Brief introduction of plate shearsPlate shears is a machine that uses one blade to cut the plate in a reciprocating linear motion relative to the other blade. By means of moving upper blade and fixed lower blade, reasonable blade clearance is adopted to apply shear force to metal plates of various thickness, so that the plates are broken and separated according to the required size. Plate shears belong to a kind of forging machinery, the main role is the metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipping, automobile, electric power, electrical appliances, decoration and other industries to provide special machinery and complete sets of equipment. Main categories Special plate shears Cooperate with other equipment to complete special purpose 1. Cold forming line shears: for example, special shears for automobile longitudinal beam cold forming line, car side baffle production line, color steel plate forming line, etc; 2. Steel structure production line shears: mainly used for angle steel, H-beam automatic production line to complete the cutting process; 3. Plate opening and leveling line shears: for plate uncoiling and leveling line, high-speed shears are designed to meet the requirements of high-speed cutting in production line. Hydraulic high-speed shears are mostly used in thick plate line, and pneumatic shears are mostly used in thin plate line; High speed line equipped with flying shear, continuous production, high efficiency. Inclined blade shears The upper and lower blades of the shearing machine form an angle. Generally, the upper blade is inclined, and the inclination angle is generally 1 ° to 6 °. The shearing force of the inclined blade shears is smaller than that of the flat blade shears, so the motor power and the weight of the whole machine are greatly reduced. The shears are mostly used in practice, and most of the shears are produced by the shears manufacturers Flat blade shears The shear quality is good and the distortion is small, but the shear force is large and the energy consumption is large. There are more mechanical transmission. The upper and lower blades of the shears are parallel to each other, and are often used in hot shearing of blooms and slabs in rolling mills; According to its cutting mode, it can be divided into up cutting type and down cutting type. Multi purpose plate shears 1. Combined punching and shearing machine: it can complete the cutting of plate and profile, mostly used in blanking process; 2. Sheet metal bending and shearing machine: that is, two processes of shearing and bending can be completed on the same machine. |
