Characteristics and advantages of sheet metal manufacturing design?

Sheet metal equipment is widely used in our lives, such as common computer cases, power cabinets, self-service terminals, CNC machine tools, etc. However, due to the special properties of sheet metal materials, sheet metal manufacturing technology has a great impact on design. Therefore, in the sheet metal manufacturing design process, the influence of material technology should be fully considered, highlighting its characteristics and advantages. So Sheet metal manufacturing What are the characteristics and advantages of design?

First of all, we need to know what sheet metal is? Its significant characteristic is that the thickness of the same part is consistent. According to the definition, sheet metal is the cold processing process of metal sheet materials, including shearing, punching/cutting/compositing, folding, riveting, splicing, forming (such as car bodies), etc. There are two main types of surface treatment: powder coating (powder spraying) and painting. Large parts are generally sprayed with plastic, and small parts can be painted. This is determined by the characteristics of the process.

Compared with other cutting technologies, sheet metal cutting technology has the advantages of high speed, high precision, strong adaptability, fine cutting welds, small heat affected zone (small deformation), good end face quality, no noise, and weld joint properties close to the base material. Moreover, only simple fixtures are needed for processing, no molds are needed, and it can replace the processing method of complex mold punching, which greatly shortens the production cycle and reduces the production cost. Let's talk about the characteristics of sheet metal manufacturing design first.

Sheet metal manufacturing It needs to meet its process characteristics, and generally should have the following characteristics.

1. Cost: Reasonableness The first consideration is cost. The positioning of the product as high, medium, and low-end must be clear, which involves material selection, process layout, surface treatment, decoration, etc. This makes the cost "reasonable";

2. Shape. Due to its special processing technology, the shape design should be adapted to minimize curve design;

3. Material selection, fully consider the application environment and other factors, reasonably select raw materials and surface treatment processes;

4. Structure: Sheet metal focuses on rigidity rather than strength, and the cross-sectional design of the bending part should be reasonable;

5. Process: That is, the manufacturability of the product (needs to be exercised on the next production line), such as avoiding bending positions, the design of weld points and welds should not affect post-weld deformation, the number, size and allowance of punching reasonably affect flatness, electroplated parts cannot be pressed, and the assembly and disassembly sequence of workpieces cannot interfere with each other.

It should be noted that, Sheet metal manufacturing The design mainly plays three roles. First, the load-bearing part of the equipment needs to withstand the gravity of the main body (including the force generated during its movement); second, the moving connectors need to operate in a coordinated manner according to the requirements of the application software; third, the main external frame, which needs to reflect the characteristics of flexible hardware. Therefore, it is necessary to combine materials science, mechanics, mechanical engineering, industrial design and other disciplines for comprehensive design to meet its functional and appearance process requirements.
