Abstract
The invention relates to an opening closing mould of a pressure equalizing barrel, and relates to an opening closing mould of an inward flanging of a barrel opening of a pressure equalizing barrel made of aluminum alloy material. The opening closing mould is characterized by simple structure and low cost, and comprises an upper mould and a lower mould, wherein the lower mould comprises a mould cavity which is identical to the surface outline of a barrel body on the lower part of the pressure equalizing barrel; the bottom surface of the upper mould is provided with a spherical-crown groove; and the maximal diameter of the notch of the spherical-crown groove is larger than the diameter of the barrel opening of the pressure equalizing barrel. According to the opening closing mould provided by the invention, material characteristics is combined; a mould pressing proposal using a stamping one-time forming method is disclosed; because the aluminum material has preferable plastic deforming capacity correspondingly to a cold board and a hot board, a smooth opening closing structure can be stamped for one time on a condition that the shape of the upper mould is suitable; situations such as draping, cracking and the like cannot be happened; and the opening closing mould is characterized by high mould efficiency, precise size, low cost and smooth appearance of a finished product.
Description
Technical field
The present invention relates to a kind of punch-forming mold, relate in particular to nozzle in-flanges closing-in mould the equal pressure cylinder of aluminum alloy material.
Background technology
The equal pressure cylinder of annular is roughly tire shape.Added man-hour in small lot batch manufacture, generally be the cylindrical shell that adopts straight mouthful of spinning or the moulding processing of drawing die elder generation in the past, adopts the processing of closing up of artificial spinning means again.The problem that exists is: 1. amount is few high as making the spinning block cost.2. low through manual closing in efficient, and appearance is very rough.
Summary of the invention
The present invention is directed to above problem, a kind of closing-in mould of equal pressure cylinder simple in structure, with low cost is provided.
Technical scheme of the present invention is: comprise upper die and lower die; Said counterdie has and the equal consistent die cavity of pressure cylinder bottom stack shell surface profile; The bottom surface of said patrix is provided with spherical groove, and the maximum gauge of said spherical groove notch is greater than the diameter of said equal pressure cylinder nozzle.
Said equal pressure cylinder stack shell radius is 1 with the ratio of the spherical crown radius of spherical groove: 1.3-1.5.
The present invention combines the material characteristic; The one-time formed mold pressing scheme of employing punching press has been proposed, because aluminum alloy material has better plastic deformation ability with respect to cold drawing, hot plate, therefore; Under the suitable situation of patrix shape, can suppress level and smooth closing in structure once; And situation such as gauffer, cracking can not appear.Mould efficient of the present invention is high, size is accurate, low, the manufactured goods smooth in appearance of cost.
Description of drawings
Fig. 1 is a structural representation of the present invention
1 is patrix among the figure, the 10th, and groove, the 2nd, counterdie, the 20th, die cavity, the 3rd, equal pressure cylinder;
Fig. 2 is a user mode reference diagram of the present invention
31 is closing in structures among the figure.
The specific embodiment
The present invention is as shown in Figure 1; Comprise patrix 1 and counterdie 2; Said counterdie 2 has and the equal consistent die cavity 20 of pressure cylinder 3 bottom stack shell surface profiles, and the bottom surface of said patrix 1 is provided with spherical groove 10, and the maximum gauge of said spherical groove 10 notches is greater than the diameter of said equal pressure cylinder 3 nozzles.
Said equal pressure cylinder 3 stack shell radiuses are 1 with the ratio of the spherical crown radius of spherical groove 10: 1.3-1.5.
User mode of the present invention is as shown in Figure 2, and patrix 1 supply port utilizes the closing in of contracting in the nozzle of curved surface with equal pressure cylinder 3 of spherical groove 10, finally forms closing in structure 31.
Claims (2)
1. the closing-in mould of an equal pressure cylinder; Comprise upper die and lower die; Said counterdie has and the equal consistent die cavity of pressure cylinder bottom stack shell surface profile; It is characterized in that the bottom surface of said patrix is provided with spherical groove, and the maximum gauge of said spherical groove notch is greater than the diameter of said equal pressure cylinder nozzle.
2. the closing-in mould of a kind of equal pressure cylinder according to claim 1 is characterized in that, said equal pressure cylinder stack shell radius is 1 with the ratio of the spherical crown radius of spherical groove: 1.3-1.5.
