1. Determine the type and overall dimensions of the chassis

機箱類型是在總體布局過程中，根據(jù)不同的產(chǎn)品應(yīng)用需求，制定各種不同方案，經(jīng)過討論分析和比較而確定是掛墻式、桌面式、還是上架式的。機箱尺寸是按機箱內(nèi)元器件的大小確定初步尺寸，然后根據(jù)這個尺寸選用標(biāo)準(zhǔn)尺寸；也可選擇定標(biāo)準(zhǔn)的外形尺寸，再進(jìn)行箱內(nèi)的元器件布局分配。

The type of chassis is determined through discussion, analysis, and comparison during the overall layout process, based on different product application requirements, to determine whether it is wall mounted, desktop mounted, or shelving. The size of the chassis is determined based on the size of the components inside the chassis, and then standard dimensions are selected based on this size; You can also choose to set standard external dimensions and then allocate the layout of components inside the box.

2、面板設(shè)計、機箱內(nèi)元器件的排列布局

2. Panel design, arrangement and layout of components within the chassis

面板的尺寸是在機箱類型、尺寸確定后定下的，而面板上各種操縱和顯示裝置的選擇和布局，應(yīng)該根據(jù)電原理圖的要求、人機工程、造型、通風(fēng)等因素綜合考慮。機箱內(nèi)部元器件的排列是根據(jù)電原理圖，主要元、器件的外形尺寸及相互關(guān)系，并考慮通風(fēng)、減振、屏蔽及走線的方便美觀程度等來確定的。

The size of the panel is determined after the type and size of the chassis are determined, and the selection and layout of various control and display devices on the panel should be comprehensively considered based on the requirements of the electrical schematic, ergonomics, styling, ventilation, and other factors. The arrangement of components inside the chassis is determined based on the electrical schematic diagram, the external dimensions and interrelationships of the main components and components, and considering the convenience and aesthetics of ventilation, vibration reduction, shielding, and wiring.

3、詳細(xì)研討產(chǎn)品的技術(shù)指標(biāo)

3. Detailed discussion of product technical indicators

產(chǎn)品的技術(shù)指標(biāo)是設(shè)計、制造與使用的一個依據(jù)，亦是檢驗產(chǎn)品質(zhì)量的客觀標(biāo)準(zhǔn)，為了正確的進(jìn)行機箱結(jié)構(gòu)設(shè)計，應(yīng)深入實際，詳細(xì)研討產(chǎn)品的各項技術(shù)指標(biāo)，了解眾多地區(qū)同類產(chǎn)品或相近類型產(chǎn)品的結(jié)構(gòu)與使用情況，然后再確定結(jié)構(gòu)的形式。

The technical indicators of a product are a basis for design, manufacturing, and use, as well as an objective standard for inspecting product quality. In order to correctly design the chassis structure, it is necessary to delve into practical situations, discuss in detail the various technical indicators of the product, understand the structure and usage of similar products or similar types of products in many regions, and then determine the form of the structure.

4、確定機箱零部件結(jié)構(gòu)形式

4. Determine the structural form of chassis components

圖紙是工業(yè)的語言，再好的設(shè)計，也需用它表達(dá)出來，一套清晰完整的圖紙是一個好的產(chǎn)品的前提和確定。

Drawing is the language of industry, and even a good design needs to be expressed in it. A clear and complete set of drawings is the premise and determination of a good product.

鈑金加工中沖壓是較常用的方法，沖壓技術(shù)大體的分為分別工序和成形工序兩大類。

Stamping is a commonly used method in sheet metal processing, and stamping technology is generally divided into two categories: separate processes and forming processes.

1、成形工序是使沖壓坯料在不損壞的條件下發(fā)生塑性變形，并轉(zhuǎn)化成所需求的制品形狀，也應(yīng)達(dá)到尺度等方面的需求。

1. The forming process is to make the stamping blank undergo plastic deformation without damage, and transform it into the desired product shape, which should also meet the requirements of scale and other aspects.

2、分別工序是在沖壓過程中使沖壓件與坯料沿相應(yīng)的輪廓線互相分別，一同沖壓件分別斷面的質(zhì)量也要達(dá)到相應(yīng)的需求，這些需求都是前期客戶的需求所選擇的。

2. The separate process is to separate the stamped parts and blanks along the corresponding contour lines during the stamping process, and the quality of the separate sections of the stamped parts must also meet the corresponding requirements, which are selected by the customer's needs in the early stage.

鈑金加工的小竅門你知道嗎？

Do you know the tips for sheet metal processing?

1、鈑金加工時為避免崩碎切屑傷人，鈑金加工應(yīng)在適當(dāng)?shù)奈恢冒惭b透明擋板。
