Zinc-nickel infiltrated layer anti-corrosion treatment tooling for rail fasteners

Abstract

The invention discloses a tool for performing preservative treatment on zinc-nickel seeping layers of steel rail fastener elastic strips. The tool comprises a suspension shaft and a plurality of charging baskets, wherein a column pipe core allowing the suspension shaft to penetrate and be suspended is arranged in the center of each charging basket; an opening of the next charging basket is covered by the bottom of the previous charging basket; the opening of the uppermost charging basket is covered by a cover net which is inserted into the suspension shaft; all the charging baskets and the cover net are locked by a locking mechanism on the suspension shaft. A plurality of parallel elastic strip supporting ribs for suspending the elastic strips are distributed in the charging baskets uniformly; clamping brackets for clamping the elastic strips are arranged at the two ends of each elastic strip supporting rib. The elastic strips are not hooked mutually, so the workload of manual separation is greatly reduced. Workpieces are placed neatly and orderly and one set of tool can load hundreds of elastic strips, so the charging quantity of the steel rail fastener elastic strips is increased, the workload of charging the workpieces into the tool is reduced, and the production efficiency of the zinc-nickel seeping layers is improved.

Description

technical field [0001] The invention relates to the improvement of anti-corrosion treatment technology for zinc-nickel infiltrated layer, and specifically refers to a kind of tooling specially used for anti-corrosion treatment of zinc-nickel infiltrated layer for a product with a special shape-track rail fastener clip. The tooling is used to load the clip workpiece and place it Used in the step of heating the impregnated layer in the drum. Background technique [0002] Metal anti-corrosion technology is mainly to form a protective layer through special treatment on the surface of the object, so as to slow down the damage or deterioration of the object under the action of various corrosive substances or environments, so as to prolong the service life of the object the goal of. Common metal anti-corrosion technologies mainly include electro-galvanizing, hot-dip galvanizing, carbonitriding, dacromet and zinc-nickel coating. One step in the zinc-nickel infiltration process is ...

AI Technical Summary

Problems solved by technology

[0003] For rail fastener clips, due to its complex shape, it is a dissimilated character "ω". If you put it into a tooling at will, and then put the tooling into the drum, the clip will be rolled during the rolling process of the drum. Hooked together, it is difficult to separate, and it takes a lot of time to manually separate; and the loading volume is also greatly reduced, both factors will affect the production efficiency of the zinc-nickel coating
