It is one of the key ways to reduce the working time of the hydraulic press and improve the working efficiency and level of the hydraulic press products by increasing the quick-fall rate of the slider to shorten the operation cycle of the hydraulic press machine. During the actual production of the project or during the transformation of the device, it is often faced with the disadvantage that the rapid drop rate of the slider is small, so the specified standard cannot be met. At present, many experts, scholars and front-line engineers have begun to conduct precise and rigorous discussions on the rapid drop rate of the sliding block of the lifting hydraulic press machine. The descending effect and return speed, some experts and scholars have ensured the rapid descending rate of the hydraulic press machine by analyzing the influencing factors of the failure of the hydraulic press of the imported short-cycle veneer device, and using the method of expanding the flow rate of the hydraulic check valve.
