Flying shear
The flying shear is an important piece of equipment responsible for shearing in a 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 transverse 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 steel). They are also used to shred the edges of sheets cut by a rotary shear (i.e., a scrap shear).

Continuous flying shear
A shear that transversely shears workpieces during operation is called a flying shear. 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 cut-to-length shears, and is a product in modern rolling bar cutting, featuring low power consumption and low investment cost.
The flying shear is an important piece of equipment used in steel enterprises for shearing metal billets. 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 rockers, and workpiece, and then assembly and simulation, the shearing force acting on the workpiece during shearing and the movement trajectory of the two cutting edges can be obtained.
