Abstract

The invention relates to a four-roller finishing mill, and belongs to the technical field of metallurgical machines. The four-roller finishing mill comprises a rack, a motor, a composite gear box, two universal joint shafts and two supporting rollers arranged in parallel, the composite gear box is connected with the motor through a coupling, one ends of the two universal joint shafts are connected with the composite gear box, and the supporting rollers are connected with the other ends of the universal joint shafts. Two work rollers are arranged between the two supporting rollers. A feeding press plate is arranged between the work rollers. A pressing-down device is arranged on the upper portion of the rack, and comprises a pressing-down motor, a worm gear and a worm. The worm is fixed to the rack through a nut. A pressure sensor is arranged at the bottom of the worm. The output end of the pressure sensor is connected with a control system. The worm gear is connected with a rotary encoder. The output end of the rotary encoder is connected to the control system. Through the four-roller finishing mill, the rolling of 0.005mm fold foil which can be achieved previously by multi-roller mills with 12 rollers or 20 rollers can be achieved, energy is greatly saved, and the operation is simplified.

Description

technical field [0001] The invention relates to a four-high finish rolling mill, which belongs to the technical field of metallurgical machinery. Background technique [0002] Gold foil, silver foil, and copper foil are widely used, and are usually obtained by multi-pass rolling on a four-roll rolling mill. However, the rolling limit thickness of the traditional four-roll rolling mill can only reach 0.02mm, which is no longer enough to meet the needs. In order to achieve a rolling thickness of 0.005 mm or even thinner, it is currently necessary to use multi-roll rolling mills such as 12-roll and 20-roll for rolling, which leads to high manufacturing costs and serious waste of resources and capabilities. Contents of the invention [0003] The technical problem solved by the invention is to propose a four-roll finishing mill capable of manufacturing a thickness of 0.005mm. [0004] In order to solve the above-mentioned technical problems, the technical solution proposed by ...
