| 定尺黑皮管坯首先在定心孔鉆床上加工定心孔,然后在短尺剝皮機(jī)床上進(jìn)行表面剝皮加工,剝皮后成為表面合格的光亮坯。所有光亮定尺管坯由過(guò)跨平車(chē)和吊車(chē)送到短面加工機(jī)床處。由斷面加工機(jī)床對(duì)管坯的一段進(jìn)行加工,包括銑斷面、外圓倒棱,此處端面加工除滿足擠壓工序的要求外,還必須滿足鉆孔對(duì)端面密封的要求。一端端面加工的坯料再吊運(yùn)到深孔鉆床進(jìn)行鉆孔。鉆孔尺寸及端面質(zhì)量要滿足擠壓機(jī)對(duì)坯料的要求。坯料鉆孔后再進(jìn)行另一端端面加工,包括銑短面、內(nèi)孔車(chē)錐形口、以滿足擴(kuò)孔及擠壓的要求。 |

| First, center hole machining on the scaled raw tube billet is with a centering hole drilling machine, then scalping machining is with a short scale scalping machine, consequently it becomes a bright billet. All the bright tube billets are sent to section machining across the flat wagon and crane. Section machining includes section milling and outer chamfering and rounding. Besides, these face machining should meet not only the requirement of extruding process, but also the requirement of face seal. After single end-face processing, these tube billets are lifted for the deep hole drilling. Hole’s size and quality should meet the requirements of extruding process for billet. After that, the other end-face is machined, it includes section milling, and inner hole should be conical-mouthed machining, for meeting the requirement of expanding and extruding process. |
