A cutting device for automotive airflow pipes

Abstract

This invention relates to the field of airflow pipe cutting and discloses a cutting device for automotive airflow pipes. The device includes a worktable with a feeding trough in the center and feeding troughs on both sides. A receiving structure is located below the feeding troughs within the worktable, and a feeding structure is located below the feeding troughs. Anti-deformation structures are installed along the left and right edges of the worktable. An anti-deformation rod is inserted into the airflow pipe using the anti-deformation structure. During cutting, this rod prevents deformation. In conjunction with a limiting structure, the device not only limits the airflow pipe during cutting but also, after cutting, allows the anti-deformation structure to move in the opposite direction, pulling the anti-deformation rod out of the limiting structure. This, in turn, limits the cut airflow pipe, ensuring smooth detachment and unloading from the anti-deformation rod. The operation is more labor-saving and convenient, improving work efficiency.

Technical Field

[0001] This invention relates to the technical field of airflow pipe cutting, and in particular to a cutting device for automotive airflow pipes. Background Technology

[0002] Automotive airflow ducts typically refer to two types of piping systems: air guide pipes and intake pipes, each serving different functions. Cutting devices are required during the production of automotive airflow ducts.

[0019] 2. By setting up a cutting structure and a shielding structure, the present invention can automatically move the shielding structure to the cutting position of the airflow pipe during the process of the cutting structure moving down and driving the cutter to cut the airflow pipe, thereby shielding the generated debris and greatly improving the quality of the working environment.

[0020] 3. This invention, by setting up a storage structure, a feeding structure, a top-loading structure, and a clamping structure, allows the storage structure to store the airflow pipe to be cut. The feeding structure, driven by the upper skin, moves the feeding plate to smoothly receive the airflow pipe and deliver it to the area below the first U-shaped plate. The top-loading structure automatically pushes the airflow pipe on the feeding plate upward to the cutting position, allowing the anti-deformation rod on the anti-deformation structure to be smoothly inserted into the airflow pipe for cutting and anti-deformation work. This achieves automatic feeding and further improves the cutting efficiency. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0031] Reference Figures 1-8 This invention discloses a cutting device for an automotive airflow pipe, including a workbench 1, a feeding trough 2 in the middle of the workbench 1, a discharging trough 3 on both the left and right sides of the workbench 1, a receiving structure below the discharging trough 3 inside the workbench 1, a feeding structure below the feeding trough 2 inside the workbench 1, anti-deformation structures on both the left and right edges of the workbench 1, limiting structures on both the left and right sides of the workbench 1, a first U-shaped plate 4 in the middle of the workbench 1, and a cutting structure on the first U-shaped plate 4.

[0032] The anti-deformation structure includes two sets of first mounting plates 5 connected to the left and right sides of the workbench 1. Each set of two first mounting plates 5 is rotatably connected to a screw 61. A first motor 6 is mounted on one of the first mounting plates 5 in each set. One end of the output shaft of the first motor 6 is connected to the screw 61. A movable plate 7 is sleeved on the screw 61. The movable plate 7 is attached to the workbench 1. A threaded groove is opened on the movable plate 7 for the screw 61 to pass through. An anti-deformation rod 8 is fixedly passed through the top of one side of the movable plate 7. A fixed plate 9 is fixedly sleeved in the middle of the anti-deformation rod 8.

[0033] The limiting structure includes a first transverse groove 12 opened on the workbench 1 at the front and rear sides of the unloading trough 3. A moving block 13 is slidably arranged in the first transverse groove 12. A moving frame 10 is connected to each set of two moving blocks 13. A limiting ring 11 is set in the middle of the moving frame 10. Four second transverse grooves 14 are opened on the workbench 1 at the front and rear sides of the loading trough 2. A fixed rod 17 is connected to the groove wall of each second transverse groove 14 away from the first transverse groove 12. A sleeve 15 is connected to the moving block 13. The sleeve 15 is movably sleeved on the fixed rod 17. An end sleeve 16 is fixedly sleeved on one end of the sleeve 15. A spring 18 is sleeved on the fixed rod 17. The two ends of the spring 18 are respectively connected to the end sleeve 16 and one end groove wall of the second transverse groove 14.

[0034] The material receiving structure includes two L-shaped plates 23 bolted to the rear side of the workbench 1. Each L-shaped plate 23 is positioned corresponding to the material feeding trough 3. A sleeve plate 21 is mounted on the L-shaped plate 23, and a frame 22 is movably fitted onto the sleeve plate 21. A collection frame 19 is mounted on the frame 22, and a handle 20 is provided on the front of the collection frame 19. During cutting, the first motor 6 on the first mounting plate 5 is activated, driving the screw 61 to rotate. The moving plate 7 drives the anti-deformation rod 8 to move closer to the first U-shaped plate 4, and prevents deformation. When the fixed plate 9 on the deformable rod 8 moves to the limit ring 11, as the moving plate 7 continues to move, the fixed plate 9 pushes the moving frame 10 and the moving block 13 to move together in the first transverse groove 12, thereby driving the sleeve 15 to move on the fixed rod 17. The upper end sleeve 16 of the sleeve 15 compresses the spring 18 on the fixed rod 17. When the moving block 13 slides to one end of the groove wall of the first transverse groove 12, the moving plate 7 stops moving, and the upper limit ring 11 of the moving frame 10 presses against the airflow pipe to be cut. At the end of the line, and at this time there is a cutting gap between the two anti-deformation rods 8. In this way, when cutting, the side of the anti-deformation rod 8 is close to the inner wall of the airflow pipe, so that the airflow pipe is prevented from deforming during the cutting process. After cutting, the two cut airflow pipes are respectively fitted onto the two anti-deformation rods 8. Then, the first motor 6 drives the screw 61 to rotate in the opposite direction. The moving plate 7 drives the anti-deformation rod 8 and the cut airflow pipe fitted onto the anti-deformation rod 8 to move in the opposite direction. When the anti-deformation rod 8 moves in the opposite direction, under the action of the spring 18, it pushes the moving frame 10 and the limiting ring 11 to move in the opposite direction and reset as a whole. After the moving frame 10 moves in the opposite direction and resets, the moving plate 7 continues to drive the anti-deformation rod 8 to move. Using the limiting effect of the upper limit ring 11 on the airflow pipe of the moving frame 10, the limiting ring 11 smoothly pushes the airflow pipe off the anti-deformation rod 8 during the reverse movement and reset process. After falling off, the airflow pipe falls from the discharge trough 3 into the collection frame 19 for collection.

[0035] See Figure 1 and Figure 4 The cutting structure includes a first cylinder 24 mounted on the first U-shaped plate 4, the bottom end of the output shaft of the first cylinder 24 is connected to the mounting frame 25, a second motor 26 is mounted on one side of the mounting frame 25, a cutter 27 is sleeved on the output shaft of the second motor 26, and a shielding structure is provided on the first U-shaped plate 4.

[0036] The shielding structure includes four T-shaped rods 28 that movably pass through the front and rear sides of the first U-shaped plate 4. Each set of two T-shaped rods 28 has a movably fitted drive plate 29. The drive plate 29 has a drive groove 30. Drive rods 34 are connected to both the front and rear ends of the mounting frame 25. The first U-shaped plate 4 has a through groove for the drive rods 34 to pass through. A through strip 31 that movably passes through the first U-shaped plate 4 is connected to the drive plate 29. One end of the through strip 31 is connected to a shielding cover 32. A groove 33 is cut on the shielding cover 32. After the anti-deformation rod 8 is inserted into the airflow pipe, the first cylinder 24 on the first U-shaped plate 4 is activated, causing the mounting frame 25 to move downwards. Simultaneously... The second motor 26 is started to drive the cutter 27 to rotate, and the downward-moving mounting frame 25 drives the driving rod 34 to slide downward in the driving groove 30 of the driving plate 29. The driving rod 34 squeezes the groove wall of the driving groove 30, pushing the driving plate 29 to move on the T-shaped rod 28, and through the through strip 31, it drives the two shields 32 to move and splice onto the airflow pipe. Then, as the mounting frame 25 continues to move, the rotating cutter 27 moves downward in the cutting groove 33 to cut the airflow pipe, and the debris generated during the cutting process is collected in the shields 32, which facilitates centralized treatment and improves the quality of the working environment.

[0037] See Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The feeding structure includes a feeding platform 35 set inside the workbench 1. The feeding platform 35 is perpendicular to the workbench 1. The feeding platform 35 is fixed to the workbench 1 by a connecting plate 36. Rotating rods 38 are rotatably passed through both ends of the feeding platform 35. Pulleys 39 are fixedly sleeved at both ends of each rotating rod 38. A belt 40 is tightly fitted between each group of two pulleys 39. A third motor 37 is installed at one end of one side of the feeding platform 35. The output shaft of the third motor 37 is connected to one of the rotating rods 38. Multiple connecting rods 41 are connected to each other on one side of the two belts 40. A feeding plate 42 is installed between each group of two connecting rods 41. A concave arc groove 43 is opened in the middle of one side of the feeding plate 42. A middle groove 44 is opened in the middle of the wall of the concave arc groove 43. The edges of both sides of the feeding plate 42 are inclined. A material storage structure is set at the upper rear end of the feeding platform 35. A top material structure is set at the lower middle of the feeding platform 35.

[0038] The top material structure includes a second U-shaped plate 45 fastened to the feeding table 35 by bolts. The second U-shaped plate 45 is located directly below the first U-shaped plate 4. A second cylinder 46 is installed in the middle of the lower part of the second U-shaped plate 45. The top of the output shaft of the second cylinder 46 is connected to the first lifting frame 47. A top material plate 48 is installed at the top of the first lifting frame 47. A clamping structure is provided on the top material plate 48.

[0039] The clamping structure includes a storage groove 50 on the inner walls of both sides of the top plate 48, a through groove on the lower wall of the storage groove 50, an electric telescopic rod 49 installed in the middle of the lower inner wall of the first lifting frame 47, a clamping block 51 in the storage groove 50, a push-pull plate 54 passing through the through groove connected to the lower part of the clamping block 51, a push-pull groove 55 on the push-pull plate 54, a push-pull groove 55 on the push-pull plate 54, a second lifting frame 52 connected to the top of the output shaft of the electric telescopic rod 49, a through rod 53 fixedly installed at both ends of the second lifting frame 52, and the through rod 53 movably passes through the push-pull groove 55.

[0040] The material storage structure includes second mounting plates 56 bolted to the rear ends of the left and right sides of the feeding table 35. Each of the two second mounting plates 56 is connected to a fixing plate 57. A discharge frame 58 is installed between the two fixing plates 57. A baffle 59 is installed along the upper edge of the discharge frame 58. A storage plate 60 is connected to one upper edge of the discharge frame 58. The storage plate 60 is fixedly connected to the workbench 1. Before cutting the airflow pipes, multiple airflow pipes to be cut are directly stored in the storage plate 60. The airflow pipes on the storage plate 60 roll sequentially into the discharge frame 58. The lowest airflow pipe in the discharge frame 58 is supported by the belt 40. At this time, the third motor 37 on the feeding table 35 is started, driving the rotating rod 38 and the belt 40 to rotate as a whole. When the belt 40 moves the upper plate 42 to the discharge frame 58, as the belt 40 continues to rotate, the inclined surface of the upper plate 42 squeezes the corresponding airflow pipe upwards in the discharge frame 58. When the loading plate 42 moves to the position directly below the unloading frame 58, the corresponding airflow pipe falls into the concave arc groove 43 on the loading plate 42. The rotating belt 40 then moves the loading plate 42, which supports the airflow pipe, to the position below the first U-shaped plate 4. At this point, the second cylinder 46 on the second U-shaped plate 45 is activated, which moves the top plate 48 upward. This lifts the airflow pipe at the middle groove 44 on the loading plate 42. Simultaneously, the electric telescopic rod 49 is activated, which moves the second lifting frame 52 downward. This moves the through rod 53 downward, which presses down on the wall of the push-pull groove 55 on the push-pull plate 54. This pushes the two clamping blocks 51 to clamp the airflow pipe in the top plate 48, preventing the upward-moving airflow pipe from falling off the top plate 48. When the airflow pipe moves to the cutting position and the anti-deformation rod 8 is successfully inserted into the airflow pipe, the electric telescopic rod 49 is activated to release the clamping blocks 51 on the airflow pipe. Then, the top plate 48 is moved downward to reset, allowing the airflow pipe to be cut smoothly.

[0041] The implementation principle of the cutting device for automotive airflow pipes in this embodiment of the invention is as follows: Multiple airflow pipes to be cut are directly stored in the storage plate 60. The airflow pipes on the storage plate 60 roll sequentially into the unloading frame 58. The lowest airflow pipe in the unloading frame 58 is supported by the belt 40. At this time, the third motor 37 on the feeding table 35 is started, driving the rotating rod 38 and the belt 40 to rotate as a whole. When the belt 40 moves the upper plate 42 to the unloading frame 58, as the belt 40 continues to rotate, it causes the inclined surface on the upper plate 42 to press the corresponding airflow pipe upwards in the unloading frame 58. When the upper plate 42 moves directly below the unloading frame 58, the corresponding airflow pipe falls into the concave arc groove 43 on the upper plate 42, and the lowest airflow pipe in the unloading frame 58... When the airflow pipe is supported on the belt 40, because the outer diameter of the airflow pipe is larger than the distance between the bottom surface of the unloading frame 58 and the belt 40, although the airflow pipe is supported on the belt 40, part of the airflow pipe remains in the unloading frame 58. Thus, when the belt 40 rotates, the unloading frame 58 acts as a barrier to the airflow pipe, preventing the belt 40 from moving with it. When the belt 40 moves the loading plate 42 to the airflow pipe, the rotation of the belt 40 causes the inclined surface of the loading plate 42 to press against the airflow pipe, pushing it upwards in the unloading frame 58. Furthermore, when the concave arc groove 43 on the loading plate 42 moves below the airflow pipe, the airflow pipe falls into the concave arc groove 43. Since the lowest point of the concave arc groove 43 is lower than... At the highest position of the belt 40, when the airflow pipe 40 falls into the concave arc groove 43, the airflow pipe is completely detached from the unloading frame 58, allowing the rotating belt 40 to smoothly drive the airflow pipe. When the rotating belt 40 moves the upper plate 42 supporting the airflow pipe to below the first U-shaped plate 4, the second cylinder 46 on the second U-shaped plate 45 is activated, causing the top plate 48 to move upwards. This lifts the airflow pipe at the middle groove 44 on the upper plate 42. Simultaneously, the electric telescopic rod 49 is activated, causing the second lifting frame 52 to move downwards, which in turn causes the through rod 53 to move downwards, pressing against the groove wall of the push-pull plate 54's push-pull groove 55. This pushes the two clamping blocks 51 to clamp the airflow pipe in the top plate 48, preventing the upward-moving airflow pipe from falling off the top plate 48. When the tube moves to the cutting position, the first motor 6 on the first mounting plate 5 is activated, driving the screw 61 to rotate. The moving plate 7 drives the anti-deformation rod 8 to move closer to the first U-shaped plate 4. When the fixed plate 9 on the anti-deformation rod 8 moves to the limit ring 11, as the moving plate 7 continues to move, the fixed plate 9 pushes the moving frame 10 and the moving block 13 to move together in the first transverse groove 12, thereby driving the sleeve 15 to move on the fixed rod 17. The upper end sleeve 16 of the sleeve 15 compresses the spring 18 on the fixed rod 17. When the moving block 13 slides to one end of the groove wall of the first transverse groove 12, the moving plate 7 stops moving, and the upper limit ring 11 of the moving frame 10 presses against the end of the airflow tube to be cut. Then, the first cylinder 24 on the first U-shaped plate 4 is activated, driving the mounting frame 25 to move downward.Simultaneously, the second motor 26 is activated, driving the cutter 27 to rotate. The lowering mounting frame 25 causes the driving rod 34 to slide downwards in the driving groove 30 of the driving plate 29. The pressure of the driving rod 34 against the groove wall pushes the driving plate 29 onto the T-shaped rod 28, and through the through strip 31, it moves the two shields 32 to be attached to the airflow pipe. Then, as the mounting frame 25 continues to move, the rotating cutter 27 moves downwards in the cutting groove 33 to cut the airflow pipe. The debris generated during cutting is collected in the shields 32, facilitating centralized processing and improving the working environment. Finally, the first motor 6 is activated, driving the screw... 61. Reverse rotation causes the moving plate 7 to move the anti-deformation rod 8 and the cut airflow pipe fitted on the anti-deformation rod 8 in the opposite direction. When the anti-deformation rod 8 moves in the opposite direction, the spring 18 pushes the moving frame 10 and the limiting ring 11 to move and reset as a whole in the opposite direction. After the moving frame 10 resets in the opposite direction, the moving plate 7 continues to move the anti-deformation rod 8. Using the limiting effect of the upper limit ring 11 on the airflow pipe, the limiting ring 11 smoothly pushes the airflow pipe off the anti-deformation rod 8 during the reverse reset process. The detached airflow pipe falls from the discharge trough 3 into the collection frame 19 for collection, thus achieving the cutting of the airflow pipe.

[0042] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
