Definitions

  • the present invention relates to a portable rivetting machine of the type indicated in the preamble of Claim 1.
  • US-A-3.156.920 discloses a magazine construction for a portable rivetting machine in which the channel of the magazine is provided with one pair of longitudinal dividing walls which extend from its base wall such as to define a pair of symmetrically disposed interstices adapted to receive the legs of U-shaped staples of a predetermined width and a central interstice adapted to receive a series of rivets.
  • a rivetting machine provided with a magazine of the aforesaid known type shows a certain degree of versatility because it is able to receive both U-shaped staples of different height, that is with legs of different lengths, and rivets or nails of different lengths.
  • this known magazine is able to receive only staples of the same width.
  • the magazine according to US-A-3.156.920 is provided with a pusher which comprises three parallel blades, with each blade being housed in an interstice.
  • the blades are interconnected by a yoke which simply rests on the upper edges of the channel.
  • This arrangement is affected by tilting of the pusher.
  • an even slight inclination of the pusher has the effect of exerting on the last element of the series a thrust which is not parallel to the direction of movement, with the consequence of jamming of the staples or rivets in the slit at the discharge end of the magazine.
  • the object of the present invention is to provide a more versatile rivetting machine which not only is able to receive, selectively, series of rivets of different lengths and series of staples of different widths and of different lengths, but is also more reliable than the known rivetting machines in that it is not liable to jamming even in the case of very long rivets or staples.
  • a stapling machine is able to receive, in addition to rivets, also U-shaped staples of two different widths and of many different lengths.
  • the guide means which prevent the pusher from inclining ensure that the thrust is always exerted by the pusher in a direction parallel to that of movement of the staples or rivets, thus preventing possible jamming.
  • a rivetting machine comprises, in known manner, a body 10 with a base part 12, a part 14 acting as a handgrip and a head 16.
  • a head 16 In the head 16 is housed, in known manner, an electromagnet which can be selectively energised by means of a trigger 18 to cause a blade punch for discharging staples from the machine, to descend.
  • a sheet-metal channel 20 which accommodates a series of rivet elements. As will be seen below, these elements are urged towards the end of the channel 20 underlying the head 16 where the blade punch discharges them one by one through a slit defined by a pair of mating plates 22 and 24 of which more will be said below.
  • a slidable foot 26 is connected to the channel 20 for supporting the rivetting machine on the working surface P.
  • the channel 20 includes an outer sheet-metal element 28 of substantially U-shaped profile, with side walls 30 and a base wall 32. Within the outer element 28 there is located a further U-shaped, sheet-metal element 34 which has a base wall 36 applied to the wall 32, and two side walls 38.
  • the walls 38 and strips 40 define respective pairs of longitudinal dividing walls which extend up from the base wall of the channel and which define a pair of outermost interstices 50 (between the walls 30 and the walls 38), a pair of innermost interstices 52 (between the dividing walls 38 and 40), as well as a central space 54 (between the dividing walls 40).
  • the dividing walls 38 are higher than the dividing walls 40.
  • a pusher 56 is slidable in the channel 20 and comprises an outer sheet-metal element 58 in the form of an upturned U with a pair of sides 60 and an upper yoke 62.
  • An internal sheet-metal element 64 is located within the outer element 58 and has an upturned U profile with a pair of side walls 66 and an upper yoke 67.
  • a plate element 68 which has tabs 70 on its upper edge.
  • the tabs are inserted in respective slits 72 in the internal U-shaped element 64 and slits 74 in the outer U-shaped element 58, and are upset to secure the three elements 62, 64, 68 together in the configuration illustrated in Figure 5.
  • the walls 60,66 and 68 define respective blades each of which is housed in one of the interstices of the channel 20. As will be understood below, these blades serve to engage the rear end of the respective series of rivet elements and push them towards the discharge end of the channel 20.
  • a pair of lugs 76 Projecting from the upper yoke 62 of the outer U-shaped element 58 is a pair of lugs 76 through which a longitudinal guide rod 78 can slide.
  • a hook member 80 of shaped sheet-metal is fixed to the rear end of the rod 78 and can be hooked, in known manner, to the entry end of the channel 20.
  • a helical spring 82 is interposed between the pusher 56 and the hook member 80 for the purpose of resiliently urging a series of staples along the channel 20 by means of the blades of the pusher 56.
  • An appendage 84 in the form of a plaque bearing a reference mark 86 is mounted on the rod 78 between the lugs 76.
  • the plaque 84 projects through a slot between the channel 20 and the base part 12 of the body 10 and is movable along a scale 88 ( Figure 1) to indicate the position of the pusher 58 in the channel 20 and hence the quantity of rivet elements contained in the channel itself.
  • the side walls 30 of the channel have respective longitudinal ribs 90 which define corresponding internal grooves 92. In these grooves 92 are guided corresponding longitudinal ribs 94 of the pusher 56.
  • This coupling has the object of preventing the pusher 56 from inclining with respect to its direction of sliding, since inclination of the pusher could cause the rivet elements to jam, especially the last element to be discharged.
  • the foot 26 is constituted by a substantially U-shaped sheet-metal element. In the upper part of its side wall, it has respective stepped wings 96 which embrace the ribs 90. Tabs 97 are formed in the wings 96 by semi-punching and engage the upper parts of the ribs 90. In this manner, the foot 26 is mounted for sliding movement along the channel 20.
  • the foot 26 has a front projecting part 98 which, when the foot is in its fully advanced position, is disposed beneath the plates 22, 24 and closes off the discharge slit to provide a safety barrier in periods when the rivetting machine is not in use.
  • the foot 26 can be fixed in this advanced position by means of a side screw 99 ( Figure 5) which can be screwed into one of the side walls of the channel 20 through a corresponding hole in the foot 26, one of the ends of which, moreover, is arranged to be in front of the pusher 56 to prevent its advancement.
  • a first type of rivetting element is shown as E, and is constituted by a relatively wide, short staple.
  • the transverse or yoke part of the element E rests on the upper edges of the outermost pair of dividing walls 38 and the legs of the element E, are located in the outermost interstices 50 and slidingly embrace the dividing walls 38.
  • the pusher 20 ( Figure 5) pushes the series of elements E 1 by means of its outermost blades or sides 60.
  • FIG 7 a second type of rivet element E 2 which is relatively narrow and long.
  • the points or lower ends of the legs of the element E 2 rest on the base wall of the channel or rather on the base wall 36 of the innermost U-shaped element, and these legs are guided in the interstices 52 between the two pairs of dividing walls 38 and 40.
  • the pusher 56 ( Figure 5) pushes the series of elements E 2 by means of its pair of blades 66.
  • FIG 8 a further rivet element E 3 constituted by a rivet.
  • the point of the rivet rests on the base wall 36 and is guided within the central interstice 54 by means of the two dividing walls 40.
  • the pusher ( Figure 5) pushes the series of rivets by means of its middle blade 68.
  • the discharge slit at the end of the channel 20 through which the blade punch of the rivetting machine expels the rivet elements one by one is indicated by 100.
  • the slit 100 is defined between two mating plates, a front plate 22 and a rear plate 24.
  • the front plate 22 is formed with a wide groove 102 of a width such as to guide the rivet element E 1 as well as the blade punch (not shown).
  • the front plate 22 is also formed with a narrow central guide groove 104 for the rivet element or rivet E 3 .
  • the rear plate 24 is formed with a groove 106 of intermediate width which serves as a guide for the rivet element E 2 .
