Cut to Length Machine BOYA

BOYA shear is often used in steel rolling production line. In the continuous rolling billet workshop or small section workshop, it is placed at the end of the rolling line to cut the rolled pieces into fixed length or only the head or end of cutting part. In cold and hot rolling workshops there are various types of flying shears used in the horizontal shear unit, heavy shear unit, galvanizing unit and tin plating unit, which cut the strip into a fixed size or cut into a specified weight coil.

BOYA cross-cutting shear is advanced, high precision, greatly promote customer production to high-speed and continuous development.

What's cut to length machine?

Steel cut to length machine is a Horizontal shear machine used for unwinding, leveling, sizing, cutting into the required length of flat sheet and stacking.

Suitable for processing cold rolled and hot rolled carbon steel, silicon steel, tinplate, stainless steel and coated metal materials. According to the application, the equipment can be classified as silicon steel transverse shear line (transformer core transverse shear line), stainless steel transverse shear line, copper foil aluminum foil transverse shear line, cardboard transverse shear line and so on. According to its electronic control type can be classfied into CNC transverse shear line, pneumatic transverse shear line and so on.

The Impact of Temperature on the Blade of Cut To Length Machine during High Speed Cut

Based on our pursuit of production efficiency, we need to increase the shear speed and reduce cutting time. However, while increasing the shear speed, the working temperature of the blade rises, the force is large, causing the blade to accelerate wear. On the other hand, the blade is affected by the heat expansion, and further affects shear quality.

In the initial stage of the shear, the overall temperature of the cutter is raised. As shear is stable, the blade is in contact with the strip, the high-temperature area is increased, and the remainder temperature is slightly reduced; after shear enters the steady-state, the blade edge temperature Although it increases, the increase is gradually reduced until it is stable in a constant temperature.
