Description

Multi-functional composite precision die

Technical field

The utility model is related to Tool and Die Technology more particularly to multi-functional composite precision dies.

Background technology

Mold, in industrial production being molded, being blow molded, squeezing out, die casting or the methods of forging forming, smelting, punching press obtain The various moulds and instrument of required product.In brief, mold is the instrument for formed article, and this instrument is by various parts It forms, different molds is made of different parts, it mainly realizes article by the change of institute's moulding material physical state The processing of shape.

Bending die is a kind of needs according to part shape, and blank is curved certain angle, the punching press of definite shape workpiece Mold.For a kind of partial shape bending angle, another part shape bends the workpiece of given shape, is rushed with bending die When molded, on the one hand it is usually necessary to use multiple mold Multi-step formings, and while using multiple mold how many times punching presses need into Workpiece is fixed in the multiple installation of row, and stamped workpieces dismantle workpiece, this causes process excessively cumbersome and causes production efficiency low, Improve the cost of production.On the other hand when using compound die come when avoiding multiple clamping Multi-step forming to improve processing efficiency It waits, structure of compound mould is complicated, and cost of manufacture is higher, is unfavorable for popularizing.At the same time, one it is expensive meet mold can only Workpiece with a type, and cannot match multiple workpiece types or cause match other types workpiece when error compared with Greatly, it is impossible to ensure high tight ness rating.

Accordingly, there exist a kind of demands, that is, develop a kind of multi-functional composite precision die, can at least solve the prior art The one or more of foregoing problems existing for middle bending mould.

Utility model content

The utility model provides multi-functional composite precision die, by adjustable work-piece detent mechanism and adjusts die body Can bending punching press be carried out to polytype workpiece in fact, improve the scope of application；While tight ness rating is ensured, and realize When carrying out multiple bendings if you need to multi-work piece, and a punching press need to be only carried out, the process for simplifying punching press improves production effect Rate reduces production cost.

In a first aspect, the utility model provides multi-functional composite precision die, including：Punch-pin；And with the punch-pin Corresponding cavity plate, the cavity plate have：Mounting base；And the die body in the mounting base is arranged at, which has：At least Two concave die cavities that bending punching press is carried out to workpiece；And at least a pair of adjustable work-piece detent mechanism being mutually matched；Its Described in the forming surface that is mutually inclined by two of concave die cavity form, connecting edge is formed between described two inclined surface, it is described recessed The adjusting die body detachably coordinated with die body is additionally provided on mould；
