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.
- FIG. 1 is an example of a substantially unedited one Raw material 1 shown.
- This raw material 1 is exemplary represented as a flat, solid disc, which by a round bar material is sheared off and formed. If necessary, deviations from FIG. 1 cannot be specified raw material shown are taken as starting material, which is designed for example as an annular disc and already has a prefabricated central opening 14 'like this is indicated in Figure 1 with a broken line.
- the basic body of raw material 1 can alternatively be stamped out a strip material with or without a hole can be obtained. If a thick-walled tube-rod material is used as the starting material takes, as the raw material 1, the disc in the form of a round blank available.
- raw 1 can be used in the method according to the invention and it will only as an example of a solid material in the form of a Disk out for explanation below. Possibly can also from such a solid material disc Ronde can be obtained by having a central opening punched out as a kind of preprocessing step (not shown).
- connection elements 2 protrude radially over the peripheral edge of the Raw material 1 according to Figure 1 as individual connection elements 2 before and these are shaped in such a way that, as in FIG is shown, have their finished contour and size. 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.
- the raw material 1 are annealed, and after The connecting elements 2 according to FIG. 2 are then cooled with Finished contour and size shaped.
- these can be used individually or the entire base body shown in FIG. 2 again be annealed.
- FIG. 3 shows a commutator blank 3, which one by cold forming starting from the body according to FIG. 2 receives.
- This blank 3 is cup-shaped and has a substantially cylindrical shell 4 and one in essential plan floor 5.
- internal anchoring elements 6 formed, which is ring-shaped on an inner surface 7 of the Bottom 5 of the pot-shaped blank 3 are arranged. How shown, these inner anchoring elements 6 run in essentially axially related to the blank 3 and stand jagged from the inner surface 7 of the bottom 5 at a distance Way forward.
- the forming process is based on the figure 2 to the pot-shaped blank 3 according to FIG. 3, preferably in a single forming step. Of course they can Forming processes, if necessary, also one after the other be performed.
- each recess 9 goes from a free edge 10 of the cylindrical shell 4 and extends close to Bottom 5 of the pot-shaped blank 3.
- the recesses 9 are therefore V-shaped trained and expediently in the apex area a straight line segment.
- each V-shaped recess 9 can be narrow, web-shaped trained and radially extending recesses 16 formed which are assigned to the segment division and are in Direction of the center of the bottom 5 on its inner surface 7 extend.
- the advantage of these recesses 9 and possibly the recesses 16 will be explained later.
- the shape of the recesses 9 and, if appropriate, the narrow, radially extending recesses 16 can with all other forming operations in one step be, so that you start from that shown in Figure 2 Body in one step that shown in Figure 3 receives cup-shaped blank 3 for the commutator.
- a base body 12 shown in Figure 4 in which it is an intermediate product made of a conductive material is involved in commutator manufacturing.
- This base body 12 has external anchoring elements obtained by cold working 13, which in the vicinity of the free edge 10 of the jacket 4th are formed radially jagged inward.
- a central one Opening 14 punched out in the bottom 5 of the pot-shaped blank 3 become.
- This central opening 14 is located radially in the base 5 within the ring-shaped arrangement of internal anchoring elements 6.
- the inner anchoring elements 6 slightly radially bent outside to improve its anchoring effect.
- Base body 12 as an intermediate product in the production of commutators can be reshaped and shaped, of course Edits can also be made one after the other. If you start from a raw material (not shown), which already has a central opening 14 ', can of course the punching process according to FIG. 4 is omitted. These the central opening 14 shown is then already present, which for the inclusion of a rotor shaft no closer electrical machine shown is determined.
- the commutator can then completely be completed that one in the interior of the pot-shaped Filled and pressed 3 blank insulating material, which with Help the inner anchoring elements 6 and the outer Anchoring elements 13 reliably anchored to the base body 12 is. If necessary, tinning can be carried out become. Starting from the flat, continuous outer surface 15 the bottom 5 are then used to separate and subdivide the Segments introduced on the commutator cut, only one Depth of cut approximately the material thickness of the bottom 5 required is because the recesses 9 are already used to separate the segments on the segment dividing lines on the cylindrical jacket 4 have been formed. This simplifies the subsequent cutting processing in a noteworthy manner. If additionally the narrow, radially extending depressions 16 are formed, the depth of cut can be further reduce so that they are even smaller than the basic material thickness of the bottom is 5. In addition, a tour of cutting processing for segment division and separation can be achieved.
- Such a commutator is then used electrical lines on the preferably flag-shaped trained connecting elements 2, which for example around the connection elements in one or more turns be wrapped. Then the connection elements 2 in Direction to the outer surface of the cylindrical shell 4 bent back. This bending process can be done easily and make crack-free, since the connecting elements 2 thanks to the invention Manufacturing in a ductile or bendable Condition with undisturbed fiber orientation. Such a Completed commutator is then, for example, in a electrical machine installed.
- the insulating material base body 12 it is also essential that the insulating material base body 12 to be filled exclusively by Forming from a raw material from conductive Material is manufactured, and that all of these forming operations yourself with the smallest possible number of work steps can be carried out, in a targeted manner, apart from the connection elements 2, which are used in cold forming caused material consolidation to increase the Strength of the base body 12 is used.
- the flat commutator should in particular be the outer surface 15 the bottom 5 to be resistant, for example on this the brushes of an electrical machine are running.
- the connecting elements 2 in a material-saving manner, as they are directly shaped in the finished shape and size be without having an annular flange on the free edge 10 of the cylindrical shell 4 of the cup-shaped blank 3 required.
- the basic material costs to be used for the Production of such a commutator reduce the Economy of the production method according to the invention increase overall.
