Abstract
The invention discloses a dot overlapping and riveting mould of a motor stator core, which comprises an upper mould base, a lower mould base, a fixed plate, a discharging plate and a plurality of guide columns. The upper mould base is connected with the fixed plate. A metering male mould, a buckling male mould and a blanking male mould are arranged on the fixed plate. A metering female mould, a buckling female mould and a blanking female mould are arranged on the lower mould base. The metering female mould, the buckling female mould and the blanking female mould respectively correspond to the metering male mould, the buckling male mould and the blanking male mould of the upper mould base. The upper mould base and the lower mould base are connected through the guide columns. By means of the mode, the dot overlapping and riveting of the motor core can be completed; furthermore, the overlapping and packaging efficiency is high.
Description
Technical field
The present invention relates to mould applications, particularly relate to a kind of diel that is used for the folded riveting of motor stator core.
Background technology
Iron core is one of strength member of motor, and generally high by permeability, the low silicon steel sheet of loss is processed.In order to reduce loss, iron core by several to hundreds of sheet silicon steel sheet on its axis direction fixed with each other form as a whole.Want closely between the silicon steel sheet of iron core, the quality of iron core closed assembly quality will be directly connected to performance of products.
Folded riveting mode commonly used is the folded riveting of " V " shape, and it is protruding promptly on silicon steel sheet, to extrude " V " shape earlier, then each sheet silicon steel sheet is forced together.The diel that is used for the folded riveting of " V " shape generally need be pressed silicon steel sheet once with frock clamp after closed assembly again, guarantees that the gap of closed assembly meets the requirements.Therefore, the diel operation of the folded riveting of " V " shape is more, and make efficiency is lower.
Summary of the invention
The technical problem that the present invention mainly solves provides the folded riveting mould of a kind of motor stator core round dot, can realize that round dot folds riveting.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: provide a kind of motor stator core round dot to fold the riveting mould; The folded riveting mould of said motor stator core round dot comprises upper bolster, die shoe, fixed head, stripper and a plurality of guide pillar; Upper bolster links to each other with fixed head; Be provided with the metering punch and metering die of the folded riveting thickness of control between upper bolster and the die shoe, go out the button point punch and button point die of circular riveting point, and with folded riveting blanking punch and the blanking die together of silicon steel sheet.
In preferred embodiment of the present invention, has backing plate between said upper bolster and the said fixed head.
In preferred embodiment of the present invention, the guide pillar quantity of the folded riveting mould of said motor stator core round dot is four.
In preferred embodiment of the present invention, said guide pillar is the ball guide pillar.
The invention has the beneficial effects as follows: the folded riveting mould of motor stator core round dot provided by the invention can realize that round dot fold riveting, and the make efficiency height.
Description of drawings
Fig. 1 is the silicon steel sheet sketch map of motor stator core of the present invention;
The structural representation of folded riveting mould one preferred embodiment of Fig. 2 motor stator core round dot of the present invention;
The mark of each parts is following in the accompanying drawing: upper bolster 1, die shoe 2, backing plate 3, fixed head 4, stripper 5, metering punch 6, metering die 7, button point punch 8, button point die 9, blanking punch 10, blanking die 11, band material 12, silicon steel sheet 14, round dot protruding 15.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, Fig. 1 is the silicon steel sheet sketch map of motor stator core of the present invention.Have three round dots convexities 15 above the said silicon steel sheet 14, motor stator core is formed by the folded riveting of silicon steel sheet 14 a slice a slices.Round dot 15 is protruding for folding the riveting point.With respect to the folded riveting of " V " shape, the gap between the silicon steel sheet 14 can be better controlled in the folded riveting of round dot, and the iron-core magnetic induction loss that folded riveting forms is lower.
Please will introduce the folded riveting mould of the motor stator core round dot that is used for the said iron core of closed assembly below simultaneously with reference to figure 2.The folded riveting mould of said motor stator core round dot comprises: upper bolster 1, die shoe 2, stripper 5, a plurality of guide pillar and stamping-out assembly (not illustrating); Upper bolster 1 links to each other with fixed head 4; Fixed head 4 is provided with metering punch 6, button point punch 8 and blanking punch 10; Die shoe 2 is provided with metering die 7, buckle some dies 9 and blanking die 11, and above-mentioned metering die 6, button point die 9 and blanking die 11 are corresponding with metering punch 6, a button punch 8 and the blanking punch 10 of upper bolster 1 respectively.Metering punch 6 with measure the thickness that die 7 is used to control the electric machine iron core that silicon steel sheet 14 closed assemblies become.Be connected through guide pillar between upper bolster 1 and the die shoe 2.The stamping-out assembly according to the shaped design of the silicon steel sheet 14 that requires to cut.Guide pillar can be positioned near four angles of the folded riveting mould of said motor stator core round dot.When the folded riveting mould of motor stator core round dot is started working; Band material 12 gets into the folded riveting mould of motor stator core round dot; In the stamping-out process; It is protruding 15 that the folded riveting mould of said motor stator core round dot can stamping-out go out satisfactory silicon steel sheet 14 and round dot, and the shaping of its orbicular spot protruding 15 is by the completion that matches with a button point die 9 of button point punch 8, and silicon steel sheet 14 is under the effect of blanking punch 10 and blanking die 11 then; The round dot of silicon steel sheet 14 protruding 15 since extrusion friction power up and down silicon steel sheet 14 be buckled together, the iron core that closed assembly is good is at last folded the riveting mould from said motor stator core round dot under the effect of stripper 5.A motor stator core completes.The folded riveting mould closed assembly speed of said motor stator core round dot is fast, need not extra frock clamp and carries out subsequent job.
In another embodiment, have backing plate 3 between said upper bolster 1 and the said stripper 5, be connected through four guide pillars between upper bolster 1 and the die shoe 2.In order to improve the precision of mould, said guide pillar can be the ball guide pillar.
The folded riveting mould of motor stator core round dot of the present invention is used for the folded riveting of round dot of electric machine iron core, and a mould can be accomplished the closed assembly of iron core, need not extra frock clamp and carries out subsequent job, and it is high to have closed assembly efficient, makes advantage of high precision.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
