Comprehensive above-mentioned and by reference to the accompanying drawings 5, the below is described in detail the operation principle of the utility model cylinder shaper structure 100, and is as follows:
During moulding, described left and right die 41,42 forms downward open state, described punch 3 is between the described left and right die 41,42, sheet metal 200 is transported between described punch 3 tops and left and right die 41,42 belows, the bead structure of the both sides of described sheet metal 200 for being bonded with each other together.Described driving mechanism 2 drives described push rod 65, described push rod 65 stretches out and then conflicts with the inclined-plane 62a1 of described top die 62, thereby promoting described top die 62 under the effect of inclined-plane 62a1 and under the guiding of described guide rod 61a, moving down along described sliding seat 61, driving simultaneously the described spring 64 of described constrictor 63 compressions; At this moment, described press keeping section 62b moves down and described sheet metal 200 is pressed on the described punch 3 arc surface 3a topmost, described the first groove 62b1 on the described press keeping section 62b squeezes out the cylinder lateral wall identical with described punch 3 arc surface 3a shapes with described sheet metal 200, and it is close to described punch 3 to drive described sheet metal 200 two edges; At this moment, described driving mechanism 2 drives the first connecting rod 51 of a pair of described pushing mechanism 5, described first connecting rod 51 is risen along central axis direction, and promote an end of described swing arm 53, one end of described swing arm 53 upwards rotates, at this moment, the other end of described swing arm 53 rotates, and promote described second connecting rod 52, described second connecting rod 52 moves down along central axis direction, and then promote respectively a described left side by described rotation section 4b, right die 41,42, because a described left side, right die 41,42 are articulated on the described frame 1, therefore by articulated section 4a, a described left side, right die 41,42 rotations and close in opposite directions, and then drive the described punch 3 that described sheet metal 200 coatings mediate, thus the shape of described cylindrical shell formed, and the two edges of described sheet metal 200 fasten mutually.At this moment, described driving mechanism 2 drives described guide pillar 73, make described guide pillar 73 along described guide pin bushing 74 upward slidings, and then by described dip mold 71 risings of described base plate 72 promotions, the second groove 71a of described dip mold 71 compresses the fastening place of described sheet metal 200 two edges, makes the two edges described punch 3 arc surface 3b bottom that fits, thereby forms another and described punch 3 cylinder lateral wall that arc surface 3b shape is identical bottom of described cylindrical shell, at this moment, the complete moulding of described cylindrical shell.At last, described driving mechanism 2 drives described pushing mechanism 5 and dip mold assembly 7 is returned to initial position, described top die 62 is returned to initial position under the restoring force effect of described spring 664, whole cylinder shaper structure 100 is proceeded next time processing and forming again.
Compared with prior art, because the utility model is fixed in described punch 3 on the frame 1, and articulate a described left side in the both sides of described punch 3, right die 41,42, by being articulated in described swing arm 53 on the frame 1 and articulating described first connecting rod 51 and second connecting rod 52 at its two ends, utilize the swing of swing arm 53 and change nyctitropic characteristics, the course of action that makes described driving mechanism 2 promote described first connecting rod 51 risings changes the action that second connecting rod 52 moves down into, thereby make described driving mechanism 2 promote simultaneously a described left side, right die 41,42, a described left side, right die 41,42 just rotate and matched moulds around its articulated section, and then coat described punch 3, the matched moulds process is namely to the extruding of described sheet metal 200, make it form the shape consistent with described punch 3, thereby formation cylindrical shell, whole process only need make driving mechanism 2 carry out a drive actions and can finish the transformation of sheet metal 200 to the cylindrical shell moulding, greatly simplify forming step, moulding is quick, Effective Raise the rate that comes into force.
The structure of the driving mechanism 2 that the utility model cylinder shaper structure 100 is involved and drive principle are well known to those of ordinary skill in the art, no longer are described in detail at this.
Above disclosed only is preferred embodiments of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
