Description
Technical field
The present invention relates to cold punching technology, relate in particular to a kind of structure of the bullion sheet material sawing sheet for the production of circular stamping.
Background technique
Stamping process is generally used for production in enormous quantities, and for saving resource, reduce costs, the utilization ratio that improves sheet material seems especially important.While producing circular stamping, be first rolling or the sheet metal that becomes are cut into bar shaped blank, then carry out punch process, circle shape Red part bar shaped sheet material sawing sheet is that Red presses the semifinished product in producing.As shown in Figure 1, its stock utilization is probably 70% to general round shape Red part bar shaped sheet material sawing sheet structure.The shortcoming of this bar shaped sheet material sawing sheet structure is, its long limit is all straight flange, and the material at edge, the long limit of stripe board shape sawing sheet structure is not fully utilized, and stock utilization is not ideal enough.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of material that can make full use of edge, the long limit of bar shaped sheet material sawing sheet structure, and stock utilization can be higher than 80% circular stamping bar shaped sheet material sawing sheet structure.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is, a kind of circular stamping bar shaped sheet material sawing sheet structure, the length of sawing sheet is obviously greater than the width of sawing sheet, sawing sheet comprises the long limit of at least one bending, the diameter and the punching press surplus sum that define circular stamping are spacing, the upper base that described long limit is isosceles trapezoid and the orderly extension of two waists, and the length of sawing sheet equals the radius of the integral multiple of described spacing, a circular stamping, three's sum of a punching press surplus; The width of sawing sheet equals 1.5～1.9 extraordinarily punching press surpluses of described spacing.
Above-described circular stamping bar shaped sheet material sawing sheet structure, the height of described isosceles trapezoid is described spacing and punching press surplus sum 0.11～0.15 times, the wave peak width on described long limit equals the width of trough, and the base angle of described isosceles trapezoid is 29 ° to 31 °.
Above-described circular stamping bar shaped sheet material sawing sheet structure, sawing sheet comprises the long limit of two bendings, two crests of growing limits are along the length direction of sawing sheet 1/2nd spacing that stagger.
Above-described circular stamping bar shaped sheet material sawing sheet structure, sawing sheet minor face is stepped shaft, and described ladder comprises two straight flanges vertical with sawing sheet length direction, and with the hypotenuse that is connected two straight flanges, intersect the mid point of described hypotenuse and the medial axis of sawing sheet; The degree of depth of ladder equals the spacing described in 1/2nd, and the direction of sawing sheet two minor face ladders is identical.The angle of described hypotenuse and sawing sheet medial axis is 27 ° to 31 °.
Above-described circular stamping bar shaped sheet material sawing sheet structure, described punching press surplus is 1 to 5 millimeter.
The long limit of the circular stamping bar shaped of the present invention sheet material sawing sheet adopts curved shape, can make full use of the material at edge, the long limit of bar shaped sheet material sawing sheet, makes the utilization ratio of material surpass 80%, the object that realized saving resource, further reduces costs.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Figure l is the outline drawing that prior art passes system circle shape Red part bar shaped sheet material sawing sheet structure.
Fig. 2 is the circular stamping bar shaped of the present invention sheet material sawing sheet constructed embodiment outline drawing.
Fig. 3 is the circular stamping bar shaped of embodiment of the present invention sheet material sawing sheet structure marker map.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
As shown in Figure 2, the thickness of sawing sheet is between 0.1 to 5 millimeter for the shape of the circular stamping bar shaped of the present invention sheet material sawing sheet constructed embodiment, and the diameter D and the punching press surplus m sum that define circular stamping are spacing T.
The length L round number of sawing sheet is doubly to the width W of sawing sheet, and sawing sheet has two to be curved shape in two long limits, and two corrugated crests in long limit are along the length direction of sawing sheet 1/2nd the spacing T that staggers; Extending in order with-determining deviation T of the upper base that long limit is isosceles trapezoid and two waists, the total length L of sawing sheet equals the radius R of integral multiple spacing T, circular stamping, three's sum of a punching press surplus m.
The width W of sawing sheet equals 1.5～1.9 times of spacing T, and (the best is that 1.87 times of) Jia Red press surplus m.Grow the isosceles trapezoid that is shaped as on limit, the height of isosceles trapezoid is 0.11～0.15 times (the best is 0.13) times of spacing T and punching press surplus m sum, and the wave peak width Nl of wave equals the width N2 of trough, and the base angle of isosceles trapezoid is 31 °.Because stagger during discharge during punching press, so the profile of sawing sheet also will stagger along its length.
The minor face of sawing sheet is stepped shaft, and the direction of cutting the minor face ladder of expecting two of left and right is identical.Each ladder has two straight flanges vertical with sawing sheet length direction, and with the hypotenuse that is connected two straight flanges, intersect the mid point of hypotenuse and the medial axis of sawing sheet, and the angle of cut P of hypotenuse and sawing sheet medial axis is 29 °.The degree of depth h of ladder equals 1/2nd spacing T.
In above-described circular stamping bar shaped sheet material sawing sheet embodiment, punching press surplus m is 1 to 5 millimeter, and the most frequently used punching press surplus m is between 1 to 3.
As shown in Figure 3, in the middle of sawing sheet comes, two long limits are all rippled edges to the circular stamping bar shaped of the present invention sheet material sawing sheet embodiment's marker method.According to this marker method, can make full use of the material at edge, the long limit of bar shaped sheet material sawing sheet, make the utilization ratio of material reach 86%, the object that realized saving resource, further reduces costs.
Although described by reference to the accompanying drawings working of an invention mode; but the patent owner can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of the claim of invention, all should be within the protection domain of invention.
