1. Common specifications of the company: the width of the conventional light pole is 0.85 meters, 1.25 meters and 1.5 meters, and the thickness is 2.75mm, 3.0mm, 3.5mm and 3.75mm.Serial number, name, thickness, material utilization ratio of materials for production, ideal plate, note: 16 m light pole 2.751250/489.27m light pole 3.01250/496 %1200/4 38 m light pole 3.1270/4 410 m light pole 3.751500/4100%1522/4 512 m light pole 3.The utilization rate of 6-12 meters is calculated as follows: (1) known that the upper mouth of the light pole =60 taper =11‰ L=6000 choose the width of 1.25 meters steel plate material;Obtained: opening size: upper opening size =174 lower opening size =387. According to the opening size, 4 pieces can be opened.
Weight of 4 steel plates =7.85×0.275×112.2×600= 145.33kg (2) 1.25m steel plate weight =7.85×0.275×125×600= 161.9kg (3) material utilization rate =145.33/161.9×100%=89.77%7 m light pole :(1) known that the upper mouth of the light pole = 60 taper =11‰ =3.0 L=7000 choose the width of 1.25 m steel plate material;Obtained: opening size: upper opening size =179 lower opening size =421. According to the opening size, 4 pieces can be opened.
Weight of 4 steel plates =7.85×0.3×120×700=197.82Kg (2) 1.25m steel plate weight =7.85×0.3×125×700=206.06Kg (3) material utilization rate =197.82/206.06×100%=96%8 m light pole :(1) known that the upper mouth of the light pole = 60 taper =11‰ =3.0 L=8000 choose the width of 1.25 m steel plate material;Obtained: opening size: upper opening size =179 lower opening size =456. According to the opening size, 4 pieces can be opened.
Weight of 4 steel plates =7.85×0.3×127×800=239.27Kg (2) 1.25m steel plate weight =7.85×0.3×125×800= 235.5kg (3) material utilization rate =239.27/235.5×100%=101% 10m light pole :(1) known that the upper mouth of the light pole = 70 taper =11‰ = 3.75l =10000 choose the width of 1.5m steel plate material;Obtained: opening size: upper opening size =208 lower opening size =553. According to the opening size, 4 pieces can be opened.
1. The weight of 5 meters of steel plate used up =7.85×0.375×150×1000= 441.56kg (3) the utilization rate of materials =448.04/441.56×100%=101% 12m light pole :(1) known that the upper mouth of the light pole = 70 taper =11‰ L=12000 choose the width of 0.85m steel plate material;Obtained: opening size: upper opening size =208 lower opening size =624. 2 pieces can be opened according to the opening size.
The weight of 2 steel plates =7.85×0.375×83.2×1200= 293.9kg (2) 0.85m steel plates =7.85×0.375×85×1200= 300.26kg (3) material utilization rate =293.9/300.26×100%=97.88%
