YLC21 series CNC hydraulic press

YLC21 series CNC hydraulic press

Performance characteristics: The hydraulic press is smooth and vibration-free when stamping, easy to operate, and not easy to cause industrial accidents. The power system is equipped with an overflow protection device to effectively protect the body parts and molds, which greatly improves the safety performance of the equipment. It has the incomparable advantages of pure mechanical punches, and is recognized by the industry as the direction of the future sheet metal flexible processing system. The punching force of mechanical punching presses is from small to large, and there is no sufficient punching force at any position of the full stroke. Hydraulic punching presses completely overcome this shortcoming and can achieve "constant impulse". For the punch of hydraulic press, it has the function of soft punching, which not only improves labor production
