Uthotho Lokusebenza Komatshini Wokwenza Ityhubhu ye-ERW – Icandelo lesi-2: Ulungelelwaniso Oluchanekileyo kunye Nohlengahlengiso Lokusebenza Okufanelekileyo

Kwinxalenye yangaphambili, sigubungele amanyathelo abalulekileyo okuqhawula, ukuhlola, ukuphaka, kunye nokwenza uhlengahlengiso oluqatha kumatshini wakho omtsha wokwenza iityhubhu ze-ERW. Ngoku, siqhubekela kwinkqubo ebalulekileyo yokulungelelanisa ngokuchanekileyo kunye nokulungisa, into ephambili ekuqinisekiseni ukuveliswa kweetyhubhu ezikumgangatho ophezulu kunye nokusebenza ngokufanelekileyo.

Ukuqonda Uhlengahlengiso: Injongo Yokulungelelaniswa Okugqibeleleyo

Uhlengahlengiso, kule meko, lubhekisa ekulungisweni kakuhle kwenkqubo yokwenza i-roll ukuqinisekisa ukuba i-tube blank ihamba kakuhle nangokuzinzileyo kumatshini, ekugqibeleni ivelise iityhubhu ezihlangabezana neemfuno ezifunekayo. Ukuba umatshini unako ukuvelisa iityhubhu ngale ndlela, kunokuthiwa "uhlengahlengiso" lube yimpumelelo. Uhlengahlengiso olongezelelweyo ngexesha lokwenziwa kwemveliso rhoqo ludla ngokuthathwa njengo "ukusombulula iingxaki" xa izinto zingasebenzi njengoko bekulindelwe.

Ukulungiswa kweyunithi yetyhubhu ye-weld kunokwahlulwa ngokwamanyathelo alandelayo:

I. Ukulungiselela kubalulekile: Ukuhlola iiRolls kunye nokuvavanya imeko yomatshini

Ngaphambi kokuba ungene kwinkqubo yokulungisa, ukulungiselela ngononophelo kubalulekile:

• Ukuhlolwa koMgangatho weRoll:Gxila kwimilo yomngxuma owenza i-roll. Sebenzisa itemplate ukuqinisekisa ukuba imilo ye-roll nganye iyahambelana neemfuno zoyilo. Lahla nayiphi na i-rolls engahlangabezani nemigangatho. Kwakhona, qaphela ububanzi besiseko se-roll. Oku kuqinisekisa ukuba yonke i-rolls iyajikeleza ngokulinganayo. Izibini ezihambelanayo ze-rolls kufuneka zilingane ngobukhulu kunye nemo.
• Ukujonga Imeko Yomatshini:Qinisekisa ukuba umatshini usebenza kakuhle. Oku kungashwankathelwa ngolu hlobo lulandelayo:
  • Ii-axes ezithe tye mazibe zilingana.
  • Ii-axes ezithe nkqo mazithe tye.
  • Indawo yokuqengqeleka kufuneka ihlale izinzile.
  • Izinto ezityibilikayo mazihambe ngokukhululekileyo nangokutyibilikayo.
  • Uhlengahlengiso kufuneka lube lula.

  Ukuba umatshini awuzifezekisi ezi mfuno, yenza ulondolozo ukuze ubuyisele kwisakhono sawo sokusebenza esisisiseko. Kubalulekile ukulungisa nantoni na ebonisa le ndlela ilandelayo: ukungakwazi ukulungisa, ukungaguquguquki emva kokulungiswa, okanye indawo yokushukuma.

II. Ulungelelwaniso Oluchanekileyo: Isiseko seMveliso yeetyhubhu ezisemgangathweni

1. Ulungelelwaniso lweGroove

Ukulungelelaniswa kwe-groove linyathelo lokuqala kwinkqubo yokulungisa.

• Khetha ucingo lwentsimbi oluyi-0.5mm. Lusebenzise kunye neerola zokufunxa zomatshini wokwenza izinto ukuya kwiirola zokulungisa zomatshini wokulinganisa njengobude besiseko.
• Misela umbindi womgca wokuqengqeleka. Qinisekisa ucingo lwentsimbi uze ulumise njengomgca othe tye nongashukumiyo.
• Qinisekisa ukuba ukuphakama kocingo lwentsimbi kuphezulu kancinci kunobubanzi obusezantsi berola ethe tyaba (2mm nangaphezulu). Ngale ndlela kuya kuthintela ukudibana ne-arc yomsele oya kuchaphazela umlinganiselo kunye nendawo efanelekileyo. Olu cingo lwentsimbi luya kuba ngumgca wesalathiso sokulungelelaniswa komsele.

2. Ulungelelwaniso lweRoller oluthe tye

Kukho iindlela ezimbini zokulungelelanisa imiqolo ethe tye:

• Indlela yoku-1: Sebenzisa i-motor yokulungelelanisa ukulungisa umahluko wobukhulu phakathi kwee-groove rollers ezahlukeneyo. Nangona kunjalo, ukuba ukuchaneka kokucubungula iindawo akuhlangabezani neemfuno, iimpazamo eziqokelelweyo zinokwenzeka ngokulula emva kokuhlanganiswa, zichaphazele ngokuthe ngqo isiphumo sokulungelelaniswa kweemilo ze-roll.
• Indlela yesi-2: Sebenzisa i-lock nut ukulungisa indawo yeerola kwi-shaft, ukuze iziko le-groove yerola nganye lihambelane nomgca ophakathi. Itemplate ekhethekileyo isetyenziselwa ukujonga indawo ye-groove center. Xa ujonga, faka itemplate kwi-groove elungelelanisiweyo, uze uphakamise kancinci isiphelo esingaphezulu. Xa ucingo lwentsimbi lunokuwela kakuhle kwi-groove ephakathi yetemplate, kubonisa ukuba indawo ephakathi ye-groove ichanekile, kungenjalo, kufuneka ukulungiswa kwentshukumo ye-axial. Le yindlela elula yokulungelelanisa.

Ukulungelelanisa iirola eziphezulu kusebenzisa iirola ezisezantsi njengesalathiso. Emva kokubala umgama ophakathi phakathi kweerola ezithe tyaba eziphezulu nezisezantsi, lungisa iirola eziphezulu zibe kwindawo ethe tye. Ifomula yokubala umgama ophakathi kwe-axial yile ilandelayo:

• Ukubalwa komgama we-Open Groove Axial Center:H = (Dlower + Dupper) ÷ 2 + t – a
• Ukubalwa komgama weGroove Axial Center evaliweyo:H = Dlower + 2R – aWhere:
  • I-Dlower = Ububanzi obusezantsi berola esezantsi (mm)
  • I-Dupper = Ububanzi obungaphandle be-roller ephezulu (mm)
  • t = Ubukhulu obungenanto betyhubhu (mm)
  • R = Irediyasi yomjelo wobungakanani (mm)
  • a = I-coefficient yokunciphisa (0.1～0.5)

  Ubungakanani be-coefficient a buxhomekeke kakhulu kubukhulu betyhubhu engenanto, ubungakanani bokunciphisa ububanzi bangaphandle betyhubhu, ubungakanani kunye neenkcukacha, kunye nemeko yokwenyani efana nobubanzi be-shaft kunye nokuguquguquka kwe-elastic kwe-shaft. Nangona kunjalo, ukuqengqeleka okubandayo akunakwenzeka kumatshini wokwenza. Nokuba ubungakanani bokunciphisa obukhethiweyo bufanelekile na bunokulinganiswa kwaye bujongwe ngamanqaku okutsalwa kwentambo yefuse. Xa uthatha isampuli, qala kuqala iyunithi kwaye uyivule ngesantya esicothayo, uze ugobe intambo yefuse enobubanzi obukhulu kancinci kunobukhulu betyhubhu engenanto ukuze ifane nomngxuma, kwaye uyifake kancinci kwi-rolling mill ukuze ufumane ukutsalwa kwentambo yefuse.

Emva kokuba i-roller ephezulu ilinganisiwe, indawo ephakathi ye-axial ye-roller ephezulu ye-groove evulekileyo ingafakwa embindini nge-template-style plug gauge ukujonga ukuba umsantsa phakathi kwamacala amabini e-roller groove esezantsi kunye ne-roller groove ephezulu uyafana na. Ukuba ziyafana, indawo ephakathi ye-roller ephezulu ingatshixwa. Sebenzisa indlela yokuchukumisa kwi-grooves evaliweyo ukujonga ukuba i-grooves ephezulu nesezantsi ziyahambelana na.

3. Ulungelelwaniso lweRoller ethe nkqo

Ulungelelwaniso lwe-roller ethe nkqo lunokwahlulwa lube ngamanyathelo amathathu:

• Okokuqala, misela umsantsa wokuvula weqela ngalinye leerola ezithe nkqo, oko kukuthi, umgama ophakathi kwe-axial phakathi kweerola ezimbini ezithe nkqo;
• Emva koko, fumana indawo esembindini yeqela ngalinye leerola ezithe nkqo;
• Okokugqibela, lungisa ukuphakama kweerola ezithe nkqo.

Umsantsa wokuvula werola ethe nkqo kufuneka usekelwe kububanzi bokuvula obuguquguqukayo ngexesha loyilo lwemilo yerola, uze unciphe malunga ne-5mm. Ukuba ubungakanani bokuncipha bukhulu kakhulu, kuya kukhawulezisa ukuguguleka komphetho ongasentla wemilo yerola ethe nkqo kwaye kwandise umthwalo kwizixhobo.

Umbindi werola ethe nkqo kufuneka ulungelelaniswe ngaxeshanye nerola ethe nkqo ukuqinisekisa ukuba iindawo eziphakathi zeerola ezithe nkqo nezithe nkqo zikwimigca efanayo esembindini. Emva kokuba umgca osembindini werola ethe nkqo ufunyenwe, ucingo lwentsimbi lunokwehliswa luye kwindawo enobubanzi obuphantsi berola ethe nkqo, kwaye ukuphakama kwerola ethe nkqo kungaqaliswa. Ukuphakama kwerola ethe nkqo kufuneka kusekelwe kubude bomphetho ongezantsi werola ethe nkqo ehambelana nokuphakama kocingo lwentsimbi. Ukuphakama kweerola ezimbalwa zokuqala ezithe nkqo ngaphambi kokuba kwenziwe kufuneka kumiselwe ngokweeparamitha zenkqubo yenani lokusikwa kweringi yerola esezantsi.

4. Ezinye iindlela zokulungelelanisa iGroove

Indlela yokulungelelanisa ezinye iimilo zeroli ingabhekisa kumgaqo wokulungelelanisa iiroli ezisicaba kunye neeroli ezithe nkqo. Kuphela kukuba indawo yobubanzi obusezantsi beroli esezantsi yeroli yesikhokelo kufuneka ibe phezulu kancinci kunomgca wesalathiso nge-0.5 ～2 mm (kuxhomekeke kububanzi kunye nobukhulu bodonga lwetyhubhu evelisiweyo). Iroli yenkxaso ye-burr kufuneka ibe phezulu nge-0.5 mm kunomgca wesalathiso ukwenza amandla azinze ngakumbi xa kucwangciswa ii-burrs zangaphandle kwaye kuthintelwe ukucwangciswa ekutsibeni.
