The quantity for stating guide nail 21 is more than or equal to 2, and the positioning hole that guide nail 21 is formed with positioning hole punch-pin 22 in raw band
Match somebody with somebody.
(3) the blanking mold insert 24 protrudes the bottom surface of the stripper 5；The cross-sectional diameter of the blanking mold insert 24 is
d1, the cross-sectional diameter d of the blanking die 102, a diameter of d, d of target sheet stock1+ 0.05=d, d2- 0.05=d.
(4) after the part of the upper die and the part of the lower die matched moulds, the blanking mold insert 24 and the blanking die 10 it
Between clearance distance be equal to raw band thickness.
In the present embodiment, the sheet stock of pre-cut in material strip is ejected by pre-cut by the elastic force of back-moving spring 15 by binder block 14
The plane of cavity plate 13.Material strip 18 is ejected concave template plane by material lift post 17, is easy to self-feeding.
The utility model is a set of progressive die.Mould is by rushing the works such as positioning hole, pre-cut sheet stock, Blanking, material strip cut-out
The blanking forming process of product is completed in position, and final products also need other shaving die to be cutting into finished product.Rush positioning hole and be easy to mould
Feeding positions in tool.The punch-pin of pre-cut sheet stock station has an arc notch, and its effect is to cut sheet stock blank, only stays 2 points
Connected together with material strip, be easy to feeding.The stripper of Blanking station has an insert of protrusion, and mold insert is by falling on concave template
Material cavity plate and stretching cavity plate are spliced, and first cut the sheet stock being connected on raw band on stretching cavity plate during matched moulds, then again by
Stretching convex die and stretching cavity plate mold insert are by sheet stock drawing and forming.Material strip cut-out is by the billot cut-out of scrap (bridge), is easy to collect and gives up
Material.Because stretching process needs to stretch oil lubrication, station is provided with oil filler point before the stretching, and sheet stock is soaked into upper drawing oil.
Using the utility model mould, according to this through overshooting the stations such as positioning hole, pre-cut sheet stock, Blanking, material strip cut-out
The blanking forming process of product is completed, obtains target product such as Fig. 5 to Fig. 7.The first step rushes positioning hole station by positioning hole punch-pin
22 and rush positioning hole cavity plate 16 raw band is gone out into 2 positioning holes, 21 correctings are followed closely by guide, realize the feeding positioning of material strip.The
Two steps realize sheet stock pre-cut by pre-cut sheet stock station by precut punch 23 and pre-cut cavity plate 13, and by binder block 14 and back-moving spring
The sheet stock ejection concave template plane of 15 pre-cut.Precut punch 23 has an arc notch (see Fig. 3), and its effect is by sheet stock blank
Cut, only stay 2 points to be connected together with material strip, be easy to feeding.3rd step Blanking station is recessed by blanking mold insert 24 and blanking
The sheet stock of pre-cut is cut off raw band by mould 10 first, then by stretching convex die 25 and stretching cavity plate 11 by sheet stock drawing and forming, production
Product 12 drop out out of lower nib.Blanking mold insert 24 is higher by 0.5 than stripper 5, and smaller than sheet stock diameter by 0.05, to be put into raw material
Among band.Blanking die 10 is bigger than sheet stock diameter by 0.05, and so that sheet stock is put into wherein, and blanking mold insert 24 exists with blanking die 10
Gap after matched moulds is equal to material thickness, so as to which in stretching, the bottom surface of blanking mold insert 24 can play a part of binder.Stretch convex
Mould 25 and stretching cavity plate 11 use wolfram steel material, cavity plate back-kick step, so as to inloading part, see Fig. 4.4th step is by blank band
Knife 9 cuts off the billot of scrap (bridge) under upper slitter 26 and blank band, is easy to collect waste material, thus completes the press work of product.
Because stretching process needs to stretch oil lubrication, station is provided with oil filler point 29 before the stretching, is injected laterally drawing oil from mould, makes sheet stock
Drawing oil in leaching, is shown in Fig. 4.
By using above-mentioned technical proposal disclosed in the utility model, following beneficial effect has been obtained：
The utility model solves the problems, such as that the draw efficiency first of existing audiphone shell class part is relatively low.This practicality is new
Type makes this kind of stretched parts be processed by the way of progressive die by optimizing production process and mould structure.This processing mode
Stock utilization it is higher, product quality is stable, and efficiency compared with traditional handicraft can several times improve.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching should also regard the scope of protection of the utility model.
