Description
Technical field
The present invention relates to a kind of stamping devices and method for the processing of automobile panel inner panel.
Background technique
When automobile panel inner panel punch process, the depth of drawing die face is larger, and plate consumption of raw materials is larger.Existing punching press
Device is single draw mode structure, can not effectively solve the problems, such as that material is largely lost.
Summary of the invention
Goal of the invention of the invention is to provide a kind of stamping device and method for the processing of automobile panel inner panel, energy
It is enough effectively to solve the problems, such as that material is largely lost, material loss is effectively reduced.
Based on the same inventive concept, there are two independent technical solutions for present invention tool:
1, a kind of stamping device for the processing of automobile panel inner panel, drawing die includes upper die and lower die, and feature exists
In: it is additionally provided with upper blank holder and lower blank holder, upper mold, upper blank holder, lower blank holder, lower die are from top to bottom set gradually.
Upper blank holder and lower blank holder can move up and down；Upper blank holder and lower blank holder can be closed to form binding face, right
Plate is clamped.
The edge of lower blank holder is equipped with the recessed low profile that matches with upper mold, the edge of upper blank holder be equipped with it is aforementioned
The opening that recessed low profile matches.
Type face on upper blank holder is respectively positioned on the large curved surface of blank holder；Type face on lower blank holder is respectively positioned on pushing
Under the large curved surface of flange.
2, a kind of process for stamping using the above-mentioned stamping device for the processing of automobile panel inner panel, it is characterised in that:
Lower blank holder is risen, rises upper mold to limit level, blank holder in rise；
Plate is placed on lower blank holder, upper blank holder downlink forms fitting until upper blank holder and lower blank holder are closed
Face clamps plate；
Upper mold downlink, the recessed low profile on upper mold and lower blank holder edge act on, to plate carry out recessed low profile at
Type；
Upper mold continues traveling downwardly, and upper mold and upper blank holder, lower blank holder integrator and lower die act on, and completes plate forming.
Plate is limited by positioning pin, is placed on lower blank holder.
The minimum point of sheet forming is lower than the binding face between upper blank holder and lower blank holder.
The highest point of sheet forming is higher than binding face 153mm between upper blank holder and lower blank holder, sheet forming it is minimum
Point is lower than binding face 25mm between upper blank holder and lower blank holder.
The invention has the benefit that
The present invention optimizes existing single-action drawing die, adds double blank holders, upper mold, upper flanging are successively arranged under
Circle, lower blank holder, lower die when punching press, rise lower blank holder, rise upper mold to limit level, blank holder in rise；Plate is put
It sets on lower blank holder, upper blank holder downlink, until upper blank holder and lower blank holder are closed, form binding face, plate is pressed from both sides
It holds；Recessed low profile on upper mold downlink, upper mold and lower blank holder edge acts on, and carries out recessed low profile molding to plate；On
Mould continues traveling downwardly, and upper mold and upper blank holder, lower blank holder integrator and lower die act on, and completes plate forming.The present invention is first led to
It crosses down blank holder to form the recessed low profile of two sides above and below plate, i.e., segmentation is optimized to the die face of two sides above and below plate,
So that the whole design depth of drawing die face substantially reduces, under the premise of guaranteeing processing quality, material loss is effectively reduced.This
Type face in invention on blank holder is respectively positioned on the large curved surface of blank holder；Type face on lower blank holder is respectively positioned on lower blank holder
Large curved surface under, can guarantee to be bonded effect between upper blank holder and lower blank holder, to plate realize reliable retention.This hair
Isotropic disk material is limited by positioning pin, is placed on lower blank holder, and positioning of the plate on lower blank holder is further facilitated.This
The minimum point of invention sheet forming is lower than binding face 25mm between upper blank holder and lower blank holder, compared with existing drawing, depth
It reduces and reaches 45mm, further increase and save material consumption effect.
Detailed description of the invention
Fig. 1 is overall structure of the present invention；
Fig. 2 is the top view of upper mold of the present invention；
Fig. 3 is the top view of the upper blank holder of the present invention；
Fig. 4 is the top view of the lower blank holder of the present invention；
Fig. 5 is the top view of lower die of the present invention.
Specific embodiment
As shown in Figure 1, drawing die includes upper mold 1, upper blank holder 2, lower blank holder 3, lower die 4, upper mold 1, upper blank holder 2,
Lower blank holder 3, lower die 4 are from top to bottom set gradually.Upper blank holder 2 and lower blank holder 3 can move up and down；Upper 2 He of blank holder
Lower blank holder 3 can be closed to form binding face, clamp to plate.As shown in Fig. 2, upper mold is equipped with the first recessed low profile 5, the
The recessed low profile 7 of two recessed low profiles 6, third, the 4th recessed low profile 8, as shown in figure 4, the edge of lower blank holder is equipped with
The recessed low profile 9 of first matched with upper mold, the second recessed low profile 10, the recessed low profile the 11, the 4th of third are recessed small-sized
Face 12, as shown in figure 3, the edge of upper blank holder is equipped with the opening matched with aforementioned recessed low profile.Described upper mold 1 and upper pressure
Flange 2 is needed flexibly rationally to be divided by cylinder location, structural strength and closure, and the type face on upper blank holder is respectively positioned on
On the large curved surface of blank holder, described lower blank holder 3 and lower die 4 are needed flexibly to carry out by mandril position, structural strength and closure
Rationally divide, the type face on lower blank holder is respectively positioned under the large curved surface of lower blank holder.
When punch process, lower blank holder 3 is risen, rises upper mold 1 to limit level, blank holder 2 in rise places plate
On lower blank holder 3, plate is limited by positioning pin；Under cylinder promotion, upper 2 downlink of blank holder, until upper blank holder 2 with
Lower blank holder 3 is closed, and is formed binding face, is clamped to plate；Under on 1 downlink of upper mold, upper mold 1 and lower 3 edge of blank holder
Recessed low profile effect, carries out recessed low profile molding to plate；Then upper mold 1 continues traveling downwardly, and upper mold 1 and upper blank holder 2 push
3 integrator of flange and lower die 4 act on, and complete plate forming.The highest point of sheet forming in related example involved in the present invention
Higher than binding face 153mm between upper blank holder 2 and lower blank holder 3, the minimum point of sheet forming is lower than upper blank holder 2 and lower flanging
Binding face 25mm between circle 3.
