Description
Technical field
The present invention relates to the manufacture method of the commutator of electric rotating machine, particularly relate to the manufacture method of the commutator segment in the platypelloid type commutator of disc type.
Background technology
In recent years, in the motor that uses, the motor of employing platypelloid type commutator (flat commutator) has appearred by the requirement of equipment miniaturization in driven steering device and engine starter, petrolift etc.This platypelloid type commutator is different with general commutator cylindraceous, has the brush sliding surface of the plate-like of radially extending from axial rotary, and is one-body molded metal parts that calls the commutator metal and synthetic resin.After one-body molded, the commutator metal is cut to radial and circumferentially separately, forms a plurality of commutator segments to become the mutually insulated state.In addition, brush from axially with the brush sliding surface sliding contact that constitutes by this commutator metal, carry out the switching of armature supply.
Adopt the parts that each commutator segment is used to carry out independent cold forging and along sending punch press to form the method for circular hormogon as the manufacture method of the commutator metal of this platypelloid type commutator.But,,, exist the curved surface (R) that makes crooked bight to become big problem by processing such as bending ram and attenuate, stretchings if adopt this mode.When the R in the bight becomes big, the length of brush sliding surface is partly diminished at R, guarantee aspect the sliding surface length unfavorable.In addition, bight R can produce the component that makes commutator segment come-up direction to resin pressure when mold pressing resin.In addition, because the commutator metal increases installation cost by the suitable multinomial operation manufacturing of sending the complexity of punch press of needs, in order to ensure carrying pilot hole that the blank area is increased, make stock utilization decline so simultaneously.
The key diagram of the bight influence when Fig. 6 is the expression mold pressing resin.As shown in Figure 6, the resin of supplying with from cast gate 51 at bight R will flow to brush sliding surface 54 sides from the bight 53 of commutator metal 52.Like this, be out of shape upward by this pressure commutator metal 52, resin might drain to the internal side diameter of brush sliding surface 54.Sew if produce resin, not only need to remove the burr on the brush sliding surface 54, and also will carry out cut for removing the injustice that between commutator segment, produces by burr.For this reason, exist in the problem that the workload of operation behind the mold pressing resin increases and raises the cost.Particularly in as the commutator metal of stamping products, also may produce flow of metal, need take to prevent to sew the measure of resin by the elasticity recovery distortion.
In addition, also tried the manufacture method of the commutator segment that the employing trying hard to address the above problem uses in common cartridge type commutator.Fig. 7 is the side view of the part section of expression cartridge type commutator formation, and Fig. 8 is the figure that the manufacture method of the commutator segment that uses in Fig. 7 is described.In cartridge type commutator 55, commutator segment 56 suitably cuts the bar that calls the commutator section bar and forms.Commutator section bar 57 is drawing materials made of copper.Form trapezoidal cross-section as shown in Figure 8.Commutator segment 56 is that this commutator section bar 57 is die-cut into the shape that dotted line forms among the figure, and becomes the shape of using in the tubular commutator 55 in Fig. 7.
In addition, if when making, do not produce the such angle R of stamping products yet, do not have the problem of elasticity recovery distortion yet by such commutator section bar 57 at the commutator segment (commutator metal) of platypelloid type commutator.Fig. 9 is the key diagram of expression by the state of the commutator segment of commutator section bar manufacturing platypelloid type commutator.Shown in the dotted line of Fig. 9, if cut out commutator segment 58 from commutator section bar 57, then the end of brush sliding surface 59 can not form R.Thereby resin can not flow into sliding surface 59 yet when mold pressing resin is made commutator segment 58, can reduce the workload of following process.
In addition, if by commutator section bar shown in Figure 9 57 die-cut commutator segments 58, then machined surface becomes brush sliding surface 54.Promptly be that section becomes brush sliding surface 54.For this reason, the surface smoothness of brush sliding surface 54 degenerates, and also will carry out cut again after Punching Technology.Thereby, though reduced the workload after the mold pressing, increased the manufacturing workload of commutator segment, can not realize cutting down cost effectively.In addition and since when forming commutator segment 58 commutator section bar 57 to eliminate part bigger, unfavorable so stock utilization is bad to manufacturing cost.In addition, owing to become brush sliding surface 54 than the soft inner portion in commutator section bar 57 surfaces, so there is the low problem of its case hardness, this also is improved.
The objective of the invention is to be manufactured on easily and cheaply in the mold pressing resin operation of platypelloid type commutator and can prevent the commutator segment that resin is sewed, strive reducing the manufacturing workload of platypelloid type commutator.
