& nbsp; The flying shear fixed length cutting production line, also known as the flying shear, is a cutting machine for rolling pieces in horizontal cutting operation. It is a processing equipment that can quickly cut iron plates, steel pipes, and paper rolls. It is a fixed length cutting machine for metallurgical steel rolling industry, high-speed wire and threaded steel, and is a product in modern rolling bar cutting. It has the characteristics of low power consumption and low investment cost.  & nbsp; Many friends may have embossing when using stop cutting for thin plates made of materials such as copper, aluminum, and silicon steel, and the cutting speed is difficult to meet the requirement of a constant speed of 60m/min. After years of research and development, Jinan Zeye has produced flying shear equipment and provided better solutions to some of the problems faced by customers and friends.  & nbsp; Firstly, we need to understand the cutting principle of the flying shear fixed length cutting production line. As follows:& nbsp;  & nbsp; The sheet metal in the flying shear fixed length cutting production line is quickly cut by a feeding machine through its cutting blades. A synchronous speed and a synchronous length are calculated by the arithmetic unit of the line cutting length and the average rate of sheet metal supply. A synchronous speed reference pulse corresponding to a frequency. The synchronous length is provided to the first digital controller to control the feeder, and the second digital controller is used to control the rotary shear.  & nbsp; When the steel coil is supplied at a synchronous speed, the first digital controller controls the speed of the steel plate conveyed by the feeder and adjusts the length of the steel coil to be cut in online cutting in a certain way.  & nbsp; When the steel coil rotates at synchronous speed, the second digital controller controls the rotation speed of the rotating cutting edge and adjusts the length of the 360 degree rotation trajectory circumference of each cutting edge in online cutting in a certain way.
