A one-time half-flip U-shaped edge and half-rolling device comprises a rolling mechanism mounted on the left side of an upper template, a U-shaped punch mounted on the right side, and an upper drive mechanism mounted on the front and rear sides of the middle portion of the upper template. A U-shaped die is mounted on the lower template in a position corresponding to the U-shaped punch. A slider seat and a rolling slider are mounted in positions corresponding to the upper drive mechanism. A lifting block is installed in the center of the rolling slider. During operation, a sheet is placed on the lifting block. The upper template descends, and the lower drive block moves the rolling mechanism to the right until the rolling mandrel and the U-shaped punch engage. The upper template then descends again, punching the sheet into a U shape. The upper template continues downward, and the rolling slider rounds half of the sheet. During reset, a return spring pulls the rolling mandrel to the left, causing the product to rise under the action of the lifting spring, allowing the workpiece to be removed. This device is rationally designed, utilizing a sliding rolling mandrel to achieve both rolling and convenient material removal, while simultaneously performing both functions in one positioning operation, thereby improving product quality.
