Through the arranged stamping mechanism, stamping of the workpiece can be realized, and the guide pillars 8 are used for guiding;

[0041] As Figure 1 , Figure 3 , Figures 4 - 7 , Figure 12As shown in the figure, a feeding mechanism is provided at one end of the top of the frame 1. The feeding mechanism includes a storage box 4 which is arranged at one end of the lower die base 9 and is used for stacking and storing workpieces. A first through groove 36 corresponding to the upper end of the female die 5 is arranged on the lower side surface of the storage box 4.

And the length of the driving plate 15 is greater than the length of the first pushing plate 16. And it is configured that after the top of the demoulding plate 12 is flush with the upper end of the female die 5, the workpiece pushed by the first pushing plate 16 contacts the workpiece after being processed at the top of the demoulding plate 12.

[0043] As Figures 8 - 12As shown in the figure, in order to ensure the positioning accuracy of the workpiece, a positioning component is further provided. The positioning component includes a fixed shell 32 fixedly arranged on the side of the female mold 5 away from the storage bin 4. A stop plate 31 for blocking the workpiece on the top of the female mold 5 is vertically movably connected inside the fixed shell 32. A first floating frame 26 is arranged at the bottom of the fixed shell 32, and the upper end of the first floating frame 26 extends into the inside of the fixed shell 32 and is fixedly connected to the bottom of the stop plate 31. The first floating frame 26 is movably and guidingly matched with the fixed shell 32. A first roller 24 corresponding to the driving plate 15 is rotatably connected to the lower end of the first floating frame 26. A second spring 28 is vertically arranged between the bottom wall of the first floating frame 26 and the fixed shell 32. A limiting block 41 is fixedly arranged on the inner wall of the end of the first through groove 36 away from the female mold 5. A limiting groove 21 is arranged on the first pushing plate 16, and the limiting block 41 is slidably matched with the limiting groove 21. It is configured that when the limiting block 41 contacts the inner wall of the end of the limiting groove 21 away from the female mold 5, the workpiece is just completely pushed to the top of the female mold 5, and the end of the workpiece away from the first pushing plate 16 just contacts the side wall of the stop plate 31.

[0044] As Figures 8 - 11 shown, in order to ensure that the processed workpiece is completely pushed away from the female mold 5, a blanking component is arranged at the end of the female mold 5 away from the storage bin 4. The blanking component includes a hidden groove 30 arranged at the end of the female mold 5 away from the storage bin 4. A second pushing plate 23 for pushing the processed workpiece to displace is movably connected to the hidden groove 30. A guide groove 29 is obliquely arranged on the side wall of the second pushing plate 23. A guide shaft 34 corresponding to the guide groove 29 is arranged on the side wall of the first floating frame 26. The end of the guide shaft 34 away from the first floating frame 26 is movably and guidingly matched with the guide groove 29. It is configured that when the first floating frame 26 displaces upward, the second pushing plate 23 displaces in the direction away from the storage bin 4. In order to enable the driving plate 15 to continue to displace when the first pushing plate 16 does not move, a telescopic component is arranged between the connecting plate 18 and the first pushing plate 16. The telescopic component includes a guide hole 22 arranged at the end of the first pushing plate 16 close to the connecting plate 18. A guide rod 19 is movably connected to the guide hole 22. A first spring 20 is sleeved outside the guide rod 19, and the end of the guide rod 19 away from the first pushing plate 16 is fixed on the side wall of the connecting plate 18. The first spring 20 is located between the side wall of the connecting plate 18 and the end of the first pushing plate 16.

[0045] As Figure 7 、 Figures 12 - 15As shown in the figure, a separating and blanking mechanism is arranged on the storage bin 4. The separating and blanking mechanism includes vertical shafts 37 rotatably arranged at the front and rear ends of the storage bin 4, and the vertical shafts 37 are vertically arranged. Support plates 42 for supporting workpieces are uniformly arranged on the vertical shafts 37 along the height direction, and the support plates 42 are semi-circular. The support plates 42 on the same vertical shaft 37 are divided into two groups, the two groups of support plates 42 are arranged at intervals, and the orientations of the two groups of support plates 42 are opposite. Second through grooves 43 corresponding to the vertical shafts 37 are symmetrically arranged on the front and rear sides of the storage bin 4. One end of the support plate 42 can extend to the inside of the storage bin 4 through the second through groove 43. Synchronous wheels 40 are fixedly arranged on the outer sides of the lower ends of the vertical shafts 37. Synchronous belts 38 are commonly arranged on the two synchronous wheels 40 on the same side. A gear 39 is fixedly arranged at the bottom of the vertical shaft 37 far from the female die 5. A rack 17 is arranged on the side of the traction arm 6 close to the storage bin 4, and the rack 17 is intermittently engaged with the gear 39. When the rack 17 and the gear 39 are engaged once, the vertical shaft 37 can rotate 180 degrees. In order to further reduce the wear of the workpiece, a third roller 44 protruding from the top of the support plate 42 and used for rolling cooperation with the bottom of the workpiece is rotatably connected to the inner side of the upper end of the support plate 42.

[0046] During use, the workpieces of the to-be-processed plates or sheets are placed on the support plates 42 in the storage bin 4 for support. At this time, the other group of vertical shafts 37 on the vertical shafts 37 face outwards. When the oil cylinder 3 drives the upper die holder 7 to move downwards, under the action of the connecting rod 13, the whole of the traction arm 6, the driving plate 15, and the first pusher plate 16 displaces in the direction away from the female die 5. At this time, during the engagement of the rack 17 and the gear 39, all the workpieces fall a certain distance, and the falling distance is the distance between the two support plates 42, and the lowermost workpiece will fall to the bottom of the inner cavity of the storage bin 4. When the upper die holder 7 rises, the whole of the traction arm 6, the driving plate 15, and the first pusher plate 16 approaches the female die 5. At this time, the first pusher plate 16 pushes the lowermost workpiece towards the top of the female die 5. At this time, during the engagement of the rack 17 and the gear 39, all the workpieces fall a certain distance again, and the lowermost workpiece waits to fall to the bottom of the inner cavity of the storage bin 4 subsequently;

[0047] Specifically, when the traction arm 6, the driving plate 15, and the first pusher plate 16 are displaced towards the direction of the female die 5 as a whole, the first pusher plate 16 gradually pushes the lowermost workpiece to the top of the female die 5. The driving plate 15 will contact the second roller 27, and the second roller 27 climbs uphill, driving the second floating frame 33 to rise. The third spring 35 is compressed, and the stripper plate 12 is driven by the second floating frame 33 to rise. The stripper plate 12 can eject the processed workpiece from the inner cavity of the female die 5. When the second roller 27 is at the topmost part of the driving plate 15, the top of the stripper plate 12 is flush with the upper end of the female die 5. Subsequently, the workpiece pushed by the first pusher plate 16 contacts the processed workpiece at the top of the stripper plate 12 and is then gradually pushed down. When the driving plate 15 is displaced to a certain extent, it will contact the first roller 24. At this time, the first roller 24 climbs uphill, and the first floating frame 26 drives the stop plate 31 to rise. The second spring 28 is compressed. When the upper end of the stop plate 31 is higher than the upper end of the female die 5, the workpiece to be processed can be blocked. At this time, the first pusher plate 16 is displaced to the limit distance, and the workpiece is in place. At this time, the limit block 41 is located at the end of the limit groove 21 away from the female die 5, thereby blocking the first pusher plate 16. One end of the processed workpiece pushed down will overlap on one end of the female die 5. At this time, the traction arm 6 is continuously driven to displace, and then the connecting plate 18 is driven by the driving plate 15 to continue to displace. The first spring 20 is compressed, the first pusher plate 16 remains stationary, the first floating frame 26 continues to climb uphill, and the guide shaft 34 drives the second pusher plate 23 to continue to move outwards under the action of the guide groove 29. Thus, the second pusher plate 23 completely pushes away the processed workpiece overlapping on one end of the female die 5. Subsequently, the oil cylinder 3 drives the upper die holder 7 to move downwards, and then the punch 10 cooperates with the female die 5 to perform stamping, and the guide pillar 8 conducts guiding. Moreover, when the upper die holder 7 moves downwards, the driving plate 15, the first pusher plate 16, and the traction arm 6 are reset as a whole, and the stripper plate 12 and the stop plate 31 will all reset and fall before stamping. After resetting, it waits for subsequent feeding and processing. In this cycle, the device can realize automatic feeding, discharging, positioning, demoulding, etc. by using the lifting action power of the upper die holder 7. The structure is compact, the precision is high, the working efficiency is improved, the manual participation amount is reduced, and the safety is also increased.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
