Sheet metal shearing machine is a machine that uses one blade to reciprocate linear motion relative to the other blade to cut the plate. By means of a moving upper blade and a fixed lower blade, a reasonable blade gap is used to apply shearing force to metal sheets of various thicknesses, so that the sheets can be broken and separated according to the required size. The plate shearing machine is a kind of forging machinery, and its main function is the metal processing industry. The sheet shearing machines are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide special machinery and complete sets of equipment required.
After shearing, the shearing machine should be able to ensure the straightness and parallelism of the shear surface of the sheared sheet, and minimize the distortion of the sheet to obtain high-quality workpieces. The upper blade of the shearing machine is fixed on the knife holder, and the lower blade is fixed on the workbench. A material holding ball is installed on the workbench to prevent the sheet from being scratched when sliding on it. The back gauge is used for positioning the plate, and the position is adjusted by the motor. The pressing cylinder is used to compress the sheet to prevent the sheet from moving during shearing. The guardrail is a safety device to prevent accidents at work. The return journey generally relies on nitrogen, which is fast and has little impact.
Special shearing machine is used with other equipment to complete special purposes:
Such as special shearing machine configured on production lines, automobile longitudinal beam cold bending line, car side baffle production line, color steel plate forming line, etc.
Mostly used for angle steel and H-beam automatic production lines to complete the shearing process
Used on the plate uncoiling and leveling line, a high-speed shearing machine designed to meet the high-speed cutting requirements of the production line. The thick plate line is mostly hydraulic high-speed shearing machine, and the thin plate line is more equipped with pneumatic shearing machine. The high-speed line is equipped with flying shears and has continuous production and high efficiency.
The upper and lower blades of the shearing machine form an angle. Generally, the blades are inclined, and the inclination angle is generally 1° to 6°. The shearing force of the oblique 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, and the actual application is the most. Shearing machine manufacturers often produce this type of shears.
The flat blade shearing machine's quality is good, the distortion is small, but the shearing force is large, and the energy consumption is large. More mechanical transmission. The upper and lower blades of the shearing machine are parallel to each other, and are often used for hot shearing of blooms and slabs in rolling mills. According to the shearing method, it can be divided into up-cutting and down-cutting.
It can complete the cutting of the plate and the profile, which is mostly used in the blanking process.
That is, two processes of shearing and bending can be completed on the same machine.
The mechanical shearing machine adopts resistance key form clutch structure and open gear transmission, and adopts more advanced electrical operation. The all-steel welding structure is simple, easy to operate, beautiful in appearance, and low energy consumption.
The hydraulic shearing machine has beautiful appearance, excellent performance and stable quality. It uses a moving upper blade and a fixed lower blade, and uses a reasonable blade gap to apply shearing force to metal sheets of various thicknesses. The required size breaks apart.
The swing beam shearing machine combines performance and simplicity. The robust steel welded machine frame ensure high reliability and excellent cutting quality. These shearing machines allow precise cuts with reducing deformations to a minimum. The low cutting angle on this type of shears allows to limit sheet metal twist and bow.
Hydraulic guillotine shear is suitable for making heavy duty cutting off for more production requisite. Guillotine shearing machine is suitable for working over sheet metals and plate metals. The machine is featured with excellent functional aspects that make it a top preference in many metal working industries. The guillotine shearing machine structure is made of higher grade material that allows for lesser maintenance as well as easy operation.
Ordinary shears are mechanical operations that require manual operations.
CNC shears generally use general-purpose or special-purpose computers to achieve digital program control, which usually controls mechanical quantities such as position, angle, speed, and switching quantities related to the direction of mechanical energy flow. The production of CNC shears relies on the appearance of data carriers and binary data operations.
