Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 6 , in the embodiment of the present invention, a punching device for air ring processing with a feeding structure includes two drive wheels 1. The outer peripheries of the two drive wheels 1 are drivingly connected with a drive belt 2. A plurality of limit plates 3 are equidistantly distributed on the outer periphery of the drive belt 2. The distance between two adjacent limit plates 3 is equal to the width of the fixing plate 6. Both ends of the two drive belts 2 are fixedly installed with rotating shafts. The end of the rotating shaft far from the drive belt 2 is rotatably installed with a side plate 4. The bottoms of the two side plates 4 are connected by a C-shaped rod; a stamping mechanism for punching the fixing plate 6 is installed outside the limit plate 3 at the end of the drive belt 2, and a one-way driving mechanism connected to one drive wheel 1 is installed on the stamping mechanism.

[0025] In this embodiment: First, place the fixing plate 6 between two limit plates 3 at the head end of the drive belt 2. Then, the stamping mechanism drives one drive wheel 1 to rotate through the one-way driving mechanism. The drive wheel 1 drives the other drive wheel 1 to rotate through the drive belt 2. The drive belt 2 can drive the fixing plate 6 to move towards the end of the drive belt 2 through the limit plates 3. The stamping mechanism moves upward and drives one drive wheel 1 to rotate through the one-way driving mechanism. The hot stamping mechanism moves downward and cannot drive the drive wheel 1 to rotate through the one-way driving mechanism;

[0026] The distance that the one-way driving mechanism drives the drive wheel 1 to rotate is equal to the width of the fixing plate 6, that is: after each fixing plate 6 is punched, it will move forward by one unit distance.

[0027] Please refer specifically to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, the stamping mechanism includes two connecting frames 7 fixedly connected to one end of a side plate 4. At the top of the two connecting frames 7, a lower stamping die 8 is fixedly installed. On both sides of the lower stamping die 8, guide sleeves 9 are fixedly installed. Inside the annular part of the guide sleeve 9, a guide rod 12 is slidably connected up and down. At the top of the guide rod 12, a fixed ear is fixedly connected. Inside the fixed ear, an upper stamping die 11 is fixedly connected. Below the lower stamping die 8, a hydraulic cylinder 10 is installed. The output end of the hydraulic cylinder 10 penetrates above the lower stamping die 8 and is connected to the bottom end of the upper stamping die 11. The bottom end of the hydraulic cylinder 10 is fixed on the support surface; at the bottom end of the upper stamping die 11, a stamping head 17 is installed. Inside the lower stamping die 8, a stamping hole 18 is opened and aligned with the stamping head 17 in the up and down direction.

[0028] In this embodiment: By starting the reciprocating movement of the hydraulic cylinder 10, the hydraulic cylinder 10 drives the upper stamping die 11 to move up and down, and the upper stamping die 11 drives the stamping head 17 to move synchronously. The downward stamping head 17 cooperates with the stamping hole 18 to perform a punching operation on the fixing plate 6.

[0029] Please refer specifically to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the one-way driving mechanism includes a connecting rod 15 fixedly installed between two fixed ears. At the bottom end of the connecting rod 15, a vertical rod 16 is fixedly connected. Inside the vertical rod 16, a rotating column 22 is rotatably installed. At one end of the rotating column 22, a ratchet tooth 19 is fixedly connected. At the other end of the rotating column 22, a protruding plate is formed. A torsion spring 23 is engaged between the protruding plate and the vertical rod 16; inside the vertical rod 16, an arc-shaped groove 20 is opened and coincides with the center of the rotating column 22. At an eccentric position at one end of the ratchet tooth 19, a movable column 21 is fixedly connected and is movably connected to the arc-shaped groove 20; on the outer wall of the rotating shaft at one end of a transmission belt 2, a ratchet wheel 13 meshing with the ratchet tooth 19 is fixedly assembled.

[0030] In this embodiment: when the upper stamping die 11 moves up and down, the upper stamping die 11 drives the vertical rod 16 to move synchronously through the connecting rod 15. When the vertical rod 16 moves from top to bottom, the vertical rod 16 drives the multiple ratchets 19 to move downward. When the ratchet 19 contacts the ratchet wheel 13, the inclined surface of the ratchet 19 contacts the inclined surface of the ratchet wheel 13. At this time, the ratchet 19 rotates upward from the initial state under the reaction force of the extrusion force, and the ratchet 19 drives the rotating column 22 to rotate. At this time, one end of the torsion spring 23 engaged with the protruding plate of the rotating column 22 is twisted, and the other end of the torsion spring 23 engaged with the vertical rod 16 remains stationary. Therefore, the torsion spring 23 is twisted. Therefore, when the vertical rod 16 drives the ratchet 19 to move from top to bottom, the ratchet wheel 13 cannot be driven to rotate, that is: when the upper stamping die 11 moves downward to punch the fixed plate 6, the transmission wheel 1 and the transmission belt 2 remain stationary, so that the fixed plate 6 remains stationary;

[0031] After the ratchet 19 and the ratchet wheel 13 are misaligned, the torsion spring 23 is reset, and the rotating column 22 is driven to reset and rotate, thereby driving the ratchet 19 to reset;

[0032] After the punching is completed, the upper punching die 11 moves from bottom to top. At this time, the upper punching die 11 drives the vertical rod 16 to move upward through the connecting rod 15. The vertical rod 16 moving upward drives the ratchet 19 to move upward. At this time, the ratchet 19 is engaged with the ratchet wheel 13. Therefore, the multiple ratchet teeth 19 moving upward drive the ratchet wheel 13 to rotate, so that the fixed plate 6 with the punching completed can be moved out from the bottom of the upper punching die 11, and the next fixed plate 6 moves to the bottom of the upper punching die 11;

[0033] It should be noted that: through size design, when the ratchet 19 drives the ratchet 13 to rotate, the length of the angle of rotation of the ratchet 13 driving the transmission wheel 1 is just enough to move the fixing plate 6 forward by the sum of the width of one fixing plate 6 and the width of one limiting plate 3.

[0034] Please refer to Figure 1 and Figure 2 The outer sides of the two side plates 4 are connected with guide plates 5 through fixing rods. The guide plates 5 are located above the side plates 4. The two guide plates 5 are distributed in an "eight" shape. The spacing between the straight plate parts of the two guide plates 5 is equal to the length of the fixing plate 6. The two guide plates 5 cooperate to correct the fixing plate 6 to a preset position.

[0035] In this embodiment: an operator sequentially places a plurality of fixed plates 6 into the limit plate 3. After placement, as the transmission belt 2 moves, one end of the fixed plate 6 contacts the inclined surface of the guide plate 5, and the inclined surface of the guide plate 5 squeezes the fixed plate 6, so that the fixed plates 6 are neatly arranged, and one end of the fixed plate 6 protrudes from the transmission belt 2.

[0036] Please refer to Figure 3, a receiving rack 14 protruding outward is formed at the overlapping position of a side plate 4 and the unidirectional driving mechanism.

[0037] In this embodiment: the cross-section of the receiving rack 14 is in a "C" shape, so as to prevent the side plate 4 from interfering with the up and down movement of the unidirectional driving mechanism.

[0038] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
