Description

Device for galvanizing small-size metal parts

Technical Field

The utility model belongs to the technical field of hot dip galvanizing equipment, and particularly relates to a device for galvanizing a small-sized metal part.

Background

The hot galvanizing process is to immerse the rust-removed steel piece in molten zinc liquid at about 500 ℃ to adhere a zinc layer to the surface of the steel piece, thereby achieving the aim of corrosion prevention.

Based on the good performance of the hot galvanizing layer, small-size parts, nuts and the like of metal also begin to select hot galvanizing technology, and the material of the hot galvanizing layer can be changed from stainless steel to ferrous metal, so that the purposes of corrosion resistance and rust resistance are met while the cost is reduced, and the strength of a fastener is enhanced.

The processing technology of the hot dip galvanized small-size part comprises the following steps: raw material-small-size part matrix heat treatment-cleaning-drying-hot galvanizing. Because the residual zinc water remains on the surface of the small-size part after the small-size part is hot galvanized, the small-size part is unqualified in size and poor in appearance, the residual zinc water on the surface of the small-size part needs to be removed, a centrifugal machine can be selected, and the residual zinc water can be removed under the action of centrifugal force. However, the process from hot galvanizing the small-sized part to removing residual zinc water comprises the following steps: (1) Placing a certain amount of small-sized parts into a plating basket, then placing the plating basket into a zinc water tank, shaking the plating basket for a period of time, taking the plating basket out of the zinc water tank, and transferring the plating basket to centrifugal equipment; (2) Removing residual zinc water on the surface of the small-size part under the centrifugal action; (3) The centrifugation is cut off and the small-sized parts are transferred from the centrifugation device to the cooling device. It follows that the process requires the basket to be manually placed in a zinc bath and removed, and then the small-sized parts poured into a centrifuge. The defects of the traditional plating basket are that: 1. the small-size parts cannot be automatically poured into the centrifugal machine, and manual assistance is needed; 2. the basket is also manually assisted by shaking for a period of time after the basket is lifted out of the zinc bath. Because the temperature around the zinc water tank is high, the environment is poor, the zinc water tank is unfavorable to the health of workers, the labor intensity is high, the manual action is slow, and the working efficiency is low. 3. The existing plating basket has the defects of limited size, limited one-time galvanization quantity and low production efficiency.
