DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0031] like Figure 1-Figure 5 As shown, the technical solution adopted by the present invention is as follows: a deflection rounding production line, comprising a base 1. The base 1 is L-shaped. An uncoiler 2, a leveler 4, a deflection machine 5, and a support frame 6 for winding the coil are arranged from left to right on the upper end of the base 1. A clamping mechanism is provided on the uncoiler 2 to achieve pressure holding of the coil. The uncoiler 2 is used to unwind the coil. The leveler 4 is used to level and feed the coil. A slide rail is provided on the left side of the upper end of the base 1. A pedestal car 3 is slidably mounted on the slide rail, and the pedestal car 3 is arranged opposite to the uncoiler 2. It is used to place the coil.

[0032] The support frame 6 is in an inverted concave shape. The support frame 6 consists of two fixed plates and a cross plate. The cross plate is fixedly connected to the upper ends of the two fixed plates. A upper module 9 is slidably connected between the two fixed plates of the support frame 6. A connecting plate 23 is fixedly connected to the bottom end of the upper module 9. A first mold is provided on the connecting plate 23. A lower module 12 is fixedly connected between the two fixed plates of the support frame 6. A second mold is provided at the upper end of the lower module 12. The first mold and the second mold are arranged opposite to each other, and the first mold and the second mold cooperate to punch and cut the sheet material.

[0033] In this embodiment, the first mold is the first female mold 22, and the second mold is the first male mold.

[0034] The first female mold 22 is fixedly arranged at the bottom end of the connecting plate 23. The first male mold is fixedly arranged at the upper end of the lower module 12. The first female mold 22 and the first male mold are directly opposite to each other, and the first female mold 22 and the first male mold cooperate to punch and cut the flattened sheet material. A first telescopic rod 13 is fixedly installed at the bottom end of the cross plate of the support frame 6, and the telescopic end of the first telescopic rod 13 is fixedly connected to the upper end surface of the upper module 9.

[0035] Guide rods 11 are fixedly arranged at the four corners of the upper end of the lower module 12. The guide rods 11 are slidably connected to the upper module 9 and have a guiding effect on the upper module 9.

[0036] A second conveying device 8 is arranged on the front side of the support frame 6. A blanking chute 14 is arranged between the second conveying device 8 and the support frame 6. The punched materials are transported onto the second conveying device 8 through the blanking chute 14, and are conveyed to another device through the second conveying device 8. A first conveying device 7 is arranged on the right side of the support frame 6. The first conveying device 7 is used for conveying waste materials.

[0037] One end of the blanking chute 14 is between the first female mold 22 and the first male mold, and the end of the blanking chute 14 far from the support frame 6 slopes downward, which is convenient for conveying the sheet material on the first female mold 22 onto the second conveying device 8.

[0038] First chutes 15 are provided on both sides of the second conveying device 8. Sliders 16 are slidably arranged in the first chutes 15. The blanking chute 14 is fixedly connected between the two sliders 16. A second telescopic rod 18 is fixedly installed on one side of the lower module 12, and the telescopic end of the second telescopic rod 18 is fixedly connected to the blanking chute 14. The first telescopic rod 13 and the second telescopic rod 18 are both electric telescopic rods.

[0039] A cutting knife 10 is fixedly installed at the bottom end of the side of the upper module 9 close to the first conveying device 7 for cutting the waste materials. The cut waste materials fall onto the first conveying device 7 and are conveyed away by the first conveying device 7.

[0040] A transmission mechanism is provided on the upper module 9, which causes the plate stuck in the first die 22 to fall off. The transmission mechanism includes a fixing rod 17. A first groove 19 is provided at the bottom end of the upper module 9. A plurality of first through holes 21 are evenly provided on the connecting plate 23 along the circumferential direction, and the first groove 19 is connected to the interior of the first die 22 through the first through holes 21. A first air hole 20 is provided on the upper module 9, and the first air hole 20 is L-shaped. The first air hole 20 is connected to the first groove 19. The fixing rod 17 is fixedly provided at the bottom end of the upper horizontal plate of the support frame 6, and one end of the fixing rod 17 is fixedly connected to a piston 24. The piston 24 is sealed and slidably matched with the first air hole 20. The fixing rod 17 is slidably connected to the upper module 9.

[0041] In summary, in the initial state, the piston 24 is located in the first air hole 20. One end of the blanking chute 14 is located between the first punch and the first die 22.

[0042] The coil is placed on the trolley 3, which then moves the coil toward the uncoiler 2. As the trolley 3 and the coil move below the uncoiler 2, the clamping mechanism on the uncoiler 2 secures the coil. One end of the coil passes through the leveler 4 and the deflector 5, then is placed between the upper module 9 and the lower module 12.

[0043] The second telescopic rod 18 is started, and the second telescopic rod 18 moves the unloading chute 14 away from the support frame 6. The unloading chute 14 moves with the slider 16 in the first chute 15. When the unloading chute 14 is away from the support frame 6, the second telescopic rod 18 stops.

[0044] The first telescopic rod 13 is activated, causing the upper die block 9 to move downward. This movement, along with the connecting plate 23 and the first die 22, causes the piston 24 to move upward within the first air hole 20 relative to the upper die block 9. After the first die 22 has moved a certain distance, the piston 24 disengages from the upper die block 9. The first die 22 continues to approach the first punch. When the first die 22 contacts the sheet material, the first punch and the first die 22 cooperate to punch and cut the sheet material. The cut sheet material is then trapped within the first die 22.

[0045] At the same time, the upper module 9 moves downward with the cutting knife 10, and the cutting knife 10 moves downward to contact the plate and cuts the discarded plate. The cut waste falls onto the first transmission device 7 and is transported away by the first transmission device 7.

[0046] After stamping is complete, the first telescopic rod 13 is activated, causing the upper die block 9 to move upward, carrying the connecting plate 23, the first die 22, and the cutting blade 10. When the upper die block 9 and the first die 22 have risen to a certain height, the second telescopic rod 18 is retracted, causing the unloading chute 14 to move toward the support frame 6. When one end of the unloading chute 14 is below the first die 22, the second telescopic rod 18 stops.

[0047] At the same time, piston 24 moves downward within first air hole 20, squeezing the air within. The air in first air hole 20 is then compressed through first groove 19 and first through-hole 21 and enters first die 22, causing the sheet material within first die 22 to fall out. When the sheet material falls out, the discharge chute 14 moves below first die 22, and the fallen sheet material falls onto the discharge chute 14. Because the discharge chute 14 is tilted, the sheet material slides onto second conveyor 8, where it is transported to the next device. Example 2

[0048] like Figures 6-10 The eccentric rounding production line shown here only introduces the differences from Example 1, and the other identical parts are not introduced in detail here.

[0049] In this embodiment, the first mold is the second punch 33, and the second mold is the second die 31. A third chute 32 is defined within the connecting plate 23, within which a slide 34 is positioned for sealing and sliding engagement. A spring 35 is fixedly positioned within the third chute 32, one end of which is fixedly connected to the slide 34, while the other end of the spring 35 is fixedly connected to the inner wall of the third chute 32. The second punch 33 is fixedly positioned at the bottom of the slide 34. The second die 31 is fixedly positioned at the top of the lower die block 12. The second punch 33 and the second die 31 cooperate to punch and cut the sheet metal.

[0050] A second groove 26 is defined within the upper die block 9. Several air holes 36 are defined on both the slide plate 34 and the second punch 33, corresponding to the air holes 36 on the slide plate 34 and the second punch 33. The air holes 36 communicate with the third chute 32. Several second through holes 25 are evenly defined on the bottom wall of the second groove 26, connecting the second groove 26 to the third chute 32 via the second through holes 25.

[0051] The transmission mechanism includes a plurality of slide rods 30. There are four slide rods 30. Second slide grooves 29 are provided at the four corners of the lower module 12. The slide rods 30 are sealed and slidably arranged in the corresponding second slide grooves 29. The end of the slide rod 30 away from the lower module 12 is fixedly connected to the upper module 9. A connecting hole 28 connected to the second slide groove 29 is provided on the slide rod 30. The connecting hole 28 is arranged vertically. Four L-shaped second air holes 27 are provided on the upper module 9, and the second air holes 27 are arranged in a circular array along the second groove 26. The second groove 26 is connected to the connecting hole 28 through the second air holes 27. Four exhaust holes 37 connected to the outside are provided on the lower module 12, and the exhaust holes 37 are connected to the corresponding second slide grooves 29. The bottom surface of the exhaust hole 37 is located in the middle and upper part of the second slide groove 29.

[0052] In summary, in the initial state, the bottom end of the slide rod 30 is located below the bottom surface of the exhaust hole 37 , and the second slide groove 29 is not connected to the exhaust hole 37 .

[0053] The first telescopic rod 13 moves the upper die block 9 downward, carrying the second punch 33, connecting plate 23, and cutting blade 10. The second punch 33 cooperates with the second die 31 to punch and cut the sheet material. During this process, the second punch 33 first contacts the sheet material and cooperates with the second die 31 to deform the sheet material. As the second punch 33 continues to move downward, it drives the slide 34 upward within the third chute 32, compressing the spring 35. When the spring 35 is compressed to a certain degree, the second punch 33 and the second die 31 cooperate to cut the sheet material.

[0054] At the same time, the upper module 9 moves downward with the slide rod 30 in the second slide groove 29. The air in the second slide groove 29 enters the second air hole 27 of the upper module 9 through the connecting hole 28, and then enters the second punch 33 through the second groove 26, the second through hole 25, the third slide groove 32, and the blowing hole 36, thereby cooling the second punch 33 to prevent the second punch 33 from increasing in temperature due to long-term work, thereby affecting the quality of product stamping and cutting.

[0055] After punching and cutting, the upper die 9, carrying the connecting plate 23, the second punch 33, and the cutting blade 10, moves upward. The second punch 33, acting under the action of the spring 35, contacts the sheet. Simultaneously, the upper die 9, carrying the slide bar 30, moves upward within the second chute 29. The space within the second chute 29 expands, allowing air between the sheet and the second punch 33 to enter the second chute 29 through the air holes 36 and the second groove 26, thereby attracting the sheet to the second punch 33.

[0056] When the upper die block 9 rises to a certain height, the unloading chute 14 moves to the bottom of the second punch 33. When the unloading chute 14 moves to the bottom of the second punch 33, the bottom surface of the slide bar 30 is located above the exhaust hole 37, which is connected to the second chute 29. The air in the second chute 29 is discharged through the exhaust hole 37, and the suction force between the second punch 33 and the plate is reduced. The plate adsorbed on the second punch 33 falls onto the unloading chute 14 and is finally transported to the next equipment by the second conveyor 8.

[0057] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
