[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] Please see Figures 1-5 As shown, the purpose of this embodiment is to provide a flexible bending device for metal sheets, including a bending machine 1. The bending machine 1 includes a housing 2 and a compaction structure 3. A groove 4 is provided at one end of the housing 2. The compaction structure 3 is fixedly installed on the top of the housing 2. The compaction structure 3 includes a pressure block 5 and a spring-loaded device 6. The pressure block 5 is slidably installed at the bottom of the compaction structure 3. The spring-loaded device 6 is T-shaped and is fixedly installed at both ends of the pressure block 5. The spring-loaded device 6 is used to assist the pressure block 5 in moving up and down. The device also includes a bending structure 7, which is slidably installed in the groove 4. The bending structure 7 includes a base 8 and a lifting device 9. Two lead screws 15 are rotatably installed on the lifting device 9, and the other end of the lead screws 15 is threadedly connected to the base 8. The bending structure 7 is used to bend metal sheets.

[0021] The housing 2 is L-shaped, and a feeding platform 10 is fixedly installed on the upper surface of the horizontal end of the housing 2. The metal sheet to be processed is placed on the feeding platform 10, and the feeding device on the bending machine 1 will move the metal sheet to the appropriate position.

[0022] The bottom of the compaction structure 3 is provided with a sliding groove 11. A cylinder 20 is fixedly installed on the inner wall of the top of the sliding groove 11. The output end of the cylinder 20 is fixedly connected to the top of the pressure block 5. The pressure block 5 is slidably installed in the sliding groove 11 through the cylinder 20. The cylinder 20 presses down and rises the pressure block 5. The sliding groove 11 can prevent the pressure block 5 from shifting.

[0023] The rebound device 6 includes a housing 12 and a T-shaped limiting block 13. A limiting groove 14 is provided at the bottom of the housing 12, and the inner wall of the top of the limiting groove 14 is elastically connected to the top of the limiting block 13 by a spring. The limiting block 13 is slidably installed in the limiting groove 14 by the spring. When the rebound device 6 touches the surface of the feeding table 10, it continues to press down, and the limiting block 13 moves up and moves into the limiting groove 14, so that the spring in the limiting groove 14 is compressed, so that the pressing block 5 is buffered during the downward pressing process.

[0024] An arc-shaped tubular mold 16 is rotatably mounted on the top of the base 8 via a rotating shaft, and a motor A17 is fixedly mounted on one end of the rotating shaft. A screw hole is opened at the bottom of the base 8, and the screw hole is threadedly connected to the lead screw 15. When the motor A17 is started, it drives the mold 16 to rotate. When the motor B21 is started, the lead screw 15 rotates, which allows the base 8 to move up and down. The movement of the base 8 drives the mold 16 to move.

[0025] The lifting device 9 has a positioning groove 18, in which two sprockets 19 are rotatably installed. The two sprockets 19 are connected by a chain drive. A motor B21 is fixedly installed on one side of one of the sprockets 19. The two sprockets 19 are respectively fixedly connected to one end of two lead screws 15. When the motor B21 is started, it drives the sprocket 19 to rotate. The two sprockets 19 rotate synchronously through the chain drive. The rotation of the sprocket 19 drives the lead screw 15 fixedly connected to it to rotate.

[0026] In practical use, the metal sheet to be processed is placed on the feeding table 10. The feeding device of the bending machine 1 moves the metal sheet to the edge of the feeding table 10 near the edge of the compaction structure 3. The cylinder 20 is activated, and the pressing block 5 moves downward from the slide groove 11 under the push of the cylinder 20. The spring-loaded devices 6 installed at both ends of the pressing block 5 first touch the surface of the feeding table 10. As the pressing block 5 continues to move downward, the limiting block 13 moves into the limiting groove 14, compressing the spring in the limiting groove 14, thus buffering the pressing block 5 during its downward pressing process. When the pressing block 5 presses the metal sheet, the motor B21 starts. The motor A17 drives the sprocket 19 connected to it to rotate. The two sprockets 19 rotate synchronously through chain transmission. The rotation of the sprocket 19 drives the lead screw 15 to rotate. The rotation of the lead screw 15 allows the base 8 to move up and down. The movement of the base 8 drives the mold 16 to move and bend the metal sheet. When the metal sheet needs to be bent at a certain angle, the motor A17 starts and drives the mold 16 to rotate and bend the metal sheet at a certain angle. When the metal sheet needs to be bent multiple times, the cylinder 20 pulls the pressure block 5 upward and quickly returns it to a certain height through the springback device 6, moving the metal sheet to repeat the above bending process.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. 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 utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
