APPARATUS FOR FEEDING BARS OR THE LIKE IN MACHINE TOOLS

摘要

Apparatus for feeding bars in machine tools has a cylindrical housing for a group of parallel cylindrical guides which are rotatable in the housing as a unit to place a selected guide into a feeding position in which a workpiece which is inserted into the selected guide can be fed lengthwise to enter a machine tool. The group of guides is surrounded by a jacket consisting of soundproofing material and the guides are disposed in pairs with the guides of each pair located diametrically opposite each other with reference to the axis of the housing and having different internal diameters. The advancing mechanism for moving a bar in the selected guide lengthwise has a pusher which is introduced into the selected guide behind an inserted bar and is urged forwardly by a cable which is connected to a weight.
