Flying shear machine
The flying shear machine is an important equipment responsible for cutting in the flying shear line. The flying shear machine is divided into double crank rotary and single crank parallel rotary.
A flying shear is a type of shearing machine that performs transverse shearing on moving rolled pieces. The flying shear machine is mainly used for cutting medium and small steel billets, thin slabs, small steel sections (bars), as well as hot and cold rolled strip steel (including coated steel). It is also used to cut the edges of the plate cut by a disc shear machine (i.e. edge crusher).
Non-stop cross cutting machine
The shear machine for rolling pieces in transverse shear operation is called a flying shear, which is a processing equipment that can quickly cut iron plates, steel pipes, and paper coils. It is a fixed length cutting machine for the metallurgical steel rolling industry, high-speed wire and threaded steel. It is a product in modern rolling bar cutting, with the characteristics of low power consumption and low investment cost.
Flying shear is an important equipment used by steel companies to shear metal billets, and its performance directly affects the production efficiency of rolling production lines. There are many structural forms of flying shear mechanisms. In this chapter, a four link structure is adopted. Through simple three-dimensional modeling of its frame, upper and lower cranks, upper and lower connecting rods, upper and lower rocker rods, and workpiece, assembly and simulation can be carried out to obtain the shear force received by the workpiece during the cutting process and the motion trajectory of the two shear blades.
