IsiKhokelo esiPheleleyo se-HSS Saw Blades: Ukusika okuchanekileyo kwizicelo ezifunwayo

Ukuqonda iTekhnoloji yeHSS: iMetallurgy eyenza umahluko

I-High-Speed ​​Steel (HSS) i-saw blades imele i-revolutionary progression kwi-teknoloji yokusika, ukudibanisa i-alloys yentsimbi kunye nezongezo zeqhinga ze-tungsten (14-18%), i-molybdenum (5-8%), i-chromium (3-4.5%), i-vanadium (1-3%), kunye ne-cobalt (5-10%). Le iresiphi yesinyithi entsonkothileyo yenza ukuba iincakuba zigcine ubulukhuni obukhethekileyo kumaqondo obushushu angaphezulu kwama-600°C – inzuzo ebalulekileyo apho iincakuba zentsimbi zekhabhoni zinokwehla ngokukhawuleza. Ngokungafaniyo neeblade eziqhelekileyo, ukwahluka kwe-HSS kugcina i-Rockwell Hardness (HRC) ye-62-67 naphantsi koxinzelelo olugqithisileyo lwe-thermal, iguqulela ngokuthe ngqo ekusebenzeni okuzinzileyo kokusika ngexesha lokusebenza ixesha elide.

I-Shanghai Easydrill ihambisa iinkqubo zokucoca ubushushu be-vacuum ngokuchanekileyo ukuze kunyuswe ubume bekristale be-M2, i-M35, kunye ne-M42 yebakala le-HSS. Le ndlela yobuchule iqinisekisa ukusasazeka kobunzima obufanayo ngejometri yezinyo ngelixa kugcinwa ukuqina okuyimfuneko kumzimba we-blade-ibhalansi ebalulekileyo ekuthinteleni ukusilela kwamazinyo ngexesha lokusika umthwalo omkhulu.

Izinto eziluncedo kwezobuGcisa ezitshintsha imisebenzi yokusika

1. Ukunganyangeki koBubushushu kunye nokuSebenza kokuNxitywa
   Iintsimbi ze-HSS zigqithisa iintsimbi eziqhelekileyo ze-carbon steel nge-3-5x kwiimeko zokusika ubushushu obuphezulu. Uphando lubonisa ukuba xa isantya sokusika sinyuka ukusuka kwi-170 mm / min ukuya kwi-220 mm / min, ii-HSS blades zibonisa kuphela i-19% ephezulu yokunxiba kokuqala xa kuthelekiswa ne-56% yokugqoka i-acceleration kwizixhobo eziqhelekileyo - ebonisa ukuzinza okuphezulu kwe-thermal 1. Oku kuguqulela ngokuthe ngqo kwiinkonzo ezongezelelweyo kunye nokunciphisa ixesha lokunciphisa.
2. Umgangatho woMphezulu ochanekileyo
   Uvavanyo olulawulwayo lubonisa ukuba ii-HSS blades zigcina umgangatho ophezulu wokugqitywa (amaxabiso eRa) ngenxa yokukwazi ukugcina imiphetho ebukhali yokusika. Xa amazinga okutya enyuka ukusuka kwi-425 mm/min ukuya kwi-550 mm/min, ii-HSS blades zibonisa kuphela ukwanda koburhabaxa nge-10-14% xa kuthelekiswa ne-25%+ kwezinye iindlela 1. Oku kubenza babe yimfuneko kwizicelo ezibalulekileyo kwi-aerospace kunye nokuveliswa kweemoto.
3. Ukuguquguquka kuzo zonke izixhobo
   Ibhalansi yobulukhuni obukhethekileyo yenza ukuba kusetyenzwe ngokufanelekileyo kwezinto ezahlukeneyo:
   • Izinyithi: Ingxubevange yentsimbi (<45 HRC), i-aluminiyam, ubhedu, i-iron ductile
   • Iimbumba: CFRP, GFRP ngaphandle delamination
   • Iiplastiki: I-Akriliki, inayiloni, i-thermoplastics eyomeleziweyo
   • Iinkuni: Iiplanga eziqinileyo, iibhodi ezilayitiweyo ezinezibophelelo ezifakwe ngaphakathi

Izicelo zoShishino Apho ii-HSS Blades Excel

Ukusebenza kwesinyithi kunye noomatshini
I-Shanghai Easydrill's HSS blades ilawula kumaziko enkonzo yesinyithi alungisa intsimbi, imibhobho, kunye neeprofayili ezikhutshiweyo. Iijiyometri zamazinyo eziguquguqukayo (i-Triple Chip Grind, i-Alternate Top Bevel) inqanda ukungcangcazela kwe-harmonic xa usikwa iityhubhu ezinodonga olucekethekileyo, ngelixa iingubo ezikhethekileyo ezifana ne-TiN zomeleza ukuthambisa ekusikeni kwentsimbi engenasici.

UkuVeliswa kweeMoto
Imigca yemveliso isebenzisa iibhleyidi ze-HSS ezidityanisiweyo nge-pulsed-laser ukwenzela:

• Ukwenziwa kwecandelo le-injini (i-nodular iron castings) 1
• Ukugqunywa kwezixhobo zokuhambisa
• Ukwenziwa kwecandelo lokunqunyanyiswa
  Iimpawu zokudambisa iincakuba zingqineke zibalulekile ekugcineni ukunyamezelana okumalunga ne-±0.1mm kwidimensional kwiisarha ezizisebenzelayo eziphakamileyo zeRPM.

I-Aerospace kunye noKhuseleko
Kwi-alloys ye-nickel ebalulekileyo (i-Inconel 718, i-Ti-6Al-4V), ii-cobalt-enriched M42 blades ziqhuba kwiiparamitha eziphuculweyo:

• Ukusika isantya: 80-120 SFM
• Isantya sokutya: 0.8-1.2 mm / izinyo
• Ukupholisa: 8% emulsion yokwenziwa
  Oku kuthintela ukuqina komsebenzi ngelixa ufezekisa i-Ra <1.6μm umphezulu ogqityiweyo ofunekayo kumacandelo endiza.

Ukukhetha eyona HSS Blade: Iiparamitha eziphambili

Iingqwalasela zeJiyometri yezinyo

• Ii-Angles zeHook: +10 ° ukuya +20 ° kwiintsimbi ezithambileyo; -5 ° kwizinto ezinqabileyo
• Ukuxinwa kwezinyo: 60-80 TPI ye-tubing eludongeni oluncinci; I-8-14 TPI yesitokhwe esiqinileyo
• Uyilo lweGullet: Iiprofayili ze-curvilinear ezinzulu zokukhutshwa kwetshiphu okusebenzayo

IziKhokelo zokuSebenza ngokuPhucula
Ngokusekwe kuhlalutyo loyilo lovavanyo lweeparamitha zoomatshini 1:

1. Beka phambili ukulawulwa kwesantya sokusika (Vc) kubomi besixhobo - i-20% isantya esigqithileyo sibangela i-56% yokukhawuleza yokunxiba
2. Lungisa ireyithi yesondlo (F) yokugqiba umphezulu – i-30% yokwanda inyusa iRa nge-14% ubukhulu
3. Ibhalansi ubunzulu bokusika (Dp) kunye nomthwalo we-chip - ungaze udlule ububanzi be-blade × 1.2

Ukusilela amaqhinga oThintelo

• Beka iliso kwiivibrations ze-harmonic ezibonisa umonakalo wamazinyo
• Hlola i-micro-chipping kwi-50% yobomi besixhobo
• Sebenzisa izibane zestrobe ukuqinisekisa ukuhambelana kokwakheka kwetshiphu
