Description

Technical Field

[0001] The invention relates to the technical field of metal bellows processing and forming, and in particular to a bellows processing and forming device. Background Art

[0002] In the field of metal bellows processing, forming and cutting are important production links. In the traditional bellows processing, when cutting after forming, the fixture used is often to continuously squeeze the metal bellows from both sides to fix its position. However, this fixing method has obvious disadvantages.

[0003] On the one hand, due to the material characteristics of the metal bellows itself, some areas are prone to deformation when subjected to continuous lateral extrusion. This will not only affect the appearance of the bellows, but may also damage its internal structure, thereby affecting the performance and quality of the bellows. For example, in some application scenarios that require high dimensional accuracy and shape of bellows, such as automotive exhaust systems, aerospace pipeline connections, etc., slight deformation may cause the entire system's sealing, stability and other performance to deteriorate, and even cause safety hazards.

[0004] On the other hand, the traditional fixture fixing method also has limitations in operation. It is difficult to flexibly adjust according to the different specifications and shapes of the corrugated pipe, and its adaptability is poor, which to a certain extent limits the improvement of production efficiency and the consistency of product quality. Moreover, during the cutting process, due to the uneven squeezing of the corrugated pipe by the fixture, it may also cause the cutting surface to be uneven, further affecting the subsequent assembly and use.

[0025] Reference Figure 1 to Figure 7, which is the first embodiment of the present invention, proposes a bellows processing forming device for processing a metal bellows 1, comprising a device body 2; an annular mounting frame 3 is arranged at the unloading end of the device body 2, the annular mounting frame 3 has an annular guide rail 301, the annular guide rail 301 coincides with the axis of the metal bellows 1; a plurality of clamps 4, and the plurality of clamps 4 are circumferentially spaced and slidably arranged on the annular guide rail 301; a plurality of first rollers 5, the first rollers 5 are rotatably arranged at one end of the clamps 4, and are used for rolling abutment with the metal bellows 1.

[0026] In this embodiment, in order to solve the problem in the related art that when the metal bellows is cut after forming, the fixture continues to squeeze the metal bellows from both sides, and some areas of the metal bellows are easily squeezed and deformed, a bellows processing forming device is designed. The device body 2 is a corrugated forming device for a metal bellows. The annular mounting frame 3 is fixed to the unloading end of the device body 2 by welding or bolting, and a precise annular guide rail 301 is processed on the annular mounting frame 3. The guide rail perfectly coincides with the axis of the metal bellows 1 to ensure the accuracy of subsequent operations. The clamp 4 adopts a special metal clamping claw structure, the number of which is 2 (adjustable according to actual needs), evenly distributed at circumferential intervals, and the clamp 4 slides smoothly on the annular guide rail 301. The first roller 5 is installed at the other end of the clamp 4 through a bearing. Its diameter and shape are selected according to the size and process requirements of the metal bellows 1, and it can roll and abut against the surface of the metal bellows 1 well, and play a supporting and guiding role during the movement of the metal bellows 1.

[0027] The advantage is that, by providing an annular mounting frame 3 and a clamp 4 that can slide on the annular guide rail 301, and a first roller 5 that rolls against the metal bellows 1, the metal bellows 1 can be supported from all directions, thereby solving the problem that when the metal bellows 1 is cut after being formed, the clamp 4 continues to squeeze the metal bellows 1 from both sides, and some areas of the metal bellows 1 are easily squeezed and deformed. This ensures the stability and accuracy of the metal bellows 1 during the processing and improves the processing quality and production efficiency of the metal bellows 1.

[0028] Furthermore, the annular guide rail 301 has a slide groove 302 and also includes an arc-shaped slider 6, which is slidably set in the slide groove 302. Several clamps 4 are connected to the arc-shaped slider 6 to drive several clamps 4 to slide synchronously; the first driving member 7 is set on any clamp 4 to drive any clamp 4 to slide on the annular guide rail 301.

[0029] In this embodiment, a slide groove 302 is processed on the annular guide rail 301, and the arc-shaped slider 6 is a metal rod with certain strength and toughness, whose shape matches the curvature of the annular guide rail 301 and fits closely with the slide groove 302, so that the arc-shaped slider 6 can slide stably in the slide groove 302. The clamp 4 is connected to the arc-shaped slider 6, and when the arc-shaped slider 6 slides, it can drive all the clamps 4 to slide synchronously. The first driving member 7 uses a motor. After the motor is started, the clamp 4 is driven to slide on the annular guide rail 301 through the transmission structure on the clamp 4 to adjust the position of the clamp 4.

[0030] The advantage is that the arrangement of the arc-shaped slider 6 and the first driving member 7 enables the clamps 4 to slide synchronously, while ensuring the consistency of the movements of multiple clamps 4, further enhancing the supporting and fixing effect of the metal bellows 1.

[0031] Furthermore, the outer side of the annular guide rail 301 away from the device body 2 has a first tooth 3011, and the clamp 4 includes a sliding mounting frame 401, which is slidably set on the annular guide rail 301; the first gear 402 is rotatably set at one end of the sliding mounting frame 401 close to the first tooth 3011 and meshes with the first tooth 3011. After the first gear 402 rotates, it drives the sliding mounting frame 401 to slide, and the first driving member 7 is used to drive the first gear 402 to rotate.

[0032] In this embodiment, the outer side of the annular guide rail 301 away from the device body 2 is processed with uniformly distributed first teeth 3011. The sliding mounting frame 401 is a metal mounting plate, the shape of which matches the annular guide rail 301, so as to realize the sliding of the sliding mounting frame 401 on the annular guide rail 301. The first gear 402 is installed on the end of the sliding mounting frame 401 close to the first teeth 3011 through a shaft and a bearing, and the first gear 402 is tightly meshed with the first teeth 3011. The first driving member 7 is a servo motor, and the output shaft of the motor is connected to the shaft of the first gear 402 through a coupling. When the motor drives the first gear 402 to rotate, due to the meshing action of the gear and the first teeth 3011, the sliding mounting frame 401 is driven to slide on the annular guide rail 301, so as to realize the sliding of the fixture.

[0033] The advantage is that by utilizing the meshing transmission of the first gear 402 and the first tooth 3011 on the outer side of the annular guide rail 301, precise sliding of the sliding mounting frame 401 can be achieved, the accuracy and stability of the position adjustment of the clamp 4 are improved, and good coordination between the metal bellows 1 and the clamp 4 during processing is ensured, thereby improving processing quality and efficiency.

[0034] Furthermore, the inner side of the end of the annular guide rail 301 away from the device body 2 has a second tooth 3012, and the clamp 4 also includes a rotating shaft 403, which is rotatably set on the end of the sliding mounting frame 401 close to the second tooth 3012; the second gear 404 is set on the end of the rotating shaft 403 close to the annular guide rail 301, meshing with the second tooth 3012, and after the sliding mounting frame 401 slides, the second gear 404 rotates; the third gear 405 is set at the other end of the rotating shaft 403, and rotates synchronously with the second gear 404; the rack 406 is slidably set on the sliding mounting frame 401, meshing with the third gear 405, and the first roller 5 is rotatably set on the end of the rack 406 close to the metal bellows 1, and after the rack 406 slides, the first roller 5 abuts or releases the abutment with the metal bellows 1.

[0035] In this embodiment, the inner side of the end of the annular guide rail 301 away from the device body 2 is processed with a second tooth 3012. The rotating shaft 403 is installed on the end of the sliding mounting frame 401 close to the second tooth 3012 through a bearing seat and can rotate freely. The second gear 404 is installed on the end of the rotating shaft 403 close to the annular guide rail 301 and meshes with the second tooth 3012. When the sliding mounting frame 401 slides, the second gear 404 will rotate accordingly due to the action of the second tooth 3012. The third gear 405 is installed on the other end of the rotating shaft 403 and is connected with the second gear 404 through a key to achieve synchronous rotation. The rack 406 is installed on the sliding mounting frame 401 through a guide rail slider structure and meshes with the third gear 405. The first roller 5 is installed on the mounting seat of the rack 406 close to the metal bellows 1 through a shaft and a bearing. When the rack 406 slides, the first roller 5 can abut or release the abutment with the metal bellows 1 to achieve the clamping and loosening operation of the metal bellows 1.

[0036] The advantage is that, through the cooperation of the second tooth 3012, the second gear 404, the third gear 405 and the rack 406, the abutment and release of the first roller 5 and the metal bellows 1 can be automatically controlled while the sliding mounting frame 401 slides, which not only improves the degree of automation of the operation, but also can timely and accurately adjust the clamping force and position of the first roller 5 on the metal bellows 1 according to the processing requirements of the metal bellows 1, thereby ensuring the stability and precision of the metal bellows 1 during the processing, and effectively improving the processing quality and production efficiency.

[0037] Furthermore, the third gear 405 has a plug-in slot 4051 on the inner side, and the third gear 405 is relatively rotatably arranged at the end of the rotating shaft 403 away from the second gear 404, and also includes a pin shaft 8, which is slidably arranged at the end of the rotating shaft 403 close to the third gear 405. After the pin shaft 8 slides out, one end extends into the plug-in slot 4051, so that the third gear 405 rotates synchronously with the rotating shaft 403; the two ends of the first elastic member 9 are respectively connected to the pin shaft 8 and the rotating shaft 403, so as to provide a force for resetting the pin shaft 8; the pin 18 is slidably arranged on the sliding mounting frame 401, and after the third gear 405 does not rotate synchronously with the rotating shaft 403, the pin 18 passes through the third gear 405 to limit the rotation position of the third gear 405.

[0038] In this embodiment, a plug-in slot 4051 is processed on the inner side of the third gear 405, and the third gear 405 is relatively rotatably arranged at the end of the rotating shaft 403 away from the second gear 404. The pin 8 is a cylindrical metal rod, which is installed on the end of the rotating shaft 403 close to the third gear 405 through a guide rail and a first elastic member 9. One end of the first elastic member 9 is connected to the rotating shaft 403, and the other end is connected to the pin 8 to provide a reset force for the pin 8. The rotating shaft 403 has an electromagnetic function. When the third gear 405 and the rotating shaft 403 need to rotate synchronously, the rotating shaft 403 is energized, and the pin 8 is pushed out under the action of the electromagnetic force, so that one end of the pin extends into the plug-in slot 4051, so that the synchronous rotation of the two is achieved. The latch 18 is also a cylindrical metal rod, which is installed on the sliding mounting frame 401 through a sliding hole. An electromagnetic device is set on the other side of the sliding mounting frame 401 to control the sliding extension of the latch 18. When the third gear 405 does not need to rotate synchronously with the rotating shaft 403, the latch 18 is slidably inserted into the socket of the third gear 405 to limit the rotation position of the third gear 405 so that it can continuously clamp the metal bellows 1.

[0039] The advantage is that the arrangement of the pin 8 and the latch 18 allows the connection and separation between the third gear 405 and the rotating shaft 403 to be flexibly controlled, thereby realizing accurate control of the position and movement of the first roller 5. When the metal bellows 1 needs to be clamped or adjusted, it can ensure that the third gear 405 rotates synchronously with the rotating shaft 403 to achieve accurate operation; after the clamping and loosening operations are completed, the rotation of the third gear 405 is limited by the latch 18, thereby improving the safety and stability of the device, avoiding abnormal changes in the clamping state of the first roller 5 on the metal bellows 1 due to misoperation or other factors, and ensuring the processing quality of the metal bellows 1 and the smooth progress of the production process.

[0040] Furthermore, the clamp 4 also includes a roller mounting frame 407, one end of the roller mounting frame 407 has two mounting portions 4071, and the other end of the roller mounting frame 407 is arranged on the end of the rack 406 close to the metal bellows 1, and the first roller 5 is rotatably arranged on one end of the rack 406 through the mounting portion 4071.

[0041] In this embodiment, the roller mounting frame 407 is made of metal plate, and has two symmetrical mounting parts 4071 at one end, and bearing holes are processed on the mounting parts 4071. The other end of the roller mounting frame 407 is fixed to the end of the rack 406 close to the metal bellows 1 by welding or bolt connection. The first roller 5 is mounted on the mounting part 4071 of the roller mounting frame 407 through a shaft and a bearing, and can rotate freely, ensuring smooth rolling contact with the metal bellows 1, reducing friction, and improving the support and guiding effect of the metal bellows 1.

[0042] The advantage is that the design of the roller mounting frame 407 provides a stable mounting position for the first roller 5, so that it can accurately contact and function with the metal bellows 1. Through reasonable structural design, the rotation flexibility and reliability of the first roller 5 are guaranteed, the wear and energy loss of the metal bellows 1 during the processing are effectively reduced, the processing accuracy and surface quality of the metal bellows 1 are improved, and the service life of the first roller 5 is extended.

[0043] Furthermore, it also includes a swing mounting frame 10, which has two swing mounting frames 10, one end of which is swingably set on both sides of the roller mounting frame 407; the second roller 11 is rotatably set at the other end of the swing mounting frame 10; the two ends of the second elastic member 12 are respectively connected to the roller mounting frame 407 and the swing mounting frame 10, for providing force for the swing mounting frame 10 to approach the roller mounting frame 407.

[0044] In this embodiment, the swing mounting frame 10 is a two metal rod-shaped structure, one end of which is swingably mounted on both sides of the roller mounting frame 407 through a hinge or a pin 8. The second roller 11 is a small rubber roller, which is mounted on the other end of the swing mounting frame 10 through a shaft and a bearing. The second elastic member 12 is a spring, and the two ends of the spring are respectively connected to the roller mounting frame 407 and the swing mounting frame 10, providing a force for the swing mounting frame 10 to approach the roller mounting frame 407, so that the second roller 11 can be closely attached to the surface of the metal bellows 1, playing a role of auxiliary support and guidance.

[0045] The advantage is that the arrangement of the swing mounting frame 10 and the second roller 11 increases the support points and contact area of ​​the metal bellows 1, and improves the stability of the metal bellows 1 during processing. The second elastic member 12 enables the second roller 11 to adapt to the surface shape and size changes of the metal bellows 1, and always maintain good contact with the metal bellows 1, further enhancing the support and guiding effect of the metal bellows 1, reducing the vibration and deformation of the metal bellows 1 during processing, and improving the processing quality and precision.

[0046] Furthermore, the second rollers 11 are used in groups and have two groups, each group has a certain number of rollers. The second rollers 11 used in groups are all rotatably set on the end of the swing mounting frame 10 away from the roller mounting frame 407, and also include a third elastic member 13. The third elastic member 13 has a certain number of third elastic members 13. Both ends of the third elastic member 13 are respectively abutted against two adjacent second rollers 11 for adjusting the spacing between adjacent second rollers 11.

[0047] In this embodiment, the second rollers 11 are used in groups, each group has 4 (the number can be adjusted according to actual needs), and the two groups are respectively installed on two swing mounting frames 10. The third elastic member 13 is a small rubber pad or spring sheet, and the number is the same as the number of adjacent groups of second rollers 11. The two ends of the third elastic member 13 are respectively in contact with the shafts or mounting seats of the two adjacent second rollers 11, and the spacing between the adjacent second rollers 11 is adjusted through its elastic deformation, so that the second rollers 11 can better adapt to the metal bellows 1 of different diameters and shapes, and improve the adaptability and support effect of the metal bellows 1.

[0048] The advantage is that the arrangement of the second rollers 11 and the third elastic member 13 used in groups further enhances the support and adaptability of the metal bellows 1. The spacing between the second rollers 11 can be automatically adjusted according to the actual size and shape of the metal bellows 1, so that the second rollers 11 can smoothly enter the wave bottom of the metal bellows 1, and at the same time, the first roller 5 abuts against the wave crest of the metal bellows 1, ensuring uniform support and close fit of the metal bellows 1, reducing local stress concentration of the metal bellows 1 during processing, improving the overall quality and processing accuracy of the metal bellows 1, and at the same time reducing the influence of the size difference of the metal bellows 1 on the processing process, and improving the versatility of the device.

[0049] Furthermore, it also includes a rotating plate 14, which is rotatably set on one end of the annular guide rail 301 close to the device body 2 and coincides with the axis of the annular guide rail 301; the saw blade 15 is relatively rotatable and slidably set on the side of the rotating plate 14 close to the device body 2, and the saw blade 15 slides close to or away from the metal bellows 1. After the rotating plate 14 rotates, the saw blade 15 moves in a circle around the axis of the metal bellows 1.

[0050] In this embodiment, the rotating plate 14 is a circular metal plate, which is rotatably arranged on the end of the annular guide rail 301 close to the device body 2 and coincides with the axis of the annular guide rail 301. The saw blade 15 is relatively rotatably and slidably arranged on the side of the rotating plate 14 close to the device body 2 through an adjustable mounting frame, and the mounting frame is provided with a guide rail and a slider to make the saw blade 15 approach or move away from the metal bellows 1. When the rotating plate 14 rotates, the saw blade 15 can move circumferentially around the axis of the metal bellows 1 to achieve the cutting operation of the metal bellows 1.

[0051] Furthermore, it also includes a connecting rod 16, both ends of which are respectively connected to one side of the rotating plate 14 and the sliding mounting frame 401. After the sliding mounting frame 401 slides, it drives the rotating plate 14 to rotate synchronously; one end of the second driving member 17 is set on the roller mounting frame 407, and the other end drives the saw blade 15 to rotate. After the roller mounting frame 407 slides, it drives the first roller 5 to abut against the metal bellows 1, so that the saw blade 15 abuts against the metal bellows 1.

[0052] In this embodiment, the connecting rod 16 is a metal rod, and its two ends are respectively connected to one side of the rotating plate 14 and the sliding mounting frame 401. When the sliding mounting frame 401 slides on the annular guide rail 301, the rotating plate 14 is driven to rotate synchronously through the connecting rod 16. The second driving member 17 uses an electric motor, which is fixed to the roller mounting frame 407 through a mounting seat. The output shaft of the motor is connected to the shaft of the saw blade 15. When the roller mounting frame 407 slides, it drives the first roller 5 to abut against the metal bellows 1, and drives the second driving member 17 to move in a direction close to the metal bellows 1, so that the saw blade 15 contacts the metal bellows 1, and the metal bellows 1 is cut under the rotation of the rotating plate 14.

[0053] The advantage is that the connection of the connecting rod 16 enables the sliding of the sliding mounting frame 401 and the rotation of the rotating plate 14 to be linked, ensuring that the saw blade 15 can accurately reach the processing position and start to rotate while the first roller 5 clamps and positions the metal bellows 1, thereby realizing the automation and coordination of the processing process. The processing efficiency is improved, the error and time cost of manual operation are reduced, and the overall stability and reliability of the device are enhanced, ensuring the quality and accuracy of the processing of the metal bellows 1.
