Start the Excircle machining that lathe carries out described seal disc, stay the 2mm surplus;
Figure 2012104038899100002DEST_PATH_IMAGE005
The upper lower plane of rough turn described seal disc stays the finish turning thickness surplus of 1 ~ 1.5mm;
Figure 378760DEST_PATH_IMAGE002
In former step processing, the depth of cut is 0.7 ~ 0.8mm, and the depth of cut is that 0.5mm/ turns, and cutting speed is 40m/min;
⑸ finish turning:
By the surplus that the described seal disc cylindrical of figure paper size elder generation's finish turning stays, the described seal disc lower sealing surface of finish turning is fallen 0.7mm with top unnecessary surplus finish turning at last again, guarantees up and down two plane keeping parallelisms;
⑹ moulding:
Figure 725427DEST_PATH_IMAGE004
Described seal disc raw material is placed in the described cylinder carcass concave station, uses the amesdial centering;
Figure 137954DEST_PATH_IMAGE005
Utilize the screw hole at described cylinder carcass concave station edge that described seal disc is compressed;
Figure 697111DEST_PATH_IMAGE002
Measure first thickness and other size and the record of supplied materials behind the centering before the upper slitter, and be fixed on the Lathe bench;
Start lathe, unnecessary surplus is fallen 5mm with 19 ~ 26 m/min cars; Simultaneously in process, described seal disc is added cooling fluid continuously and cool off, when described seal disc deflection is 5 ~ 6mm, get final product, detect simultaneously workpiece temperature, must not be greater than 40 ℃.
The present invention compared with prior art has the following advantages:
1, the present invention's supporting tool of using simple frock, being consisted of by batten and hand jack, when being worked into the seal disc center, be difficult for producing vibration, simultaneously can also slow release because the continuous pressure that produces of processing, this is because batten hardness is little, after stressed, the top meeting of jack slowly embeds in the batten, and seal disc center deflection can be smaller behind lax workpiece, thereby when reducing the seal disc deflection, process qualified workpiece, reach and not only guarantee precision but also indeformable purpose.
2, the inventive method is simple, not only effectively shortens the production cycle, has improved productivity ratio, has ensured heat exchanger internals sealingly secure, and to there being other Large Dimension Thin-wall Machining that good reference function is arranged.
