Abstract
A novel blanking die comprises an upper die component and a lower die component. The upper die component comprises an upper die plate and an upper male die. The lower die component comprises a lower die plate and a lower female die with a cavity. The blanking die is characterized in that the cavity of the lower female die is a straight cavity communicating an upper end face and a lower end face. An ejector mechanism is mounted in the cavity and comprises a ejector plate and a plurality of elastic support columns which are mounted between the ejector plate and the lower die plate. The elastic support columns are made of casting polyurethane. The ejector plate is connected with the lower die plate through a plurality of bolts. A gap is reserved between the ejector plate and the inner wall of the cavity. The novel blanking die has the advantages that the cavity of lower female die is of the straight communicating cavity structure, the effective edge length formed by the lower female die is increased as compared with the structure by forming a blanking hole in the existing lower female die, and the repeated service life of the die is prolonged; the ejector mechanism comprising the ejector plate and the elastic support columns made of casting polyurethane, products can be ejected stably from inside the die after punching, and punching stability is increased at the same time.
Description
Technical field
The utility model relates to sheet metal blanking mould, particularly a kind of novel blanking die with material jacking mechanism.
Background technology
At present, the blanking die adopting in iron art furnishings manufacturing process is by upper die component and counterdie module composition.Upper die component consists of cope match-plate pattern and upper male mould, and lower membrane module consists of lower bolster and lower cavity die.Lower cavity die is provided with die cavity, and die cavity consists of the blade connecting up and down and material-dropping hole portion, and the cross-sectional area of material-dropping hole portion is greater than the cross-sectional area of blade, and the intersection, upper surface of blade and lower cavity die forms cutting edge.After cutting edge wearing and tearing, can form by the upper surface of grinding lower cavity die new cutting edge.This mould in use has the following disadvantages:
1, direct die-cut blanking down, die-cut poor stability;
2,, owing to being provided with material-dropping hole in the die cavity of lower cavity die, effective cutting edge that lower cavity die can form is shorter, cause mould to reuse the life-span short.
Summary of the invention
The utility model improves die-cut stability for the technical problem existing in solution known technology provides a kind of, extends the novel blanking die that mould is reused the life-span.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
A kind of novel blanking die, comprise upper die component and lower membrane module, described upper die component consists of cope match-plate pattern and the upper male mould that is fixed on cope match-plate pattern lower end, described lower membrane module consists of lower bolster and the lower cavity die with die cavity that is fixed on lower bolster upper surface, it is characterized in that: the die cavity on lower cavity die is for being communicated with the straight-through chamber of upper and lower end face; Material jacking mechanism is installed in die cavity, described material jacking mechanism comprise die pad and be located at die pad and lower bolster between several elastomeric support column, elastomeric support column is made by excellent power glue material, described die pad is connected with lower bolster by several bolts, between described die pad and the inwall of die cavity, leaves gap.
The technical scheme that the utility model can also be taked is:
The quantity of described elastomeric support column is consistent with the quantity of bolt, and described elastomeric support column is set with and is connected one by one with bolt.
Described gap is 0.2-0.3mm.
Advantage and the good effect that the utlity model has are:
1, in this blanking die, the die cavity of lower cavity die is arranged to straight-through cavity configuration, than the existing structure that material-dropping hole is set on lower cavity die, has extended effective cutting edge length that lower cavity die can form, and then prolongation mould is reused the life-span.
2, the material jacking mechanism that the elastomeric support column that employing is made by die pad and excellent power glue material forms ejects stably after product is die-cut in mould, has also improved die-cut stability simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, upper die component; 11, cope match-plate pattern; 12, upper male mould; 2, lower membrane module; 21, lower bolster; 22, lower cavity die; 221, die cavity; 3, material jacking mechanism; 31, die pad; 32, elastomeric support column; 4, bolt.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of novel blanking die, comprises upper die component 1 and lower membrane module 2.Described upper die component consists of cope match-plate pattern 11 and the upper male mould 12 that is fixed on cope match-plate pattern lower end.Described lower membrane module consists of lower bolster 21 and the lower cavity die with die cavity 221 22 that is fixed on lower bolster upper surface.Die cavity on lower cavity die is for being communicated with the straight-through chamber of upper and lower end face.Material jacking mechanism 3 is installed in die cavity.Described material jacking mechanism comprise die pad 31 and be located at die pad and lower bolster between several elastomeric support column 32, elastomeric support column is made by excellent power glue material.Described die pad is connected with lower bolster by several bolts 4.Concrete, bolt, through lower bolster, is provided with counter sink on lower bolster, and the spiral shell head of bolt is arranged in counter sink, and bolt and die pad are threaded connection.When the spiral shell head of bolt is pressed on the end face of counter sink, the distance between spiral shell head outer face and the lower surface of lower bolster need to be greater than the distance that moves down of in die-cut process die pad.Between described die pad and the inwall of die cavity, leave gap, this gap has guaranteed that die pad is when moving up and down, and does not swipe with the inwall of die cavity.In the utility model, this gap is preferably 0.2-0.3mm.
In said structure, elastomeric support column preferably adopts following syndeton with bolt: the quantity of described elastomeric support column and the quantity of bolt are consistent, and described elastomeric support column is set with and is connected one by one with bolt.This syndeton has facilitated installation and the location of elastomeric support column, makes whole material jacking mechanism compact conformation.
