Background technology
In recent years, the continuous breakthrough of new material research and development, various thin material plastics on new materials pass through thermoforming technology, can reach very high
Intensity, be sufficient for the very thick material of previous automobile, the intensity requirement that can be only achieved.With these new diseases,
Automobile own wt substantially mitigates, and realizes vehicle weight lightweight, and then realize energy-saving.To adapt to this trend, very much
The support elements such as automobile A, B, C column are all using thermoforming technology.Therefore for support elements such as these A, B, C columns, these to be developed
The grading blanking die of product, since these product volumes are big, to improve stock utilization, saving the considerations such as earth resource, we
Can generally select that production efficiency is higher, stock utilization is higher when stock layout one goes out two, one and goes out the pattern types such as more,
Therefore these grading blanking dies generally all can be very big, and punch is more, and in production, this may result in blanking pressure and noise is especially big,
It is easy to cause the life injury to producers.
Utility model content
The applicant is directed to disadvantage mentioned above, has carried out Improvement, provides a kind of grading blanking of damping noise reduction large size punching press
Mold.
Technical solution is as follows used by the utility model：
A kind of grading blanking die of damping noise reduction large size punching press, including upper mold seat and die holder, connects under the upper mold seat
Upper padding plate, the upper padding plate lower section are fixed the upper clamp plate with the different trimming punch of several height, are covered on the trimming punch
If stripper plate, the stripper plate connects upper mold seat, the de- material by the high screw such as upper mold, upper mold nitrogen gas spring and upper mold guide post
Plate lower end connects window board, and the window board lower end connection guides needle, connects lower bolster on the die holder, coordinate on lower bolster
The trimming punch of upper mold seat connects several lower die edges of a knife, is arranged material lift plate on the lower die edge of a knife, the material lift plate passes through lower die
Contour screw, lower die nitrogen gas spring and lower die guide post connect die holder, connect stock guide on the material lift plate, on the upper mold seat
Outer guiding post is also connected with, outer bush is connected on the die holder of cooperation.
As a further improvement of the above technical scheme：
The trimming punch lower end sets centroclinal punching inclined-plane, and the punching inclined plane shape of different trimming punches
It is different.
The beneficial effects of the utility model are as follows：The trimming punch of the grading blanking die of damping noise reduction large size punching press
Height is different, and shape is different, makes trimming punch with being contacted during tablet difference, it is possible to reduce the face that punch contacts simultaneously with tablet
Product effectively reduces blanking pressure, punching noise and vibrations during punching, reduces the personal injury of noise and vibrations to Manufacturing Worker.

Specific embodiment
Below in conjunction with the accompanying drawings, illustrate specific embodiment of the present utility model.
As shown in Figure 1 to Figure 3, the grading blanking die of damping noise reduction large size punching press of the present embodiment, including upper mold seat 1 under
Die holder 2,1 time connection upper padding plate 11 of upper mold seat, 11 lower section of upper padding plate is fixed to carry the upper of the different trimming punch 12 of several height
Clamping plate 13, the centroclinal punching inclined-plane 121 of 12 lower end of trimming punch setting, and the punching inclined-plane of different trimming punches 12
121 shapes are different, and stripper plate 14 is arranged on trimming punch 12, and stripper plate 14 passes through the high screw 15 such as upper mold, upper mold nitrogen bullet
Spring 16 and upper mold guide post 17 connect upper mold seat 1,14 lower end of stripper plate connection window board 18,18 lower end of window board connection guiding needle
19, connect lower bolster 21 on die holder 2, the trimming punch 12 of cooperation upper mold seat 1 connects several lower die edges of a knife 22 on lower bolster 21,
Material lift plate 23 is arranged on the lower die edge of a knife 22, material lift plate 23 passes through the high screw 24 such as lower die, lower die nitrogen gas spring 25 and lower die guide post
26 connect die holders 2, and stock guide 27 is connected on material lift plate 23, outer guiding post 3 is also connected on upper mold seat 1, connects on the die holder 2 of cooperation
Connect outer bush 4.
The grading blanking die of damping noise reduction large size punching press is in use, the upper mold seat 1 is connected on punching machine, die holder
2 are connected on the work top below punching machine, and material strip is located in by stock guide 27 on material lift plate 23, and punching machine drives upper mold seat 1
Decline, guiding needle 19 is first contacted with material strip, positioning is fixed on material lift plate 23, window board 18 presss from both sides material strip with material lift plate 23
Tightly, since 16 power of upper mold nitrogen gas spring is much larger than 25 power of lower die nitrogen gas spring, punching machine drives upper mold seat 1 to continue traveling downwardly, material lift plate
23 decline therewith, and until 25 stroke of lower die nitrogen gas spring is covered, after 25 stroke of lower die nitrogen gas spring is covered, punching machine drives
Upper mold seat 1 continues traveling downwardly, and stripper plate 14 is located proximate to respect to upper mold seat 1, until upper mold nitrogen gas spring 16 covers a stroke, cuts
