Abstract
The utility model provides a redrawing composite die for a double action punch, which comprises a lower template and a fixed plate. A lower blanking male die, a rubber blanket,a secondary swaging ring and a discharger pressed by a spring are arranged in the lower template; an upper blanking female die, an adjusting nut, an adjusting screw rod and a post rod are arranged on the fixed plate; one end of the post rod is provided with a spring, and the other end of the post rod is provided with a secondary mandril and a cutting ring; the secondary swaging ring is arranged in the lower blanking male die; the discharger is arranged in the secondary swaging ring; a first swaging ring is arranged in the upper blanking female die; a first mandril is arranged in the first swaging ring; a spring is arranged between the adjusting screw rod and an inner hole of the fixed plate; and a spring is arranged between the first swaging ring and the first mandril. The redrawing composite die for the double action punch finishes four motions, namely blanking, a first drawing, redrawing and cutting through a set of die. If a bottle cap needs to be drawn twice for shaping, the redrawing composite die for the double action punch can shape the bottle cap, so as to improve the productivity greatly and reduce the production cost.
Description
Technical field
The utility model belongs to mechanical field, relates in particular to a kind of secondary deep-drawing composite mold.
Background technology
At mechanical processing industry, particularly the moulding of aluminium matter bottle lid generally will be through pull and stretch repeatedly, and it mainly is subjected to the restriction of two aspects, the one, drawing coefficient, the 2nd, press machine.If carry out compound pull and stretch, because the continuous increase of pressure, it is damaged that product is occurred on common punch press, so general each once drawing that carries out needs many molds just can finish moulding, and the expense height, efficient is also low.
Summary of the invention
The utility model provides a kind of secondary deep-drawing composite mold at two ejector half stamping machines, and the moulding that has solved conventional aluminum matter bottle cap generally will need many molds just can finish moulding, expense height, inefficient shortcoming through pull and stretch repeatedly.
The technical solution of the utility model is achieved in that a kind of secondary deep-drawing composite mold, constitute by lower bolster, fixed head, be equipped with down blanking punch, rubber blanket, secondary binder ring in the lower bolster and by the discharger of spring compression, be equipped with blanking die on the fixed head, adjust nut, adjust screw rod and push rod, push rod one end has spring, the other end has secondary fuse and blank ring, establish secondary binder ring in the following blanking punch, establish discharger in the secondary binder ring, establish the binder ring in the last blanking die one time, establish one time fuse in the binder ring;
Adjust between screw rod and the fixed head endoporus and be provided with spring, be provided with spring between a binder ring and a fuse.
The beneficial effects of the utility model are: it is that blanking, once drawing, secondary deep-drawing, four actions of blank are finished with a mold.If bottle cap needs twice drawing and forming, get final product drawing and forming by this mould, heightened productivity ratio greatly, reduced production cost.
Description of drawings
Fig. 1 is a generalized section of the present utility model.
Part explanation: 1, blanking punch down, 2, rubber blanket, 3, secondary binder ring, 4, discharger, 5, go up blanking die, 6, binder rings, 7, once drawing fuse, 8, adjusting lever, 9, adjust nut, 10, push rod, 11, fixed head, 12, blank ring, 13, the secondary deep-drawing fuse, 14, lower bolster.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: a kind of secondary deep-drawing composite mold, comprise lower bolster 14 and fixed head 11, be equipped with down blanking punch 1 and rubber blanket 2 in the lower bolster 14, secondary binder ring 3 is established in rubber blanket 2 upper ends, establish discharger 4 in the secondary binder ring 3 by spring compression, be equipped with adjustment nut 9, adjusting lever 8 and the push rod 10 of blanking die 5, adjustable pressure on the fixed head 11, push rod 10 1 ends have spring, the other end has secondary fuse 13, blank ring 12, establish in the last blanking die 5 in 6, binder rings 6 of a binder ring and establish fuse 7 one time.
It is up that lower bolster 14 drives whole compound die bottom, and following blanking punch 1 compresses a blanking action that binder ring 6 is finished material.Continue in the up process at lower bolster 14, it is up that following blanking punch 1 promotes a binder ring 6, and one time fuse 7 promotes secondary binder ring 3 descending being pressed on the rubber blanket 2, finishes the once drawing and forming action, and lower bolster 14 stops up action.During once drawing and forming, can adjust the once drawing pressure-pad-force, can adjust pressure-pad-force when controlling secondary deep-drawing threaded adjusting lever 8 by adjusting nut 9 compression springs.
After once drawing and forming was intact, cope match-plate pattern roof pressure push rod 10 was descending, and push rod 10 drive blank rings 12 and post forming fuse 13 are descending, and it is descending that post forming fuse 13 promotes dischargers 4, finishes secondary deep-drawing moulding action.The arc surface of extruding secondary binder ring 3 was finished the blank action when blank ring 12 was descending; Whole bottle cap drawing and forming action finishes.
And then the whole compound die of lower bolster 14 drives bottom is descending, cope match-plate pattern is up simultaneously, push rod 10 drives horizontal reset on blank ring 12 and the post forming fuse 13 under spring action, in the middle of this process, secondary binder ring 3 and discharger 4 reset under the effect of spring, and eject material flanging ring, pull and stretch finished product lid respectively, and the finished product lid is also deviate from from post forming fuse 13 under the effect of air pressure, and so far whole bottle cap punching press action is finished.
