我们在用应变法测定橡胶密封件径向应力过程中,碰到一种薄壁筒零件的加工。这个零件最薄处的壁厚仅为0.09mm(见图1),零件材料为3Cr13。经多次试验加工,获得了成功,质量完全合格。薄壁筒零件试制工艺路线如下:毛坯退火——粗车——退火——精车。粗车工艺要点:内、外圆,端面,肩面均留单面余量0.8～1mm;钻φ5孔:留夹头长～35mm。精车工艺要点(见图2):车去氧化皮;加工出R2.5槽;内、外圆,端面,肩面均留单面余量0.3mm;
We are in the process of measuring the radial strain of a rubber seal with a strain of thin-walled tubular parts. The thickest part of this part of the wall thickness of only 0.09mm (see Figure 1), parts material 3Cr13. After many trials and processing, has been successful, the quality of fully qualified. Thin-walled parts trial production process routes are as follows: Blank annealing - roughing - annealing - fine car. Rough car technology points: inside, outside, face, shoulder surface left single side balance 0.8 ~ 1mm; drill φ5 hole: stay chuck length ~ 35mm. Fine car technology points (see Figure 2): car to the oxide skin; processed R2.5 slot; inside and outside the cylinder, the end surface, shoulder surface left single side margin 0.3mm;
