Definitions

  • the invention relates to a method for producing a one-piece lock holder according to the preamble of claim 1 and a lock holder produced by this method.
  • lock holders in question are found in particular in locking systems such as motor vehicle locks and locks.
  • locking systems such as motor vehicle locks and locks.
  • the invention will be explained with reference to the field of application of the motor vehicle locks, which, however, is not to be understood as limiting.
  • a lock holder usually consists of a base plate and a lock bracket, also called latch bolt or lock holder bracket.
  • the base plate typically has recesses, for example in the form of bores, in order to enable, for example, attachment of the lock holder to a body of a motor vehicle.
  • the lock bracket is formed such that a recess is present in the middle, so that the lock bracket in the installed state interacts with a lock or a lock.
  • the lock holder in the closed state of a motor vehicle door or flap in holding engagement with a catch of a lock o. The like. Stand to shoot a flap or door of a vehicle safely.
  • a lock of a motor vehicle generally has a locking mechanism comprising a catch and at least one pawl, with which a rotation of the catch in the opening direction can be blocked.
  • the publication DE 10 2010 024 510 A1 discloses a method of manufacturing a lock holder in which a raw material is first sheared off and then hot worked to processing temperatures above the recrystallization temperature and formed into a lock holder by pressure forming by forge hammers.
  • the publication DE 10 2010 011 716 A1 discloses a method of manufacturing a lock holder in which a T-shaped semifinished product is formed by cold extrusion from a raw material.
  • the lock holder can be formed from a round stock by massive forming into a T-shaped stock.
  • the T-shaped semifinished product is further processed, for example by cold punching to provide retaining holes in the base plate and a recess in the lock bracket.
  • the method is designed to save a costly reworking of the lock holder.
  • the forming process by plastic change of a given fixed starting blank is basically associated with the problem that high forming forces are required, which at the same time have a high tool stress result. Furthermore, appropriately sized machines such as presses are required to provide the high forming forces.
  • a lock holder is formed from a metallic starting blank by cold heading.
  • the starting blank is formed essentially block-shaped or cylindrical before the forming process and is reshaped such that a cold hardening of the lock holder takes place.
  • a shape-changing shape of the starting blank that is close to the final shape preferably takes place.
  • the reshaped starting blank after the forming process then substantially corresponds to the final shape of the lock holder.
  • Notches e.g. in the form of holes on the base plate and the recess in the lock bracket can in principle be formed depending on the requirements already in the forming process or in a post-processing, for example by punching or cutting.
  • Essential is the consideration to make the transformation of the starting blank to a one-piece lock holder with a substantially block or cylindrical starting blank in order to form a stress-resistant lock holder in a targeted manner, which also can be produced advantageously also manufacturing technology.
  • a targeted adjustment of the mechanical properties of the lock holder which lead to very specific application properties of a lock holder produced in this way.
  • the cold forming also causes an increase in strength, also called strain hardening.
  • materials can be used for the starting blank, which have a low strength in the original state and can be subjected to higher stress as a formed lock holder due to work hardening, without the need to use high-quality materials as the starting blank.
  • the forming forces required for the cold forming can be deliberately reduced, so that the high tool stresses are advantageously minimized.
  • the machines required for the production, such as presses, can be suitably dimensioned smaller, so that an overall optimized production is made possible.
  • the forming of the blank is done by cold heading.
  • the starting blank is largely utilized in such a forming process, so that large material savings are possible, in particular compared to machining processes.
  • the starting blank is therefore preferably equal in volume to the formed lock holder.
  • cold heading enables particularly short production cycles, even for complex molded parts, since the entire blank volume is reshaped near the end of the mold at the same time or in several forming stages.
  • a wire or a profile wire is used as the starting blank, preferably with a cross-sectional area of 450 mm 2 to 1125 mm 2 .
  • wires or profile wires can be processed in a simple manner by shearing or sawing suitable.

  • the diameter is preferably 15 mm to 35 mm.

  • the main shape change during the forming process is substantially perpendicular to the cross-sectional area or to the profile surface of the starting blank.
  • the cross-sectional area or profile surface is basically defined by the width and the length, with essentially cylindrical starting blanks through the diameter.
  • the main shape change significantly affects the solidification effect during forming, so that the work hardening of the lock holder is suitably optimized in this way.
