Embodiment 1

[0046] A processing method for the bearing cage of an integral shield machine is as follows: Step 1, cutting in sections: firstly lay the blank of the cage flat, pad it flat, and leave a gap under the workpiece to facilitate the blowing of iron oxide slag; For cutting and blanking, the purity of the gas is controlled at 99.7%. According to the size of the drawing, the amount on one side is 8mm, and it is divided into three sections. Each section of the bearing retainer blank maintains a bending arc of 120°;

[0047] Step 2. Grinding and spot welding of the retainer: Grind the flame-cut retainer blanks respectively to remove edges and burrs so that the surface of the retainer blanks is smooth and does not scratch hands; the retainer with three sections of curvature of 120° , fixed connection by spot welding;

[0048] Step 3. Rough milling the inner diameter of the retainer: According to the size requirements of the process drawing, rough mill the inner diameter; make the surfac...
