Abstract
The utility model relates to a kind of reciprocating lever blanking die master mold, comprises die shoe, lower bolster, die holder, die, stripper, spring guide, discharging spring and lead; The upper surface of described die is lower than the upper surface 3mm of stripper, and such design makes blanking pressure stepping action on die, and the functional contact stress that such die bears is lower, effectively improves the service life of die.When reciprocating lever blanking die compact conformation described in the utility model, work, automation efficiency is high, processing precision of products is high, discharging is effective, and long service life.
Description
Technical field
The utility model relates to a kind of reciprocating lever part forming mould structure, refers in particular to a kind of blanking die mould master mold of long working life.
Background technology
Reciprocating lever as the vital part of sawing class instrument, its accuracy of manufacture require very high, the maximum feature of reciprocating lever punch process is exactly that material is thick, and the strength of materials is high, shearing area and shear dimension precision requirement high.High-precision blanking processing scheme conventional at present has compound die punch press process, and belong to and once go out all sheared edges, the part defect therefore processed is few, and dimensional accuracy is high, and blanking pressure is relative also less.But the reciprocating lever of machining high-precision, can the key of compound die punch press process be adopted to be exactly the working life how ensureing concave-convex mold, be therefore necessary to research and develop a kind of blanking die master mold for processing reciprocating lever, key will reduce concave-convex mold working stress exactly.
Utility model content
The utility model object is the blanking die master mold providing a kind of long working life for processing reciprocating lever in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of reciprocating lever blanking die master mold, and described master mold comprises die shoe, lower bolster, die holder, die, stripper, spring guide, discharging spring and lead; Described lead is fixedly connected on die shoe; Described die holder is fixedly connected on die shoe by securing member; Described die is fixed by die holder; Lower bolster is provided with between described die and die shoe; Described die periphery is arranged with stripper; The lower end of described stripper is fixedly connected with spring guide; Described spring guide is provided with discharging spring; The upper surface of described die is lower than the upper surface 3mm of stripper.
Preferably, described lead has four, is separately positioned on the corner of die shoe.
Preferably, the end of described discharging spring is provided with plug screw.
Preferably, the upper end of described die shoe is also provided with limited post, and described limited post is fixedly connected with die shoe by screw.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The reciprocating lever blanking die master mold of the utility model scheme, automation efficiency is high, processing precision of products is high, discharging is effective, for reducing die working stress, design the upper surface 3mm of upper surface lower than stripper of die, make blanking pressure stepping action on die, the functional contact stress that die is born is lower, effectively improves the service life of die, thus reaches unitary mould and increase the service life.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Reciprocating lever blanking die master structure of the present utility model as shown in Figure 1, comprises die shoe 1, lower bolster 2, die holder 3, die 4, stripper 5, spring guide 6, discharging spring 7 and lead 8; Described die holder 3 is fixedly connected on die shoe 1 by securing member; Described die 4 is fixed by die holder 3; Lower bolster 2 is provided with between described die 4 and die shoe 1; Described die 4 periphery is arranged with stripper 5; The lower end of described stripper 5 is fixedly connected with spring guide 6; Described spring guide 6 is provided with discharging spring 7; The upper surface of described die 4 is lower than the upper surface 3mm of stripper 5.Such design, can make blanking pressure stepping action on die, effectively reduces the functional contact stress that die bears.
Further instruction, described lead 8 has four, is separately positioned on the corner of die shoe 1, plays accurate guide effect, to guarantee the accuracy of workpiece.
Further instruction, the end of described discharging spring 7 is provided with plug screw 19.The impulse stroke that Dies ' Blanking adds stripper in man-hour is 6-7mm, and for guaranteeing service life and reliability, therefore adopt the discharging of heavy load Rectangular Spring, stripping force can regulate pre compressed magnitude by plug screw 19.
Further instruction, the upper end of described die shoe 1 is provided with limited post 20, and described limited post 20 is fixedly connected with die shoe 1 by screw.Described spacing 20 move down extreme position for what limit punch, effectively reduce the wearing and tearing of punch and die, can extend punch and die service life.
Accompanying drawing 2 is reciprocating lever blanking die master mold of the present utility model structural representation when coordinating with male model, and described male model comprises upper bolster 9, upper padding plate 10, punch holder 11, punch 12, die pad 13, die pad holder 14, knockout plate 15, push rod 16, spring 17, knockout rod 18 and lead pedestal 21; Described upper bolster 9 is connected by guidance set with between die shoe 1; Described guidance set is exactly the lead 8 on master mold and the lead pedestal 21 on male model, and the lead 8 on described master mold is arranged in the lead pedestal 21 on male model, plays the guide effect of whole mould.
The reciprocating lever blanking die of the utility model scheme, automation efficiency is high, processing precision of products is high, discharging is effective, reduces the functional contact stress that die bears lower, effectively improves the service life of die, thus reaches unitary mould and increase the service life.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
