Description

Technical Field

[0001] This utility model relates to the field of bending device technology, specifically a bending device for metal products. Background Technology

[0002] In the field of metal product manufacturing, when processing aluminum profiles for building curtain walls, it is necessary to bend the aluminum profiles into suitable shapes to meet their functional and aesthetic requirements, thus requiring the use of a bending device.

[0003] Existing bending devices include a worktable and a bending mechanism. The top of the worktable is equipped with a conveying mechanism, a pressing mechanism, and a driving mechanism. The conveying mechanism conveys the material, the pressing mechanism limits the material, and the bending structure bends the material.

[0004] However, the aforementioned bending device still has some problems. In practical applications, the bending angle cannot be precisely controlled, resulting in the curtain wall panels not being able to be accurately spliced ​​and installed on the exterior of the building, causing the products to fail to meet quality requirements and thus wasting raw materials. Therefore, a metal product bending device is proposed to address the above problems. Utility Model Content

Several scale lines are equidistantly engraved on one side of the scale. A sliding groove is formed inside the top side of the scale. A positioning block is slidably installed inside the sliding groove. An indicator needle is installed on the bottom side of the positioning block. A groove is formed inside one side of the positioning block. A pressure sensor is assembled inside the groove. The pressure sensor is used to monitor the pressure of the sliding rod on the positioning block. Several limiting holes are equidistantly formed inside the scale and extending through the sliding groove. A locking screw is rotatably installed inside one of the limiting holes. One end of the locking screw abuts against the positioning block, thereby achieving precise control of the bending angle of the metal product and improving the processing quality of the metal product.

[0008] Preferably, a fixed plate is installed on the top side of the workbench, and a servo motor is installed on one side of the fixed plate. One end of the rotating shaft is connected to the output end of the servo motor. By controlling the rotation of the rotating shaft, the metal products are bent, thereby improving the processing quality and efficiency.

[0009] Preferably, a cylinder is installed on the top side of the fixing frame, an actuating rod is installed on the working end of the cylinder, and a pressing plate is installed on the bottom side of the actuating rod. The cylinder presses the metal product through the actuating rod and the pressing plate to ensure that the metal product remains stable during the bending process, avoids displacement, and improves the bending effect.

[0010] Preferably, a drive motor is installed on one side of the worktable, and a threaded rod is installed at the output end of the drive motor.

The stop plate cooperates with the support plate to fix one side of the metal product, forming a double fixation with the pressing plate, ensuring that the metal product will not move during bending, thereby improving processing accuracy and safety.

[0011] Preferably, a control panel is installed on the other side of the workbench. The control panel is electrically connected to the pressure sensor and the servo motor. The control panel is used for signal transmission from the pressure sensor and operation control of the servo motor and other electrical components to realize automated control of the device and improve operation convenience and processing efficiency.

[0012] The advantages of this utility model are:

[0023] Please see Figure 1-4 As shown, a metal product bending device includes a workbench 1. A scale 2 is installed on the upper edge of the workbench 1. An arc-shaped groove 3 is formed inside the scale 2. A rotating shaft 4 is rotatably installed inside the scale 2. A connecting rod 5 is installed at one end of the rotating shaft 4. A sliding rod 6 is installed at one end of the connecting rod 5. The sliding rod 6 is slidably installed inside the arc-shaped groove 3. Several scale lines 7 are equidistantly engraved on one side of the scale 2. A sliding groove 8 is formed inside the top side of the scale 2. A positioning block 9 is slidably installed inside the slide 8. An indicator needle 10 is installed on the bottom side of the positioning block 9. A groove 11 is opened inside one side of the positioning block 9. A pressure sensor 12 is installed inside the groove 11. The pressure sensor 12 is used to monitor the pressure of the slide rod 6 on the positioning block 9. A number of limiting holes 13 are opened at equal intervals inside the dial 2 and the slide 8. A locking screw 14 is rotatably installed inside one of the limiting holes 13. One end of the locking screw 14 abuts against the positioning block 9.

[0024] A mounting bracket 15 is installed on the top side of the workbench 1. The dial 2 is fixedly installed on one side of the bottom end of the mounting bracket 15. A support plate 16 is installed on one side of the mounting bracket 15. Mounting plates 17 are installed on both sides of the support plate 16. The other end of the rotating shaft 4 passes through the mounting plate 17. A bending plate 18 is installed on the outer side of the rotating shaft 4. A mounting plate 19 is installed on the top side of the workbench 1. A servo motor 20 is installed on one side of the mounting plate 19. One end of the rotating shaft 4 is connected to the output end of the servo motor 20. A control panel 30 is installed on the other side of the workbench 1. In actual application, during operation... The inability to precisely control the bending angle results in the curtain wall panels not being able to be accurately spliced ​​and installed on the building facade, leading to products that do not meet quality requirements and thus wasting raw materials. First, the operator loosens the locking screw 14. With the cooperation of the scale line 7, the positioning block 9 drives the indicator needle 10 to slide inside the slide groove 8. According to the required bending angle, by moving the positioning block 9, the indicator needle 10 is made to point to the corresponding scale line 7 position. After reaching the predetermined angle position, the locking screw 14 is moved into the appropriate limiting hole 13. By rotating the locking screw 14, one end of it is pressed against the positioning block 9, thereby fixing the position of the positioning block 9.

[0025] After fixing, when bending is performed, the servo motor 20 is started. The output end of the servo motor 20 drives the rotating shaft 4 to rotate. As the rotating shaft 4 continues to rotate, the slide rod 6 gradually approaches and contacts the positioning block 9. When the slide rod 6 contacts the positioning block 9, the pressure sensor 12 receives the pressure signal and transmits the signal to the control panel 30. The control panel 30 controls the servo motor 20 to stop working. At this time, the rotating shaft 4 drives the bending plate 18 to rotate to a suitable bending angle, completing the bending operation of the aluminum profile plate. This achieves precise control of the bending angle of metal products, improving processing quality and efficiency. The specific model of the pressure sensor 12 is HBM-C16i.

[0026] Please see Figure 1 , 2 As shown in Figures 3 and 5, a cylinder 21 is installed on the top side of the fixing frame 15, an actuating rod 22 is installed on the working end of the cylinder 21, and a pressing plate 23 is installed on the bottom side of the actuating rod 22.

[0027] A drive motor 24 is installed on one side of the workbench 1. A threaded rod 25 is installed at the output end of the drive motor 24. A slide rail 26 is provided inside one end of the workbench 1. A sliding block 27 is slidably installed inside the slide rail 26. A threaded hole is provided inside the sliding block 27. One end of the threaded rod 25 passes through the threaded hole and is rotatably installed inside the slide rail 26. A support rod 28 is installed on the top side of the sliding block 27. A stop plate 29 is installed at one end of the support rod 28. The stop plate 29 contacts the support plate 16 but is not connected. During operation, in the field of metal product manufacturing, for When processing aluminum profiles for building curtain walls, the aluminum profiles need to be bent into suitable shapes to meet their functional and aesthetic requirements. Therefore, a bending device is required. To ensure stability during bending, the aluminum profile is placed on a support plate 16, with the bending position symmetrical between the support plate 16 and the bending plate 18. The cylinder 21 is activated, and the actuating end of the cylinder 21 pushes the actuating rod 22 downward. The pressing plate 23 installed on the bottom side of the actuating rod 22 presses down on the aluminum profile, ensuring that the aluminum profile remains stable during subsequent bending and avoiding displacement.

[0028] At the same time, the drive motor 24 is turned on, and the output end of the drive motor 24 drives the threaded rod 25 to rotate, which drives the sliding block 27 to slide inside the slide rail 26, and drives the support rod 28 and the abutment plate 29 to move as well, until the abutment plate 29 fixes one side of the aluminum profile, forming a double fixation with the pressing plate 23, further ensuring that the aluminum profile will not move during the bending process, improving processing accuracy and safety.

[0029] Working principle: When bending aluminum profiles, in order to ensure stability during bending, the aluminum profile is placed on the support plate 16, so that the bending position is symmetrical between the support plate 16 and the bending plate 18. The cylinder 21 is activated, and the actuating end of the cylinder 21 pushes the actuating rod 22 downward. The pressing plate 23 installed on the bottom side of the actuating rod 22 presses down on the aluminum profile, ensuring that the aluminum profile remains stable during the subsequent bending process and avoiding displacement.

[0030] At the same time, the drive motor 24 is turned on. The output end of the drive motor 24 drives the threaded rod 25 to rotate, which drives the sliding block 27 to slide inside the slide rail 26. This causes the support rod 28 and the abutment plate 29 to move as well, until the abutment plate 29 fixes one side of the aluminum profile, forming a double fixation with the pressing plate 23. This further ensures that the aluminum profile will not move during the bending process, improving processing accuracy and safety.

[0031] First, the operator loosens the locking screw 14. With the cooperation of the scale line 7, the positioning block 9 drives the indicator needle 10 to slide inside the slide groove 8. According to the required bending angle, the positioning block 9 is moved to make the indicator needle 10 point to the corresponding scale line 7. After reaching the predetermined angle position, the locking screw 14 is moved into the appropriate limiting hole 13. By rotating the locking screw 14, one end of it is pressed against the positioning block 9, thereby fixing the position of the positioning block 9.

[0032] After fixing, when bending is performed, the servo motor 20 is started. The output end of the servo motor 20 drives the rotating shaft 4 to rotate. As the rotating shaft 4 continues to rotate, the slide rod 6 gradually approaches and contacts the positioning block 9. When the slide rod 6 contacts the positioning block 9, the pressure sensor 12 receives the pressure signal and transmits the signal to the control panel 30. The control panel 30 controls the servo motor 20 to stop working. At this time, the rotating shaft 4 drives the bending plate 18 to rotate to a suitable bending angle, completing the bending operation of the aluminum profile plate. This achieves precise control of the bending angle of metal products, improving processing quality and efficiency. The specific model of the pressure sensor 12 is HBM-C16i.
