Definitions

  • the invention relates to a method for producing a locking bolt (to be fastened to a door pillar of a motor vehicle, cooperating with a door lock) with a fastening part and a locking part, the fastening part preferably having a screw-in bolt and a screw-in head and the locking part having a locking bolt neck and a locking bolt head which
  • the locking pin neck is provided with a circumferential receiving groove and a plastic sleeve is provided within the receiving groove of the locking pin neck, and the plastic sleeve has been realized by encapsulating the locking head neck (in the area of the receiving groove) with a plastic with a damping effect.
  • locking bolts attached to the door pillars together with the locks provided on or in the doors form the locking units.
  • locking bolts (and locks) are, on the one hand, excluded mass articles that have to be manufactured particularly economically, but on the other hand, motor vehicle parts that are of considerable importance for the safety of motor vehicles.
  • Locking bolts of the type in question come into contact with the actual locking elements of the locks, which are usually designed as fork latches, in the area of the locking head neck each time the doors of motor vehicles are opened and closed.
  • the locking bolts In order to prevent the resulting noise from coming into contact with metal, the locking bolts have a plastic sleeve on the locking bolt neck, which consists of a plastic with a damping effect and is realized by overmolding the locking head neck with the appropriate plastic.
  • the invention is therefore based on the object of specifying a method for producing a locking bolt with which the plastic sleeve thus formed can be detached from the locking bolt neck after the extrusion coating of the locking bolt neck with a plastic, so that the plastic sleeve can be rotated relative to the locking bolt neck.
  • the method according to the invention is characterized in that the plastic sleeve is processed in a walking-rolling manner to release the plastic sleeve from the locking pin neck.
  • Walk-on-roll machining means any mechanical action on the plastic sleeve which is initially firmly seated on the locking pin neck and which leads to the plastic sleeve being released from the locking pin neck. According to the invention, the fact that a plastic can be plastically deformed by mechanical action is thus used.
  • the method according to the invention is preferably implemented in such a way that the plastic sleeve is machined with a driven flexing roller when the locking bolt is freely rotatable.
  • the invention relates to a method for producing a locking bolt 1 which is fastened to a door pillar of a motor vehicle, not shown, and which interacts with a door lock, not shown, namely to together with a lock provided on or in the doors of a motor vehicle forms the locking unit.
  • the locking bolt 1 consists of a fastening part 2 and a locking part 3.
  • the fastening part 2 of the locking bolt 1 has a screw-in bolt 4 and a screw-in head 5 in the exemplary embodiment shown.
  • the locking part 3 of the locking bolt consists of a locking bolt neck 6 and a locking bolt head 7, the locking bolt neck 6 being provided with a circumferential receiving groove 8 and a plastic sleeve 9 provided within the receiving groove 8.
  • the plastic sleeve 9 has been realized by overmolding the closing head neck 6 - in the region of the receiving groove 8 - with a plastic with a damping effect.
  • the plastic sleeve 9 is processed in a walking-rolling manner in order to detach the plastic sleeve 9 from the locking bolt neck 6.
  • the plastic sleeve 9 is machined with a driven rotating roller 10 when the locking bolt 1 is freely rotatable.
