Abstract

The utility model discloses a V-shaped part bending die comprising a male die, a rubber female die and a bottom plate. The rubber female die and the bottom plate are connected through an inner hexagon screw and located through a locating pin, a groove is formed in the bottom plate, a spring is placed in the groove and fixedly connected with a cross rod in an ejector rod, a vertical rod in the ejector rod penetrates through the V-shaped groove in the rubber female die and is contacted with a blank, and the blank and an end face of the V-shaped groove are located through a first stop pin and a second stop pin. The V-shaped part bending die enables a V-shaped part formed after being bent to be capable of automatically breaking away from the rubber female die, parts are not needed to be taken by hand time and time again, production efficiency is greatly improved, and safety is achieved.

Description

A kind of V-arrangement spare bending die

Technical field

The utility model relates to a kind of cold punching die of machining, particularly a kind of V-arrangement spare bending die.

Background technology

V-arrangement spare simple shape, flexural deformation is easy, but in the process of stamping die, rebound phenomenon takes place easily, and after promptly V-arrangement spare was taken out from mould, when not being subjected to mould constraint, interior angle can become greatly, has had a strong impact on precision.A kind of method of existing usefulness is to adopt the less relatively rubber die of hardness, makes blank be close to punch, to reduce non-deformation zone to influence springback.But behind the bending forming, V-arrangement spare easily pastes clothes on die, needs manually again and again V-arrangement spare to be taken out with hand, and efficient is very low, and has certain danger.

The utility model content

For solving the problems of the technologies described above, after the utility model provided a kind of bending forming, V-arrangement spare does not have rebound phenomenon to be taken place, and need not the V-arrangement spare bending die of artificial pickup simultaneously again.

For achieving the above object, the technical solution of the utility model is: a kind of V-arrangement spare bending die, comprise punch, rubber die, base plate, be connected by soket head cap screw between rubber die and the base plate and locate with alignment pin, be provided with groove in the base plate, place spring in groove, spring is fixedlyed connected with the cross bar in the push rod, montant in the push rod passes the V-shaped groove in the rubber die and contacts with blank, and blank is by first pin stop and second pin stop and V-shaped groove end face location.

The beneficial effects of the utility model are: blank is after being close to effect with punch on the rubber die, V-arrangement spare is ejected the V-shaped groove that leaves in the rubber die by the push rod that connects on the spring, avoided manually again and again V-arrangement spare being taken out with hand, production efficiency greatly improves, and safety.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: punch 1, rubber die 2, base plate 3, soket head cap screw 4, alignment pin 5, groove 6, spring 7, push rod 8, cross bar 81, montant 82, V-shaped groove 9, V-shaped groove end face 91, blank 10, first pin stop 111, second pin stop 112.

The specific embodiment

Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.

Embodiment:

As shown in Figure 1, a kind of V-arrangement spare bending die, comprise punch 1, rubber die 2, base plate 3, be connected by soket head cap screw 4 between rubber die 2 and the base plate 3 and with alignment pin 5 location, be provided with groove 6 in the base plate 3, place spring 7 in groove 6, spring 7 is fixedlyed connected with the cross bar 81 in the push rod 8, montant 82 in the push rod 8 passes the V-shaped groove 9 in the rubber die 2 and contacts with blank 10, and blank 10 is by first pin stop 111 and second pin stop 112 and V-shaped groove end face 91 location.

Operation principle of the present utility model is: after blank 10 is located with V-shaped groove end face 91 by first pin stop 111 and second pin stop 112, montant 82 in the push rod 8 contacts naturally with blank 10, spring 7 is in free state, when punch 1 is descending, blank 10 is bending forming under the effect of punch 1 and rubber die 2, and at this moment, spring 7 is in confined state, when punch 1 is up when leaving rubber die 2, the V-arrangement spare behind the bending forming ejects the V-shaped groove 9 that leaves in the rubber die 2 by push rod 8 with it.

Claims

1. V-arrangement spare bending die, comprise punch (1), rubber die (2), base plate (3), be connected by soket head cap screw (4) between rubber die (2) and the base plate (3) and locate with alignment pin (5), it is characterized in that: be provided with groove (6) in the described base plate (3), in groove (6), place spring (7), described spring (7) is fixedlyed connected with the cross bar (81) in the push rod (8), montant (82) in the described push rod (8) passes the V-shaped groove (9) in the rubber die (2) and contacts with blank (10), and described blank (10) is by first pin stop (111) and second pin stop (112) and V-shaped groove end face (91) location.
