Description

Technical Field

[0001] This invention relates to the field of aluminum profile shaping technology, and more specifically, to an online aluminum profile shaping device and shaping method. Background Technology

[0002] Aluminum profiles are profiles with various cross-sections made from aluminum alloy through processes such as extrusion and aging. They are widely used in construction and other fields. For example, aluminum profile ladders are lightweight and easy to move by hand, and their high-strength structure can meet the load-bearing requirements of household or engineering projects. Their corrosion resistance makes them suitable for outdoor and humid environments. During production and transportation, the profiles are prone to deformation due to stress release and external impact. When making ladders from aluminum profiles, it is necessary to shape them to ensure the straightness of the ladder frame and the flatness of the joints. Therefore, it is necessary to use shaping processes such as roll forming to ensure the shape of the aluminum profiles.

[0003] Currently, existing aluminum profile forming devices utilize roller pressing for forming. The roller surface is designed according to the conventional U-shaped aluminum profile cross-section. The roller structure used for forming is only suitable for conventional U-shaped aluminum profiles with vertical sides, and is not suitable for U-shaped aluminum profiles with beveled sides, which can easily cause secondary damage. Specifically, the roller is set according to the vertical side of the conventional U-shaped aluminum profile. When the U-shaped aluminum profile with beveled sides enters, the vertical sidewall of the roller can only contact the beveled edge of the U-shaped aluminum profile. The extrusion pressure is concentrated at the edge and not in the forming area of ​​the entire surface. This method results in the inability to correct the deviation of the beveled side and the problem of excessive deformation of the beveled side.

[0004] The staff made improvements to address the existing shortcomings. One of the improvements was the use of a contour roller design. A chamfer was created on the outer wall of the roller, and this chamfer was designed to fit the angle of the U-shaped aluminum profile. When the aluminum profile passes through the roller, the bevel is shaped.

[0005] However, for aluminum profiles with small bevel angles and wide bevels, the bevel area of ​​the workpiece is large, so the chamfer on the roller needs to cover a larger area. If the roller is too thin, it cannot meet the chamfering requirements. Therefore, the roller is axially thickened to meet the chamfering requirements. However, axial thickening of the roller directly increases the axial volume of the roller, leading to an increase in raw material costs. At the same time, the axial weight increases, increasing the axial load on the drive. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an online aluminum profile shaping device and shaping method.

[0012] The present invention is further configured such that: each of the two sets of shaping components includes a first shaping mechanism, a second shaping mechanism, and two sets of positioning mechanisms; the two sets of positioning mechanisms are sleeved on the outer side wall of the corresponding drive rod; the first shaping mechanism and the second shaping mechanism are correspondingly arranged with the two sets of positioning mechanisms; the first shaping mechanism and the second shaping mechanism are respectively sleeved on the outer side wall of the corresponding positioning mechanism; and the side walls of the first shaping mechanism and the second shaping mechanism are respectively provided with two sets of connecting mechanisms.

[0013] The present invention is further configured such that: the positioning mechanism includes a collar sleeved on the outer wall of the corresponding drive rod, one end of the outer wall of the collar is connected to a retaining ring, and the outer wall of the collar is threadedly connected to a second locking bolt, one end of the second locking bolt extending into the interior of the collar.

[0014] The present invention is further configured such that: the first shaping mechanism includes two first arc-shaped plates, the inner rings of the two first arc-shaped plates are provided with first arc-shaped grooves with the same outer diameter as the corresponding collar, the two first arc-shaped plates are sleeved on the outer side wall of the corresponding collar using the first arc-shaped grooves, the two first arc-shaped plates cooperate to form a ring structure, and two sets of connecting mechanisms corresponding to the first shaping mechanism are respectively inserted into the two first arc-shaped plates.

[0015] The present invention is further configured such that: the second shaping mechanism includes two second arc-shaped plates, the inner rings of the two second arc-shaped plates are provided with second arc-shaped grooves, the two second arc-shaped plates are sleeved on the outer side wall of the corresponding collar through the second arc-shaped grooves, the two second arc-shaped plates cooperate to form a ring structure, two sets of connecting mechanisms corresponding to the second shaping mechanism are respectively inserted into the two second arc-shaped plates, and one end of each of the two second arc-shaped plates is provided with a guide surface.

[0016] The present invention is further configured such that: the connecting mechanism includes a frame, and a rotating column is provided at both ends of the frame, one of the rotating columns is rotatably connected to the frame, and an adjusting screw is connected to the end of the other rotating column.

[0018] The online shaping method for aluminum profiles, using the online shaping device for aluminum profiles as described above, includes the following steps:

[0019] S1. Assemble the shaping components according to the workpiece and install them on the swing mechanism. Then, adjust the height of the ball joint mechanism by rotating the handle and the lifting screw. After that, adjust the position of the two sets of auxiliary components so that the shaping components and auxiliary components work together to form a shaping path that is compatible with the workpiece.

[0020] S2. Then place the workpiece on top of the roller conveyor mechanism, which drives the workpiece forward toward the shaping assembly to prepare for the shaping operation.

[0021] S3. When the workpiece approaches the position of the shaping component, the swing mechanism drives the shaping component to rotate as a whole. When the workpiece reaches the position of the shaping component, the rotating shaping component squeezes and shapes the inclined edge of the workpiece, causing the inclined edge of the workpiece to be shaped. When the workpiece reaches the position of the auxiliary component, the auxiliary component further shapes the inner side of the inclined edge. After the workpiece passes through the auxiliary component, the overall shaping operation is completed.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] (1) By rotating the extrusion screw to adjust the angle between the L-shaped plate and the drive rod, the angle of the outer guide surface of the first and second forming mechanisms can be changed. This can adapt to U-shaped workpieces with beveled edges, without the need to use axially thickened rollers to meet the forming requirements of workpieces with different beveled edges, thus improving the versatility and practicality of the forming components.

[0024] (2) By setting up a first shaping mechanism and a second shaping mechanism, the first shaping mechanism is composed of two first arc plates, the second shaping mechanism is composed of two second arc plates, and a matching connecting mechanism, the target shaping mechanism can be disassembled and installed independently without disassembling other shaping mechanisms, reducing the difficulty and complexity of operation, and avoiding the need to readjust the position of the shaping mechanism after reinstallation.

[0025] (3) Insert the two rods on the connecting mechanism into the corresponding positioning holes on the side walls of the two first arc plates respectively. Then rotate the frame so that the frame and the adjusting screw rotate relative to each other. The adjusting screw is screwed into the frame. At this time, the two rotating columns will be pulled closer to each other. At this time, the two arc plates can be spliced ​​and positioned by mutual compression. Conversely, by rotating the frame in the opposite direction, the two rotating columns can be separated, and the connecting mechanism can be quickly disassembled, thereby achieving the stability of the arc plate splicing and the convenience of disassembly and assembly.

[0026] (4) By setting the first arc plate, the second arc plate with the guide surface and the tapered tube of the auxiliary component, the three work together to form a complete shaping path, which respectively adapts to the workpiece’s outward expansion and inward contraction of the inclined edge shaping requirements, and at the same time achieves the effect of secondary shaping of the inner side of the workpiece’s inclined edge.

[0048] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0050] Please see Figures 1-12 The present invention provides the following technical solutions:

[0051] Example 1, see Figure 1 The online forming device for aluminum profiles includes a roller conveyor mechanism 1 and a drive assembly 2 located above the roller conveyor mechanism 1. The top of the roller conveyor mechanism 1 conveys a workpiece 5. The roller conveyor mechanism 1 is used to drive the workpiece 5 to move, so that the workpiece 5 can move towards the forming station, which facilitates subsequent forming operations.

[0052] See Figure 1 Two sets of shaping components 3 are installed on the drive component 2. The drive component 2 is used to drive the shaping components 3 to rotate, thereby enabling the workpiece 5 to be shaped.

[0053] See Figure 1 and Figure 2 The specific structure of driver component 2 is as follows:

[0054] The drive assembly 2 includes two legs 21, a gantry 22 is mounted on the top of the two legs 21, an adjustment mechanism 23 is slidably connected inside the two gantry 22, and a top plate is connected to the top of the two gantry 22. The gantry 22, the legs 21 and the top plate cooperate to form a support frame, and two sets of adjustment mechanisms 23 are installed on this support frame.

[0055] See Figures 3-5Both sets of adjustment mechanisms 23 include a ball joint hinge mechanism 233 slidably connected inside the corresponding gantry frame 22. The top of the ball joint hinge mechanism 233 is rotatably connected to a lifting screw 232 via a bearing. The top of the lifting screw 232 passes through the top plate and is threadedly connected to the top plate. A handle 231 is connected to the top of the lifting screw 232. The operator rotates the handle 231 by hand, thereby driving the lifting screw 232 to extend and retract on the gantry frame 22, thereby adjusting the height of the ball joint hinge mechanism 233. A swing mechanism 234 is installed inside the ball joint hinge mechanism 233. Two sets of shaping components 3 are respectively installed on the two swing mechanisms 234. When the ball joint hinge mechanism 233 is raised and lowered, it drives the swing mechanism 234 and the corresponding shaping component 3 to rise and fall, so that the shaping component 3 can be adapted to the height of the workpiece 5.

[0056] See Figures 3-5 A support plate is provided on one side of the ball joint mechanism 233. The swing mechanism 234 includes an L-shaped plate 2341 located below the support plate. A drive motor 2342 is installed on the side of the L-shaped plate 2341 away from the ball joint mechanism 233. The output end of the drive motor 2342 is connected to a drive rod 2343. The drive rod 2343 passes through the middle of the inner ring of the ball joint mechanism 233 and is connected to the middle of the inner ring of the ball joint mechanism 233. Two sets of shaping components 3 are respectively installed on the outer walls of the two drive rods 2343.

[0057] The drive motor 2342 is used to drive the drive rod 2343 to rotate, thereby driving the corresponding shaping component 3 to rotate. When the roller conveyor 1 moves the workpiece 5 toward the shaping component 3, the shaping component 3 rotates accordingly. When the workpiece 5 is conveyed to the position of the shaping component 3, the shaping component 3 squeezes and shapes the moving workpiece 5.

[0058] See Figure 6Both shaping components 3 include a first shaping mechanism 31, a second shaping mechanism 32, and two sets of positioning mechanisms 33. The two sets of positioning mechanisms 33 are sleeved on the outer walls of the corresponding drive rods 2343. The first shaping mechanism 31 and the second shaping mechanism 32 are correspondingly arranged with the two sets of positioning mechanisms 33. The first shaping mechanism 31 and the second shaping mechanism 32 are respectively sleeved on the outer walls of the corresponding positioning mechanisms 33. The first shaping mechanism 31 and the second shaping mechanism 32 can be extrusion wheels. The first shaping mechanism 31 and the second shaping mechanism 32 are fixed on the corresponding positioning mechanisms 33 for positioning. The two positioning mechanisms 33 can be positioned on the drive rods 2343. The first shaping mechanism 31 and the second shaping mechanism 32 slide on the outer wall of the 43, thereby adjusting their positions. This allows the positions of the first shaping mechanism 31 and the second shaping mechanism 32 to be adjusted according to the side of the workpiece 5. Furthermore, by adjusting one of the positioning mechanisms 33 individually, the distance between the first shaping mechanism 31 and the second shaping mechanism 32 can be changed, allowing the side of the workpiece 5 to move between the first shaping mechanism 31 and the second shaping mechanism 32. During the movement of the workpiece 5, the side of the workpiece 5 can be shaped by the limiting effect of the first shaping mechanism 31 and the second shaping mechanism 32.

[0059] See Figure 7 The positioning mechanism 33 includes a collar 331 sleeved on the outer wall of the corresponding drive rod 2343. A retaining ring 332 is connected to one end of the outer wall of the collar 331. A second locking bolt 333 is threaded onto the outer wall of the collar 331, with one end of the second locking bolt 333 extending into the interior of the collar 331. The collar 331 serves as a support for the first shaping mechanism 31 and the second shaping mechanism 32. The first shaping mechanism 31 and the second shaping mechanism 32 are sleeved onto the outer wall of the corresponding collar 331. The collar 331 is sleeved onto the outer wall of the drive rod 2343, and the retaining ring 332 can... The positions of the first shaping mechanism 31 and the second shaping mechanism 32 are defined by the movement of the collar 331, thereby adjusting the positions of the first shaping mechanism 31 and the second shaping mechanism 32. After the adjustment is completed, the collar 331 is positioned on the outer wall of the drive rod 2343 by rotating the second locking bolt 333. Then, the side of the workpiece 5 moves between the first shaping mechanism 31 and the second shaping mechanism 32. During the movement of the workpiece 5, the side of the workpiece 5 can be shaped by the limiting effect of the first shaping mechanism 31 and the second shaping mechanism 32.

[0060] In the second embodiment, the roller structure for shaping (i.e., the first shaping mechanism 31 and the second shaping mechanism 32) is only suitable for workpieces 5 with a conventional U-shaped vertical side. It is not suitable for workpieces 5 with a U-shaped oblique side, which can easily cause secondary damage. Specifically, the roller is set according to the vertical side of the conventional U-shaped workpiece 5. When the workpiece 5 with an oblique U-shaped side enters, the vertical sidewall of the roller can only contact the oblique edge of the workpiece 5 with an oblique side. The pressing force is concentrated at the edge and not in the shaping area of ​​the whole surface. This method leads to the inability to correct the deviation of the oblique side and the problem of excessive deformation of the oblique side.

[0061] In the conventional method, a contour roller design is used, with a chamfer on the outer wall of the roller. This chamfer is designed to fit the angle of the workpiece 5, which is U-shaped with an inclined side. When the workpiece 5 passes through the roller, the inclined side can be shaped.

[0062] However, for workpiece 5 with a small included angle on the hypotenuse and a wide hypotenuse, the area of ​​the hypotenuse of workpiece 5 is large. Therefore, the chamfer on the roller needs to cover a larger area. If the roller is too thin, it cannot meet the chamfering requirements. Therefore, the roller is axially thickened to meet the chamfering requirements. However, axially thickening the roller directly increases the axial volume of the roller, which leads to an increase in raw material costs. At the same time, the axial weight increases, which increases the axial load on the drive rod 2343.

[0063] For this purpose, please refer to Figures 3-5 A hinge seat 2345 is installed on the top of the L-shaped plate 2341. A hinge plate 2347 is hinged to the top of the hinge seat 2345. A through groove is opened on the top of the bearing plate. The top of the hinge plate 2347 passes through the inside of the through groove. A pressing screw 2344 is threaded to the top of the bearing plate. The bottom end of the pressing screw 2344 is hinged to the top of the L-shaped plate 2341. A first locking bolt 2346 is threaded to one side of the bearing plate. One end of the first locking bolt 2346 extends into the inside of the through groove. The ball joint mechanism 233 includes a frame and a ball. Openings are provided on both sides of the frame. The ball rotates inside the frame. A through hole is opened inside the ball. The drive rod 2343 passes through the through hole and is connected to the ball. When the drive rod 2343 swings, the drive rod 234... The 3rd mechanism causes the ball to swing inside the frame. At the same time, when the drive rod 2343 rotates, it can also cause the ball to rotate inside the frame. The swing and rotation of the drive rod 2343 will not interfere with each other. By rotating the extrusion screw 2344, the L-shaped plate 2341 is extruded, causing the L-shaped plate 2341 and the drive rod 2343 to change angles, thereby adjusting the angles of the first shaping mechanism 31 and the second shaping mechanism 32. The first shaping mechanism 31 and the second shaping mechanism 32 adjust the angle of their outer wall chamfers without increasing the thickness. After the adjustment is completed, the hinge plate 2347 is locked by the first locking bolt 2346. This adjustment method further enables the shaping component 3 to adapt to the shaping of other shaped profiles, so that the chamfer can adapt to the angles of different bevels.

[0064] In Example 3, since the first shaping mechanism 31 and the second shaping mechanism 32 are installed on the same drive rod 2343, and one end of the drive rod 2343 needs to be connected to the drive, the first shaping mechanism 31 and the second shaping mechanism 32 need to be installed from the end of the drive rod 2343 that is not connected to the drive. When the first shaping mechanism 31 needs to be disassembled, if the first shaping mechanism 31 is close to the installation end of the drive rod 2343, it can be directly removed from the corresponding positioning mechanism 33. However, if the first shaping mechanism 31 is far from the installation end of the drive rod 2343 and is blocked by the second shaping mechanism 32, the second shaping mechanism 32 needs to be disassembled first, and the positioning mechanism 33 corresponding to the second shaping mechanism 32 needs to be disassembled at the same time before the first shaping mechanism 31 can be disassembled and removed. The operation is cumbersome, and after reinstallation, the positions of the first shaping mechanism 31 and the second shaping mechanism 32 need to be readjusted.

[0065] Therefore, improvements were made to the first shaping mechanism 31 and the second shaping mechanism 32.

[0066] See Figures 8-12 The first shaping mechanism 31 includes two first arc-shaped plates 311. The inner ring of the two first arc-shaped plates 311 is provided with a first arc-shaped groove 312 with the same outer diameter as the corresponding collar 331. The two first arc-shaped plates 311 are fitted onto the outer wall of the corresponding collar 331 using the first arc-shaped groove 312. The two first arc-shaped plates 311 cooperate to form a ring structure. That is, when the first shaping mechanism 31 is installed on the corresponding positioning mechanism 33, the two first arc-shaped plates 311 are locked onto the outer wall of the corresponding collar 331. When removing them, it is only necessary to separate the two first arc-shaped plates 311.

[0067] See Figure 10 The second shaping mechanism 32 includes two second arc-shaped plates 321. The inner ring of the two second arc-shaped plates 321 is provided with a second arc-shaped groove 322. The two second arc-shaped plates 321 are fitted onto the outer wall of the corresponding collar 331 through the second arc-shaped groove 322. The two second arc-shaped plates 321 cooperate to form a ring structure. The two second arc-shaped plates 321 are used in the same way as the first arc-shaped plate 311. They are assembled by splicing and can be removed by separating them during disassembly.

[0068] The side walls of the first shaping mechanism 31 and the second shaping mechanism 32 are respectively provided with two sets of connecting mechanisms 34. When the two first arc-shaped plates 311 are locked on the outer wall of the corresponding collar 331, the retaining ring 332 on the outer wall of the corresponding collar 331 provides auxiliary limiting. After the locking is completed, the corresponding two sets of connecting mechanisms 34 provide auxiliary connection and positioning. The installation method of the two second arc-shaped plates 321 is the same as that of the two first arc-shaped plates 311.

[0069] See Figure 11The connecting mechanism 34 includes a frame 341, with rotating columns 342 at both ends of the frame 341. One rotating column 342 is rotatably connected to the frame 341, and the end of the other rotating column 342 is connected to an adjusting screw 344, which is threadedly connected to the frame 341. Insert rods 343 are connected to the side walls of both rotating columns 342. Positioning holes corresponding to the insert rods 343 are opened on the side walls of the first arc plate 311 and the second arc plate 321, and the insert rods 343 are inserted into the corresponding positioning holes.

[0070] After the two first arc-shaped plates 311 are spliced ​​together, the two insert rods 343 on the connecting mechanism 34 are respectively inserted into the corresponding positioning holes on the side walls of the two first arc-shaped plates 311. At this time, the two connecting mechanisms 34 can connect the two first arc-shaped plates 311. Furthermore, since the insert rods 343 have been inserted into the corresponding positioning holes, the two rotating columns 342 remain stationary. At this time, the operator rotates the frame 341, causing the frame 341 and the adjusting screw 344 to rotate relative to each other. The adjusting screw 344 is screwed into the frame 341. At this time, the two rotating columns 342 will be pulled closer to each other. At this time, the two first arc-shaped plates 311 can be spliced ​​together and mutually squeezed and positioned. After the two second arc-shaped plates 321 are stuck on the outer wall of the corresponding collar 331, they can also be spliced ​​together and mutually squeezed and positioned by the insertion and screwing of the connecting mechanism 34. After positioning is completed, the positions of the first shaping mechanism 31 and the second shaping mechanism 32 can be adjusted by adjusting the position of the positioning mechanism 33 to meet the subsequent shaping operation of the inclined side of the workpiece 5.

[0071] When the first shaping mechanism 31 experiences localized wear or damage, or when shaping workpieces 5 of different shapes, and it is necessary to disassemble the first shaping mechanism 31 separately, it is only necessary to screw on the connecting mechanism 34 corresponding to the first arc plate 311 separately to remove the connecting mechanism 34 from the two first arc plates 311. Then, the two first arc plates 311 can be removed from the corresponding collars 331. The second shaping mechanism 32 does not need to be disassembled or moved, which reduces the difficulty and complexity of operation.

[0072] In addition, both first arc plates 311 are provided with contoured chamfer structures to facilitate the shaping of the beveled edge of workpiece 5. Furthermore, both second arc plates 321 have guide surfaces 323 at one end. Since the beveled edge of workpiece 5 may expand outward or contract inward, the contoured chamfer on the first arc plate 311 can shape the outwardly expanding beveled edge, while the inwardly contracting beveled edge is blocked and shaped by the cooperation of the second arc plate 321 and the corresponding guide surface 323. The beveled edge of workpiece 5 is guided by the guide surface 323 and further limited and blocked by the side wall of the second arc plate 321, so that the beveled edge of workpiece 5 can move between the first arc plate 311 and the second arc plate 321 for shaping.

[0073] If the second arc plate 321 is set to the shape of the first arc plate 311, an additional drive is required, which will greatly increase the cost. If the second arc plate 321 is made into a concave contour structure according to the shape of the first arc plate 311, the inclined side of the workpiece 5 will only contact the edge of the second arc plate 321, and the concave contour structure will have no effect.

[0074] Therefore, guide surfaces 323 are provided at one end of each of the two second arc-shaped plates 321 for auxiliary limiting and blocking. An auxiliary component 4 is installed on one side of the drive component 2. After the workpiece 5 passes through the shaping component 3, the auxiliary component 4 is used to assist in shaping the inner wall of the inclined side of the workpiece 5. The specific structure of the auxiliary component 4 is as follows:

[0075] See Figure 3 Two fixed blocks 41 are installed on one side of the bearing plate. The bottom of the two fixed blocks 41 is rotatably connected to a swing plate 42. The bottom end of the swing plate 42 is rotatably connected to a vertical rod 43. A tapered tube 44 is installed on the outer wall of the vertical rod 43. By adjusting the angle of the two swing plates 42, the distance between the two vertical rods 43 can be adjusted according to the inner diameter width of the workpiece 5, so that the tapered tube 44 can fit against the inclined side wall of the workpiece 5. The tapered tube 44, together with the first arc plate 311 and the second arc plate 321, forms a complete shaping path for the workpiece 5. When the workpiece 5 reaches the position of the tapered tube 44, the tapered tube 44 further shapes the inner side of the inclined side. After passing through the auxiliary component 4, the workpiece 5 completes the overall shaping operation.

[0076] Example 4: Online shaping method for aluminum profiles, using the online shaping device for aluminum profiles as described above, includes the following steps:

[0077] S1. The shaping component 3 is fitted according to the workpiece 5 and installed on the swing mechanism 234. Then, the height of the ball joint mechanism 233 is adjusted by rotating the handle 231 and the lifting screw 232. After that, the positions of the two sets of auxiliary components 4 are adjusted so that the shaping component 3 and the auxiliary components 4 cooperate to form a shaping path that is compatible with the workpiece 5.

[0078] The more specific steps in S1 are as follows:

[0079] S11. Install the first shaping mechanism 31 and the second shaping mechanism 32 of the workpiece 5 on the corresponding collar 331, that is, put the two first arc plates 311 onto the outer side wall of the corresponding collar 331. Then, insert the rotating column 342 on the two frames 341 into the positioning hole on the side wall of the first arc plate 311, and connect the two first arc plates 311 with the same connecting mechanism 34.

[0080] S12. After insertion, by rotating the frame 341, the length of the adjusting screw 344 inserted into the frame 341 changes, thereby adjusting the overall length of the connecting mechanism 34, that is, the distance between the two rotating columns 342 changes, and the two first arc plates 311 move closer to each other, thereby pressing and fitting onto the outer wall of the corresponding collar 331.

[0081] S13. The installation method of the second shaping mechanism 32 is the same as that of the first shaping mechanism 31, and the guide surface 323 on the second arc plate 321 is set towards the first arc plate 311. Then, by pushing the two collars 331 on the outer wall of the drive rod 2343, the overall position of the first shaping mechanism 31 and the second shaping mechanism 32 is adjusted, and the distance between the first arc plate 311 and the second arc plate 321 is adjusted, thereby setting a shaping path between the first arc plate 311 and the second arc plate 321.

[0082] S14. Then, by rotating the handle 231 and the lifting screw 232, the bottom end of the lifting screw 232 drives the ball joint mechanism 233 to slide within the corresponding gantry frame 22, thereby adjusting the overall height of the swing mechanism 234 and the shaping component 3, so that the shaping path between the first arc plate 311 and the second arc plate 321 can be adjusted according to the position of the inclined side of the workpiece 5.

[0083] S15. In addition, the L-shaped plate 2341 is pressed by rotating the extrusion screw 2344, causing the L-shaped plate 2341 and the drive rod 2343 to change angle, thereby adjusting the angle of the shaping path between the first arc plate 311 and the second arc plate 321. After the adjustment is completed, the hinge plate 2347 is locked by the first locking bolt 2346. This adjustment method further enables the shaping component 3 to adapt to the shaping of other shaped profiles.

[0084] S16. By adjusting the angle of the two swing plates 42, the distance between the two uprights 43 can be adjusted according to the inner diameter width of the workpiece 5, so that the tapered tube 44 can fit against the inclined side wall of the workpiece 5. The tapered tube 44, together with the first arc plate 311 and the second arc plate 321, forms a complete shaping path for the workpiece 5.

[0085] S2. Then, the workpiece 5 is placed on top of the roller conveyor mechanism 1, and the roller conveyor mechanism 1 drives the workpiece 5 to move forward in the direction of the shaping component 3 to prepare for the shaping operation.

[0086] The more specific steps of S2 are as follows:

[0087] S21. The opening of the workpiece 5 is set upward, and the workpiece 5 is driven to move as a whole by the roller conveyor mechanism 1. The inclined edge of the workpiece 5 is sent to the position between the corresponding first arc plate 311 and the second arc plate 321 for shaping.

[0088] S3. When the workpiece 5 approaches the position of the shaping component 3, the swing mechanism 234 drives the shaping component 3 to rotate as a whole. When the workpiece 5 reaches the position of the shaping component 3, the rotating shaping component 3 squeezes and shapes the inclined edge of the workpiece 5, causing the inclined edge of the workpiece 5 to be shaped. When the workpiece 5 reaches the position of the auxiliary component 4, the auxiliary component 4 further shapes the inner side of the inclined edge. After the workpiece 5 passes through the auxiliary component 4, the overall shaping operation is completed.

[0089] The more specific steps for S3 are as follows:

[0090] S31. When the workpiece 5 approaches the position of the shaping component 3, the L-shaped plate 2341 drives the drive rod 2343 and the shaping component 3 to rotate as a whole. When the inclined edge of the workpiece 5 reaches the position between the corresponding first arc plate 311 and second arc plate 321, the rotating first shaping mechanism 31 and second shaping mechanism 32 squeeze and shape the inclined edge of the workpiece 5.

[0091] S32. When the workpiece 5 reaches the position of the tapered tube 44, the tapered tube 44 further performs secondary shaping on the inner side of the inclined side, and the workpiece 5 completes the overall shaping operation after passing through the auxiliary component 4.

[0092] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
