The working principle and the using process of the invention are as follows:

before punching, the distance between the positioning clamp 18 and the flat clamp 19 is in the maximum state;

when the conjoined support is installed, the clamping groove on the conjoined support is aligned with the positioning clamp 18, then the conjoined support is clamped on the positioning clamp 18, the driving motor 3 is started, the driving motor 3 drives the bidirectional ball screw 4 to rotate, the two meshing plates 14 are driven to move oppositely through the meshing of the two meshing plates 14 and the bidirectional ball screw 4, and the two meshing plates 14 can drive the extension rod 17 and the top plate 11 to move when moving;

when the top plate 11 moves, the steering gear 10 is meshed with the rack 13, so that when the top plate 11 moves towards the center of the tool platform 2, the steering gear 10 drives the bottom plate 12 to move towards the opposite direction, the bottom plate 12 drives the locking plate 8 to move towards one end far away from the center of the tool platform 2 through the connecting rod 7, the locking plate 8 is inserted into the bottom end of the locking groove 16, and locking between the tool platform 2 and the locking platform 15 is realized;

meanwhile, when the meshing plate 14 moves, the two extension rods 17 drive the positioning clamp 18 and the flat clamp 19 to move towards the center of the tooling platform 2, so that the flat clamp 19 is attached to the other surface of the connected bracket, and the connected bracket is clamped in the middle of the positioning clamp 18 and the flat clamp 19;

then, a punching mechanism arranged at the top end of the punching equipment main body 1 works to punch the fixed conjoined support;

after punching is finished, the driving motor 3 drives the bidirectional ball screw 4 to rotate reversely, so that the meshing plate 14 drives the positioning clamp 18 and the flat clamp 19 to move reversely through the extension rod 17, and meanwhile, as the magnetic force of the strong magnetic plate 20 is larger than that of the weak magnetic plate 26, when the flat clamp 19 is separated from the positioning clamp 18, the magnetism of the strong magnetic plate 20 drives the conjoined support to be adsorbed on the left side surface of the flat clamp 19 and drives the conjoined support to move rightwards along with the right movement of the flat clamp 19;

when the engaging plate 14 moves rightwards, the engaging plate 11 is driven to move rightwards, and after the rack 13 arranged on the bottom surface of the engaging plate 11 is engaged with the steering gear 10 again, the steering gear 10 can drive the locking plate 8 to move towards the middle of the tooling platform 2 in the inner cavity of the locking groove 16, so that the locking plate 8 and the locking groove 16 are unlocked;

when the two extension rods 17 drive the positioning clamp 18 and the flat clamp 19 to separate, the conjoined support is adsorbed on the flat clamp 19, when the flat clamp 19 drives the right end of the ejector rod 23 to contact with the fixed plate 21 through the strong magnetic plate 20 and the limiting pipe 22, the fixed plate 21 limits the movement of the ejector rod 23, and the flat clamp 19 still drives the conjoined support to move rightwards, so that the left end of the ejector rod 23 extends out of the left side of the flat clamp 19, and the conjoined support is ejected out, thereby realizing the automatic blanking of the conjoined support after the punching is finished;

meanwhile, when the connected bracket is ejected out by the ejector rod 23, the next connected bracket to be punched can be arranged on the surface of the positioning clamp 18 while the connected bracket is blanked because the surface of the positioning clamp 18 is not shielded;

when the flat clamp 19 moves towards the center of the tooling platform 2 again, the ejector rod 23 is separated from the fixed plate 21 at the moment, and the return spring 25 in a compressed state pushes the limiting plate 24 to the right side, so that the ejector rod 23 is driven to move rightwards, the left side surface of the ejector rod 23 and the left side surface of the flat clamp 19 are located on the same vertical plane again, and the ejector rod 23 is reset.
