Indlela yokusika ithumbu le-ptfe?

Uwusika njani umbhobho we-PTFE ukunqanda ukonakalisa umbhobho?

I-PTFE ityhubhu iphathwa ngokubanzi ngumatshini wokusika.Ukusika umatshini wokusikaPTFE ityhubhuinokuthintela ngempumelelo i-tube deformation.Akukho nto ibuhlungu ngaphezu kokugwaza umnwe ngomphetho ogqithisiweyo we-hose ephothiweyo.Intlungu yokujongana nezi zinto zifanelekile, ngakumbi xa ufuna intambo ehlala ixesha elide.Akukho nto inokuhambelana nokumelana nokunxiba kwe-hose yentsimbi ephothiweyo.Kukho iingcebiso omele uzazi xa ufuna ukusika i-hose ephothiweyo.Uphendlo oluNxulumeneyo:ithumbu eligudileyo, ithumbu le-PTFE elibhinqiweyo

Umbhobho wePolytetrafluoroethylene (PTFE) luhlobo oluphezulu lombhobho weplunger extrusion.Itekhnoloji ekhethekileyo yokucubungula yamkelwa ukwenza umbhobho wentsimbi kunye nombhobho weplastiki ngokusondeleyo.Iyakwazi ukuthwala uxinzelelo oluyi-1.6Mpa kunye noxinzelelo olubi lwe-77kpa.Ingasetyenziswa ngokuqhelekileyo ukusuka kwi-60℃ukuya + 260℃.Inokwethenjelwa kunye nokumelana nokugqwesa okugqwesileyo.Iyakwazi ukuthutha irhasi eyomeleleyo eyingozi kunye nolwelo phantsi kobushushu obuphezulu, obungenakutshintshwa ngenye imibhobho Inozinzo oluhle kakhulu lweekhemikhali, inokumelana nazo zonke ii-acids ezinamandla, iziseko eziqinileyo, i-oxidants ezomeleleyo, kwaye ayidibanisi neentlobo ezahlukeneyo ze-solvents eziphilayo.Emva kokuba umbhobho we-PTFE wenziwe, ubude bombhobho kufuneka bunqunywe.Isixhobo esikhoyo sokusika umbhobho we-PTFE, emva kokusika umbhobho we-polytetrafluoroethylene, kufuneka kwakhona abasebenzi bahambe baye kwicala le-workbench ukutyhala umbhobho, Kuyinkcitho yexesha kunye nokuphazamiseka ukusika umbhobho.Ngoko ke, isixhobo sokusika sokwenziwa kombhobho we-polytetrafluoroethylene sicetywayo.

Imiba yophumezo lobuchwephesha:

Injongo yemodeli yokusetyenziswa kukubonelela ngesixhobo sokusika sokwenza umbhobho we-polytetrafluoroethylene, ukwenzela ukusombulula iingxaki eziphakanyiswe kwi-teknoloji yangasemva.

Ukuze kuphunyezwe le njongo ingentla, imodeli eluncedo ibonelela ngesikimu sobugcisa silandelayo: isixhobo sokusika sokwenziwa kwemibhobho ye-polytetrafluoroethylene, kubandakanywa ne-worktable, indawo engaphezulu ye-worktable inikezelwa ngesibiyeli, umbindi wendawo ephantsi ye-polytetrafluoroethylene. inkxaso idityaniswe ngokusisigxina kunye ne-cylinder ye-hydraulic, i-shaft ephumayo ye-hydraulic cylinder idibaniswe ngokuthe ngqo kunye ne-cutter, kwaye umbindi wendawo ephezulu ye-worktable inikwe i-groove yokuqala I-groove yokuqala ibekwe ngokuthe ngqo ngaphantsi komsiki, icala elinye lomjelo wokuqala libonelelwe ngomqolo wesibini, umjelo wesibini ubonelela ngomzimba wepleyiti yokuqala, udonga lwangaphandle lomzimba wepleyiti yokuqala lufakwe ngokufanayo kunye nebhloko yesilayidi sokuqala, ibhloko yokuqala yokutyibilika izilayidi kwigroove yesibini. , elinye icala lomzimba wepleyiti yokuqala kude ne-groove yokuqala idityaniswe ngokuthe ngqo kunye ne-rocker Umphezulu wangaphambili we-worktable unikezwa nge-groove yesithathu, i-rocker ifumaneka kwi-groove yesithathu, i-groove yokuqala inikwe i-plate plate. , elinye icala leplate yokukhawulela kude kude negroove yokuqala lidityaniswe ngokusisigxina kunye nokuthwala, indawo yangasemva ye-worktable inikezelwa nge-threaded ngokusebenzisa umngxuma, kwaye i-screw rod idibaniswe nentambo kwi-threaded ngokusebenzisa umngxuma.

Njengokulungiswa ngakumbi kwesikimu sobugcisa, i-groove yesine icwangciswe kwelinye icala letafile yokusebenzela, umzimba wepleyiti yesibini icwangciswe ngaphakathi kwitafile yokusebenza, amacala angaphambili nasemva komzimba wepleyiti yesibini adityaniswe ngokulinganayo kwaye adibeneyo kunye nesilayidi sesibini. , ibhloko yesibini ye-sliding i-slides kwi-groove yesine, kunye nomgangatho ophezulu womzimba weplate wesibini uhambelana ngokufanayo kwaye ugxininisekile kunye nepleyiti yokuxhasa.

Xa kuthelekiswa nobugcisa bangaphambili, imodeli eluncedo inezi ziphumo zilandelayo ziluncedo: emva kokuba umbhobho usikiwe, i-rocker ijikwa ngasemva, i-rocker ijikeleza kwi-groove yesithathu, kwaye i-rocker iqhubela umzimba weplate yokuqala ukujikeleza ukuze ipleyiti yokuqala. Umzimba utyibilika kumqolo wesibini kwibhloko yesilayidi sokuqala.Ngenxa yokuba umzimba weplate yokuqala usondele kwizinto zombhobho, xa umzimba weplate yokuqala ujikeleza, unokuqhuba umbhobho ukuba uqhubele phambili Emva kokuba umbhobho unqunyulwe, akuyimfuneko ukuba abasebenzi bahambe ukukhuthaza ukwenzeka kwezinto zombhobho, egcina ixesha kunye nomgudu, kwaye ilungele ukusika umbhobho.

Enye inkalo yokuba abaqalayo bahlala besenza iimpazamo kwi-hose yokuluka kukusika.Nje ukuba i-braid iqale ukunxiba, phantse akunakwenzeka ukujongana nayo, ikukhathaza kwaye ukopha iminwe yakho.Ungathethi, akunakwenzeka ukubeka izixhobo kwi-hose egqitywe kwiiphelo zombini.

Nantoni na oyenzayo, musa ukusebenzisa i-hacksaw.Esi sesona sixhobo sibi kakhulu sokusika i-hose ephothiweyo.Kukho iintlobo ezintathu zezixhobo zokusika, enye isarha, enye isarha.

yenza amalungiselelo

Kufuneka ulungiselele ngaphambi kokuba unqumle ithumbu.Gquba i-intshi ezimbalwa ze-hose ngetape yombane okanye i-masking tape.Emva koko zoba umgca wakho wokusika kwiteyiphu.I-tape iya kunceda ukukhusela i-braid ye-braid ngexesha lokusika kunye nokudibanisa.Ukusonga umbhobho ngeteyiphu kunceda ukuthintela ukuguga kuzo zombini iziphelo kwaye kukubonelela ngendawo ecocekileyo yokumakisha ukusikwa.

Iinketho zokusika

Iisarha zebhendi ayilona khetho lungcono, kodwa ukuba uthatha ixesha lakho, unako.Kufuneka uhambe kancinane, kwaye ekugqibeleni, njengokuba udlula elaphini, qengqeleka kancinane ithumbu kwincakuba yesarha ukuze ungafumani naziphi na iingcingo ezigugileyo.Yindlela efanelekileyo yokunqumla i-hose ngevili lokusika, kwaye umsebenzi unokugqitywa ngaphandle kweengxaki ezininzi.Unokubamba i-hose ngesandla esinye kwaye uyinqumle ngesinye, kodwa kungcono ukusebenzisa i-vise ukuze ube nolawulo olungcono kwivili lokusika.Hamba kancinci.Qaphela ukuba ungafaki uxinzelelo oluninzi kwi-hose, okanye iya kubangela ukuguga.Ivili elisikiweyo lisebenza ngokufanelekileyo, unokunqumla i-hose phantsi kwemoto iyimfuneko.Thatha ixesha lakho.Thatha ixesha lakho.Thatha ixesha lakho.

Isixhobo esilungileyo sisisarha esinevili lokugaya.Uza kufumana ukusika okulungileyo, okucocekileyo ngaphandle kokugqoka kunye nokukrazula, kwaye i-chopper saw ine-fixture eyakhelwe-ngaphakathi, ngoko akufanele ukhathazeke ngokuphosa i-cut.Kungcono ukuba nesarha ebambe umbhobho endaweni ukuze ukwazi ukuyilawula ngokupheleleyo kwaye unokufumana ukusika okucocekileyo.

Olu hlobo lokunxiba luhlala lusenzeka, ngoko qaphela ukuba ungasikwa ngokukhawuleza.Ungazicheba ezi zinto ngeengcingo zokusika, kodwa kuyakhohlisa.

Emva kokuba i-hose inqunywe, faka i-hose eseleyo kwaye ushiye i-tape ekupheleni.Into ofuna ukuyisebenzisa kufuneka idityaniswe, esiza kuyigubungela kwelinye inqaku.Musa ukususa i-tape okwangoku, okanye iya kubangela ukuba ilaphu likhulule, into embi.
