Description

A stainless steel air duct processing and welding equipment technical field [0001] The present invention relates to the technical field of air duct welding, in particular to a stainless steel air duct processing and welding equipment. Background technique Stainless steel air duct has excellent physical and chemical properties such as corrosion resistance, heat resistance and high strength, and is mainly used for air tightness. In terms of process exhaust systems, waste exhaust systems, and smoke and dust removal systems with high performance requirements, the stainless steel air duct has different shapes. It is mainly divided into two types, one is circular and the other is rectangular. It is complicated, so in the process of application, in addition to the requirements of the installation site environment, the rectangle is usually the main one. Rectangular stainless steel air duct needs to be connected and processed before use, and the commonly used connection metho...

AI Technical Summary

Problems solved by technology

[0003] The rectangular stainless steel air duct needs to be connected and processed before use. The commonly used connection methods mainly include angle iron flange connection and common plate connection. The advantages of the former are high strength, not easy to deform, easy to disassemble and easy to connect with equipment. It is high cost, the air tightness of the overall air duct is relatively poor, the gravity of the air duct itself is large, and the connection is not easy to keep warm. The latter has the advantages of high production and processing efficiency, relatively low gravity of the air duct itself and good overall air tightness. The advantages and disadvantages are that the strength is relatively low and it is easy to deform. Secondly, the stainless steel air duct can also be connected by welding. The welding process has the advantages of good air tightness, high connection strength and low air duct weight, but its disadvantages are It is not convenient for maintenance and is affected by the thickness of the air duct during the welding process, which makes welding more difficult and less efficient, thus reducing the frequency of use of this connection method

[0004] During the connection process of the rectangular stainless steel air duct, the corresponding connection processing method will be selected according to the use environment of the air duct. For the environment with high air tightness and connection strength and low anti-gravity ability, welding processing or welding is usually selected. The processing method is combined with the angle iron flange connection. However, when the existing welding processing equipment welds the rectangular stainless steel air duct, because the air duct is generally thin, it is difficult to accurately butt and fix it, which increases the difficulty of welding. , while reducing the efficiency of welding, and during the welding process, the air duct is prone to deformation due to uneven force, which will further increase the difficulty of welding and reduce the quality of welding
