The machine is used for shearing cross moving parts, which began in the late 19th century, after a century of development, in the production of the use of flying shear type teaching. At present, the widely used flying shears are: disc flying shears, rotary flying shears, crank connecting rod flying shears.

　The eccentric fly shears, swing fly shears, crank connecting rod fly shears, etc. According to the current use of fly shears and the development requirements of wire production, fly shears have the following two development trends:

The above is a brief analysis of the types, functions and characteristics of flying shears in wire production. Through this design, I have a deeper understanding of the flying shear machine and the whole wire production, and I have a more detailed understanding of the working principle and application of the flying shear of crank connecting rod, thus laying a solid foundation for my future work.
