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 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.
结果表明:烧结体的镦粗变形规律与致密体相同。指出了曲柄压力机是粉末锻造工艺的最佳设备。
The results show that the upsetting deformation law of sintered preform is alike with the compact body, and the crank press is the best equipment of powder forging technology.
