Steel wire phosphating and drying device

Abstract

The invention provides a steel wire phosphating and drying device which comprises a phosphating box, a drying box, a manual one-way valve, a drainage pipe, a connecting air pipe and an air collecting and guiding cover, the drying box is installed on the right side of the phosphating box, a heating box is installed on the right end face of the drying box, an air blower is installed on the upper side of the heating box, and the air collecting and guiding cover is installed on the lower side of the heating box. A supporting bottom plate is transversely installed on the lower side of the interior of the drying box, multiple sets of water seepage through holes are formed in the supporting bottom plate, a hot air main pipe is installed on the upper side of the supporting bottom plate, hot air branch pipes are installed on the upper side of the annular side face of the hot air main pipe, and hot air nozzles are installed on the inner sides of the annular side faces of the hot air branch pipes. The steel wire phosphating device solves the problems of low drying speed and low drying efficiency, is reasonable in structure, facilitates phosphating treatment on steel wires, can quickly dry the phosphated steel wires, and is high in drying speed and high in drying efficiency.

Description

technical field [0001] The invention relates to a steel wire phosphating drying device, which belongs to the technical field of steel wire processing. Background technique [0002] Spring steel wire is a kind of steel wire used to make springs or steel wire parts. According to the different uses of the spring, there are various types of spring steel wires required for springs, such as spring steel wires for mattress springs with lower requirements, spring steel wires for shock absorbers, spring steel wires for suspension springs, and spring steel wires for engine valves. Spring steel wire and spring steel wire for camera shutter, etc. Although there is no unified standard classification name, the quality requirements of these steel wires are different. Spring steel wire can also be classified according to the manufacturing process, such as raw-drawn spring steel wire (without lead bath quenching treatment before drawing), lead-quenched spring steel wire, galvanized spring s...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, after the phosphating treatment of the steel wire, the surface is usually dried by natural air drying, and there is no special drying device for drying the surface, the drying speed is slow and the drying efficiency is low, which is urgently needed A steel wire phosphating drying device to solve the above-mentioned problems
