Abstract

The invention discloses a hydraulic servo rolling mill for producing battery pole sheets, which comprises a pedestal, a frame arranged on the pedestal, a lower mill roller and an upper mill roller both arranged inside the frame, a computer-controlled press-down servo hydraulic cylinder connected on a bearing seat for holding the rollers, and computer-controlled roller-bending hydraulic cylinders respectively arranged outside the lower bearing seat of the lower mill roller and the upper bearing seat of the upper mill roller to adjust the bearing clearance between the lower and the upper mill rollers. The invention has three control modes of constant-pressure, constant-clearance and constant-thickness rolling of battery pole sheets, achieves on-line real-time control of position and pressure of the roller and the thickness of the battery pole sheet, ensures the arbitrary switch among the three control modes, thereby meeting higher requirement for the accuracy of battery pole sheets.

Description

technical field [0001] The invention relates to a rolling mill for rolling battery pole pieces, in particular to a rolling mill for controlling the accuracy of the battery pole piece through hydraulic means. Background technique [0002] The pole piece of the battery is one of the main components of the battery. The pole pieces of the same thickness are required to have a uniform thickness deviation. When connecting pole pieces of different thicknesses, a uniform transition is also required to maintain a uniform thickness of the pole pieces of the same thickness. . Therefore, the rolling required for battery thickness is relatively strict, and the precision required by the rolling mill is also relatively high. [0003] Chinese patents disclose a lot of rolling mills for battery pole pieces. For example, the following Chinese patents disclose technologies related to battery pole piece rolling mills: [0004] Patent number Patent name [0005] 200620127276.7 Lithium-ion bat...
