The specific embodiment
As shown in the figure, a kind of drawing and forming mould of aluminium lid mainly is made up of upper bolster 1, die shoe 2 and driving mechanism; Be connected with die shank 11 in the upper surface of upper bolster 1, die shank 11 is connected with upper bolster 1 through fastening assemblies such as screws, through the 1 up or downward movement of driving mechanisms control upper bolster; Be connected with patrix punch 3 and patrix drift 4 in the lower surface of upper bolster 1, correspondence is provided with counterdie die 5 and presses pier 6 on die shoe 2, and counterdie die 5 is equal with the upper surface of pressing pier 6; Patrix punch 3 is coaxially set with counterdie die 5; Stability after the moulding of assurance bottle cap, patrix drift 4 is coaxially set with pressure pier 6, is used for the crease first time is carried out in the bottle cap upper surface; Patrix punch 3 has the cylindrical core structure; In its cavity, be provided with patrix pusher core 7, the patrix charging ram 8 that is connected with patrix pusher core 7 links to each other with knockout rod 9 after passing upper bolster, in the cavity of patrix pusher core 7, is provided with patrix compression leg 10; The lower surface of patrix compression leg 10 is compared with the lower surface of patrix pusher core 7 and is exposed a small boss slightly, is used for impression is for the second time implemented in the bottle cap upper surface;
Described counterdie die 5 has a cylindrical core structure; In the cavity of counterdie die 5, be provided with the counterdie pusher core 12 of annular; In the cavity of counterdie pusher core 12, be provided with counterdie stretching convex die 13; Counterdie stretching convex die 13 is connected with the end that spring supports 14 bars; The other end of spring supporting bar 14 passes die shoe 2 and links to each other with spring base 15, and the counterdie charging ram 16 that is connected with counterdie pusher core 12 is connected with the counterdie pusher ring 17 that is enclosed within the spring supporting bar outer circumference surface after passing die shoe, on the spring supporting bar outer circumference surface between counterdie pusher ring 17 and the spring base 15, is arranged with spring 18;
Above die shoe 2, also be provided with retainer plate 19; Retainer plate 19 upper surfaces are with counterdie die 5 and press the upper surface of pier 6 all equal; Between patrix punch 3 and retainer plate 19, be provided with stripper 20; The plate face of described stripper 20 is provided with circular hole, and circular hole and counterdie die 5 are coaxially set, and the size in circular hole aperture equates with the pore size of counterdie die 5.
Described counterdie stretching convex die 13 upper surfaces are provided with circular groove, and circular groove and patrix compression leg 10 are coaxially set.
The concrete operations of the utility model are following:
The first step at first: the aluminium strip 21 that will be cut is placed between retainer plate 19 and the stripper 20 in advance; It is descending that driving mechanism drives upper bolster 1; Patrix drift 4 withstands aluminium strip and is pressed in aluminium strip above the pier 6; Make the aluminium strip surface pit occur, whole up the returning of upper bolster accomplished impression for the first time then;
Second step: the then aluminium strip station that moves forward, require station of the every motion of aluminium strip must be accurately, guarantee that the center of impression and the second step blanking of the first step must be consistent; Back upper bolster 1 is whole more descending; Patrix punch 3 passes the circular hole of stripper being pressed in above the counterdie die 5 by the aluminium strip of stamping-out, and patrix punch 3 continues to fall, and compresses into counterdie die hole to the aluminium strip that is crushed under the patrix punch; Make that aluminium strip separates on the aluminium strip of compressing into counterdie die hole and the retainer plate, accomplish blanking;
The 3rd step: driving mechanism continues be with upper bolster 1 descending; Patrix punch 3 heads on the aluminium sheet edge of being pressed to be continued to fall; It is whole descending to force counterdie pusher core 12 to head on counterdie charging ram 16, counterdie pusher ring 17, and spring 18 is compressed, and this moment relatively counterdie stretching convex die 13 head on the aluminium sheet centre of being pressed to up; Promote patrix pusher core 7, patrix charging ram 8, knockout rod 9 to up; And, circular thin aluminum sheet is become towards the tubular (aluminium lid) in sky by in aluminium sheet centre jacking patrix punch 3 holes of pressing, accomplish stretching;
The 4th step: upper bolster 1 continues descending, and counterdie stretching convex die 13 heads on the aluminium sheet central part of being pressed and continues relatively to make patrix compression leg 10 lower surfaces head on the aluminium sheet central part of being pressed to up.Final patrix compression leg is in the circular groove of the lower surface aluminium sheet jacking counterdie stretching convex die of being withstood 13, and this has just accomplished secondary impression.
The 5th step: driving mechanisms control upper bolster 1 returns; Patrix punch 3 is up, and the aluminium strip that is enclosed within the patrix punch is simultaneously taken off by stripper, and counterdie die 5 inner assemblies are kept in the center under the effect of spring; When the patrix punch is up to certain altitude; Knockout rod is pushed, and knockout rod promotion patrix charging ram, patrix pusher core are released aluminium lid from the hole of patrix punch, and bottle cap drops on and sees completion on the stripper off.This mould only need be realized impression for the first time; The overall process of the impression more than in punching course, when the whole whereabouts of patrix once, just having accomplished afterwards, blanking, stretching, secondary impression; One-shot forming makes that the integrality of bottle cap is better, and has improved the production efficiency of enterprise greatly.
