Specifically, the rack plate 53 and the gear 52 form a unidirectional rotation structure; the adjusting plate 51 is provided with a reset torsion spring; the distance between the two guide rods 54 is matched with the outer diameter of the circular arc section in the hoop so as to stably clamp the hoop in the middle, and the adjusting plate 51 is positioned between the two guide rods 54; during the stamping process, the adjusting plate 51 is enclosed on the outer side of the plate; after the plate is stamped into the stay anchor ear, the upper die 102 moves upwards to reset, the rack plate 53 drives the adjusting plate 51 to rotate, meanwhile, the push rod 103 pushes the anchor ear outwards, and at the moment, the anchor ear with the upper gravity center begins to rotate along with the adjusting plate 51; the two guide rods 54 abut against the two ear plates in the hoop, so that after the adjusting plate 51 is separated from the hoop, the hoop is finally deflected to a posture with a downward gravity center, and then the hoop slides along the guide rods 54 into the collecting frame 56, so that the hoop can be automatically stacked.

Before the plate is subjected to punch forming, the plate is placed in the transmission table 104 and stably moves in the positive direction along the X axis until the right end of the plate touches the trigger rod 24, and the trigger rod 24 is extruded to move to the right; panels for limiting the plates can be arranged on the front side and the back side of the upper die 102, so that the plates are prevented from shaking forwards and backwards, and the stability of the plates in the transmission process is improved;

in the process that the trigger rod 24 moves to the right, the poking plate 43 drives the clamping rod 41 to rotate, so that the clamping rod 41 is separated from the clamping groove 42, and the two clamping jaws 21 are pushed by the spring part to approach each other respectively, so that the right end of the plate is clamped; after the clamping jaw 21 fixedly clamps the plate, the positioning work for the plate operation is also completed;

then, the fastening plate 32 is extruded to the inside of the inner slide rail 31 by the trigger rod 24 which moves to the right, at this time, the slide carriage 22 is in a state of sliding downwards after being pressed, the trigger rod 24 which moves to the right keeps stable in position under the action of the positioning component 28, and a damping component can be arranged at the connection position between the slide carriage 22 and the inner slide rail 31, so that the slide carriage 22 cannot slide easily, and the stability of the slide carriage 22 is further improved;

starting the upper die 102 to move downwards along the Y axis, cutting the plate by the cutter 105, and punching the plate into the hoop by matching the upper die 102 with the lower die 101;

in the conventional press, both sides of the bottom of the upper die 102 simultaneously press the sheet material, so that both ends of the sheet material deflect and deform downward, and in the process, the sheet material may be shifted in the X-axis direction; in the scheme, the right end of the plate is clamped by the clamping jaw 21, so that the possibility of the plate offset is reduced, and the dimensional stability of the plate after punch forming is improved;

after the upper die 102 moves down, the pulling plate 36 in the upper die 102 also moves to below the driven rod 351;

at the initial stage of stamping, the plate deforms along the semicircular surface in the lower die 101, at the moment, the motion track of the right end of the plate is an arc track concentric with the circle center of the lower die 101, and by arranging the concentric arc inner sliding plate, the clamping jaw 21 always clamps the plate in the deformation process of the plate, so that the possibility of plate deviation is reduced;

in the middle stage of stamping, because the plate material is partially attached to the outer surface of the lower die 101, the plate material at this time is not substantially deflected on the X axis, and by providing the reset rod 44, along with the continuous deformation of the plate material, the slide carriage 22 continues to move along the inner slide rail 31 until the trigger rod 24 contacts with the reset rod 44, and the trigger rod 24 and the reset rod 44 are extruded and move back to the left; the slide 22 is always positioned between the driven rod 351 and the push rod 352 in the process of moving up and down;

the reset rod 44 moving to the left drives the toothed ring 26 and the clamping jaw 21 to rotate through the ratchet 27, so that the clamping jaw 21 is opened outwards and the plate is loosened, and the continuous deformation of the plate is prevented from being hindered; then, the lower die 101 can continue to extrude the plate to deform until the plate is stamped into the hoop;

after the clamping jaw 21 rotates, the clamping rod 41 clamps the clamping jaw 21 again;

after the punching is finished, the upper die 102 moves upwards to reset, and the driven rod 351 is driven by the pull rod to move upwards, so that the push rod 352 can push the sliding seat 22 to move upwards to reset, and the sliding seat 22 after moving upwards is clamped by the fastening plate 32 again;

the upper die 102 moving upwards drives the adjusting plate 51 to rotate through the rack plate 53, and the push rod 103 pushes out the formed hoop in the positive direction along the Z axis; the hoop with the upper gravity center falls onto the guide rod 54 along with the adjusting plate 51;

with the continuous rotation of the adjusting plate 51, the adjusting plate 51 is separated from the hoop, the adjusting plate 51 is returned under the action of the return torsion spring, and the hoop is adjusted to a posture with a downward gravity center and is stopped between the two guide rods 54 and stably slides to the baffle 55 along the guide rods 54; finally, the anchor ear keeps the posture that the focus is down to the collection frame 56 in the gap between baffle 55 and guide bar 54 in, so, can realize the automatic function of piling up of anchor ear in collecting frame 56 after the shaping, save the artifical trouble of picking up and stacking the anchor ear, moreover, the steam generator is simple in structure, convenient for operation, the work efficiency is improved, the integrated device can reset automatically, but the cycle work, be suitable for unmanned assembly line automatic production, and need not additionally to set up electric drive mechanism, low in use cost.
