Definitions

  • the present invention relates to a stop or crimping press for connecting contact parts to a conductor, in which an electric motor drives an eccentric shaft with an eccentric pin via a reduction gear, said pin running in a guide which moves the plunger up and down with the crimping tool.
  • the present invention therefore has as its object to improve a stop or crimping press of the type mentioned in such a way that the stroke of the ram changes in relation to the path of the circular movement of the eccentric pin during the downward movement to bottom dead center in such a way that for the approximately last one 10% of the stroke is available about a quarter turn of the eccentric shaft.
  • a synchronous electric motor 2 is mounted on a machine frame. This acts via a reduction gear 3 on an eccentric shaft 10 mounted in the machine frame.
  • the eccentric shaft carries the eccentric with an eccentric pin.
  • the eccentric pin lies in a guide which is part of a plunger which can be moved vertically up and down.
  • the plunger carries an interchangeable tool with which metal contacts, such as through connectors, end connectors, cable lugs and flag connectors, are pressed onto cables, in particular also stranded cables.
  • the electronic control is housed in the hinged box 4.
  • the eccentric shaft 10 is shown in detail in FIG. This is provided at the end with a flange 11 in which an eccentrically arranged bore is made.
  • the eccentric pin 13 is held in the bore 12 by means of a press fit.
  • a radial roller bearing 14 is pushed onto that part of the eccentric pin 13 which projects from the bore 12.
  • the rolling bearing fits into the eccentric guide 15 or guideway with little play.
  • the eccentric guide 15 is directly in the ram 3 let in.
  • the eccentric guide As is known, a circular movement can be broken down into two sinusoidal, oscillating movements in the vertical and horizontal directions.
  • the vertical component is used to move the ram and the tool attached to it, while the horizontal component is received in the guideway and makes no contribution to the power transmission of the tool to the workpiece.
  • the guideway for the eccentric bolt is straight and horizontal and is either open by an upper and lower slide plate or a closed guideway. In the starting position, the eccentric is in the top dead center position and the tappet in the top stroke position, the eccentric pin being in the middle of the guideway.
  • the eccentric guide or guideway 15 has a lower guide area 16 which curves in a circular upward direction from the center with respect to the entire horizontal displacement area and an upper guide area 17 which runs horizontally in the opposite direction from said center.
  • the total stroke of the tool is predetermined by the movement of the eccentric pin 13 and is twice the distance a between the axis of the eccentric shaft 10 and the axis of the eccentric pin 13. At this distance a, the axis of the eccentric pin 13 also moves from the center of the guideway to both sides . From top dead center at The rolling bearing 14 now rolls to the right on the lower curved guideway region 16.
  • the plunger in which the guideway is embedded is additionally moved downwards by the distance b, namely the distance by which the point of contact of the roller bearing has moved vertically upwards from the lowest point 18.
  • the radius of curvature of the lower curved guideway area is larger than the diameter of the rolling bearing 14 rolling in the guideway.
