The top of the mould plate 7 is provided with a mould groove 8, and the sphere at one end of the blank 9 can be placed in the mould groove 8. When the output shaft of the second hydraulic cylinder 10 drives the pressing die plate 12 to move downward, the pressing die plate 12 cooperates with the mould plate 7 to complete the flattening operation of the sphere at one end of the blank 9. Through the two flattening structures, the flattening of the spheres at the two ends of the blank 9 can be realized.

[0042] With reference to Figure 2 、 Figure 4 、 Figure 5 And Figure 6The mechanism further comprises a closing plate 23 sliding through the die plate 7. On the inner wall of the top of the gantry 3, two rotating rods 21 are rotatably connected. Two sets of punching structures are further arranged in the gantry 3, for punching the flattened ball. The punching structure comprises a connecting plate 15 sleeved on the outer wall of the rotating rod 21, and the output shaft of the second hydraulic cylinder 10 is fixedly penetrated through the connecting plate 15. The outer wall of the rotating rod 21 is slidingly connected with a first synchronous wheel 16 through a sliding groove and a sliding block, and the first synchronous wheel 16 is rotatable on the bottom of the connecting plate 15. The outer wall of the fixed column 11 is fixedly sleeved with a second synchronous wheel 17, and the second synchronous wheel 17 is drivingly connected with the first synchronous wheel 16 through a synchronous belt. The fixed column 11 is fixedly provided with a fixed plate 13 away from the pressing die plate 12, and the cooperation of the first synchronous wheel 16, the connecting plate 15 and the synchronous belt is used for direction switching of the pressing die plate 12 and the fixed plate 13.

The top of the closing plate 23 is flush with the inner wall of the bottom of the die groove 8, which facilitates the cooperation of the die plate 7 and the pressing die plate 12 for punching operation. One end of the closing plate 23 slidingly extends to one side of the die plate 7, and a connecting rod 24 is fixedly connected at the bottom of the closing plate 23. The bottom end of the connecting rod 24 is rotatably connected with one side of the top of the connecting rod 25. In this way, when the rotating rod 21 rotates, it can drive the pressing die plate 12 and the fixed plate 13 to switch direction through the cooperation of the first synchronous wheel 16, the second synchronous wheel 17 and the synchronous belt, facilitating the subsequent punching of the punching head 20. At the same time, the rotating rod 21 will also drive the closing plate 23 to move outward through the cooperation of the disc 47, the fixed pin 26 and the connecting rod 25, thereby releasing the closing of the clearance hole 22. At this time, the fixed plate 13 and the pressing plate 14 are driven downward by the second hydraulic cylinder 10, and the pressing plate 14 is pressed against one end of the blank 9 under the action of the spring 19, thereby ensuring the stability. With the continuous downward movement of the fixed plate 13, the punching of the blank 9 at one end is completed through the cooperation of the punching head 20 and the clearance hole 22.

[0044] Specifically, when the second hydraulic cylinder 10 drives the fixed plate 13 and the pressing plate 14 to move downward to perform punching, the pressing plate 14 presses one end of the blank 9 under the action of the spring 19 to ensure its stability. As the fixed plate 13 continues to move downward, the punch head 20 cooperates with the clearance hole 22 to complete the punching of one end of the blank 9.

[0045] Reference Figure 3 and Figure 6- Figure 8 To automatically transport subsequent blanks 9 to the lower mold 2, the mechanism also includes a feeding mechanism. This mechanism is located on the outer wall of the lower mold 2 and comprises two rotating disks 33 that rotate on opposite sides of the lower mold 2. Multiple levers 34 are fixedly mounted on the outer walls of each rotating disk 33 to move the blanks 9 for transport. A placement plate 37 is fixed to the side of the lower mold 2 adjacent to the rotating disks 33, which is used to place the blanks 9 to be processed. As the rotating disks 33 rotate, the levers 34 move the blanks 9 on the placement plate 37, transporting them to the lower mold 2 for processing. The feeding mechanism comprises two racks 27, whose ends, facing away from each other, slide into the corresponding mold plate 7 and are fixedly connected to one end of the corresponding closing plate 23. Two base plates 28 are fixedly connected to the tops of the two support plates 6. A rotating shaft 29 is rotatably connected between the two base plates 28. A one-way bearing 30 is mounted on the outer wall of the rotating shaft 29. The inner ring of the one-way bearing 30 mates with the outer wall of the rotating shaft 29, while its outer ring is fixedly mounted with a spur gear 31. The spur gear 31 and the one-way bearing 30 drive the rotating shaft 29 in one-way rotation, while the spur gear 31 meshes with the rack 27. A first bevel gear 32 is also fixedly mounted on the outer wall of the rotating shaft 29. Furthermore, a fixed rod 35 is fixedly connected to the side of each rotating disk 33 facing away from each other. A second bevel gear 36 is fixedly connected to the end facing away from each other of each fixed rod 35, and the second bevel gear 36 meshes with the corresponding first bevel gear 32. A gap is provided between adjacent shifting rods 34 to facilitate the movement of the blank 9.

[0046] Specifically, after the blank 9 is bent, the upper mold 5 moves up and resets. Then, the motor drives the rotating rod 21 to rotate, completing the direction reversal of the fixed plate 13. At this time, the rotating rod 21 drives the closing plate 23 and the rack 27 to move toward the middle through the cooperation of the disc 47, the connecting rod 25 and the fixed pin 26. The closing plate 23 closes the clearance hole 22 to facilitate the subsequent stamping of the blank 9. The rack 27 drives the spur gear 31 to rotate, and the spur gear 31 drives the rotating shaft 29 to rotate in one direction through the one-way bearing 30. The rotating shaft 29 drives the second bevel gear 36 and the rotating disk 33 to rotate through the cooperation of the first bevel gear 32 and the second bevel gear 36. The shifting rod 34 can push the subsequent blank 9 on the placement plate 37 toward the lower mold 2 to complete the loading operation.

[0047] Reference Figure 5In order to better clamp the blank 9, a plurality of guide rods 18 are slid through the fixed plate 13. The bottom ends of the plurality of guide rods 18 are fixedly connected to the same pressing plate 14. A plurality of springs 19 are fixedly connected between the fixed plate 13 and the pressing plate 14, and the plurality of springs 19 are sleeved on the outer walls of the corresponding guide rods 18. The cooperation of the guide rods 18 and the springs 19 is used to clamp the blank 9. At the same time, the bottom end of the stamping head 20 slides through the pressing plate 14.

[0048] With reference to Figure 9 The top of the lower die 2 is designed with two limiting grooves 40, which are matched in shape and size with the blank 9, and are used to accurately limit the blank 9 when it is placed on the top of the lower die 2, so as to ensure that the blank 9 does not deviate during processing. On both sides of the top of the lower die 2, limiting plates 38 are also fixed, which can further limit the blank 9 when it is conveyed to the lower die 2, so as to ensure that the blank 9 can be accurately placed in the limiting groove 40.

[0049] With reference to Figure 9 The outer wall of the upper die 5 is provided with a first track groove 39, and the inner wall of the lower die 2 is provided with a second track groove 41 matched with the first track groove 39. When the output shaft of the first hydraulic cylinder 4 pushes the upper die 5 to move downward to bend the blank 9, the cooperation of the second track groove 41 and the first track groove 39 can clamp and limit the blank 9 during bending, so as to avoid the blank 9 from being separated between the upper die 5 and the lower die 2.

[0050] With reference to Figure 9 In addition, guide grooves 42 are also provided on the side where the two limiting grooves 40 are close to each other. The two guide grooves 42 are communicated with the second track groove 41, and their function is to guide the blank 9 during bending to ensure that the blank 9 can be bent according to the predetermined track.

[0051] With reference to Figure 9 The top of the placing plate 37 is designed with an inclined surface 43, which makes the plurality of blanks 9 located in the placing plate 37 move automatically downward to the direction of the lower die 2 under the action of gravity, so as to realize automatic feeding of the blanks.

The lower side of the heat preservation asbestos board 44 is rotatably connected with a closing asbestos board 45, which is close to the side of the placing plate 37 away from the lower die 2. The cooperation of the heat preservation asbestos board 44 and the closing asbestos board 45 can keep the temperature of the multiple blanks 9, avoiding the heat dissipation of the blanks 9, which can reduce the temperature and affect the later processing. At the bottom of the heat preservation asbestos board 44, multiple carbon fiber heating sheets 46 are fixed. These carbon fiber heating sheets 46 can heat the multiple blanks 9, ensuring that the temperature of the blanks 9 is within the appropriate range, so as to ensure that the later processing can be carried out smoothly.

[0054] Specifically, first, the carbon fiber heating sheets 46 heat the blank 9, and then the blank 9 is moved into the limiting groove 40 of the lower die 2. Then, the first hydraulic cylinder 4 drives the upper die 5 to move downward to bend the blank 9. In the bending process, the cooperation of the guide groove 42, the second track groove 41 and the first track groove 39 can ensure that the blank 9 is bent according to the predetermined track, and finally forms a U-shaped hanging ring.

The rotating rod 21 drives the closing plate 23 to move outward through the cooperation of the disc 47, the fixed pin 26 and the connecting rod 25, which releases the closing of the relief hole 22. Then, the second hydraulic cylinder 10 drives the fixed plate 13 and the pressing plate 14 to move downward. The pressing plate 14 presses one end of the blank 9 under the action of the spring 19, which ensures the stability.
