Description
Technical field
The invention belongs to die apparatus technical field, more particularly, to a kind of automatic viscose glue lamination high speed stamping of electric machine iron core
Progressive die.
Background technology
Stamping die -- in Cold Press Working, material (metal is nonmetallic) is processed into one kind of part (or semi-finished product)
Special process is equipped, referred to as cold punching die (being commonly called as cold-punching mould).Punching press -- it is at room temperature, using on forcing press
Mould applies pressure to material, it is produced separation or is plastically deformed, so that a kind of pressure processing method of part needed for obtaining.
Diel is the essential technological equipment of punching production, is technology-intensive product.The quality of stamping parts, life
Efficiency and production cost etc. are produced, has direct relation with mold design and manufacture.The height of Mould design and manufacturing technical merit,
It is to weigh one of important symbol of a national product manufacture level height, largely decides quality, the effect of product
The development ability of benefit and new product.
Existing in the market electric machine rotor iron core is formed by stacking by mould punching in piece, and tool locating is used after manually reason piece
Argon arc welding welding is completed；Shortcoming manufacturing process complexity efficiency bottom, influences motor performance and size to have deformation condition after welding.
In addition, the electric machine iron core stamping blanking and has buckleing a little for punching in mould, by between adjacent stamping
Button point snapping, folded riveting is together；Have the disadvantage the tense-lax that the stamping for the stator-rotor iron core that this mould production is obtained is stacked
Degree is poor, has gap between piece and piece, it is necessary to be completed with press secondary pressurized, iron core perpendicularity and flatness are poor, in aspect of performance
There is magnetic resistance influence, reduce motor performance.
In summary, the existing mould for making electric machine rotor iron core has the following disadvantages：
1st, punching press lamellar body is scattered on the ground, and manual sorting, is wasted time and energy, low production efficiency.
2nd, need artificial be superimposed multi-disc stamping to be placed in again on frock clamp, then weld, artificial superposition is easily caused
Adjacent stamping registration is low, influences motor performance and size to have deformation condition after welding.
3rd, the tense-lax degree that stamping is stacked is poor, has gap between piece and piece, it is necessary to be completed with press secondary pressurized, iron
Core perpendicularity and flatness are poor, have magnetic resistance influence in aspect of performance, reduce motor performance.

Embodiment
Shown in reference picture 1, Fig. 2, a kind of automatic viscose glue lamination high speed stamping progressive die of electric machine iron core, it include upper mould 8,
Lower mould 1, stock guide 2, the upper mould 8 include upper bolster 8.1, upper padding plate 8.2, convex mould pad 8.3 and blanking punch 8.4, described
Lower mould 1 includes blanking die 3, concave template 4, cavity plate backing plate 5, clamp ring 6, die shoe 7 from top to bottom, and blanking die 3 is arranged on
In concave template 4, clamp ring 6 is located at the lower section of blanking die 3, and clamp ring 6 is axially arranged with locking hole 6.1, it is ensured that between stamping 11
Perpendicularity and the depth of parallelism, blanking die 3 and locking hole 6.1 be relative, and the internal diameter of clamp ring 6 is less than the internal diameter of blanking die 3, clamp ring
6 framves are placed in die shoe 7, and the lower section of die shoe 7 is provided with products export 7.1, and the lower end of locking hole 6.1 is communicated with products export 7.1；It
Also include bonded assembly, described bonded assembly includes the automatic supplies 9.2 of glue case 9.1, glue, the flexible pipe being sequentially connected
9.3 and shower nozzle 9.4, described shower nozzle 9.4 is arranged in blanking punch 8.4, and the spout of shower nozzle 9.4 directly extends through blanking punch
8.4 stamping surface.Described glue case 9.1 is on the common chest for storing glue, the automatic direct market of supplies 9.2 of glue
The existing equipment that can be purchased.Described glue is the special rapid-curing cutback anaerobism glue of silicon strip.
The described lower section of stock guide 2 is provided with buoyant component, and buoyant component is arranged in blanking die 3, and buoyant component is located at
Offset below flitch 12 and with flitch 12.The importance of buoyant component design is the end face and flitch 12 for ensureing blanking punch 8.4
Can closely it contact, it is ensured that glue can be sprayed on flitch 12.
Described buoyant component includes spring 10.1 and buoyant pin 10.2, and blanking die 3 is provided with vertical blind hole, spring 10.1
It is located at buoyant pin 10.2 in blind hole, buoyant pin 10.2 is arranged on the upper end of spring 10.1, the upper end of buoyant pin 10.2 is as falling
Offset on the material end face of cavity plate 3 and with flitch 12.
The spout of described shower nozzle 9.4 more than three, it is arranged in a ring.
The present invention operation principle be：Described flitch comes from stock guide 2, is rushed by the blanking punch 8.4 on upper mould 8
Disconnected, in 8.4 punching press flitch of blanking punch, a certain amount of glue is sprayed on flitch by shower nozzle 9.4, and stamping 11 falls into blanking
In cavity plate 3, stamping 11 is fallen into clamp ring 6 with self gravitation, and the perpendicularity and the depth of parallelism between stamping 11 can be obtained
To guarantee；The internal diameter of clamp ring 6 is less than the internal diameter of blanking die 3, that is to say, that locking hole of the diameter of stamping 11 than clamp ring 6
6.1 is slightly larger, so stamping 11 will not drop under its own gravity, with increasing for stamping 11, the stamping of bottom
11 are moved downward under upper die punch effect, and drift is acted every time, and the stamping 11 of bottom can all move down a punching press
The stroke of the thickness of piece 11, and collect in clamp ring 6, without stamping 11 is superimposed into fixation, this hair with frock clamp again
The bright voluntarily collecting function for realizing stamping 11, can greatly reduce later stage cost of labor；Due to the upper surface of stamping 11
Provided with glue, therefore adjacent stamping can bond together, and receive the extruding of blanking punch 8.4, so what is be connected rushes
Gap very little between tabletting 11, registration is high；Period, if the quantity of stamping 11 reaches setting value, in stamping 11
Shower nozzle 9.4 stops a glue spraying water in action process, then just completes one group of stamping 11 and combines.
After the stamping 11 of bottom enters the scope that light channel 9 can be irradiated to, laser welding light emitters 8
Transmitting laser beam welds adjacent stamping 11, realizes automatic welding, improves operating efficiency.When required stamping 11
When superposition quantity reaches required thickness, laser welding light emitters 8 stop transmitting laser beam, that is midway stops one
Secondary transmitting laser beam, then the stamping 11 that two of which is connected will not be welded, so that part being welded exists
Drift works on down to come off from locking hole 6.1, is dropped out from the outlet 7.1 of die shoe 7.
A kind of automatic viscose glue lamination high speed stamping progressive die of electric machine iron core of the present invention, the lower section of blanking die 3 is provided with lock
Collar 6, it is ensured that iron core perpendicularity and flatness, adjacent stamping registration are high, clamp ring 6 is used to collect stamping, Ke Yi great
Big reduction later stage cost of labor.Bonded assembly is set on upper mould 8, the synchronous progress being bonded in punching press is realized, carries significantly
High workload efficiency.By the way of bonding, without folded riveting button point in stamping 11, iron core product surface is quite smooth, magnetic resistance shadow
Pin is rung, has one layer of rapid-curing cutback anaerobic adhesive to play certain insulation effect between each stamping 11, is conducive to improving the performance of motor.
