Description

Technical Field

[0001] This invention relates to the field of blanking technology, and in particular to a blanking device for partitions used in the production of automotive exhaust pipe mufflers. Background Technology

[0002] The baffles in a car exhaust muffler are a key component for noise reduction. They are typically located inside the muffler and work by dividing the muffler into multiple chambers. These baffles help to alter the flow path of exhaust gases, reducing airflow velocity and thus decreasing noise.

[0003] The punching operation of the muffler baffle of the automobile exhaust pipe is a crucial step in the manufacturing process. Its purpose is to precisely cut and shape the baffle. The punching process uses a hydraulic or mechanical press to apply great pressure so that the die cuts through the sheet metal. This process can efficiently and quickly cut the baffle of the required shape and size from the metal sheet while ensuring smooth edges without burrs, thus reducing subsequent processing steps.

[0004] In the traditional partition punching process, operators need to manually complete a series of actions such as feeding, unloading, and placing the punched partitions into the collection box. This is not only labor-intensive and inefficient, but also poses significant safety hazards. Especially during high-speed operation of the equipment, a slight mistake can lead to workplace injuries. Because the punching process requires applying great pressure to the partitions, some partitions may adhere to the piston rod or die surface due to the force and cannot be immediately removed. When these partitions fall due to gravity or subsequent actions, it can easily cause material handling chaos and even affect the normal operation of subsequent processes, reducing overall production efficiency and product consistency.

Detailed Implementation

[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0032] A baffle punching device for manufacturing automotive exhaust pipe mufflers, such as Figures 1-12As shown, the device includes a table 1, a support 2, a punching system 3, a fixed table 6, a blanking frame 34, a fixed plate 35, a punching slide 4, a punching rod 5, a guide plate 7, a first connecting rod 12, a second connecting rod 13, a first spring 14, a second spring 15, a connecting block 16, a top block 161, an arc-shaped push plate 17, and an arc-shaped limiting block 18. The support 2, the punching system 3, the fixed table 6, and the blanking frame 34 are connected to the table 1. The fixed table 6 is fixedly connected to the blanking frame 34. The punching slide 4 is slidably connected to the punching system 3. The punching rod 5 is fixedly connected to the bottom of the punching slide 4. The fixed plate 35 is fixedly connected to the top of the blanking frame 34 and communicates with the blanking frame 34. The guide plate 7, flush with the fixed plate 35, is fixedly connected to the top of the fixed table 6. Two first connecting rods 12 are rotatably connected to the punching slide 4, and each first connecting rod 12 is slidably connected to a second connecting rod 13. A first spring 14 is fixedly connected between the first connecting rod 12 and the second connecting rod 13. Sliding holes 71 are opened on both the front and rear sides of the guide plate 7. The second connecting rod 13 is slidably and rotatably connected to the guide plate 7 through the sliding holes 71. A second spring 15 is fixedly connected between the second connecting rod 13 and the guide plate 7. A connecting block 16 is fixedly connected between the two second connecting rods 13. The connecting block 16 is slidably connected to the guide plate 7 through the sliding holes 71. An arc-shaped push plate 17 is fixedly connected to the side of the connecting block 16 closest to the fixed plate 35. An arc-shaped limiting block 18 aligned with the discharge hole 91 is fixedly connected to the guide plate 7. The arc-shaped limiting block 18 and the arc-shaped push plate 17 are staggered vertically to avoid collision between the arc-shaped push plate 17 and the arc-shaped limiting block 18 when the arc-shaped push plate 17 moves to the right. At least two top blocks 161 are fixedly connected to the side of the connecting block 16 away from the arc-shaped push plate 17. Each top block 161 has an inclined surface.

[0033] Initially, partitions are placed on each workstation plate 9, positioned between the workstation plate 9, the limiting rod 10, and the limiting plate 11. The punching rod 5 is away from the fixed plate 35. The first spring 14 and the second spring 15 are in their natural state. The arc-shaped push plate 17 is positioned above the fixed plate 35. The left workstation plate 9 is close to the fixed plate 35, while the right workstation plate 9 is away from the fixed plate 35. During partition punching, the partition on the left workstation plate 9 falls onto the guide plate 7 through the discharge hole 91, and the punching system 3 drives the punching. The sliding plate 4 moves downward, causing the first connecting rod 12 and the second connecting rod 13 to rotate. The first connecting rod 12 slides into the second connecting rod 13, and the second connecting rod 13 slides away from the fixed plate 35 along the sliding hole 71. The first spring 14 and the second spring 15 are both compressed. The second connecting rod 13 causes the connecting block 16 and the arc-shaped push plate 17 to move away from the fixed plate 35, so that the top block 161 lifts the partition. During the process, the partition moves along the inclined surface of the top block 161 into the arc-shaped push plate 17. The arc-shaped limiting block 18 limits the partition to ensure that the partition can move normally along the inclined surface of the top block 161. When the partition is punched, the punching slide 4 moves upward. The upward movement of the punching slide 4 drives the first connecting rod 12 and the second connecting rod 13 to reverse. The first spring 14 returns to its original state, causing the first connecting rod 12 to slide away from the second connecting rod 13. The second spring 15 returns to its original state, causing the second connecting rod 13 to slide along the sliding hole 71 and approach the fixed plate 35. The second connecting rod 13 drives the connecting block 16 and the arc-shaped push plate 17 to move onto the fixed plate 35. Thus, the partition is pushed to the top of the fixed plate 35 by the arc-shaped push plate 17, thereby completing one feeding of the partition. Repeating the above operation can realize multiple automatic feedings of the partition without manual feeding, reducing the labor intensity and labor costs of workers, reducing the safety hazards caused by operators working near the punching device, and improving the safety of partition punching.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9As shown, it also includes a rotating shaft 8, a workstation disk 9, a limiting rod 10, a limiting plate 11, a gear 19, an electric slide rail 20, and a rack 21. The rotating shaft 8 is rotatably connected to the guide plate 7 and passes through the guide plate 7. Two workstation disks 9 are fixedly connected to the outer wall of the rotating shaft 8 at even intervals along the circumference. Each workstation disk 9 has a discharge hole 91. At least four limiting rods 10 are fixedly connected to each workstation disk 9. A limiting plate 11 is fixedly connected between the ends of the limiting rods 10 away from the workstation disk 9. A gear 19 is fixedly connected to the bottom of the rotating shaft 8. An electric slide rail 20 is fixedly connected to the bottom of the guide plate 7. A rack 21 is fixedly connected to the slider of the electric slide rail 20. The rack 21 is slidably connected to the guide plate 7, and the gear 19 meshes with the rack 21.

[0035] When there are no partitions on the left workstation 9, the slider of the electric slide rail 20 drives the rack 21 to move. Under the meshing action of the gear 19 and the rack 21, the gear 19 rotates half a turn. The rotation of the gear 19 drives the two workstations 9 to rotate 180 degrees along the axis of the rotating shaft 8. The left workstation 9 rotates away from the fixed plate 35 and puts the partition into the left workstation 9. The right workstation 9 rotates closer to the fixed plate 35 and feeds the partition in the right workstation 9. When there are no partitions in the right workstation 9, the slider of the electric slide rail 20 drives the rack 21 to move in the opposite direction, causing the gear 19 to reverse half a turn. The reverse rotation of the gear 19 drives the two workstations 9 to reverse 180 degrees. This enables the switching between the two workstations 9 and realizes the automatic replenishment of partitions, ensuring the efficiency of continuous production and reducing downtime.

[0036] like Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, it also includes a movable plate 22, a stop block 23, a third spring 24, and an extrusion assembly. Two through slots 92 are opened in the workstation plate 9, and the discharge hole 91 communicates with the through slots 92. Two movable plates 22 are slidably connected in the workstation plate 9, and the movable plates 22 penetrate the workstation plate 9. Stop blocks 23 are slidably connected in the through slots 92, and the stop blocks 23 are fixedly connected to the movable plates 22. A third spring 24 is fixedly connected between the stop blocks 23 and the through slots 92. An extrusion assembly for extruding the movable plates 22 is connected on the guide plate 7.

[0037] like Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the extrusion assembly includes a fixed block 25, a wedge-shaped pressure plate 26, a fourth spring 261, a fixed column 27, a fifth spring 28, and an inclined block 29. Two fixed blocks 25 are fixedly connected to the front side of the workstation plate 9, and two wedge-shaped pressure plates 26 are slidably connected to the front side of the guide plate 7. The wedge-shaped pressure plates 26 are slidably connected to the fixed blocks 25. The fourth spring 261 is fixedly connected between the wedge-shaped pressure plates 26 and the fixed blocks 25. The moving plate 22 is in contact with the inclined surface of the wedge-shaped pressure plates 26. Inclined grooves 93 are opened on both the front and rear sides of the workstation plate 9. Fixed columns 27 are fixedly connected to the top of the guide plate 7 on both the front and rear sides. The fixed columns 27 are close to the fixed plate 35. Inclined blocks 29 are slidably connected to the fixed columns 27. The fifth spring 28 is fixedly connected between the inclined blocks 29 and the fixed columns 27. The inclined blocks 29 are aligned with the inclined grooves 93.

[0038] When the third spring 24 is in its natural state, the stop block 23 extends from the through slot 92, and the partition falls between the tops of the two stop blocks 23. The stop blocks 23 block the partition, preventing it from falling onto the guide plate 7 through the discharge hole 91. As the left station plate 9 rotates 180 degrees towards the fixed plate 35, the front wedge-shaped pressure plate 26 presses against the inclined surface of the rear inclined block 29, causing it to slide downwards along the rear fixed post 17. The inclined groove 93 of the left station plate 9 then presses against the rear inclined block 29, causing it to slide downwards again along the rear fixed post 27. The rear fifth spring 28 is compressed, enabling... To prevent the rear inclined block 29 from obstructing the rotation of the left workstation plate 9, when the left workstation plate 9 rotates 180 degrees and approaches the fixed plate 35, the fifth spring 28 returns to its original state, causing the rear inclined block 29 to slide upward along the rear fixed column 27. The non-inclined portion of the front inclined block 29 presses against the wedge-shaped pressure plate 26, causing the left wedge-shaped pressure plate 26 to slide along the rear fixed frame 25 and approach the left workstation plate 9. The fourth spring 261 is compressed, and the left wedge-shaped pressure plate 26 simultaneously presses against the two left movable plates 22, causing the two left movable plates 22 to slide along the inclination of the left wedge-shaped pressure plate 26. As the surface moves away from the left feed hole 91, the left stop blocks 23 slide into the through groove 92, compressing the third spring 24. At this time, the left stop blocks 23 no longer block the partition, allowing the partition to fall normally onto the guide plate 7 from the left feed hole 91 for feeding. The stop blocks 23 in the right station plate 9 block the partition, preventing it from falling when the right station plate 9 is not in the feeding state. Only when the left station plate 9 is in the feeding state do the left stop blocks 23 retract into the through groove 92 to ensure the partition can feed normally, thereby improving feeding accuracy and stability. When the plate rotates 180 degrees away from the fixed plate 35, the rear inclined groove 93 of the left station plate 9 presses the rear inclined block 29 to move it downward. The fifth spring 28 is compressed, the two moving plates 22 on the left move away from the left wedge-shaped pressure plate 26, the third spring 24 and the fourth spring 261 return to their original state, the two moving plates 22 on the left slide close to the left discharge hole 91, the left stop block 23 extends out from the through groove 92, the left wedge-shaped pressure plate 26 moves in the opposite direction to reset, and then a partition is placed in the left station plate 9. The same principle applies when the right station plate 9 rotates 180 degrees.

[0039] like Figure 1 and Figure 9 As shown, it also includes a sixth spring 30, a circular pressure plate 31, a fixing frame 32, and a connecting rope 33. The sixth spring 30 is fixedly connected to the side of the limiting plate 11 near the workstation plate 9, and the circular pressure plate 31 is fixedly connected to the side of the sixth spring 30 away from the limiting plate 11. The circular pressure plate 31 is slidably connected to the limiting rod 10. The sixth spring 30 is fixedly connected to the circular pressure plate 31. The fixing frame 32 is fixedly connected between the front and rear brackets 2. Two connecting ropes 33 are fixedly connected to the bottom of the fixing frame 32. The connecting ropes 33 pass through the limiting plate 11, and the two connecting ropes 33 are fixedly connected to the two circular pressure plates 31 respectively.

[0040] When the left workstation plate 9 approaches the fixed plate 35, the connecting rope 33 on the left circular pressure plate 31 and the left sixth spring 30 are in their natural state. The left circular pressure plate 31 is close to the left workstation plate 9, the connecting rope 33 on the right circular pressure plate 31 is taut, and the right sixth spring 30 is compressed. The right circular pressure plate 31 is close to the right limiting plate 11. Under the elastic force of the left sixth spring 30, the left circular pressure plate 31 presses down on the partition on the left workstation plate 9, thereby preventing the partition from failing to fall smoothly from the left discharge hole 91 due to vibration or insufficient friction. This ensures that each feeding is completed accurately and improves the reliability of feeding. When a partition is placed on the side workstation 9, the connecting rope 33 on the right circular pressure plate 31 pulls the right circular pressure plate 31 upward, eliminating the need to manually lift the right circular pressure plate 31, thus facilitating the placement of the partition. When the two workstations 9 are rotated 180 degrees, the connecting rope 33 on the left circular pressure plate 31 pulls the left circular pressure plate 31, causing it to slide upward along the left limit rod 10. The connecting rope 33 on the right circular pressure plate 31 no longer pulls the right circular pressure plate 31. Under the elastic force of the sixth spring 30 on the right circular pressure plate 31, the right circular pressure plate 31 slides downward along the right limit rod 10. The same principle applies when the two workstations 9 are rotated 180 degrees.

[0041] like Figure 10 As shown, it also includes baffles 36, slide bars 37, a seventh spring 38, connecting frames 39, fixing frames 40, locking blocks 41, and an eighth spring 42. Two baffles 36 for blocking the material discharge hole 91 are slidably connected inside the fixing plate 35. Slide bars 37 are fixedly connected to the sides of the baffles 36 that are far apart from each other. The slide bars 37 are slidably connected to the fixing plate 35. A seventh spring 38 is fixedly connected between the baffles 36 and the fixing plate 35. Two connecting frames 39 are fixedly connected to the bottom of the punching slide plate 4. Fixing frames 40 are fixedly connected to the sides of the connecting frames 39 that are close to each other. Locking blocks 41 are slidably connected inside the fixing frames 40. Locking blocks 41 are mounted on... Both sides of the bottom are provided with inclined surfaces. The area of ​​the two locking blocks 41 on the side away from each other is smaller than the area on the side that is close to each other. The locking blocks 41 and the fixed frame 40 are fixedly connected by an eighth spring 42. The connecting frame 39 has a first sliding groove 391, a second sliding groove 392 and a third sliding groove 393. The sliding rod 37 and the locking blocks 41 are slidably connected to the connecting frame 39 through the first sliding groove 391, the second sliding groove 392 and the third sliding groove 393. The first sliding groove 391, the second sliding groove 392 and the third sliding groove 393 are all interconnected. The third sliding groove 393 is perpendicular to the fixed plate 35. The second sliding groove 392 is L-shaped and the first sliding groove 391 is inclined.

[0042] When the cutting slide plate 4 moves away from the fixed plate 35, the two baffles 36 are pressed tightly against each other, ensuring that the partition can complete the cutting on the fixed plate 35. The seventh spring 38 and the eighth spring 42 are in their natural state. The slide rods 37 are all located at the lower part of the third slide groove 393, and the locking blocks 41 are all located at the connection between the first slide groove 391 and the third slide groove 393. When the cutting slide plate 4 slides downward to perform cutting, the slide rods 37 slide upward along the third slide groove 393. The slide rods 37 press the lower inclined surface of the locking blocks 41, causing the locking blocks 41 to slide into the fixed frame 40. The eighth spring 42 is compressed. When the slide rods 37 are at the top of the third slide groove 393, the partition cutting is completed. When the cutting slide plate 4 moves upward, the slide rods 37 slide along the upper inclined surface of the locking blocks 41. When the slide bar 37 moves into the first slide groove 391, the eighth spring 42 is stretched, and the two baffles 36 slide away from each other. The fixed plate 35 is connected to the feeding frame 34. After the blanking is completed, the partition falls out of the feeding frame 34. After each blanking, the partition can fall into the feeding frame 34, thereby realizing automatic feeding, avoiding the safety risks caused by manual material handling, improving the automation level of this blanking device, and further improving the continuous production efficiency of the partition. The slide bar 37 then slides from the first slide groove 391 to the second slide groove 392. The eighth spring 42 returns to its original state, causing the slide bar 37 to slide from the second slide groove 392 to the third slide groove 393. The slide bar 37 then slides down to the lower part of the third slide groove 393 to reset. The two baffles 36 slide close to each other to reset.

[0043] like Figure 1 and Figure 11 As shown, it also includes a fixed tube 46, an insert rod 47, a ninth spring 48, a first solenoid valve 49, an airbag 50, a second solenoid valve 51, and a high-pressure nozzle 52. The bottom of the punching slide plate 4 is fixedly connected to two fixed tubes 46. An insert rod 47 is slidably connected inside each fixed tube 46. A ninth spring 48 is fixedly connected between the insert rod 47 and the fixed tube 46. An airbag 50 is connected to each fixed tube 46. The end of the fixed tube 46 away from the insert rod 47 is fixedly connected to the second solenoid valve 51 and the high-pressure nozzle 52. The end of the fixed tube 46 near the insert rod 47 is fixedly connected to the first solenoid valve 49. The airbags 50 are all located between the first solenoid valve 49 and the second solenoid valve 51. The high-pressure nozzles 52 are all aligned with the outer wall of the punching rod 5.

[0044] When the punching slide 4 moves away from the fixed plate 35, the ninth spring 48 is in its normal state, the insert rod 47 extends from the fixed tube 46, the first solenoid valve 49 and the second solenoid valve 51 are both open, and the airbag 50 is in its natural state. When the punching slide 4 slides downward, the second solenoid valve 51 is closed, the table surface 1 presses the insert rod 47 to extend into the fixed tube 46, the ninth spring 48 is compressed, and the air in the fixed tube 46 fills the airbag 50, causing the airbag 50 to inflate. After punching is completed, the first solenoid valve 49 is closed, and the second solenoid valve 51 is opened, allowing the air in the airbag 50 to enter the high-pressure area through the fixed tube 46. The high-pressure nozzle 52 compresses air and sprays it onto the punching rod 5. When the partition adheres to the punching rod 5, the high-pressure air can blow the partition adhered to the punching rod 5 onto the fixed plate 35, promptly removing the partition remaining on the punching rod 5, ensuring the accuracy of each punching action, and avoiding manual intervention, further improving the stability and automation of this punching device. When the punching slide plate 4 slides away from the fixed plate 35, the first solenoid valve 49 and the second solenoid valve 51 are opened, the air bag 50 returns to its original state, and the ninth spring 48 returns to its original state, causing the insertion rod 47 to slide away from the fixed tube 46.

[0045] like Figure 12 As shown, it also includes a collection frame 43, a filter plate 44 and a partition plate 45. The rear side of the table 1 is open. The double-compartment collection frame 43 is slidably connected inside the table 1. The filter plate 44 and the partition plate 45 are fixedly connected inside the table 1. The filter plate 44 is aligned with the feeding frame 34 and is inclined.

[0046] When both baffles 36 are far apart, the finished product partition falls from the feed frame 34 onto the filter plate 44. The die-cutting debris passes through the filter plate 44 and falls into one of the compartments of the feed frame 34. Thus, the debris and the finished product partition are separated by the filter plate 44. The finished product partition slides down the filter plate 44 into another compartment of the collection frame 43, thereby achieving classified collection. The partition plate 45 can prevent debris from falling into the other compartment, which is beneficial for the subsequent partition management.

[0047] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
