Fly Shearing of Modern Small Rolling Mills
Fly Shearing technology is a new type of shearing technology developed in recent years. It is suitable for shearing plates and strips of rolling mills. It has the advantages of short shear length, fast speed, low noise and high production efficiency. As an important part of modern small rolling mills, fly shearing is an important part of the automation level of small rolling mills.
Fly Shears is composed of two parts: a fly shearing machine and ancillary devices. The ancillaries are mainly hydraulic components, electrical instrumentation, movements,fly shearing machine, etc. The hydraulic system is mainly responsible for the operation of the fly shearing machine, the transmission of power and the determination of the degree of shearing. The electrical components mainly include electrical switches, buttons, overload relays, contactors, and others. Movements are generally composed of roll forming, roll adjustment and roll pressing.
The fly shearing machine is mainly composed of fly shearing knife and fly knife base. The fly knife base is an important component of the fly shearing machine. It consists of main shaft, fly knife shearing runout adjustment components, shear clearance adjustment components and so on. The fly knife blade serves as the shearing blade of the fly shearing machine. Generally, different knife materials are used in different types of materials, such as alloy steel blades, carbon steel blades, and composite blades.
The principle of fly shearing is to use the movement of the fly knife base and the fly knife to realize the formation, shear and break of the plate. The general fly shearing machine is mainly composed of two parts, a fly knife base and a fly knife blade. When the fly knife blade runs on the fly knife base, the fly knife base rotates at high speed and its cutting edge is offset from the cutting edge of the fly knife blade. In this way, the plate is sheared into the required length. It can be said that the fly shearing machine works according to the principle of shear cutting.
Fly Shear technology can realize film galvanizing, color coating, winding strip galvanizing and other processes. It is mainly used in small and medium-sized rolling mills, such as cold-rolled strip steel rolling mills, hot-rolled strip steel rolling mills, color coating line manufacturing, etc. In the production process, the parameters of the blade gap can be adjusted according to the size of the material. This can avoid the generation of burrs, reduce the production cost of the rolling mill and improve the product quality of the rolled product.
In summary, fly shearing is an important part of modern small rolling mills. It has the advantages of short shear length, fast speed, low noise and high production efficiency. It is mainly used for shearing plates and strips of rolling mills. It can be applied in the rolling mills of cold rolled steel strip, hot rolled steel strip and color coated line manufacturing. Through the use of fly shear technology, the rolling mill can not only reduce the production cost, but also improve the product quality.
