in the practical use process of the invention, firstly, a wire clamping mechanism driving motor 303 is started, a wire clamping claw 313 is driven to move to the position of a paying-off mechanism 1 through a wire clamping mechanism sliding block 305, the wire clamping claw 313 is driven to move downwards through a wire clamping claw descending cylinder 307 to clamp a cut wire on the paying-off mechanism 1, the clamped wire clamping claw 313 is lifted and reset after clamping, the wire clamping mechanism driving motor 303 overturns to drive the wire clamping claw 313 to translate back to the original position, the wire clamping claw 313 which moves back to the original position is driven by the wire clamping claw descending cylinder 307 to move downwards again, the wire clamped on the wire clamping claw 313 is placed in a wire storage groove on the top surface of an overturning wheel 45 in an overturning mechanism 4, after the placement is finished, the wire clamping claw 313 is lifted and reset, an overturning wheel motor 42 is started to drive the overturning wheel 44 to rotate 90 degrees towards one side of a vertical forming mechanism 6, the wire in the wire storage groove of an overturning wheel insert 45 on the rotating wheel 44 just falls into an insert 58 on the top of a wire clamping wire feeding assembly 5, then the wire feeding motor 52 is started, the wire feeding screw 53 is driven to drive the whole forming adjusting plate 55 to move towards the top surface of a forming die 608 in the vertical forming mechanism 6, after the wire placed in the wire placing groove 58 reaches a preset forming and punching position, the middle punching cylinder 612 is started to drive the punching slide block 613 and the middle punching plate 614 at the bottom of the punching slide block to press down the wire pressed and butted against the wire placing groove 58 for middle punching, then the side punching cylinders 620 at the two sides are started to drive the side punching slide block 625 and the side punching roller handle 623 on the surface of the side punching slide block to press down the two ends of the wire, so that the wire is punched to form a U-shaped finished product, after punching, the side punching roller handle 623 and the middle punching plate 614 are lifted and reset, finally the material returning cylinder 609 is started, the material returning tile pressing plate 606 drives the material returning tile 607 to extend forward, the coil pressed on the forming die 608 is pushed forward to the material returning tile 7 by the material returning tile 607, and slides to the material discharging rod 83 along the inclined plane of the material discharging rod 7 for collection.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, it should be noted that, for those skilled in the art, many modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
