The lower pressing mold and the pushing direction of the first hydraulic cylinder 42 form an angle of 40 degrees.

[0021] In the present invention, the positioning platform 3 is the prior art.

[0022] With the above structure, the robot places the beam product that needs to be flanging on the positioning table 3, and the positioning table 3 automatically positions and clamps the beam. The flanging mold 44 is pushed to the predetermined position by the first hydraulic cylinder 42, and the pressing mold 46 is pushed downward by the first hydraulic cylinder 42. The second hydraulic cylinder 43 drives the flanging mold 44, so that the pressing mold 46 and the lower mold 461 are pressed downward.

An oil-free wear-resistant slide plate is used, and the lower mold 46 is in the middle of the slide plate. When the second hydraulic cylinder 43 drives the flanging mold 44 to push the pressing mold 46 to the right, the third hydraulic cylinder 45 also pushes the pressing mold 46 downward, so that the pressing mold 46 is pressed downward along the slide plates on both sides, and the front and rear movement of the hydraulic cylinder is converted into a 40° movement of the flanging lower mold 461, so that the limited space is reasonably used, the product is flanging and folded into place, the flanging mold 44 is separated from the beam product, and the robot grabs the beam product again and moves it to the next station, forming a fully automatic flanging process.
