Description
Technical field
The utility model belongs to technical field of mold, relates to a kind of flanging die for processing mobile phone backboard, particularly relates to a kind of mould for ultrathin backboard outward flanging.
Background technology
In the process of panel beating product, process the product of some similar Fig. 1 sometimes, this product is 4.5 cun of ultra thin handset backboards; This product adopts only has the stainless steel ultra-thin materials of the thick 3/4H of 0.10mm to make, and the surrounding of product all needs outward flanging.But the flatness of this product is less than or equal to 0.15mm, product size is large and thin, and progressive die material strip connects material level and puts very little, affects the positioning precision of material strip.And the portion of product needs blank bending, the edge of a knife is comparatively thin, only has 0.37mm, as used common die flange, is then difficult to realize, scrappage can be caused too high, add difficulty to die sinking design.
Therefore, how solving the problem, is the content that those skilled in the art important research.
Summary of the invention
For overcoming above-mentioned deficiency of the prior art, the utility model object is to provide a kind of mould for ultrathin backboard outward flanging.
For achieving the above object and other relevant objects, the utility model provides a kind of mould for ultrathin backboard outward flanging, and the mould of described outward flanging comprises cope match-plate pattern, upper padding plate, train wheel bridge, baffle plate, upper de-plate, lower bolster, lower bolster and die shoe; Also comprise Bending punch combination; Described Bending punch comprises the first drift, the second drift and centre punch; Described first drift is two, is apart symmetrical arranged; Described second drift is also two, is symmetricly set on the two ends of described first drift, and is spliced to form border structure; Described centre punch is located at and is spliced to form border structure inside by the first described drift and the second drift, and with the mating shapes of described first drift and the second drift.
In technique scheme, related content is explained as follows:
1, in such scheme, the cross section of described first drift is isosceles trapezoid, and two waists of described isosceles trapezoid are inwardly recessed respectively, forms a drift with the upper base of isosceles trapezoid.
2, in such scheme, the cross section of described second drift is also isosceles trapezoid, and two waists of described isosceles trapezoid and the middle part of upper base are inwardly recessed respectively, and the upper base of isosceles trapezoid forms two drifts.
3, in such scheme, described centre punch is rectangle; With described first drift with the second punch shape is concavo-convex matches on four limits of described rectangular centre drift.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
The utility model simplifies mould structure, reduces assembly difficulty and the manufacturing cost of mould, improves die life, flange bending that is ultra-thin, degree of precision can be completed, shaping efficiency is high and scrappage is extremely low, and formed precision is high, meets the requirement of client completely.
