Embodiment：
Referring to accompanying drawing.
A kind of arrangements for automotive doors external door skin covering cold pressing composite die, the mould is mainly by punch-pin 1, cavity plate 2, punch-pin mould
Frame 3, cavity plate mould bases 4, the trimming flange edge of a knife 5, drift 6, punching set 7, punch-pin blank holder 8, cavity plate blank holder 9, guide pin bushing 12, discharging
Bar 13 is formed, and punch-pin 1 is provided with the punch-pin mould bases 3, is provided with outside the punch-pin 1 and is oriented to the punch-pin blank holder of cooperation with it
8, the cavity plate mould bases 4 fastened with it is installed on the punch-pin mould bases 3, the lower surface of the cavity plate mould bases 4 is provided with and punch-pin
The cavity plate blank holder 9 that blank holder 8 coordinates, cavity plate 2, the cavity plate 2 are installed on the cavity plate mould bases 4 in the cavity plate blank holder 9
Can in cavity plate blank holder 9 guiding movement, the drift 6 on the cavity plate 2 be fixed on cavity plate 2 with cavity plate blank holder 9, with institute
State punching set 7 corresponding to drift 6 to be embedded on punch-pin 1, trimming is turned over to fix all over the edge of a knife 5 and is embedded in cavity plate blank holder 9, described to unload
Material bar 13 is installed in punch-pin blank holder 8, and the punch-pin 1 is provided with the dumping pit coordinated with discharge arm 13.
Described punch-pin 1 is car door crust moulding surface structure, and its sheet material to be formed is positioned over punch-pin blank holder 8 and cavity plate flanging
Circle 9 between, the punch-pin mould bases 3 is installed on the table, the punch-pin blank holder 8 by its bottom hydraulic press jacking cylinder top
Rise, the clamping of cavity plate mould bases 4 is closed on the sliding block of hydraulic press by the opening of slider of hydraulic press and workbench, completes punching
It is molded.
Described cavity plate 2 is by guide pillar 11, guide rod 14 and the flexible fastening of spring 10 in cavity plate blank holder.
Several pilot holes are distributed with described cavity plate 2, guide rod 11, the guiding are installed in which part pilot hole
Spring 10 is set with bar 11, the guide pillar 11 with position-limiting action is also equipped with the pilot hole of part, and fix by guide pin bushing 12.
Such as Fig. 1：Punch-pin blank holder is raised above punch surface 30mm positions by the jacking cylinder top of hydraulic press, and lift-up pressure is adjusted
Most 10kpa, puts the sheet material of size needed for workpiece on punch-pin blank holder, and cavity plate is fixed on cavity plate blank holder by guide rod
It is interior, wherein equipped with multiple die springs, the cooperation of spring and guide rod, enable cavity plate up and down in cavity plate blank holder,
So as to the downward drawing of blank holder in drawing process, do not obstructed by cavity plate, cavity plate blank holder is fixed on cavity plate mould bases, and recessed
Then clamping is on the sliding block of hydraulic press for mould mould bases, when sliding block, which presses to cavity plate blank holder, to be bonded with punch-pin blank holder, it is meant that
Sheet material on punch-pin blank holder is compacted, and is continued to press to 20mm punch-pin under punch surface and is bonded with cavity plate, the spring on cavity plate
Start stress, continue to push 30mm, at this moment the sheet material clout of outer ring no longer will be shunk as type face, and the toughness of raw sheet material is removed,
So as to improve the plasticity and rigidity of whole car door external door skin.This nested structure completes required drawing process.
Such as Figure 15：In above-mentioned drawing process, when blank holder is pushed more than punch surface 40mm, this trimming structure comes into force,
Trimming is turned over to fix all over the edge of a knife and is embedded in cavity plate blank holder, and punch-pin casts using air-cooled steel with the trimming flange edge of a knife and processed,
By Quenching Treatment, knife edge surfaces hardness reaches 48HRC~55HRC, and gap, which coordinates to control in 0.05~0.08mm, this gap, is
/ 10th of sheet metal thickness, therefore after continuing to push more than convex model 40mm, the edge of a knife on punch-pin can be with trimming flange knife
Mouth coordinates, and unnecessary leftover pieces are cut off.This nested structure completes required trimming technology.
Such as Figure 16：After above-mentioned trimming process, when blank holder is pushed more than punch surface 41mm, this flange body comes into force,
The inner side of the trimming flange edge of a knife is exactly the flange edge of a knife, and therefore, the edge of a knife type face thickness of whole flange trimming is 9mm, type surface chamfer,
The flange edge of a knife mouth line of inner side will be less than the trimming edge of a knife in outside, so as to solve the sequencing problem of first trimming flange again, trimming
The interior side flanging edge of a knife fit clearance of interior the side flanging edge of a knife and punch-pin of the flange edge of a knife is 0.8mm~1mm, more than sheet metal thickness
0.1mm~0.2mm, the workpiece in turn-up process is neither ftractureed, in turn ensure that the door skin mouth line turned over time is clear, r angles are less than normal.Turn over
The side edge of a knife is pressed at the 50mm under punch surface with cavity plate blank holder always, that is to say, that the overall stroke of the flange edge of a knife is
9mm, so that the angle of flange is less than 95 °.This structure completes required flanging process
In above-mentioned turn-up process, at flange stroke to 8mm, this punch structure comes into force, and the drift on cavity plate is fixed on recessed
Mould is then embedded on punch-pin with the punching set in cavity plate blank holder, and needed for punching, and when workpiece stretches, the spring on cavity plate is not
Disconnected be pressurized is shunk, and total retraction stroke is 30mm, but the distance on the top of drift and cavity plate type face only has 29mm, then in spring
When retraction stroke is to 29mm, that is, when flange stroke is to 8mm, cavity plate type face, workpiece now will be exceeded by continuing to push drift
Basic drawing and forming, moulding to be reached target effect with rigidity, the sheet material around punching has all compressed, and drift coordinates with punching
Hole needed on car door crust is punched into, completes punching technology
Such as Figure 17：After the completion of above-mentioned all techniques (process), car door door skin, which is already molded, to be tightened, so in pickup,
Need a discharging structure.This structure is that 7 discharging push rods are installed in punch-pin blank holder, after all process steps are completed,
Press jacking cylinder resets, and punch-pin blank holder is jacked to 30mm on punch surface, so that discharging push rod passes through punch-pin
Dumping pit is ejected, and the car door crust after shaping is ejected from punch-pin.The present invention solves can not be by all works in prior art
The problem of ordered sets is on a secondary mould.And can not the punching press completion on a secondary mould by a car door external door skin.
Solution and principle：Using the stretching travel needed for drawing process, by each step process of shaping, and cut
Side, flange, punching being merged into by cleverly structure in whole set of die without any confusion.
