The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
A kind of have a upwards progressive die of bending forming mechanism, comprising: upper bolster 1, die shoe 2, be arranged at the decompressor under upper bolster 1, with respect to decompressor and be arranged at the shaped device on die shoe 2.
Decompressor forms to be had: be positioned the stamping parts under upper bolster 1, as a kind of preferred, the stamping parts top is bending punching pin 3; Be fixed in upper bolster 1 and movablely through stamping parts, take off the material assembly; Shaped device forms to be had: be fixed in the slide assemblies on die shoe 2, be fixed on die shoe 2 and be close to the foldable component of slide assemblies both sides; The top of slide assemblies and the top of foldable component are in the same plane.It should be noted that: purpose in the same plane is: at first, be positioned at same plane and be suitable for the stable of product and put, make when punching press, product is held, and can not move; Secondly, be positioned at same plane and be convenient to determine the bending angle of product according to the shape of first fold sinus mouth 401, the second bending breach 501.
Foldable component forms to be had: be placed in the first bending part of slide assemblies one side, be placed in the second bending part of slide assemblies opposite side; The first bending part, the second bending part are formed with first fold turn of bilge, the second bending part near the position of slide assemblies.As a kind of preferred, the first bending part, the second bending part are the first folded block 4, the second folded block 5, and first fold turn of bilge, the second bending part are first fold sinus mouth 401, the second bending breach 501.It should be noted that, the shape of bending arbitrarily arranges the shape of first fold sinus mouth 401, the second bending breach 501 as required.
Slide assemblies forms to be had: fixing and through the first elastic component on die shoe 2, and be close between the first folded block 4, the second folded block 5 and be placed in the sliding part on the first elastic component.As a kind of preferred, the first elastic component is the first nitrogen spring 6, and sliding part is buoyant piece 7.It should be noted that, the nitrogen spring that mould is used is a kind of novel elastic assembly take high pressure nitrogen as working media, can simplify Design of Dies and manufacture, facilitates the mould install and adjust, extends the service life of mould, guarantees the stable of product quality.Buoyant piece 7 is set between the first nitrogen spring 6 and product can stable prod, and alleviates the impulsive force to the first nitrogen spring 6.
Taking off the material assembly forms and to have: be fixed in upper bolster 1 and be active in the second elastic component in bending punching pin 3, being connected in the second elastic component and protruding from the ejection piece of bending punching pin 3.As a kind of preferred, the second elastic component is the second nitrogen spring 8, and ejection piece is push rod 9.To take off the setting of material assembly and be applied in bending punching pin 3, and simplify the structure of stripper, and improved the effect of taking off material; In addition, push rod 9 protrudes from bending punching pin 3 bottoms under general state, and when bending punching pin 3 contact products started punching press, push rod 9 had the effect of guiding and firm product; The second nitrogen spring 8 is fixed on upper bolster 1 by bolt 12, has guaranteed like this equipment stability in process of production.
A kind of bending and molding equipment also comprises: be connected in the first elastic component and be fixed in the Buffer Unit under die shoe 2, Buffer Unit forms to be had: a plurality of bolsters.As a kind of preferred, bolster is feet 10.Wherein there is a feet 10 to be fixed in the first nitrogen spring 6 lower ends, slowed down the impulsive force of 3 pairs of the first nitrogen springs 6 of bending punching pin, extended the life-span of the first nitrogen spring 6.
bending starts, when mould is closed (as Fig. 1, shown in Figure 2), upper bolster 1 descends, at first push rod 9 in bending punching pin 3 touches the surface of product, push rod 9 presses to product and 7 laminatings of buoyant piece, upper bolster 1 continues to descend, the stressed retraction bending of push rod 9 punching pin 3 inside, the first folded block 4 and the second folded block 5 are close in the product both sides, upper bolster 1 continues to descend, product is pressed into to first fold sinus mouth 401 with bending punching pin 3 and the second bending breach 501 carries out moulding, buoyant piece 7 descends with the strength that bending punching pin 3 transmits, the first nitrogen spring 6 is pressed down to contraction, the mould closure completes, the product bending that makes progress completes.
Taking off material process starts, mold open, the first nitrogen spring 6 loses the pressure resilience that makes progress, buoyant piece 7 is ejected product between the first folded block 4 and the second folded block 5, due to mold open, push rod 9 loses stressed, and the second nitrogen spring 8 ejects bending punching pin 3 by push rod 9, and push rod 9 breaks away from bending punching pin 3 by product; Taking off material has completed.Be applicable to the upwards bending and molding equipment end-of-job of slab.The course of work is succinct, fast, stable.
The present invention has used the equipment with a small amount of part and simple structure assembling, cost and energy consumption have been reduced, but but realized, efficiently upwards bending and molding stable at the steel plate more than 3.0 for thickness, and shortened the mode transfer time and improved simultaneously dimensional accuracy; Thereby production efficiency and the market competitiveness have been improved.
Above demonstration and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and 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.
