specific Embodiment approach 1

[0116] Embodiment 1: Combining Figure 1 to Figure 2 Illustrating this embodiment, a processing method for preventing deformation of an elastic ring described in this embodiment is performed according to the following steps:

[0117] Step 1: After the parts are clamped and fixed, car a ring, leaving 8mm allowance on the inner and outer circles of the ring, and the two ends are not car; Step 2: Stress relief and tempering;

[0118] Step 3: Turn each end face of the part;

[0119] 3.1. Clamp the parts on the three-jaw chuck of the machine tool and fix them;

[0120] 3.2. All surfaces of A1, B1, C1, D1, E1, F1, G1, and H1 of the vehicle standard (this process diagram is compared with the drawing size, and each surface has machining allowance);

[0121] 3.3. Pack the parts processed in step 3.2 into the packing box and proceed to the next sequence;

[0122] Step 4: Grind the A2 and B2 sides of the part; remove the allowance evenly on both ends, and remove 0.3mm allowance on eac...

specific Embodiment approach 2

[0217] Specific implementation mode 2: Combining figure 1 Illustrating this embodiment, the cutting parameters in step 3 of this embodiment are: cutting speed (m / s): 0.3-0.5; feed (mm / r): 0.1-0.15; cutting depth (mm): 0.5 -1.

[0218] Other components and connection relationships are the same as in the first embodiment.

specific Embodiment approach 3

[0219] Specific implementation three: combination figure 2 Illustrating this embodiment, the grinding depth of cut (mm) described in step 4 of this embodiment is ≤ 0.01.

[0220] Other compositions and connection relationships are the same as in the first or second embodiment.

Abstract

A processing method for preventing deformation of an elastic ring, the present invention relates to a processing method for an elastic ring, in order to solve the problem that the elastic ring is easily deformed during the processing, for such an extremely deformable elastic ring, the Test processing, explore the reasons for its deformation, break the conventional processing method, strictly control the processing parameters and cutting methods of each sequence, gradually improve the processing method, control its deformation, ensure its strict parallelism, and improve the qualified rate of products. The invention belongs to the technical field of machining.

Description

technical field [0001] The invention relates to a processing method for an elastic ring, in particular to a processing method for preventing deformation of the elastic ring, and belongs to the technical field of mechanical processing. Background technique [0002] The elastic ring in a gas turbine unit is not only a typical thin-walled part, but also a special structural part. The requirements for this part are higher in the later assembly. In the processing, whether it is the outer circle of the inner hole, the grinding plane, the concave surface or the milling boss, etc. If the whole processing process is processed according to the conventional method, it will cause serious deformation and cannot guarantee its strict parallelism, which will affect the assembly of the product parts and reduce the qualified rate of the product. SUMMARY OF THE INVENTION [0003] In order to solve the problem that the elastic ring is easily deformed during processing, the present invention f...
