What is the definition of mechanical parts? What are the mechanical parts? What are the corresponding casting and forging parts?

Hangzhou Guangyu mould Co., Ltd. answers one by one

Mechanical parts are defined as:

1.Part -- a single component that cannot be split.

2. Component -- a combination of parts that realize a certain action (or function). An assembly can be a single part or a combination of multiple parts. In this assembly, one part is the main part, which realizes the given action (or function), while other parts only play auxiliary roles such as connection, fastening and guidance.

3. Parts and components - under normal circumstances, all parts and components except the rack are collectively referred to as parts and components. Of course, the rack is also a component.

As for cast parts and forged parts, it is the classification of manufacturing methods of parts. Different materials and manufacturing methods make parts have different mechanical properties. Not the same concept as components.

How to draw the drawings of mechanical parts

As long as you know CAD, it's easy to draw three drawings on a piece of paper for a mechanical part: the front view (the drawing seen from the front of the part), the front view (the drawing seen from the right above the part), and the left view (the drawing seen from the right left of the part). Generally, simple parts can be expressed clearly by drawing these three drawings, such as gear shaft. For drawings with complex structures, cross-sectional views and partial enlarged drawings should also be drawn, that is, a certain part of a part should be cut to express its internal structure and dimensions clearly, such as screw holes, gear boxes, gears, etc. It's not enough to know so much. If you want to know how to draw in detail, you should also look at the mechanical parts drawings. In fact, most of the assembly drawings are used in practice. There are many details to pay attention to. Practice more and read the books.

In addition, mechanical parts also have their own standardized production. This is because the United States has standardized the mechanical parts, such as the length and diameter of screws. A series of parts have been standardized, so that it is very easy to repair the machinery in case of failure. This measure is similar to the Chinese Qin Shihuang's unified writing, language and weights and measures!
