Description
Technical field
The present invention relates to the optimization method of the stator manufacturing motor generator.The present invention more preferably relates to the method for making the groove distortion be arranged in blade, described blade is for the manufacture of the stator of electro-motor, wherein said method is by radially moving hole punch element and realize, and described hole punch element is directed by the action of some wedges activated by the vertical movement of the tup of mechanical compression device.
In addition, the present invention relates to the system for making groove be out of shape, described groove participates in being used for the production of blade of the stator manufacturing motor generator.
Background technology
Motor generator is the equipment that setting is used for carrying out power conversion is well-known in the art, and especially, motor such as electro-motor can convert electric energy to mechanical energy, or on the contrary, the function that such as generates electricity converts mechanical energy to electric energy.These equipment are formed by removable or fixing induction core usually, and the function of wherein said equipment is based on the electromagnetic induction produced by the interaction between induction coil.
As is known for those skilled in the art, fixed core is arranged and is contained in stator body, and mobile core is disposed in rotor subject, the interaction energy between described fixed core and mobile core produces is enough to the magnetic field making rotor motion, and therefore converts electric energy to mechanical energy.
According to structural viewpoint, the stator of motor generator primarily of metal frame and multiple coil (around fluted disc around electric conductor) integrated, wherein said coil is arranged to aim at metal frame.
More specifically, and according to structural viewpoint, metal frame according to the stator of conventional structure of the prior art limits radial teeth, and described radial teeth each other circle separates, and connects (wherein lower end is spaced) by their upper end is circumferential each other.Therefore, these teeth finally limit the structure that electric conductor coils, and the gap between described tooth has the function holding the volume formed by electric conductor.
In this case, its corresponding coil of each tooth can be observed and form fixing induction core.
In Special rotary motor generator, rotor (physical structure of rotor is similar to the physical structure of stator) is assembled in the inside of stator, and therefore the length dimension of the tooth of stator metal frame is configured to form central space, described gap is used for holding and location rotor.
Fig. 1 shows the schematic vertical view of the stator vane of the motor generator of the conventional structure according to prior art.
According to above-mentioned basic principle, for a person skilled in the art, it be obvious that the stators and rotators of same motor generator can be obtained by same metallic plate, and this is because the size of rotor is substantially equal to the size of the central space of stator.But also as known to the person skilled in the art, process metal derby comprises complicated industrial process, and this can produce insecure quality.
In this sense, generally can observe, except the corresponding rotor metal frame of motor stator, the stator metal frame of motor generator of the prior art usually has the multiple layer metal blade of same size by attaching and produces.Can noticing an example of this structure in document US 2011/0127876, wherein illustrate and describing when carrying out stamping procedure, elemental metals plate (raw material) may be used for manufacturing multiple blade of stator and multiple blades of rotor.Wherein further highlights rotor blade to be made by the raw-material redundance that obtains after utilizing punching press stator vane.Although described document US 2011/0127876 describes an example of such structure, should confirmedly be that just described this practice has been considered to conventional from generation nineteen sixty.
According to theory extensively universal in prior art, it is known that the area of the electric conductor of formation stator coil comprises the characteristic that can affect dynamoelectric and power generation engine efficiency.More specifically, except the inherent limitations of the rated value of the electric current carried except these conductors, the area of electric conductor is less, and it is known for more easily producing Joule effect.Therefore, research and development have the electric conductor of the formation stator coil of larger possible area is noticeable (considering the needs of each design).
But the area forming the electric conductor of stator coil can be limited by the characteristic of the metal frame of stator.
In this sense, each tooth of stator vane all has by the final end of two flanks restrictions is known.Therefore, the area of electric conductor of composition stator coil is present in the gap restriction between the flank of continuous print tooth, and the operation wherein wire being inserted stator is limited by this gap between flank.
Described gap between the flank that should further be mentioned that continuous print tooth also comprises the characteristic that can affect dynamoelectric and power generation engine efficiency.
This is that the leakage field then responding to core is larger because in fact this space is larger, and the therefore loss of motor generator larger (relate to the quantity that electric energy converts mechanical energy to, or mechanical energy converting the quantity of electric energy to).
Therefore, in order to provide efficient motor generator, must make balance between the area of electric conductor forming stator coil and the leakage field of induction core, described leakage field is enhanced by the gap between the flank of continuous print tooth.But it is extremely complicated for obtaining this balance.
In order to optimize these factors, also have the stator vane of following motor generator in prior art, the flank of the tooth of described stator vane is allowed " movement " in the process manufacturing said stator.Described by the example of these blades and/or manufacture method has in document BR 9702724, US 4176444, US4267719 and US 6742238.
Document BR 9702724 describes the structure of the optimization of the stator vane of motor generator.In such an embodiment, in the process manufacturing stator, the flank of tooth can be adjusted, and therefore makes accommodation passage " opening " and " closing " of electric conductor.More specifically, it should be noted that " opening " and " closing " of this passage realizes by making the flank of tooth be out of shape.The main passive aspect relating to the structure described in document BR 9702724 relates to needs to make the flank of tooth to be out of shape, with closed channel with in access portal, this is owing to confirming that by multiple blade grouping be extremely complicated, and the flank of described blade tooth is by pivotable.
Document US 4176444 and US 4267719 includes same priority, and describes the method and apparatus forming motor stator.Mentioned method provides multiple step, generally defines first punching press blade in described step, then vane group is combined the metal frame forming stator.Once metal frame is formed, the flank of tooth will withstanding pressure distortion, and due to all passages be all opening, therefore realize the layout of electric conductor.Then, passage is closed by pressure distortion, and the method terminates.Usually, " opening " is implemented by the device comprising hole punch element in the channel, and wherein hole punch element is inserted in each passage, and each lower end of tooth is all bearing in the distorted pattern of a type.The movement (from inside to outside) of hole punch element orders about the flank of tooth against template, and therefore described flank has the shape of template.
Although the main content section of these documents solves in the main contents of document BR 9702724 the passive aspect existed in prior art, it should be noted that the opening procedure of passage is only by using complicated instrument to realize.In addition, attested is that all flanks of tooth are subject to uniform pressure; But the identical flank of tooth has the mechanical resistance of different proportion, this can cause finally occurring crack in process.
Document US 6742238 describes following mechanical theory, wherein stator vane has been stamped and has had open channel (for holding electric conductor), namely the punching template of this blade makes stator vane " be exerted pressure " by single to form, comprise the flank " distortion " making tooth.Although this theory solves the subject matter of the conventional steps relating in the accommodation passage of electric conductor " opening ", but should also be noted that the redundance obtained after the punch steps of these stator vanes can not be used to manufacture rotor (same motor generator), this be the external diameter of internal diameter with rotor owing to making stator equal be extremely important, and the mechanical theory that document US 6742238 describes could not realize this requirement.
