In the production process of Coil Cut To Length Line, shearing is a crucial part. Different cutting methods can have a significant impact on productivity and product quality. This article will introduce three common cutting methods: flying shear, fixed shear and rotary shear, to help customer better understand the characteristics and advantages of these cutting methods.
Flying shear is a high-speed shearing method, suitable for the coil thickness is thin. Through the high-speed rotation of the blade, the coil will be quickly cut into the desired length. Flying shear has the characteristics of fast cutting speed and high efficiency, which is suitable for the scenario of high productivity requirements. However, because high-speed cutting generates a large cutting force and heat, the requirements for the equipment are higher, and the sharpness of the cutting blade and the stability of the equipment need to be ensured.
Fixed shear is a common shearing method for coils with large thicknesses. By positioning the cutter, the coil is cut precisely to the required length. Fixed shear is characterised by high cutting precision and flat cuts, and is suitable for scenarios with high product quality requirements. However, due to the slow speed of the fixed shear, the productivity is relatively low. In addition, fixed shear requires large cutting force, which requires high stability of the equipment and durability of the tool.
The rotary shear is a shearing method that combines a flying shear and a position shear. The web is cut to the desired length by a combination of rotating and positioning knives. The rotary shear combines the high speed and efficiency of the flying shear with the precision and quality of the cut of the fixed shear. This type of cutting is suitable for medium coil thicknesses and can improve product quality while ensuring productivity.
The choice of shearing method for coil fixed shear line needs to be determined according to the specific production needs and product requirements. Flying shear is suitable for scenes with high requirements for production efficiency, fixed shear is suitable for scenes with high requirements for product quality, and rotary shear is a combination of the advantages of both. Through a reasonable choice of shearing methods, you can improve production efficiency and product quality, and further promote the development of the coil sizing shear line industry.
