Description

Technical Field

[0001] This invention relates to the field of sheet metal bending technology, specifically to a fully automatic bending machine and method for aluminum profile production and processing. Background Technology

[0002] Hydraulic bending is a mechanical device that uses a hydraulic system to control the frame and mold, allowing aluminum profiles to bend into the desired shape at specific locations. Its working principle mainly relies on the power of the hydraulic system. The high-pressure oil in the hydraulic system pushes the piston of the cylinder, which in turn drives the mold to bend the sheet metal, thereby improving the utilization effect of the strip. It is mainly used in industries such as shipbuilding, automobiles, machinery, and electrical appliances.

[0003] In existing solutions, aluminum profiles are conveyed to the bending position, where the middle of the profile is first fixed, and then the sides are bent. However, this method is usually only suitable for aluminum profiles of a single thickness or width. This processing method is simple in structure and suitable for batch processing of standard-sized aluminum profiles, but it lacks versatility. After the aluminum profile is bent, its formed structure is usually non-planar and fits tightly against the worktable. Especially when the bending angle is large or the springback after bending is small, there is almost no gap between the bottom of the component and the worktable. It is difficult for manual or automatic devices to quickly remove the component from the worktable. If it is forcibly lifted, it is easy to cause deformation or scratches to the profile, affecting the quality of subsequent processes. Summary of the Invention

[0018] A method for producing and processing aluminum profiles using a fully automatic bending machine, the method comprising the following steps:

[0019] Step 1: Thick aluminum profiles enter the pressure roller unit and material loading unit in the connecting seat and the stop seat until the end of the aluminum profile enters between the upper and lower clamping plates, pressing one end of the aluminum profile, while the pressure roller unit in the connecting seat presses the other end of the aluminum profile.

[0020] Step 2: The thinner aluminum profile rolls on the circular pad on the lower roller. At this time, the horizontal plate is driven to rise and become flush with the upper surface of the circular pad under the push of the electric push rod. The supporting plate rises synchronously for the thicker aluminum profile to pass through. Then, the hydraulic cylinder pushes the pressure plate upward into the bending groove to bend the aluminum profile upward.

[0021] Step 3: After bending, both ends of the aluminum profile are between the bearing plate and the upper pressure strip. The rotation of the gear drives the upper and lower racks to work. The racks drive the connecting seat and the stop seat to move away from each other. At this time, the upper pressure strip detaches from the upper part of the aluminum profile.

[0022] Step 4: The electric pusher pushes the push plate to detach the bent aluminum profile from the bending frame. At this time, the height of the aluminum profile is higher than the height of the second conveyor belt. Then, the push end of the push cylinder pushes the second conveyor belt to move below the aluminum profile. When the push plate moves downward, it causes the bent end of the aluminum profile to contact the surface of the second conveyor belt. After that, the push cylinder resets, causing the second conveyor belt to move closer to the end of the first conveyor belt, thereby realizing the transfer and conveying of the bent aluminum profile.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. By setting up a pressure roller unit and a material-carrying unit, the horizontal plate and the lower roller are initially at the same height. When a wider aluminum profile is placed in the lower roller, the height of the horizontal plate is adjusted, causing the telescopic rod and the upper pressure bar to rise together. Then, the aluminum profile enters between the horizontal plate and the upper pressure bar. At this time, the telescopic rod and the second spring are in an extended state. After the upper roller moves, it changes the vertical distance between itself and the lower roller to accommodate aluminum profiles of different thicknesses. It can also be placed according to the width of the aluminum profile. The corresponding bearing plate moves vertically on the inner wall of the bending frame. The upper roller in the connecting seat and the stop seat presses against the upper surface of the aluminum profile. The two ends of the aluminum profile are pressed tightly together, and then the hydraulic cylinder pushes the pressure plate into the bending groove to bend the aluminum profile. After bending, the electric push rod pushes the push plate to rise. The push plate lifts the bent aluminum profile and leaves the outer wall of the pressure plate. At this time, the height of the aluminum profile is higher than the height of the second conveyor belt. Then, the push cylinder pushes the second conveyor belt to move below the aluminum profile. When the push plate moves downward, it drives the bent end of the aluminum profile to contact the surface of the second conveyor belt. The second conveyor belt starts to drive. At the same time, the push cylinder resets so that the end of the second conveyor belt is close to the end of the first conveyor belt, thereby realizing the transfer and conveying of the bent aluminum profile.

[0025] 2. The aluminum profile to be bent reaches the ends of the upper and lower clamping plates via the lower roller or circular pad. With the help of the inclined surface design, the aluminum profile is guided into the gap between the upper and lower clamping plates. At this time, the upper clamping plate presses the upper spring three upward, while the lower clamping plate presses the lower spring three downward, thereby inserting the end of the aluminum profile between the upper and lower clamping plates to accommodate the positioning of aluminum profiles of different widths.

[0026] 3. After bending is completed, the connecting seat and the stop seat move away from each other at the same time, releasing the restriction on the end of the aluminum profile. At this time, the bent aluminum profile rests on the two bearing plates, which facilitates the subsequent lifting of the bent aluminum profile. Attached Figure Description

[0036] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0037] Please see Figures 1-7As shown, this invention provides a fully automatic bending machine for aluminum profile production and processing, including a base 1. A bending frame 2 supported by a bracket is arranged in the middle of the top surface of the base 1. Connecting seats 3 and stop seats 4 are movably connected to both sides of the bending frame 2, respectively. A bending groove 16 is provided on the bottom surface of the inner cavity of the bending frame 2, and a pressure plate 7 for bending the sheet material is arranged below the bending frame 2 by a hydraulic cylinder. A push plate 37 pushed by an electric push rod 2 is embedded in the upper surface of the pressure plate 7. A transmission and conveying assembly is arranged directly above the bending groove 16. The transmission and conveying assembly includes a first conveyor belt 10, and a second conveyor belt 11 is movably arranged at one end of the first conveyor belt 10. Vertically sliding bearings are provided at the ends of the inner walls on both sides of the bending frame 2. The inner cavities of the support plate 25, connecting seat 3, and stop seat 4 are all equipped with feeding components for plates of different thicknesses to pass through. The feeding components include a pressure roller unit and a material loading unit. The pressure roller unit includes an upper roller 19 movably disposed on the inner wall of the connecting seat 3 and stop seat 4, and a lower roller 17 rotatably disposed below the upper roller 19. The material loading unit includes a horizontal plate 29 that is lifted and lowered on the inner wall of the connecting seat 3 and stop seat 4. A telescopic rod 31 is provided at the upper end of the horizontal plate 29, and the horizontal plate 29 is flush with the upper surface of the lower roller 17. An upper pressure bar 21 is connected to the top of the telescopic rod 31, and a spring 32 is sleeved on the outside of the telescopic rod 31. The end of the upper pressure bar 21 is vertically collinear with the end face of the support plate 25.

[0038] Aluminum profiles of different thicknesses can pass through the pressure roller unit and the loading unit. Initially, the horizontal plate 29 is connected to the bearing support plate 25, and the height of the horizontal plate 29 and the lower roller 17 are consistent. When a wider aluminum profile is placed in the lower roller 17, the height of the horizontal plate 29 is adjusted, which drives the telescopic rod 31 and the upper pressure bar 21 to rise together. Then the aluminum profile enters between the horizontal plate 29 and the upper pressure bar 21. At this time, the telescopic rod 31 and the spring 32 are in the extended state. The upper roller 19 in the pressure roller unit can be adjusted vertically, while the position of the lower roller 17 remains unchanged and can rotate. After the upper roller 19 moves, it changes the vertical distance between itself and the lower roller 17 to accommodate the passage of aluminum profiles of different thicknesses. It can also be placed according to the width of the aluminum profile. The corresponding bearing support plate 25 moves vertically on the inner wall of the bending frame 2. Then the aluminum profile enters the inner wall of the stop 4 and is locked, and is controlled by the upper roller 19 in the connecting seat 3 and the stop 4. The two ends of the upper surface of the aluminum profile are tightly pressed together. Then, the hydraulic cylinder pushes the pressure plate 7 into the bending groove 16 to bend the aluminum profile. During the bending process, the end of the aluminum profile that is in contact with the pressure plate moves closer to the horizontal plate 29 and the upper pressure strip 21, thereby realizing the bending of the aluminum profile. After bending, the connecting seats 3 and the stop seats 4 on both sides of the bending frame 2 move away respectively. At this time, the upper pressure strip 21 leaves the upper end surface of the bent aluminum profile. The electric push rod pushes the push plate 37 to rise. The push plate 37 lifts the bent aluminum profile and leaves the outer wall surface of the pressure plate 7. At this time, the height of the aluminum profile is higher than the height of the second conveyor belt 11. Then, the push cylinder 13 pushes the second conveyor belt 11 to move to the bottom of the aluminum profile. When the push plate 37 moves downward, it drives the bent end of the aluminum profile to contact the surface of the second conveyor belt 11. After that, the push cylinder 13 resets, so that the second conveyor belt 11 is close to the end of the first conveyor belt 10, thereby realizing the transfer and conveying of the bent aluminum profile.

[0039] See Figure 2 and Figure 5 As shown, the inner wall surfaces of the connecting seat 3 and the stop seat 4 are provided with guide grooves 15 on the side adjacent to the bending frame 2. An electric push rod 30 is installed on the bottom surface of the inner cavity of the guide groove 15. The end faces of the upper pressure strip 21 and the horizontal plate 29 are provided with protrusions 22. The protrusions 22 slide against the guide groove 15. The pushing end of the electric push rod 30 is connected to the bottom surface of the horizontal plate 29.

[0040] The inner wall of the guide groove 15 is provided with an inwardly recessed sliding groove, and both sides of the protrusion 22 are provided with limit posts 23. The sliding seat connected to the limit post 23 is slidably set with the sliding groove.

[0041] The height of the horizontal plate 29 is adjusted by the electric push rod 30, so that the horizontal plate 29 can adapt to different height positions of the lower roller 17 and accommodate the passage of aluminum profiles of different widths. The protrusions 22 on the end faces of the horizontal plate 29 and the upper pressure strip 21 slide within the guide groove 15, and the sliding of the limiting post 23 within the slide groove improves the stability of the horizontal plate 29 and the upper pressure strip 21 during sliding. The movement of the upper roller 19 changes its distance from the lower roller 17, accommodating the entry of aluminum profiles of different thicknesses.

[0042] See Figure 2 and Figure 5 As shown, the pressure roller unit also includes a movable plate 18 disposed on the inner wall of the connecting seat 3 or the stop seat 4. The end face of the upper roller 19 is rotatably disposed with the movable plate 18. Circular pads 20 are disposed on the outer surface ends of both the upper roller 19 and the lower roller 17.

[0043] A tenon is provided on one side of the horizontal plate 29, and a mortise is provided on one side of the bearing plate 25 to cooperate with the tenon. The inner wall end of the bent frame 2 is provided with a guide groove 24 for sliding the bearing plate 25. A spring 26 is installed on the top surface of the inner cavity of the guide groove 24, and the end of the spring 26 is fixed to the upper surface of the bearing plate 25.

[0044] After the connecting seat 3 and the stop seat 4 are attached to the end face of the bending frame 2, the horizontal plate 29 and the bearing support plate 25 are snapped together. When the horizontal plate 29 rises, it drives the bearing support plate 25 to move together. Initially, the spring 26 is in a free state. At this time, the bearing support plate 25 is flush with the upper surface of the circular pad 20 on the lower roller 17. The aluminum profile rolls in contact with the circular pad 20 on the lower roller 17. After the horizontal plate 29 and the bearing support plate 25 are snapped together, the spring 26 is in an elastic tension state. At this time, the horizontal plate 29 is flush with the upper surface of the lower roller 17. The aluminum profile with a small width rolls on the lower roller 17.

[0045] See Figure 1 As shown, reinforcing blocks 12 are installed on both sides of conveyor belt 10 and conveyor belt 2 11. A reinforcing rod 14 is installed between two reinforcing blocks 12 on the same side. A propulsion cylinder 13 is installed on the surface of one of the reinforcing blocks 12. The pushing end of the propulsion cylinder 13 is fixed to the other reinforcing block 12 on the same side.

[0046] During operation, the bent aluminum profile is pushed upwards to a height higher than that of the second conveyor belt 11. Then, the push cylinder 13 pushes the second conveyor belt 11 to move below the aluminum profile. When the push plate 37 moves downwards, it causes the bent end of the aluminum profile to contact the surface of the second conveyor belt 11. Then, the second conveyor belt 11 begins to move. At the same time, the push cylinder 13 resets, causing the second conveyor belt 11 to move closer to the end of the first conveyor belt 10, thereby realizing the transfer and conveying of the bent aluminum profile. At this time, the push plate 37 resets to the upper surface of the pressure plate 7.

[0047] See Figure 6 As shown, a movable groove is provided on the inner wall of the stop 4. A fixed column 35 is vertically installed in the movable groove. An upper clamping plate 33 and a lower clamping plate 34 are slidably sleeved on the fixed column 35. The lower surface of the upper clamping plate 33 and the upper surface of the lower clamping plate 34 are both provided with inclined surfaces. Two springs 36 are sleeved on the outside of the fixed column 35. One spring 36 is located between the movable groove and the upper clamping plate 33, and the other spring 36 is located between the movable groove and the lower clamping plate 34. Wider aluminum profiles are rolled into the ends of the upper clamping plate 33 and the lower clamping plate 34 by the circular pad 20 on the lower roller 17. Smaller aluminum profiles are rolled to the ends of the upper clamping plate 33 and the lower clamping plate 34 by the lower roller 17. With the help of the inclined surface design, the aluminum profiles are guided into the space between the upper clamping plate 33 and the lower clamping plate 34. At this time, the upper clamping plate 33 presses the upper spring 36 upward, while the lower clamping plate 34 presses the lower spring 36 downward, thereby fixing the ends of the aluminum profiles.

[0048] See Figure 1 and Figure 3 As shown, the bending frame 2 is equipped with a gear 27 driven by a forward and reverse motor. The outer surface of the gear 27 meshes with two racks 28. The end of one rack 28 passes through one side surface of the bending frame 2 and is fixed to the end of the connecting seat 3. The end of the other rack 28 passes through the other side surface of the bending frame 2 and is fixed to the end of the stop 4.

[0049] Two limiting rods 6 are provided on the outer surface ends of both the connecting seat 3 and the stop seat 4. A limiting frame 5 is provided on the outer surface end of the bending frame 2 for the corresponding limiting rods 6 to slide through. Support columns 9 are installed on the lower surface of both the connecting seat 3 and the stop seat 4. A sliding groove 8 is provided on the upper surface of the base 1. A slider is slidably installed inside the sliding groove 8. The slider is fixed to the end of the support column 9.

[0050] Initially, the end faces of the connecting seat 3 and the stop seat 4 are in contact with the end face of the bending frame 2. After the aluminum profile is bent, the gear 27 starts to rotate and drives the upper and lower racks 28 to move in opposite directions. The connecting seat 3 connected to the upper rack 28 separates from the bending frame 2, while the stop seat 4 connected to the lower rack 28 separates from the bending frame 2. At this time, the connecting seat 3 and the stop seat 4 move away from each other. The connecting seat 3 and the stop seat 4 are supported by the support column 9 during movement, and the connecting seat 3 and the stop seat 4 are stably opened by the sliding of the limiting rod 6 within the limiting frame 5.

[0051] This invention provides a method for producing and processing aluminum profiles using a fully automatic bending machine, the method comprising the following steps:

[0052] Step 1: Thick aluminum profiles enter the pressure roller unit and material loading unit in the connecting seat 3 and the stop seat 4 until the end of the aluminum profile enters between the upper clamping plate 33 and the lower clamping plate 34, pressing one end of the aluminum profile, and the pressure roller unit in the connecting seat 3 presses the other end of the aluminum profile.

[0053] Step 2: The thin aluminum profile rolls on the circular pad 20 on the lower roller 17. At this time, the horizontal plate 29 is driven to rise and become flush with the upper surface of the circular pad 20 under the push of the electric push rod 30. The bearing plate 25 rises synchronously for the passage of the thick aluminum profile. Then, the hydraulic cylinder pushes the pressure plate 7 upward into the bending groove 16 to bend the aluminum profile upward.

[0054] Step 3: After bending, both ends of the aluminum profile are between the bearing support plate 25 and the upper pressure strip 21. The rotation of the gear 27 drives the upper and lower racks 28 to work. The racks 28 drive the connecting seat 3 and the stop seat 4 to move away from each other. At this time, the upper pressure strip 21 is separated from the upper part of the aluminum profile.

[0055] Step 4: The electric pusher 2 pushes the push plate 37 to detach the bent aluminum profile from the bending frame 2. At this time, the height of the aluminum profile is higher than the height of the second conveyor belt 11. Then, the push end of the push cylinder 13 pushes the second conveyor belt 11 to move below the aluminum profile. When the push plate 37 moves downward, it causes the bent end of the aluminum profile to contact the surface of the second conveyor belt 11. After that, the push cylinder 13 resets, so that the second conveyor belt 11 is close to the end of the first conveyor belt 10, thereby realizing the transfer and conveying of the bent aluminum profile.

[0056] In use, this invention, by setting up a pressure roller unit and a material-carrying unit, ensures that the horizontal plate 29 and the lower roller 17 are at the same height. When a wider aluminum profile is placed inside the lower roller 17, the horizontal plate 29 is raised, causing the telescopic rod 31 and the upper pressure bar 21 to rise together. The aluminum profile then enters between the horizontal plate 29 and the upper pressure bar 21. At this time, the telescopic rod 31 and the second spring 32 are in an extended state. After the upper roller 19 moves, it changes its vertical distance from the lower roller 17, accommodating the passage of aluminum profiles of different thicknesses. It can also be placed according to the width of the aluminum profile. The corresponding supporting plate 25 moves vertically on the inner wall of the bending frame 2, controlled by the upper support plate within the connecting seat 3 and the stop seat 4. Roller 19 presses the two ends of the upper surface of the aluminum profile tightly together. Then, the hydraulic cylinder pushes the pressure plate 7 into the bending groove 16 to bend the aluminum profile. After bending, the electric push rod 2 pushes the push plate 37 to rise. The push plate 37 lifts the bent aluminum profile and leaves the outer wall of the pressure plate 7. At this time, the height of the aluminum profile is higher than the height of the second conveyor belt 11. Then, the push cylinder 13 pushes the second conveyor belt 11 to move below the aluminum profile. When the push plate 37 moves downward, it drives the bent end of the aluminum profile to contact the surface of the second conveyor belt 11. After that, the push cylinder 13 resets so that the second conveyor belt 11 is close to the end of the first conveyor belt 10, thereby realizing the transfer and conveying of the bent aluminum profile.

[0057] The aluminum profile to be bent reaches the end of the upper clamping plate 33 and the lower clamping plate 34 via the lower roller 17 or the circular pad 20. With the help of the inclined surface design, the aluminum profile is guided into the gap between the upper clamping plate 33 and the lower clamping plate 34. At this time, the upper clamping plate 33 presses the upper spring 36 upward, while the lower clamping plate 34 presses the lower spring 36 downward, thereby inserting the end of the aluminum profile between the upper clamping plate 33 and the lower clamping plate 34 to accommodate the positioning of aluminum profiles of different widths.

[0058] After bending, the connecting seat 3 and the stop seat 4 move away from each other, releasing the restriction on the end of the aluminum profile. At this time, the bent aluminum profile rests on the two bearing plates 25, which facilitates the subsequent lifting of the bent aluminum profile.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

8. A method for producing and processing aluminum profiles using a fully automatic bending machine according to any one of claims 1-7, characterized in that, The method includes the following steps: Step 1: Thick aluminum profiles enter the pressure roller unit and material loading unit in the connecting seat (3) and the stop (4) until the end of the aluminum profile enters between the upper clamping plate (33) and the lower clamping plate (34), pressing one end of the aluminum profile, and the pressure roller unit in the connecting seat (3) presses the other end of the aluminum profile. Step 2: The thin aluminum profile rolls on the circular pad (20) on the lower roller (17). At this time, the horizontal plate (29) is driven to rise and become flush with the upper surface of the circular pad (20) under the push of the electric push rod (30). The bearing plate (25) rises synchronously for the thick aluminum profile to pass through. Then, the hydraulic cylinder pushes the pressure plate (7) upward into the bending groove (16) to bend the aluminum profile upward. Step 3: After bending, both ends of the aluminum profile are between the bearing plate (25) and the upper pressure strip (21). The rotation of the gear (27) drives the upper and lower racks (28) to work. The racks (28) drive the connecting seat (3) and the stop seat (4) to move away from each other.

Step 4: The electric pusher pushes the push plate (37) to separate the bent aluminum profile from the bending frame (2). At this time, the height of the aluminum profile is higher than the height of the second conveyor belt (11). Then, the push end of the push cylinder (13) pushes the second conveyor belt (11) to move to the bottom of the aluminum profile. When the push plate (37) moves downward, it drives the bent end of the aluminum profile to contact the surface of the second conveyor belt (11). Then the push cylinder (13) resets so that the second conveyor belt (11) and the end of the first conveyor belt (10) are close together, thereby realizing the transfer and conveying of the bent aluminum profile.
