“充液拉伸“是一种新的拉伸工艺,它首先是西德开始搞的。根据洋为中用的方针,为满足生产上的需要,我们本着自力更生的精神,在我厂十一车间开展了这项工艺的试验工作,并取得了一定的效果。在生产上得到了运用,并打算今后进一步扩大这项工艺的使用范围。一、成品零件的形状及要求成品零件的形状如图1所示,材料为1.2毫米厚的1 Crl8Ni 9 Ti不锈钢板,零件外表面的光洁度要求抛光至▽7～▽9,必须保证拉伸件外表面光洁无痕迹。
“Liquid-filled stretch” is a new stretch process, which first started with West Germany. In accordance with the principle of using foreign products for the purpose of production, in line with the spirit of self-reliance, we carried out experimental work on this process in our 11th workshop and achieved certain results. In the production has been applied, and intends to further expand the scope of the use of the process. First, the finished part shape and requirements Finished part shape shown in Figure 1, the material is 1.2 mm thick 1 Crl8Ni 9 Ti stainless steel plate, the outer surface of the parts finish polished to ▽ 7 ~ ▽ 9, must ensure that the tensile member Smooth appearance without traces.
