Abstract
A guide for use in feeding metal bars to a machine tool comprises a plurality of side-by-side units (11) mounted on a drum (21) and each consisting of two equal and substantially semi-circular parts (12, 13), fixed and movable respectively, provision also being made for control means operatively connected to the movable part (13). The parts (12, 13) are each restrained at their own opposite ends, which are provided with stops, to respective rods (17) mounted on a bearing structure (18) fixed to the drum (21). Between the fixed and mobile parts there act one or more springs which thrust the movable part against the fixed part in the guide closure position.
Claims13
A guide for use in a machine tool bar feeding mechanism of the type having a drum and a plurality of axially spaced bearing structures secured on said drum, comprising
- a plurality of rods supported intermediate their ends on said structures parallel to the axis of said drum,
- a plurality of side-by-side units mounted on said drum and each consisting of two equal and substantially semi-circular parts, one part of each of said units being fixed and the other being movable relative to said drum,
- control means connected to the movable part of each of said units and operable selectively to grip a metal bar in said units, and
- means connecting the opposite ends of each of said parts to a pair of said parallel rods that are held by said structures in predetermined spaced relation to each other, thereby to restrain movement of said opposite ends toward each other.
A guide apparatus for use in the feeding of metal bars to a machine tool, comprising
- a drum,
- a bearing structure fixed on said drum and supporting thereon at least three parallel rods,
- a plurality of substantially semicircular, alternating fixed and movable parts,
- respectively, mounted on said drum, and
- means connecting the parts each at one end in staggered relation one with respect to the next to a single one of said three rods, and connecting the opposite ends of adjacent ones of said parts each to a different one of the others of said three rods.
