Bar feeding apparatus for an automatic lathe.

摘要

A rod-supply arrangement is described, comprising a guide tube containing oil and mounted in a support and a feed rod movable axially in the guide tube and coupled to a feed drive, the forward end of the feed rod carrying a rotatable coupling element, and also with an oil-supply pipe and an oil-return pipe. In order to obtain such an arrangement which requires little space and has a substantially simplified charging of the guide tube with always a new rod of material, in connection with which the stocking of the rods of material is not restricted to a prescribed number of existing guide tubes, provision is made for the guide tube to consist of a guide channel formed in the support and coupled with at least one oil-supply pipe and of an upwardly swingable cover extending throughout the length of the guide channel, oil being supplied through the oil-supply pipe during the feeding of the material rod in the closed guide tube of the guide channel.
