The driving member is then driven downward by the forming extrusion cylinder, and the roller connected to the driving member abuts against the upper end surface of the mounting column and pushes the mounting column downward. The mounting column drives the upper frame beam mold to move downward synchronously, so that the upper frame beam mold abuts against the frame beam and extrude the frame beam to form the frame, thereby bending the frame. After the frame is bent, the air holes are ventilated to allow air to circulate quickly around the frame, thereby achieving a rapid cooling effect on the frame. BRIEF DESCRIPTION OF THE DRAWINGS
