The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
With reference to Fig. 3 and Fig. 4, the present invention is applicable to the one-time formed diel of negative angle bending and comprises: lower module and upper module, concrete, lower module comprises from bottom to up: the die shoe 9 that is fixedly connected sequentially, lower bolster 10, lower bolster 11, upper module comprises from bottom to up: stripper plate 12, baffle plate 13, fixed head 14, upper padding plate 15, upper bolster 16, wherein, stripper plate 12 is fixedly connected with baffle plate 13, and fixed head 14, upper padding plate 15, upper bolster 16 are fixedly connected sequentially.Be provided with Bending punch 2 in fixed head 14, Bending punch 2 is obliquely installed, and inclination angle a(refers to Bending punch 2 and horizontal plane angulation) consistent with the product bending angle; Accordingly, be provided with bending in the lower bolster 11 and enter piece 3, bending enter piece 3 have the supporting surface that be used for to support material 1 main body of level and inclination be used for cooperates the compressive plane 301 that material 1 is squeezed into negative angle with Bending punch 2, angle a and the product bending angle of formation are consistent between supporting surface and the compressive plane 301.
As a kind of preferred scheme, the end that Bending punch 2 contacts with material 1 is smooth arc, and the compressive plane of material 1 can be not damaged in the time of can guaranteeing Bending punch 2 extruding material 1, thereby guarantee product yield.
After the negative angle punching press is complete, upper module and lower mould splits from, this moment, the product main body flushed with lower die face, dogleg section is positioned at the lower die face below, for convenient product is taken out in lower module smoothly, as a kind of preferred scheme, bending enters piece 3 and is slidingly connected with lower bolster 11, and vertically slide, thereby product integral body can be ejected lower die face, very convenient taking-up product.
As a kind of preferred scheme, bending enters piece 3 ejecting products and realizes by ejector spring 6.Concrete, an ejector spring 6 vertically is set in die shoe 9, enter to be fixedly connected with again a knock pin 5 between the piece 3 in ejector spring 6 and bending.When mould was closed, ejector spring 6 was in compressive state; When mould was opened, ejector spring 6 returned to nature, will enter piece 3 with its knock pin that is fixedly connected with 5, the bending that is fixedly connected with knock pin 5 and upwards eject, thereby product is ejected lower die face.
For different products, may need different bendings to enter piece 3, in order to make things convenient for its replacing, bending enters between piece 3 and the knock pin 5 and can be threaded connection, concrete, enter the bottom tapping of piece 3 in bending, form again the external screw thread that enters the screw-internal thread fit of piece 3 with bending in the outside of knock pin 5 and get final product.
As a kind of preferred scheme, the bottom of ejector spring 6 is provided with plug screw 7.Plug screw 7 is upwards tightened from the bottom of die shoe 9, that is to say, the bottom of die shoe 9 is formed with the through hole for plug screw 7 turnover, if when needing to change ejector spring 6, only need take off plug screw 7 along this through hole, change and install again plug screw 7 after complete and get final product, need not whole lower module is done dismounting, flexible operation, very convenient use.
As a kind of preferred scheme, mould of the present invention also includes return spring 8, and return spring 8 is arranged between baffle plate 13 and the upper bolster 16, and it can assist resetting of upper bolster 16, and the separating of fixed head 14 and baffle plate 13 when being conducive to mould and opening.
Because being compressive plane 301 interactions that utilize Bending punch 2 and bending to enter piece 3, the product bending realizes, and the thickness of product is generally all less, for the yield that guarantees product and the flexibility ratio of drift, usually the thickness of Bending punch 2 is also all less, but its intensity also will have certain guarantee, so, as a kind of preferred scheme, Bending punch 2 its thickness that do not stretch out the part of module among the present invention stretch out the thickness of the part of upper module greater than it, have so not only guaranteed the flexibility of drift but also have guaranteed the intensity of its punching press.
Need to prove that above-described embodiment does not limit the present invention in any form, all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
