NPT kunye neempawu zayo

Ukuproseswa intonga yesinyithi okanye ityhubhu ngokubangela zomsonto isixhobo akhethekileyo ekuthiwa uxhulumaniso threaded. It lisetyenziswa nati, izikhonkwane, iibholiti, ezithi ke ngoko esetyenziswa ukuhlanganisa amacandelo ahlukeneyo kunye neendibano, nemisonto umbhobho isetyenziselwa ufakelo umbhobho.

Imiba ephambili yolu hlobo lwe compound detachable inowuthi yayo, iprofayili, ubunzulu vee kunye ububanzi we lwangaphandle nangaphakathi. Iinkangeleko zahlulwe iintlobo: trapezoidal, ezibunxantathu, uxande kunye nabanye. Yintoni inkangeleko? Ukuba wenza umnqamlezo-candelo, ngoko ukufumana ifomu yaye iprofayili.

Ufuna ntoni injongo, le nto iza kusetyenziswa kwi kumsonto umbhobho isenokuba ekhohlo okanye ekunene. Kwakhona, oko kwahlulwa ibe ezizodwa kunye dunnage.

Uhlobo ezingundoqo ukulungisa zithako inkangeleko olunxantathu, kunye noqhagamshelo ezikhethekileyo - eziziingxande, kunye nenani ezinye iindidi profiles.

Ukukrola, yasetyenzwa phezu izikhonkwane, iibholiti, amandongomane - unxantathu, kuba isetyenziselwa izinto zokubopha. Umgama phakathi crests okanye imisele zeenqwelwana ezimbini amagophe uvale ngokuba inyathelo. Ubunzulu yikhompawundi olunjalo umgama ukusuka ezantsi ukuya kwindawo phezulu coil.

Ukulungisa pipe intambo okanye ezibunxantathu, na intshi metric. Ngokuqhelekileyo, oko ke izinto zokubopha iphambili isixhobo ngomatshini. Ngobubanzi, ngaphakathi nangaphandle, alinganiswa iimillimitha, kwaye inyathelo azinamsonto, ngaphandle iimillimitha, nkqu kwizabelo zawo.

Kodwa umbhobho intambo intshi une-engile 55 degrees, nangona iprofayile iyafana naleyo metric. umahluko wabo ukuba imilinganiselo kwenzeka intshi kunokuba eemilimitha ngenxa langutela enkulu.

Xa ufaka imibhobho imibhobho zisetyenziswa yaye iindawo nge-intshi azinamsonto. Yena lokubopha nogwali. On imibhobho ngenxa yokuba ubunzulu bayo lilawulwa Ebubanzini umbhobho iindonga, imisonto ezincinane. Kodwa kwakhona ngenxa yokuba inani elikhulu amagophe - uqhagamshelwano ezingqongqo. Kodwa ukuba iikhompawundi ophumelelayo kwamanani kophahla ezifanelekileyo umsonto, leyo, njengoko kucacisiwe apha ngentla, isikwe iibholiti, izikrufu, amandongomane, ezenziwe ngentsimbi eqinileyo.

Ukulungisa umbhobho intambo, ukongeza ukugawula oluzenzekelayo, oko bonqanyulwa ngesandla kunye nokusetyenziswa idayisi. Amacwecwe kwakhona zohlulwa ngokwendidi, ngokuxhomekeke kwifowuni zabo. Ba prismatic, ngeenxa zonke, ukutyibilika kunye iyonke.

Umzekelo, zisa iyafa, asike ngomsonto elipheleleyo ukuthintela oomahluko ezincinane intonga ubukhulu sisinyithi. Ukusebenzisa i iyafa ngeenxa yonke, ezinxaxhileyo ubukhulu kakade ayamkelekanga.

Yangaphakathi kwi umbhobho ngolu hlobo lulandelayo: kuyimfuneko ukuba ibambelele nkqo ukufaka nokukhusela workpiece, nokusebenzisa swa setyhula, ukuba bawele ubude ezicwangcisiweyo ngexesha. Ukuba kukho ziyasetyenziswa sliding iipleyiti, Novunayo luya kuqhubeka abapasileyo amabini okanye amathathu.

Xa ukusika ekunene uqhagamshelwano Screw kufa imfuyo kufuneka ijikelezwe ku ekunene egqibela ukusika - ekhohlo, ngoxa ndizilibala ukwenza isibini amagophe emva ukususwa. Xa konke sekulungisiwe, inokumana itshekishwa kunye nati uncedo urhangqo.

Xa inkqubo ngokusika umbhobho sentsimbi izinto womsonto ngokwayo kufa shushu. Kuba abo Ukupholisa ukusetyenziswa sulfofrezol okanye iyoma ioli. Sokwehlisa elingqukuva intsimbi ithe turpentine khulu.

Jiko lwangaphakathi kunqunyulwa itephu. Ngendlela efanayo kubhaliwe bawafaka ukubambelela inxenye, kwaye sele umngxuma itephu lokuqala lugqityiwe ukubala. Emva ukususwa umaleko yesinyithi, ukusebenzisa i iitephu yesibini neyesithathu, ndinqumle babetshintshana esele ngokupheleleyo. Ngalo lonke ixesha qinisekisa ukuba into yokuba ezimanyeneyo umngxuma itephu lo mdlalo. Ukususela kumaxesha ngamaxesha, ukhulule impompo kwelinye icala ¼ vula ukususa engenelela.
