Phosphating method and device for metal wire surface treatment

Abstract

The invention relates to a phosphating method and device for metal wire surface treatment. The device comprises a base, three box sets are arranged on the top face of the base in a matched manner, each box set comprises an upper box and a lower box, the bottom of each upper box is open, the top of each lower box is open, the three boxes located on the lower portion are fixedly connected, the threeboxes located on the upper portion are fixedly connected, a second lifting device can control the three boxes on the upper portion to move upwards, a window is formed in the top end of the box located on the upper portion in each box set, and a sealing cover is hinged to the inner wall of one side of each window. A metal wire penetrates a through hole in the leftmost side, then sequentially penetrates multiple through holes in the middle and finally penetrates out of a through hole in the rightmost side, through driving of a power device, and the metal wire moves from the left side to the right side, and in the phosphating process, the box sets are in the sealed state, influences of external impurities on metal wire phosphating are avoided, due to the sealed state, volatilization of a phosphating solution is reduced, dip dyeing type phosphating is adopted, and the surface of the metal wire can be more uniform in the phosphating process.

Description

technical field [0001] The invention belongs to the technical field of metal wire surface treatment, in particular to a phosphating method and device for metal wire surface treatment. Background technique [0002] Metal wire products with different purposes and different wire diameters must be drawn in various forms during the production process. For example, bead wires need to be dry drawn; steel cords and hose steel wires need to be dry drawn first, and then intermediate heat After wet pull. No matter what kind of drawing process it is, the surface of the wire rod must be treated with the bottom layer before drawing. The bottom layer treatment will help the surface of the wire rod to quickly absorb lubricant and form a good lubricating layer, thereby ensuring the smooth progress of the drawing process; Phosphating coating occupies a large proportion in lubricating bottom treatment, but in the current phosphating operation, the dipping length of phosphating solution cannot...

No matter what kind of drawing process it is, the surface of the wire rod must be treated with the bottom layer before drawing. The bottom layer treatment will help the surface of the wire rod to quickly absorb lubricant and form a good lubricating layer, thereby ensuring the smooth progress of the drawing process; In the lubricating bottom layer treatment, phosphating coating occupies a large proportion, but in the current phosphating operation, the dipping length of phosphating solution cannot be adjusted, which has a negative impact on the subsequent drawing operation
