The left and right cylinders are fixed on the columns. The slide is connected to the piston of the cylinder and moves up and down along the guide rail fixed on the column. The lower die is fixed on the workbench, and the upper die is installed at the lower end of the slide. The hydraulic system provides power and the electrical system gives instructions. Under the action of the cylinder, the slide drives the upper die downward and closes the lower die to achieve the bending of the sheet.
[0003] The rear stopper of the bending machine is an important working mechanism for bending positioning of the bending machine. Its main function is to control the feeding length of the plate to be processed and ensure that the plate is bent at the predetermined position. In order to facilitate the precise positioning of the bending part, the stopper beam needs to be adjusted; however, the stopper beam of some existing bending machines cannot be fine-tuned after installation.
[0004] In view of the above problems, we propose a straightness adjustment device for the material blocking beam of a bending machine. Utility Model Content

[0036] In the device, since the moving block 5 and the threaded rod 3 are threadedly connected, Figure 2 As shown, the threads on the threaded rod 3 start from the middle part of the threaded rod 3, and the directions of the threads on both sides are opposite. Therefore, when the threaded rod 3 is driven to rotate by turning the rotating handle 4, the moving directions of the moving blocks 5 at the side ends of the threaded rod 3 will also be opposite; when the rotating handle 4 is turned clockwise, the two moving blocks 5 will move toward the middle of the threaded rod 3, that is, the two moving blocks 5 will move closer; when the rotating handle 4 is turned counterclockwise, the two moving blocks 5 will move toward the two ends of the threaded rod 3, that is, the two moving blocks 5 will move away from each other.
[0037] The moving block 5 is connected to the cross beam 6 by a support rod 7, and the two ends of the support rod 7 are connected to the moving block 5 and the cross beam 6 by a connecting assembly 8. Therefore, when the rotating handle 4 is turned clockwise, the two moving blocks 5 are brought together, and the position of the cross beam 6 will rise, and it will rise at a straight line and uniform speed; when the rotating handle 4 is turned counterclockwise, the two moving blocks 5 are separated, and the position of the cross beam 6 will fall, and it will fall at a straight line and uniform speed. Therefore, the height of the cross beam 6 can be fine-tuned by turning the rotating handle 4.
[0038] As a preferred embodiment of the present invention, Figure 4 As shown, the connecting assembly 8 includes two mounting blocks 9 and a connecting shaft 10. The connecting shaft 10 is a cylindrical structure and is fixedly installed between the two mounting blocks 9. The connecting assembly 8 is configured to achieve a rotational connection between the support rod 7 and the moving block 5 and the crossbeam 6.

The two second sliders 16 are mounted on the upper ends of the slide rails 13, and the second sliders 16 are slidably connected to the slide rails 13. The material blocking plate 17 is fixedly mounted on the upper ends of the two second sliders 16. The driving motor 19 is fixedly mounted on the side ends of the material blocking plate 17 through the connecting plate 18. The gear 20 is fixedly mounted on the output shaft of the driving motor 19, and the gear 20 is meshed and connected with the rack 14. The working principle of the material blocking component 15 is specifically as follows: first start the driving motor 19, and after the driving motor 19 is started, it will drive the gear 20 to rotate. Since the gear 20 is meshed and connected with the rack 14, and the rack 14 is fixed to the upper end of the crossbeam 6, the rotation of the gear 20 will drive the material blocking plate 17 and the second slider 16 to move on the slide rail 13, thereby adjusting the position of the material blocking component 15.
[0042] As a preferred embodiment of the present invention, Figure 5 As shown, both ends of the upper end of the cross beam 6 are fixedly installed with limiting columns 21; the setting of the limiting columns 21 is used to limit the material blocking assembly 15 to prevent the material blocking assembly 15 from falling off the slide rail 13 during the movement on the slide rail 13.
[0043] As a preferred embodiment of the present invention, Figure 5 As shown, a scale bar 22 is fixedly mounted on one side end of the cross beam 6 close to the rack 14 ; the scale bar 22 is provided to facilitate direct observation of the width between the two stopper assemblies 15 .
