Abstract
The utility model relates to a full-automatic U-tube cold-roll forming device. The full-automatic U-tube cold-roll forming device comprises a rack, and clamping components fixed on the rack, namely, a clamp component, a dabber and a rotational molding component. The clamp component and the rotational molding component are respectively arranged on two sides of the dabber. The clamp component can also slide towards the direction away from the dabber. The rotational molding component can rotate on the horizontal plane at 180 degrees with the dabber as the center of the circle. A thin-wall copper tube is clamped and positioned by the clamp component and then the rotational molding component rotates around the center of the circle at 180 degrees, and thus the thin-wall copper tube is fabricated into a U-shaped tube. In the blending process of the cooper tube, the thin-wall copper tube is always clamped, and after the brake is formed, the component has the advantages of being free of rift and corrugation, and smooth and attractive in appearance. Meanwhile, the full-automatic U-tube cold-roll forming device further has the advantages of saving manual labor in U-shaped tube processing and saving the cost.
