Flying shear
The flying shear is an important device 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 shear that performs lateral shearing on moving workpieces. Flying shears are mainly used to shear medium and small steel billets, thin slabs, small sections (bars), and hot-rolled and cold-rolled strip steel (including coated steel). They are also used to shred the edges cut off by rotary shears (i.e., edge shredders).

Continuous Flying Shear
A flying shear is a machine that shears workpieces during lateral shearing operation. It is a processing equipment that can quickly cut iron plates, steel pipes, and paper rolls. It is used in the metallurgical rolling industry, high-speed wire rod and rebar sizing shears, and is a product in modern rolled bar cutting, characterized by low power consumption and low investment cost.
Flying shears are important equipment used in steel enterprises to shear metal billets. Their performance directly affects the production efficiency of rolling production lines. There are many structural forms of flying shear mechanisms. This chapter uses a four-bar linkage structure. By performing simple 3D modeling of its frame, upper and lower cranks, upper and lower connecting rods, upper and lower rocker arms, and workpiece, and then performing assembly and simulation, the shearing force exerted on the workpiece during shearing and the motion trajectories of the two cutting edges can be obtained.
