1. Determine the type and overall dimensions of the chassis

机箱类型是在总体布局过程中，根据不同的产品应用需求，制定各种不同方案，经过讨论分析和比较而确定是挂墙式、桌面式、还是上架式的。机箱尺寸是按机箱内元器件的大小确定初步尺寸，然后根据这个尺寸选用标准尺寸；也可选择定标准的外形尺寸，再进行箱内的元器件布局分配。

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、面板设计、机箱内元器件的排列布局

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

面板的尺寸是在机箱类型、尺寸确定后定下的，而面板上各种操纵和显示装置的选择和布局，应该根据电原理图的要求、人机工程、造型、通风等因素综合考虑。机箱内部元器件的排列是根据电原理图，主要元、器件的外形尺寸及相互关系，并考虑通风、减振、屏蔽及走线的方便美观程度等来确定的。

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、详细研讨产品的技术指标

3. Detailed discussion of product technical indicators

产品的技术指标是设计、制造与使用的一个依据，亦是检验产品质量的客观标准，为了正确的进行机箱结构设计，应深入实际，详细研讨产品的各项技术指标，了解众多地区同类产品或相近类型产品的结构与使用情况，然后再确定结构的形式。

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、确定机箱零部件结构形式

4. Determine the structural form of chassis components

图纸是工业的语言，再好的设计，也需用它表达出来，一套清晰完整的图纸是一个好的产品的前提和确定。

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.

钣金加工中冲压是较常用的方法，冲压技术大体的分为分别工序和成形工序两大类。

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、成形工序是使冲压坯料在不损坏的条件下发生塑性变形，并转化成所需求的制品形状，也应达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、分别工序是在冲压过程中使冲压件与坯料沿相应的轮廓线互相分别，一同冲压件分别断面的质量也要达到相应的需求，这些需求都是前期客户的需求所选择的。

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.

钣金加工的小窍门你知道吗？

Do you know the tips for sheet metal processing?

1、钣金加工时为避免崩碎切屑伤人，钣金加工应在适当的位置安装透明挡板。

1. To avoid crushing and injuring people during sheet metal processing, transparent baffles should be installed at appropriate positions during sheet metal processing.

2、切削时发生的带状切屑，螺旋状长切屑，应运用钩子及时去掉，禁止用手拉。

2. Strip shaped chips and spiral shaped long chips that occur during cutting should be removed in a timely manner using hooks and cannot be pulled by hand.

3、保持机床、工具、作业地整洁，做好交接班。下班打扫作业地，应关闭电源，将各种走刀手柄放到稳定处。

3. Keep the machine tools, tools, and work area clean and tidy, and do a good job of handover. When cleaning the work area after work, the power should be turned off and various tool handling handles should be placed in a stable position.

4、车床主轴上装卸卡盘，相应要停机后进行，不行运用电动机的力气来取下卡盘。

4. The loading and unloading of the chuck on the lathe spindle should be carried out after the corresponding shutdown, and the force of the electric motor should not be used to remove the chuck.

5、需要用纱布打磨工件外表时，应把刀具移到稳定位置，并留意不要让手和衣服触摸工件外表。磨内孔时，不可以用手指支撑纱布，应使用木棍替代。

5. When it is necessary to use gauze to polish the surface of the workpiece, the cutting tool should be moved to a stable position and attention should be paid not to let hands and clothes touch the surface of the workpiece. When grinding the inner hole, it is not allowed to use fingers to support the gauze, and a wooden stick should be used instead.

6、车削形状不规则的工件时，应装平衡块，在试转平衡后再切削。

6. When turning irregularly shaped workpieces, a balance block should be installed and cut after trial running for balance.

7、夹持工件的卡盘，拨盘，鸡心夹的凸出部分需要使用防护罩，避免绞住衣服及身体的其他部位。如无防护罩，操作时应注意保持相应的间隔。

7. The protruding parts of the chuck, dial, and chicken heart clamp that hold the workpiece need to use protective covers to avoid twisting clothes and other parts of the body. If there is no protective cover, pay attention to maintaining corresponding intervals during operation.

8、严禁把工具，夹具或工件放在车床床身上和主轴变速箱上。作业时要思想会集。禁止疲惫操作、聊天操作、多人操作、酒后操作、吸烟操作。

8. It is strictly prohibited to place tools, fixtures, or workpieces on the lathe bed and spindle gearbox. When doing homework, gather your thoughts. Prohibit fatigue operation, chat operation, multi person operation, drunk operation, and smoking operation.

9、刀具夹装要，刀头伸出部分不要超出刀体高度的1.5倍，刀具下垫片的形状和尺度应与刀体形状，尺度相一致，垫片应尽可能少而平。

9. When clamping the tool, the protruding part of the tool head should not exceed 1.5 times the height of the tool body. The shape and scale of the gasket under the tool should be consistent with the shape and scale of the tool body, and the gasket should be as small and flat as possible.

10、除车床上装有作业中能自动测量的量具外，均应停车并将刀架移动到安多角度后再测量工件。

10. Except for measuring tools that can be automatically measured during operation, the lathe should be stopped and the tool holder moved to an angle of Anduo before measuring the workpiece.
