Definitions

  • ABSTRACT Improvements in machines for punching characterized by an orientable tool-holding gooseneck, the pivoting axis of which coincides with that of the tool, comprising means for the angular immobilization and frictionless support on a partly circular area, of the rotation of the said gooseneck permitting, on the one hand, increasing the punching capacity without altering the initial precision, and, on the other hand, obtaining, with the aid of a single tool, various cutouts in any desired positioning angle.
  • the object of the present invention which remedies these drawbacks, is a machine for punching by copying, remarkable in that the gooseneck constituting the tool holder can be oriented around a pivot whose axis coincides with that of the too], this rotation of the tool holder, which is at least equal to 180, makes it possible on the one hand to increase the punching capacity, while maintaining precision, and on the other hand, to obtain, with the aid of a single tool, punchings in any desired angle of positioning.
  • the pivot of the gooseneck of the tool-holder is borne by a table, that is at least semicircular, which has on its circumference, close to the perimeter, a plurality of holes for angular adjustment of the said gooseneck, which has, for this purpose, a corresponding set screw that can cooperate with one of the said holes, as well as means for displacing it without friction, on the surface of the supporting table which is adjacent to the usual table bearing the device for attachment and adjustment of the metal plate to be punched, which can be placed under the dependency of a manual or electronic control according to the type of machine used.
  • FIG. 1 shows in perspective, a punching machine with orientable gooseneck according to the invention.
  • FIGS. 2 to 4 are diagrammatic overhead view of the punch, showing certain possiblities of punching with the aid of a single tool.
  • 1 is the usual table of a punching machine with its device for clamping and adjusting the plate P to be punched, which can be displaced in two perpendicular directions according to arrows F and F (FIG. 2), either by hand or automatically by means of a programmed electronic control system, not shown, in order to bring said plate between the tool holder 2 and the matrix 3 'in the space determined by the usual gooseneck carrying these elements.
  • the gooseneck 4 is moveable in rotation on a pivot 5, the axis of which coincides with that of tool 6, with said pivot being borne by the center of a table 7 having the form of a segment of a circle equal to 180 or more, adjoining the usual table 1, and on which said gooseneck can be immobilized angularly.
  • the table 7 has, circumferentially, near its perimeter, a plurality of equidistant holes 8 corresponding to the usual divisions of the circumference, and with one of which a finger 9 can cooperate for the angular positioning of the gooseneck 4 borne by the sole 10 of the latter on the side opposite its pivot 5'.
  • rollers 11, borne laterally by sole l0 insure its displacement without friction on the surface of said table.
  • a punching machine with orientable gooseneck thus constituted, permits, for example, the making a series of aligned holes in plate P and then, by rotating said gooseneck 180, making a series of holes strictly similar and parallel to the preceding holes, by the manual or automatic displacement according to arrow F,, of the device for adjustable displacement of the latter, FIG. 4.
  • tool 6, of oblong shape makes it possible, after a first punching and after rotating the gooseneck to obtain cruciform perforations, or, by a rotation of and cutouts juxtaposed by displacement of the plate holder, rectangular or square perforations.
  • These various perforations can, according to the relative displacements of the moving parts of the machine, have an oblique arrangement relative to the sides of the plate, or can be distributed, for example, in line, staggered, stepped or circumferentially.
  • the present invention is not, of course, limited to the method of embodiment described and represented, but extends to all variants of pivoting, guidance and positioning of the tool-holding gooseneck.
  • a punching machine in combination, an oblong punching tool and a matrix, said tool and said matrix having a common axis, a gooseneck supporting said punching tool and said matrix, a table on which said gooseneck is supported, means for pivoting and immobilizing said gooseneck relative to said table, the axis of pivoting of said gooseneck coinciding with said common axis of said tool and said matrix.
  • a punching machine including in combination a punching tool, a gooseneck support said punching tool, means pivotally supporting said gooseneck and capable of retaining said gooseneck along the axis of said tool, means supporting the piece to be machined, and means for displacing said supporting means along two directions perpendicular to one another and situated in a plane perpendicular to the axis of rotation of said gooseneck.
  • a punching machine including in combination, a tool holding gooseneck, a table constituted by a segment of a circle at least equal to 180, means supporting the piece to be machined, and means for displacing said support of said piece in two directions perpendicular to each other and situated in a plane perpendicular to the axis of rotation of said gooseneck.
