  • FIGZB Josf Sfender- Robert
  • My present invention relates to metal-cutting apparatus and, more particularly, to an apparatus for trimming superfluous metal from castings or the like, e.g., of steel or iron, light metals such as aluminum and heavy metals such as die-cast zinc.
  • the blades used for this purpose may be analogous to sawblades, i.e., may have well-defined teeth similar to those of a milling cutter, or may be abrasive (e.g., diamond particle) disks with which material is removed with abrasive techniques.
  • the term cutting disk is used therefore to refer to both cutting blades of the tooth-type and abrasive-type cutting disks in which abrasive particles are bonded at least along the periphery of the disk.
  • Another object of the invention is to provide an apparatus of the class described with means limiting the effect of play and vibration and, therefore, reducing or obviating the disadvantages mentioned above.
  • Still another object of this invention is to provide an improved apparatus for the removal of superfluous material from metal castings which is more versatile and of simpler construction than earlier apparatus for the same purpose.
  • an apparatus which comprises a support structure, a workpiece carriage shiftable on this support structure, preferably in a horizontal plane and with respect to horizontally disposed guide surfaces, and a blade-carrying carriage slidably mounted on the support structure for movement perpendicular to the movement of the workpiece carriage but also in a horizontal plane and with respect to a horizontally disposed guide surface.
  • the blade-carrying carriage comprises a pivot (generally horizontal and parallel to the direction of movement of the workpiece and perpendicular to the direction of movement of the blade carriage) about which a blade-support arm is swingable; the latter arm overhang the workpiece support and is provided at its free end with a rotating blade lying in a plane parallel to the swing plane of the arm and perpendicular to the direction of displacement of the workpiece.
  • the play of the apparatus is taken up by at least one fluid-responsive stressing means interposed between one of the carriages and the respective guide surface and energizable during the severing operation to prevent play between this carriage and the support structure.
  • the play-eliminating, fluid-responsive means for stressing the carriage against the support structure comprises a guide channel in the carriage which is juxtaposed with the horizontal drive surface or ways of the support structure and is provided with a hydraulic cylinder whose piston or plunger is urged against the ways upon pressurization of the cylinder.
  • the guide channel, in which the ways or guide members are received may be undercut so that upon pressurization of the hydraulic cylinder, edges, ridges or other abutment surfaces of the carriage, oppose the cylinder arrangements, and are brought into tight contact with the guide surfaces.
  • the play-absorbing or eliminating means is provided at least for the workpiece carriage.
  • the arm carriage is shiftable horizontally in a direction perpendicular to the workpiece-support table or carriage and, therefore, parallel to the plane in which the arm is swingable.
  • the arm carriage may be provided with horizontal bores, preferably a pair of horizontally-spaced bores, lying in a horizontal plane perpendicular to the vertical plane of arm swing and equispaced on opposite sides of this vertical plane, the bores slidably receiving a pair of shafts or bars, of circular cross-section, constituting the ways or guide surfaces of the support structure along which the arm carriage is displaceable.
  • a pair of hydraulic cylinders is provided in the arm carriage on diametrically opposite sides of each of the shafts and are formed with pistons or plungers adapted to bear symmetrically thereon simultaneously to take up any play between these carriages and the support structure.
  • the workpiece-support table or carriage is provided with a workpiece holder orientatable about both a vertical axis, i.e., an axis parallel to the plane of swing of the blade arm and transverse to the direction of displacement of the workpiece table, and about a horizontal axis perpendicular to this vertical axis and lying either parallel to the direction of displacement of the workpiece table or transversely thereto.
  • the means and controls for displacing the movable portions of the holder should be disposed to either side of the blade position or upon the side of the holder remote from the blade carriage, thereby allowing accessability to all of the controls which may require adjustment. Furthermore, it has been found desirable to provide, upon the same movable workpiece carriage, or on the same ways, two or more workpiece holders which may be operated or positioned individually so that, during cutting with one holder, the other holder may be used to mount a workpiece and vice versa.
  • the blade lies in a vertical plane perpendicular to the pivot axis of the arm and is journaled at the free end of the latter. It has been found to be advantageous, especially when cuts are required through large cross-sections, to impart an oscillation to the blade-carrying arm in the longitudinal direction of the latter, i.e. radially with respect to the blade. This is effected in the system of the present invention by mounting the arm pivot in a horizontally reciprocatable bearing block and hydraulically or pneumatically displacing this block at a relatively high frequency (e.g. 60 cycles per sec to kc per sec).
  • a relatively high frequency e.g. 60 cycles per sec to kc per sec.
  • the fluid-responsive oscillating device may include a double-acting pressurizable cylinder, the opposite sides of which are pressurized through a reversible valve, or a single-acting cylinder working against a spring.
  • the control means may include a motor for oscillating the valve or any other reciprocating system conventional in the art.
  • the cutting movement of the arm is, of course, the swinging movement about its pivot axis and there is provided, in accordance with the present invention, a hydraulic cylinder which is pivotally mounted upon the blade carriage and is coupled with the arm for swinging the latter.
  • the arm is preferably also provided with a rearward extension, i.e. an extension in the direction away from the blade, which is provided with a counterweighting body, e.g., the drive motor for the blade.
  • the drive motor may be connected with the blade via a V- belt transmission and it has been found to be advantageous to provide means, e.g., telescoping parts or the like, for tensioning the V-belt or, in more general terms, adjusting the distance between the motor and the blade pulley.
  • a control panel or switching arrangement enabling convenient regulation of all of the functions of the apparatus.
  • FIG. 1 is a side-elevational view, partly in diagrammatic form, of an apparatus for the removal of deadheads and like superfluous metal structures from castings of various configurations in accordance with the present invention

  • a cutoff disk (blade) 4 which is partly enclosed by a head 30, carried by the arm 3a, and shielding the operator against sparks and chips which may be cast off from the cutting zone.
  • a console 3d is also carried by the arm and is provided with switching devices necessary for control of the apparatus. Since, apart from the hydraulic means for restricting the play of the moving parts, the control means is not part of the invention and is conventional,
  • the blade 4 is provided with V-belt pulleys which are connected by V-belts enclosed within a shield 3e with the driven pulleys of a motor 3f ment of the arm 3a, 3b about its pivot axis 2b in a plane parallel to the plane of the paper, there is provided a hydraulic arrangement 3m consisting of a hydraulic cylinder 3n pivotally connected at its lower end to the carriage 2 and receiving a piston 3p pivotally connected at its upper end 3q to the arm 3b.
