The top support frames on both sides can assist the two ends of the substrate body to apply an upward thrust. On the one hand, it can expand the plastic deformation area of ​​the substrate body, reduce the springback of the substrate body after bending, and avoid the surface of the substrate body from being pressed and having dents or scratches.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments: Please see Figures 1-8 In this embodiment of the invention, an aluminum alloy sheet bending device based on tension clamp production includes a feeding base plate 1, a plurality of feeding rollers 7 are rotatably connected to the top of the feeding base plate 1, and a substrate body 6 is conveyed on the top of the feeding base plate 1. A protective frame 2 is fixed above the feeding base plate 1, and a cutting tool 4 and a bending tool 3 are respectively assembled inside the protective frame 2, which are used to cut and bend the conveyed substrate body 6 respectively. Specifically, each of the multiple feeding rollers 7 has a sprocket sleeved at its end, and the transmission operation is achieved through the cooperation of the drive chain 701. The multiple feeding rollers 7 are divided into three groups, respectively set between the cutting station and the bending station, and on both sides of the cutting station and the bending station. Each group of feeding rollers 7 is driven by a separate motor, which is not shown in the figure. The multiple feeding rollers 7 are installed at the same height, as shown in the figure. Figures 1-4 The tops of the multiple feeding rollers 7 extend slightly beyond the top surface of the feeding substrate 1, so that when the substrate body 6 is placed above the feeding substrate 1, the multiple operating feeding rollers 7 can complete the conveying operation of the substrate body 6. Specifically, the cutting station is located directly below the cutting tool 4, and the bending station is located directly below the bending tool 3. The protective frame 2 is equipped with multiple existing position sensors to monitor the conveying position of the substrate body 6 in real time, ensuring the cutting and bending accuracy.

[0023] In specific operation, the feeding roller 7 runs, which can transport the substrate body 6 located above the feeding substrate 1 to the cutting station, and complete the cutting of the substrate body 6 with the cooperation of the cutting tool 4. The cut substrate body 6 can reach the bending station with the running of the feeding roller 7, and complete the bending operation of the substrate body 6 with the cooperation of the bending tool 3. In this embodiment of the invention, a rectangular slot 8 is provided inside the feeding substrate 1, and a bending die 10 is assembled inside the rectangular slot 8. The bending die 10 is installed directly below the bending cutter 3. A top support frame 11 is provided on both sides of the top of the bending die 10. The top support frame 11 is used to support the conveyed substrate body 6 and is deflected by force during the bending process to support the side of the bent substrate body 6. Specifically, the bending die 10 is replaceable and can be replaced according to the requirements of different bending angles. A base plate 9 is fixedly installed at the bottom of the rectangular slot 8, and a load-bearing plate frame 901 is fixedly installed at the top of the base plate 9. The bending die 10 and the load-bearing plate frame 901 are slidably connected. A stop bar 902 is assembled at the end of the load-bearing plate frame 901. The stop bar 902 is used to limit the bending die 10. Specifically, when replacing the bending die 10, the limiting of the bending die 10 can be removed by disassembling the stop bar 902. Then, the bending die 10 can be pulled out for replacement and the limiting can be re-established by the stop bar 902. The stop bar 902 is connected to the load-bearing plate frame 901 by a thread. The disassembly of the stop bar 902 can be completed by rotating it. During the operation, as the substrate body 6 reaches the bending station, its bending position is directly below the bending cutter 3. At this time, the substrate body 6 can be supported by the two top support frames 11. The bending position of the substrate body 6 is located at the center between the two top support frames 11. As the bending cutter 3 moves down and contacts the substrate body 6, pressing the substrate body 6 into the bending die 10, it can drive the two top support frames 11 to deflect simultaneously, keeping them in contact with the outer surface of the substrate body 6, until the substrate body 6 is pressed into the bending die 10 to complete the bending operation. During the process of the bending cutter 3 moving down to apply pressure to the bending position of the substrate body 6, the top support frames 11 on both sides can assist in applying upward thrust to both ends of the substrate body 6. On the one hand, this can expand the plastic deformation area of ​​the substrate body 6, reduce the springback of the substrate body 6 after bending, and prevent the surface of the substrate body 6 from being dented or scratched due to pressure. On the other hand, the top support frames 11 can complete the bearing of the substrate body 6, realize the continuous conveying and processing of the substrate body 6, and facilitate the automatic lifting of the bent substrate body 6, which is convenient for subsequent material conveying operations. Specifically, a gap is left between the two top support frames 11. When the bending cutter 3 moves down to apply pressure to the substrate body 6, the two top support frames 11 can be subjected to force and diffract the corresponding limiting shaft 1101 to rotate. In this embodiment of the invention, both ends of the rectangular slot 8 are slidably connected to sliding frames 13, and the top of each of the two sliding frames 13 is equipped with an adjusting feeding frame 14. The inner sides of each of the two adjusting feeding frames 14 are rotatably connected to a feeding belt 1402, which is used to guide and adjust the substrate body 6 and to transport it. Specifically, the adjustable feeder 14 is used to limit and guide the substrate body 6 of different widths, and at the same time, it makes fine adjustments to the position of the substrate body 6 when it reaches the bending position to ensure bending accuracy.

[0024] Specifically, the top support frame 11 has a rotatable limiting shaft 1101 inside, and a torsion spring 1102 is sleeved at the end of the limiting shaft 1101. Both ends of the limiting shaft 1101 are slidably connected to limiting side plates 12. The limiting side plates 12 are fixedly installed inside the rectangular slot 8. A support spring 1103 is fixedly connected between the end of the limiting shaft 1101 and the inner wall of the limiting side plate 12. A limiting screw 1104 is assembled inside the limiting side plate 12, and the limiting screw 1104 meshes with the limiting side plate 12. Specifically, the top support frame 11 is initially parallel to the horizontal plane through the cooperation of the limiting shaft 1101 and the torsion spring 1102. When the bending cutter 3 moves down to apply pressure to the substrate body 6, the top support frame 11 can rotate along the corresponding limiting shaft 1101 under force. At this time, the torsion spring 1102 stores force, so that the top surface of the top support frame 11 and the bottom of the substrate body 6 always remain in contact. When the bending cutter 3 continues to move down to press the substrate body 6 into the bending mold 10, the top support frame 11 can be driven by force to slide the limiting shaft 1101 inside the corresponding limiting side plate 12, compressing the corresponding support spring 1103. Specifically, the limiting side plate 12 allows the limiting shaft 1101 to slide inside it, thus adapting to different bending angle requirements. The limiting screw 1104 installed inside the limiting side plate 12 is used to limit the sliding distance of the limiting shaft 1101. In specific operation, the length of the limiting screw 1104 inserted into the corresponding limiting side plate 12 is adjusted by rotating the limiting screw 1104, so that the limiting shaft 1101 stops after contacting the end of the limiting screw 1104 when sliding inside the limiting side plate 12. That is, the longest distance that the limiting shaft 1101 slides inside the limiting side plate 12 is the distance between the end of the limiting screw 1104 and the outer surface of the limiting shaft 1101. The initial position of the limiting shaft 1101 is located at one end of the inner side of the limiting side plate 12, and is supported by the supporting spring 1103. During operation, the limiting screw 1104 is turned according to the bending angle of the substrate body 6, and the longest distance of the limiting shaft 1101 is adjusted. As the bending cutter 3 moves down and contacts the substrate body 6, it drives the two top support frames 11 to rotate along the corresponding limiting shaft 1101. At the same time, it can drive the limiting shaft 1101 to slide inside the corresponding limiting side plate 12 until the limiting shaft 1101 contacts the end of the limiting screw 1104 and stops. The bending cutter 3 presses the substrate body 6 into the bending mold 10 to complete the bending operation. After the bending is completed, the bending cutter 3 moves up and resets. At this time, the limiting shaft 1101 can return to the initial position through the cooperation of the support spring 1103. The top support frame 11 rotates through the reset force of the torsion spring 1102, pushing the bent substrate body 6 upward and separating it from the bending mold 10. Specifically, both top support frames 11 are flush with the horizontal plane. Multiple through holes are opened at the top of each top support frame 11, and annular positioning frames 16 are fixedly installed inside each through hole. A sealing sliding column 1601 is slidably connected inside the annular positioning frame 16. Multiple air inlet channels 1602 are symmetrically opened inside the sealing sliding column 1601. The top of the sealing sliding column 1601 is conical, and a sealing ring 1603 is fixedly installed on the outer side of the sealing sliding column 1601. Multiple return springs 1604 are fixedly installed between the bottom of the sealing sliding column 1601 and the bottom of the annular positioning frame 16. Both top support frames 11 have internal cavities, and the multiple through holes communicate with the cavities. A negative pressure device is fixedly installed inside the rectangular slot 8, and the negative pressure device is connected to the two top support frames 11 via a flexible hose. Specifically, the annular positioning frame 16 is used to achieve adsorption and positioning of the substrate body 6, further improving bending accuracy. The top of the annular positioning frame 16 is flush with the corresponding top support frame 11. The tapered end of the sealing sliding column 1601 extends beyond the top of the annular positioning frame 16. When the sealing sliding column 1601 is in the initial position, the sealing ring 1603 installed on the outside can be kept in contact with the bottom of the annular positioning frame 16 through the cooperation of multiple return springs 1604, so that the cavity left inside the top support frame 11 can be kept sealed. When the sealing sliding column 1601 slides down inside the corresponding annular positioning frame 16, it can simultaneously drive the sealing ring 1603 to move down. As the sealing ring 1603 separates from the bottom of the annular positioning frame 16, external gas can enter the cavity through multiple air intake channels 1602. The negative pressure device is connected to the two top support frames 11 via flexible hoses, which can avoid affecting the rotation of the top support frames 11. At the same time, the operation of the negative pressure device can extract the air inside the top support frames 11 through the flexible hoses. The flexible hoses are existing connecting parts and are not shown in the figure. In actual operation, when the cut substrate body 6 reaches the bending station, it can be positioned above multiple annular positioning frames 16. At this time, the substrate body 6 can press down multiple corresponding sealing sliding columns 1601. First, the position of the substrate body 6 is finely adjusted by adjusting the feeding frame 14. After the adjustment is completed, the negative pressure device can be used to perform adsorption positioning of the bottom of the substrate body 6 through the cooperation of the corresponding annular positioning frames 16 and sealing sliding columns 1601 until the bending cutter 3 moves down and contacts the top of the substrate body 6. Therefore, it can be used to achieve pre-positioning for substrate bodies 6 of different widths, further improving bending accuracy.

[0025] Specifically, telescopic frames 501 are connected between the top ends of the cutting blade 4 and the bending blade 3 and the inner side of the protective frame 2, and drive cylinders 5 are connected to the top of the cutting blade 4 and the bending blade 3. Both drive cylinders 5 and telescopic frames 501 are existing devices. The drive cylinders 5 are controlled based on existing hydraulic cylinders and are used to drive the cutting blade 4 and the bending blade 3 to move down to achieve cutting and bending operations respectively. Specifically, positioning plates 401 are provided on both sides of the bottom of the cutting blade 4, and a positioning spring 402 is fixedly connected between the top of the positioning plate 401 and the cutting blade 4. The initial position of the positioning plate 401 extends beyond the bottom of the cutting blade 4. When the cutting blade 4 moves down, it can first drive the positioning plate 401 to move down and contact the substrate body 6, so that the positioning spring 402 is compressed, thereby completing the positioning of the substrate body 6 and ensuring the cutting effect. The positioning spring 402 is an existing device and will not be described in detail here.

[0026] Specifically, push cylinders 1301 are fixedly installed on both sides of the rectangular slot 8. The piston end of the push cylinder 1301 is connected to the corresponding sliding frame 13. The inside of the adjusting feed rack 14 is rotatably connected to the drive shaft 1401 on both sides and a servo motor 1403 is fixedly installed on the top. The feed belt 1402 is rotatably connected between the two corresponding drive shafts 1401. The servo motor 1403 is an existing forward and reverse motor. Its output end is connected to the corresponding drive shaft 1401 through a coupling, which will not be described in detail here. Specifically, connecting rods 15 are fixedly installed on both sides of the top of the sliding frame 13, and multiple connecting rings 1501 are fixed on both sides of the inside of the adjusting feeding frame 14. The connecting rings 1501 are slidably sleeved on the outside of the corresponding connecting rods 15, and multiple elastic connecting plates 1502 are fixed on the inside of the connecting rings 1501. Specifically, the push cylinder 1301 is controlled based on the existing cylinder controller to drive the sliding frame 13 to slide inside the rectangular slot 8 and adjust the distance between the two adjusting feed frames 14 to adapt to substrate bodies 6 of different widths. The sliding frame 13 is in the shape of a right angle. One end of the sliding frame 13 is slidably connected to the inner wall of the rectangular slot 8, and the other end of the sliding frame 13 is located on the top of the feeding substrate 1 and is slidably connected to the top of the feeding substrate 1. Specifically, the bottom of the feeding belt 1402 is flush with the top of the feeding substrate 1. The drive operation is achieved by the cooperation of the drive shaft 1401 and the servo motor 1403. During the operation, when the cut substrate body 6 is conveyed to the bending station through the feeding roller 7, the feeding belt 1402 can complete the traction and position fine adjustment of the substrate body 6 until the adjustment is completed and the bending operation is achieved by the bending cutter 3. Specifically, through the cooperation of multiple connecting rings 1501 and elastic connecting plates 1502, the adjustment feeding frame 14 and the corresponding sliding frame 13 can be adjusted slightly. During operation, as the top support frame 11 rotates and contacts the bottom of the adjustment feeding frame 14, it can drive the adjustment feeding frame 14 to move upward. At this time, the multiple elastic connecting plates 1502 inside the connecting rings 1501 are deformed by force until the top support frame 11 is reset and the adjustment feeding frame 14 is reset again, thus avoiding motion interference. refer to Figure 5 , Figure 6 The inner diameter of the connecting ring 1501 exceeds the diameter of the connecting rod 15. The inner side of the connecting ring 1501 and the connecting rod 15 are filled by multiple elastic connecting plates 1502. The elastic connecting plates 1502 are made of existing elastic rubber material, which will not be described in detail here. Specifically, through the cooperation of the sliding frame 13 and the adjusting feeding frame 14, when the cut substrate body 6 reaches the bending station, the position of the substrate body 6 can be finely adjusted by the running feeding belt 1402. When the top support frame 11 automatically pushes the bent substrate body 6 upward, the running feeding belt 1402 can complete the self-feeding output of the bent substrate body 6 without manual intervention, thus improving the ease of operation of the equipment.
