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.
Resistance to oil discharge from the lower chamber of the master cylinder. Pipes and valves will reduce the oil return rate of hydraulic oil due to the regulation of flow rate, which will cause the hydraulic oil to cause descending resistance to the slider. decline.
The white weight of the slider is not enough, and the white weight of the slider is one of the driving forces for the rapid lowering of the slider. Because the cylinder piston rod, upper die, etc. are all located on the slider, in order to easily explain the problem, it is regarded as a component of the slider, that is, the self-weight of the slider includes the weight of the above and the parts mounted on the slider.
The blocking force created by friction. Because the friction between the slider and the guide rail has little effect on the slider speed, it can sometimes be ignored.
