[0021] As Figure 1 and Figure 2 shown, the present utility model provides a technical solution for an adjustable flat steel bending device, including an equipment base 1, on which a flat steel chute 2 is fixedly installed. A fixing nut 3 is provided at the end of the flat steel chute 2. A hollow positioning shaft 4 is provided on the equipment base 1. A fixed roller 5 is provided on the hollow positioning shaft 4.

After the flat steel is bent, the unloading mechanism 7 can be used to quickly push out the flat steel in the flat steel chute 2.

[0022] As Figure 2 and Figure 3 shown, the bending mechanism 6 includes a movable shaft 609 movably installed inside the hollow positioning shaft 4. A rotating arm 602 is fixedly installed at the upper end of the movable shaft 609. A moving roller 601 is movably installed at the end of the rotating arm 602. A driven gear 608 is fixedly installed at the lower end of the movable shaft 609. A reduction gear 607 is provided on one side of the driven gear 608.

[0023] Specifically, the servo motor 603 can drive the driving gear 606 to rotate. After the driving gear 606 rotates, it will drive the reduction gear 607 to rotate. After the reduction gear 607 rotates, it will drive the rotating arm 602 on the driven gear 608 to rotate, causing the moving roller 601 to rotate around the fixed roller 5, bending the flat steel, and the bending angle of the flat steel can be adjusted by controlling the rotation angle of the servo motor 603.

[0024] As Figure 2 and Figure 4 shown, the unloading mechanism 7 includes a driving lead screw 701 movably installed in the equipment base 1. A lead screw nut 703 is provided on the driving lead screw 701, and a pushing block 702 is fixedly installed on the lead screw nut 703.

[0026] Working principle: When in use, first place the flat steel in the flat steel chute 2, and then push the flat steel forward so that the flat steel is clamped between the fixed roller 5 and the moving roller 601. After the flat steel is clamped between the fixed roller 5 and the moving roller 601, the first clutch 605 can be controlled to engage. After the first clutch 605 engages, the servo motor 603 can be started. After the servo motor 603 is started, it will drive the driving gear 606 to rotate. After the driving gear 606 rotates, it will drive the reduction gear 607 to rotate. After the reduction gear 607 rotates, it will drive the rotating arm 602 on the driven gear 608 to rotate. After the rotating arm 602 rotates, it will drive the moving roller 601 to rotate around the fixed roller 5, thereby bending the flat steel. And the bending angle of the flat steel can be adjusted by controlling the rotation angle of the servo motor 603. After the flat steel is bent, the fixing nut 3 can be loosened. After the fixing nut 3 is loosened, the second clutch 707 can be controlled to engage. After the second clutch 707 engages, the servo motor 603 can be started. After the servo motor 603 is started, it will drive the drive shaft 604 to rotate. After the drive shaft 604 rotates, it will drive the second drive shaft 706 to rotate.

After the drive screw 701 rotates, it will drive the screw nut 703 to move forward. After the screw nut 703 moves forward, it will drive the pushing block 702 to move forward, thereby pushing out the flat steel in the flat steel chute 2 and automatically completing the unloading instead of manual labor.
