138 be internally provided with it is corresponding with above-mentioned bulge-structure position, in the compatible forming of structure take off punch 382, product is set in
Third shapes on lower punch 238, and when third forming upper cavity die 138 pushes, third shapes lower punch 238 and drives product insertion the
In three forming upper cavity dies 138, packet is drawn to product squeeze, shape in de- punch 382 at the drawing packet to product into
It goes back and pedals, obtain drawing pack arrangement.Built-in motor bearing in drawing pack arrangement at the top of product, dimensionally stable is formed by above-mentioned operation
Elongated structure come improve product processing precision so that the size for drawing packet is more matched with the size of motor bearing so that
When motor operation, preferably fixing bearing prevents bearing swash.The side to fit with product on third finishing die upper cavity die 138
Edge is equipped with the angles R shaping area 801, and forming stripper plate 383 is arranged on third forming lower punch 238, and product is set in third forming
On lower punch 238, and it is placed between the angles R shaping area 801 and forming stripper plate 383, when third forming upper cavity die 138 pushes,
Forming stripper plate 383 is driven to drop to dead-centre position, the bottom of product carries out the angles R in the angles R formation zone 801 and shrinks forming, with shape
At the angles R flex area.
First finishing die, the second finishing die are similar to the structure of third finishing die, include that bulge-structure is shaped with the angles R
Area, and along the direction of processing technology, the diameter of bulge-structure tapers into, height becomes larger, at the top of product
Form the tapered gradually high fixed drawing pack arrangement of size；The contact angle of the angles R formation zone is gradually sharp simultaneously, to product bottom
Portion carries out the angles R and shrinks forming.First finishing die, the second finishing die are similar to the effect of third finishing die, are no longer described in detail.
Please refer to Fig. 4-1, sizing die include shaping upper cavity die 139 and corresponding setting, structure it is compatible whole
Shape lower punch 239, shaping upper cavity die 139 are arranged with outside to the upper clamp plate 395 of fixed shaping upper cavity die 139, shaping lower punch
239 tops are equipped with convex block 391, and convex block 391 is equipped with through-hole 393, and 139 bottom of shaping upper cavity die is equipped with and 393 position phase of through-hole
Punch 392 is taken off in corresponding, the compatible shaping of structure, product is set on shaping lower punch 239, when shaping upper cavity die 139
