This invention relates to the field of hydraulic press technology and discloses a hydraulic press device for producing metal trash cans, including a main body with four positioning rods fixedly connected to the top of the main body. When the arc-shaped plate continues to press the top of the can and rotates, it provides guiding friction to the can body. At this time, the metal area at the top of the can body is bent and shaped as the arc-shaped plate rotates. When the can body pushes the arc-shaped plate upwards, the arc-shaped plate pre-presses the metal at the top of the can body. Then, when the arc-shaped plate drives the metal of the can body to rotate and curl the edge, it enhances the curling force while reducing the likelihood of cracks appearing in the metal body during the curling process. By assisting in increasing the curling strength of the metal body, the arc-shaped plate further improves the integrity of the curling angle and increases the curling efficiency.
