Abstract

A kind of die cutting die without scrap (bridge), including top mold frame and lower mold holder, guide pin bushing is provided with the downside of the top mold frame, the guide pillar matched with the guide pin bushing is provided with the upside of the lower mold holder, the top mold frame is provided with mould, and the lower mold holder is provided with lower mould, it is characterised in that, the upper mould is followed closely provided with positioning and guiding, and the lower mould is provided with follows closely the positioning hole matched with positioning and guiding;The upper mould is provided with cutting knife, and the lower mould is provided with the outside of some die cavitys, the die cavity and leaves scrap (bridge), without scrap (bridge) between the die cavity and die cavity.By cancelling the scrap (bridge) between die cavity and die cavity, the scrap (bridge) between workpiece and workpiece is namely eliminated, the scrap (bridge) being omitted from is arranged between workpiece and clout side, so will not both increase raw material size, also the stability of binder is increased, it is ensured that the part of production is qualified.

Description

A kind of die cutting die without scrap (bridge)
Technical field
The utility model belongs to field of machining, and in particular to a kind of die cutting die without scrap (bridge).
Background technology
Die cutting die is a kind of mould common during material is molded, and mould is when designing stock layout, in order to compensate feeding error, Billot is set to have reliable positioning to die hole, the technique clout that can be left between workpiece and workpiece and workpiece and billot side, To ensure that process shape is complete, preferable crudy is obtained.When the hardness of raw material is raised, the thickness and length of part in addition Increase, blanking pressure becomes big, and in the case where mould structure does not change, the width of particularly raw material does not have increased situation Under, old technique punching press raw material scrap (bridge) amount is not enough, and the pressure-plate-force of upper mould can not push down the waste material side of part, and causing should in the middle of part The removed portion of material is drawn into die cavity, so as to cause size to be deteriorated, if increase raw material width, can cause cost to increase Plus.
Utility model content
The utility model provides a kind of die cutting die without scrap (bridge), solves and runs into high rigidity raw material, and die cavity is variable The underproof problem of shape, part, while also not increasing raw material width, reaches the not increased effect of cost.
In order to solve the above technical problems, the utility model employs following technical scheme:A kind of blanking die without scrap (bridge) It is provided with to be provided with the upside of guide pin bushing, the lower mold holder on the downside of tool, including top mold frame and lower mold holder, the top mold frame and matches with the guide pin bushing Guide pillar, the top mold frame is provided with mould, and the lower mold holder is provided with lower mould, and the upper mould is followed closely provided with positioning and guiding, described Lower mould is provided with follows closely the positioning hole matched with positioning and guiding;The upper mould is provided with cutting knife, and the lower mould is provided with some die cavitys, the mould Scrap (bridge) is left on the outside of chamber, without scrap (bridge) between the die cavity and die cavity.Positioning and guiding nail and positioning hole that mould is provided with, can be prevented The punching eccentric force that mould is produced in punching.
Preferably, the scrap (bridge) amount for scrap (bridge) being left on the outside of the die cavity is 1mm.
Preferably, the quantity of the positioning and guiding nail and the positioning hole at least respectively has two.
Preferably, the lower mould side wall is provided with airduct and blower fan, and the airduct is connected with blower fan.
Preferably, the lower mould is provided with cover plate.
The beneficial effects of the utility model are:By cancelling the scrap (bridge) between die cavity and die cavity, that is, eliminate workpiece Scrap (bridge) between workpiece, the scrap (bridge) being omitted from is arranged between workpiece and clout side, so will not both increase raw material chi It is very little, also increase the stability of binder, it is ensured that the part of production is qualified.Lower mould side wall is provided with airduct and blower fan, by the zero of generation Broken waste material blows out die cavity, to ensure not influence next process, due to the waste material scrap (bridge) small volume of generation, in lower mould provided with lid Plate prevents waste material from disorderly flying.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and constitutes a part for specification, with this practicality New embodiment is used to explain the utility model together, does not constitute to limitation of the present utility model.In the accompanying drawings:
Fig. 1 is the punching discharge schematic diagram that edge-lapped value is left between prior art part;
Fig. 2 is the punching discharge schematic diagram without edge-lapped value between the utility model part;
Fig. 3 is a kind of structural representation of the die cutting die without scrap (bridge) of the utility model.
Embodiment
The punching discharge schematic diagram left between the part of original technology as shown in Figure 1, when running into the larger original of hardness During material, blanking pressure becomes big, is easily caused the part in the middle of part i.e. scrap (bridge) and is drawn into die cavity 13, in order to avoid such feelings Condition, is not provided between scrap (bridge), the utility model part as shown in Figure 2 the punching row without edge-lapped value between die cavity 13 and die cavity 13 Expect schematic diagram, so add the width of binder, be difficult to be drawn into die cavity 13 this addresses the problem scrap (bridge).
A kind of die cutting die structural representation without scrap (bridge) as shown in Figure 3, the die cutting die without scrap (bridge) includes upper mould Frame 1 and lower mold holder 2, the downside of top mold frame 1 are provided with guide pin bushing 3, and the upside of lower mold holder 2 is provided with and leading that the guide pin bushing 3 matches Post 4, the top mold frame 1 is provided with mould 8, and the lower mold holder 2 is provided with lower mould 9, and the upper mould 8 is provided with positioning and guiding nail 5, institute State lower mould 9 and be provided with the positioning holes 6 that 5 matchings are followed closely with positioning and guiding;The upper mould 8 is provided with cutting knife 7, and the lower mould 9 is provided with some moulds Chamber 13, as shown in Fig. 2 scrap (bridge) is left in the outside of the die cavity 13, without scrap (bridge) between the die cavity 13 and die cavity 13, what mould was provided with Positioning and guiding nail 5 and positioning hole 6, the punching eccentric force that can prevent mould from being produced when being punched part.The outside of die cavity 13 The scrap (bridge) amount for leaving scrap (bridge) is 1mm.
The quantity of the positioning and guiding nail 5 and the positioning hole 6 at least respectively has two.
Part can leave scrappy waste material after being punched, the lower side wall of mould 9 is provided with airduct 10 and blower fan 11, the airduct 10 are connected with blower fan 11, and waste material is blown out lower mould 9 by airduct 10, so as not to influence the progress of next process, due to generation Waste material scrap (bridge) small volume, in order to prevent waste material from disorderly flying, is provided with cover plate 12 on lower mould 9.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, although ginseng The utility model is described in detail according to previous embodiment, for those skilled in the art, it still can be with Technical scheme described in foregoing embodiments is modified, or equivalent substitution is carried out to which part technical characteristic.It is all Within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc. should be included in this practicality Within new protection domain.
