HARSLE guillotine machine cutter supplier will introduce you what is shearing machine. A shearing machine is a machine that uses one blade for reciprocating linear motion shear plate with another blade. It's a used blade and a fixed blade, using a reasonable blade, to apply shear force to the metal sheets of various thicknesses, and to make the board break apart at the size of the required size. Shearing machine is a kind of forging machinery, the main function is metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, ship, automobile, electric power, electric appliance, decoration and other industries to provide the special machinery and complete equipment.
Special plate shears
Cooperate with other equipment for special purpose:
1. Cold bending molding line shears: for example, the special shears that are used in the production lines such as the cold bending line of the automobile longitudinal beam, the side baffle plate production line, the color steel plate molding line, etc.;
2. Shearing machine for steel structure production line: it is mainly used for cutting process of Angle steel and h-beam automatic production line;
3. Plate shearing machine: it is used for high speed shearing machine designed to meet the requirement of fast cutting of the production line, and the thick plate line is mostly hydraulic high-speed shearing machine, and the thin plate line is equipped with pneumatic shearing machine. High-speed online with flying shears, continuous production, high efficiency.
Diagonal cutting machine
Shearing machine of upper and lower blade into a point of view, generally on the blade is tilted, the slope Angle is commonly 1 ° to 6 °. The shear of the diagonal shear is smaller than the flat blade, so the power of the motor and the weight of the whole machine is reduced, and the most practical application, the shearing machine is producing these kind of shears.
Flat blade shears
The shear quality is good, the distortion is small, but the shear force is large and the energy consumption is large. More mechanical transmission. The two blades of the shearing machine are parallel to each other, and are often used in the hot shearing of the rolling mill and the slab. According to its shear mode can be divided into upper cut and lower cut type.
Multi-purpose shears
1. Combined punching and shearing machine: the shear of the plate can be finished, and the profile can be cut.
2. Plate bending and shearing machine: the process of cutting and bending can be accomplished on the same machine.

The specific method to adjust the blade clearance of the plate shear is to adjust the blade clearance of the plate shear with a single stroke, At that time, it is necessary to loosen the locking screw temporarily. When the blade of the upper plate shear descends to the lower dead center, quickly turn the ball valve to close the oil circuit, make the upper tool holder of the plate shear stop at the lower dead center, and then lock the screw.
Then continue to open and close the ball valve slightly to make the upper knife rest of the plate shear rise section by section in the whole stroke. At this time, measure the evenness of the blade edge clearance of the plate shear section by section, and check whether the blade edge clearance of the plate shear is adjusted properly,
Adjust and turn on the plate shearing machine for several cycles of shearing, and try to cut plates of different thicknesses from thin to thick. After ensuring that there are no abnormal conditions, turn the handle to the required scale value.
The ball valve is used to measure the uniformity of the upper and lower edge clearance of the blade of the plate shear. Whether the edge clearance of the blade of the plate shear is appropriate or not is an important factor affecting the shear quality and prolonging the service life of the blade.
