| 標(biāo)題 |
| 75 kg/m鋼軌12號(hào)可動(dòng)心軌轍叉單開道岔加工工藝研究(36 卷) |
| 英文標(biāo)題 |
| Study on the Processing Technology of No. 12 Simple 75kg/m Turnout with Movable-point Frog |
| 摘要 |
| 介紹了75 kg/m鋼軌12號(hào)可動(dòng)心軌轍叉單開道岔（SC381）的主要尺寸、技術(shù)參數(shù)和結(jié)構(gòu)特點(diǎn)。分析了長(zhǎng)心軌、跟端、模鍛翼軌和墊板件的加工工藝。由于采用數(shù)控機(jī)床完成一些工序的加工，提高了道岔產(chǎn)品的科技含量。 |
