Experiments show that, in applying the correct mold structure and appropriate process conditions, when the temperature at 350 ° C billets around Rafah Deep Mold temperature at 350 ° C and about good lubrication circumstances, can be successful in stamping on the crank press to produce magnesium phone alloy shell.

实验表明，在应用正确的模具结构和适当的工艺条件下，当坯料温度在350℃左右，拉深凹模温度在350℃左右和良好润滑情况下，能够成功地在曲柄压力机上冲压生产出镁合金手机外壳。用英文翻译一下哦！！！！！！！！！谢谢！！！！！！！！

The upsetting test of metal powder sintered preform by blow speed of the hydraulic press,crank press,pneumatic hammer and high energy rate forging hammer was reported.

研究了用液压机、曲柄压力机、空气锤及高速锤的打击速度对粉末冶金烧结体进行的镦粗试验。

The multi- connecting rods press is one kind new press which taking the multi- linkmotion gear as the operating mechanism.The slide has the obviously comes back promptly kinematics the characteristic.In work sector,The slide"s speed is steady, and is lower than the crank press greatly, this is advantageous to enhance quality of the big distorts stretch. At the same time it reduces the impact between the molds and lengthen the mold"s service life.

多连杆压力机是一种以多连杆机构为工作机构的新型压力机，滑块具有明显的急回运动特性，在工作区间，滑块速度平稳，并且大大低于曲柄压力机，这有利于提高变形较大的拉伸件的质量，同时减少模具间的冲击，延长模具使用寿命。

Through analyzing the result, we can draw a conclusion that it is an effective way to increase the thickness of crank web than to increase the shaft diameter by the way which improves the rounded stress of the crankshaft from structural.

通过对计算结果的分析，得出在结构上改善曲轴过渡圆角处应力集中时，增加曲柄臂厚度与增加轴颈直径是较有效的方法，为某增压发动机曲轴的结构设计提供了理论依据。

AVL BRICKS software is used for torsional vibration calculation of the crankshaft if increasing the crank web radius but keeping the radius of conrod and main journal, which can reach the high performance.

利用AVL的BRICKS软件对曲柄半径加大而连杆及主轴颈半径均未改变的曲轴进行了扭振计算，以确保曲轴能够满足较高性能的要求。
