Sheet metal processing is closely related to our lives, and almost all manufacturing industries are inseparable from sheet metal processing. Sheet metal shell processing products that meet these material requirements can better meet the needs of various sheet metal processing to produce high-quality sheet metal shell parts.
The material requirements for sheet metal shell processing are as follows:
- Good solderability
Many sheet metal shells are welded together by spot welding, oxygen welding, arc welding, or gas shielded welding, so the processing materials of sheet metal shells are required to have good welding performance.
- Good cold plasticity
It must have the ability to generate permanent deformation without being damaged under the action of external force. For cold-worked parts, sheet metal shell processing materials must have good cold plasticity, such as stamping parts for automobile parts. Hot-worked parts must have good thermoplasticity, such as hot forging spring steel plates, hot rivets, etc.
- Good chemical stability
Some sheet metal shells primarily work in the open air, often in contact with water and steam, and at higher temperatures and corrosive gases. This requires that the sheet metal shell processing materials have good chemical stability, which requires corrosion resistance at room temperature and strong rust resistance, and no corrosion or deformation under high temperature or sun exposure.
- Good dimensional accuracy and intrinsic quality of the plate:
The dimensional accuracy and intrinsic quality of sheet metal shell processing materials significantly impact sheet metal processing, especially for molded parts. Therefore, the material for sheet metal shell processing should pay attention to the selection of materials with good dimensional accuracy and intrinsic quality of the plate so that the sheet metal shell processed products can better meet users’ needs.
What aspects should be paid attention to in the design of sheet metal shell parts?
1. The expansion method of the sheet metal shell design must be pretty reasonable, and attention should be paid to saving materials and their processability.
2. When designing the sheet metal shell, attention should be paid to unique angles. The inner radius of the bending angle (generally R=0/5) should be unfolded according to the trial folding.
3. The sheet metal shell design should have good usability and necessary protective facilities to make the equipment easy to operate, install and maintain. It is safe and reliable to use.
4. The design of the sheet metal shell should meet the requirements of standardization, standardization, and serialization and pursue a beautiful appearance, applicability, and color coordination based on ensuring the performance of the equipment.
5. When designing the sheet metal shell, its structure and layout should be reasonably designed, the overall design should be ergonomic, the human-computer interaction design should be humanized, and various safety hazards should be fully considered to ensure safe reliable, convenient and comfortable operation of the equipment.
6. The sheet metal shell mainly plays the role of fixing and protecting the internal structure of the equipment. When designing, the sheet metal shell should be designed according to the customer’s drawings or specific specifications and dimensions, and meet the requirements of the internal structure design, to achieve a low cost and a beautiful appearance.
7. In the design of sheet metal shells, the influence of material technology, processing procedures, production costs, and other factors should be considered so that the design meets the process requirements, the structure assembly is simple, and the product is easy to debug package and transport, and ensure the feasibility and practicability of the design drawings.
To sum up, these are some aspects that should be paid attention to in the design of sheet metal shells. It is worth noting that the unique forming process of sheet metal is not suitable for complex shapes. Therefore, it is necessary to break through the traditional box shape and facilitate manufacturing and processing in the design of sheet metal shells. It is not suitable to do more rich surface changes. It is more suitable to do more surface processing, reduce the difficulty of production and manufacture, ensure the feasibility of the design scheme, and make the equipment simple and beautiful, which is in line with people’s aesthetics.
