JH25 Double Crank Gap Frame Power Press
Benefits & Features
Wide Table Press Optimized for Progressive Die and Multi-Station Die StampingThe Wide Table Press is specifically designed for progressive die and multi-station die stamping, featuring a enhanced bolster and slide plate dimensions compared to single-crank presses, making it ideal for large-size tooling applications. Its C-type open-back body design facilitates side coil sheet feeding or front-to-back sheet feeding, ensuring seamless material handling. With two tonnage center points, the press delivers greater power at the ram sides, enhancing stamping efficiency and precision. The bolster surface undergoes grinding to achieve superior flatness, while customizable scrap dropping holes in the bolster allow for tailored waste management solutions. Additionally, the bolster and slide plate sizes are fully customizable, and standard T-slots are integrated into both components for easy tooling setup and flexibility. |
Reverse-Rotated Double Crankshaft Design for Gap Frame Press Machines
The double crankshaft mechanism, crafted from 42CrMo alloy steel through precision forging and rolling treatment, ensures a ultra-smooth surface finish for enhanced durability and reduced friction. Its reverse-rotated design effectively eliminates lateral forces, promoting stable operation and minimizing deflection. The copper-impregnated connecting rod bush and high-quality front/rear shaft bushes, coupled with grease lubrication, guarantee low-maintenance performance and extended component lifespan. Additionally, the ball screw undergoes nitrogen treatment to achieve superior hardness, while precisely timed twin transmission gears ensure synchronized motion and optimal power transfer. This integrated engineering solution delivers exceptional reliability, efficiency, and precision for demanding industrial applications.
| High-Torque Wet-Type Pneumatic Clutch with Solenoid Valve Control The self-produced high-performance wet-type combined clutch and brake system delivers exceptional reliability and simplified maintenance, ensuring consistent operation in demanding industrial environments. Its Toyooki/Taco/Ross brand dual-safety solenoid valve provides precise control over clutch and brake functions, guaranteeing synchronized and fail-safe performance. The integrated air pressure meter, coupled with a safety air pressure switch, monitors and regulates operational pressure to guarantee safe and efficient operation of the crank punching press. Additionally, the standard-equipped safety clutch cover further enhances operator protection and compliance with safety standards, making this system a robust and secure solution for high-precision applications. |
Smart HMI System for Automated Press Machines featuring Simplified WorkflowThe system features an LCD touchscreen with comprehensive setting and monitoring capabilities. Operators can configure lubrication frequency and duration, cam angles, and cam controller types directly through the intuitive interface. Real-time status indicators include a crankshaft angle light, lubrication alarms, and overload warnings, ensuring clear visibility of press operation. The control panel integrates an emergency stop button, mode selection switches, and an overload reset switch for immediate access. Additionally, a counter with preset function enables efficient production planning and scheduling. |
Efificient Centralized Control System for Power Press Automation
The system supports both mechanical and electric cam controllers, with selectable options via the touchscreen interface. Auxiliary user cam controllers are also available for enhanced flexibility. Equipped with high-quality encoders and renowned brand PLCs (including Omron, Panasonic, and Schneider), ensuring reliable and precise control performance.
