Because different electrical equipment components need to be installed inside the sheet metal chassis, there are bound to be many cables. Therefore, the wiring methods in the same chassis should be consistent, which is convenient for installation and provides convenient conditions for future reconstruction, upgrades and daily maintenance. For the chassis core network equipment, internal network access equipment, management network access equipment, etc. are different.
The modeling design of industrial sheet metal equipment is restricted by sheet metal processing methods. At present, the common sheet metal material processing methods on the market mainly include stamping forming, bending forming, cutting, welding and so on. Sheet metal materials are mostly sheet-like. Generally speaking, in the design of sheet metal equipment, designers are more concerned with the one-way arc of the product, and seldom consider the two-way arc. Because the shape of the two-way arc requires a stamping die, this will lead to increased costs.
It should be noted that when designing sheet metal, standard curved surfaces should be used as much as possible. Because the data is not easy to control during bending, cutting cylinder welding is generally adopted. As far as welding is concerned, designers cannot think of this welding for multiple purposes. Some designers like to cut a bevel on a single arc surface and use a straight surface to seal the cover. From this point of view, the welding accuracy is not easy to control, and the design is very unsightly.
