Consequently, the angle of rotation between the guide body 44 and the drive cam plate 43 changes, which results in that the portion of the cam surface 49 acting at a maximum rotation of the drive cam plate 43 relative to the cam stop surfaces 48 of the notching elements 46 is limited.
  • the minimum receiving cross-section for receiving the connecting element to be pressed can be adjusted, that is, it can be done an adjustment of the Crimpginses to the size of the connecting element to be pressed. This kind of Setting the Crimpginses is of course also possible with manually operated pliers to which also such a screw can be attached.
  • FIG. 9 shows a crimping machine 52 with a crimping insert 23 according to the invention, on which the positioning device Ol is mounted.
  • the force generated by the crimping machine 52 is passed to the receiving adapter 27 via an actuator 53.
  • the positioning device oil can also be exchanged with the crimp insert 23 installed.

Abstract

L'invention concerne un dispositif de positionnement pour outils de sertissage. Des dispositifs de positionnement de ce type servent à placer un élément à comprimer par rapport aux éléments de compression d'un outil de sertissage, ces éléments comprenant des éléments de rainurage, des matrices de sertissage ou des éléments similaires. Le dispositif de positionnement de l'invention (01) comporte une tête support (03), rotative relativement à l'outil de sertissage (02.23), sur la circonférence de laquelle sont disposés plusieurs éléments de positionnement (11,12) qui sont chacun axialement mobiles entre une position de départ et une position de travail dans le sens de l'outil de sertissage (02.23). L'invention porte également sur un outil de sertissage, par exemple, une pince à sertir ou un insert de sertissage, pour une machine à sertir.
