Description

Technical Field

[0001] The utility model relates to the field of bending machines, in particular to a bending machine with an adjustment function. Background Art

[0002] A bending machine is a machine that can bend thin plates. During the bending process of metal plates, after the plates are clamped and fixed, the bending upper die descends to bend the plates. However, after the metal plates are bent, the lateral width will be relatively reduced, and the two sides of the metal plates are easy to break away from the fixed structure. For example, the Chinese utility model patent with the public document number: CN219924183U discloses a bending machine with an adjustment function. The utility model is provided with a clamping mechanism. The plates are placed on a limit plate, and the clamping plate moves to one side. The plates are clamped by the clamping plate to limit the position of the plates.

[0003] However, when the plate between the two clamping plates is bent, the plate is easy to separate from the clamping plates due to the reduction of the lateral distance. When some plates with severe rebound are bent, the bent plate is easy to pop up after the bending upper die is reset, posing a safety hazard to the workers. Therefore, the fixing structure of the plate must be able to adjust its position in time during the bending process, shrink and move inward, and maintain a movable connection with the plate to avoid the plate from popping out and injuring people. For this purpose, a bending machine with an adjustment function is proposed. Utility Model Content

The bending lower die 8 and the bending upper die 5 are installed through the fastening bolt 6, so that the bending upper die 5 and the bending lower die 8 are convenient for fixed connection and disassembly. The cylinder 3 pushes the bending upper die 5 downward, and after cooperating with the bending lower die 8, the metal sheet 9 is convenient for bending.

[0023] As Figure 1 、 Figure 2 and Figure 3As shown, the metal sheet 9 is movably installed on the workbench 1 through the position adjustment assembly 10. The position adjustment assembly 10 includes a chute 1001, a slider plate 1002, a pressure plate 1005, a connecting frame 1007, a movable tube 1010 and a movable rod 1012. The chute 1001 is opened on the workbench 1 and extends through the side of the support frame 2. The slider plate 1002 is movably installed in the chute 1001. The pressure plate 1005 is movably installed above the slider plate 1002. The metal sheet 9 is located between the slider plate 1002 and the pressure plate 1005. The connecting frame 1007 is fixedly connected to the side of the workbench 1. The movable tube 1010 is movably installed on the connecting frame 1007. The position adjustment assembly 10 further includes a fixed frame 1003, a fixing bolt 1004 and a rubber pad 1006. The fixed frame 1003 is fixedly connected to the slider plate 1002. The fixing bolt 1004 is movably installed on the fixed frame 1003, and the lower end of the fixing bolt 1004 is fixedly connected to the pressure plate 1005. The rubber pad 1006 is fixedly connected to the pressure plate 1005. The position adjustment assembly 10 further includes a storage tube 1008 and a positioning bolt 1009. The storage tube 1008 is fixedly connected to the fixed frame 1003. The movable tube 1010 is movably installed in the storage tube 1008. The positioning bolt 1009 is movably installed on the storage tube 1008. The position adjustment assembly 10 further includes a limiting head 1011. The limiting head 1011 is fixedly connected to both ends of the movable tube 1010. The spring 1014 is compressed between the baffle 1013 and the limiting head 1011 on one side, so that the spring 1014 can push the movable tube 1010 to the side, making the movable tube 1010 closely adhere to the slider plate 1002 and being connected as a whole. When moving the movable tube 1010, the slider plate 1002 can move synchronously in the chute 1001. The fixed frame 1003 is located inside the support frame 2. The support frame 2 and the fixed frame 1003 block each other to prevent the slider plate 1002 from sliding out of the chute 1001, making the slider plate 1002 easy to adjust according to the width of the metal sheet 9, so that the pressure plate 1005 can easily press both sides of the metal sheet 9.

The position adjustment assembly 10 further includes a baffle 1013 and a spring 1014. The baffle 1013 is fixedly connected to one end of the movable rod 1012. The spring 1014 is movably installed on the movable rod 1012 and is located between the baffle 1013 and the limiting head 1011. The movable rod 1012 is fixedly connected to the slider plate 1002. After the width of the metal sheet 9 decreases, when the slider plate 1002 is pulled by the metal sheet 9, it can continue to move laterally, and the movable rod 1012 moves synchronously in the movable tube 1010.

[0025] It should be noted that the present utility model is a bending machine with an adjustment function. The bending lower die 8 is fixedly connected to the bottom wall of the installation groove 7 through the fastening bolt 6, and the bending upper die 5 is fixedly connected to the installation plate 4 through the fastening bolt 6, so that the bending upper die 5 and the bending lower die 8 are convenient for fixed connection and disassembly. The metal sheet 9 is placed on the workbench 1, and the metal sheet 9 is located above the bending lower die 8. According to the width of the metal sheet 9, the movable tube 1010 in the receiving tube 1008 is pushed laterally. The limiting head 1011 at one end of the movable tube 1010 is squeezed and fitted with the slider plate 1002. The spring 1014 is located between the baffle 1013 and the limiting head 1011 at the other end. The spring 1014 pushes the movable tube 1010 laterally, so that the movable tube 1010 is closely attached to the slider plate 1002. When the movable tube 1010 is pushed, the slider plate 1002 moves synchronously. The slider plate 1002 slides in the chute 1001, and the height of the slider plate 1002 is flush with the height of the workbench 1. When the slider plate 1002 moves to a suitable position, the slider plate 1002 is located below the metal sheet 9. The fixing bolt 1004 is screwed downward, so that the pressing plate 1005 and the rubber pad 1006 move downward to fix the metal sheet 9. The positioning bolt 1009 is tightened, so that the movable tube 1010 is fixed and limited in the receiving tube 1008. The cylinder 3 is started, and the bending upper die 5 moves downward. The metal sheet 9 is bent downward, and a part of the metal sheet 9 is caught in the bending lower die 8, so that the width of the top view plane of the metal sheet 9 decreases. During the bending process, the slider plates 1002 on both sides of the metal sheet 9 move synchronously with the metal sheet 9. The movable rod 1012 moves laterally in the movable tube 1010, and the baffle 1013 moves laterally to further compress the spring 1014. Through the position adjustment assembly 10, during the bending process, the slider plate 1002 can adapt to the width change of the metal sheet 9 and move inward, so that the slider plate 1002, the pressing plate 1005 and the metal sheet 9 always maintain a fixed connection, avoiding the metal sheet 9 popping out and hurting people after the bending upper die 5 resets.
