Abstract
The utility model discloses a blanking die without blanking and scrap, which can processbatten-shaped products and improve the material operating factor at the utmost degree. The blanking die without blanking and scrap of the utility model comprises a punch retainer arranged under an upper moulding board and a concave moulding board arranged on a lower moulding board. The blanking die without blanking and scrap is characterized in that the punch retainer is only connected with a force plug, and the concave moulding board is only provided with a guide board; the guide board is two long strip-shaped boards which are horizontally arranged at both sides of the wide direction of the concave moulding board.
Description
Technical field
The utility model relates to a kind of cold punching die, particularly a kind of used for color picture tube lath-shaped material blanking die.
Background technology
The plate cold stamping blanking die (as shown in Figure 1) of traditional used for color picture tube, first station passes through towards the locating hole punch towards locating hole, second station is by punch blanking (the sealing stamping-out goes out the part of wanting), and the 3rd station is by guide pin guide-localization (pilot hole is on waste material).Mould need adopt the structure of stripper.During the plate cold stamping, unnecessary group limit is arranged all around the punch forming part.Stock utilization is low, the product cost height.
Summary of the invention
The purpose of this utility model provides a kind of blanking die that does not have the blanking scrap (bridge), can improve stock utilization to greatest extent to the product of some lath shapes.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of blanking die that does not have the blanking scrap (bridge), comprise punch retainer that is arranged on the cope match-plate pattern below and the concave template that is arranged on the lower bolster, it is characterized in that, described punch retainer only is connected with punch, only be provided with guide plate on the described concave template, described guide plate is two rectangular plates, and is set in parallel in concave template width both sides.
In the such scheme, described parallel guide plate is arranged on along between the die cavity of an end of concave template length direction and concave template.
The advantage that the utility model is compared with traditional moulds is, be used high-precision feed appliance, when dividing the band shape material of scissors tool sub-cut to shear stamping-out to special use, between the die cavity of an end of concave template length direction and concave template, only needing very short parallel guide plate, just can guarantee that band shape expects to cut out width dimensions.Owing to guaranteed pushing precision with the feed appliance step pitch, saved in the mould design towards locating hole and guiding station, changing that former sealing blanking cuts out is to shear or cut-out, and does not need towards pilot hole, used stripping force is very little, has saved stripper.Mould structure after the improvement is simple, and manufacturing expense reduces, and is convenient to maintenance, has realized no waste material production.To band shape, rectangle semi-finished product and product, do not have at the stamping-out burr under the situation of specific (special) requirements, only cooperate the feed appliance sub-cut just can satisfy product width and length, and do not have the blanking scrap (bridge) with parallel guide plate.The utility model can improve stock utilization to greatest extent, makes some specific products, reaches 100% as stock utilization banded, rectangle.
Description of drawings
Fig. 1, Fig. 2 are a kind of existing blanking die structure chart.Wherein Fig. 2 is the vertical view of concave template among Fig. 1.
Fig. 3, Fig. 4 are the blanking die structure chart of the utility model after improving.Wherein Fig. 4 is the vertical view of concave template among Fig. 3.
Fig. 1 is in Fig. 4: 1. punch holder; 2. cope match-plate pattern; 3. guide pin bushing; 4. guide plate; 5. stripper; 6. lower bolster; 7. concave template; 8. guide pillar; 9. punch; 10. punch retainer; 11. towards the locating hole punch; 12. guide pin.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 3, Figure 4, the blanking die of a kind of improved no blanking scrap (bridge) of the present utility model, comprise punch retainer 10 that is arranged on cope match-plate pattern 2 belows and the concave template 7 that is arranged on the lower bolster 6, punch retainer 10 only is connected with punch 9, concave template 7 width both sides are arranged with two rectangular guide plates 4 in parallel, and the position of parallel guide plate 4 is in along between the die cavity of the left end of concave template 7 length directions and concave template.Distance between the parallel guide plate 4 defines the width of cutting out material, cooperates feed appliance at concave template 7 left ends, just can realize that continuous stamping does not have the product of the given shape of frame, as banded, rectangle.
Claims (2)
1. blanking die that does not have the blanking scrap (bridge), comprise punch retainer that is arranged on the cope match-plate pattern below and the concave template that is arranged on the lower bolster, it is characterized in that, described punch retainer only is connected with punch, only be provided with guide plate on the described concave template, described guide plate is two rectangular plates, and is set in parallel in concave template width both sides.
