Process for loading a lathe with bars to be machined and loading device for carrying out of the process

摘要

A process for loading a lathe in which a new bar to be machined is introduced laterally into a guide-bar device in form of a tube during the machining of a last piece at the end of a preceding bar. The new bar causes the ejection of the remnant of the preceding bar by pushing against the rear of the preceding bar. A device for loading a lathe with bars to be machined comprises a guide-bar device in form of a tube having two parts which can be opened for laterally introducing a new bar to be machined into the tube. The bar in the tube is fed by a hydraulically controlled push-piston. Pressure pistons press the two parts of the tube against each other in order to ensure a fluid tight seal. Return pistons are utilized radially move the upper part of the tube at the time of loading.
