An antirust device for sheet metal

Abstract

The invention discloses an antirust device for a metal plate. The device comprises an outer box body; a discharging box is arranged in a left side of the outer box body; a discharging cavity is formedin the discharging box; a metal plate is arranged in the discharging cavity; a slope is arranged below a left end wall of the discharging cavity; a discharging opening is formed in a right end wall of the discharging box; the metal plate falls on the slope, so that one part of the metal plate extends out of the discharge opening; a grabbing cavity is formed in a right side of the discharging box;and a grabbing assembly is arranged in the grabbing cavity. The device is convenient to use and has high automation degree, the metal plate is automatically grabbed and put into a phosphating box through the grabbing device, a rotary brush is arranged at a bottom in the phosphating box, the phosphating effect on a surface of a workpiece is greatly improved, the phosphating speed is increased, metal phosphating is uniform, the metal can be dried at the highest speed through the drying box, and the condition that phosphating effect is reduced due to the influence of time is avoided.

Description

technical field [0001] The invention relates to the field of antirust technology, in particular to an antirust device for metal plates. Background technique [0002] Metal antirust is a process that most enterprises will carry out now. There are many methods for metal antirust. Phosphating is a commonly used pretreatment technology, which is mainly used for phosphating on steel surfaces. Phosphating can also be applied to non-ferrous metal parts. Phosphating is a process in which chemical and electrochemical reactions form a phosphate chemical conversion film, and the formed phosphate conversion film is called a phosphating film. The purpose of phosphating is mainly to provide protection for the base metal, prevent the metal from being corroded to a certain extent, use it as a primer before painting, improve the adhesion and anti-corrosion ability of the paint film layer, and reduce friction in the metal cold processing process Lubrication. Most of the existing phosphating...

AI Technical Summary

Problems solved by technology

Most of the existing phosphating is put into the phosphating pool and after a period of time, the phosphating is completed, and then the workpiece is taken out, but the surface cannot completely contact the treatment liquid, which reduces the effect of phosphating on the surface of the workpiece, and takes too long , time-consuming and labor-intensive
