Embodiment 1

[0028] The thin steel ring 1 used by a certain type of helicopter has 12 through holes 2 with a diameter of 8.5mm evenly distributed along the circumference. The thickness of the thin steel ring 1 is t=2mm, and the outer diameter of the thin steel ring 1 is D=300mm. The radial width of 1 is s=25mm; the processing steps are as follows:

[0029] 1. Cutting: use CNC milling machine to cut a round wool, the thickness of the wool is t1=7mm, and the outer diameter of the wool is D1=340mm;

[0030] 2. Rough machining: CNC milling machine is used, the pressure plate is pressed on the edge of the wool, and a circular groove is milled on the upper surface of the circular wool to form the first blank. The bottom of the circular groove forms the web 3, and the inner diameter of the web 3 is D1=315mm. The thickness of the web 3 is t, and the groove wall of the circular groove forms an annular skirt 3a;

[0031] 3. Drilling: Using a CNC machine tool, drill 12 through holes 2 of 8.5mm along...

[0038] The thin steel ring 1 used by a certain type of helicopter has 20 through holes 2 with a diameter of 8.5mm evenly distributed along the circumference, the thickness of the thin steel ring 1 is t=3mm, and the outer diameter of the thin steel ring 1 is D=400mm. The radial width of 1 is s=30mm; the processing steps are as follows:

[0039] 1. Cutting: use CNC milling machine to cut a round wool, the thickness of the wool is t1=10mm, and the outer diameter of the wool is D1=460mm;

[0040] 2. Rough machining: Using a CNC milling machine, the pressure plate is pressed on the edge of the wool, and a circular groove is milled on the upper surface of the circular wool to form the first blank. The bottom of the circular groove forms the web 3, and the inner diameter of the web 3 is D1=418mm. The thickness of the web 3 is t, and the groove wall of the circular groove forms an annular skirt 3a;

Abstract

The invention belongs to mechanical processing technology and relates to a thin steel ring processing method. The thin steel ring processing method is characterized by including the following steps of blanking, roughing, drilling, milling of an annular groove, cutting of a skirt edge, clamping of a second blank, finish-milling of inner and outer circles and deburring. By the thin steel ring processing method, requirements on planeness of a thin steel ring 1 are guaranteed.

Description

technical field [0001] The invention belongs to mechanical processing technology and relates to a processing method of a thin steel ring. Background technique [0002] figure 1 It is a schematic diagram of the structure of a thin steel ring used in a helicopter. The thin steel ring 1 has 10 and 40 through holes 2 uniformly distributed along the circumference, the thickness of the thin steel ring 1 is t=2mm~6mm, the outer diameter of the thin steel ring 1 is D=300mm~500mm, and the radial direction of the thin steel ring 1 is The width s=25mm-50mm, and the flatness of the thin steel ring 1 is 0.2mm. The general stamping processing method cannot guarantee the flatness requirement. Contents of the invention [0003] The object of the present invention is to propose a processing method for the thin steel ring so as to ensure the flatness requirements of the thin steel ring 1 . [0004] The technical solution of the present invention is: a processing method of a thin steel r...
