Processing and clamping method for big-diameter cathode roll vehicle

Abstract

The invention discloses a processing and clamping method for a big-diameter cathode roll vehicle. A process reservation section is processed on a cathode roll shaft end and is cooperated with a terminal pad to realize the quick clamping and disassembling of the cathode roll shaft clamping process. Before the cathode roll is assembled and welded, an outer square with a taper is processed on a shaft end reversed process section when a cathode roll core shaft part is processed; the center of the terminal pad is provided with an inner square hole with the taper; the inner square hole of the terminal pad is cooperatively assembled and connected with the process reservation section of the cathode roll shaft end by a bolt; and after the cathode roll vehicle finishes processing, the terminal pad is ejected out by a disassembling bolt and is quickly disassembled. According to the processing and clamping method for the big-diameter cathode roll vehicle, which is disclosed by the invention, squares are cooperated to bear a large torque, and a tool is tightly cooperated after the cooperation with a conical surface so as to avoid the phenomena of loosening and shaking. After processing is finished, the terminal pad is quickly disassembled by the disassembling bolt. The mass production, the lathing and the quick clamping and disassembling of the cathode roll can be realized by the fact that a technical chuck is reserved on the terminal pad and the shaft end, the lathing stability and the processing quality of the cathode roll are guaranteed, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a clamping method for large-diameter cathode roller lathe processing. Background technique [0002] With the rapid development of the electronics industry, the demand for high-quality copper foil is also increasing. At present, the method of producing copper foil at home and abroad generally adopts the electrolysis method, and the cathode roller is the core equipment for the production of copper foil by the electrolysis method. The cathode roller is a titanium cathode roller body, which has very stable acid resistance and is easy to peel off the electrolytic copper foil after electrolysis. [0003] At present, the manufacture of cathode rollers is basically a composite cathode roller made of spinning titanium cylinders or welded titanium cylinders and steel roller cores. The outer layers of cathode rollers are all welded by titanium materials, including titanium cylinders and...

AI Technical Summary

Problems solved by technology

[0005] The two commonly used clamping methods have the following disadvantages: the method of welding the connection plate at the shaft end is difficult to disassemble and cannot be used repeatedly, which is not conducive to mass production; the square reserved shaft end is used for assembly with the square hole of the connection plate The method is not closely matched, and there is a certain fit gap. When the cathode roller rotates and the cutting force is large, shaking occurs, which affects the processing quality of the product.
