Intensity.
Produce this longeron of the present invention only need to develop two kinds of small-sized extrusion dies, simultaneously extruder tonnage do not need very big
(extruder tonnage is less than 90MN), extruding expense is very low.Mold developing expense does not count, and only extruding expense and machine add
Two just can be reduced a bulk of cost.First generation car longeron extruding expense is (a computational back-end longeron cost)：11m×
32.153Kg/m × 9.5 yuan/Kg=3360 unit, machine adds expense：3 hours × 300 yuan/hour=900 yuan, car load longeron (two pieces/
Platform) back segment cost=(3360+900) × 2=8520 unit；And a new generation's longeron extruding pressure expense is that (a computational back-end longeron becomes
This)：A section：10m × 22.924Kg/m × 5.8 yuan/Kg=1329.59 unit, B section 4.86m × 16.779Kg/m × 5.8 yuan/Kg=
472.97 first machine adds expense：* 150 yuan/hours=300 yuan of B section 2 hours, car load longeron back segment cost=(1329.59+472.97
+ 300) * 2=4205.12 unit.The every chassis of only this item can 4314.88 yuan of reduces cost, can obtain by annual 2000 Production rate
862.896 ten thousand yuan of net profit.
Because automobile making makes automobile gross mass mitigate using aluminium alloy in a large number, thus reducing the consumption of fuel oil；Due to
Oil consumption is low, the waste gas discharge of light weight, automobile is just few, and pollution level just declines；The response rate of junked-auto is high, aluminum automobile zero
Part is substantially all recyclable；Required for reclaiming, the energy is few, and aluminum can multiple circular regeneration.According to relevant information, automobile
Weight often mitigates 10%, at most can achieve fuel-economizing 8%.Often using 1kg aluminum, automobile can be made to reduce 20kg tail gas row in lifetime
Put.Meanwhile, aluminum is green material, easily reclaims, recovery capable of circulation.It is to produce used by this part using the energy that aluminum is saved
6-12 times of primary aluminum power consumption.In aluminum alloy vehicular application aspect or stage at the early-stage, full aluminum loading haulage vehicle is also for China
Do not form high volume product.China Logistics equipment semitrailer is in seriously delayed state now, and the developed country such as America and Europe is wide already
The aluminum alloy bodywork semitrailer of general use.The appearance of this little gooseneck type Combination Welding longeron will expand full aluminum further and close
The commonly using of golden semitrailer.
Finally illustrate, preferred embodiment above only in order to technical scheme to be described and unrestricted, although logical
Cross above preferred embodiment the present invention to be described in detail, it is to be understood by those skilled in the art that can be
In form and various changes are made to it, without departing from claims of the present invention limited range in details.
