| An electric-hydraulic press brake is a mechanical device used for metal sheet processing, primarily for bending or folding metal sheets. It utilizes an electro-hydraulic hybrid drive system, combining hydraulic and electrical control systems to achieve high-precision bending operations. An electric-hydraulic press brake typically consists of the following main components: Frame: The frame of the electric-hydraulic press brake is usually made of a sturdy welded steel plate, providing sufficient strength and stability to withstand the pressure and vibrations during the machining process. Worktable: The worktable is a platform used for placing and securing the metal sheets. It is typically made of a robust steel plate and equipped with fixtures and clamping systems to ensure the stable and accurate positioning of the metal sheets during the bending process. Ram: The ram is the moving component of the electric-hydraulic press brake, which performs vertical up and down movements driven by hydraulic cylinders or servo motors. The ram is usually fitted with bending tools or dies to apply pressure on the metal sheets and achieve the bending operation. Hydraulic system: The hydraulic system is a critical part of the electric-hydraulic press brake, providing power and controlling the vertical movement of the ram. The hydraulic system consists of hydraulic pumps, hydraulic cylinders, hydraulic valves, and hydraulic oil tanks. The hydraulic pump pushes hydraulic oil into the hydraulic cylinder to drive the movement of the ram. Electrical control system: The electric-hydraulic press brake is also equipped with an electrical control system, which monitors and controls the machine's operation. The electrical control system typically includes buttons, switches, programmable controllers, and displays, allowing for programming and setting of bending angles, pressure, and speed parameters to achieve automated bending operations. The electric-hydraulic press brake offers easy operation, high precision, efficiency, and wide applicability to different types of metal sheets. It is widely used in various industries such as manufacturing, aerospace, automotive, and construction, within the metal sheet processing sector. |
