Plate shears is a machine that cuts a plate with a reciprocating straight motion from one blade to another. It is through the moving upper blade and fixed lower blade, using a reasonable blade gap, the shear force is applied to the metal sheet of various thicknesses, so that the sheet is broken and separated according to the required size. Plate shears belong to one of the forging machinery, the main role is the metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment.
Working principle
After shearing, the shears should be able to ensure the straightness and parallelism of the shear surface of the shears, and minimize the distortion of the plates to obtain high-quality workpieces. The upper blade of the shearing machine is fixed on the tool holder, and the lower blade is fixed on the work table. A supporting ball is installed on the work table so that the plate will not be scratched when sliding on it. The rear baffle is used for plate positioning, and the position is adjusted by the motor. The press cylinder is used to press down the plate to prevent it from moving during shearing. Guardrails are safety devices to prevent workplace accidents from occurring. The return trip generally relies on nitrogen, which is fast and has little impact. The use of the shearing machine: according to the thickness of the material to be cut, adjust the gap of the blade; Adjust the mold or fixture according to the width of the material to be cut; Before the operation of the shearing machine, make 1-3 empty strokes, and the shearing work can be implemented after normal.
In use, if the machine is found to run abnormally, the power should be cut off immediately to stop the check.When adjusting the machine tool, the power supply must be cut off, and the safety of the hand should be paid attention to when moving the workpiece.
Each part of the shearing machine should be constantly lubricated, and each shift should be filled with lubricating oil by the operator once, and the rolling bearing part should be filled with lubricating oil by the mechanic once every six months.
