Definitions

  • the invention is directed to a rivet press of the type mentioned in the preamble of claim 1.
  • the upper tools lead the functional part, namely a push button part, while the lower tools for positioning the associated fastening part, namely a cap carrying a rivet can be used.
  • which belongs to the lower tools stage is spring-loaded against an upper stop and as a housing for the hollow rivet cap has a central recess in which the fixed lower punch of the lower tool is disposed and hollow rivet cap loosely located on its front face in the 'recess is supported.
  • the height of the platform is changed passively by pressing the top pliers by pressing the platform downwards against its spring load and thereby moving the hollow rivet cap resting on the end face of the lower die in its recess against the carrier web that is pressed down by the top tool.
  • a functional part e.g. a push-button part equipped with a die-shaped closing surface
  • an associated complementary functional part e.g. such a functional part
  • the markings for placing such functional parts are arranged on the front of the carrier web.
  • the functional part since, as already mentioned, the functional part always had to be fed from above through the top tongs of the carrier web, it was necessary to always place the carrier web on the stage of the lower tools with the rear facing upwards.
  • the invention has for its object to develop a rivet press of the type mentioned in the preamble of claim 1, which allows a reliable, accurate and safe attachment of the functional parts with the fastening parts on the carrier web using the markings located on the front of the carrier web. This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following meaning.
  • the carrier web with its front bearing the markings facing upwards can be placed over the lower tools because the functional part is now positioned by the lower tool.
  • the operator can therefore use the front markings to place the carrier web on the exact position of the carrier web the riveting agency.
  • the functional part is in turn precisely positioned by the lower jaws, which are mounted on the stage and can be spread, and the functional part is in the mounting profile.
  • the stage equipped with the lower jaws has its own lifting drive, which is, however, derived from the lifting drive of the upper tool, in particular the upper punch according to subclaims 2 and 3, but no separate drive is required for the spreading movement of the lower jaws, because the control surfaces between the Lower jaw pair and the stationary lower punch automatically cause the jaw spread when the lower jaw pair has moved down sufficiently.
  • the functional part comes out of the mounting profile between the lower jaws, but the precise positional securing of the functional part is taken over and guaranteed during the further downward movement of the lower jaws and during the actual riveting by straightening elements which are arranged on the end face of the lower punch.
  • These straightening elements can, as proposed in claim 5, at the same time have guide surfaces for the deformable holding elements of the fastening part supplied by the upper tool, so that the holding elements precisely enter the functional part and are properly deformed there. This enables a flawless, secure and precisely positioned attachment of the functional part to the carrier web.
  • connecting rods which connect a lever belonging to the lifting rod of the upper punch with a pivotable arm which at its free end stage equipped with the buttocks.
  • the connecting rod according to claim 4, will be designed as a telescopic rod with axial suspension.
  • the mentioned straightening elements on the end face of the lower punch are designed as a function of the type of functional part to be attached and the type of fastening part used.
  • push-button parts buttons, hooks, eyelets can also be used as the functional part.
  • the holding elements on the fastening parts which are used here, can be bendable staples, compressible shafts or roll-in hollow rivets.
  • Such restricted areas can simply consist of bundle-like thickenings according to claim 9.
  • the contact points on the leg extensions will be made adjustable.
  • its blocking surfaces release the spreading of the upper pliers and furthermore cause the precise spreading movement of the pliers themselves through control surfaces, which then release the fastening part from their receiving profiles in the legs.
  • the fastening part is then already secured in position in the lower stamp by its interaction with the functional part and possibly by guide surfaces of the straightening elements positioning the functional part. This ensures perfect riveting at all times.
  • FIG. 1 shows the components of the riveting press according to the invention which are relevant for riveting, from which their mutual position and their drive can be seen, from which the lifting movements of the tools explained in more detail in the following FIGS. 2 to 7 result.
  • the upper tools include a pair of pliers lo 12, which will be referred to as “upper pliers” for short, and a plunger 11 which is guided between the pliers legs 12 and can be referred to as “upper plunger” for clarity.
  • the upper punch 11 has a lifting linkage, consisting of a punch holder 13, an associated tappet 14 and a double-armed lever 16, which is received in a pivot bearing 15 of the riveting press and one arm of which is connected to a link 17 and a further articulation point on the tappet 14 is connected, while the other lever arm is driven by an eccentric shaft 19 via a hinged connecting rod 18.
  • the rotation of the eccentric shaft 19 indicated by the rotary arrow 31 in FIG. 1 causes a lifting movement 30 of the upper punch 11 with a specific lifting amplitude 97 according to FIG. 2.
  • the pliers legs 12 of the upper pliers 10o are attached to a bearing plate 33 by way of bearing pins 32 and carry pins 34 which pass through edge recesses 35 of the bearing plate and are spring-loaded against one another by a tension spring 36.
  • the bearing plate 33 is connected via an extension 38 to a rod 39 which belongs to its own lifting rod.
  • the lifting linkage is designed in the manner apparent from DE-OS 25 56 516, the description of which is made the subject of the present invention.
  • the linkage comprises a composite of two angular planes 4 0, 41 toggle.
  • One angle lever 4o is mounted on a pivot bearing 42 in the rivet press and articulated on the rod 39 at the free end of its one, essentially horizontally extending angle arm, while the other angle lever 41 in Vertex area is pivotally attached via a hinge 43 to a bracket 44 extending the horizontal arm of the first-mentioned angle lever 40.
  • the angle lever 41 is provided with a roller 45 which, via a tension spring 46 or the like acting on the angle lever 41, rests against a cam disk 47 which is rotated together with the eccentric shaft 19.
  • the two downwardly extending legs 48, 49 of the two angle levers 4 0, 41 normally lie against each other and thereby stiffen its hinge -43.
  • the lower tools initially comprise a stationary punch 21 which is fixedly held in the frame 22 of the riveting press and which will hereinafter be referred to as "lower punch” for short.
  • a swivel arm 23 is received in a fixed bearing 24 of the machine frame and carries at its free end via an intermediate piece 25 a plate-shaped stage 26, which serves as a bearing plate for a pair of jaws 27, the hereinafter referred to as “lower jaws 27" and form the lower tool 2o of the riveting press.
  • the lower jaws 27 are pivotably guided on the bearing plate 26 by means of bearing pins 28 and carry pins 29 which pass through elongated holes 53 in the bearing plate 26.
  • the pins 29 are at their pin ends projecting below the bearing plate 26 with a tension spring 54 od. Like. Provided, which has the result that the free ends of the lower jaw 27 with their special, see Fig. 8 receiving profile 55 endeavor to get into a Z fold-up position.
  • the end position of the lower jaw 27 in Z uklapplage may be generated in the bearing plate 26 53 by a stop action between their pins 29 and of the opposing swept ends of the slots.
  • the bearing plate 26 is also provided towards the swivel arm 23 with a guide slot 56 to be described in more detail in its function.
  • the lower tool 2o with the pair of jaws carries out its own lifting movement, indicated by the arrow 57 in FIG. 1, which, however, is derived from the lifting movement 3o of the upper punch 11 via a connecting rod 6o.
  • the one rod end 61 is, as shown in FIG. 1, connected to the swivel arm 23 via a joint 58 and has a telescope 62 which is under internal spring loading.
  • the other rod end 63 is via adjusting rings 64 adjustable on the threads of the rod and a counter spring 65 through which Bore of a boom 59 passed through, the boom 59 being articulated on the lever 16 belonging to the lifting rod of the upper punch 11.
  • the lifting movement 57 is brought about in the pair of jaws 2o of the lower tool via the connecting rod 6o.
  • the stroke movement 57 of the pair of jaws 2o takes place with a different stroke amplitude 95 than the stroke movement 3o of the upper punch 11, but is in phase therewith.
  • the guide channel 66 for the loading slide 67 of a feed device 68 for functional parts 7o is arranged above the swivel arm 23 and, in the present case, consists of push-button parts Matrix-shaped closing surfaces 71 exist, as can best be seen from the axial section in FIG. 2.
  • the push-button part 7o consists of a shaped sheet metal body which, according to FIG. 2, consists of a pot 73 provided with a bottom opening 72, on which a circumferential flange 74 is formed, which serves to receive spring elements 75.
  • the spring elements 75 protrude through lateral openings into the interior of the pot 73 and produce in the interior of the pot the matrix-shaped closing surfaces 71 which, when the push button is used as intended, interact with complementary male-shaped closing surfaces of the associated other push button part, which are not shown in detail.
  • the upper tools 10, 11 are also provided with a feed device 83, which is indicated here and to which a guide rail 84 divided by a longitudinal slot belongs.
  • the fastening parts 9o As a deformable holding element, has a hollow rivet 92 provided with a flange 91, the flange 91 including a cap which contributes to the formation of caps is provided.
  • the flange 91 and the spherical cap 93 form a head 94 with which the rivet 90 is first guided in the guide rail 8 4 to a gate (not shown in more detail) at the lower mouth of the guide rail 84.
  • a racket 85 is pivotally guided between the division slots in the guide rail 84 and is set in motion by a pivoting drive 86.
  • the rivets are arranged in a row in the guide rail 84 from a storage container.
  • the striker 85 grips the foremost rivet during its pivoting movement and presses it into the receiving profile 37 already mentioned there, with the pliers legs 12 springing open.
  • the receiving profile 37 detects the inserted rivet 90 on its head 94 and aligns it radially and axially on all sides with the upper punch 11.
  • the upper tongs 10 are provided with a fastening part 9 0 , namely a rivet, and the lower jaws 27 are equipped with a functional part 7 0 , namely a push-button part.
  • both the upper tools 10, 11 and the lower tool 2o in FIG. 2 are each in their top dead center position, there is a large distance 87 between them which allows the convenient arrangement of a carrier web 100, for example a piece of clothing, on the lower tools 2 0 , 21 allowed. Namely, the front side lol of the carrier web is placed upwards for the operator to see, while the rear side lo2 is facing the tools 2 0 , 21.
  • a marking usually provided on the front of the web 10 can be positioned by the operator in alignment with the stroke of the upper tools 10, 11.
  • the axes of the upper tools 10, 11 and lower tools 2 0 , 21 are aligned axially below one another, but, as already mentioned, the tools perform lifting movements 30, 52, 57 with different lifting amplitudes 95, 96, 97, as from a comparison can be seen between FIGS. 2 and 6, where the end face 99 of the fixed lower punch 21 is indicated as a dash-dotted reference plane 98.
  • the pair of jaws 2o has moved downward from the lower tool relative to the lower punch 21 to such an extent that a central straightening element lo8 projecting over its end face 99 has entered the receptacle of the push-button part 7o.
  • the straightening element here consists of a central pin lo8 with a conical tip 1 0 9.
  • the conical tip 1 0 9 cooperates centering with the bottom opening 72 mentioned in the pot 73 of the push button part 7o.
  • the push-button part 7o is moved by the spring load 82 in the mentioned receiving profile 55 the lower jaw 27 held unchanged.
  • the lower punch 21 has reached a cylindrical entry opening 10lo, which can best be seen in FIG. 8, due to the downward movement 57 of the lower tool 2o, which also causes the lower jaws 27 to be centered with respect to the lower punch 21.
  • the upper punch 11 performs a substantial part of its stroke amplitude 97 and thereby hits the head 94 of the rivet 9 0 when the upper pliers lo have their bottom dead center of their stroke amplitude 96, which can be seen in FIG. 6 almost reached.
  • the mentioned thickening 89 has moved below the contact points lo5 of the two leg extensions lo3, thereby making the pliers legs 12 expandable again.
  • the punch holder 13 also has control surfaces 111, which interact with corresponding counter surfaces 112 of the two pliers legs 12 and spread them against the action of their spring 36 in the direction of the arrows 12o.
  • the receiving profile 37 of the pliers legs 12 thereby releases the head 94 of the rivet 90 and the upper punch 11 can, as shown in FIG. 9, push the hollow rivet 92 through the carrier web.
  • the hollow rivet 92 meets the conical tip lo9 of the central pin lo8 from the lower punch 21. Its conicity serves as a guide surface lo9 for the hollow rivet.
  • the lower jaws 27 have a funnel-shaped exit opening 113 above their receiving profile 55 for the push-button part 7o, which is narrower than the width 114 of the lower punch 21.
  • the funnel-shaped exit opening thus forms lateral control surfaces 113 which act against the peripheral surface 115 shown in FIG. 8 of the lower punch 21 and thereby also perform a spreading movement of the two lower jaws 27 indicated by the arrows 116 in FIG. 6. As a result, the pushbutton part 7o held in the receiving profile 55 of the lower jaws 27 is released.
  • the upper punch 11 also reaches its bottom dead center and, in interaction with the lower punch 21, carries out the desired riveting work; the end of the hollow rivet 92 is deformed at the conical pin tip 1o9 and engages around the bottom of the pot 73, as a result of which the rivet fastening 7o can be seen in FIG. 7 on the carrier web 10o by the rivet 9o.
  • the carrier web 7o equipped with the push-button part 7o is thus exposed, as shown in FIG. 7, between the tools 10, 21 and can be easily removed from the riveting press by the operator. Due to the faster downward movement of the upper punch 11, the mentioned lateral control surfaces 111 on the punch holder 13 finally reached above the counter surfaces 112 between the two pliers legs 12, so that these could move back into their pull-down position under the action of their spring 36, which were secured by stops is, which come about, for example, by the pins 34 located on them and the edge recesses 35 of their bearing plate 33.
  • the tools lo, 11, 2o then move back to their starting position shown in FIG. 2 at the top dead center of their stroke amplitude 95, 96, 97, where they again with a new push button part 7o and a new rivet 9o of their feed devices in the manner already described 68, 83 can be loaded.
  • the feed paths of these two devices 68, 83 are offset at right angles to one another, since the pivoting movement of the striker 85 takes place from the side, while the loading movement of the slide 67 in the lower tool 2o is at right angles from the back to the front. Accordingly, the pivoting planes of the upper tongs 10 are oriented at right angles to one another with respect to the pair of lower jaws 20, as can best be seen from FIG. 12.
  • the forceps legs 12 and the lower jaws 27 are shown in FIGS. 2 to 7 in the same plane with their spreading directions 12o, 116, which are best seen in FIG. 6.
  • an inlet funnel 121 which can be seen in FIG. 3, is provided in front of the receiving profile 37 between the pliers legs 12 and has guide surfaces for the correct feeding of the fastening part 9o.
