Centrifugal-type small part hot galvanizing system with parts

Abstract

The invention discloses a centrifugal-type small part hot galvanizing system with parts. The hot galvanizing system comprises a track mechanism, a feeding area, a galvanizing area and a discharging area, wherein the feeding area, the galvanizing area and the discharging area are arranged along the track mechanism. The track mechanism is movably provided with at least two feeding mechanisms. A centrifugal area is arranged at the terminal of the galvanizing area. The centrifugal area comprises centrifugal equipment and a grabbing mechanism. The grabbing mechanism can transfer charging baskets containing the parts to be machined to the grabbing mechanism from the feeding mechanisms for centrifugal galvanizing. According to the hot galvanizing system, the galvanizing area and the centrifugal area are adjacently arranged, the structure is simplified, and the galvanized machined parts can enter the centrifugal area at once for centrifugal galvanizing. The galvanizing effect is good, the process of repeatedly heating molten zinc to a designated temperature is omitted, and the energy-saving and cost-reducing effects are obvious. Moreover, the phenomenon that the galvanizing effect is influenced due to the fact that the machined parts are polluted when being transferred to the centrifugal area from the galvanizing area is avoided, so that production efficiency is improved, the coating quality is good and safety performance is high.

Description

technical field [0001] The invention belongs to the field of hot-dip galvanizing, in particular to a centrifugal type hot-dip galvanizing system for small parts with parts. Background technique [0002] In order to ensure the aesthetics and rust resistance of metals, alloys and other materials, hot-dip galvanizing is usually performed on the surface of the material. Hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing. It is an effective metal anti-corrosion method. It immerses the pre-treated material in a molten zinc solution at about 530°C. After complex physical and chemical actions, a zinc layer is attached to the surface of the material to achieve the purpose of anti-corrosion.

AI Technical Summary

Problems solved by technology

[0003] At present, in the hot-dip galvanizing production line for small parts, multiple barrels containing parts to be processed are usually moved synchronously on the conveying track, passing through the feeding area, galvanizing area, centrifugal area and discharging area in sequence, in order to ensure the galvanized The quality needs to ensure the effective reaction time of the barrel in the zinc liquid pool, so the speed of the track rotation is relatively slow. Since all the barrels move synchronously with the track, the speed of the track remains the same throughout the process, and it is impossible to complete the galvanized single The speed of the barrel is controlled, which results in a long time for the barrel to move from the centrifugal area to the discharge area. The long-term transportation process makes the temperature of the barrel plummet, and the zinc liquid in the barrel is also transformed from liquid to solid. After the barrel is unloaded in the discharge area, when it enters the feed area again, the barrel must be heated to about 530°C, which increases the heating time and energy consumption, and the whole process takes a long time. low work efficiency

[0004] When the workpieces to be processed enter the galvanizing area for galvanizing procedures, it is inevitable that impurities will be brought into the zinc liquid pool filled with zinc liquid. As multiple batches of workpieces to be processed are immersed in the zinc liquid pool for galvanizing, the zinc liquid Impurities floating in the pool are also accumulating more and more. If the zinc liquid pool is not cleaned in time, not only the effect of galvanizing will be affected, but also the entire shape and size of the workpiece will be greatly affected.

At present, the surface of the zinc liquid pool is usually scraped to remove impurities manually, but the scraping effect is not good, and the temperature of the zinc liquid pool is extremely high, and a slight error in the operation will cause unnecessary damage to the body of the workers.

[0005] The traditional hot-dip galvanizing production system usually sets the galvanizing area and the centrifugal area separately. The distance between the centrifugal area and the galvanizing area is relatively long. Longer, and the solidification speed of the zinc liquid is faster, the zinc liquid on the surface of the workpiece is almost semi-solidified when it reaches the centrifugal area, the centrifugal effect is greatly reduced, and the excess zinc liquid thrown out during the centrifugation cannot be effectively used for secondary use. Excess zinc liquid must be reheated before it can be reused, which increases energy consumption and reduces production efficiency
