Installation process of large tuyere blades

Abstract

The invention relates to an installation process of large tuyere blades. The installation process comprises the steps that S1, a blade positioning device is established and comprises a positioning structure, an alignment structure and a tie bar structure; S2, multiple blade bodies are sequentially and correspondingly inserted into notches of multiple positioning seats, so that the distribution direction of the multiple blade bodies is consistent with the extension direction of the long axis of the positioning seats; S3, tie bar rods are inserted into aluminum pipes, and then the aluminum pipes inserted with the tie bar rods penetrate through penetrating holes of the multiple blade bodies; S4, under the contraction action of second driving cylinders, limiting baffles enable the tie bar rods to be embedded in limiting grooves of the limiting baffles; S5, pulling assemblies are started, and the tie bar rods are pulled out of the aluminum pipes under the horizontal pulling force of the corresponding pulling assemblies; and S6, the installed tuyere blades are subjected to integral discharging from the positioning seats. The installation process has the following advantages that the mounting precision and the mounting efficiency are improved, welding stress and welding defects caused by traditional welding fixation are avoided, and the connecting stability of the blade body is guaranteed.

Description

Technical field: [0001] The invention relates to the field of tuyere blades, in particular to an installation process for large-scale tuyere blades. Background technique: [0002] As people's demand for comfort is getting higher and higher, the comfort of the air conditioning system has become the primary problem to be solved by the air conditioner, and the air outlet blade is one of the most important structures in the air conditioning system. The large air outlet blade consists of multiple blades distributed at equal intervals. Multiple blade bodies are integrally connected through a plurality of aluminum tubes vertically penetrating the blade body. Usually, there are two aluminum tubes, and the blade body has a perforation for the vertical insertion of the aluminum tube. The perforation of multiple blade bodies, so in order to facilitate the insertion of the aluminum tube, the inner diameter of the perforation of the blade body is usually larger than the outer diameter of...

[0002] As people's demand for comfort is getting higher and higher, the comfort of the air conditioning system has become the primary problem to be solved by the air conditioner, and the air outlet blade is one of the most important structures in the air conditioning system. The large air outlet blade consists of multiple blades distributed at equal intervals. Multiple blade bodies are integrally connected through a plurality of aluminum tubes vertically penetrating the blade body. Usually, there are two aluminum tubes, and the blade body has a perforation for the vertical insertion of the aluminum tube. The perforation of multiple blade bodies, so in order to facilitate the insertion of the aluminum tube, the inner diameter of the perforation of the blade body is usually larger than the outer diameter of the aluminum tube, and then the blade body and the aluminum tube are fixed by welding. The gap between the joints makes the blade body after welding unable to guarantee a certain degree of correspondence, and because the thickness of the blade body is thin and the wall thickness of the aluminum tube is small, the welding stress concentration at the joint is very easy to occur during welding, and the welding joint is deformed and other defects, the welding quality of the aluminum tube and the blade body is poor during perforation welding, which affects the aesthetics of the entire tuyere blade
