Abstract

The invention discloses a flanging and punching double acting composite die, which aims at providing a composite die which can realize the punching and upward flanging of a work piece in a working procedure so as to improve production efficiency, and reduce manufacturing cost. The key points of the technical proposal are that an upper die base(1) is provided with a tapered wedge driving face(11) which can downward push the outer tapered wedge face of a tapered wedge slide block(7) to make horizontal movement toward the center of a lower die base(2); and an upward movement tapered wedge slide block(8) is arranged above the inner tapered wedge face of the tapered wedge slide block(7); driven by the tapered wedge active force of the upward movement tapered wedge slide block, the upward movement tapered wedge slide block drives a flanging embedded block(6) in a gap on the upper end thereof to move upward together, a pressing piece arranged below a pressing-material machine(3) is upward flanged, at the same time, a punching concave die(4) arranged on the upper die base(1) and a punching concave die(5) arranged on the lower die base(2) punch the work piece.

Description

Flanging eyelet work dual-movement composite mold

Technical field

The present invention relates to the composite die of a kind of punching and flange.

Background technology

In the prior art, carrying out punching on the same product and during, needing punching operation and two operations of overturning process upwards usually to upper overturning.Therefore, often need two molds, i.e. perforating die and flange die.With two molds product is carried out punching and flange respectively, its conspicuous weak point is the production cost that has increased product.And, owing to adopt two procedures, in the per pass operation, certainly will relate to orientation problem, and twice location will inevitably cause the precise decreasing of product processing.

Summary of the invention

Task of the present invention is to propose a kind of can enhancing productivity, and reduces manufacturing cost, can finish simultaneously in an operation to the product punching with to the composite die of upper overturning.

The technical solution adopted for the present invention to solve the technical problems is: a kind of flanging eyelet work dual-movement composite mold, comprise, be separately positioned on piercing punch on the end face and punching concave die between upper bolster and the die shoe, it is characterized in that, described upper bolster is provided with downward promotion wedge slide block outside cammed surface, wedge drive surface to the motion of die shoe central horizontal, be positioned at the inboard cammed surface of wedge slide block top on move the wedge slide block, under the driving of its wedge active force, flange insert in its upper end breach is upwards driven together, the product that compresses that is arranged on below the eccentric swage is implemented to upper overturning, be installed in the piercing punch on the upper bolster simultaneously and be installed in punching concave die on the die shoe the product punching.

The present invention has following beneficial effect.

The present invention is by the acting in opposition (be about to moving downward of lathe slide block and change over moving upward of slide block) of reverse Wedge mechanism, utilize the relativity between flange insert and the eccentric swage, finish product is carried out to upper overturning, by the relative motion between piercing punch and the punching concave die product is carried out punching, disposablely in same operation finished the punching of product and to upper overturning work.Thereby overcome prior art two molds, two procedures is finished the drawback of punching and flange at least.Because at same set of mould, an operation is finished punching and flange two procedures by one-time positioning, has not only saved the manufacturing of a mold, has improved production efficiency of products greatly, has reduced the manufacturing cost of product, but also has improved the machining accuracy of product.

Description of drawings

Fig. 1 is the organigram before the flanging eyelet work dual-movement composite mold flange of the present invention punching.

Fig. 2 is the bottom dead centre view after Fig. 1 mould is finished the flange punch work.

In the accompanying drawing: 1. upper bolster, 2. die shoe, 3. eccentric swage, 4 piercing punches, 5. punching concave die, 6. flange insert, 7. wedge slide block moves the wedge slide block on 8., 9. retracting spring, 10. guide plate, 11. wedge drive surface, 12. wedge drive surface, 13. center stand column.

The specific embodiment

Consult Fig. 1, Fig. 1 has described a most preferred embodiment of flanging eyelet work dual-movement composite mold of the present invention.And shown duty before the mould flange punching.This flanging eyelet work dual-movement composite mold comprises being separately positioned on piercing punch 4 on the end face and punching concave die 5 between upper bolster 1 and the die shoe 2.On the upper and lower end face between upper bolster 1 and the die shoe 2, be respectively arranged with at least one piercing punch 4 and punching concave die 5.In the inboard of upper bolster 1 lower surface inner chamber, be provided with and the consistent wedge drive surface 11 in cammed surface angle of inclination, wedge slide block 7 outside.Be positioned at the inboard cammed surface of wedge slide block 7 top on move wedge slide block 8 and be provided with equally and the consistent wedge drive surface 12 in described inboard cammed surface angle of inclination.Wedge slide block 7 is distributed in the both sides of die shoe 2 bottom die cavities, with die shoe 2 base center stand column 13 symmetries.For reducing friction, between the contact-making surface of all cammed surface, all be provided with prior art guiding guide plate 10 commonly used usually.The cross section of wedge slide block 7 be one based on trapezoidal irregular polygon, and be positioned at the both sides of die shoe 2 base center stand column 13 in opposite directions.For making things convenient for the two-way horizontal motion of wedge slide block 7, on die shoe 2 die holder bottom surfaces, be fixedly connected with the retracting spring 9 that links to each other with wedge slide block 7 bottom side planes in die shoe 2 baseplanes.This retracting spring 9 can be the backhaul nitrogen spring.

When upper bolster 1 moves downward, wedge slide block 7 cammed surface on the both sides wedge drive surface 11 contact die shoes 2, wedge slide block 7 is subjected to the horizontal applied force of the direction of arrow, move to die shoe 2 central horizontal, promotion is positioned at the wedge drive surface 12 of wedge slide block 7 inboard cammed surface tops, make and move wedge slide block 8 under the driving of its wedge active force, flange insert 6 in its upper end breach is upwards driven together, implement to upper overturning being arranged on the eccentric swage 3 following products that compress, be installed in piercing punch 4 and the 5 pairs of product punchings of punching concave die that are installed on the die shoe 2 on the upper bolster 1 simultaneously.

During work, the eccentric swage 3 that is contained in upper bolster 1 is at first pushed down product to be processed, the wedge drive surface of upper bolster 1 is moved straight down, promoting both sides wedge slide block 7 moves horizontally to die shoe 2 base center stand column 13, moving wedge slide block 8 in the promotion moves straight up, make to be contained in the flange insert 6 of moving on the wedge slide block 8 and to move straight up, finish turn-up process.Be installed in the piercing punch 4 on the upper bolster 1 simultaneously and be installed in punching concave die 5 on the die shoe 2 and finish punch work product.

Shown in Figure 2 is bottom dead centre state after mould is finished the flange punch work, and after this, patrix moves straight up with press ram, and slide block 7 is under the effect of backhaul nitrogen spring 9, and along continuous straight runs returns original state shown in Figure 1 to left movement.On move wedge slide block 8 and dress flange insert 6 is thereon moved straight down, return original state shown in Figure 1.
