[0022] Such asFigure 1 , 3 As shown in 3 , this embodiment provides a progressive die floating material conveying mechanism, which includes an upper die base 1 and a lower die base 2. A cam component is installed on the upper die base 1, a punching component is installed on one side of the cam component, and a punch 3 is installed on the lower die base 2.

[0023] The cam component includes a mounting seat 16, which is fixedly installed on the upper die base 1 through a positioning key. A cam base 17 is fixedly installed on the mounting seat 16, and a cam 18 is slidably installed on the cam base 17. A reset nitrogen spring is arranged between one end of the cam 18 and the cam base 17. After the punching is completed and the die is separated, the cam 18 is pushed by the reset nitrogen spring to slide and reset on the cam base 17, and the punching component is installed on one side of the cam 18; the punching component includes a punch hard material backing plate 20 fixedly connected to one side of the cam 18, a punch 21 is fixedly installed on the punch hard material backing plate 20, a blank holding core 22 is arranged on one side of the punch hard material backing plate 20, and the punch hard material backing plate 20 and the blank holding core 22 are connected by a buffer nitrogen spring 23. One end of the punch 21 penetrates through the blank holding core 22, and guide plates are fixedly connected to both sides of the blank holding core 22. Corresponding guide openings are formed on both sides of the punch hard material backing plate 20, and the guide plates are slidably arranged in the guide openings; a guide block 19 is fixedly connected to the lower die base 2, and the guide block 19 is slidably connected to the lower side of the cam 18. When the workpiece needs side punching, the upper die base 1 drives the mounting seat 16, the cam base 17 and the cam 18 to move downward. The cam 18 moves downward and is clamped with the guide block 19, and slides on the guide block 19 as the upper die base 1 continues to move downward. The blank holding core 22 contacts the workpiece as the cam 18 moves and clamps the workpiece on the punch 3, and the buffer nitrogen spring 23 contracts. The punch 21 passes through the blank holding core 22 to perform side punching on the workpiece.

[0024] As Figure 2 shown in Figure 2 , a lifting mechanism is arranged at one end of the lower die base 2. The lifting mechanism includes a lifting nitrogen spring 9, which is fixedly installed on the lower die base 2. A floating plate 10 is installed on the output end of the lifting nitrogen spring 9. The lifting nitrogen spring 9 drives the floating plate 10 to rise and fall as the upper die base 1 rises and falls. The upper die base 1 moves downward and contacts and squeezes the lifting nitrogen spring 9, causing the floating plate 10 to move downward. After the upper die base 1 separates and moves upward after the die closing is completed, the lifting nitrogen spring 9 resets as the upper die base 1 moves upward, thereby driving the floating plate 10 to move upward.

[0025] A guide rod 11 is fixedly connected to the lower end of the floating plate 10. A guide hole is formed on the lower die base 2, and the guide rod 11 is slidably arranged in the guide hole. The floating plate 10 moves up and down through the guidance of the guide rod 11.

[0026] As Figure 4As shown, a conveying mechanism is movably provided on the upper side of the lower die base 2, and the conveying mechanism is used to convey the workpiece after punching. The conveying mechanism includes a conveying frame 4, and the conveying frame 4 is provided with two groups. The conveying frames 4 are respectively arranged on both sides of the punch 3, and one end of the conveying frame 4 is movably connected with the floating plate 10. The floating plate 10 is provided with a connecting groove, and the end of the conveying frame 4 is connected to a mounting block, and the mounting block is slidably arranged in the connecting groove. One end of the conveying frame 4 is lifted and lowered together with the floating plate 10, and the conveying frame 4 is lifted and lowered to contact and eject the workpiece after processing. The ejected workpiece falls on the conveying frame 4 and is transported to the outside through the conveying frame 4. The conveying roller wheel facilitates the smooth conveying of the workpiece on the conveying frame 4. The conveying roller can be driven by a driving motor and a power transmission mechanical structure to rotate and convey, thereby further improving the conveying efficiency. A base 5 is fixedly connected to one side of the lower die base 2, and the conveying frame 4 is rotatably installed on the base 5. The conveying frame 4 rotates on the base 5 as the floating plate 10 rises and falls. A pushing block 6 is slidably installed on the conveying frame 4, and a traction rope 7 is fixedly connected to one side of the pushing block 6. One end of the traction rope 7 extends through one end of the conveying frame 4 and is fixedly connected to the lower die base 2. A reset spring is fixedly connected to the other side of the pushing block 6, and the other end of the reset spring is fixedly connected to the conveying frame 4.

[0027] The conveying frame 4 rotates on the base 5 and the traction rope 7 is pulled to make the pushing block 6 slide on the conveying frame 4, so that the workpiece is pushed to move on the conveying frame 4 by the pushing block 6; a limiting block 8 is fixedly connected to the lower side of the conveying frame 4, and the traction rope 7 movably passes through the limiting block 8, and the limiting block 8 limits the position of the traction rope 7.

[0028] A return spring is fixedly connected to the other side of the push block 6, and the other end of the return spring is fixedly connected to the conveying frame 4. After the conveying frame 4 rotates and resets, the push block 6 is pulled to reset by the return spring, which is convenient for the subsequent pushing of the workpiece to be processed.

[0029] like Figure 5 As shown, a material blocking buffer mechanism is provided at the other end of the lower die base 2, and the material blocking buffer mechanism includes a material unloading frame 12, and the material unloading frame 12 is provided with a buffer plate 13 of the lower die base 2, and a mounting groove 14 is provided on the material unloading frame 12 corresponding to the conveying frame 4, and a rotating shaft 15 is fixedly installed in the mounting groove 14, and the buffer plate 13 is rotatably installed on the rotating shaft 15, and a torsion spring is sleeved on the rotating shaft 15, and the two ends of the torsion spring are respectively connected to the buffer plate 13 and the inner wall of the mounting groove 14, and one end of the buffer plate 13 contacts the end of the conveying frame 4. As the conveying frame 4 turns over, the end of the conveying frame 4 that contacts the buffer plate 13 moves downward, so that the buffer plate 13 rotates on the rotating shaft 15, and the other end is tilted to block the conveyed workpiece, so that the staff can take it easily.

[0030] During processing, the workpiece is placed on the punch 3. The upper die holder 1 moves downward. The angle wedge 18 docks with the guide block 19 as the upper die holder 1 moves downward. The upper die holder 1 continues to move downward to push the angle wedge 18 to slide on the guide block 19, so that the blank holder 22 cooperates with the punch 3 to clamp the workpiece. The punch 21 passes through the blank holder 22 to perform side punching on the workpiece. After processing, the upper die holder 1 and the lower die holder 2 are separated. The upper die holder 1 releases the pressing on the lifting nitrogen spring 9. The lifting nitrogen spring 9 resets and lifts, driving one end of the conveying frame 4 to rise through the floating plate 10, so that the conveying frame 4 rotates along the base 5 to become an inclined state. The rising end of the conveying frame 4 lifts the workpiece and makes it fall onto the conveying frame 4, enabling the workpiece to slide along the inclined surface of the conveying frame 4. When the conveying frame 4 rotates, the rising end of the conveying frame 4 pulls the pushing block 6 to slide through the towing rope 7 to push the workpiece on the conveying frame 4 to ensure the smoothness of material conveyance. When the conveying frame 4 rotates, it presses one end of the buffer plate 13 downward, causing the other end of the buffer plate 13 to tilt upward to block the end of the conveying frame 4, making the workpiece fall onto the blanking frame 12 for placement, facilitating the operator to pick it up.
