisticated 33 deflection saw blade plate bodys of land 35 center lines, and land tip 34 is just mixed and is clipped between the land tip 33, and number is less.

As shown in figure 11, though this saw blade 3 can be with land tip 34, the residual timber that is cut off fiber is cleared the timber bottom by force, but shape, the angle of reverse chamfering, and be not suitable for hook from the residual timber that cuts off fiber, and most advanced and sophisticated 34 right sides 37 of land do not possess sharp keen angle, the effect that only has removing, do not have hook from effect, residual timber still connects with the timber bottom, making exerts oneself must increase.Sawtooth 32 is that wood chip is provided with and the number of teeth ratio of normal sawtooth 31 is 8:2 in order to remove specially, and the wood chip that makes removing easily is accumulated in 32 on sawtooth 31 and sawtooth, forms the inhomogeneous wood chip of taking out of, increases the difficulty of removing wood chip.In addition, as increasing the number that land tip 34 has the sawtooth 32 of reverse chamfering, then normal sawtooth 31 numbers will reduce, and make the cut-out power of saw weaken.

At the shortcoming of wood saw zigzag fashion and arrangement mode in the past, main purpose of the present utility model is to utilize the method that changes the sawtooth bending angle, provides a kind of saw blade of wood saw of laborsaving, good sawing to make saw blade can have the effect of easy sawing, laborsaving operation.

Of the present utility model being characterised in that: be arranged in the sawtooth of phase the same side, saw blade plate body bottom, because the bending angle difference of sawtooth makes that the land tip is not to be arranged on the same straight line.

Laborsaving, good sawing and manufacturing easily when effect of the present utility model is the use of this saw blade.

Below in conjunction with two preferred embodiments and accompanying drawing the utility model is described in further detail.
