Abstract
The utility model discloses a cold stamping parent-subsidiary die structure, belongs to the technical field of cold stamping dies, and aims to solve the problems of high manufacturing cost, high die maintenance cost, and low probability of ensuring the manufacture accuracy of the like series of products produced by the conventional dies. The cold stamping parent-subsidiary die structure structurally comprises a die capable of producing sharing structures in the series of products and provided with a cavity, and sets of inserts capable of producing difference structures in the series of products and fixed inside the cavity of the die, wherein one set of inserts is integrally matched and embedded with the cavity so as to form the lower die of the die, which is capable of producing corresponding stamping parts, and forming structures corresponding to the differences of the stamping parts are arranged on the inserts. The forming structure comprises a punching and forming structure, a half-cutting structure, a hole-flanging structure, and the like. The cold stamping parent-subsidiary die structure is suitable for cold stamping for the series of products.
Description
Technical field
The utility model belongs to the cold punching die technical field, relates in particular to a kind of cold stamping primary and secondary mode structure.
Background technology
Cold stamping is a kind ofly to utilize punch die on press various metals or non-metal sheet to be exerted pressure at normal temperatures to make its separation or distortion and obtain the stress metal processing method of definite shape part.The external shell of many products is on sheet metal and makes by the mould punching press.At present, Series Design is comparatively general in the product.Correspondingly, the structure of parts also has similar phenomenon in the series of products.At this moment, adopt many molds to come the series of products of production structure similar, both wastes of manpower have increased manufacturing cost again.In addition, when discrete structure spare in the mould damages, often to change, cause its maintenance cost height putting in order the group mould.
The utility model content
In existing mould production similar series product, manufacturing cost height, mold repair cost height, the difficult problem that guarantees to make precision.The purpose of this utility model is: provide a kind of and switch apace when being convenient to produce and the cold stamping primary and secondary mode structure of maintenance application.
The technical scheme that its technical problem that solves the utility model adopts is: it comprise the mould master mold that is provided with die cavity and can be fixed on the described mould master mold at least one insert, described insert to match to merge with described die cavity be set into one, form cold stamping primary and secondary mode structure; Described inserting is provided with and the corresponding molding structure in stamping parts otherness position.
Further, described molding structure comprises punching, molding structure, hemisection structure or hole flanging.
Further, described punching is shaped as circle, rectangle or polygon.
The beneficial effects of the utility model are: in view of series of products intercommunity structurally, the product mold design adopts some groups that increase matches with die cavity in mould to insert, and adopts dismountable structure, switches apace and maintenance application when being convenient to produce.Can after replacing is inserted simply, produce several different models in one mold; When mold notch has damage, only need to change the reparation of inserting, need not to change a whole set of mould, improved production efficiency.

The specific embodiment
Below in conjunction with the description that accompanying drawing carries out its exemplary embodiment, the above-mentioned feature and advantage of the utility model will become apparent and understand easily.
Embodiment 1: in conjunction with Fig. 1 to Figure 14 cold stamping primary and secondary mode structure of the present utility model is described, it comprises the mould master mold 1 that is provided with die cavity 100 and can match to merge with die cavity 100 inlays at least one 101(submodule of inserting of all-in-one-piece with mould master mold 1 respectively), the mould master mold 1 and 101 compositions of inserting can be produced the mould of corresponding stamping parts.Mould master mold 1 is used for producing the universal architecture in the series of products, and a plurality of 101 molding structures that are provided with corresponding stamping parts difference position of inserting are used for producing the otherness structure in the series of products.During production, 101 be embedded in the die cavity 100 of correspondence of mould master mold 1 inserting, and be fixed on the mould master mold 1 by screw, the product 2 of master mold production is fixed in the precalculated position on the mould master mold 1, and punch die carries out product 1 after punching obtains processing with 101 match the products 2 to master mold production of inserting.The shape that goes up the punching that is provided with of inserting in the present embodiment can be circle, rectangle or polygon, the quantity of punching and spacing all can be changed inserting of corresponding moulding according to the difference of series of products difference partial design, and then switch fast when reaching production and the purpose of maintenance application, among Fig. 6 and Figure 13, when having inserting of star punching, use makes product 24 in the series of products 2 102 the time, among Fig. 7 and Figure 14, when use has inserting 3 103 time of rectangle punching, make the product 35 in the series of products.
Embodiment 2: as different from Example 1, also molding structure, hemisection structure or hole flanging or the like can be set on inserting, to adapt to the different moulding needs of product.Wherein, molding structure be utilize insert with punch die on corresponding structure with plasticity blank punching press distortion, make required moulding; The hemisection structure is that the plasticity blank is carried out carrying out deformation processing again after the cutting of part; Hole flanging is to have on the blank of pre-manufactured hole, material is carried out pull and stretch, makes it translate into the shaping processing of erectting straight flange along certain curve.
Those skilled in the art will recognize that; the above-mentioned specific embodiment is exemplary; be in order to make those skilled in the art can better understand this patent content; should not be construed as is restriction to this patent protection domain; change or modify so long as disclose spiritual any being equal to of being done, all fall into this patent protection domain according to this patent.
