Powder throwing magnetic attraction type metal bar polishing device

Abstract

The invention discloses a powder throwing magnetic attraction type metal bar polishing device, and belongs to the technical field of polishing machining of metal materials. An inwards-concave arc-shaped bearing and a pair of flow deflectors are arranged, a magnetic polishing roller is located above a particle falling cooling part, and a plurality of magnetic particles are arranged at the particle falling cooling part; and after an inner electromagnetic roller is powered on and magnetic, the outer wall of the magnetic polishing roller is magnetic, so that the magnetic particles are attached to the outer wall of the magnetic polishing roller, the magnetic particles are rubbed between the magnetic polishing roller and a metal bar, and the polishing effect is improved. Meanwhile, an air supply pipe is used for supplying air to the particle falling cooling part, gas pushes part of magnetic particles which are not magnetically attracted to the magnetic polishing roller to be thrown to the end wall of the metal bar, multi-point impact type damage is achieved on impurities such as oxide skin, and therefore subsequent polishing of the magnetic polishing roller is facilitated, in addition, water is used for leaching the magnetic particles, on one hand, dust is removed, and on the other hand, the effect of cooling the polished end face is achieved.

Description

technical field [0001] The invention relates to the technical field of grinding and processing of metal materials, and more specifically relates to a polishing device for throwing particles and magnetically attracting metal rods. Background technique [0002] Usually, the metal surface will be accompanied by dust, oil, scale, rust, pollutants, salt or loose old paint film, among which scale is the most common but most easily overlooked part. Oxide scale is a layer of dense oxide layer produced during high-temperature forging and pressing of steel. It is usually attached more firmly, but it is more brittle than steel itself, and it is a cathode, which will accelerate metal corrosion. If these substances are not removed and painted directly, it will inevitably affect the adhesion and anti-corrosion ability of the entire coating. [0003] However, the polishing devices on the market cannot fully polish the metal rod, and the pressure between the grinding wheel and the rod wall...

AI Technical Summary

Problems solved by technology

Oxide scale is a layer of dense oxide layer produced when steel is forged and pressed at high temperature. It is usually attached more firmly, but it is more brittle than steel itself, and it is a cathode, which will accelerate metal corrosion.

If these substances are not removed and painted directly, it will inevitably affect the adhesion and anti-corrosion ability of the entire coating.

[0003] However, the polishing devices on the market cannot fully polish the metal rod, and the pressure between the grinding wheel and the rod wall is small, especially for the scale with strong adhesion, it is more difficult to remove, and then simply use grinding It is difficult to ensure that the wheel can achieve a good impurity removal and polishing effect on the outer wall of the bar
