机架制造的主要工艺措施完成钣金加工要求

机架制造过程中,主要的工艺流程包括有工件装卡找正、基准面的加工、封闭槽形的加工以及孔底大型过渡圆R弧的加工等。其中在装卡找正环节中,主要是考虑机架制造时放置的问题。

    然后是对机架制造部件基准面的加工。通常基准面主要包括有:安装基面,地脚面面。尤其是安装基面是最重要的基准面,采用4号角铣头装刀盘,分半精,精加工两次铣出基准面及安装基面,并保证两基准面的相互垂直度,同时,控制尺寸665,并实测该尺寸供另一机架加工时配对使用。

    接下来是完成封闭槽形的加工。比如在某一机架制造过程中,其封闭槽形其底部带有过渡圆弧R30~R50mm,在转角处形成了三维空间曲面。这一工序对于加工工艺的要求是比较严格的,一般是根据封闭槽转角处空曲面的形成原理,采用圆弧刀具与两轴数控联动的合成形成所需的空间曲面,完成加工要求。

    最后是完成机架制造过程中的孔底大型过渡圆R弧的加工。一般是在侧压孔孔底处,有大型过渡圆弧R,其范围大约为R30~R50mm。使用一般R镗刀是无法加工的,设计专用R镗刀,完成了孔底大型过渡圆弧的加工。

    以上简单为大家介绍了关于机架制造的主要工艺措施,相信在了解这些内容之后,大家对于机架制造这一环节有了更为全面的认识。

In the manufacturing process of the frame, the main process flow includes the processing of the workpiece loading card, the processing of the datum surface, the machining of the closed groove shape, and the processing of the large transition circular R arc of the hole bottom. Among them, the main problem is to consider the placement of rack during manufacturing.

Next is the machining of the base level of the rack manufacturing parts. Generally, the datum plane mainly includes: installation base surface and foundation surface. In particular, the base surface is the most important base surface. The 4 horn milling head is used to install the knife plate, half semen, two times milling out the base surface and the base surface, and ensuring the perpendicularity of the two base surfaces. At the same time, the control size is 665, and the size is measured to be used for the processing of the other frame.

The next is to complete the closed groove. For example, in the manufacturing process of a rack, the closed groove has a transitional arc R30 to R50mm at the bottom, forming a three-dimensional surface at the corner. This process is strictly required for the processing technology. In general, it is based on the forming principle of the empty surface at the corner of the closed groove. The required spatial surface is formed by the synthesis of the arc cutting tool and the two axes numerical control linkage, and the processing requirements are completed.

Finally, the processing of the large transition circular R arc of the bottom hole in the rack manufacturing process is completed. Generally, there is a large transition arc R at the bottom of the side pressure hole, which ranges from R30 to R50mm. The general R boring cutter is unable to be machined. The special R boring cutter is designed to complete the processing of the large transition arc at the bottom of the hole.

This is a brief introduction to the main technical measures of the frame manufacturing. We believe that after understanding the contents, we have a more comprehensive understanding of the frame manufacturing.
