Description
Technical field
The utility model relates to a kind of mould structures for punching machine punching.
Background technique
It is well known that the progressive die has the advantages that accurate, efficient, province people, but the step pitch of feeding must be consistent.So for
In the case that part step pitch is long, will lead to mold and the lathe to match can also be increased, but step pitch simple for some structures
Too long part, if produced with the lathe of large-tonnage clearly non-remunerative.Such as a width 58.5mm length
The part of 1400mm, it is 4.2mm, the hole of 1.8 mm of diameter that centre, which rushes 283 spacing,.The prior art sets such part progressive die
Only there are two types of feeding styles for meter:
1. lateral feeding, step pitch about 62 ~ 63mm influences appearance the disadvantage is that connect the edge of a knife for mold.And stock utilization
Low, manufacturing cost is too high.
2. longitudinal feeding, step pitch about 1402mm. continuous die design need 2 work steps.So die length is up to 3200mm
More than, lathe platen length needs 3500mm or more, and small processing factory does not have the lathe of this large-tonnage, large-scale processing factory generally
With machine and low load with strong power, to cause to waste.
Summary of the invention

It is fixedly connected；The skewback 236 is located in the horizontal sliding space A of the skewback, 236 energy of skewback under the drive of the cylinder 235
The horizontal sliding in the horizontal sliding space A of the skewback；It is equipped with lower inclined plane 236A in 236 front lower portion of skewback, in the punching
The outer end top of head fixed plate 238 and cover board 239 is equipped with the ramp 241 that can be interacted with lower inclined plane 236A, described oblique
Block 236 makes 238 and of punch fixing plate under the promotion of the cylinder 235, through the interaction of ramp 241, lower inclined plane 236A
The glide downwards after overcoming 240 elastic force of fixed plate return spring of cover board 239, the bottom of formed punch guide plate 233 is exposed in 237 lower end of formed punch at this time
Face, as shown in figure 3, next, upper die holder 231 moves down, piercing die group (can be first or two piercing die group)
Work is punched out to the plate being advanced between formed punch guide plate 233 and stripper 234, wherein the first piercing die group is mainly
For rushing location hole, used when being positioned to subsequent correcting positioning module 4；Second piercing die group is mainly to rush the workpiece of metal plate part
Hole；
The quantity of correcting positioning module 4 is changed to be now divided into the process for completing original one-off hole-piercing repeatedly change step
The number completed away from punching is corresponding, as shown in Figure 5,6, all correcting positioning modules 4 include positioning mould holder 41, backing plate 42,
Positioning guide plate 43, cylinder 44, positioning skewback 45, correcting head 46, correcting head fixed plate 47, cover board 48 and fixed plate return spring 49,
The backing plate 42 is mounted between positioning mould holder 41 and positioning guide plate 43 and they is separated to form the horizontal sliding space B of skewback；
The correcting head 46 is sequentially loaded into correcting head fixed plate 47 and positioning guide plate 43, and by covering in correcting head fixed plate 47
Cover board 48 covers tightly fixation；The fixed plate return spring 49 withstands on the correcting head after being located in the groove of 43 upper surface of positioning guide plate solid
On the bottom surface of fixed board 47 so that correcting head fixed plate 47 and cover board 48 along the side wall of the backing plate 42 up reset after make the correcting head
46 are retracted into positioning guide plate 43；The cylinder 44 is fixed on the side of positioning mould holder 41, cylinder rod and positioning skewback 45
It is fixedly connected；The positioning skewback 45 is located in the horizontal sliding space B of the skewback, the positioning skewback under the drive of the cylinder 44
45 can pass in and out the horizontal sliding space B of the skewback；It is equipped with lower inclined plane 45A in 45 front lower portion of positioning skewback, in the correcting
The outer end top of head fixed plate 47 and cover board 48 is equipped with the ramp 50 that can be interacted with lower inclined plane 45A, the locating latch
Block 45 makes correcting head fixed plate 47 and cover board under the promotion of the cylinder 44, through the interaction of ramp 50, lower inclined plane 45A
48 expose bottom surface and the insertion of positioning guide plate 43 after overcoming 49 elastic force of fixed plate return spring to enforcement 46 lower end of correcting head that glides
Into the location hole of plate, following first piercing die group 2 or two piercing die groups 3 can be carried out punch work.
It is the schematic diagram that point three step punchings are a circulation shown in Fig. 7, work step is following, and (feeding mechanism of punching machine is
The stroke of common structure, each step is set by control system, is omitted herein):
The first step is as origin: the first piercing die group 2, the work of the second piercing die group 3, goes out location hole D, laterally densely covered
Workpiece hole E1；
Step 2: first time feeding, after stroke L1, leftmost that correcting positioning module work, at this moment its correcting head
46 are inserted into the made location hole D of previous step, and after plate is had good positioning, next part is gone out in the work of the second piercing die group 3
Workpiece hole E2；
Step 3: second of feeding, after stroke L2, intermediate that correcting positioning module work, at this moment its correcting head 46
It is inserted into the made location hole D of the first step, after plate is had good positioning, next part is gone out in the work of the second piercing die group 3
Workpiece hole E3；
Step 4: third time feeding, after stroke L3, that correcting positioning module of rightmost works, and plate is had good positioning
Afterwards, the first piercing die group 2, the work of the second piercing die group 3, the workpiece hole going out location hole D, laterally gathering；
It is next, repeat first to fourth step, this to be completed three times by becoming step pitch, continuous workpiece is gone out with this
Hole.
It is this originally once rushing from the aforegoing it can be seen that the utility model goes out continuous hole by repeatedly becoming step pitch
The process that hole is completed, which is changed to be now divided into, repeatedly becomes the structure that step pitch punching is completed, compared with the machine that longitudinal feeding needs large-tonnage
For the continuous punching of bed ability, its use cost is lower, and the mold generated when rushing continuous aperture compared with lateral feeding connects knife
Mouth mostly and unsightly for, the hole that it is rushed out more meets the requirements, thus the more reasonable structure of the utility model and use at
This is lower, and the continuous aperture quality gone out is more stable, reliable.
Although the utility model is described in detail referring to above example, by the disclosure for those skilled in the art
Member is not it is readily apparent that and the case where departing from the principles of the present invention and scope that the claim limits
Under, the utility model can be made a variety of changes or be modified.Therefore, the detailed description of the embodiment of the present disclosure is only used to explain, and
It is not intended to limit the utility model, but is defined by the subject-matter of the claims the range of protection.
