Flying shear
The flying shear is an important piece of equipment responsible for shearing in the flying shear line. Flying shears are classified into double-crank rotary and single-crank rotary types.
A flying shear is a type of shearing machine that performs lateral shearing on moving workpieces. Flying shears are mainly used to shear medium and small steel billets, thin slabs, small-sized steel (bars), and hot-rolled and cold-rolled strip steel (including coated). They are also used to shred the edges cut off by a rotary shear (i.e., a scrap shear).

Continuous flying shear
A shear that shears workpieces during lateral shearing is called a flying shear. It is a processing equipment capable of quickly cutting iron plates, steel pipes, and paper rolls. It is used in the metallurgical rolling industry and for high-speed wire rod and rebar length-cutting machines. As a product in modern rolling bar cutting, it features low power consumption and low investment costs.
The flying shear is an important piece of equipment used in steel enterprises for shearing metal blanks. Its performance directly affects the production efficiency of the rolling production line. There are many structural forms of flying shear mechanisms. This chapter adopts a four-bar linkage structure. Through simple 3D modeling of its frame, upper and lower cranks, upper and lower connecting rods, upper and lower rocker arms, and workpiece, and then assembly and simulation, the shearing force acting on the workpiece during shearing and the motion trajectory of the two cutting blades can be obtained.
