Definitions

  • the control body which can be produced as a stamped part from a steel plate or in one piece with the hand lever as a forged part and only requires minor finishing on the surfaces of the slot, is also an additional guide element of the expanding mandrel and also secures it against rotation. It goes without saying that the thickness of the control body corresponds at least in places to the clear distance between the side cheeks of the expanding mandrel.
  • the ends of the arcuate slot form stops for limiting the pivoting angle of the pivotable hand lever, so that the arc angle of the slot is limited in a defined manner. This achieves two things: Firstly, one stop limits the approach of the hand levers to a minimum distance that prevents pinching, and secondly, the actuating force of the hand levers is defined at the end of the expansion process.
  • control body is designed as a plate-shaped component and is inserted into a parallel-walled slot in the movable hand lever. This enables, for example, a construction in which the tool body and the two hand levers are made of a light metal alloy, but the control body is made of steel.
  • the slot-shaped recess 10c has such a circumference with respect to the axis 7 that the base 10d of the recess 10c does not abut the tab 21 in any possible position of the hand lever 12.
  • the control body 109 has a slot 114 which extends from one side to the other and runs in an arc around the pivot axis 108 and is delimited on one side by the first control cam 113 and on the opposite side by a second control cam 115.
  • the clear width of the slot 114 corresponds at every point to the diameter of the roller 107 (plus a small amount of play), so that the roller 107 is enclosed in the slot 114 and positively guided in both directions of movement of the expanding mandrel, the control curve 113 the expanding process and the roller 107 engaging control curve 115 causes the forced retraction.
  • the retraction device 126 is formed by a part of the control body 109 which carries the control curve 115.
