Description

Technical Field

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

[0002] Metal plates are decorative panels made of metal. In the processing of plate heat exchangers and coolers, the metal plates need to be bent using a bending device, thus requiring a metal plate bending device.

[0003] A Chinese patent with authorization announcement number CN222268316U discloses a metal sheet bending device, including a base, four columns fixedly connected to the base, and a support plate fixedly connected to the top of the four columns. A placement platform is installed on the base, and a first pneumatic cylinder is installed on the support plate. In use, this utility model facilitates alternating between curved surface bending and right angle bending without the need to change equipment back and forth, thus completing the bending of curved surfaces and right angles of metal sheets and greatly improving bending efficiency.

[0004] However, the above solution still has some problems. When bending, the sheet metal is easily deflected by the lateral force, which causes the bending position to shift each time, thus reducing the bending accuracy of the metal sheet. Therefore, a metal sheet bending device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a metal plate bending device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a metal sheet bending device, including: a processing table, on which a sliding groove is formed; a first drive motor is installed on one side of the processing table; a connecting shaft is fixedly connected to the output end of the first drive motor; a bidirectional screw is fixedly connected to one end of the connecting shaft; one end of the bidirectional screw is rotatably connected to the inside of the processing table; a connecting frame is threaded onto the bidirectional screw; the connecting frame has an internal thread; the connecting frame is slidably connected to the inside of the sliding groove; a baffle is fixedly connected to one side of the connecting frame; and a rubber pad is fixedly connected to one side of the baffle. The rubber pad can reduce the impact force generated when the baffle moves towards the metal sheet, thereby avoiding dents on the bent side of the metal sheet.

[0007] Preferably, a second drive motor is installed inside the processing table, and a sector frame is fixedly connected to the output end of the second drive motor. A push rod is fixedly connected to the upper surface of one end of the sector frame. A connecting plate is rotatably connected inside the processing table. When the second drive motor is started, it can drive the sector frame to rotate, thereby simultaneously driving the push rod to rotate around the output shaft of the second drive motor.

[0008] Preferably, the lower surface of the connecting plate is provided with a force-receiving groove, the push rod is connected to the force-receiving groove in a transmission manner, an arc-shaped plate is fixedly connected to the lower surface of the connecting plate, and an anti-slip pad is fixedly connected to one side of the arc-shaped plate. Because the anti-slip pad can increase the friction between itself and the arc-shaped end of the fan-shaped frame, it can improve the transmission force of the fan-shaped frame.

[0009] Preferably, the arc-shaped end of the fan-shaped frame is connected to the anti-slip pad, and a limiting rod is fixedly connected to the upper surface of the connecting plate. The limiting rod is rotatably connected to the inside of the processing table. A connecting rod is provided inside the limiting rod, and an electromagnetic chuck is spherically hinged to one side of the connecting rod. The center position of the metal plate to be bent is attracted to the electromagnetic chuck, which can fix the position of the metal plate when bending, thereby reducing the offset caused by bending.

[0010] Preferably, a lower mold is provided on the upper surface of the processing table, a support frame is fixedly connected to the upper surface of the processing table, a cylinder is installed on the upper surface of the support frame, and an upper mold is fixedly connected to the telescopic end of the cylinder. When the cylinder is started, the cylinder moves and pushes the upper mold downward, pressing the metal plate downward. In cooperation with the lower mold, the bending process of the metal plate can be completed.

[0011] Preferably, the bending device is externally connected to a controller, which is used to control the start and stop of the first drive motor, the second drive motor, and the cylinder. By controlling the first drive motor, the second drive motor, and the cylinder through the external controller, the ease of use of the bending device is improved.

[0012] The advantages of this utility model are as follows: By cooperating with the first drive motor and the bidirectional screw, the positions of the connecting frame, baffle, and rubber pad are adjusted so that the baffle and rubber pad can be in contact with one side of the metal plate. Thus, during the bending process of the metal plate, the baffle and rubber pad physically limit and force the bending side of the metal plate, thereby fixing the reference edge of the plate and ensuring that the starting position of each bend is consistent. This avoids lateral displacement of the metal plate under force during bending and eliminates plate slippage during bending. At the same time, during multiple consecutive bends, the baffle and rubber pad can prevent positioning deviation caused by multiple feedings, thereby improving the accuracy of bending the metal plate.

[0013] This invention uses a second drive motor, a fan-shaped frame, and a push rod to continuously apply a pushing force to the arc-shaped plate and the force-receiving groove, thereby causing the connecting plate and the electromagnetic chuck to rotate continuously. This changes the bending edge of the metal plate. At the same time, through the cooperation of the electromagnetic chuck, the connecting rod, and the limiting component, the metal plate can move synchronously with one side during bending, thus ensuring the stability of the metal plate during bending and improving the convenience and quality of bending the metal plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 As shown, a metal sheet bending device includes: a processing table 1, a slide groove 2 on the processing table 1, a first drive motor 3 installed on one side of the processing table 1, a connecting shaft 4 fixedly connected to the output end of the first drive motor 3, a bidirectional screw 5 fixedly connected to one end of the connecting shaft 4, one end of the bidirectional screw 5 rotatably connected to the inside of the processing table 1, a connecting frame 6 threadedly connected to the bidirectional screw 5, an internal thread on the inside of the connecting frame 6, the connecting frame 6 slidably connected to the inside of the slide groove 2, a baffle 7 fixedly connected to one side of the connecting frame 6, and a rubber pad 8 fixedly connected to one side of the baffle 7.

[0023] In the processing of plate heat exchangers and coolers, the metal plates being processed need to be bent using a bending device. Therefore, a metal plate bending device is required. In actual use, after the metal plate to be bent is fixed using an electromagnetic chuck 18, the outer side of the metal plate to be bent is positioned above the lower mold 19. The first drive motor 3 is started via an external controller. The first drive motor 3 drives the connecting shaft 4 and the bidirectional screw 5 to rotate. Because the internal thread of the connecting frame 6 matches the thread on the bidirectional screw 5, the rotation of the bidirectional screw 5 can adjust the distance between the connecting frame 6 and the lower mold 19, allowing the rubber pad 8 to contact one side of the metal plate. When the metal sheet is pressed and bent by the upper mold 22 and the lower mold 19, the baffle 7 and the rubber pad 8 continuously block one side of the metal sheet. During the bending process, the baffle 7 and the rubber pad 8 physically limit and force the bending side of the metal sheet, thereby fixing the reference edge of the sheet and ensuring that the starting position of each bend is consistent. This avoids lateral displacement of the metal sheet under force during bending, thus eliminating sheet slippage during bending. At the same time, during multiple consecutive bends, the baffle 7 and the rubber pad 8 can prevent positioning deviations caused by multiple feedings, making the bending position of the metal sheet more accurate. In addition, the rubber pad 8 can reduce the impact force generated when the baffle 7 moves towards the metal sheet, thereby preventing dents from appearing on the bending side of the metal sheet.

[0024] Please see Figure 1-5 As shown, a second drive motor 9 is installed inside the processing table 1. A sector-shaped frame 10 is fixedly connected to the output end of the second drive motor 9. A push rod 11 is fixedly connected to the upper surface of one end of the sector-shaped frame 10. A connecting plate 12 is rotatably connected inside the processing table 1. A force-receiving groove 13 is formed on the lower surface of the connecting plate 12. The push rod 11 is drivenly connected to the force-receiving groove 13. An arc-shaped plate 14 is fixedly connected to the lower surface of the connecting plate 12. An anti-slip pad 15 is fixedly connected to one side of the arc-shaped plate 14. The arc-shaped end of the sector-shaped frame 10 is drivenly connected to the anti-slip pad 15. The upper surface of the connecting plate 12... A limiting rod 16 is fixedly connected and rotatably connected inside the processing table 1. A connecting rod 17 is provided inside the limiting rod 16. An electromagnetic chuck 18 is spherically hinged to one side of the connecting rod 17. A lower mold 19 is provided on the upper surface of the processing table 1. A support frame 20 is fixedly connected to the upper surface of the processing table 1. A cylinder 21 is installed on the upper surface of the support frame 20. An upper mold 22 is fixedly connected to the telescopic end of the cylinder 21. The bending device is externally connected to a controller, which is used to control the start and stop of the first drive motor 3, the second drive motor 9 and the cylinder 21.

[0025] The center of the metal sheet to be bent is attracted to the electromagnetic chuck 18. The electromagnetic chuck 18 is an electromagnetic chuck with an external power cord and switch. When the metal sheet is in contact with the electromagnetic chuck 18, the switch can be used to attract the metal sheet and fix its position. The weight of the metal sheet presses the connecting rod 17 into the limiting rod 16, so that the fixed metal sheet can be in contact with the lower mold 19. Then, the second drive motor 9 is started by the external controller, which drives the fan-shaped frame 10 to rotate, and at the same time drives the push rod 11 to rotate around the output shaft of the second drive motor 9. As the center rotates, the arc-shaped end of the sector frame 10 comes into contact with the anti-slip pad 15. Therefore, when the sector frame 10 rotates, it applies external force to the arc plate 14 and the anti-slip pad 15. Because the anti-slip pad 15 increases the friction between itself and the arc-shaped end of the sector frame 10, it enhances the transmission force on the sector frame 10. After the arc-shaped end of the sector frame 10 separates from one side of the arc plate 14, the push rod 11 reciprocates inside a set of force grooves 13. During this movement, the push rod 11 applies external force to both sides of the force grooves 13, thus cooperating with the external force on the arc plate 14 to continuously rotate the connecting plate 12. The connecting plate 12 is equipped with four sets of arc-shaped plates 14 and four sets of force-receiving grooves 13. Each rotation of the fan-shaped frame 10 causes the connecting plate 12 to rotate 45°. Since the electromagnetic chuck 18 is hinged to one side of the connecting rod 17, when the bending edge needs to be changed, the bending side of the metal plate located above the lower mold 19 can be adjusted by rotating the fan-shaped frame 10. After the metal plate is rotated, the suction force of the electromagnetic chuck 18 is turned off by a switch. The position of the metal plate is then manually adjusted again. The cylinder 21 is started by an external controller, and the cylinder 21 moves the upper mold... 22 is pushed downwards, pressing the metal plate downwards, and cooperating with the lower mold 19 to complete the bending process of the metal plate. During the bending process, the bent side of the metal plate is indented by force, which at the same time drives other parts of the metal plate to move upwards. By adjusting the tilt angle of the metal plate to the electromagnetic chuck 18, the connecting rod 17 is driven to move upwards along the inside of the limiting rod 16. This can continuously fix the position of the metal plate during the bending process. In cooperation with the baffle 7 and the rubber pad 8, it can prevent the metal plate from slipping during the bending process, thereby improving the bending quality of the metal plate.

[0026] Working principle: After the metal sheet to be bent is fixed using the electromagnetic chuck 18, the weight of the metal sheet presses the connecting rod 17 down into the limiting rod 16, allowing the fixed metal sheet to adhere to the lower mold 19. The first drive motor 3 is started via an external controller, driving the connecting shaft 4 and the bidirectional screw 5 to rotate. This adjusts the distance between the connecting frame 6 and the lower mold 19, continuously resisting one side of the metal sheet during bending under the pressure of the upper mold 22 and the lower mold 19, preventing lateral displacement and ensuring more precise bending. Then, the second drive motor 9 is started via the external controller, rotating the fan-shaped frame 10. Simultaneously, the push rod 11 rotates around the output shaft of the second drive motor 9. The arc-shaped end of the fan-shaped frame 10 adheres to the anti-slip pad 15, thus applying external force to the arc-shaped plate 14 and the anti-slip pad 15 as the fan-shaped frame 10 rotates. After the end separates from one side of the arc plate 14, the push rod 11 reciprocates inside a set of force grooves 13. During the movement, the push rod 11 applies external force to both sides of the force grooves 13, thus cooperating with the external force on the arc plate 14, which drives the connecting plate 12 to rotate continuously. When it is necessary to change the bending edge, the bending side of the metal plate located above the lower mold 19 can be adjusted by rotating the fan-shaped frame 10. Then, the cylinder 21 is started by the external controller. The cylinder 21 pushes the upper mold 22 downward, pressing the metal plate downward. Cooperating with the lower mold 19, the bending process of the metal plate can be completed. During the bending process, the bending side of the metal plate is concave due to force, which at the same time drives other parts of the metal plate to move upward. By adjusting the tilt angle of the metal plate to the electromagnetic chuck 18, the connecting rod 17 moves upward along the inside of the limit rod 16. During the bending process, the position of the metal plate can be continuously fixed, improving the bending quality of the metal plate.
