Derusting equipment for hardware processing

Abstract

The invention discloses derusting equipment for hardware processing. The derusting equipment for hardware processing comprises a tank and a support, wherein the tank is fixed to the top end of the support; reinforcing steel bar holes are formed in two sides of the tank; a lifting assembly is fixed to the bottom part in the tank; and a derusting device is fixedly arranged in the tank. According tothe derusting equipment for hardware processing provided by the invention, a motor drives a rotary shaft to quickly rotate, so that a derusting brush and reinforcing steel bars rub continuously, and rust stains on the peripheries and in screw threads of the reinforcing steel bars are cleared; through a lifting assembly, a friction force between the reinforcing steel bars and the derusting brush can be increased; and the height can be adjusted according to the thickness of the reinforcing steel bars, so that the derusting equipment for hardware processing is wide in use range, remarkable in derusting effect, convenient to operate, convenient and practical.

Description

technical field [0001] The invention relates to the technical field of hardware processing, in particular to rust removal equipment for hardware processing. Background technique [0002] Rust is a corrosion product mainly composed of hydroxides and oxides produced by metal corrosion in the atmosphere. In mechanical processing, it is often necessary to remove raw materials or parts. [0003] Traditional manual rust removal is labor-intensive, low in efficiency, and poor in labor protection, while chemical rust removal usually uses strong acids, which can chemically react with rust and metal oxides to form soluble salts, thereby achieving the purpose of rust removal. There are drawbacks to rust removers. That is, the generation of a large amount of hydrogen gas during the treatment process will cause hydrogen embrittlement of metals and other materials, which will cause the mechanical properties of metal materials to decline and affect the strength of the material itself. ...

[0003] Traditional manual rust removal is labor-intensive, low in efficiency, and poor in labor protection, while chemical rust removal usually uses strong acids, which can chemically react with rust and metal oxides to form soluble salts, thereby achieving the purpose of rust removal. Rust removers have drawbacks

That is, the generation of a large amount of hydrogen gas during the treatment process will cause hydrogen embrittlement of metals and other materials, which will cause the mechanical properties of metal materials to decline and affect the strength of the material itself.

[0004] After searching the Chinese patent document CN207668195U, a coiled steel bar rust removal device is disclosed, which includes a box body, a rust removal wheel set and a bracket. The derusting wheel set, the derusting wheel set is elastically set, the device is easy to use and reduces labor, but when this device is derusting the steel bar with a large difference in thickness, it only depends on the expansion and contraction of the spring to change the relationship between the steel bar and the derusting machine. The distance of the rust device is limited, and long-term use may damage the spring. In addition, when contacting the steel bar for rust removal, there is no other external force to squeeze, which will cause unclean and incomplete rust removal, increase workload and waste resources. For this reason, We propose a derusting equipment for metal processing
