Classification of Shearing Machine

Good shear quality, small distortion deformation, but the shear force is large, high energy consumption. More mechanical drive. The shear upper and lower two knife edge parallel to each other, commonly used in steel rolling mills hot shear initial rolling billet and slab; according to its shear can be divided into up-cut and down-cut type.

In the aviation, shipping, automotive, light industry, metallurgy and construction industries, shearing machine is widely used to provide the required special machinery and complete sets of equipment.

Experts believe that shearing machine from different angles shearing machine has the following different kinds.

1. According to the different forms of the bed, can be divided into closed shearing machine and open shearing machine.

2. According to the different varieties of shear steel plate, can be divided into section shears, steel plate shears, billet shears and pipe cutting machine, etc..

3. According to the different temperature of the sheared plate material, can be divided into cold shears and hot shears, cold shears are mainly used to shear groups of small plate material, hot shears are mainly used to shear hot plate material.

4. According to the different ways of shearing, can be divided into longitudinal shears and horizontal shears, longitudinal shears are installed in the longitudinal shear line, the coil is unrolled, the plate is longitudinally sheared into narrow strips, and then through the winder will be narrow strips re-rolled into a strip coil, horizontal shears are used for horizontal shear plate, installed in the operation line for continuous rolling mill, can shear the head or tail of the plate, but also the plate can be cut to a fixed length.

5. According to the different driving methods, can be divided into mechanical, pneumatic, hydraulic shear, mechanical shear shear action relies on mechanical movement, usually applies to the thickness of less than 10mm plate, mechanical and pneumatic shear shear force is limited, if you improve the shear force, the structure to make a big change, not suitable for the thickness of more than 10mm plate, hydraulic shear by two hydraulic cylinders to drive. need to increase the shear force, only increase the shear cylinder thrust, the geometry of the size of the change is very small, and its system is simple, reliable performance, stable work.

6. According to the different ways of knife frame movement, can be divided into linear shear and swing shear, linear shear (gate shear) simple structure, easy to manufacture, rectangular blade cross-section, four sides can do knife edge, so more durable, swing shear knife frame in shear, around a fixed point for swing, mainly for shearing plate thickness greater than 4 mm, plate width of less than 4000 mm plate material Shearing machine. Shearing machine is an important auxiliary equipment in the steel rolling machinery, the main role is to carry out metal processing.

Shearing machine is a blade relative to another blade for reciprocating linear motion, and the use of up and down scissors to cut the plate material machine. The specific shearing action is with the help of the movement of the upper blade and the fixed lower blade, using a reasonable gap between the blades, to apply shear force to the sheet metal, so that the sheet material according to the actual required size fracture separation.
