Kuyini I-Dry-Cutting for Metal?

Ukuqonda Amasaha Ensimbi Eyindilinga

Njengoba igama lisho, isaha lensimbi eliyindilinga lisebenzisa izindwani ezimise okwediski ukusika izinto. Lolu hlobo lwesaha lulungele ukusika insimbi ngoba idizayini yalo ivumela ukuthi ihlale iletha ukusikeka okunembile. Ukwengeza, ukunyakaza kwe-blade okuyisiyingi kudala isenzo esiqhubekayo sokusika, okusivumela ukuba sinqamule ezinsimbi ezisansimbi nezingezona ayoni.I-Dry-cutting iyindlela yokusika ngensimbi ngaphandle kokusebenzisa uketshezi olupholile. Esikhundleni sokusebenzisa uketshezi ukuze kuncishiswe ukushisa nokungqubuzana, ukusika okomile kuncike kuma-blade enziwe noma ambozwe ngawo, into engakwazi ukumelana nokushisa nokungqubuzana okudalwa yinsimbi. Ngokuvamile, izindwani zedayimane zisetshenziselwa ukusika okomile ngenxa yokuqina nokuqina kwazo.

Ama-saw blades ayindilinga asetshenziselwa ukusika insimbi azokhipha ukushisa okuningi lapho esika insimbi eyindilinga, i-aluminium nezinye izinto ezikhethekile; kodwa ngezinye izikhathi kuyadingeka ukugcina i-workpiece esaha kanye ne-saw blade ipholile. Kulesi simo, i-special I-saw blade ye-circular ye-blade yezinto ezibonakalayo iqedela ukusika, okuyi-saw ebandayo.

Imfihlo yekhono le-sawing elibandayo lokugcina i-workpiece ne-saw blade ipholile yikhanda elikhethekile lokusika: ikhanda lokusika i-cermet.

Amakhanda e-Cermet cutter agcina izici ze-ceramics ezifana nobunzima obuphezulu, amandla aphezulu, ukumelana nokugqoka, ukumelana nokushisa okuphezulu, ukumelana ne-oxidation kanye nokuzinza kwamakhemikhali, futhi abe nokuqina okuhle kwensimbi kanye nepulasitiki. I-Cermet inezinzuzo zombili zensimbi ne-ceramic. Inobunzima obuphansi, ubulukhuni obuphezulu, ukumelana nokugqoka kanye ne-conductivity enhle yokushisa. Ngeke ibe brittle ngenxa yokupholisa kungazelelwe noma ukushisa. Ngesikhathi sokusika, ama-serration ekhanda le-ceramic cutter azohambisa ukushisa kuma-chips, ngaleyo ndlela kugcinwe i-saw blade nezinto zokusika zipholile.

Cold Sawing Izinzuzo

Amasaha abandayo angasetshenziselwa ukusika izimo eziningi ezihlukene, okuhlanganisa izinduku, amashubhu, kanye nama-extrusions. Amasaha abandayo ayindilinga azenzakalelayo, avalelwe asebenza kahle ekugijimeni kokukhiqiza namaphrojekthi aphindaphindayo lapho ukubekezelelana nokuqeda kubalulekile. Le mishini inikeza isivinini se-blade esiguquguqukayo kanye namazinga okuphakelayo alungisekayo okukhiqiza isivinini esikhulu kanye nokusikeka okunganaburr, okunembile.Amasaha abandayo ayakwazi ukukhanda ama-alloys amaningi ayonileyo nangewona. Izinzuzo ezengeziwe zifaka ukukhiqizwa okuncane kwama-burr, izinhlansi ezimbalwa, ukuguquguquka okuncane nothuli.

Inqubo yokusaha ebandayo iyakwazi ukuphumela phezulu ezinsimbi ezinkulu nezisindayo - ezimeni ezithile, iqine njengo ±0.005” (0.127 mm) ukubekezelela. Amasaha abandayo angasetshenziselwa ukunqanyulwa kwazo zombili izinsimbi ezisansimbi nezingezona ayoni, futhi kukho kokubili ukusikeka okuqondile nokune-engeli. Isibonelo, amamaki avamile ensimbi abolekisayo futhi angakwazi ukusika ama-sawing amaningi ngokushesha.

Ezinye I-Downsides Ukuze Amasaha Abandayo

Kodwa-ke, ukusaha okubandayo akulungile kubude obungaphansi kuka-0.125” (3.175 mm). Ukwengeza, indlela ingakhiqiza ama-burrs asindayo. Ngokukhethekile, kuyinkinga lapho unama-OD angaphansi kuka-0.125” (3.175 mm) kanye nama-ID amancane kakhulu, lapho ishubhu izovalwa khona i-burr ekhiqizwa isaha elibandayo.

Okunye okubi kumasaha abandayo ukuthi ukuqina kwenza amasaha abe brittle futhi ashaqeke. Noma yiliphi inani lokudlidliza - isibonelo, kusukela ekubambeni okunganele kwengxenye noma izinga lokuphakela elingalungile - lingalimaza kalula amazinyo asaha. Ngaphezu kwalokho, amasaha abandayo ngokuvamile abangela ukulahlekelwa okukhulu kwe-kerf, okuhumushela ekukhiqizeni okulahlekile kanye nezindleko eziphezulu.
Nakuba i-sawing ebandayo ingasetshenziselwa ukusika ama-alloys amaningi ayoni kanye ne-non-ferrous, akunconyelwe izinsimbi eziqinile kakhulu - ikakhulukazi, lezo eziqinile kunesaha ngokwalo. Futhi ngenkathi amasaha abandayo ekwazi ukusika izibopho, angakwenza kuphela ngezingxenye ezincane zobubanzi futhi kudingeka ukulungiswa okukhethekile.

Ama-Hard Blades Wokusika Ngokushesha

I-cold sawing isebenzisa i-blade eyindilinga ukuze isuse izinto ngenkathi idlulisela ukushisa okukhiqizwa kuma-chips adalwe yi-saw blade. Isaha elibandayo lisebenzisa insimbi eqinile enesivinini esikhulu (HSS) noma i-tungsten carbide-tipped (TCT) blade ejika ngama-RPM aphansi.
Ngokuphambene negama, ama-HSS blades awavamile ukusetshenziswa ngesivinini esiphezulu kakhulu. Esikhundleni salokho, isici sabo esiyinhloko siwubulukhuni, okubenza bakwazi ukumelana nokushisa nokugqoka. Ama-TCT blades abiza kakhulu kodwa futhi aqinile ngokwedlulele futhi ayakwazi ukusebenza emazingeni okushisa aphakeme ngisho nangaphezulu kune-HSS. Lokhu kuvumela amasaha e-TCT ukuthi asebenze ngamanani ashesha kakhulu kunama-HSS blades, kunciphisa kakhulu isikhathi sokusika.

Ukusika ngokushesha ngaphandle kokukhiqiza ukushisa nokungqubuzana okukhulu, izindwani zomshini wokusaha ezibandayo zimelana nokugqoka ngaphambi kwesikhathi okungase kuthinte isiphetho sezingxenye ezisikiwe. Ngaphezu kwalokho, zombili izinhlobo zama-blades zingalola kabusha futhi zingasetshenziswa izikhathi eziningi ngaphambi kokuba zilahlwe. Le mpilo ende yensingo isiza ukwenza ukusaha okubandayo kube indlela engabizi kakhulu yokusika ngesivinini esikhulu kanye nokuqedwa kwekhwalithi ephezulu.

Amaphutha Avamile Okufanele Ugwenywe Lapho Insimbi Yokusika Eyomile

Njengoba usebenzisa i-blade eqinile kunensimbi, ukusika okomile kungaba nzima kumathuluzi akho. Ukuze ugweme umonakalo noma izingozi ngenkathi usika insimbi, nanka amaphutha avamile okufanele uwabheke:

Isivinini seBlade Esingalungile: Uma usomile-usika ngensimbi, kubalulekile ukunaka isivinini se-blade. Uma i-blade yakho ihamba ngokushesha kakhulu, ingabangela insimbi ukuthi igobe noma igobe futhi iphule i-blade yakho. Ngakolunye uhlangothi, uma ihamba kancane kakhulu, ukushisa kuzokwanda esaha lakho futhi kungalilimaza.

Ukubamba Ngokungafanele: Qinisekisa ukuthi ubamba ngokuphephile noma iyiphi into yensimbi oyisikayo. Izinto ezihambayo ziyingozi futhi zingadala umonakalo omkhulu.

Uma usebenzisa noma yimuphi umshini wokusaha obandayo, kubalulekile ukukhetha iphimbo lamazinyo elifanele lezinto ezisikwayo.

Ukukhetha i-tooth pitch efanelekile ye-saha yakho ebandayo kuzoncika kulokhu:

* Ukuqina kwempahla

* Ubukhulu besigaba

* Ukujiya kodonga

Izingxenye eziqinile zidinga ama-blade ane-pitch yamazinyo amaholo, kuyilapho amashubhu amabonda amancane noma umumo onezingxenye ezincane eziphambanayo udinga ama-blade anephimbo elicolekile. Uma unamazinyo amaningi kakhulu ezintweni ngesikhathi esisodwa, umphumela uzobe uklebhuka esikhundleni sokukhishwa kwe-chip. Lokhu kuholela ekwenyukeni okuphezulu kwengcindezi yokugunda.

Ngakolunye uhlangothi, lapho usika izindonga ezisindayo noma okuqinile usebenzisa i-pitch yamazinyo amahle kakhulu, ama-chips azozungeza ngaphakathi komgudu. Njengoba izingqimba zamazinyo anamazinyo amancane, ama-chips aqoqiwe azodlula umthamo we-gullets futhi acindezele ezindongeni zezinto zokusebenza okuholela ekutheni ama-chips agxume futhi abambeke. I-cold saw blade izoqala ukusebenza sengathi ayisika, kodwa lokho kungenxa yokuthi ayikwazi ukuluma ngamagobolondo aminyene. Uma uphoqa i-blade, uzobhekana nokusika okungekuhle kanye nokucindezeleka okuphawulekayo kokugunda, okungase kuholele ekuphukeni kweblade yakho ebandayo.

Sicela uqaphele ukuthi nakuba ukukhetha i-tooth pitch efanele yohlelo lwakho lokusebenza kubaluleke kakhulu, akuyona ukuphela kwento enquma i-blade yesaha ebandayo engcono kakhulu yohlelo lwakho lokusebenza.Ngokufana namanye amathuluzi, ukusebenza kahle kwesaha elibandayo nokuphila isikhathi eside kuncike kakhulu kwikhwalithi yezingxenye ezibalulekile ezifana ne-blade. I-HERO ithengisa amasaha abandayo angcono kakhulu njengoba sisebenzisa umshini wobungcweti owenziwe eJalimane ukudala imikhiqizo yethu. Ama-blade ethu azokusiza ukusika insimbi kumaphrojekthi amaningi.Singakujabulela ukusiza ngocingo!
