High-performance surface treatment device for steel bar base material used for bolt

Abstract

The invention discloses a high-performance surface treatment device for a steel bar base material used for a bolt. The high-performance surface treatment device comprises an acid pickling tank, a wireunreeling rotary disc, multiple conveying wire guide wheels, a sprinkling device, an exhaust device, an acid pickling tank first partition plate, an acid pickling tank second partition plate and a control panel. The acid pickling tank is a rectangular tank body, and the acid pickling tank first partition plate and the acid pickling tank second partition plate are vertically arranged in the acid pickling tank and divide the acid pickling tank into three independent cavities. By means of the high-performance surface treatment device for the steel bar base material used for the bolt, the surfacetreatment efficiency of the steel bar base material used for the bolt can be improved, the surface treatment quality is improved, surface treatment equipment can be used for being directly connectedwith wire drawing equipment in bolt production, the steel bar base material is directly guided into bolt production equipment after surface treatment, steps are saved, waste gas generated in the acidpickling process can be collected due to the arrangement of the exhaust device, subsequent treatment of the waste gas is facilitated, and damage of the acid pickling waste gas to the environment and the human body is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of bolt production, in particular to the technical field of a reinforcement substrate surface treatment device for bolts. 【Background technique】 [0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw, which needs to be matched with a nut to fasten two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. The raw material of bolts is generally wire. In order to improve the surface anti-rust and anti-corrosion performance of the wire, the surface of the wire is often treated. Pickling is a method of surface treatment of the wire. Pickling uses acid solution to remove scale and corrosion on the steel surface. The method of removing rust is called pickling. It is a method of cleaning metal sur...

AI Technical Summary

Problems solved by technology

Generally, the workpiece is immersed in an aqueous solution such as sulfuric acid to remove films such as oxides on the metal surface. The existing wire pickling equipment usually puts the whole coil of the wire directly into the pickling pool for pickling. The quality of pickling is poor, and pickling The efficiency is low, and the pickling step is cumbersome. After pickling, the wire needs to be taken out of the pickling tank and then drawn into the bolt production equipment
