Ukucinywa kwamazinyo uhla lwe imishini yokushisa imvamisa ephezulu

Izimo zesevisi yokwelapha ukushisa kanye nezidingo zokusebenza kwezikulufu zebhola: Isikulufu siyingxenye ebalulekile yokudlulisela kumathuluzi omshini ahlukahlukene. Iyingxenye yokusebenza kokudlulisa nokubeka eguqula ukunyakaza okuzungezayo kube ukunyakaza okuqondile noma ephendule ukunyakaza ngomugqa kube ukunyakaza okujikelezayo. Kunezigaba ezimbili eziyinhloko zezikulufu zamathuluzi omshini: izikulufu ze-trapezoidal nezikulufu zebhola. Phakathi kwazo, isikulufu sebhola sinokusebenza kahle kokudlulisela okuphezulu, isenzo esibucayi, iyunifomu nokuphakelayo okuzinzile, akukho kukhasa ngesivinini esiphansi, ukunemba kokuma okuphezulu nokuphindaphinda, nempilo ende yesevisi. Isetshenziswa kabanzi kumathuluzi omshini we-CNC nasezikhungweni zomshini.

I-screw yebhola ivamise ukugotshwa, i-torsion, ukukhathala, kanye nomthelela lapho isebenza, futhi ngesikhathi esifanayo ithwala ukungqubuzana ezingxenyeni ezishelelayo nezizungezayo. Izinhlobo eziyinhloko zokulimala kwesikulufu sebhola ukuguga nokukhathala. Ngakho-ke, izidingo zayo zokusebenza ukuthi yonke kufanele ibe nezakhiwo ezinhle ezibanzi zemishini (okungukuthi, inhlanganisela ethile yamandla nokuqina) kanye nokuzinza okuphezulu kwe-dimensional, futhi izingxenye zokusebenza ezifanele (umzila womjaho, ububanzi be-shaft) kufanele zibe nobulukhuni obukhulu, amandla aphezulu. futhi okwanele Ukumelana nemihuzuko.

Incazelo yenqubo yokucisha yentambo yesikulufu sebhola:

Okokuqala faka ucezu lokusebenza ku-inductor (ikhoyili), lapho imvamisa ethile yamanje eshintshanayo idlula ku-inductor, inkambu kazibuthe eshintshanayo izokhiqizwa eduze kwayo. I-electromagnetic induction yenkambu kazibuthe eshintshanayo ikhiqiza amandla amanje avaliwe endaweni yokusebenza ─ eddy current. Ukusatshalaliswa kwamandla okusebenza endaweni ephambanayo ye-workpiece akulingani kakhulu, futhi ukuminyana kwamanje ebusweni bomsebenzi wokusebenza kuphezulu kakhulu futhi kancane kancane kuncipha ngaphakathi. Lesi simo sibizwa ngokuthi umphumela wesikhumba. Amandla kagesi we-high-density current ebusweni bomsebenzi wokusebenza aguqulwa abe amandla okushisa, ukuze izinga lokushisa lendawo likhule, okungukuthi, ukushisa kwendawo kuyabonakala. Uma uphakeme imvamisa yamanje, mkhulu umehluko wamanje wokuminyana phakathi kobuso nengaphakathi le-workpiece, futhi uba mncane ungqimba lokushisa. Ngemuva kokuthi izinga lokushisa lesendlalelo sokushisa lidlule izinga lokushisa elibalulekile lensimbi, lipholiswa ngokushesha ukuze kuzuzwe izinqubo zokucisha indawo kanye nezinqubo zokushisa ukushisa.
