AI Technical Summary
When forging complex-shaped metals, traditional hydraulic presses are prone to errors in the flatness of the mold, resulting in low product quality and low work efficiency. They cannot meet the requirements of high-speed forming and are prone to vibration and noise during the stamping process.
The CNC servo hydraulic punch press, through the cooperation of the hydraulic system and the oil pump motor, achieves automated control and smooth hydraulic cylinder movement. Combined with the limit fixing seat and the directional limit plate, it ensures the levelness of the mold and the verticality of the hydraulic cylinder, controls the pressing speed and the smooth release of hydraulic energy, and eliminates vibration and noise.
It improves hydraulic efficiency, ensures product flatness, extends mold life, reduces labor intensity, and achieves the effects of rapid descent, slow pressurization, pressure holding, and rapid return. It also solves the problems of off-center loading error and vibration in traditional hydraulic presses.
