The processing technology of PLC electrical cabinet sheet metal shell has a crucial impact on its final quality.
First of all, in terms of the cutting process, if the accuracy is not accurate enough, it may cause deviations in the size of the plate, affecting the assembly accuracy and sealing of the shell. Rough cutting edges may also contain burrs and sharp edges, which not only affects the appearance, but may also cause scratches during installation and use, and even damage internal electrical components.
The quality of the bending process is directly related to the structural strength and stability of the shell. Incorrect bending angles and radii will deform the structure of the shell and reduce its load-bearing capacity and impact resistance. Moreover, uneven bending may lead to uneven surface of the shell, affecting the overall appearance and protective performance.
The impact of the welding process on quality is equally significant. The quality of the weld directly determines the sealing and strength of the shell. If the welding is not firm, the weld may crack during use, causing the shell to lose its protective effect and even endangering the normal operation of the electrical cabinet. At the same time, if the residual stress generated during the welding process is not effectively eliminated, it may cause the shell to deform and affect the dimensional accuracy.
Surface treatment process is also one of the key links. Good surface treatment can improve the corrosion resistance and wear resistance of the shell and extend its service life. For example, uneven painting or insufficient coating thickness can easily lead to rust and corrosion of the casing. The use of high-quality surface treatment processes, such as electroplating, phosphating, etc., can enhance the protective performance of the shell.
In addition, the accuracy of the punching and tapping process will affect the position and dimensional accuracy of the mounting holes and threaded holes on the housing, which in turn affects the installation and fixing of electrical components. If the punching deviation or tapping is irregular, it may cause installation difficulties, loose components, and even affect the reliability of electrical connections.
As a practical example, if there is a problem with the bending process during the processing of the PLC electrical cabinet sheet metal shell, resulting in inconsistent bending angles of the side plates of the shell, gaps will appear during assembly and good quality cannot be achieved. protective effect. Similarly, if the welding process is not up to standard and pores or cracks appear at the weld, in harsh working environments, moisture and corrosive substances will enter the interior of the electrical cabinet through the weld, causing electrical failure.
To sum up, the processing technology of PLC electrical cabinet sheet metal shell covers many links from cutting, bending, welding to surface treatment. The process level of each link directly affects the dimensional accuracy, structural strength and protection of the shell. Performance and appearance quality. Therefore, during the production process, each processing process must be strictly controlled to ensure that the quality of the shell meets the requirements and provide reliable guarantee for the normal operation of the PLC electrical cabinet.
