Metal copper surface oxide skin treatment process

Abstract

The invention relates to the technical field of metal surface treatment, in particular to a metal copper surface oxide skin treatment process. A treatment device utilized in the metal copper surface oxide skin treatment process comprises a base, a ring cylinder, a clamping block, a cutter and a controller, wherein the ring cylinder is fixedly connected with the upper end of the base; the axis of the ring cylinder is parallel to the upper end of the base; a strip-shaped groove is formed in the inner wall of the ring cylinder; the cutter is slidably connected into the strip-shaped groove; and No.1 springs are also arranged in the strip-shaped groove. According to the treatment device utilized in the metal copper surface oxide skin treatment process, metal copper is driven by a No.1 motor toslide along a No.1 sliding rod and driven by a No.2 second motor to rotate; through the cooperation between the metal copper sliding and rotating processes, oxide skin on the surface of the metal copper falls off faster and more thoroughly under the scraping action of the cutter; therefore, the metal copper surface oxide skin removing effect is improved, and then the quality of the metal copper isimproved; and meanwhile, the metal copper surface oxide skin treatment process has the advantages of being environmentally friendly and free of pollution.

[0002] Copper and copper alloy products and parts can form oxides with oxygen in the air at room temperature. After processing and heat treatment, it is easier to oxidize at high temperature, and a thick and dense oxide scale will be formed, which will be used for subsequent processing and processing. It is very difficult to use; the traditional process is to pickle copper and copper alloys to achieve the purpose of removing the oxide layer; the use of chemical treatment reagents can penetrate, loosen, soften, and clean high-temperature scale and copper rust; copper chemistry Polishing is an environmentally friendly polishing process on the surface of copper and its alloys. After chemical polishing, the oxide skin on the copper surface is removed; when chemically polishing copper and copper alloy parts, for some batch parts manufacturers, The number of copper and copper alloy parts is large, and the parts are piled up and squeezed together, which may easily cause the local contact surface to be uncleaned, resulting in incomplete removal of the oxide skin on the surface of the metal copper. Therefore, the market urgently needs a high-efficiency, environmentally friendly Oxide skin treatment process on metal copper surface with good cleaning effect

[0003] There are also some technical solutions about the oxide scale treatment process on the surface of metal copper in the prior art. For example, a Chinese patent with the application number CN201810178939.5 discloses a process for the oxide scale treatment on the surface of copper metal, which includes the following steps: preparatory work , chemical polishing, water washing, paving, drying and cleaning fluid maintenance; the removal device used in this process includes a polishing module, a material frame, a paving module and a drying module; the polishing module includes a box, an ultrasonic generator, a heating tube, Pool and closing plate assembly; there are chutes on both sides of the box to cooperate with the sliding of the closing plate assembly; one end of the closing plate assembly is fixed with a permanent magnet block; the outer side of the box is provided with a guide rail corresponding to the chute; the traction magnet is slidably connected to the guide rail; the traction magnet Sliding is used to open or close the bottom of the box; this technical solution passes the airflow through the material box, making the parts turn in the cleaning liquid, overcoming the deficiency of manual turning; by using the cleaning liquid to separate layers, and separately remove the sediment containing dirt The technology of cleaning liquid improves the utilization rate of cleaning liquid; however, when the mass of the parts of this technical solution is large, the air flow cannot drive the parts to turn in the cleaning liquid, so that the partial contact surface of the parts is not cleaned cleanly, which in turn causes the limitation of this technical solution sex
