Definitions

  • the invention is directed to a riveting 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.
  • the stage belonging to the lower tools is spring-loaded against an upper stop and has a central recess as a receptacle for the hollow rivet cap, in which the stationary lower punch of the lower tool is arranged and the hollow rivet cap, which is loosely located in the recess, is supported on its end face.
  • 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 pressed down by the top tool.
  • a functional part such as. B. a snap part equipped with die-shaped closing surfaces
  • an associated complementary functional part such as 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 markings on the front were therefore not visible to the operator when riveting. Transferring the markings from the front to the back of the carrier web is tedious, time-consuming and cannot always be carried out precisely enough. Securing the position of the part positioned in the lower tools, namely the fastening part always provided there, is not always satisfactory.
  • the invention has for its object to develop a riveting 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 can be placed over the lower tools with its front side bearing the markings facing upwards, because the functional part is now positioned by the lower tool.
  • the operator can therefore set the exact position of the carrier web with respect to the riveting point when placing the carrier web on the front markings.
  • 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, however, is 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 pair of lower jaws 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 depending on the type of functional part to be attached and the type of fastening part used.
  • As a functional part In addition to male-shaped or die-shaped locking surfaces with push-button parts, buttons, hooks, eyelets can also be used.
  • the holding elements on the fastening parts, which can be used here, can be bent staples, compressible shafts or rollable hollow rivets.
  • push-button parts designed as so-called "spring parts” it is recommended, as proposed in claim 6, to form the straightening elements from a pin having a conical tip.
  • the contact points on the leg extensions will be made adjustable.
  • its locking surfaces release the spreading of the upper pliers and, through control surfaces, also cause the precise spreading movement of the pliers themselves, which then release the fastening part from their receiving profiles in the legs.
  • the fastening part is then already secured in position by its interaction with the functional part and possibly by guide surfaces of the straightening elements positioning the functional part in the lower punch. 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.
