Sliding block guide track structure of four-column hydraulic press

Abstract

The invention relates to a sliding block guide track structure of a four-column hydraulic press. The sliding block guide track structure is characterized in that the four columns of the hydraulic press are rectangular, guide tracks are arranged on the four side surfaces of each column, rectangular guide chambers matched with the column guide tracks are arranged at the four corners of the sliding block of a hydraulic press, and a guide plate and an adjusting device matched with the guide tracks are correspondingly installed on the internal side of each guide chamber. The thrust surface of a sliding block guide mechanism is increased, the problem that the clearance between guide tracks becomes smaller because of unbalance loading is solved, the strength and the unbalanced loading resistanceof the sliding block guide mechanism are greatly improved and the service life of the sliding block guide mechanism is improved; and the installation is easy and the adjustment of the clearance between guide tracks is convenient.

Description

technical field [0001] The invention relates to a slider guide rail structure of a four-column hydraulic press. Background technique [0002] At present, the guide mechanism of most hydraulic machines adopts outer X guide rails (that is, four 45° inclined guide rails are fixed on the outside of the fuselage pillars, and the top view is "X" type) or four-corner and eight-sided guide rails (that is, four pillars, each pillar has two rail surface). When this kind of guide rail is pressing the workpiece, the guide rail gap becomes smaller (due to the particularity of the large partial load of the heavy-duty forging hydraulic press), and the specific pressure of the guide rail increases sharply, causing scratches on the guide rail, thereby affecting the service life of the slider guide mechanism. The quality of the pressed workpiece is also adversely affected. Therefore, it is necessary to frequently overhaul the hydraulic press and replace the guide rails in time, but the repl...

AI Technical Summary

Problems solved by technology

When this kind of guide rail is pressing the workpiece, the guide rail gap becomes smaller (due to the particularity of the large partial load of the heavy-duty forging hydraulic press), and the specific pressure of the guide rail increases sharply, causing scratches on the guide rail, thereby affecting the service life of the slider guide mechanism. The quality of the pressed workpiece also has a detrimental effect

Therefore, it is necessary to frequently overhaul the hydraulic press and replace the guide rails in time, but the replacement of the guide rails is cumbersome, and the entire maintenance and replacement process is time-consuming and laborious, which affects work efficiency
