Definitions

  • the invention relates to a device for bending a split pin.
  • a split pin is a securing element that is used to secure the position of connected components. For example, nuts, in particular castle nuts, can be secured against unwanted twisting with a split pin. To prevent the split pin from slipping out, the ends of the split pin can be bent over. This can be done using a hammer, for example, to hit the ends of the pin.
  • the JP S63 136881 U discloses a split pin bending tool.
  • the cotter pin bending tool has, as main components, a socket, a bending handle, a long leg bending section and a short leg bending section.
  • the DE 20 2014 008807 U1 discloses a device for pinning and de-pinning a slotted pin.
  • a carrier has at least one positioning means in relation to an element which has a channel for the pin.
  • a support means is intended to form a support for an end section of a part or leg of the pin upon deformation of the end section.
  • the JP S60 84271 U also discloses a split pin bending tool for opening and bending a leg portion of a split pin inserted and attached to the mounting portion.
  • the invention is based on the object of providing an (alternative) device for bending a split pin, with which a reliable bending of the split pin ends is made possible, in particular to secure a castle nut against rotation, while maintaining the quality of work.
  • the device (split pin bending tool) is used to bend a split pin to secure a workpiece in position, in particular to secure a nut, preferably a castle nut, against rotation.
  • the device has a tool body and a holding component for holding the split pin during a bending process (the split pin).
  • the holding component is rotatably mounted on the tool body.
  • the device has a bending element.
  • the bending element is arranged on the tool body in such a way that one end of a split pin held on the holding component can be bent over by a relative rotation between the holding component and the tool body on the bending element, in particular flush with the workpiece.
  • the relative rotation between the holding component and the tool body (and thus between the split pin held in the holding component and the tool body) enables the split pin ends of a split pin to be bent over reliably and quickly while maintaining the quality of work. Since no hammer has to be used, the risk of injury is reduced and the component to be secured cannot be damaged by the hammer.
  • the device can in particular bend the ends of a split pin.
  • an axis of rotation of the holding component can run inclined, preferably perpendicular, to a longitudinal axis of the tool body.
  • the tool body can in particular have a boom for the rotatable mounting of the holding component.
  • the bending element can in particular be arranged at one end of the tool body.
  • the bending element can in particular be fixed or attached in a stationary manner with respect to the tool body, preferably an arm of the tool body.
  • the split pin can have two legs that are connected via a split pin head.
  • the two legs of the split pin can preferably be of different lengths and together form a round cross section.
  • the split pin head can preferably be designed as an approximately circular loop.
  • the split pin can be designed as a standard split pin according to DIN EN ISO 1234.
  • the split pin can be of any size.
  • the cotter pin can preferably have a length which is greater than or equal to 100 mm and / or a diameter which is adapted for a bore diameter of 8 mm or greater (so-called 8 mm cotter pin or greater).
  • a first cotter pin end of the cotter pin can be bent over on the bending element by a relative rotation between the tool body and the holding component in a first direction of rotation.
  • a second cotter pin end of the cotter pin can be bent over on the bending element by a relative rotation between the tool body and the holding component in a second direction of rotation which is opposite to the first direction of rotation.
  • the holding component holds the split pin on a split pin head of the split pin.
  • the holding component has a holder for holding a split pin head of the split pin.
  • the holder can in particular be designed as a pin or projection.
  • the holding component can be secured against rotation on the workpiece during the relative rotation between the holding component and the tool body. This enables a relative rotation between, on the one hand, the workpiece (nut, castle nut), the split pin and the holding component and, on the other hand, the tool body and the bending element.
  • the holding component is designed to interlock with the workpiece, which is designed in particular as a nut, preferably a castle nut, in order to secure the holding component in a rotationally fixed manner on the workpiece.
  • the holding component has at least one fastening element for securing the holding component in a rotationally fixed manner on the workpiece.
  • the at least one fastening element is designed to engage in at least one recess in a crown section of the workpiece designed as a castle nut.
  • the retaining component can thus be held securely on the castle nut during the bending process of the split pin.
  • the holding component is designed as a turntable.
  • the turntable can in particular have an outer wall area designed as a ring segment section, in particular a half ring segment section.
  • the outer wall area can extend from a plate area of the holding component as a projection, in particular in a direction parallel to a central axis and in a circumferential direction around the central axis of the holding component.
  • the outer wall area is arranged on a side of the holding component facing away from the bending element.
  • the outer wall area is designed to partially encompass the workpiece, in particular the castle nut.
  • the outer wall region has a recess for the passage of the split pin, in particular a split pin section adjoining a split pin head of the split pin.
  • the holder and / or the recess is arranged on a side of the holding component facing away from the bending element.
  • the holding component is slidably mounted on the tool body, so that in particular a distance between the holding component and the bending element can be changed.
  • this can enable adaptation to the given geometry of the workpiece and the split pin.
  • this can make it possible to position the bending element as close as possible to the workpiece, so that the split pin ends can be bent so that they are flush with the workpiece.
  • the tool body has an elongated hole in which the holding component is slidably mounted, so that in particular a distance between the holding component and the bending element can be changed.
  • the device also has a mechanism for converting a pivoting movement between two handle parts of the tool body to a translational movement of the holding component, in particular in a direction towards or away from the bending element.
  • the bending element can be positioned close to the workpiece in a simple manner, so that the ends of the split pin can be bent so that they are flush with the workpiece.
  • the bending element can be removed from the workpiece and the cotter pin held in the holding component in order to make it easier to put on and remove the device.
  • the holding component is connected to a push rod for moving the holding component.
  • the tool body has a first handle part and a second handle part which is pivotably connected to the first handle part. A pivoting of the second handle part to the first handle part causes a displacement of the holding component to the bending element by means of the push rod.
  • the bending element is designed as a pin, which preferably has a bending edge and two, in particular, flat bending surfaces that are connected to one another via the bending edge.
  • the fastening elements can extend radially inward to a central axis of the holding component and / or be designed as pins.

  • the castle nut 2 also has a crown portion 7 with several spaced apart recesses 8 (six recesses in the example of Figure 1 ) to lead through the split pin 4.
  • the castle nut 2 can additionally have a main body section 10 which is designed as an external hexagon.
  • the split pin 4 has a split pin head 12, a first leg 14 and a second leg 16.
  • the split pin head 12 connects the first leg 14 and the second leg 16.
  • the first leg 14 and the second leg 16 are of different lengths.
  • the first leg 14 and the second leg 16 can jointly define a round cross section.
  • the split pin head 12 has a substantially circular loop shape.
  • the split pin 4 can in particular be a standard split pin according to DIN EN ISO 1234.
  • the split pin 4 can be used to connect the castle nut 2 to the threaded rod 6 in a rotationally fixed manner.
  • the first and second legs 14, 16 of the split pin 4 can be guided through two recesses 8 of the crown section 7 and a transverse bore through the threaded rod 6.
  • the respective ends of the legs 14 and 16, which are opposite the split pin head 12, can then be bent over to secure the split pin 4.
  • the ends of the cotter pins are bent so that they rest against the outer peripheral surfaces 7A and 7B.
  • the cotter pin ends of the legs 14 and 16 can be worked for bending, for example with a hammer. This goes hand in hand with a risk of injury from using the hammer and different qualities when bending the ends of the pin.
  • the Figures 2 and 3 show a device 18 for bending the ends of a cotter pin in two different views (from obliquely above and obliquely from below).
  • the device 18 has a holding component 20, a tool body 22, a push rod 24 and a bending element 26.
