Description
Technical field
The present invention relates to mould structure technology, more particularly, to one kind repair stamping die.
Background technology
For punching press parts, generally require and trimming and pruning are carried out to different parts, just can ultimately form our needs
Product.To scrap region, mainly there are two states in simple terms, outside trimming A and internal trimming B, as shown in Figure 1.
For internal trimming it is assumed that the trimming type face of part 1 and horizontal direction angle are α, when 0 °≤α≤20 °, typically
Trimming can be carried out by the way of just repairing, that is, go up mould cutter block 2 and carry out repairing punching to part 1 straight down, as shown in Figure 2.But, when
α>When 20 °, according to the mode just repaiied, then occur that part burr is big and mold notch intensity fragility phenomenon, not only can not expire
Sufficient part quality requires, and the mold notch life-span is extremely short.
Content of the invention
It is an object of the invention to provide one kind repaiies stamping die, to solve the problems of the prior art, it is to avoid part occurs big
The phenomenon of burr, improves the life-span of mold notch.
The invention provides one kind repaiies stamping die, wherein, including：

Lower die cutter block, is fixed on described lower mould；
Upper mould；
Pulley mechanism, including coaster body and coaster cutter block, described coaster body is fixed on described upper mould, described coaster
Cutter block is fixed on described coaster body, and described coaster body is provided with the second guiding surface；
Described first guiding surface and described second guiding surface cooperation, thus driving described coaster body motion, described
Coaster cutter block carries out trimming with described lower die cutter block cooperation to part.
Repair stamping die as above, these, it is preferred to, described coaster body is provided with gripper shoe, described coaster
Body is hung by described gripper shoe and is fixed on described upper mould.
Repair stamping die as above, these, it is preferred to, described coaster body is additionally provided with bottom surface guide plate and side
Guide plate, described bottom surface guide plate and side guide are slidably matched with described upper mould.
Repair stamping die as above, these, it is preferred to, described coaster body is provided with breaker bolt, described peace
Full bolt is spacing with the via cooperation on described upper mould.
Repair stamping die as above, these, it is preferred to, also include sleeve, be set on described breaker bolt, described
Step is provided with sleeve, described step is stuck in the via on described upper mould.
Repair stamping die as above, these, it is preferred to, the quantity of described breaker bolt and described sleeve is all two
Individual.
What the present invention provided repaiies stamping die by arranging the first guiding surface on lower mould, arranges second on coaster body
Guiding surface, the first guiding surface drives pulley mechanism oblique along the normal direction in trimming type face with the second guiding surface cooperation
Lower motion, until coaster cutter block is contacted, completes the trimming work of part with lower die cutter block.What the present invention provided repaiies stamping die in pin
In the case of 20 ° are more than with horizontal direction angle to part trimming type face, reduce the burr of part, improve mold notch
Life-span.

Specific embodiment
Embodiments of the invention are described below in detail, the example of described embodiment is shown in the drawings, wherein from start to finish
The element that same or similar label represents same or similar element or has same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
Fig. 3 is the structural representation repairing stamping die provided in an embodiment of the present invention, and Fig. 4 is the cooperation of pulley mechanism and lower mould
Schematic diagram, Fig. 5 is the structural representation of pulley mechanism.
As shown in Figures 3 to 5, embodiments provide one kind and repair stamping die, including lower mould 3, lower die cutter block 4, on
Mould 5 and pulley mechanism 6.Wherein, lower mould 3 is provided with the first guiding surface, lower die cutter block 4 is fixed on lower mould 3.Pulley mechanism
6 include coaster body 61 and coaster cutter block 62, and coaster body 61 is fixed on mould 5, and coaster cutter block 62 is fixed on coaster body
On 61.Second guiding surface 611 is provided with coaster body 61, the wherein first guiding surface and the second guiding surface 611 coordinate,
Thus driving coaster body 61 to move, coaster cutter block 62 and lower die cutter block 4 coordinate and carry out trimming to part.
During work, upper mould 5 moves from top to bottom, moves to certain position, the first guiding surface and the second guiding surface 611
Cooperation driving pulley mechanism 6 moves obliquely along the normal direction in trimming type face, until coaster cutter block 62 is connect with lower die cutter block 4
Touch, complete the trimming work of part.Stamping die of repairing provided in an embodiment of the present invention is for part trimming type face and horizontal direction
In the case of angle is more than 20 °, reduces the burr of part, improve the life-span of mold notch.
Preferably, coaster body 61 is provided with gripper shoe 612, coaster body 61 is suspended on by this gripper shoe 612
Upper mould 5.Coaster body 61 relies on gripper shoe 612 to be suspended on mould 5 it is possible to pass through further to arrange bottom surface guide plate 613 and side
Face guide plate 614 is slidably matched with upper mould 5, thus realizing the reciprocating motion of pulley mechanism 6.
Further, coaster body 61 is provided with breaker bolt 63, the mistake on described breaker bolt 63 and described upper mould 5
Hole cooperation is spacing, thus the dropping of pulley mechanism 6 when preventing gripper shoe 612 to lose efficacy.
Preferably, breaker bolt 63 and the via on upper mould 5 coordinate spacing may be accomplished by：This repaiies punch die
Tool also includes sleeve 64, is set on described breaker bolt 63, described sleeve 64 is provided with step 641, described step 641 blocks
In via on mould 5 on described.It is normal operating conditions when repairing stamping die, when gripper shoe 612 did not lose efficacy, breaker bolt 63
With 64 sets of sleeve in the vias, there is no active force between sleeve 64 and via.When gripper shoe 612 lost efficacy, pulley mechanism 6 has
The trend falling, now the step 641 on sleeve 64 ride over the edge of via, produce therebetween active force and play spacing work
With thus avoid pulley mechanism 6 drops it is ensured that the safety of production process.
It will be appreciated by persons skilled in the art that the quantity of breaker bolt 63 and described sleeve 64 can be answered according to actual
One or more with being set to, in the present embodiment, the quantity of breaker bolt 63 and sleeve 64 is all two.
Construction, feature and the action effect of the present invention, above institute are described in detail above according to the embodiment shown in schema
State only presently preferred embodiments of the present invention, but the present invention is not to limit practical range, every structure according to the present invention shown in drawing
Want made change, or be revised as the Equivalent embodiments of equivalent variations, when still covered with diagram without departing from description spiritual,
All should be within the scope of the present invention.
