The gap of blank holder 15 and punch-pin 14 in the horizontal direction constitutes the region outer ring Fen Mo, upper die holder 5 and skylight pressure plate 3
Gap in the horizontal direction constitutes inner ring and divides mould region.
Include five steps when the top cover inner plate stamping die works:
Step 1: blank holder 15 receives cushion thrust lifting theory stroke under press, top cover inner plate plate is launched to pressure
On 15 type face of flange, and its play in face is controlled by tablet locator 6；
Step 2: delivering a signal to press by the tablet locator 6 that plate triggers, press drives upper mold assembly from top dead-centre
Component downlink drives the downlink together of blank holder 15,15 drawing of 5 drawbead rib of upper die holder and blank holder after touching blank holder 15
Muscle groove collective effect completes locking tablet, realizes mould assembling action, and plate starts to be plastically deformed；
Step 3: 16 sword of deburring cutter block enters, upper die holder cuts corner area material, punch-pin 14 starts to form in partial roof cover
Plate part feature, skylight pressure plate 3 contact plate after with punch-pin 14 accomplish by joint efforts the compression to skylight inside plate, and and upper mold
Assembling assembly downlink together；
Step 4: 10 pier of blank holder limited block is died of on 12 characteristic face of lower die holder, upper and lower mould when press motion is to bottom dead centre
Type face is bonded completely, and forming parts terminate；
Step 5: upper mold assembly group uplink, air cushion pushes 15 uplink of blank holder, forming part and upper mold and punch-pin under press
14 are detached from, and upper mold assembling assembly returns to initial position.
The outer ring region the Fen Mo about 5-8mm that blank holder 15 and punch-pin 14 are constituted in the horizontal direction, upper die holder 5 and skylight binder
The inner ring that plate 3 is constituted in the horizontal direction divides mould region about 3-5mm.
Bead cross-sectional shape is unrestricted (including circular cross-section, rectangular section, odd-shaped cross section), and Same Part is different
Regional cross section shape and depth can be distributed according to part feature differentiation；Bead profile is unrestricted (including closed, open
Formula), bead quantity (1,2) can suitably be chosen according to part feature.
With the contact in slide guide face prior to 3 guide plate of skylight pressure plate and slide guide face contact, preferred value is upper die holder guide plate 9
50mm。
The present invention can effectively solve the problem that the Plastic Flow consistency of top cover inner plate skylight region material is poor, top cover inner and outer plates packet
The problems such as rigidity that side face plastic deformation is insufficient is weak and the rebound of part type face is overproof serious, shortens part debugging cycle, realizes top cover
Inner panel punched becomes second nature regulation, improves top cover inner plate Forming Quality.Top cover inner plate stamping die forms initial stage corner area material
Material is edged cutter block and crops, and inside and outside circle divides mould region to make adhesive force between upper and lower model face controllable, so that skylight region
Feature forming process is controllable, is effectively improved the consistency of skylight region material Plastic Flow, enhances the bound edge dough model of top cover inner and outer plates
Property deformation extent, the rebound of effective control type face is overproof, is conducive in solving the influence vehicles such as top cover assembly rigidity deficiency, dimension overproof
The quality problems of body function realize that stamping top cover becomes second nature control.
Specific examples are applied in the present invention, and principle and implementation of the present invention are described, above embodiments
Illustrate to be merely used to help understand method and its core concept of the invention；At the same time, for those skilled in the art, according to
According to thought of the invention, there will be changes in the specific implementation manner and application range.In conclusion the content of the present specification
It should not be construed as limiting the invention.
