Technical Field

[0001] This application relates to the field of sheet metal bending technology, and in particular to a bending device for sheet metal processing. Background Art

[0002] Sheet bending is a common metalworking technique used to bend sheet metal into desired shapes according to design requirements. This technique is widely used in the metalworking industry and involves various types of sheet metal, such as steel, aluminum, and stainless steel.

[0003] In the existing technology, when processing metal sheets, it is necessary to manually load the sheet to a designated position and bend one side, then change the direction and bend the other side, and then send it to a designated position again to repeat the operation.

[0004] Regarding the aforementioned technologies, the inventors believe that when using the bending device, it mainly relies on personnel to align the sheet metal with the bending mold, which requires a high level of skill from the workers to ensure the bending quality of the sheet metal. This results in a large labor input and a high level of operational difficulty.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0021] The following is combined with Figure 1 -4 provides further details regarding this application.

[0022] This application discloses a bending device for sheet metal processing. (Refer to...) Figure 1 - Figure 4 A bending device for sheet metal processing includes a bending table 1, a bending groove 2 on the upper part of the bending table 1, bending holes 3 for edge bending at both ends of the bending groove 2, and a bending mechanism 4 installed on the upper part of the bending table 1, capable of bending and transferring both ends of the sheet metal simultaneously. A loading port 5 communicating with the bending groove 2 is located on the upper part of the bending table 1. A loading platform 6 is installed at the bottom of the bending table 1 below the loading port 5. Limiting mechanisms 7 suitable for stacking and aligning different types of sheet metal are installed on the four sides of the loading platform 6. The boards are stacked on the loading platform 6. The four sides of the boards are limited by the limiting mechanism 7. Then, cylinder 8 extends to lift the top board to protrude from the upper end of the straightening bar 702. Then, cylinder 9 pushes the pusher plate 10 to push the board from one end of the bending groove 2 into the predetermined position of the bending groove 2, so that the two ends of the board to be bent are above the two bending holes 3. Then, the bending mechanism 4 bends the two ends of the board and transfers the bent board to the designated position. This cycle is repeated to reduce the difficulty of operation and improve bending efficiency.

[0023] Reference Figure 1 - Figure 2The bending mechanism 4 includes an L-shaped bracket rotatably mounted on one end of the upper part of the bending table 1. A motor 402 fixed to the bottom of the bending table 1 is connected to the bottom of the L-shaped bracket. A hydraulic rod 403 is mounted on the upper part of the L-shaped bracket. The output shaft of the hydraulic rod 403 is connected to a bending die 404. A positioning unit 405 for fixing and adsorbing metal sheets is movably mounted on the bottom of the bending die 404. The positioning unit 405 includes an electromagnet plate 4051, on which multiple guide rods 4052 are fixed. The guide rods 4052 are movably inserted into the bending die 404. Two springs 4053 are installed in the middle position of the bending die. The bottom end of the spring 4053 is connected to the electromagnet plate 4051. The bending die 404 is moved down by the hydraulic rod 403 and comes into contact with the two ends of the plate surface. At the same time, the electromagnet plate 4051 first contacts the upper surface of the plate, and the spring 4053 is compressed to generate pressure, so that the electromagnet plate 4051 is firmly fixed to the surface of the plate. Since the two ends of the plate are suspended, the two ends of the plate are bent under pressure. The bent metal plate (for metals that can be attracted by magnets) is attracted to the electromagnet plate 4051 and moves upward. Finally, the motor 402 rotates and moves the bent electromagnet plate 4051 to the designated position.

[0024] Reference Figure 1 - Figure 4 The limiting mechanism 7 includes four guide seats 701 fixed to the bottom of the bending table 1. A leveling bar 702 is movably mounted on each guide seat 701. An adjustment unit 703 is installed between the four leveling bars 702 on their closest sides. The adjustment unit 703 includes a second motor 7031 fixed to the bottom of the bending table 1. A turntable 7032 is connected to the output shaft of the second motor 7031. The turntable 7032 has four grooves, and a screw 7033 is rotatably mounted within each groove. An adjusting block 7034 is threaded onto the screw 7033. A connecting rod 7035 is hinged to the adjusting block 7034, and the other end of the connecting rod 7035 is hinged to the side of the straightening strip 702. By rotating the screw 7033, the adjusting block 7034 can drive the corresponding connecting rod 7035 to move independently, so that the corresponding straightening strip 702 can be adjusted according to the length and width of the board. When the turntable 7032 rotates, the four connecting rods 7035 can pull the four straightening strips 702 to move the same distance at the same time, ensuring that the four sides of the board can be straightened at the same time.

[0025] Reference Figure 2 - Figure 3A cylinder 8 is installed at the bottom of the loading platform 6. The cylinder 8 is fixed at the bottom of the bending platform 1, and a cylinder 9 is installed at the upper end of the bending platform 1. The output shaft of the cylinder 9 is connected to the pusher plate 10. By extending the cylinder 8, the stacked plates on the loading platform 6 are pushed up quantitatively. After rising, the cylinder 9 extends, driving the pusher plate 10 to push the uppermost plate towards the bending groove 2 to the designated position for bending.

[0026] The implementation principle of a bending device for sheet metal processing in this embodiment is as follows: Metal sheets are stacked on a loading platform. Then, motor 7031 drives turntable 7032 to rotate, causing connecting rod 7035 to pull aligning bars 702 closer to the sheet metal. This allows the four aligning bars 702 on the four sides of the sheet metal to conform to the sides of the sheet metal, thus aligning the sheet metal. Then, cylinder 8 rises, pushing the stacked sheet metal on the loading platform 6 upwards in a predetermined amount. After rising, cylinder 9 extends, driving pusher plate 10 to push the uppermost sheet metal towards the bending groove 2 to a designated position for bending. The bending is achieved by hydraulic... After the pressure rod 403 drives the bending die 404 to move down and abut against the two ends of the plate surface, the electromagnet plate 4051 first contacts the upper surface of the plate, and the spring 4053 is compressed to generate pressure, so that the electromagnet plate 4051 is firmly fixed to the surface of the plate. Since the two ends of the plate are suspended, the two ends of the plate are bent by pressure and form a bend. The bent metal plate (for metals that can be attracted by magnets) is attracted together with the electromagnet plate 4051 and moves upward. Finally, the motor 402 rotates and drives the bent electromagnet plate 4051 to move to the designated position.
