Automatic device for steel pipe hot-dip galvanizing and pickling and control method

Abstract

The invention belongs to the technical field of hot-dip galvanizing and pickling, and particularly relates to an automatic device for steel pipe hot-dip galvanizing and pickling and a control method. The automatic device comprises a feeding trolley, an automatic hanging bracket, an intelligent trolley, a track, a steel pipe discharging rack, a pickling tank, a rinsing tank and a plating assisting tank; the intelligent trolley is arranged on the track, and the two ends of the automatic hanging bracket are correspondingly connected with the intelligent trolley through lifting mechanisms; the pickling tank, a rinsing tank and a plating assisting tank are sequentially arranged below the track in the feeding direction, bosses are arranged on the inner sides of the pickling tank, the rinsing tank and the plating assisting tank, the feeding trolley is arranged below the feeding end of the track, and the steel pipe discharging rack is arranged below the discharging end of the track. Compared with the prior art, the automatic hanging bracket is adopted to control opening and closing of a hanging arm, the step of manually placing a workpiece to be plated into the hanging bracket is eliminated, the bosses are utilized to achieve the steel pipe turning function, impurities generated by acid pickling are removed, the pressing device of the automatic hanging bracket is utilized, acid control is convenient, and continuous and stable conveying of steel pipes is achieved through the steel pipe discharging rack.

Description

technical field [0001] The invention belongs to the technical field of hot-dip zinc pickling, in particular to an automatic device and a control method for hot-dip zinc pickling of steel pipes. Background technique [0002] Hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing: it is an effective metal anti-corrosion method, mainly used in metal structure facilities in various industries. It is to immerse the rust-removed steel parts in the molten zinc at about 450 ° C, so that the surface of the steel parts will be attached with a zinc layer, so as to achieve the purpose of anti-corrosion. The first process of hot-dip galvanizing is pickling and rust removal, and then cleaning. If these two processes are not thorough, they will leave hidden dangers for corrosion protection, so they must be dealt with thoroughly. In the pickling process step pickling-washing-helping plating process, the transfer of the workpiece adopts the method of manual operation...

Problems solved by technology

The first process of hot-dip galvanizing is pickling and rust removal, and then cleaning. If these two processes are not thorough, they will leave hidden dangers for corrosion protection, so they must be dealt with thoroughly.

In the pickling process step pickling-washing-helping plating process, the transfer of the workpiece adopts the method of manual operation and hanging, put the workpiece to be plated in the hanger, check the pickling condition of the surface of the workpiece regularly, and determine the pickling condition at each The pickling time in the pickling tank is pickling one by one, and then water washing-assisted plating. The operator is in the environment of acid mist and smoke for a long time, which has a great impact on his health. All processes are controlled manually. The product quality is uneven and the production efficiency is low
