Example Embodiment

[0028] Example 1

[0029] Choose ANSI310, high chromium nickel austenitic stainless steel material, first form the thin-walled shielding ring casting blank, and heat treatment. Then, according to the processing technology of the present invention, rough machining → natural aging treatment → semi-finishing machining → rough milling groove → finishing → finishing groove milling, wherein the natural aging treatment is placed for 4 days, and the final thin-walled shielding ring size is as follows Figure 2 to Figure 5 Shown. among them, figure 2 Is a three-dimensional view of the thin-walled shielding ring, image 3 for figure 2 The front view of the thin-walled shielding ring, Figure 4 Then figure 2 Right view of the thin-walled shield ring. The size of the six notches 11 of the thin-walled shielding ring is 10.414±0.38mm wide and 9.83±0.1mm deep. Figure 5 for Figure 4 An enlarged view of the dotted line, where a=0.38±0.127mm, b=3.3±0.5mm, c=1.52±0.38mm, d=7.8±0.2mm, and e=12...

Abstract

The invention discloses a machining process of a thin-wall groove milling stainless steel part. The machining process of the thin-wall groove milling stainless steel part mainly comprises the following steps of heat treatment of a rough casting, rough machining, natural aging processing, subsequent rough groove milling, finish machining and finish groove milling. Through the design of a machining route, the machining process of the thin-wall groove milling stainless steel part reduces production of stress as much as possible, and effectively avoids deformation caused by stress concentration, thereby improving machining precision and the accuracy degree.

Description

technical field [0001] The invention relates to a processing technology of mechanical parts, in particular to a processing technology of thin-wall groove milling stainless steel parts. Background technique [0002] In the development process of a new domestic train, it involves the machining of a shielding ring. The blank of the part is cast and the material is stainless steel. The ratio of inner hole diameter to hole depth is 389.5 / 88.9=4.38, and the minimum wall thickness is 3.3mm. The minimum tolerance of the inner hole is 0.076mm, there are 6 grooves with a width of 9.7mm on the outer circle of the flange, the position of the groove is 0.05mm, and the flatness of the large end face of the flange is 0.13mm. Due to the thin-walled structure of the part itself, the stainless steel material is easy to deform, and the internal stress of the workpiece is large after clamping and processing, it is difficult to meet the design requirements of the part in batch processing on ordi...
