Fastener surface treatment galvanization equipment

Abstract

The invention discloses fastener surface treatment galvanization equipment which comprises a special-shaped base, wherein a fastener clamping seat is fixedly connected to the top of the special-shaped base, an electric sliding frame is movably connected to the top of the special-shaped base, an electric telescopic rod is fixed to the top of the electric sliding frame, a special-shaped connecting frame is fixedly connected to the bottom of the electric telescopic rod, and a micro telescopic rod is fixed to the inner wall of the special-shaped connecting frame. According to the fastener surface treatment galvanization equipment, a motor is arranged to drive a rotating shaft rod and a grid steel plate to rotate, so that a fastener entering a passivating treatment box can turn over in a passivating solution along with rotation of the grid steel plate, and the passivating time of the fastener can be controlled by adjusting a rotating period of the rotating shaft rod; the galvanization equipment is good in passivating treatment effect, the passivating solution can make uniform contact with the surface of the fastener, and the treatment time is convenient to control, so that the passivation effect is good, passivation holes are not prone to occurring, and therefore, the quality of the fastener is improved, and long-term use of the fastener is facilitated.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a galvanizing equipment for surface treatment of fasteners. Background technique [0002] Galvanizing refers to the surface treatment technology of coating a layer of zinc on the surface of metal, alloy or other materials to play the role of beauty and anti-rust. The main method is hot-dip galvanizing. Zinc is easily soluble in acid and alkali. , so it is called an amphoteric metal. Zinc hardly changes in dry air. In humid air, a dense basic zinc carbonate film will be formed on the surface of zinc. The zinc coating is passivated, dyed or coated to protect the light. With the development of galvanizing technology and the adoption of high-performance galvanizing brighteners, galvanizing has entered protective-decorative applications from purely protective purposes, but the existing galvanizing Zinc equipment also has certain defects, such as: [0003] 1. The passivatio...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a kind of fastener surface treatment galvanizing equipment, to solve the passivation treatment effect proposed in the above background technology is not good, the passivation liquid can not evenly contact the surface of the fastener, the treatment time is not easy to control, It is prone to passivation loopholes, which is not conducive to the long-term use of fasteners, and is not convenient for batch galvanizing. Ordinary galvanizing equipment cannot clamp fasteners in batches, and the clamping work efficiency is low, which is not conducive to large-scale fasteners. Mass production is not conducive to galvanizing equipment suitable for galvanizing of small parts such as fasteners. At the same time, the heating and heat preservation effect of the zinc liquid is not good. The electric heating wire is usually located inside the zinc liquid, which makes the heating not uniform enough, and the processing box does not have Insulation effect, resulting in the rapid loss of heat of the zinc liquid
