Preferably, above-mentioned self material of notch cuttype stave workpieces is core axle.
The utility model provide notch cuttype lath, its cross section include the first inclined plane, the second inclined plane, 3rd inclined plane, the 4th inclined plane, the first plane, the second plane, the 3rd plane and fourth plane, its In, described first plane, described second plane, described 3rd plane are parallel with described fourth plane, institute Stating fourth plane is bottom surface, and when described fourth plane is horizontal plane, one end of described first inclined plane is even Extend obliquely and with described in connecing one end of described fourth plane, and the other end of described first inclined plane One end of first plane connects, and one end of described second inclined plane connects the other end of described first plane, And extend obliquely in the other end of described second inclined plane and be connected with one end of described second plane, institute The one end stating the 3rd inclined plane connects the other end of described second plane, and another of described 3rd inclined plane End is outer to be extended obliquely and is connected with one end of described 3rd plane, and one end of described 4th inclined plane connects Extend obliquely and with described outside the other end of described 3rd plane, and the other end of described 4th inclined plane The other end of fourth plane connects.
The shape of the notch cuttype lath that the utility model provides is different from traditional square lath, by changing The shape of the lath obtained is to improve volume recovery.
As a example by raw material wood mandrel radius is as 19.5mm, its maximum squared timber that can prepare transversal The a length of 23mm in face, width is 14.7mm, the size of its maximum notch cuttype lath 8 that can prepare For, the within angle of the first inclined plane 1 and the first plane 5 is 101 °, the second inclined plane 2 and the second plane The within angle of 6 is 101 °, and the within angle of the 3rd inclined plane 3 and the second plane 6 is 101, and the 4th tilts The within angle of face 4 and the 3rd plane 7 is 101 °, and the width of the second plane 5 is 23mm, fourth plane Width be 37mm, the vertical plane standoff height of the first inclined plane 1 is 7.3mm, the second inclined plane 2 Vertical plane standoff height be 7.4mm.
The volume recovery of two kinds of saw lumber modes can be calculated by following formula:
X1=S1/S
X2=S2/S
In formula: X1Traditional square saw lumber mode volume recovery (%)
X2Novel stairstepping saw lumber mode volume recovery (%)
S wood spool circular cross-sectional area (mm2)
S1Traditional square saw lumber mode cross-sectional area (mm2)
S2Novel stairstepping saw lumber mode cross-sectional area (mm2)
The area of wood spool circular cross section is calculated by following formula
S=π r2=3.14 × 19.52≈1194(mm2)
In formula: r wood spool rounded cross section radius surface (mm)
The area of traditional square saw lumber mode cross section is calculated by following formula
S1=2l w=2 × 23 × 14.7 ≈ 676 (mm2)
In formula: l traditional square saw lumber mode cross-section lengths (mm)
W traditional square saw lumber mode cross-sectional width (mm)
The area of novel stairstepping saw lumber mode cross section is calculated by following formula
S2=2 (T1+T2)
In formula: T1Novel stairstepping saw lumber mode cross section top half trapezoidal area (mm2)
T2Novel stairstepping saw lumber mode cross section the latter half trapezoidal area (mm2)
Can calculate according to each several part size
T1=7.4 × tan (101 °-90 °) × 7.4+23 × 7.4 ≈ 181 (mm2)
T2=37 × 7.3-7.3 × tan (101 °-90 °) × 7.3 ≈ 260 (mm2)
Numerical value is substituted into novel stairstepping saw lumber mode cross-sectional area computing formula
S2=2 (T1+T2) ≈ 2 × (181+260)=882 (mm2)
Therefore the volume recovery of two kinds of saw lumber modes is as follows
X1=S1/ S ≈ 676/1194 ≈ 56.62%
X2=S2/ S ≈ 882/1194 ≈ 73.87%
Calculating according to the lath producing 1 ten thousand stere, the wood spool volume of timber that need to consume is calculated by following formula
V1=10000/X1≈10000/0.5662≈17661.6(m3)
V2=10000/X2≈10000/0.7387≈13537.3(m3)
In formula: V1Traditional square saw lumber mode produces the wood spool volume of timber (m needed for 1 ten thousand stere lath3)
V2Novel stairstepping saw lumber mode produces the wood spool volume of timber (m needed for 1 ten thousand stere lath3)
By calculating it can be seen that the volume recovery obtaining the notch cuttype lath that the utility model provides is 73.87%, the volume recovery of traditional square saw lumber mode is 56.62%, and volume recovery improves 17.25%, novel The volume recovery of stairstepping saw lumber mode is 1.3 times of the volume recovery of traditional square saw lumber mode.According to producing 1 The lath of ten thousand stere calculates, and traditional square saw lumber mode need to consume the wood spool volume of timber about 1.8 ten thousand stere, Novel stairstepping saw lumber mode need to consume the wood spool volume of timber about 1.4 ten thousand stere, novel stairstepping saw lumber mode Saving is become a useful person consumption about 0.4 ten thousand stere, with the 650 yuan of calculating of every cubic metre of poplar log price, saves Cost 2,600,000 yuan.
