鈑金機箱是指利用特殊的鈑金材料制作而成的機箱，在鈑金機箱外殼設計中，除了要發揮其特點優勢，還要避免鈑金加工工藝對其造型的不利影響，應注意以下幾個事項。

Sheet metal case refers to the case made of special sheet metal materials. In the design of sheet metal case shell, in addition to giving full play to its characteristics and advantages, it is also necessary to avoid the adverse impact of sheet metal processing technology on its shape. The following matters should be noted.

1、鈑金機箱外殼設計的展開方式一定要相當合理，要注意節省材料以及其加工性。

1. The unfolding method of the shell design of the sheet metal chassis must be quite reasonable, and attention should be paid to saving materials and its processability.

2、選擇間隙及包邊方式應該謹慎合理，T=2.0以下，間隙為0.2;T=2-3之間，間隙為0.5;包邊方式應該采用長邊包短邊的方式(即門板類)。

2. The clearance and edging method shall be selected carefully and reasonably. The clearance is 0.2 when t = 2.0 or less; T = 2-3, the clearance is 0.5; The edge wrapping method shall adopt the method of wrapping the long side with the short side (i.e. door panel).

3、公差外形尺寸：負責走到底，正差走一半;孔形尺寸：走差走到底，負差走一半。

3. Tolerance outline dimension: responsible for going to the end, and half of the positive difference; Hole size: the deviation goes to the end, and the negative difference goes half.

4、毛刺方向。

4. Burr direction.

5、撕裂、壓鉚、抽牙、沖凸點(包)等位置方向，畫出剖視圖。

5. Draw a cross-sectional view of the position and direction of tearing, riveting, tooth extraction, punch bump (package).

6、核對其材質，板的厚度，以及板厚的公差。

6. Check the material, plate thickness and plate thickness tolerance.

7、注意特殊的角度，折彎角內半徑(一般R=0/5)要試折而定將其進行展開。

7. Pay attention to the special angle. The inner radius of the bending angle (generally r = 0 / 5) shall be expanded according to the trial bending.

8、有易出錯(比如相似不對稱的地方)的地方應該提出。

8. Places prone to errors (such as similar and asymmetrical places) should be highlighted.

9、尺寸較多的地方要加上放大之后的圖片。

9. Where the size is large, the enlarged picture shall be added.

10、需要進行噴涂保護的地方應該表示出來。

10. The places requiring spraying protection shall be indicated.

當然，因鈑金的獨特成型工藝導致其不宜有復雜的造型，所以在鈑金機箱外殼設計上既要突破傳統的方框造型，又要便于制造加工，不宜多做豐碩的曲面變化，比較適合多做表面工藝的處理，降低出產制造的難度，確保設計方案可行性的同時，使設備造型簡潔美觀，符合人們審美。更多相關內容就來我們網站http://www.metferro.com咨詢了解吧。

Of course, due to the unique forming process of sheet metal, it is not suitable to have complex shapes. Therefore, in the design of sheet metal chassis shell, it is not only necessary to break through the traditional box shape, but also convenient for manufacturing and processing. It is not suitable to do more surface changes. It is more suitable to do more surface processing, reduce the difficulty of production and manufacturing, ensure the feasibility of the design scheme, and make the equipment shape simple and beautiful, and meet people's aesthetics.
