Principle of single-wheel and double-wheel punch

Single-wheel punch refers to a punch with one-stage transmission structure. The principle is that the motor drives the flywheel, the clutch on the flywheel is combined to drive the crankshaft to rotate, and the crankshaft drives the crank slider to reciprocate up and down to realize punching. Double-wheel punch press means that the punch press has two or more stages of transmission structure, in which the motor drives the flywheel with a clutch (the clutch of pneumatic friction clutch punch press is on the flywheel) and the pinion coaxial with the flywheel drives the big gear (the clutch of rigid clutch is on the big gear). If it is a three-stage transmission, there may be a gear pair, a crankshaft and a large gear coaxially driving the slider to move up and down for stamping. The tonnage of single-wheel drive punch will not be very large, medium-sized punch adopts two-stage drive, and large punch may adopt three-stage or above transmission structure.
