摘要
利用特制的双行程液压缸为动力 ,在无缝管三辊联合穿轧生产过程可实现抱杆、抱管和打开三个动作 ,完全保证了钢管穿轧过程的轴向抛出管的配合要求。该项技术已在生产实际中稳定运行五年之久 。
The clamping centering device can realize three movement, namely, to clamp mandrel bar, to clamp semifinished tube and to open clamping centering rolls after three rolls piercing & rolling combined process by special hydraulic cylinder of twin-travel. It can pledge completely the requirement to shoot out axially tube after the piercing & rolling combined process. This technology has steady run for five years more in practical production process. It may generalize and apply in correlative assembly.
