Embodiment 8-14
The buck saw of embodiment 8-14, its saw blade parameter is corresponding on the basis of embodiment 1-7 respectively, and to change parallel portion 82 width c be 10mm.
The saw blade of above-described embodiment 1-14 and following comparative example 1-7 is carried out respectively to amount of bow determination test under the same conditions, assay method is as follows: as shown in Figure 8, saw blade horizontal positioned, two ends are fixed, to the load that its gold 2 centers apply straight down, size is 9.8N, measure the maximum deflection amount of platform gold 2 in respective direction.Amount of bow computing formula: amount of bow δ=(W*L
3)/(192*E*I), wherein, W: load, L: length of saw blade, E: Young's modulus, I: section second moment.
Comparative example 1-7: as shown in Fig. 5-7, a kind of buck saw, corresponding one by one with embodiment 1-7, and difference separately is all: saw blade platform gold 2 along its length optional position has identical section 8, and section 8 entirety are rectangular, the thickness of the each position of platform gold broad ways is identical.Meanwhile, comparative example 1-7 and embodiment 8-14 are also identical corresponding relations.Design parameter is in table 1.
Table 1
When 1 gold of the utility model buck saw saw blade uses the steel same with comparative example saw blade platform metallographic, Young's modulus is identical, but due to section configuration difference, therefore the value of section second moment can be variant, and concrete measurement result is as shown in Fig. 9-10.As shown in Figure 9, the amount of bow of the utility model embodiment 1-7 saw blade all reduces with respect to each self-corresponding comparative example, and at least, within the scope of platform gold thickness 0.4-1.0mm, the amount of bow of the utility model saw blade 1 is on the whole less than comparative example saw blade amount of bow.As shown in Figure 10, in the utility model embodiment 8-14, the amount of bow B of buck saw saw blade reduces with respect to the amount of bow A of corresponding buck saw saw blade in embodiment 1-7 arbitrarily, therefore, known in conjunction with Fig. 9-10, the amount of bow of the utility model embodiment 8-14 saw blade also all reduces with respect to each self-corresponding comparative example, and at least, within the scope of platform gold thickness 0.4-1.0mm, the amount of bow of the utility model saw blade 1 is on the whole less than comparative example saw blade amount of bow.Its rigidity of saw blade platform gold therefore with certain gradient is better than the saw blade platform gold of consistency of thickness, the stability can greatly improve the cutting of buck saw saw blade time.
Comparative example 1-7 saw blade is that embodiment 1-7 compares as shown in figure 11 with the rigidity of comparative example 1-7 with the amount of bow ratio of corresponding saw blade in embodiment 1-7.Visible, within the scope of platform gold thickness 0.4-1.0mm, 1 golden rigidity of the utility model saw blade be 1.5 times of comparative example and more than, and increase along with reducing of platform gold thickness a.In the time that the platform Buddha's warrior attendant of embodiment 6 saw blades 1 is just in time 1.5 times of comparative example 6 saw blade platform Buddha's warrior attendants, the relation of platform gold thickness a and parallel portion 82 thickness d can be reduced to:
Figure 12 is the partial enlarged drawing of Fig. 9, and as shown in figure 12, the utility model saw blade 1 can obtain the rigidity identical with comparative example by the platform gold thinner with respect to comparative example, and therefore yield rate is also higher.For example, for obtaining and comparative example saw blade identical rigidity when the platform gold thickness 0.9mm, the golden thickness a of platform of the utility model saw blade 1 can be thinned to 0.77mm, and being also that sword is thick can be thinned to 1.2mm from 1.4mm.
As shown in Figure 10, within the scope of platform gold thickness 0.4-1.0mm, in embodiment 8-14, the amount of bow B of buck saw saw blade reduces with respect to the amount of bow A of corresponding buck saw saw blade in embodiment 1-7 arbitrarily, therefore calculate rigidity increment rate according to following formula: rigidity increment rate (%)=[(A-B)/A] × 100, thus obtain the curve shown in Figure 13.As shown in Figure 13, rigidity increment rate increases along with reducing of a, and rigidity increment rate is maximum in the time of a=0.4mm, is 7%.It should be noted that in addition, although only listed parallel portion width c above and be taken as the embodiment 1-7 of 5mm and c and be taken as the embodiment 8-14 of 10mm, but inventor has carried out corresponding amount of bow to c at the corresponding saw blade of the scope of 5mm-10mm to be measured, result amount of bow is all to reduce along with the increase of a in the scope of a=0.4-1.0mm, and is less than all the time the amount of bow of corresponding saw blade in comparative example 1-7.
Be enlightenment according to desirable embodiment of the present utility model above, by above-mentioned description, related personnel can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to claim scope.
