Abstract
The utility model discloses a punching shear die for foil-shaped brazing filler metal rings, which comprises an upper die and a lower die. The upper die comprises an upper die plate and an annular groove arranged on the upper die plate, a high-elasticity rubber ring is arranged in the groove, and the thickness of the high-elasticity rubber ring is larger than the width of the groove. The lower die comprises a base plate and an annular punching tool arranged on the base plate, the position of the annular punching tool corresponds to that of the high-elasticity rubber ring on the upper die plate, the diameter of an inner ring of the annular punching tool is larger than that of an inner ring of the annular groove on the upper die plate, the diameter of an outer ring of the annular punching tool is smaller than that of an outer ring of the annular groove on the upper die plate, the lower die plate in surface contact with the upper die plate is integrally connected with the base plate through a connecting bolt sunk in the base plate, an elastic rubber pad is arranged between the lower die plate and the base plate, the lower die plate is higher than the annular punching tool, and positioning holes are correspondingly arranged at the centers of the upper die plate and the lower die plate. The punching shear die has the advantages of simple structure, low manufacturing cost, long service life, and fine evenness and high surface smoothness of punched metal foil rings.
Description
Technical field
The utility model relates to mould, especially relates to the foil-shaped brazing material annulus punching and shearing die of a kind of thickness less than 0.05mm.
Background technology
In the prior art; Dashing of the metal tape of general thickness, plate encircles the mould comparative maturity; The punching and shearing die that tradition the is used fit clearance between the stamping knife up and down is to treat the 8%-40% of punching sheet metal thickness, and for the metal forming of punching thickness less than 0.05mm, the gap of stamping knife is in the scope of 0.004mm-0.02mm about requiring; Such required precision is difficult to reach, and the mould cost is high; But mould up and down the gap between the stamping knife will occur greatly punching constantly or mould problem such as block; Especially thickness is less than increasingly extensive amorphous filler metal paper tinsel and the rolling solder paper tinsel of application in the solder industry of 0.03mm, and punching problem continuous and that mould blocks is more serious.
Summary of the invention
The purpose of the utility model is to provide a kind of simple in structure, low cost of manufacture, foil-shaped brazing material annulus punching and shearing die that the punching precision is high.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described foil-shaped brazing material annulus of the utility model punching and shearing die; Comprise patrix and the counterdie that is complementary with it; Said patrix is made up of cope match-plate pattern and the annular groove that is opened on the said cope match-plate pattern; In said groove, be provided with the high elastic rubber circle, the thickness of said high elastic rubber circle is higher than the degree of depth of said groove; Said counterdie comprises substrate and is arranged on the annular stamping knife on the said substrate; Said annular stamping knife is corresponding with the high elastic rubber circle position on the cope match-plate pattern; The interior ring diameter of said annular stamping knife is bigger than the interior ring diameter of cope match-plate pattern annular groove, and the outer ring diameter of said annular stamping knife is littler than the outer ring diameter of cope match-plate pattern annular groove; The lower bolster that contacts with the cope match-plate pattern face is connected as a single entity through connecting bolt and the said substrate that is sunken in the substrate, between lower bolster and substrate, is provided with the elastic rubber pad, and the position of said lower bolster is higher than annular stamping knife.
The center position correspondence of said cope match-plate pattern and lower bolster offers locating hole.
The upper surface of said lower bolster is a matsurface.
The advantage of the utility model is simple in structure, low cost of manufacture, and long service life, the metal forming annulus good planeness of punching out, surface smoothness is high.According to the low characteristics of solder paper tinsel intensity, behind mold cramping solder paper tinsel up and down, utilize the stamping knife in the counterdie that the solder paper tinsel is carried out the hilted broadsword punching.Compare with traditional double-pole punching, the life-span of stamping knife significantly increases the situation that the while can not occur causes mould to block because accompany the solder paper tinsel between the stamping knife up and down.The high elastic rubber circle of patrix cooperates with the stamping knife of counterdie when punching simultaneously; The steel phantom plate that the steel phantom plate of patrix and counterdie are lined with the elastic rubber pad cooperates; The very stiff and demanding situation of member can not appear in this soft or hard fit system between the mould up and down, and die life significantly prolongs; In addition because the up and down large scale gap of mould soft or hard cooperation down; Installation accuracy to upper and lower mould requires lower; Need not assemble die holder, the requirement on machining accuracy to other mould accessories except that cutting knife is also lower simultaneously, and therefore manufacturing and maintenance cost significantly reduce.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The described foil-shaped brazing material annulus of the utility model punching and shearing die; Comprise patrix and the counterdie that is complementary with it; Said patrix is made up of cope match-plate pattern 1 and the annular groove that is opened on the cope match-plate pattern 1, and in groove, glueing joint has high elastic rubber circle 2, the thickness of high elastic rubber circle 2 to be higher than the about 1mm of the degree of depth of groove; Counterdie comprises substrate 3 and is connected in the annular stamping knife 4 on the substrate 3; The position of the high elastic rubber circle 2 on annular stamping knife 4 and the cope match-plate pattern 1 is corresponding; The interior ring diameter of annular stamping knife 4 is than the big 3mm of interior ring diameter of cope match-plate pattern annular groove, and the outer ring diameter of annular stamping knife 4 is than the little 3mm of outer ring diameter of cope match-plate pattern annular groove; Be connected as a single entity with substrate 3 through the connecting bolt 6 that is sunken in the substrate 3 with 1 lower bolster that contacts 5 of cope match-plate pattern; Between lower bolster 5 and substrate 3, be provided with elastic rubber pad 7; The position of lower bolster 5 is higher than annular stamping knife 4 about 2mm; So under pressure, lower bolster 5 can move up and down together with connecting bolt 6.Center position correspondence at cope match-plate pattern 1 and lower bolster 5 offers locating hole, and can making things convenient for up and down through alignment pin 8, the mould calibration aligns.The upper surface of lower bolster 5 is a matsurface, can increase the frictional force of template surface.
When dashing the ring operation, the die shank 9 of patrix is fixed on the movable ram of punch press, the substrate 3 of counterdie is fixed on the punch press workbench, through alignment pin 8 the upper and lower mould calibration is aligned; The stroke of adjustment punch press makes patrix compress lower bolster 5 at the stroke lowest part and moves down about 3mm.
During punching press, earlier the solder paper tinsel is placed between the upper and lower mould, under punch press drives; Patrix moves down with solder paper tinsel and lower bolster and contacts, and when patrix further moved down, cope match-plate pattern 1 compresses the solder paper tinsel with high elastic rubber circle 2 and lower bolster 5 moves down; Compress elastic rubber pad 7 and make it distortion, under the elastic force effect of elastic rubber pad 7 and high elastic rubber circle 2, the solder paper tinsel firmly is clamped between the upper and lower mould; When lower bolster 5 amounts of moving down are above above 2mm; Stamping knife 4 offset solder paper tinsels along stamping knife 4 inside and outside cutting edge punching fractures, obtain the solder annulus measure-alike with stamping knife with the solder paper tinsel.
