| Popis: | For manufacturing thin-walled shafts for gas turbine engines of heat-resistant steels and alloys, the labor-intensive multistage drawing of a sheet of the workpiece in dies is used. The following problem is posed in the work: to study the possibility of manufacturing such parts by a less labor-intensive method: the rotary drawing of a thick-walled workpiece (sheet) by a spinning lathe by rolling a roll under hot deformation conditions. For this purpose, the computer and physical modeling of the rolling process of hollow shafts of a thick-sheet steel workpiece was carried out. The important parameters of the technological process of manufacturing a geometrically complex shaft are determined: the initial workpiece shape and the changes in its shape when rolled on a mandrel mounted on the spindle of the spinning lathe of the PNC 600 type. The research results are used for rolling full-size shafts of chromium steel of the EI962-Sh grade. |
