Main purpose of the present utility model is to provide a kind of stamping die that can improve high convex closure Workpiece shaping effect.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of high convex closure workpiece stamping die, comprise patrix, described patrix is divided into the first mould district successively, second mould district and the 3rd mould district, be provided with for the fabrication hole cutting knife in moulding process hole and the first binder block around described fabrication hole cutting knife in described first mould district, the draw punch for shaping convex closure and the second binder block around described draw punch is provided with in described second mould district, be provided with in described 3rd mould district for by distortion after the holes of products cutting knife of fabrication hole correction and the 3rd binder block around described holes of products cutting knife, described fabrication hole position corresponds in described Convex range, described fabrication hole shape is included in described holes of products shape.
Concrete, described first mould district surrounding is provided with the locating hole cutting knife for cutting out locating hole.
Further, described locating hole cutting knife top is inclined-plane shape.
Further, described second mould district and the 3rd mould district are equipped with the positioning convex of corresponding described locating hole.
Further, described positioning convex top is taper type.
Concrete, described 3rd mould district is also provided with the profile cutting knife being positioned at described 3rd binder block periphery.
Adopt technique scheme, the beneficial effect of technical solutions of the utility model is:
Fabrication hole required in forming process, by the change of mould, is opened in holes of products, becomes from inside to outside by the type of flow of material from ecto-entad by the utility model, reduce deformed region, reduce distortion risk, ge punch structure is simple simultaneously, and die sinking is convenient.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 4 and Figure 5, one of the present utility model high convex closure workpiece stamping die, comprise patrix 2, patrix 2 is divided into the first mould district 21 successively, second mould district 22 and the 3rd mould district 23, the fabrication hole cutting knife 211 for moulding process hole and the first binder block 212 around fabrication hole cutting knife is provided with in first mould district 21, the draw punch 221 for shaping convex closure 11 and the second binder block 222 around draw punch 221 is provided with in second mould district 22, be provided with in 3rd mould district 23 for by distortion after the holes of products cutting knife 231 of fabrication hole correction and the 3rd binder block 232 around holes of products cutting knife 231, fabrication hole position corresponds in convex closure 11 scope, fabrication hole shape is included in holes of products 13 shape.
The molding process of this stamping die is:
(1) fabrication hole is rushed: the position utilizing ge punch 211 to need to go out holes of products 13 at sheet material 100 punches out the fabrication hole that profile is less than holes of products 13;
(2) high convex closure stretches: utilize draw punch 221 to be stretched by the sheet material 100 after previous step punching, forms high convex closure 11 structure of product;
(3) holes of products is rushed: holes of products 13 gone out by the sheet material 100 after utilizing holes of products drift 231 previous step to be stretched, and makes the fabrication hole contour revising of stretcher strain profile needed for holes of products 13.
In the art, inside contract 3-5mm obtain with the fabrication hole profile of Experience Design by holes of products 13 profile, this is embodied by the design relation of ge punch 211 and holes of products drift 231, the non-band shape of ge punch 211 cross section structure, and structure is simple, and die sinking is convenient; Due to the existence of fabrication hole on sheet material 100, in high convex closure drawing process, because material peripheral is pushed down by the second binder block 222, the material at fabrication hole place can flow from inside to outside and supply the thickness loss in drawing process, fabrication hole then occurs irregularly to extend out distortion, this strong deformation only occurs in convex closure 11 inside region, and therefore other fractional distortion risks of product reduce; Final product hole drift 231, by unnecessary fabrication hole edge deletion, leaves neat holes of products 13 profile.
As shown in Figure 4 and Figure 5, the first mould district 21 surrounding is provided with the locating hole cutting knife 213 for cutting out locating hole 101; Second mould district 22 is provided with the first positioning convex 223 of corresponding locating hole 101; 3rd mould district 23 is provided with the second positioning convex 233 of corresponding locating hole 101.Sheet material 100 cuts out locating hole 101 in the first mould district 21 simultaneously, first positioning convex 223 utilize locating hole 101 to locate position that sheet material 100 is transported to the second mould district 22, the second positioning convex 233 utilize locating hole 101 to locate position that sheet material 100 is transported to the 3rd mould district 23.Because locating hole 101 position is away from fabrication hole, and there is the second binder block 222 binder effect in stretching, therefore do not worry locating hole 101 change in location and problem is forbidden in the location of bringing.
As shown in Figure 5, locating hole cutting knife 213 top is inclined-plane shape.Such locating hole cutting knife 213 cuts out locating hole 101 can than smoothly.
As shown in Figure 5, positioning convex (223,233) top is taper type.Guiding function can be played in the taper type top of positioning convex (223,233), makes it pass automatic fine tuning sheet material 100 position in locating hole 101 process, prevents from hitting mould or breaking locating hole 101 so that locate failure.
As shown in Figure 4 and Figure 5, the 3rd mould district 23 is also provided with the profile cutting knife 234 being positioned at the 3rd binder block 232 periphery.Such 3rd mould district 23 can cut out all profiles of workpiece 1 in the lump, makes workpiece 1 directly can enter packet assembler, accelerates speed of production.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
