Dimensioning method for sheet metal parts?
This type of parts under the material size calculation is divided into two parts: one for the more complex sheet metal parts (this part of the study is not for the time being, because the sheet metal parts need to be analyzed separately to unfold); the other part of a simple sheet metal sample parts, generally take the size of its outer contour.
1) linear sample material sheet metal parts material table. Analysis: Figure l shows two kinds of sheet metal parts for irregular trapezoid, the production of this type of material table is generally considered according to the triangle or rectangle. Material table: 98 * 110 triangular sample; 135 * 175 sample.

2)Arc sample plate material plate material table production. Figure 2 shows a piece of sample material with an arc, the maximum size of the material in the direction of the arc should be added 5-10 mm shear allowance. Calculation: (omitted), material table: 605 * 115.
The sample material shown in the figure above, considering its material is longer, the next piece of material is not easy to cut material, so the next two pieces of material production. In addition, in the width of 5-10mm allowance. Material table: 235*1117(2).
Information to expand:1, sheet metal is a sheet metal (usually below 6mm) for a comprehensive cold working process, including shearing, punching / cutting / composite, folding, welding, riveting, splicing, molding (such as car body) and so on. Its distinctive feature is the consistent thickness of the same part. The products processed through the sheet metal process are called sheet metal parts. Sheet metal parts referred to by different industries are generally different, and are mostly used for grouping when called.
2, a foreign professional journals on a definition of sheet metal can be defined as: sheet metal is for sheet metal (usually below 6mm) a comprehensive cold process, including shearing, punching/cutting/compounding, folding, welding, riveting, splicing, molding (such as car body) and so on. Its distinguishing feature is the same part thickness is consistent.
3, sheet metal parts with light weight, high strength, conductive (able to be used for electromagnetic shielding), low cost, large-scale mass production performance, etc., in the field of electronic and electrical appliances, communications, automotive industry, medical equipment and other fields have been widely used, for example, in the computer chassis, cell phones, MP3, the sheet metal parts is an essential component.
