鈑金機(jī)箱是指利用特殊的鈑金材料制作而成的機(jī)箱，在鈑金機(jī)箱外殼設(shè)計(jì)中，除了要發(fā)揮其特點(diǎn)優(yōu)勢(shì)，還要避免鈑金加工工藝對(duì)其造型的不利影響，應(yīng)注意以下幾個(gè)事項(xiàng)。

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(jī)箱外殼設(shè)計(jì)的展開(kāi)方式一定要相當(dāng)合理，要注意節(jié)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(yīng)該謹(jǐn)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(yīng)該采用長(zhǎng)邊包短邊的方式(即門(mén)板類(lèi))。

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(fù)責(zé)走到底，正差走一半;孔形尺寸：走差走到底，負(fù)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(diǎn)(包)等位置方向，畫(huà)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(duì)其材質(zhì)，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(nèi)半徑(一般R=0/5)要試折而定將其進(jìn)行展開(kāi)。

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(cuò)(比如相似不對(duì)稱(chēng)的地方)的地方應(yīng)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(jìn)行噴涂保護(hù)的地方應(yīng)該表示出來(lái)。

10. The places requiring spraying protection shall be indicated.

當(dāng)然，因鈑金的獨(dú)特成型工藝導(dǎo)致其不宜有復(fù)雜的造型，所以在鈑金機(jī)箱外殼設(shè)計(jì)上既要突破傳統(tǒng)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(chǎn)制造的難度，確保設(shè)計(jì)方案可行性的同時(shí)，使設(shè)備造型簡(jiǎn)潔美觀，符合人們審美。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://www.ebook5.cn咨詢(xún)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.
