There are two kinds of production and processing profiles commonly used in the processing of chassis shell sheet metal, namely, steel profiles and aluminum profiles. Although the steel column frame machine is fully enclosed and has large bearing capacity, it is difficult to clean the inner cavity, and the corrosion problem of the inner cavity is not easy to deal with. The chassis is the chassis of large, medium and small electronic products, which is a box type structure. In the structural design scheme of the chassis shell sheet metal processing, in terms of its structural process performance, the following aspects should be paid attention to:
1. the convenience of installation and wiring shall be considered.
2. for parts of arc welding and gas cutting, the surface coating shall not be carried out before electric welding.
3. during electric welding of parts, the thickness of raw materials and the length of welding shall ensure small deformation after welding.
4. make the structure as simple as possible, and the lower the parts, the higher the parts, under the condition of meeting the requirements for the application of sheet metal processing of automobile chassis shell.
5. the profile (prefabricated component) reaches the compressive strength Under the condition of bending rigidity and good-looking, it is necessary to make the cross-section look simple and reduce the production and processing process.
6. standardized and normative parts and specification series products shall be selected as far as possible to facilitate the selection of universal work clothes during the whole process of metal plate processing of automobile chassis shell, and try to avoid the total number of non-standard parts to make its structure simple.
In addition, the design, production and processing of sheet metal casings are complex. When manufacturing, it must use hand-made or special tools to convert some metal plates into the shapes and specifications required by consumers. In this link, some parts must be welded to achieve the overall design goal. The material of the gold box is carefully selected, and it is common to select these relatively reliable raw materials.
The applicable sheet metal parts of sheet metal manufacturing enterprises are mainly realized according to the work of fiber laser cutting, metal bonding, plasma cutting machine, high-precision electric welding, etc. it is not difficult to see how complicated the production process is. That will not only ensure that the external structure of the server cabinet of the sheet metal chassis is reasonable and firm, but also effectively meet the needs of customers, and promote the market sales of the sheet metal chassis to become stronger.
Shandong rapid prototyping manufacturers believe that this is precisely because the role of metal plate box is very critical, so its design and production are more stringent, so as to ensure that the characteristics of metal plate box can be fully used.
