Slitting and slitting machine is a kind of mechanical equipment used to cut metal sheets, coils and other materials into strips longitudinally, which is widely used in the industries of iron and steel, construction, automobile, electrical appliances and so on. In this article, we will introduce two aspects of the working principle and classification of the longitudinal shear slitting machine.

　　First, the working principle of longitudinal shear slitting machine

　　The working principle of the slitting machine is through the upper and lower two scissors on the metal plate, coil and other materials for longitudinal cutting, to achieve the plate, coil and other materials cut into strips. Among them, the upper scissors are fixed cutting edge and the lower scissors are movable cutting edge. Through the movement of the upper and lower scissors, metal sheets, coils and other materials are cut into strips of specified width.

　　The working principle of the slitting machine has the following main steps:

　　Material loading: Place the metal sheet, coil and other materials to be cut on the feeding device of the longitudinal shear slitting machine for positioning and clamping.

　　Feeding: start the feeding device to feed the metal sheet, coil and other materials into the cutting area of the longitudinal shear slitting machine.

　　Cutting: Start the upper and lower scissors to cut the metal sheet, coil and other materials in longitudinal direction.

　　Slitting: The cut metal sheet, coil and other materials are divided into strips of specified width and sent out through the feeding device.

　　Second, the classification of longitudinal shear slitting machine

　　Slitting machine can be divided into the following categories according to the different cutting methods:

　　1. Roll cutting slitting machine

　　Rolling shear slitting machine adopts roller feeding device to feed metal sheets, coils and other materials into the cutting area of the hob set, through the rotation of the hob for longitudinal cutting. Roller shear slitting machine is suitable for cutting thin metal sheets, coils and other materials.

　　2.Shear type slitting machine

　　Shear type slitting machine adopts upper and lower scissors for longitudinal cutting, the cutting tool is fixed cutting edge and movable cutting edge. Shear slitting machine is suitable for cutting thicker, hard metal sheets, coils and other materials, with high cutting efficiency, high cutting accuracy, good quality cutting surface and other advantages.

　　3.Laser Slitting Machine

　　Laser slitting machine adopts laser beam for longitudinal cutting, and the laser beam can cut metal plates, coils and other materials with high precision and high speed. The laser slitting machine is suitable for cutting metal strips with high precision and high quality.

　　4.Pendulum type slitting machine

　　Pendulum slitting machine adopts pendulum feeding device and shear cutting method to feed metal sheets, coils and other materials into the cutting area and cut them longitudinally with upper and lower scissors. Pendulum type slitting machine is suitable for cutting longer and wider metal sheets, coils and other materials.

　　Overall, the slitting and slitting machine is a very important mechanical equipment, widely used in steel, construction, automobile, electrical appliances and other industries. Through different cutting methods and technical means, the longitudinal shear slitting machine can meet the cutting needs of different industries and materials, with high efficiency, high precision, high quality and other advantages.
