Bar rust cleaning machine and rust cleaning method

Abstract

The invention discloses bar stock derusting machine and the descaling. The device includes framework, power transmission and the rolling brush device, the power transmission and the rolling brush device are placed on said framework. The apparatus is characterized by: contact roller clamping transportation device is also set up on the framework, the said contact roller clamping transportation device includes big and small umbrella gear, main roller, assistant roller, assistant roller bracket and assistant roller adjusting handle, the said rolling brush device involves rolling brush motor, belt pulley and triangular belt. Sent the stuff between the main roller and the assistant roller artificially, the roller rotates automatically after clamps the bar stock, and the bar stock is proofreaded by the assistant roller and is removed rust by the rolling brush between the main roller and the assistant roller. The invention has the following advantages: the bar stock could be feeded automatically and there is no descaling dead corner. It can be applied to removing rust for the face of the bar stock with different diameter and certain degree of bend, and the descaling process is pollution-free, low energy consumption, low labor intensity and low cost of production.

Description

technical field [0001] The invention relates to a bar descaling machine and a descaling method for surface treatment of ferrous metals and nonferrous metals. Background technique [0002] Traditional rust removal methods for metal bars include manual rust removal and pickling rust removal. The former rust removal workers have high labor intensity, and the rust powder and dust emitted during the rust removal process seriously pollute the environment and endanger the health of the operators. The derusting effect is average; although the derusting effect of the latter is relatively ideal, the large amount of waste acid produced will seriously pollute the water body, the upper soil, corrode the equipment, and consume a lot of energy during the production process, resulting in high production costs. Also have some derusting machinery to occur recently, be 02280759.4 as the patent No., the invention called " derusting machine " discloses a kind of mechanical derusting device that ...

[0002] Traditional rust removal methods for metal bars include manual rust removal and pickling rust removal. The former rust removal workers have high labor intensity, and the rust powder and dust emitted during the rust removal process seriously pollute the environment and endanger the health of the operators. The derusting effect is average; although the derusting effect of the latter is relatively ideal, the large amount of waste acid produced will seriously pollute the water body, the upper soil, and corrode the equipment, and consume a lot of energy during the production process, resulting in high production costs.

Also have some derusting machinery to occur recently, be 02280759.4 as the patent No., the invention called " derusting machine " discloses a kind of mechanical derusting device that is used for metal bar (pipe) surface, the brush that is arranged on the main shaft will pass through main shaft The rust on the metal rod (pipe) is cleaned. Since the rolling feeding device of the derusting machine is only set at the outlet end of the bar, and the brush is set in the middle of the main shaft, there is a dead angle for rust removal. There will be a certain distance at the head end without rust removal, resulting in waste of bar stock
