The working principle of hydraulic shearing machine

Hydraulic shearing machine

Hydraulic shearing machine is a machine that uses one blade to reciprocate linear motion relative to the other blade to cut the plate. With the help of the moving upper blade and the fixed lower blade, a reasonable blade gap is used to apply shearing force to the metal plates of various thicknesses, so that the plates are broken and separated according to the required size. Shearing machine is a kind of forging machinery, and its main function is the metal processing industry.

Shearing machine

Shearing machine is a kind of shearing equipment widely used in machining, which can cut steel plate materials of various thicknesses. Commonly used shears can be divided into: pendulum shears and gate shears according to the movement mode of the upper knife. Products are widely used in aviation, light industry, metallurgy, chemical industry, construction, ships, automobiles, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment.


After shearing, the hydraulic shearing machine should be able to ensure the straightness and parallelism of the shearing surface of the sheared plate, and minimize the distortion of the plate 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 worktable. A material support ball is installed on the worktable, so that the sheet will not be scratched when sliding on it. The back gauge is used for sheet positioning, and the position is adjusted by the motor. The pressing cylinder is used to press the sheet to prevent the sheet from moving during shearing. Guardrails are safety devices to prevent workplace accidents. The return journey generally relies on nitrogen, which is fast and has a small impact.
