Problems solved by technology

Due to the restrictions on the deformation of the pipe wall thickness during the processing of the above two equipments, neither of the two processes can meet the high-precision requirements of customers for this product. For a long time, the copper pipes for high-precision magnetron anode cylinders used in China are from Imported from abroad, there is no copper pipe processing enterprise in China that has developed a processing method and process that achieves high precision of the pipe

Embodiment 1

[0013] A. Select high-quality electrolytic copper raw materials, the copper content of which is 99.90-99.97%. After the tube billet is cast in a submerged continuous furnace, it is milled on the surface, rolled by a three-roll planetary rolling mill, and then combined with single drawing. Stretching, the size is controlled at an outer diameter of Φ42-44mm, a wall thickness of 3.1-4mm, an inner diameter of Φ35.8-36mm, and the state is controlled as a y state; the copper tube made by the previous process is drawn through the crawler and cut to length Cut off and remove the burrs at both ends, and use pressure gas to purge the copper foam in the pipe during sawing;

[0014] B. Take the copper tube that has been produced in the above process and inject an appropriate amount of special lubricating oil, put the copper tube on the mandrel set on the four-high rolling mill, send the copper tube into the rolling wheel through the conveying wheel, and start the rolling of the finishing r...

Abstract

The invention relates to a processing technique for a copper tube used by a high precision magnetron anode cylinder. The invention is characterized in that the invention selects copper material with a copper content of 99.90 to 99.97 percent, adopts surface milling, three-planetary mill rolling, combined pulling and single stretching after undercurrent continuous furnace casting a tube rough, controls the state into a y state; then cuts off the burrs at two ends through track pulling, dimension fixing and cutting off, uses a pressure gas to blow and sweep the copper foam moistened in the tube; injects a specific lubricant with a proper amount on the copper tube and sleeves the copper tube on a mandrel rod of a four-high mil, controls the feeding speed of a feeding wheel within a range of 15 to 30m / h; injects enough lubricant during a rolling process, controls the discharging speed of the four-high mill within a range of 20 to 25m / h; when a finishing mill unit rolls partial products normally, stops the machine and fetch a section to exam the outer diameter, the inner diameter and the numerical value of the wall thickness and adjusts the dimensions of a finishing wheel and a slideway according to the examination result; cleans the finishing copper tube and removes the residual oil stain inside and outside the copper tube; fixes the dimension and saws, as well as cuts off the burrs at two ends and uses a drying gas to blow and sweep the inside and the outside of the tube.

Description

technical field [0001] The invention relates to a copper tube processing technology for a high-precision magnetron anode cylinder. Background technique [0002] In the prior art, there are two processing methods for ordinary copper pipes. One is the original extrusion cold rolling process, that is, semi-continuous casting-sawing to length-heating perforation, extrusion-Pilger two-roll cold rolling-combined drawing Pull-coil pull or straight pull-straighten cutting. The other is a short-process energy-saving processing method newly developed in recent years, referred to as the continuous casting and rolling method, that is, submerged horizontal continuous casting-blank surface milling-three-roll planetary rolling mill-large coil rewinding-combined drawing - High speed coil pulling - straightening and cutting. The difference between the two processes is only in energy consumption and finished product rate, but in terms of the precision of processing general copper pipes, suc...
