[0020] Reference Figures 1 to 4 This utility model provides a technical solution: a guide device for a CNC bending machine, including a mounting base 12 slidably connected to one side of the top of the processing table 11, such as... Figure 1 As shown, to ensure the normal sliding of the mounting base 12, a first linear module 9 perpendicular to the position of the mounting base 12 is symmetrically connected to the top of the processing table 11. The bottom of the mounting base 12 is slidably connected to the first linear module 9 via a second sliding block 8. At the same time, a second linear module 10 is fastened to the top of the mounting base 12, and multiple supports 4 are connected to the top of the second linear module 10 via a first sliding block 5. In use, the supports 4 can slide on the top of the mounting base 12 under the drive of the second linear module 10. At the same time, the mounting base 12 slides under the drive of the first linear module 9, so that the supports 4 can be arbitrarily adjusted horizontally and vertically, thereby improving the practicality of the adjustment function.

[0021] like Figure 2 , 3 As shown in Figure 4, an opening 15 is made on one side of the support 4, and a first guide plate 6 is rotatably connected inside the opening 15 via a rotating shaft 17. A second guide plate 14 is vertically connected at the center of one side of the first guide plate 6, so that the second guide plate 14 and the first guide plate 6 form a T-shaped structure. The first guide plate 6 can limit and guide the end of the workpiece, thereby improving the bending quality of the workpiece. At the same time, the first guide plate 6 can be rotated to a horizontal position and form a T-shaped support structure with the second guide plate 14 on one side, which can also support the bottom of the workpiece, improving the practicality of the guiding function.

The electric push rod 13 slides and extends, pulling the U-shaped seat 18, which drives the rotating shaft 17 and the connecting seat 16 to rotate, thereby driving the first guide plate 6 and the second guide plate 14 to rotate and adjust within the opening 15. The structure is simple and convenient for users to adjust according to the needs of the processed parts.

[0023] In summary, when in use, the CNC bending machine guide device also includes a frame 1 fastened to the top of the processing table 11, an upper bending die 3 connected to the bottom of the frame 1 via a telescopic mechanism 2, a lower bending die 7 fastened to the processing table 11 located directly below the upper bending die 3, the top of the lower bending die 7 being on the same plane as the top of the support 4, and the top surface of the second guide plate 14 being on the same plane as the top surface of the support 4 when the second guide plate 14 is placed horizontally.
