Aluminum-like rod surface scraping mechanism

Abstract

The invention discloses an aluminum-like rod surface scraping mechanism. A main shaft for positioning an aluminum rod is arranged on a base, axially locked on the base and provided with a positioning hole through which the aluminum rod can penetrate, a scraping disc which can peripherally rotate relative to the main shaft is arranged on the main shaft, a concave cavity is arranged on the axial end surface of the scraping disc, the cavity opening of the concave cavity is fixedly connected with a cover plate on which a plurality of rolling, centering and scraping devices for the aluminum rod are distributed, a plurality of centrifugal weighting devices matched with the rolling, centering and scraping devices are evenly distributed in the concave cavity, one end of each rolling, centering and scraping device penetrates into the concave cavity to be peripherally connected with a centrifugal weighting device, one end of the main shaft penetrates through a central hole arranged on the coverplate, and the end part is arranged close to the other end of the rolling, centering and scraping device. The invention is beneficial to simplifying the surface treatment process of the aluminum rod,improving and maintaining the original metal structure state of the aluminum rod, improving the yield and decreasing the production cost.

Description

technical field [0001] The invention relates to a device for removing an oxide layer on the surface of a metal rod, in particular to a scraping mechanism for imitating the surface of an aluminum rod. The invention can also be used for the treatment of the oxide layer on the surface of metal rods such as copper rods and iron rods. Background technique [0002] There are several ways to remove the surface oxide layer of the known metal rod circle: 1. Peeling die: with a certain peeling cutting cone angle, the two ends of the peeling die are positioned and guided, and under the traction of the front-end power, the surface of the metal rod is continuously After peeling, the surface of the metal rod is in a pure state. The disadvantage of this method is that it requires a lot of traction when peeling, and the traction is limited by the production process. 2. Mechanical scrubbing process: In this method, before scrubbing, the metal rod is first pulled to remove the oil film on th...

The disadvantage of this method is that it requires a lot of traction when peeling, and the traction is limited by the production process

The disadvantage of this method is that the steel wire brush wears quickly and the mechanical failure rate is high. During the scrubbing process, the heat generated by the friction between the metal rod and the brush will cause the surface of the metal rod to re-form an oxide layer, and at the same time, the friction will generate electrostatic adsorption of dust, and The mechanical noise is large, which has a great impact on the surface quality of the metal rod after brushing

The above two methods can no longer meet the technical requirements of removing the oxide layer on the surface of the metal rod disc at the present stage
