Definitions

  • the object of this invention is an automatic device for the application and punch-fastening of rivets to supporting members which are to be joined.
  • rivets capable of being inserted through the thickness of substantially slablike members and of being deformed at one of their ends to ensure their irreversible fixing to the said slablike member.
  • rivets of hollow type which have on their inner surface a female thread capable of engaging a corresponding thread of a screw, bolt or the like the head of which is counterbored, for example on a tubular component with which the slablike member is to be made integral.
  • an automatic device for the application of rivets to substantially flat components comprising a fixed base with which is made integral a support in which are provided housings to accommodate means for the temporary holding of the rivets and means for supporting a punch, such means being designed to perform reciprocating and synchronized movements inside the relevant housings, under the controlling action of means for pushing and for joining, there being furthermore provided means for the automatic feeding of the rivets and means for pushing the latter, capable of inserting the rivet into such flat member and of countering the pushing action of the punch applied against the lower part of the rivet protruding from the flat member to bring about its deformation and compression on the flat slab in order to achieve the definitive fastening thereof.
  • such housings are of substantially semicircular shape to accommodate such means for the temporary holding of the rivets and substantially parallelepipedal to accommodate such means for supporting the punch, and that the means for the temporary holding of the rivet are preferably comprised of two substantially semicircular arms, the upper free end of which is shaped as a semicylindrical cavity with a blind end, on the lower end of such arms there being provided a roller designed to come into contact with such means of return.
  • such means for supporting the punch are preferably comprised of a slider, on the lower end of which are provided two opposite inclined planes on which run the rollers of such means of return; furthermore such means of return of movement are substantially comprised of two levers integral with one another, the free ends of which are respectively in contact with the pin of the arms and with the inclined plane of the slider by means of such rollers, the reciprocating longitudinal movement of the slider thus bringing about the corresponding synchronized reciprocating movement of the arms.
  • such means for pushing the rivets and for countering the thrust of the punch are substantially comprised of a counterpunch, operated in turn by hydraulic means in the opposite direction to that of the punch, while such means of actuation of the device are preferably comprised of a hydraulic cylinder made integral lengthwise with the fixed base and the rod of which is linked to the lower end of the slider.
  • the device according to the invention essentially consists of a fixed base 1 with the top of which is made integral a support 2 on which are provided two recessed housings 2a of substantially semicircular shape, and a cavity 2b located lengthwise which crosses vertically the entire support 2, interrupted in the vicinity of its upper end by a transverse baffle 2c which in turn is crossed axially by a hole 2d.
  • slider 4 At the upper end of slider 4 is furthermore made integral a punch 11, which performs corresponding movements of slider 4 guided inside longitudinal hole 2d of transverse baffle 2c.
  • Slider 4 also has on its lower part two opposite inclined planes 4a on which can run two rollers 5a respectively pivoted to one end of lever 5, the opposite end of which is pivoted to a pin 5b secured to support 2, to which is also pivoted a second lever 6, the free end of which is in contact with a roller 7a perpendicularly integral with the lower end of each one of a pair of arms 7, such levers 5 and 6 forming overall a rocker swivelling around such pin 5b.
  • Such arms 7 are of semicircular shape matching that of housings 2a within which they are located and within which they may slide as will be explained more clearly later.
  • the other free end of such arms 7 has instead a tip 7b made longitudinally hollow, of substantially semicylindrical shape which, when placed in contact with the other fork of second arm 7, forms an axial cylindrical housing capable of accommodating the lower part of a rivet 8.
  • rivet 8 which is fed automatically from a reservoir by means of a hydraulic or electronic device is placed in position by a punch 9 which forces it through the wooden or like slab 10 at the preset point of insertion until at least teeth 8a underlying the head of the rivet penetrate the wood to prevent rotation of the said rivet.
  • the operation of the device is as follows: when rivet 8 is inserted, in the manner described above, by punch 9 into slab 10 to which it is to be applied, the lower end of the rivet projects beyond the slab by an amount such as to enable it to be inserted into the cylindrical guide housing consisting of the two semicylindrical cavities 7b of arms 7 which, at this stage of the sequence, are closed in the upper position, whilst rod 3a of cylinder 3 is retracted, slider 4 and therefore punch 11 integral therewith are lowered, and levers 6 are rotated outward (fig. 1,3b).
  • a limit switch signal releases a valve, which is self-evident and therefore not illustrated, to actuate rod 3a of cylinder 3 in its upward outgoing direction, whilst slider 4 and punch 11 move toward rivet 8 until head 11a of the punch has penetrated the cavity at the lower end of the said rivet.
  • rollers 5a begin to run on inclined planes 4a of slider 4 causing the rotation of levers 5 and 6, the free end of which pushes on pin 7a causing arms 7 to rotate and open, thus enabling punch 11 to continue its upward stroke and at the same time release the lower end of rivet 8, which under the pushing action of punch 11, which is continuing its stroke, opens out and penetrates the lower surface of wooden or like slab 10, thus achieving the definitive fastening of the said rivet.
