[0002] A plate shears (English name: plate shears; guillotine shear) is a machine that uses one blade to reciprocate linearly relative to another blade to shear plates. It relies on the moving upper blade and the fixed lower blade, with a reasonable blade gap, to apply a shearing force to metal plates of various thicknesses, causing the plates to break and separate according to the required dimensions. The plate shears belong to one type of forging machinery, and its main function is in the metal processing industry. The products are widely applicable to industries such as aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobiles, electricity, electrical appliances, and decoration to provide the required special machinery and complete sets of equipment.

[0003] In the existing metal plate shears, the upper cutting knife is driven by swing wheels on both sides to cut metals. However, the balance mechanism is not provided for the swing wheels on both sides. When a motor on one side fails, the swing wheels on both sides cannot be balanced, affecting the balance of the cutting knife, and further resulting in unevenness of the plate cut, which affects the cutting quality.
