The working process of the invention is as follows: in the initial state, the swinging plate A12 and the swinging plate B19 are in horizontal positions and are positioned in the plate groove 4; spur rack 46 is located above gear a36 and is not meshed with gear a 36; the inner plate of the expansion plate 50 is separated from the spur rack 46, and the inclined surface at the end of the outer plate of the expansion plate 50 is in contact fit with the inclined surface at the lower end of the vertical section of the L-shaped plate 55; a limiting groove 47 on the side surface of the straight rack 46 is positioned above the upper surface of the vertical section of the L-shaped base 1; the lower surface of the horizontal section of the L-shaped plate 55 is at a certain distance from the lower pressure spring plate 48; the two arc-shaped blocks 23 are positioned in the two clamping grooves 6 on the inner wall of the plate groove 4, so that the material plate 61 positioned on the swinging plate B19 cannot move along with the swinging plate B19 when being stamped; the two tooth blocks 22 are not in driving connection with the upper tooth flanks of the partial gear 18.

When the material plate 61 needs to be stamped, the material plate 61 is conveyed to and placed on the upper surface of the swinging plate B19 through conveying equipment, and the lower surface of the material plate 61 is in contact fit with the die holder 60; then, the punch 59 is started to punch; the punch 59 starts to drive the L-plate 55 downward along the guide rail a 57; the inclined plane of the vertical section of the L-shaped plate 55 acts on the inclined plane of the outer plate of the telescopic plate 50, so that the outer plate of the telescopic plate 50 drives the tension spring disc 53 to synchronously move towards the direction of the spur rack 46 along the chute C9, and the spring B54 is stretched and stores energy; the inner plate of the expansion plate 50 is contacted with the side surface of the spur rack 46 and contracts into the outer plate of the expansion plate 50 under the action of the side surface of the spur rack 46, and a compression spring in the outer plate of the expansion plate 50 is compressed and stores energy; when the lower surface of the horizontal section of the L-shaped plate 55 is in contact with and interacts with the pressure spring plate 48, the inclined surface at the lower end of the vertical section of the L-shaped plate 55 is separated from the inclined surface of the outer plate of the expansion plate 50, and the side surface of the vertical section of the L-shaped plate 55 starts to be in contact fit with the outer plate of the expansion plate 50, so that the outer plate of the expansion plate 50 keeps still under the combined action of the spring B54 and the L-shaped plate 55; the L plate 55 which continues to move downwards presses the compression spring plate 48 to drive the spur rack 46 to move downwards along the sliding groove A7, and the spring A49 compresses and stores energy; spur rack 46 begins to encounter and mesh with gear a36, and spur rack 46 drives gear a36 to rotate; since the one-way clutch 35 overruns at this time, the gear a36 cannot drive the rotating shaft a34 to rotate through the one-way clutch 35; meanwhile, the limiting groove 47 on the side surface of the spur rack 46 is gradually close to the inner plate bevel end of the expansion plate 50; when the limiting groove 47 on the spur rack 46 meets the inner plate of the telescopic plate 50, under the reset action of the compression spring in the telescopic plate 50, the inner plate of the telescopic plate 50 instantly enters the limiting groove 47 and limits the reset motion of the spur rack 46; at this time, the punch 59 just ends punching the material plate 61 and stops moving downward, and the spur rack 46 moves downward to the limit position.

When the punching of the punch 59 on the material plate 61 is finished, the L plate 55 is driven to move upwards for resetting; due to the restriction of the inner plate of the telescopic plate 50 to the spur rack 46, the spur rack 46 still remains stationary, and the L-plate 55 and the pressure spring plate 48 start to separate; when the inclined plane at the lower end of the vertical section of the L-plate 55 meets the inclined plane at the end of the outer plate of the expansion plate 50, the tension spring disc 53 drives the outer plate of the expansion plate 50 to perform a restoring motion under the restoring action of the spring B54; the outer plate of the telescopic plate 50 drives the inner plate of the telescopic plate 50 to quickly reset through the two guide blocks B52, and the inner plate of the telescopic plate 50 quickly relieves the limitation on the straight rack 46; under the reset action of the spring A49, the compression spring plate 48 drives the spur rack 46 to reset quickly; spur rack 46 drives gear a36 to rotate in reverse; since the one-way clutch 35A plays a role of one-way driving at this time, the gear a36 drives the rotating shaft a34 to synchronously rotate through the one-way clutch 35A; the rotating shaft A34 drives the belt wheel A33 and the belt wheel C37 to synchronously rotate; the belt wheel A33 drives the gear C28 to rotate sequentially through a synchronous belt A32, a belt wheel B31, a rotating shaft B30 and a gear B29, and the rotating direction of the gear C28 is opposite to that of the gear A36; the gear C28 drives the swing plate A12 to swing upwards around the swing shaft 62 through the arc-shaped rack 16 meshed with the gear C, the swing plate A12 drives the swing plate B19 and the material plate 61 positioned on the swing plate B19 to synchronously swing upwards, and the upper surface of the swing plate B19 begins to gradually incline.

Meanwhile, the belt wheel C37 drives the shifting wheel 44 to rotate sequentially through a synchronous belt B38, a belt wheel D39, a rotating shaft C40, a gear D41, a gear E42 and a rotating shaft D43; the dial wheel 44 drives a plurality of dial plates 45 positioned on the dial wheel to rotate around a rotating shaft D43; the direction of rotation of the thumb wheel 44 is the same as the direction of rotation of the gear C28.

When the punch 59 drives the spur rack 46 to move to the initial position through the L plate 55, the swing plate A12 drives the swing plate B19 and the waste plate 61 to swing to the highest position around the swing shaft 62, and the shifting plate 45 on the shifting wheel 44 rotates around the rotating shaft D43 in the movable groove A14 and the movable groove B21; due to the existence of the movable end movable groove A14 of the swinging plate A12 and the movable groove B21 of the upwarping end of the swinging plate B19, the shifting plate 45 on the shifting wheel 44 does not form a barrier to the movement of the swinging plate; because the rotating direction of the shifting wheel 44 is consistent with the upward swinging direction of the swinging plate A12 around the swinging shaft 62, when the swinging plate B19 drives the waste plate 61 to swing up to the shifting wheel 44 around the swinging shaft 62, the shifting plate 45 on the shifting wheel 44 cannot block the upward swinging of the waste plate 61, and the waste plate 61 on the upper surface of the swinging plate B19 is continuously shifted by a plurality of shifting plates 45 at the tail end thereof to slide down along the swinging plate B19 obliquely through the inclined plane at the tail part of the L-shaped base 1 and slide into the waste recovery container.

When the waste material plate 61 on the swinging plate B19 slides backwards from the swinging plate B19, the swinging plate A12 swings downwards to an initial position under the action of torque generated by the gravity of the swinging plate A12 and the swinging plate B19, the arc-shaped rack 16 drives the gear C28 to rotate reversely in the swinging process of the swinging plate A12, the gear C28 sequentially passes through the gear B29, the rotating shaft B30, the belt wheel B31, the synchronous belt A32, the belt wheel A33, the rotating shaft A34 and the one-way clutch 35 to drive the gear A36 to rotate, and the gear A36 is completely separated from the straight rack 46 at the moment, so the resetting of the swinging plate A12 and the swinging plate B19 is not hindered; in the process of resetting the swing plate A12 and the swing plate B19, the rotating shaft A34 drives the thumb wheel 44 to rotate reversely through the belt wheel C37, the synchronous belt B38, the belt wheel D39, the rotating shaft C40, the gear D41, the gear E42 and the rotating shaft D43.

When the swing plate A12 drives the swing plate B19 and the waste material plate 61 to swing upwards by a certain small angle around the swing shaft 62, the two arc-shaped blocks 23 positioned at the two sides of the swing plate B19 are separated from the clamping grooves 6 at the two sides of the plate groove 4; after the two arc-shaped blocks 23 are separated from the corresponding clamping grooves 6, the two tooth blocks 22 positioned at the two sides of the swing plate B19 respectively meet and interact with the tooth surfaces on the two incomplete gears 18, and the tooth surfaces of the incomplete gears 18 drive the swing plate B19 to move on the surface of the swing plate A12 along the straight trapezoidal guide groove 15 through the two tooth blocks 22; under the action of a spring C25, the swinging plate B19 slides on the upper surface of the swinging plate A12 in a reciprocating manner along the straight trapezoidal guide groove 15, and shakes the waste material plate 61 on the swinging plate B19; burrs generated after the material plate 61 is punched interact with the edge of the square groove C20 on the swing plate B19, and the material plate is difficult to smoothly slide from the swing plate B19, so the swing plate B19 which shakes in a reciprocating manner separates the waste material plate 61, and the waste material plate 61 is favorable for smoothly sliding from the swing plate B19; when the swinging plate A12 drives the swinging plate B19 to reset, under the action of the incomplete gear 18 and the gear block 22, the swinging plate B19 still reciprocates along the surface of the swinging plate A12; when the incomplete gear 18 is separated from the tooth block 22, the reciprocating motion of the swinging plate B19 is stopped; when the swing plate A12 drives the swing plate B19 to move to the initial position, the two arc-shaped blocks 23 enter the corresponding clamping grooves 6 again.

After the swing plate a12 and the swing plate B19 are swung to the initial position, the material plate 61 is conveyed onto the swing plate B19 again by the conveying mechanism and is stamped, and the stamping process is as described above.

In the invention, when the punch 59 finishes the process of stamping and moving upwards, the swing plate drives the waste material plate 61 to tilt upwards around the swing shaft 62, when the punch is about to reach the initial position, the punch is far away from the waste material plate 61 for a large distance, and at the moment, the swing plate A12 swings; the punching hole punched on the waste plate 61 can not be sleeved on the punch of the punch 59, so that the waste plate 61 is prevented from touching the punch, damage to the punch is avoided, and the next punching is guaranteed to be smoothly carried out.

In conclusion, the invention has the beneficial effects that: according to the invention, after each punching of the punch 59, the punched waste material plate 61 can be automatically cleaned through the matching of the swing plate A12 swinging around the swing shaft 62 and the swing plate B19, the punching is cleaned once, the waste material plate 61 is not stacked on the die holder 60, and the punching work can be smoothly carried out; compared with the traditional cleaning process of the waste material plate 61 after stamping, the waste material plate 61 on the die holder 60 is automatically and timely cleaned, the waste material plate 61 is not stacked on the die holder 60, the punching machine 59 does not need to be temporarily stopped when the waste material plate 61 is cleaned, the waste material plate 61 is automatically cleaned immediately after the punching machine 59 finishes punching once, the continuous punching operation is not influenced, the working efficiency is high, certain safety is realized, and the potential safety hazard of the traditional waste material plate 61 in the manual cleaning process is avoided.
