The Difference Between Four Column Hydraulic Press and Frame Hydraulic Press

no-load state no guiding vs load state of no guiding

As shown in the structural comparison of Figure 1 and Figure 2, when there is no guide structure, once the pressing slider is stressed, most working conditions will encounter eccentric loading. When eccentric loading occurs, it is easy to cause the product accuracy to be substandard, the yield rate to be low, and the cylinder to be easily damaged. Damage, so the slider needs to be guided.Through years of development of hydraulic presses, the hydraulic press has designed a four-column guide structure and a frame guide structure.

four column guide structure vs frame guide structure

With four-column or frame-type structural guides, eccentric loads are significantly improved. So what is the difference between a four column hydraulic press and a frame hydraulic press? Here is an analysis of why frame-based guidance is better. The guide structure of the four-column hydraulic press uses round guide sleeves to guide the four columns. When unbalanced load occurs, the guide sleeve relies on the accuracy of the guide sleeve to closely match the guide. When there is a certain gap, the guide sleeve is mainly stressed up and down. angle two points.
