Iindaba - Indlela Yokufumana Amazinyo Afanelekileyo Kwi-Blade Yakho Yesarha

Kwicandelo lokusika kwemizi-mveliso, iiblade zesarha zihlala ziphazanyiswe njengezinto ezisetyenziswayo. Nangona kunjalo, kwiinjineli ezinamava okanye abaphathi bemveliso, iblade yesarha sisixhobo esiyilwe ngokuchanekileyo. Umgangatho wesiphumo sokusika udla ngokuxhomekeka ekuphambukeni kweedigri ezimbini ukuya kwezintathu kwijiyometri yeprofayili yamazinyo, okunokukhokelela ekuqhekekeni okukhulu kweblade yesarha okanye kubangele umphezulu wokusika ogudileyo njengesipili.

Ngeli xesha sijonga iimpawu zomzimba zee-engile zamazinyo e-saw, size sichaze indlela iimilo zamazinyo ezithile ezichaphazela ngayo ukwakheka kobushushu, umthwalo weetshiphusi kunye nomgangatho wokusika kwiintlobo ezintathu eziphambili zezinto: iintsimbi ze-ferrous (ukusika okomileyo), umthi kunye nezinto ezidityanisiweyo zokwakha.

Indlela Ezino Ezibukeka Ngayo

Ngaphambi kokuba sihlalutye usetyenziso oluthile, kufuneka silungiselele isigama sethu esisemgangathweni malunga nemilinganiselo emithathu ebalulekileyo ye-angular echaza ukusebenza kokusika.

I-Rake Angle yi-engile yobuso bezinyo xa ithelekiswa nomgca we-radial otsalwe embindini we-blade ukuya kwincam yezinyo.

Umsebenzi:Imisela "ubundlongondlongo" bokusika. Ilawula i-engile ye-shear plane—i-engile apho izinto ziguquguquka khona kwaye zahlulwe kwindawo yokusebenza.

Umthetho weThumb:Ii-engile ezintle kakhulu zifuna amandla amancinci kodwa zivelisa ukugqitywa okurhabaxa kunye nokuqina komphetho ophantsi. Ii-engile ezimbi zifuna amandla angaphezulu kodwa zibonelela ngolawulo oluphezulu kunye namandla omphetho.

I-Angle yokuCacisa (i-Angle yoNcedo) —β

Le yintsimbi ephezu kwezinyo ekude nomphetho ophambili.

Umsebenzi wayo kukuthintela iincam ze-carbide ukuba zingakhuhli kwizinto ozisikayo.

Nantsi intengiselwano:Ukuba i-engile ityebile kakhulu, iincam zamazinyo ziya kuba buthathaka kwaye zingabi nankxaso, nto leyo ekhokelela ekuqhekekeni. Ukuba ayinzulu kakhulu, ukungqubana kuya kuvelisa ubushushu obugqithisileyo, okubangela ukwanda kobushushu kwaye ekugqibeleni kutshise isixhobo somsebenzi.

I-Radial (Ecaleni) Clearance

Le engile iyanciphisa izinyo ukusuka phambili ukuya ngasemva emacaleni.

Inciphisa ukungqubana phakathi kwamacala amazinyo kunye neendonga ze-kerf (indawo yokusika). Kwimisebenzi yokusika eyomileyo apho kungekho lubricant yokupholisa amacala amazinyo, le engile ibaluleke kakhulu ekuthinteleni ubushushu ukuba buqokelelane.

Iintsimbi zeFerrous (Isarha ebandayo eyomileyo)

Ingqwalasela: Ulawulo lobushushu kunye nokumelana nempembelelo

Iisarha ezibandayo ezisikiweyo (ezifakwe iincam ze-cermet okanye ze-carbide ezigqunywe nge-coated) zezona ntlobo zinzima kakhulu kwezobuchwepheshe ukuyila. Nantsi ke injongo echasene nengqiqo: sifuna ukuvelisa ubushushu, kodwa kufuneka sibususe ngoko nangoko.

Ngexesha lokusika okomileyo, ubushushu buveliswa kukuguquka kwesinyithi ngeplastiki. Ijiyometri yesixhobo kufuneka idlulisele malunga ne-80% ukuya kwi-90% yobo bushushu kwiitships—ngale ndlela, zombini iblade kunye nesixhobo sokusebenza zihlala zipholile. Yile ndlela kanye esebenza ngayo umgaqo "wokusika okubandayo".

Ijiyometri ye "Cold Cut"

Xa sisika intsimbi ethambileyo, sidla ngokusebenzisa iprofayili yokugaya iitshiphusi ezintathu (TCG). Kodwa i-engile iya kwahluka ngokuxhomekeke kwisakhiwo sentsimbi.

Usetyenziso lweZityana (iityhubhu, i-Angle Iron, iiChannels)

I-Angle yeRake: Ilungile (+5° ukuya ku +10°)

I-engile yokuVula: 10° ukuya kwi-$12°

Ukuqiqa:Ukuphuma okuphezulu kancinci kunceda izinyo liphume kakuhle kwisilonda ngaphandle kokutsala i-burr edla ngokwenziwa ngaphakathi kwityhubhu.

Izicelo Eziqinileyo (I-Bar Stock, Ipleyiti Etyebileyo)

I-Angle yeRake: Ukusuka kwi-zero ukuya kwi-low, i-positive 0° ukuya kwi-+3°

IFiziksi:Xa usika intsimbi eqinileyo, izinyo lidibana nezinto ezo ixesha elide, nto leyo edala umthwalo oqhubekayo, onefuthe eliphezulu. I-engile ebukhali neyakhayo ishiya incam ye-carbide ingaxhaswa kwaye ibuthathaka.I-engile ye-Zero Rakeiqondisa amandla okusika ngasemva aye emzimbeni we-blade, isebenzisa amandla oxinzelelo lwe-carbide (ephezulu) kunokuba isebenzise amandla ayo okucheba (aphantsi).

I-engile yokuCacisa: 8°

Ukuqiqa:I-engile esezantsi yokuvula i-engile yongeza "inyama" engaphezulu emva komphetho wokusika, isebenza njengesinki sobushushu kunye nenkxaso yesakhiwo.

Intsimbi Engagqwaliyo (Umngeni Wokwenza Umsebenzi Ube Luqilima)

I-Angle yeRake: 0°ukuya ku +5°
Ingqwalasela ekhethekileyo:Intsimbi engagqwaliyo (njenge-SUS304) idla "ngokusebenza nzima" xa ikhuhliwe.kufunekasike, ungatyibiliki. Nangona ireyikhi engenalo inika amandla, sihlala sifuna enkulu kancinciI-Angle yokuCacisa (12)°)kunokuba isetyenziselwa intsimbi ethambileyo. Oku kuqinisekisa ukuba emva kokuba isikiwe, umva wezinyo awuchukumisi izinto, nto leyo "ebuyela umva" kancinci ngenxa yokuqina kwayo.

Izicelo Zokusebenza Ngokhuni

Ingqwalasela: Isikhokelo seeNkozo kunye nokuSika iiFayibha

Umthi yinto esetyenziswa njenge-anisotropic—iimpawu zawo zomzimba ziyahluka ngokuxhomekeke kwicala lamandla ahambelana nengqolowa. Ke ngoko, i-geometry yeblade yesarha kufuneka ivumelane nengqolowa.

A. Ukukrazula (Ukunqumla ngeenkozo)

Ukukrazula ngokuyintloko ngumsebenzi wokutshiza. Injongo kukukhupha imicu emide yefayibha endleleni.
- I-Angle yeRake: Ixabiso Eliphezulu Elihle (+20)°ukuya kuthi ga kwi +25°)
- Ijiyometri: I-Flat Top Grind (FTG)
- IFiziksi:I-engile ephezulu yehoko isebenza njengeplani yesandla, ikhupha izinto ngokukhawuleza. Le engile inamandla itsala umthi ungene kwi-blade. Nangona oku kuvumela amazinga okutya akhawulezayo (abalulekile kwiifektri zokwenza imithi), ishiya umphezulu urhabaxa.
- Into Ebangela Ubuhlungu Emathunjini:"I-Gullet" (intlambo ephakathi kwamazinyo) kufuneka ibe nzulu kwaye ibe nkulu. Imicu emide yeenkozo yenza ii-chips ezinkulu; ukuba i-gullet incinci kakhulu, uthuli lwesarha luyaxinwa, ludale ukungqubana kwaye lutshise umthi (kunye neblade).
B. Ukunqumla (Ukunqumla ingqolowa)

Ukunqumla imicu kufuna ukunqumla imicu ethe nkqo kwindawo enqunyulweyo. Ukuba usebenzisa i-ripping blade (FTG) apha, iya "kuqhushumba" okanye iqhekeza umthi kwicala lokuphuma.
- I-Angle yeRake: Iphakathi Elungileyo (+10)°ukuya kuthi ga kwi-+15°)
- Ijiyometri: I-Alternate Top Bevel (ATB) okanye i-Hi-ATB
- IFiziksi:Amazinyo ajijelwe ukuze enze iindawo ezifana neemela kumacala atshintshanayo. Abeka imicu ekhohlo nasekunene kwe-kerfngaphambiukususa izinto ezisembindini. I-engile yereki esezantsi (10°vs 20°) inciphisa "ukubamba" kweblade, ivumela isenzo sokucheba esithambileyo esishiya isiphelo esicociweyo.

Ayinazo iiFerrous kunye neeComposites

Ingqwalasela: Ukhuseleko kunye nokumelana nokurhawuzelelwa

A. I-Aluminiyam kunye neeMetali ezingezizo iFerrous

I-Aluminium ithambile, ithambile, kwaye ayinakunyibilika kakhulu. Idume ngokuba "yi-gummy" kwaye idla ngokuvalela amazinyo ee-blade.
- I-Angle yeRake: Imbi (-5)°ukuya ku -6°)
- Ijiyometri: I-TCG
- Ifiziksi yoKhuseleko:Ukuba usebenzisa i-angle ye-hook (njenge-blade yomthi) kwi-aluminiyam, i-blade iya "kunyuka" iye kwisixhobo. Kwi-chop saw ngesandla, oku kunokutsala isiphatho se-saw ngamandla okanye kuphose i-workpiece.I-Rake engalungangai-engile itshintsha i-force vector: ityhala izintokudeukusuka kwincakuba nangaselucingweni olungasemva, ukuqinisekisa ukuba inqunyulwa ngokukhuselekileyo nangokulawulwayo.
- Ukuthambisa:Ngokungafaniyo nokusika intsimbi eyomileyo, i-aluminium idla ngokufuna ukuthambisa ngenkuthalo ukuthintela iitships ukuba zingawelisi kwimiphunga.
B. IiComposites zokwakha (iiLaminates, iMelamine, iFiber Cement)
- I-Angle yeRake: Imbi (-2)°ukuya kuthi ga kwi -5°)
- IFiziksi:Izinto ezifana neMelamine zinomphezulu oqinileyo noqinileyo weglasi phezu kwesiseko sebhodi ethambileyo. I-hook ethambileyo iphakamisa izinto phezulu, ibangela ukuba umphezulu oqhekekileyo uqhekeke.I-Hook Engalungangaucinezela izinto ezantsi ngexesha lokusika, ucinezela umaleko womphezulu kwaye uthintele ukuqhekeka.
- Inqaku lezinto eziphathekayo:Kwisamente yefayibha (umxholo wesilika orhabaxa kakhulu), i-engile ayibalulekanga kangako kunezinto ezikwincam.Idayimani yePolycrystalline (PCD)Iingcebiso ziyimfuneko ukuze umntu aphile ixesha elide, zihlala zinee-engile ezintle eziphantsi (+5°) ukulawula umthwalo onzima wothuli.
