Description

Technical Field

[0001] The utility model relates to the technical field of billet hydraulic shears, in particular to a large-angle billet hydraulic shear. Background Technique

[0002] The working principle of a hydraulic shear mainly depends on the force generated by liquid pressure. It mainly consists of a lower knife base, an upper knife base, an oil cylinder, a hydraulic station, etc. When the machine runs, the hydraulic station provides pressure oil, causing the piston of the oil cylinder to move downward, pushing the lower knife base upward until it contacts the upper knife base. After the upper and lower knife bases clamp the metal material, the oil cylinder moves upward, causing the lower knife base to quickly descend to complete metal cutting.

[0003] During the shearing process of the existing hydraulic shear for billets, due to the weight of the billet itself, when the billet is not easy to handle, most of the shearing operations are carried out in the horizontal state of the billet. It cannot be adjusted at a large angle for shearing as needed, and the shearing angle is limited, which is not suitable for the processing of billets with rich daily alternations. Therefore, improvements are needed. Content of the Utility Model
