精密机械零部件加工工艺性的基本要求

2018-05-31 21:50:51 腾讯分分彩开奖直播 阅读

精密机械零部件加工在进行设计的过程中不仅要满足其使用要求,即具备其所要求的工作的能力,在进行操作的过程中同时还应当满足生产要求,精密机械零部件加工在进行设计的过程中便于加工而加工费用很低,这样的零件在一定程度上就会被称为具有良好的工艺性。

精密机械零部件加工工艺性的基本要求

1. 毛坯在进行选择的过程中,需要采用其合理额机械制造中的毛坯制备方法,在进行操作时会直接利用其型材、铸造、锻造、焊接以及冲压等方法,在进行使用时其毛坯的选择和具体的生产技术条件是有关的,一般情况下取决于生产批量以及才能性能和加工可能性等。

2. 精密机械零部件加工的结构在进行设计的过程中是非常的简单的,在进行操作时主要是采用最简单的表面以及组合,在一定程度上同时还应当尽量使用加工的表面的数目最少和加工面积最小。

3. 精密机械零部件加工规定适当的制造精度和表面粗糙度的零件的急啊佛那个费用会随着其精度的提高而增加,在进行操作时在精度较高的情况下,这样的增加极为显著,因此,在没有充分根据时,不应当追求高的精度。同理,零件的表面粗糙度也应当根据配合表面的实际需要,作出适当的规定。

4. 精密机械零部件加工在一定程度时其设计出工艺性良好的零件,在进行设计的过程中就必须要和工艺技术员工相结合并善于向他们学习,此外,在金属工艺学课程和手册中也都提供了一些有关工艺性的基本知识,可供参考。

精密机械零部件加工的表面粗糙度在一定程度上可以有效的反应其零件表面的微观几何形状的误差的一个非常重要的技术指标,在进行使用时这是检验零件表面质量的主要依据。

In the process of design, precision mechanical parts should not only meet the requirements of their use, that is, the ability to work, and also to meet the production requirements during the process of operation. The processing costs of precision mechanical parts are easy to be added in the process of design and the cost of processing is very low. To a certain extent, it will be called good manufacturability.

Basic requirements for processing technology of precision machinery parts

1. in the process of selection, the blank preparation method in reasonable mechanical manufacturing should be adopted. In the process of operation, the blanks, casting, forging, welding and stamping are used directly. The selection of blank and the specific technical conditions are related to the process. In terms of production lot size, capability and processing possibility.

2. the structure of precision mechanical parts processing is very simple in the process of design. In the operation, the simplest surface and combination are mainly used. At the same time, the minimum number of machined surfaces and the minimum processing area should be used to a certain extent.

3. the precision and surface roughness of parts of precision machinery parts processing will be increased with the increase of its precision. In the case of high precision operation, this increase is very significant. Therefore, high precision should not be pursued when there is no sufficient basis. Similarly, the surface roughness of parts should be made according to the actual requirements of the mating surface.

4. in a certain degree, the machining of precision machinery parts is designed for good technological parts. In the process of designing, it is necessary to combine with the technical staff and learn from them. In addition, some basic knowledge about technology is provided in the course and manual of metal technology, which can be used for reference.

The surface roughness of precision mechanical parts is a very important technical indicator to some extent, which can effectively reflect the micro geometry of the surface of the parts. It is the main basis for the inspection of the surface quality of the parts.
