Definitions

  • the molding die is arranged in a spring-loaded guide plate arranged above the die. Due to the spring load, the guide plate guarantees a clean pressing on the workpiece, even if it has slightly different thickness dimensions. With appropriate relief of the springs, the workpiece, in particular strip material, can be advanced.
  • the embodiment of the device essentially comprises a die 11 with an opening 12, a guide plate 14 supported by compression springs 13 and a die 16 guided displaceably in a guide opening 15 of the guide plate 14.
  • the guide plate 14 can be lifted off the die 11 is strip material 17 can be positioned between these two and moved forward.
  • the strip material 17, which is preferably made of sheet steel, is then rolled into the shape of the corresponding support element 1, 3 in a further operation.
  • the die 16 has at its lower end a chamfered stamping area 18, an embossing area 19 arranged directly above it and a calibration area 20 above it.
  • the punching area 18 has a cross section somewhat compressed on one side, which, however, is otherwise adapted to the shape of the upper diameter D M of the opening 12 of the die 11.
  • This invention is not only applicable for building supports, but basically for all metallic components that are to be connected to another component via a pin / hole connection.
