Definitions

  • the invention is concerned with a method of manufacture a commutator, in particular a flat commutator, for electrical machines according to the preamble of claim 1.
  • a radially protruding outward Formed ring flange namely by material displacement in the axial direction against the free end of the jacket there.
  • the flags are now in the shape of a flag trained connecting elements by punching out of the Preserved ring flange. With this punching process the outer anchoring elements are also split off.
  • Another difficulty is the fact that the various extrusion treatments and also during training of the ring flange inevitably through the forming one Material consolidation is effected so that the formed Connection elements less ductile or bendable than the starting raw material are. After the completion of the commutator but connecting wires are wound around these connecting elements and then the connectors are on the outside of the cylindrical jacket bent back. As a result of material embrittlement are therefore cracks in the usual production method occurred and these are generally to be feared. Also includes the known manufacturing process a variety of individual Deformation steps, including the economical production method such commutators suffer.
  • the object of the invention is under Overcoming the difficulties outlined above Method for producing a commutator, in particular one To provide face commutators of the generic type, which is an economical and material-saving manufacture permitted, and in particular the connection elements after the formation are ductile or bendable and until implementation remain bendable during the bending process.
  • this is a method of manufacture a commutator, in particular a flat commutator, for electrical machines provided, which consists of an im essential raw raw material made of conductive material forming several, isolated from each other and Isolierstoff comprehensive segments with assigned, radially from the segments individually protruding connecting elements is, whereby the manufacturing process distinguishes that the raw material first for the formation of the individual connection elements with finished contour and size as well is formed with the finished ductile state.
  • connection elements formed by material displacement. It is essential here that these connection elements this forming process have their finished shape and size and in a ductile finished state, which up to final bending processing is retained.
  • subsequent processing operations such as free cutting and the like, avoided since the connection elements thus formed already have their finished contour and - have size.
  • the method according to the invention also falls no waste material because there is no continuous ring flange is formed, but only the individual flag-shaped Connection elements, which are in the radial direction on the outer edge protrude from the raw material body.
  • connection elements are ductile or bendable because they are ahead of the subsequent ones Forming processes were formed and no deformation more exposed, which leads to material hardening or embrittlement.
  • inventive method a commutator economical and Made to save material.
  • the raw material before forming to form the connection elements in Dependence on the selected raw material or raw material heated in such a way that there is a notable strain hardening of the material avoid when designing the connection elements leaves.
  • This allows the ductility of the formed Improve connection elements and their ductility depends essentially depends on the properties of the raw material.
  • connection elements in the so heated state of the raw material, one such Treatment called warm presses, so that the raw material passed to the press immediately after heating and the shape of the connection elements while still warm he follows.
  • the material can be formed if necessary Forging and / or at forging temperature.
  • connection elements are shaped in the warm or warm area.
  • the raw material is heated to a temperature in a range from about 300 to about 700 ° C.
  • An alternative manufacturing method to train the individual Connection elements with finished contour and size as well as with ductile Finished state is characterized in that the raw material annealed before forming to form the connecting elements is formed, the connection elements by cold forming be followed by another annealing treatment. In this way it can also be avoided, for example, that the connection elements after the formation by the Forming caused material hardening and embrittlement become less ductile.
  • a method of manufacture time consuming, since after the annealing treatments Cooling times must elapse.
  • the segment division is expediently assigned Recesses, starting from the free edge of the jacket, through Material displacement formed by cold forming.
  • This Recesses extend close to the inner surface of the bottom of the pot-shaped blanks.
  • the clear width of the Recess, starting from the free edge of the jacket, in the direction of the soil are getting smaller, and in particular the are through Material displacement trained recesses V-shaped.
  • the "tip area" of the respective V-shaped recess becomes preferably formed by a short straight section. The number of these recesses corresponds to the number of segments of the commutator and they are assigned to the respective divisions.
  • cold forming is used for training of the pot-shaped blank, to form the ring-shaped arranged inner anchoring elements and by Material displacement formed recesses and, if necessary to form the radial recesses in one Work step carried out.
  • the jacket radially inward facing outer anchoring elements for the Insulating material filling formed by cold forming.
  • the inner anchoring elements become slight bent radially outwards to ensure the anchoring effect with the later filled insulation material and the insulation material filling improve.
  • Manufacturing processes are carried out for training purposes the radially inward facing anchoring elements, for punching out the central opening in the bottom of the pot-shaped blank and the bending of the inner anchoring elements radially outwards in one work step.
  • Manufacturing times for such Shorten the commutator considerably, since you can see overall the method according to the invention, for example in essentially only three transformation steps starting from Raw material up to the finished commutator without insulating material filling and post-treatment or post-processing is required.
  • All other processing and treatments such as insertion the insulating material filling, if necessary tinning of the base body and severing the segments by cutting along the Segment divisions and attachment of lead wires to the Connection elements and bending the same can then on be carried out in the usual way.
  • the bending process for the Connection elements is thanks to the manufacturing method according to the invention significantly simplified and cracking due to material embrittlement can be avoided because the connection elements in the ductile condition without material hardening through the forming processes available. Furthermore, an undisturbed fiber course is through the forming process, so that the commutator high can withstand dynamic stresses, in particular occur in motor vehicles.
  • the manufacturing method according to the invention is for manufacturing of commutators of different designs and Types suitable, and the invention is not to manufacture limited by face commutators.
  • Essential to the Manufacturing of all these types of commutators is however the fact that the connection elements on the one hand be formed that there is no waste material, and that on the other hand, these connection elements with finished contour and size and with a ductile finished state right at the beginning of the manufacturing process are formed by material displacement. This material displacement takes place, seen from the raw material base for the formation of the connection elements in the direction outward.
  • the anchoring elements for the insulating material filling be shaped in a correspondingly changed manner without that the protective concept is abandoned according to the invention, according to which the shape of the connection elements directly from the Raw material through material displacement to the finished contour and - size and finished with ductile finished.

Also have these connection elements 2 their ductile finished state.
  • the raw material 1 before the formation of the connection elements 2 depending on the material properties heated so that a notable material forming hardening can be avoided. In this heated state then the connection elements 2 with the finished and final state preferably shaped.
  • Such Forming can be referred to as semi-hot presses, for example become.
  • connection elements 2 that Material of the raw material 1 preferably towards the outside displaced while still warm, and the corresponding Molding tools that are used for this have assigned rooms, which the finished contour and size of the Specify and limit connection elements 2.
  • temperatures required for this depend on the properties of the conductive material used for the Raw material 1, in particular for example of copper alloys, depend, only preferred ranges can be specified. It has been shown that heating to a temperature of about 150 ° C is appropriate. This temperature can of course, be higher. In a preferred manner, a Temperature range from about 300 to about 700 ° C result.
  • connection elements 2 there is also cold forming the connection elements 2 into consideration.
