Izinyathelo zokuvimbela deformation of amasaha ayindilinga by high-frequency ukuqina umshini ukucisha nezindlela zokulinganisa

1. Ibhodi le-saw kufanele lingene endaweni yokupholisa ngokuqondile ngesikhathi sokucisha, ukuze iziphetho zombili zebhodi le-saw zipholile ngesikhathi esifanayo. Uma uwoyela usetshenziswa njengendawo yokupholisa yokucisha, ngokuvamile kungcono ukuyilawula ku-60-90°C. Uma izinga lokushisa likawoyela lingaphansi kuka-50 ℃, ukuguqulwa kwebhodi lesaha kuzokwanda, futhi kunengozi engaba khona yokucisha ukuqhekeka. Ukuze kuncishiswe ukucindezeleka, ukucisha i-austempering noma i-graded quenching kungasetshenziswa.

2. Ngaphansi kwesisekelo sokuqinisekisa ukuqina, indlela yokushisa yokucima amandla iyamukelwa ukuze kuncishiswe umthelela wamagagasi kagesi endaweni yokusebenza.

3. Uma ukulinganisa kusahluleka ukuhlangabezana nezidingo ngemva kwezinguquko ezimbili zesigaba, ungasebenzisa isando esibandayo sokulinganisa, kodwa ubuchwepheshe bokubethela budinga kakhulu, futhi ukuguqulwa kuzokwanda uma kungalungile.

4. Iphoyinti lika-Ms lensimbi engu-65Mn lilinganiselwa ku-270 ℃. Lapho ukuguqulwa kwe-martensitic kwenzeka, ipulasitiki yensimbi inhle kakhulu. Uma ibhodi le-saw libekwe phakathi kwamapuleti amabili ngalesi sikhathi, lingaphoqeleka ukuba lifinyelele ezingeni.

5. Inqubo yokuguqulwa kwesigaba eyenzeka lapho ibhodi lesaha lilinganisiwe lingasetshenziselwa ukulinganisa okuqhubekayo. Hlanza ingaphezulu le-saha blade ngaphambi kokuthambisa ukuze unciphise iphutha elinqwabelene ngesikhathi sokupakishwa. Ukushisa kufanele kucindezelwe ngepuleti eliyisicaba futhi isikhathi sokushisa kufanele sanele.

6. Ukushisa kokushisa kufanele kuthathe umkhawulo ongaphezulu, futhi isikhathi sokushisa kufanele sanele ukuzinzisa isakhiwo sangaphakathi sebhodi le-saw, ukunciphisa iphuzu le-Ms, ukwandisa inani le-austenite egcinwe ngemva kokucisha, nokunciphisa ukuguqulwa kwebhodi le-saw. .
