[0022] See Figures 1-2 A bending unit for a V-shaped bending machine includes: a frame 1, which serves to mount various mechanisms; a support platform 2, mounted on the frame 1, which supports aluminum alloy sheets; a clamping mechanism, located at the upper end of the frame 1, which cooperates with the support platform 2 to clamp the aluminum alloy sheets; and positioning posts on both sides of the support platform 2 to position the sheets. After the sheets are positioned, they are clamped and fixed by the clamping mechanism, and then formed by a mold mechanism, resulting in accurate positioning and high processing precision.

[0023] The lower mold mechanism is slidably mounted on the support platform 2; the upper mold mechanism is slidably mounted on the upper end of the frame 1.

The upper template is slidably mounted on the frame 1, and the upper hydraulic cylinder 8 is fixedly mounted on the frame 1. The piston rod of the upper hydraulic cylinder 8 is connected to the upper template. The upper hydraulic cylinder 8 drives the upper template to move downward, and the lower hydraulic cylinder 6 drives the lower template to move upward. The upper and lower templates cooperate to form a V-groove.

[0026] The upper pressure plate 3 is equipped with an upper guide rail 9, and the upper template is slidably installed on the upper guide rail 9, which plays a guiding role during the sliding process, making it more stable and reliable.
