Description
Technical field
The present invention relates to technical field of mold, more particularly, particularly a kind of drawing die structure of bonnet series products.
Background technology
Along with the develop rapidly of China's economy, electronics, the renewal upgrading of automobile and engineering machinery is more and more faster.Bonnet series products work in-process as shown in Figure 1, generally need to be by jet-bedding, stretch and cut three steps of waste material, is existingly generally by notching die, drawing die and cuts waste material mould and process respectively.But the problem that drawing die of the prior art exists when the product to after jet-bedding stretches is: owing to being provided with punch on the patrix of drawing die, and on counterdie, be provided with die, this processing method is because punch produces and clashes into die in descending process, easily make product produce more burr, affect the quality of product, increased follow-up complexity of cutting waste material operation.Therefore, be necessary to design a kind of novel drawing die structure.
Summary of the invention
The object of the present invention is to provide a kind of drawing die structure of bonnet series products, this structure has advantages of that crudy is high and burr is few.
In order to achieve the above object, the technical solution used in the present invention is as follows:
A kind of drawing die structure of bonnet series products, comprise stretching patrix and stretching counterdie, described stretching patrix comprises stretching die upper padding plate, be located at the stretching die of stretching die upper padding plate upper end, be located at the groove in described stretching die, be located at the stretching die loading and unloading material plate of groove upside, be located at the stretching die die mold insert of groove downside; Described stretching counterdie comprises stretching die lower bolster, be installed on the stretching die convex mould pad on stretching die lower bolster, be installed on the stretching convex die on stretching die convex mould pad, and be located at stripper under the stretching die outside stretching convex die, and described stretching convex die is corresponding with stretching die.
Preferably, described stretching convex die and stretching die die mold insert are loose fit.
Preferably, the upper end side of described stretching convex die is arcuate structure.
Compared with prior art, the invention has the advantages that: the present invention is provided with stretching die on patrix, on counterdie, be provided with stretching convex die, simultaneously in stretching die, be provided with stretching die die mold insert, the shortcoming such as more than make mould can avoid stretching poor product quality that the impact of die and stretching convex die brings and burr when work.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
Consult shown in Fig. 2, the drawing die structure of a kind of bonnet series products provided by the invention, comprise stretching patrix and stretching counterdie, described stretching patrix comprises stretching die upper padding plate 91, be located at the stretching die 92 of stretching die upper padding plate 91 upper ends, be located at the groove in described stretching die 92, be located at the stretching die loading and unloading material plate 93 of groove upside, be located at the stretching die die mold insert 94 of groove downside; Described stretching counterdie comprises stretching die lower bolster 98, be installed on the stretching die convex mould pad 97 on stretching die lower bolster 98, be installed on the stretching convex die 96 on stretching die convex mould pad 97, and be located at stripper 95 under the stretching die in stretching convex die 96 outsides, and described stretching convex die 96 is corresponding with stretching die 92.
In the present invention, described stretching convex die 96 is loose fit with stretching die die mold insert 94, and in use, stretching convex die 96 can conveniently be carried out punching stretch to the product in stretching die die mold insert 94.
In the present invention, the upper end side of described stretching convex die 96 is arcuate structure, can further reduce the generation of burr, improves the crudy of product.
