Definitions

  • the present invention concerns a group of adaptor parts for a machine-punch suited to applying minute connecting pieces, especially eyelets, rivets and press-studs onto objects of textile, plastic, metal, leather, cardboard and similar materials, to be used in various and conventional manners.
  • the invention is suited for converting a riveting machine into an eyelet punching machine.
  • Machines for the application of these small pieces, generally made of metal, are divided into two main groups:
  • - chuck - defines the shaft that, having parts suited to operating on eyelets, rivets, press studs and similar, at its lower end, is provided with a down and upstroke movement.
  • a spindle that extends below a bushing set on the bottom of the chuck feeds one eyelet after the other from a convenient distributor; then, the spindle retracts into the bushing at the bottom of the chuck at the moment in which the eyelet is applied; the spindle must extend during the final part of the upstroke movement of the chuck; to this purpose, a device to extract the spindle from the eyelet comprising a cylinder sliding within the chuck and fixed to the body of the machine by means of a pin that transversally crosses the chuck along which a slot is set with length slightly more than the chuck's stroke (generally 50-60 mm). Perforating eyelet punches are called this way because in them the spindle also works in perforating the material onto which the eyelet must be applied.
  • each rivet is fed from an appropriate box by means of a pincer-punch unit that accompanies it until its application.
  • the purpose of the present invention is to greatly simplify the conversion of one of these machine-punches, especially of a riveting press into an eyelet punch or of an eyelet punch into a riveting press, in order that the conversion may be conducted by not specially expert personnel.
  • the chuck of a riveting press is the more simple of the chucks of the two different types of machine in as much as the job of feeding and then applying the rivet is performed by a pincer bearing a punch screwed onto the bottom end of the chuck; it is therefore understood that the device invented is especially suited to being applied on a riveting machine.
  • the group invented comprises a main part that can be screwed into the threaded cavity existing in the bottom end of the chuck of said machine-punch and bears means to feed and apply an eyelet and means for extracting the spindle from the eyelet applied, such means comprising: a tool-holder with its upper end that can be screwed into said threaded cavity in the chuck, two opposite longitudinal slots made in its lateral walls and a chamber in which an extractor cylinder slides and transversally crossed by a pin each end of which slides along said slots and held in a sleeve sliding along the tool-holder, the purpose of the sleeve being that of resting against a fixed or adjustable part of the machine-punch at the end of upstroke of the chuck, in order to extract the spindle from the eyelet.
  • a part of the group invented, conventionally defined as secondary, that operates to perforate the material to which the eyelet is applied, will be specified below with reference to figures 3 and 4.
  • the invention may also be realized for use on a pre-existing machine, given that the geometries of the parts to be connected are compatible.
  • Figure 1 shows part of a riveting press onto which the main part of the device invented to convert the riveting press into a simple eyelet punch, is fitted, that is an eyelet punch that does not previously perforate the material onto which the eyelet must be applied;
  • a chuck 1 is conventionally fitted to a fixed part 2 of the machine in order to perform the necessary upstroke and downstroke movements under control of a leverage 3 run by a motor means that is not shown;
  • a sleeve 4 is fixed that bears a roller 5 laterally that acts on a rectilinear cam 6 (roller 5 and cam 6 are only visible in Fig.
  • the chuck 1 has a threaded cavity 8 in its bottom end into which the invented device is screwed, for the application of eyelets, instead of a conventional pincer and stud for the application of rivets;
  • the device invented comprises: a tool-holder 9 with threaded top 10 screwed in said cavity 8 and with lower bore 11 bearing bushing 12 with the purpose of acting as a guide for a spindle 13 fixed into the tool-holder by means of two opposite transversal screws 14 that work by friction against the walls of the spindle; two longitudinal slots 15 diametrically opposite in the lateral walls of the tool-holder; an extractor cylinder 16 sliding within a chamber 9A of the tool-holder and connected, by means of a transversal pin 17 having its ends sliding within the two slots, to a sleeve 18 sliding along the tool-holder.
  • the figure also shows: a conventional counterpoint 19 under the device, a piece of material M between the tip of the spindle 13 and the counterpoint 19 and a body 2A of the machine that is moved parallel to the chuck and fixed into the appropriate position by means of screw V to check the upstroke of the same chuck.
  • Fig. 2 shows the conventional eyelet distributor 7 fitted on the machine next to the chuck 1 and from which the spindle 13 conventionally takes an eyelet O at each cycle; the figure also shows the roller 5 rotating on sleeve 4 solid with the chuck, cam 6 fixed to distributor 7, tool-holder 9 and spindle 13.
  • the unit described above works as follows: during the descending stage of the chuck, the point of spindle 13 hooks an eyelet O and firmly grips it thanks to the action of friction screws 14; then, roller 5 acts on cam 6 to laterally push away distributor 7 in order to avoid that the latter be hit by the descending tool-holder 9; further, the point of spindle 13 presses against material M and spindle 13 begins to slide along friction screws 14 thus retracting into bushing 12 that begins to press upon the head of the eyelet causing its punching against counterpoint 19; after this, the chuck ascends with spindle 13 completely retracted into bushing 12, in the last part of the upstroke the sleeve 18 is stopped by fixed part 2 of the machine so that the spindle is extracted ready for punching the next eyelet.
  • Figure 3 shows part of a conventional riveting press onto which the main part and the secondary part of the group invented have been applied to convert the riveting press into a perforating eyelet punch;
  • a chuck 1 with a cavity, conventionally set to receive the parts relative to the perforating function, is fitted to a fixed part 2 of the machine and externally, as for the chuck described in Fig. 1, is fitted a sleeve 4 laterally bearing a rotating roller 5 that acts upon cam 6 to push away distributor 7; the sleeve 4 and body 2A that can be moved parallel to the chuck perform the functions already described with reference to Fig.
