[0008] Furthermore, the top of the reduction motor is connected to a connecting rod via a connecting sleeve, the top of the connecting rod is provided with a transmission wheel via a flat key fixing sleeve, and the transmission wheel is located at the top of the base.

[0009] Furthermore, auxiliary rods are sleeved through both sides of the top of the gantry, and the bottom ends of the auxiliary rods are connected to the top of the fixing frame through threaded grooves.

[0010] Furthermore, a compression spring is sleeved on the outer side of the vertical pole, and the compression spring is located on the top of the gantry.

[0011] Furthermore, an auxiliary wheel is installed at one end of the top of the base through a bearing, and a cutting groove is opened at one end of the top of the base located on one side of the gantry; the opening of the cutting groove prevents the high-speed rotating cutting blade from cutting the knife base.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The cylinder pushes the driving wheel to extrude the aluminum profile to make it bend. The reduction motor moves the driving wheel to rotate, thereby pushing the aluminum profile to move. When the aluminum profile moves, it is bent to form a circle. After the aluminum profile is formed, the vertical rod can push the driving motor and the high-speed rotating cutting blade downward to cut the bent and formed aluminum profile and make it fall off the unformed aluminum profile.
