Bar stock feeder method and apparatus

摘要

A bar stock feeder for feeding bar stock to a multiple spindle lathe is disclosed. The bar stock feeder has several guide tubes, each for holding a piece of stock. The tubes are flooded with hydraulic fluid to provide a film of fluid to support the pieces of stock. Each tube contains a piston for advancing the pieces of stock towards the lathe. The tubes have a pivoting part which allows the operator to separate the tubes for reloading. The pistons are retracted into the pivoting part of the tubes prior to separation such that they are not in the way during reloading.
