摘要

Remote-controlled machine for lining the end of heat exchanger tubes (13) crimped in a tubular plate (14) with a sleeve, comprising a hose (15) connecting a push/pull device to a motorised unit (16) driving tools for fastening the sleeve, a tool loader (25, 26) at the end of a cable (20) driven by the push/pull device, and means for bringing the end of the hose opposite the end of each tube. The motorised unit (16) comprises two superposed splined hubs (30, 33), one of which is driven by a low-speed electric motor and the other by a high-speed pneumatic motor. ……
