Description
Technical field
The utility model relates to drawing die technical fields, prevent corrugated drawing at the top of drawing in particular to one kind
Prolong mold.
Background technique
Currently, beam product structure biggish for some top drops can not be using molding since top drop is larger
Technique is completed, and drawing and moulding technique need to be used.And existing upper mold is conventional drawing mold structure, and without special precompressed mechanism, zero
The big position corrugation of drop is serious at the top of part, is molded into bottom and generates stack.
In product forming process, since structure is needed there are larger drop at the top of product, and the spy of such product itself
Property cause its in drawing process easily generate corrugation stack phenomenon.Specifically during drawing and moulding, high point is first at the top of product
Touching expects that the material needed in forming process is more, and touches material at the top of product after low spot, and the material needed is less, and height is low at the top of product
When difference is larger, since demand of the adjacent area to material has big difference, extra material is generated in product low dot location, is had more
Material is had nowhere to go, therefore shows as product corrugation stack phenomenon.
Summary of the invention
In consideration of it, the utility model proposes one kind to prevent corrugated drawing die at the top of drawing, it is intended to solve top and fall
The biggish product of difference generates corrugation stack phenomenon in drawing process, causes the debugging of mold later period difficult, rectifies and improves at high cost ask
Topic.
On one side, the utility model proposes one kind to prevent corrugated drawing die at the top of drawing, comprising: for top
The biggish product of clan's difference carries out upper cavity die, the lower punch of drawing, wherein close to any of the product on the inside of the upper cavity die
Side is provided with precompressed mechanism, and precompressed mechanism one end is connect with the upper cavity die, and the other end is contacted with the product.
Further, the precompressed mechanism includes nitrogen gas spring mounting base, nitrogen gas spring and preloading block, the nitrogen gas spring
It is connect on the inside of mounting base and the upper cavity die, the nitrogen gas spring is connect with the nitrogen gas spring mounting base, and the preloading block is logical
It crosses the nitrogen gas spring to connect with the nitrogen gas spring mounting base, the preloading block is also contacted with the product.
Further, one end of the nitrogen gas spring is plugged in the nitrogen gas spring mounting base, and the other end is plugged in institute
It states in preloading block, the nitrogen gas spring is used to control the pressure and stroke of the preloading block.
Further, the preloading block is used to the tablet for making the product being compacted to the lower punch.
Further, the product includes beam class product.
Further, the precompressed mechanism, which is arranged, is easy corrugated side in the product.
Compared with prior art, the beneficial effects of the utility model are, by increasing on the upper cavity die of drawing die
As soon as precompressed mechanism will be pressed on lower punch at the top of product before product generates corrugation stack, prevent product in drawing
Corrugation stack phenomenon is generated in journey, guarantees the flatness at the top of product, is promoted parts quality, is reduced the scrappage of product.
Further, by the way that precompressed mechanism is arranged in drawing die, the utilization rate of product material is improved, is obviously improved
The quality of product, effectively reduces the scrappage of product, and reduces the debugging rectification cost in drawing die later period, shortens mould
Has the development cycle.
Detailed description of the invention
By reading the following detailed description of the preferred embodiment, various other advantages and benefits are common for this field
Technical staff will become clear.The drawings are only for the purpose of illustrating a preferred embodiment, and is not considered as practical to this
Novel limitation.And throughout the drawings, the same reference numbers will be used to refer to the same parts.In the accompanying drawings:

Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.It should be noted that in the absence of conflict, the implementation in the utility model
Feature in example and embodiment can be combined with each other.It is below with reference to the accompanying drawings and in conjunction with the embodiments practical new this is described in detail
Type.
In conjunction with shown in Fig. 1-4, the utility model embodiment, which provides one kind, prevents corrugated drawing die at the top of drawing, draws
Prolonging mold includes upper cavity die 1 and lower punch, and upper cavity die 1 and lower punch are used to carry out drawing behaviour to the biggish product of top drop 3
Make, wherein the inside of upper cavity die 1 is provided with precompressed mechanism 4 close to any side of the product 3,4 one end of precompressed mechanism with it is described
Upper cavity die 1 connects, and the other end contacts with the side of the product 4, held out against product 3 on lower punch by precompressed mechanism 4.Tool
Body, one end of precompressed mechanism 4 is fixed on the medial surface of upper cavity die 1, and the other end is contacted with the side side of product 3.
It is understood that it is folded to generate corrugation in product by increasing by a precompressed mechanism on the upper cavity die of drawing die
It will be just pressed on lower punch at the top of product before material, prevent product from generating corrugation stack phenomenon in drawing process, guarantee to produce
Flatness at the top of product promotes parts quality, reduces the scrappage of product.
Specifically, precompressed mechanism 4 includes nitrogen gas spring mounting base 5, nitrogen gas spring 6 and preloading block 7, the nitrogen gas spring
It is connected on the inside of mounting base 5 and the upper cavity die 1, for fixing nitrogen gas spring 6, in the specific implementation, on 1 medial surface of upper cavity die
A groove is opened up for placing nitrogen gas spring mounting base 5, is connected as one the two；The nitrogen gas spring 6 and the nitrogen bullet
