[0038] In this embodiment, in order to achieve the effect of switching different bending shapes, the bending adjustment assembly 4 is designed. There are two inner convex layers 4-1 arranged inside the equipment base 1. An activity cavity 4-2 is opened between the inner convex layers 4-1 and the equipment base 1. A slidable moving seat 4-3 is slidably connected inside the activity cavity 4-2. A conversion frame 4-4 is rotatably connected between the moving seats 4-3. A plurality of bending frames 4-5 for cooperating with the bending press frame 3 to perform bending are installed on the conversion frame 4-4. A switching motor 4-7 is installed on one side of the moving seat 4-3 for controlling the rotation of the conversion frame 4-4 to switch different bending frames 4-5. A driving screw 4-6 is installed in the moving cavity for controlling the outward movement of the moving seat 4-3. When switching is required, it moves outward to avoid the bending frame 4-5 colliding with the equipment base 1 during switching. A fixed block 4-8 is arranged at one end of the rotating frame. A telescopic cylinder 4-9 is arranged on the outer surface of the equipment base 1. The output end of the telescopic cylinder 4-9 is connected with a locking block 4-10. After the conversion frame 4-4 rotates, it can be supported on the bottom of the fixed block 4-8 by the locking block 4-10 to fix the conversion frame 4-4.

[0039] Furthermore, the positioning assembly 5 includes a pair of transverse cylinders 5-1, the transverse cylinders 5-1 are installed on both sides inside the top frame 2, the output end of the transverse cylinder 5-1 is connected with a vertical cylinder 5-2, the output end of the vertical cylinder 5-2 faces downward, the output end of the vertical cylinder 5-2 is connected with a positioning frame 5-3, the positioning frame 5-3 is located inside the surface of the equipment base 1, and the surface of the positioning frame 5-3 is a hollow structure.

[0043] Furthermore, the height of the upper end face of the bending frame 4-5 is slightly lower than the height of the surface of the equipment base 1.

[0044] In this embodiment, due to the slightly lower height, when the workpiece is placed on the surface of the equipment base, it can slide inward and fit against the positioning frame 5-3, which is convenient for positioning and does not affect the bending and forming.

[0045] Furthermore, the overall shape of the movable cavity 4-2 is a cross-shaped structure, and the two side surfaces of the movable cavity 4-2 are open structures.

[0046] In this embodiment, due to the cross-shaped structure, the moving seat 4-3 slides stably inside and can be connected to the conversion frame 4-4 and the driving screw 4-6 at the same time.

[0047] Furthermore, the fixing block 4-8 is a polygonal structure, and the number of sides on the surface of the fixing block 4-8 matches the number of bending frames 4-5.

[0048] In this embodiment, through the polygonal structure during switching, it can be fixed according to the corresponding surface, making the conversion frame 4-4 unable to rotate.

[0049] Furthermore, the outer shapes of the top end faces of several bending frames 4-5 are all different structures.

[0050] In this embodiment, various different structures are used to adjust the bending according to each switch.

[0051] When in use, according to the required bending, first start the driving screw 4-6 to control the moving seat 4-3 to move outwards, start the switch and control the rotating conversion frame 4-4 to rotate the corresponding turning frame vertically upwards. After the adjustment is completed, start the telescopic cylinder 4-9 to control the locking block 4-10 to support at the bottom of the fixed block 4-8 to keep it fixed. According to the thickness of the workpiece, start the horizontal cylinder 5-1 and the vertical cylinder 5-2 to adjust the depth and height of the positioning frame 5-3. Place the workpiece on the surface of the equipment seat 1 and push it inwards to abut against the surface of the positioning frame 5-3, and then start the hydraulic cylinder 6-1 to control the bending frame 3 to press down for bending.

[0052] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
