Description

Technical Field

[0001] This utility model relates to the field of metallurgical rolling mill equipment technology, and in particular to a reciprocating flying shear machine. Background Technology

[0002] In production lines of the steel and non-ferrous metals rolling industries, such as bar rolling lines and section rolling lines, continuously rolled pieces need to be cut to specified lengths for subsequent packaging, transportation, and further processing. A reciprocating flying shear is used for cutting these pieces.

[0003] The shearing action of a reciprocating flying shear is achieved by the reciprocating linear motion of the blade or shear edge. It performs periodic reciprocating motion in the direction of the rolled workpiece's movement according to a specific motion law. When the rolled workpiece reaches the appropriate shearing position, the shear edge quickly closes during its movement to cut the workpiece. After cutting, the shear edge quickly separates and returns to its initial position to prepare for the next shearing action.

[0004] When faced with a large workload, reciprocating flying shears may move at high speeds during operation, or the workpieces being cut may be hard, which may cause the flying shears to loosen, leading to accidents. Furthermore, if the flying shears are damaged, they are not easy to replace. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a reciprocating motion flying shear machine, which aims to improve the problems of flying shears becoming loose, causing accidents, and flying shears being difficult to replace if damaged.

[0006] To achieve the above objectives, the present invention provides the following technical solution:
