设计钣金件的时候图画展开时候要注意什么

1.展开要合理,尽量的减少绘画的难度和表明的参数,使整个设计画面要简洁明了,另外还要减少不必要的工序以及加工的方便性,考虑实际加工工艺要合理的安排加工工序。

2.合理的选择间隙及包边方式

间隙以及一些边长的计算方式要标注准确,但是要注意不同的板材有着不同的测量标准,千万不要把计算的方法应用于不同板材的长边计算之中。

3.必须合理的考虑公差

在实际的设计和安装过程中,多多少少都会出现一些误差,这些都是不可避免的正常情况,把公差计算出来就能大体的知道该使用多达的尺寸了,留有一定的间隙或者长度,是我们经常会用到避免的误差方法。

4. 抽牙,压铆,冲凸,撕裂等位置方向必须明确,画出剖面图。

5. 对于图面上不同孔径的孔为了加以区别应在图面上用字母分别标识吗,不同孔径采用不同的字母。

1. should be reasonable, as far as possible to reduce the difficulty of painting and the parameters to be shown, so that the whole design picture should be concise and clear. In addition, the unnecessary process and the convenience of processing should be reduced, and the processing procedure should be rationally arranged in consideration of the actual processing technology.

2. reasonable choice of gap and way of edge

The calculation method of clearance and some side length should be marked accurately, but it should be noted that different plates have different measurement standards. Do not apply the calculation method to the long side calculation of different plates.

3. the tolerances must be considered reasonably

In the actual design and installation process, more or less will appear some errors, these are inevitable normal conditions, the tolerance calculation can be generally known as to the size of the use, leaving a certain gap or length, is the error we often use to avoid the error method.

4. draw the teeth, press riveting, punch, tear, etc. the direction of position must be clear, draw the profile.

5. in order to distinguish the holes with different apertures on the figure surface, we should use the letters to identify them on the drawing surface respectively, with different letters in different apertures.
