The invention discloses a
metal fine-rolling method and a
metal fine-rolling device, and control over micro part rolling is achieved. The
metal fine-rolling method comprises the following steps that a rolled metal passes an unreeling mechanism and then enters a lubricating mechanism, and the lubricated rolled metal enters a precise rolling
machine for rolling; an
automatic control system starts a
servo motor by means of preset parameters, the power is input into a
reducer through a coupler, the power is divided into two ways through the
reducer to drive a lower roll and an upper roll to rotate through the universal coupler; a
servo electric cylinder is stated while the
servo motor is started, pressing is conducted according to a preset pressing quantity, and rolling on the rolled metal is started; a micro heater is stated while rolling is conducted, the rolled metal being subject to rolling is driven by a supporting roll to enter scrubbing-
drying equipment, then the rolled metal enters into a
leveling mechanism, and finally, crimping and winding are conducted on the rolled metal through a constant-tension controller of a winding mechanism. According to the metal fine-rolling method and the metal fine-rolling device, a panel and the other sections can be rolled to 0.008 mm, thickness-varying rolling can be achieved, the materials and time are saved, and the cost is reduced.
