203 and second lower die floating block 207 by material 2 201 compress after, the second stamping die 2 is enabled to proceed to and is closed completely（Such as Fig. 4
It is shown）, first time drawing is completed, during the second stamping die 2 is opened, the second lower die floating block 207 is in the second lower die bullet
Under the action of spring 208, product break away from moulds is completed, obtains the material 3 301 after first time drawing；
Step 3：Material 3 301 is placed in third stamping die 3（As shown in Figure 5）, third stamping die 3 is enabled to start to close
It closes, after taking off in third molding punching pin 303 and being contacted with material 3 301（As shown in Figure 6）, third stamping die 3 is enabled to continue to be closed,
After material 3 301 is contacted with third lower die floating block 311（As shown in Figure 7）, third stamping die 3 is enabled to continue to be closed, due to
The power of three lower die springs 312 is less than the power of third upper mold spring 307, and third lower die floating block 311 can move downward（Such as Fig. 8 institutes
Show）, the first time deep-drawn parts inside material 3 301 are compressed at this time, third stamping die 3 is enabled to continue to be closed, treats that third takes off
Plate enters son 302 and completes 3 301 outer perimeter section binder of material with third lower die forming part 308（As shown in Figure 9）Afterwards, third is enabled to rush
Compression mould 3, which proceeds to, to be closed completely（As shown in Figure 10）, second of drawing is completed, in the mistake that third stamping die 3 is opened
Cheng Zhong, third lower die floating block 311 complete product break away from moulds under the action of third lower die spring 312, open third stamping die
Tool 3 obtains the material 4 401 after second of drawing；
Step 4：Material 4 401 is placed in the 4th stamping die 4（As shown in figure 11）, enable the 4th stamping die 4 run to
It is closed completely（As shown in figure 12）, material shaping is completed, opens the 4th stamping die 4, obtains the material 5 501 after integer；
Step 5：Material 5 501 is placed in the 5th stamping die 5（As shown in figure 13）, enable the 5th stamping die 5 run to
It is closed completely（As shown in figure 14）, then the 5th stamping die 5 is opened, obtain the material 6 601 after endoporus blanking；
Step 6：Material 6 601 is placed in the 6th stamping die 6（As shown in figure 15）, the 6th stamping die 6 is enabled to start to close
It closes, after the 6th de- plate part 602 is contacted with material 6 601, the 6th stamping die 6 is enabled to continue to be closed, due to pushing up bullet in punching pin
The power of spring 606 is more than the power of the 6th lower die spring 611, and taking off part 610 in the 6th lower die moves downward（As shown in figure 16）, enable
Six stamping dies 6 continue to be closed, and the 6th de- plate part 602 is closed with the 6th lower die part 607 at this time, then 6 601 binder of material
It completes（As shown in figure 17）, the 6th stamping die 6 is enabled to proceed to and is closed completely（As shown in figure 18）, flange punching pin at this time
603 complete flange, in 6 opening procedure of the 6th stamping die, since the power that spring 606 is pushed up in punching pin is more than the 6th lower die spring
611 power, ejector pin 605 leaves in punching pin take off part 610 in the 6th lower die after, part 610 is taken off in the 6th lower die and has been moved upwards
Into flange de- material, the 6th stamping die 6 is opened, obtains the material 7 701 after inside port blockage；
Step 7：Material 7 701 is placed in the 7th stamping die 7（As shown in figure 19）, the 7th stamping die 7 is enabled to start to close
It closes, the 7th de- plate part 703 first touches the 7th lower die buoyant part 707（As shown in figure 20）, with the 7th stamping die 7
It is closed, the 7th lower die buoyant part 707 is pushed, material 7 701 completes material seven when touching the seven times molding compound parts 709
701 positioning simultaneously compress material 7 701（As shown in figure 21）, the 7th stamping die 7 is enabled to continue to be closed, the 7th de- plate punching pin 702
7 701 surrounding blank of material is completed with the lower die edge of a knife 704（As shown in figure 22）, open the 7th stamping die 7（As shown in figure 23）,
Obtain the product after surrounding blank.
Preferred embodiment is：In step 7, it is additionally included in after opening the 7th stamping die 7, passes through blowing method
