Abstract
The invention relates to an adjustable fast-replacement type gold grain punching die. The die is composed of an upper die with a punching blade and a lower die with an adjustable limiting device and a punching bottom base. The punching blade is in clearance fit with a blade fixing plate and is compressed through a screw, and fast placement can be achieved. A semicircular groove opening is formed in the cutting edge of the blade and is identical to gold grains in radius. The limiting device is composed of a limiting block, a belleville spring and an adjusting screw plug, and the limiting position can be adjusted by rotating the screw plug. The punching bottom die is in clearance fit with a bottom die fixing plate and is assembled to the bottom die fixing plate through the belleville spring and an adjusting screw sleeve, the clearance between the cutting edge of the bottom die and the blade can be adjusted by rotating the screw sleeve, and meanwhile fast replacement can also be achieved. A through hole is formed in the bottom die, and the hole diameter of the cutting edge is identical to the diameter of the gold grains. The end faces of the gold grains can be free of deformation and burrs, and efficient precise punching with the consistent weight of a single grain can be achieved.
Description
Technical field
Patent of the present invention relates to a kind of adjustable quick-changing type goldc grains die cutting die, belongs to the forming materials technical field of process engineering.
Background technology
The present invention proposes mainly for the manufacture of current domestic evaporated gold particle.Implement the front modes that adopt common punching and lathe cut of this technology more.Common punching is being difficulty aspect gap adjustment, spacing and member replacing, and cost is higher, and product burr is many, step on angle, poor dimensional precision, and the homogeneity of simple grain weight is difficult to control.Use lathe cut, production efficiency is extremely low, and still has a small amount of burr.
Summary of the invention
The technical problem to be solved in the present invention is the manufacture of evaporated gold particle for current chip back of the body gold.Before technological innovation, the manufacture of evaporated gold particle exist burr many, step on angle, poor dimensional precision, the unequal defect of simple grain weight, in quality and production efficiency, cannot comprehensively be improved, can not form volume shipment.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of adjustable quick-changing type goldc grains die cutting die, comprises upper die and lower die; Described patrix is provided with die-cut blade, and cutting edge place, die-cut blade bottom establishes semicircular notch; Described counterdie comprises bed die fixed head and die-cut bed die, and bed die fixed head is provided with hole punching, and die-cut blade can be along hole punching knee-action; Die-cut bed die is established through hole vertically, the vertical hole punching setting of this through hole and being communicated with hole punching; Aforementioned through-hole diameter, notch diameter are all consistent with evaporated gold particle diameter.
The present invention establishes semicircular notch at cutting edge place, die-cut blade bottom, and radius is consistent with the radius of evaporated gold particle; At die-cut bed die center, establish through hole, aperture is consistent with the diameter of evaporated gold particle; This set makes spun gold material stretch in hole punching by the through hole on die-cut bed die, and when die-cut blade is descending, spun gold material cylindrical can be fitted with its semicircular notch.In the time of guaranteeing that in die-cut process, circular wire material is subject to shear pressure like this, incision position material is obstructed because of the Radial Flow that plastic deformation produces, and makes evaporated gold particle two ends can not produce moulding distortion because being subject to the extruding of cutting force.
For guaranteeing that when die-cut, evaporated gold particle two ends are without burr, a side of described bed die fixed head is provided with the shoulder type through hole vertical with hole punching, and the outside of shoulder type through hole is screwed hole, and inner side is unthreaded hole, and unthreaded hole is communicated with hole punching; Described die-cut bed die agrees with and is placed in shoulder type through hole, and coordinates with this shoulder type via clearance, and shoulder is established at die-cut bed die cylindrical middle part, props up the sidewall of screwed hole and unthreaded hole junction after shoulder one side socket butterfly spring, and shoulder opposite side is socketed Adjusting bolt Adjusting screw.The setting of turn swivel nut, plays the effect of the blade clearance of the die-cut blade of capable of regulating and die-cut bed die.In die-cut process, owing to there is gap between die-cut blade and die-cut bed die, the material initial stage is plastic deformation, and rear generation fracture causes burr; And when the blade clearance between die-cut blade and die-cut bed die is zero substantially, can delay early producing of crackle, and reduce fracture belt, realize relatively die-cut without burr.In addition, die-cut bed die coordinates with shoulder type via clearance, and while this gap length being arranged in the accuracy rating of technological requirement, the quick-detachment of being both convenient to after die-cut bed die wearing and tearing is changed, and also can guarantee location.
For guaranteeing when die-cut, the blanking precision of evaporated gold particle and the uniformity of simple grain weight, the another side of described bed die fixed head is also provided with shoulder type through hole, and the outside of shoulder type through hole is screwed hole, and inner side is unthreaded hole, and unthreaded hole is communicated with hole punching; Described limited block agrees with and is placed in shoulder type through hole, described limited block and bed die fixed head unthreaded hole matched in clearance, shoulder is established in limited block end, props up the sidewall of screwed hole and unthreaded hole junction after shoulder one side socket butterfly spring, and the crimping of shoulder opposite side regulates plug screw.Although the basic size of evaporated gold is identical, the silk material diameter of different batches has the minor variations of tolerance aspect, and material has difference (density changes), consistent for guaranteeing the evaporated gold particle weight obtaining, and therefore needs trace to regulate.Arrange after adjustable limited block, during every batch of die-cut spun gold material, first trial cut, detection, adjusting limited block, work continuously after meeting the demands again.
For guaranteeing in mould use procedure, the quick-replaceable after punching cutter pad wear, described patrix also comprises blade fixed head, and blade fixed head arranges card discharge hole vertically, and tapped through hole is established in both sides; Described die-cut blade top is provided with corresponding installing hole, and diameter is less than screwed hole diameter; Card discharge hole is inserted on die-cut blade top, and screw supports into installing hole by both sides screwed hole, and die-cut blade and patrix are fixed.
Advantage of the present invention is: easy to operate, production efficiency is high; The evaporated gold particle of processing without stepping on angle, without burr, dimensional accuracy is high, simple grain weight is easy to control, weight high conformity; In process, actual operation cost is low.
