A physical friction derusting device for h-shaped steel

Abstract

The invention discloses a physical friction derusting device for H-shaped steel. The derusting box, the left and right surfaces of the derusting box are provided with left and right through derusting chambers, and the derusting box is provided with gear chambers with symmetrical front and rear positions, and the front and rear walls of the gear chamber are rotatably connected with The motor shaft, the rear end of the motor shaft on the rear side is connected to the first motor fixed in the rear wall of the gear cavity on the rear side, which can realize comprehensive physical derusting of H-shaped steel and can adapt to different sizes H-shaped steel, you only need to place the H-shaped steel on the roller during operation, which can basically realize automatic feeding, positioning and grinding, and the labor intensity is low. Because it is a physical derusting method, it will not pollute the environment and is more environmentally friendly. .

Description

technical field [0001] The invention relates to the related technical field of building steel, in particular to a physical friction derusting device for H-shaped steel. Background technique [0002] H-shaped steel is an economical cross-section high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Section steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structure weight; [0003] H-beams will inevitably encounter rust problems during normal use or storage. For H-beams that have already been rusted, they must be derusted before they can be used. Therefore, rust removal of H-beams often needs to be encountered during production. However, H-shaped steel has more surface, so it will be more troublesome to derust, and there may be problems such as low efficiency or hig...

Problems solved by technology

[0003] H-beams will inevitably encounter rust problems during normal use or storage. For H-beams that have already been rusted, they must be derusted before they can be used. Therefore, rust removal of H-beams often needs to be encountered during production. However, H-shaped steel has more surface, so it will be more troublesome to derust, and there may be problems such as low efficiency or high labor intensity. For chemical derusting, it may not be necessary to consider the surface relationship of H-shaped steel, but chemical derusting Rust may cause environmental pollution
