I-screw barrel ngundoqo womatshini wakho wokubumba inaliti. Inyibilikisa iplastiki yakho, iyixube, kwaye iyityhalele ekubumbeni - umjikelo emva komjikelo, iminyaka. Xa ingalunganga kwisicelo sakho, uyibona kuyo yonke indawo: ubunzima bokudubula obungahambelaniyo, iziphene ezingaphezulu, amachaphaza amnyama, kunye nokunyuka kwamazinga okulahlwa. Esi sikhokelo sigubungela zonke iingongoma zesigqibo ukuze usifumane kakuhle okokuqala.

Eyona nto iyenzayo iScrew Barrel

I-screw kunye nebhere isebenza njengesibini esihambelanayo. Nalu ulandelelwano kumjikelo ngamnye:

  1. Ukutya— Iipilisi zePlastiki ziwa ukusuka kwihopper ukuya kwindawo yokutya.
  2. Ukunyibilika— Isikrufu esijikelezayo sivelisa ubushushu obuchetyiweyo. Idibaniswe nezifudumezi ze-barrel, iipellets ziyanyibilika kwaye zicinezele.
  3. Ukulinganisa- Ukunyibilika kuba yinto efanayo kwiqondo lokushisa kunye noxinzelelo ngaphambi kokutofa.
  4. Isitofu— Isikrufu sibheka phambili njengeplunger, sityhala iplastiki etyhidiweyo kwisingundo.

Yonke into eguquguqukayo yoyilo-ijometri, imilinganiselo yezowuni, unyango lomphezulu-ichaphazela indlela ezo nyathelo zine zenzeka ngayo. Ukungafani kuyo nayiphi na enye kuzo kubonakala njengengxaki yemveliso.

Isigqibo 1: Umlinganiselo we-L/D

Umlinganiselo we-L/D (ubude be-screw flighted by the diameter) lelona nani libalulekileyo kwi-spec sheet. Ilawula ixesha lokuhlala, umgangatho wokuxuba, kunye nokusabalalisa ubushushu.Uninzi lwezicelo zokubumba iinaliti zenjongo jikelele zisebenzisa i-20:1.

Umgaqo:Iireyini ezizinzile ngobushushu zihamba ixesha elide (i-L / D ephezulu). Iireyini ezingeva bubushushu ziba mfutshane.
Intlaka L/D ecetyisiweyo
PP, PE, PS (esemgangathweni) 18:1 – 20:1
ABS, PC 20:1 – 24:1
I-PVC (ayivani nobushushu) 16:1 – 20:1
I-PET 20:1 – 22:1
Inayiloni (PA) 18:1 – 20:1
Izixhobo zokuqinisa i-GF 20:1 – 24:1

Isigqibo sesi-2: Umlinganiselo woxinzelelo

Umlinganiselo woxinzelelo (CR) ulinganisa ukuba ijelo le-screw liyancipha kangakanani ukusuka kwindawo yokutya ukuya kwindawo yokulinganisa. I-CR ephezulu icinezela ukunyibilika ngamandla - ilungile kwii-amorphous resins ezithamba kancinci kancinci. I-CR esezantsi ithambile, yiloo nto uyidingayo kwizinto ezingeva lubushushu okanye zizaliswe yifiber.

 Ngezinto ezizaliswe yi-GF, i-CR ephezulu kakhulu yophula iifiber zeglasi. Oko kwenza buthathaka inxalenye yokugqibelakwayeikhawulezisa ukunxiba screw ngaxeshanye.
Intlaka Umlinganiselo woxinzelelo
ABS, PC, PMMA (amorphous) 3.0 - 3.5:1
PP, PE, Inayiloni (semi-crystalline) 2.5 – 3.0:1
I-PVC 2.0 - 2.5:1
I-PET 2.3 – 2.6:1
GF-yomelezwe (≥15%) 2.0 - 2.5:1

Isigqibo sesi-3: Ubungakanani boMmandla

Isikrufu sokutofa esisemgangathweni sahlulahlulwe ngokwezowuni ezintathu. Umyinge wezowuni nganye ubaluleke kakhulu njengetotali ye-L/D.

  • Indawo Yokutya (L1):Iitshaneli ezinzulu ezamkela iipellets eziqinileyo ukusuka kwi-hopper. Ixesha elide = umthamo ongaphezulu wokuphuma.
  • Indawo yoxinzelelo (L2):Ubunzulu bomjelo buyancipha ngokuqhubekayo. Uninzi lokunyibilika lwenzeka apha.
  • uMmandla wokulinganisa (L3):Imijelo enzulu, engaguqukiyo. Iqinisekisa ubushushu obufanayo bokunyibilika kunye noxinzelelo phambi kokutofa.
Intlaka Ukutya (L1) Uxinzelelo (L2) Ukulinganisa (L3)
PP / PE 50% 25% 25%
ABS / PC 40% 40% 20%
I-PET 40% 40% 20%
Inayiloni (PA) 35–45% 35–40% 20–25%
I-PVC 35% 50% 15%

Isigqibo sesi-4: Izinto ze-Screw Barel

38CrMoALA — Isiseko soMgangatho

Izikrufu zokubumba iinaliti zikaNanhaiya zenziwe ukusuka38CrMoALA intsimbi yengxubevange, iphathwe ngobushushu kwaye yacinywa. Esi siseko siphatha i-thermoplastics eqhelekileyo njenge-PE, PP, PS, kunye ne-ABS kakuhle, kunye nobomi benkonzo obuphantse bube.10,000–20,000 iiyurephantsi kweemeko eziqhelekileyo zokusebenza.

Nitriding

I-gesi nitriding kwi-500-560 ° C yenza i-nitrided layer0.5-0.8mm ubukhulungobulukhuni be950–1050 HV (~62 HRC). Oku kuphucula ukuxhathisa ukunxiba nge-30-40% xa kuthelekiswa nentsimbi engaphathwanga. Umgangatho wosetyenziso oluninzi lwenaliti esebenzayo engazaliswanga okanye imathiriyeli ezaliswe kancinci.

Iimpawu zesilumkiso Isikrikri sakho sangoku asilunganga ngomsebenzi

  • Amachaphaza amnyama okanye amabala atshileyo- Ukuthotywa kwezinto ngenxa yexesha elininzi lokuhlala okanye indawo eshushu. Jonga imimandla yobushushu bomgqomo kunye nokususwa kwesijivu.
  • Ubunzima bokudubula obungahambelaniyo— Rhoqo ivalufa engabuyiyo egugileyo okanye isikrufu esigqithileyo somgqomo esivumela umva.
  • Dlala amanqaku kumphezulu— Ukufuma okanye irhasi ekunyibilikeni. Isenokubonisa ukomisa kwangaphambili okungonelanga okanye ijiyometri ejijwayo engaphumi kakuhle.
  • Ukuchacha okucothayo / ixesha lomjikelo omde— Umthamo weplastiki awanelanga. I-Screw diameter inokwandiswa.
  • Inkunkuma ephezulu ekutshintsheni umbala— Ukuxubana kakubi kwindawo yokulinganisa. I-Maddock okanye isithintelo sokuxuba into eyongeziweyo kwi-screw ihlala iyisombulula le nto.

Imibuzo ebuzwa qho

Ngowuphi umlinganiselo we-L/D osetyenziswa ngoomatshini abaninzi bokubumba?
Umlinganiselo we-20: 1 screw L/D lukhetho oluqhelekileyo kumatshini wokubumba inaliti yenjongo jikelele. Ukuba ulungisa iiplastiki zobunjineli ezibandakanya i-PC kunye ne-ABS, ukukhetha umlinganiselo we-22: 1-24: 1 kuya kuphucula kakhulu umphumo wokuxuba izinto kunye nokunyibilika kwe-homogeneity.
Ndiwufuna nini umphanda we-bimetallic endaweni ye-nitriding eqhelekileyo?
Ukuba usebenzisa imathiriyeli engaphezulu kwe-15% yefayibha yeglasi, isihluzi seminerali, okanye i-resin ezonakalisayo njengePVC, i-bimetallic iya kudlula umphanda we-nitrided ngo-3–5× phantsi kwezo meko. Kwi-thermoplastics eqhelekileyo engagcwaliswanga, i-nitriding yanele.
Ithetha ukuthini i-38CrMoALA?
Ngumgangatho wentsimbi yealloyi esetyenziswa kakhulu kwimibhobho yesikrufu. Ukubunjwa (i-chromium, i-molybdenum, i-aluminium) inika amandla angundoqo kunye nokuphendula okunamandla kwi-nitriding. Emva kwe-nitriding yegesi, ubunzima bomhlaba bufikelela kwi-950-1050 HV, malunga ne-62-65 HRC.
Ngaba ndingasebenzisa i-screw barrel enye kwii-resins ezininzi?
I-screw ye-nitrided yenjongo jikelele isebenza kakuhle kuyo yonke i-thermoplastics eqhelekileyo-i-PP, i-PE, i-ABS, i-PS. Kodwa ukuba utshintsha rhoqo phakathi kwee-resin ezonakalisayo nezingonakalisiyo, okanye phakathi kwezixhobo ezingazaliswanga nezizaliswe kakhulu, izikrufu ezinikezelweyo kwintsapho nganye ye-resin ziya kuba neendleko ezithe kratya ixesha elide.
Ingaba umphanda ojijwayo kufuneka uhlale ixesha elingakanani?
Isikrufu se-nitrided esiqhuba iPP engagcwaliswanga kwimveliso eqhubekayo sihlala sihlala iiyure eziyi-10,000–20,000. Ukubaleka i-30% yenayiloni ye-GF ngokusebenzisa isikrufu esifanayo kusika ubomi kakhulu. I-spec efanelekileyo ibaluleke ngaphezu kwegama lebhrendi.
