shearing machine manufacturer introduced: the cutting machine is a machine that its one blade moving in a straight line relative to another blade and uses the scissors to cut the plate. The specific shearing action is to use the upper blade of the movement and the fixed lower blade, and use reasonable blade clearance to apply shear force to metal sheet, so that the sheet material can be broken apart according to the actual size. The shearing machine is an important auxiliary equipment in the steel rolling machine, and its main function is to process metal. In aviation, ship, automobile, light industry, metallurgy and construction industries, shearing machines are widely applied to provide special machinery and complete equipment needed.
The shearing machine manufacturers believe that the shearing machine has the following different kinds from different angles: The shearing machine manufacturers think that according to the form of bed, the shearing machine can be divided into closed shears and open shears; According to the variety of shear steel plate, it can be divided into section steel shearing machine, steel plate shearing machine, billet shearing machine and pipe cutting machine, etc. It can be divided into cold shears and hot shears according to the different temperature of the sheared sheet. The cold shears are mainly used to shear the small plate materials, and the hot shears are mainly used to shear hot plate. According to the different methods of shear, it can be divided into longitudinal shearing machine and transverse shearing machine, slitting machine is installed on the slitting line, roll material out, sheet metal is longitudinal sheared into narrow band, then the narrow band is rewound to a coil by a reeling machine, transverse shearing machine is used for lateral shear sheet, installed in the continuous rolling mill production line, can cut the head or the tail of the sheet, also can make the sheet metal sheared for the specified length;
According to the different driving mode, it can be divided into mechanical, pneumatic and hydraulic shearing machine, the shear action of mechanical shears depends on the mechanical movement, which is usually suitable for plates with thickness less than 10mm, the shear force of mechanical and pneumatic shearing machine is limited, if the shear force is increased, the structure should be changed greatly, and they are not suitable for the plate with thickness more than 10mm. The hydraulic shearing machine is driven by two hydraulic cylinders, when the shear force is necessarily increased, it is just necessary to increase the thrust of the shearing oil cylinder, and the size of the geometric structure is changed very little, and the system is simple, performance is reliable and work is stable. The manufacturers of the shearing machine also think that the shearing machine can be divided into straight line and swing shearing machine according to the different movement way of the knife frame. The straight-line shearing machine (brake type shearing machine) has simple structure, convenient manufacturing, rectangular blade section, and its four edges can be used for cutting edge, so it is more durable, the knife frame of the pendulum shears is used to swing around a fixed point when cutting, it is mainly suitable for shearing the shearing machine with the sheet material which of plate thickness greater than 4 mm and plate width less than 4000 mm.
