When the first rotary table 7 rotates, the first arc-shaped plate 6 is driven to rotate through the sliding fit action of the first sliding block 8 and the first arc-shaped groove 9, so that the first swing rod 4 is driven to rotate along the axis of the first rotating shaft 5, the first connecting rod 12 and the lifting block 13 are driven to move downwards, then the lifting block 13 drives the stamping column 14 at the bottom end to move downwards, then the stamping part to be stamped in the placing groove 34 is stamped through the arc surface at the bottom end of the stamping column 14, a basin-shaped cavity is formed, and then when the first sliding block 8 rotates to the part coinciding with the arc-shaped track of the first arc-shaped groove 9, at the moment, the first sliding block 8 slides along the inner wall of the first arc-shaped groove 9, but at the moment, the first swing rod 4 swings to the lowest position, and the stop state is kept.

When the punching column 14 moves downwards, the cylinder 15 and the structure mounted thereon are driven to move downwards together, meanwhile, due to the matching action of the limit block 18 and the limit groove 16, the limit block 18 slides in the vertical groove on the limit groove 16, when the electromagnet press plate 27 is firstly contacted with the workpiece to be punched, the electromagnet press plate 27 can push against the telescopic rod 28 to slide in the mounting hole 32 along with the movement of the cylinder 15, the spring 33 is compressed, the effect of prepressing can be achieved through the elastic action of the spring 33, the workpiece to be punched when the punching column 14 punches the workpiece can be prevented from deviating, thereby improving the precision of the punching column 14 when the punching column 14 punches, when the punching column 14 punches the workpiece to be punched downwards, the limit block 18 also moves to the tail end of the vertical groove of the limit groove 16, and contacts with the inclined plane of the elastic wedge 36 and pushes against the elastic wedge 36 to retract, thereby enabling the limit block 18 to cross the elastic wedge 36, and contact with one of them touch switch 37, then can start electromagnet pressing plate 27 through circuit control to make electromagnet pressing plate 27 circular telegram will treat that the stamping workpiece adsorbs fixedly, and electromagnet pressing plate 27 still can carry out magnetic adsorption to telescopic link 28 simultaneously, then telescopic link 28 can adsorb fixedly with iron plate 38, is equivalent to fixed connection between telescopic link 28 and the iron plate 38 this moment.

Meanwhile, when the second rotary table 24 rotates, the second arc plate 25 is driven to rotate through the sliding fit action between the second slide block 26 and the second arc groove 40, so as to drive the second swing rod 23 to swing, because the arc surface of the second arc plate 25 faces the arc surface of the first arc plate 6 in the opposite direction, and the movement track of the second slide block 26 partially coincides with the arc track of the second arc groove 40, when the first slide block 8 drives the first swing rod 4 to swing, the second swing rod 23 is in the stopped state, and when the first swing rod 4 stops rotating, the second slide block 26 rotates out of the coincidence part with the second arc groove 40, at this time, the second slide block 26 drives the second swing rod 23 to swing through the sliding fit with the second arc groove 40, so as to drive the second connecting rod 21 and the mounting slide block 22 to slide downwards along the inner wall of the mounting chute 20, and further drive the punching pipe cutter 29 at the bottom of the mounting slide block 22 to move downwards, therefore, the center of the to-be-punched part of the formed basin-shaped cavity is punched, and the second swing rod 23 can have an accelerating effect while swinging due to the fact that the second slide block 26 is matched with the cambered surface of the second arc-shaped groove 40, so that the punching pipe cutter 29 can punch holes cleanly, burrs at the punching hole can be reduced, and the punching effect is improved.

After punching, the first swing rod 4 and the second swing rod 23 are driven to swing upwards along with the continuous rotation of the second rotating shaft 39, so as to drive the lifting block 13 and the mounting slide block 22 to move upwards for resetting, the cylinder 15 is driven to move upwards together when the punching column 14 moves upwards, at the moment, the electromagnet pressing plate 27, the telescopic rod 28 and the iron block 38 are fixed by adsorption through magnetism, so that the electromagnet pressing plate 27 can be prevented from ejecting the stamping part under the elastic action of the spring 33, the stamping part can move upwards along with the electromagnet pressing plate 27 so as to be separated from the placing groove 34, demoulding of the stamping part is realized, and meanwhile, when the cylinder 15 moves upwards, the limiting block 18 can slide along the inner wall of the limiting groove 16 under the limiting action of the elastic wedge block 36, so as to drive the cylinder 15 to rotate, so as to drive the electromagnet pressing plate 27 to rotate through the telescopic rod 28, at the moment, because the stamping part is contacted with the cambered surface at the bottom end of the stamping column 14, the inner wall of the basin-shaped cavity of the stamping part can be polished along with the rotation of the electromagnetic pressing plate 27, and simultaneously, the bottom end of the stamping column 14 can also be polished, the surface quality of the stamping part is further improved, meanwhile, when the stamping part and the stamping column 14 rotate relatively, the wrapping force action of the stamping part on the bottom end of the stamping column 14 can be overcome, so that no action force exists between the stamping part and the stamping column 14, then when the limiting block 18 is contacted with another trigger switch 37 along with the rising and the rotation of the cylinder 15, the electromagnetic pressing plate 27 is powered off through circuit control, at the moment, the stamping part and the electromagnetic pressing plate 27 are released from being fixed, thereby falling, the effect of blanking after polishing is achieved, meanwhile, the telescopic rod 28 and the iron block 38 are released from being fixed, under the elastic force action of the spring 33, and the telescopic rod 28 and the electromagnet pressing plate 27 are pulled down and reset, so that the punching and punching process is completed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
