Definitions

  • This machine comprises a device for setting the position provided for the article to be punched, which comprises a setting templet and a control member, one of these members being fixed and the other associated with the movable support for the article to be punched, and the fixed member of this device is mounted on the frame of the machine in such a manner as to be able to be displaced parallel to the plane of alignment of the punches.
  • This member is coupled to the movable striking hammer, or to the means for controlling the displacement of the same, along the plane of alignment of the punches, in such a manner that the displacement of this hammer in this direction causes an identical displacement of the fixed reference member of the setting device.
  • the object of the present invention is to provide a punching machine which belongs to the second category but avoids all these disadvantages, by ensuring an automatic correction of the position of the work table depending on the selection of the punch, whatever the distance between the axes of the punches and the position of the selected punch may be.
  • the fixed reference member of this device is mounted on the frame of this machine in such a manner as to be able to be displaced parallel to the alignment plane of the punches, and this member is coupled to the movable striking hammer, or to the means for controlling the displacement of the latter along the plane of alignment of the punches.
  • the arrangement is such that the displacement of this hammer in this direction, to bring a different punch into service, causes an identical displacement of the fixed reference member of the setting device. Under these conditions, the setting device is automatically subjected to the required correction to make allowance for the position of the punch freshly brought into service.
  • the templet of the setting device When the templet of the setting device is associated with the movable support for the article to be punched and the fixed member of this device consists of a stylus or other reference member, the latter is mounted in such a manner as to be displaced parallel to the plane of alignment of the various punches on each change of punch and this stylus is coupled to the movable striking hammer, for example by means of a simple connecting rod.
  • this templet is mounted in such a manner as to be able to be displaced parallel to the axis of aligment of the punches. It may then be coupled to the control means adapted to ensure the displacement of the striking hammer opposite the punches in such a manner that the position of this. templet is modified on each change of punch.
  • FIG. .1 is a perspective view of a first form of embodiment of a punching machine according to the invention.
  • FIG. 2 is a plan view from above of the work table of this embodiment:
  • FIG. 3 is a diagrammatic view in perspective of the device for controlling the punches
  • FIG. 4 is a diagrammatic plan view from above of the work table of another machine according to the invention, corresponding to a second form of embodiment
  • FIG. 5 is a partial view in side elevation of this machine
  • FIG. 6 is a view thereof in partial section on the line VI-VI of FIG. 4.
  • the machine illustrated in FIGS. 1 to 3 comprises a movable table or platen 1 adapted to receive the article 2a to be punched and mounted above the platen 4 of a lower frame 5.
  • This table 1 is adapted to be displaced in two perpendicular coordinates X-Y. For this purpose, it is mounted for sliding in the direction of the axis X on a horizontal rail 6 carried by the front edge of a platen 7 itself mounted for displacement above the platen along the axis Y.
  • the platen 7, which may be in one or more parts, is itself mounted for displacement on two parallel horizontal rails 8 fixed to the frame (see FIG. 2).
  • the table 1 is equipped with an operating handle 11. Moreover it comprises a clamping member 12a adapted to ensure the fixing in position of the article to be punched 2a. In addition, a block 13a enables the initial position which should be given to this article to be determined.
  • the upper head of this hammer is mounted for sliding in a dovetail groove 21 extending parallel to the plane AB and formed in a block 22 adapted to be displaced vertically to control the bringing into action of the selected punch.
  • the present machine comprises a device for setting the position of the article to be punched, which device is adapted to be subjected automatically to a correction when the punch brought into service is changed, in such a manner as to make allowance for the position of the respective punch.
  • This templet is adapted to be fixed to the movable table 1 serving as a support for the article to be punched so as to be associated therewith.
  • this table is provided with fixing pincers 12h as well as with a setting block 1312 enabling the templet 2b to be fixed in a predetermined position on the table.
  • the placing in position of the article to be punched, before each punching, can thus be effected by bringing the work table 1 into such a position that the corresponding hole already existing in the templet 217 is exactly opposite the stylus 16.
  • This operation therefore enables the article 2a to be punched precisely at the required point.
  • the stylus l6. constituting the fixed reference member of the setting device, can be displaced parallel to the plane AB of alignment of the punches. Moreover, it is coupled to the striking hammer in such a manner as to accompany this in its displacements parallel to the plane AB of the punches. As illustrated. this coupling may be effected by a simple connecting rod 23.
  • the striking hammer 20 may be actuated by any suitable means, for example by means of a sliding wedge 24 adapted to be displaced in a plane perpendicular to the axis of the displacements of this hammer.
  • This wedge is mounted for sliding against an inclined plane 25 formed on the top of the block 22 carrying the striking hammer.
  • This table is fixed to the body 33 of two jacks provided close to each end and the fixed rods 34 of which extend parallel to the axis Y.
  • these jacks enable the table In to be displaced parallel to this axis.
  • the setting device provided in the present machine consists as before of a templet 2b and a reference stylus 16a.
  • the arrangement provided is the reverse of that existing in the previous form of embodiment.
  • the stylus 16a is not fixed but, on the contrary. associated with the support for the article to be punched 2a.
  • the support 35 for this stylus is actually rigidly connected to the carriage 31 serving as a support for this article.
  • the setting templet 21) on the other hand is fixed instead of being associated with the support for the article to be punched.
  • a punching machine comprising a frame; a platen above said frame movable in two directions which are normal to each other; means connected to said frame and said platen for guiding the latter movable in said directions; means on said platen for holding a workpiece to be punched and a templet in fixed position and laterally spaced from each other for movement with said platen in said directions; a series of punches ofdifferent cross-sections having parallel axes located spaced from each other in a common plane substantially normal to said platen; means fixed to said frame for guiding each of said punches movable from a rest to an operating position for punching a hole in a workpiece carried by said platen; striking means movable in said common plane for alignment with a respective one of said punches and cooperating with a respective punch for moving the same from said rest to said working position; a stylus cooperating with said templet and mounted for movement in said common plane; and means for connecting said stylus with said striking means for adjusting the position of the latter in said plane in accord
