Movement travel in the horizontal direction.
Compared with prior art, the beneficial effects of the present invention are:
Using multi-angle diplopore punch die provided by the invention, for the multi-panel hole part with angle, which can one
Secondary property completes porous processing, reduces punching operation, reduces the exploitation tricks of mold, produces save the cost for enterprise.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of punch die；
Fig. 2 to Fig. 5 is path schematic diagram when punch die works；
Fig. 6 is the structural schematic diagram of punching part after molding.
Specific embodiment
The invention will be further described with attached drawing with reference to embodiments.
As shown in Fig. 1,4 and 6, part 20 needs the punching on two faces with angle, and it is more that the present invention provides one kind
Angle diplopore punch die, structure include upper die holder 1 and lower die holder 2, and wherein lower die holder 2 is equipped with punch-pin 3, and can be towards convex
The first tapered wedges 4 that mould 3 slides；Upper die holder 1 is equipped with the eccentric swage 7 of 3 face of punch-pin, for driving the first tapered wedges 4 to exist
The upper mold slotting tool 6 slided on lower die holder 2, and the second tapered wedges 8 between eccentric swage 7 and upper mold slotting tool 6, this second tiltedly
Voussoir 8 and the first tapered wedges 4 are respectively equipped with the second inclined surface 8a and the first inclined surface 4a in the two position facing each other, upper
During die holder 1 moves down, the first inclined surface 4a can with the second inclined surface 8a sliding contact, and push the second tapered wedges 8 exist
It is slided on upper die holder 1；Punch-pin 3 is equipped with the first supporting surface 3a and the second supporting surface 3b with angle, pacifies on the first tapered wedges 4
Equipped with the first formed punch 5 extended towards the first supporting surface 3a, it is equipped on the second tapered wedges 8 towards the second supporting surface 3b extension
Second formed punch 9.
For another example shown in Fig. 2 to 5, at work, upper die holder 1 moves down mold, and the promotion of upper mold slotting tool 6 first thereon is tiltedly
The Slideslip to the right on lower die holder 2 of voussoir 4, the first formed punch 5 on the first tapered wedges 4 can be to the plate part 20 on punch-pin 3
Carry out the punching processing in first hole；The second inclined surface after upper die holder 1 moves down certain stroke, on the second tapered wedges 8
Then the first inclined surface 4a sliding contact on 8a and the first tapered wedges 4 is oriented to by the mutual inclined-plane in two inclined-planes and is made
With the second tapered wedges 8 can slide to the right on upper die holder 1, i.e. the second formed punch 9 is mobile towards part 20, thus complete pair of panel
The punching processing in another hole on shape part 20.So the punch die can be disposable for the multi-panel hole part 20 with angle
Complete porous processing.
As shown in Figure 1, for convenient for mold complete punching after, the first tapered wedges 4, the second tapered wedges 8 and eccentric swage 7
It can automatically reset, the first reset nitrogen cylinder 11, two tapered wedges 8 and eccentric swage are installed between the first tapered wedges 4 and punch-pin 3
It is equipped with second between 7 and resets nitrogen cylinder 13, eccentric swage 7 is mounted on upper die holder 1 by nitrogen gas spring 12, and nitrogen gas spring 12
Formation with second reset nitrogen cylinder 13 flexible stroke it is orthogonal, can be avoided each component in reseting procedure and transport
Dynamic interference, guarantees the stability of mold movement.
Again as shown in Figure 1, the motion path of the first formed punch 5 is arranged in the horizontal direction, the motion path of the second formed punch 9 and
Two inclined surface 8a are parallel, and the first tapered wedges 4 are also to slide in the horizontal direction in mold work, can guarantee mold in this way
First passing through the first tapered wedges 4 at work drives the first formed punch 5 to process first hole in a manner of horizontal punching, then to incline
The mode tiltedly moved rushes second sky, is all to be punched out using inclined mode compared to two previous holes, has better
Machining accuracy, punching defect is less, and can satisfy the process requirements of specific component.
To control the movement travel in the horizontal direction of the first tapered wedges 4, lower die holder 2 is equipped in the side far from punch-pin 3
First limited block 10, the sliding stroke of the first tapered wedges 4 is between punch-pin 3 and the first limited block 10；To control the second inclined wedge
The movement travel in the horizontal direction of block 8, upper die holder 1 are fixedly installed with the second limited block 14 in corresponding 6 inner side of upper mold slotting tool,
The sliding stroke of second tapered wedges 8 is between eccentric swage 7 and the second limited block 14.
Again as shown in Fig. 2, the lower end of upper mold slotting tool 6 is equipped with inclined first guide surface 6a, the first tapered wedges 4 are corresponding the
One position guide surface 6a is equipped with the second guide surface 4b being adapted with the first guide surface 6a, when upper mold slotting tool 6 moves downward, leads to
The transmitting of power can be realized in the guiding cooperation for crossing the two inclined guide surfaces, so that the first tapered wedges 4 be pushed to move horizontally.
Finally, it should be noted that foregoing description is only the preferred embodiment of the present invention, the ordinary skill people of this field
Member under the inspiration of the present invention, without prejudice to the purpose of the present invention and the claims, can make multiple similar tables
Show, such transformation is fallen within the scope of protection of the present invention.
