Description

Technical Field

[0001] The invention relates to the field of copper foil manufacturing, in particular to a tool for hot-loading a titanium cylinder of a cathode roller, a key component in copper foil manufacturing equipment. Background Art

[0002] Electrolytic copper foil is one of the basic materials of the electronics industry and a new copper foil production method developed in recent years. The cathode roller is the main component in the production of electrolytic copper foil. Titanium cathode rollers are generally used for production. The titanium cathode roller rotates at a constant speed in the copper electrolytic solution. At the same time, a very high current passes through the copper row to the graphite carbon brush, then to the conductive ring, the cathode roller shaft, and then to the surface of the titanium cathode roller. In order to obtain a large area and sufficient thickness of electrolytic copper foil on the roller surface, the cathode roller working current must meet the standard requirements; therefore, the conductivity of the titanium cathode roller is very high. In order for the titanium cathode roller surface to have higher conductivity, the inner surface of the titanium roller and the outer surface of the steel core must fit tightly so that the titanium roller surface can be evenly energized, thereby improving the production quality of the copper foil;

[0003] At present, the titanium roller and the steel roller core are assembled by hot-fitting to achieve an interference fit. Due to the dimensional accuracy and structural limitations of the titanium cathode roller, and the limitations of the hot-fitting environment of the titanium cylinder and the steel roller core, hot-fitting requires the use of tooling to ensure the design requirements. At the same time, due to the high processing cost of the titanium cylinder and the small processing allowance of the titanium cylinder, the coaxiality of the titanium cylinder and the steel roller core must be ensured during hot-fitting. Based on the above conditions and in accordance with the structural requirements of the titanium cathode roller, the corresponding hot-fitting tooling is designed to ensure the matching size of the titanium cylinder and the steel roller core during hot-fitting. Summary of the invention

[0004] The purpose of the present invention is to provide a hot-fitting tool for a titanium cylinder which ensures the roundness of the entire titanium cylinder, the coaxiality of the hot-fitting of the titanium cylinder and the steel core, the end face size of the hot-fitting of the titanium cylinder and the steel core, and the fitting rate between the inner surface of the titanium cylinder and the outer surface of the steel core.
