Ingabe i-Rebar Bender engu-40mm ingagoba ngempela njalo nge-Bar engu-40mm?
Uma uqala ukubheka, impendulo ibonakala isobala. Uma umshini uthengiswa njenge- rebar bender engu-40mm , kufanele ugobe i-40mm bar. Empeleni, lokho kucabanga kungafaka abathengi enkingeni. Ububanzi obuphrintiwe ephepheni lokucacisa ngokuvamile bubhekisela ezintweni ezithile kanye nesimo sokuhlola. Shintsha ibanga lensimbi, uhlobo lwe-bar noma i-geometry yokugoba, futhi amandla angasetshenziswa nawo angashintsha. Yingakho imigoqo emibili elingana ngqo no-40mm ububanzi ingase ingabi nesidingo esifanayo emshinini wokugoba i-rebar .
Sekuvele kunemininingwane eminingi yangempela yomshini ekhombisa umehluko. I-bender eyodwa yokuhweba engu-40mm ilinganiselwe ukuqinisa okungu-40mm Grade 240 kodwa i-32mm Grade 400 bar kuphela. Lokho kungukunciphisa okungu-20% kobubanzi obuvumelekile ngaphandle kokushintsha umshini uqobo. Insimbi yashintsha; amandla asebenzayo ashintsha ngayo.
Isilinganiso esingu-40mm siwusizo, kodwa kufanele siphathwe njengesiqalo sokuhlola imininingwane kunokuba siphathwe njengokuphela kwaso. Abathengi kufanele bahlale bebuza ukuthi lesi sibalo sibhekisela kuluphi uhlobo lwezinto. Ingabe yinsimbi eyindilinga engenalutho? Ukuqina okushintshile? Yiliphi izinga lensimbi elisetshenzisiwe?
Isibonelo, i-CAMCO ibala umshini owodwa we-GW40 onobubanzi bokugoba obungu-6–40mm kubha evamile eyindilinga, kuyilapho ibha eguquliwe yeBanga lesi-2 inqunyelwe ku-6–32mm. Lowo mehluko ongu-8mm ubalulekile. Umthengi ofunda kuphela isibalo esikhulu "esingama-40mm" angacabanga kalula ikhono elingathembisi incazelo eningiliziwe.
| Isibonelo Esishicilelwe | Ububanzi obukhulu | Lokho Okukubonisayo |
|---|---|---|
| Ukuqinisa kwebanga lama-240 | 40mm | Insimbi enamandla aphansi ifinyelela esiphezulu esinqunyiwe |
| Ukuqinisa kwebanga lama-400 | 32mm | Izinga lensimbi ephezulu linciphisa ububanzi obusebenzisekayo |
| Ibha eyindilinga evamile | 40mm | Insimbi eyindilinga ingaba namandla aphezulu okushicilelwa |
| Ibha ekhubazekile yeBanga lesi-II | 32mm | Ukuqina okukhubazekile kungaba nomkhawulo ophansi |
Ngakho-ke uma umhlinzeki ethi, “Lo mshini ugoba insimbi engu-40mm,” okulandelayo okunengqondo kumane nje: “Yiyiphi insimbi engu-40mm?” Lowo mbuzo owodwa ungasindisa izingxoxo eziningi ezixakile ngemva kokuba umshini ufikile endaweni.
Ububanzi bukutshela ukuthi ibha inkulu kangakanani, kodwa abukutsheli ukuthi izinto zimelana kangakanani nokuguquguquka. Ukuqinisa amandla aphezulu ngokuvamile kudinga umzamo owengeziwe ukuze kwakheke, yingakho abakhiqizi abaningi benikeza imikhawulo yamandla ahlukene ngamamaki ahlukene.
Isibonelo esiwusizo sivela ekucacisweni kwe-TMG kagesi ye-rebar bender eshicilelwe. Umshini ulinganiselwe ukuqinisa okungu-40mm Grade 240 kodwa kungu-32mm Grade 400 kuphela. Imodeli efanayo inikeza nobubanzi bokugoba obungu-0–180°, ukunemba kwe-engeli okuchazwe ngu-±1° kanye nesivinini sediski esiphakathi kuka-5 no-10rpm. Lezo zibalo zenza ukucaciswa kube wusizo kakhulu kunelebula elula ethi “ubukhulu obungu-40mm” ngoba zitshela umthengi okuthile mayelana nomthamo kanye nokulawula.
Kwabakhi bezindlu kanye nezitolo zokukhiqiza ama-rebar, isifundo silula: fanisa umshini nesheduli yangempela yokuqinisa. Uma iphrojekthi isebenzisa kakhulu ibha enamandla aphezulu, ububanzi obukhulu obukhangisiwe kungenzeka bungabi ububanzi okufanele ubusebenzise ekukhetheni umshini.
Lokhu kungenye indlela evamile yokudideka. Amanye amakhathalogi asebenzisa inkulumo ethi “umthamo wokugoba kwebha yensimbi”, kuyilapho iphrojekthi ngokwayo isebenzisa ukuqinisa okukhubazekile. Lokho akuzona njalo izilinganiso ezilinganayo.
Umshini ungaphatha kahle ibha eyindilinga engu-40mm futhi ube nomkhawulo ophansi oshicilelwe we-rebar eguquliwe. Umehluko ungavela ebangeni lensimbi nendlela umshini olinganiswe ngayo. Yingakho amaqembu okuthenga kufanele afune amagama aqondile kulokho okushiwoyo esikhundleni sokuthembela egameni lomkhiqizo kuphela.
Ngamanye amazwi, “ibha yensimbi engu-40mm” kanye “nebha yokuqinisa engu-40mm” kungase kuzwakale kufana kakhulu encwajaneni, kodwa kubhokisi lamagiya kungaba amakhasimende ahluke kakhulu.
Amandla ayingxenye nje yomsebenzi. Ibha kufanele futhi igotshwe eduze kwe-former noma i-mandrel efanele. Ukugoba okuqinile kakhulu kwandisa ukucindezeleka kwendawo ensimbini, ngakho-ke izindinganiso zokuqinisa zibeka imingcele ku-geometry yokugoba kunokuvumela ibha ukuthi igoqwe noma yini eyenzeka ukuze ilingane nomshini.
Isiqondiso esinemininingwane se-Eurocode 2 sisebenzisa ububanzi obuyisisekelo obuncane be-mandrel obuphindwe kane kunobubanzi bebha ukuze kuqiniswe kuze kufike ku-16mm kanye nobubanzi bebha obuphindwe kasikhombisa kunobubanzi bebha ukuze kuhlolwe umonakalo wokuqinisa. Ku-40mm bar, i-7 × 40mm inikeza ububanzi be-mandrel obungu- 280mm ngaphambi kokuba kucatshangelwe noma yikuphi ukuhlolwa okwengeziwe kwephrojekthi ethile.
Lelo nani lifanele ukukhunjulwa. Umshini ungaba ne-torque eyanele yokuhambisa ibha engu-40mm kodwa ungafaneleki ukugoba okudingekayo uma kungekho amathuluzi afanele. Lapho ukhetha umshini wokugoba we-rebar ongu-40mm , amaphini, ama-rollers kanye nama-formers adinga ukunakwa okucishe kufane namandla enjini.
Umsebenzi wokukhiqiza wengeza olunye ungqimba embuzweni womthamo. Amayadi okukhiqiza avame ukugoba imigoqo eminingana emjikelezweni ofanayo, ngakho-ke umkhawulo webha eyodwa awusho yonke indaba.
Umshini owodwa we-B55-S othengiswa e-UK unqunyelwe ibha eyodwa engu-40mm, imigoqo emibili engu-32mm noma imigoqo emithathu engu-25mm. Usebenzisa injini enezigaba ezintathu engu-5.5kW futhi unesivinini sokugoba esishicilelwe esingu-6rpm. Leyo yindlela ewusizo kakhulu yokuchaza amandla okusebenza ngoba ikhombisa ukuthi umshini uziphatha kanjani ngaphansi kwezinhlanganisela ezahlukene zebha.
| Ukuhlelwa Kokugoba | Amandla Okushicilelwe |
|---|---|
| Ibha eyodwa | 1 × 40mm |
| Amabha amabili | 2 × 32mm |
| Amabha amathathu | 3 × 25mm |
| Injini | 5.5kW |
| Isivinini sokugoba | 6rpm |
Endaweni egoba kakhulu ngezikhathi ezithile, ububanzi obukhulu bungaba yinto ebaluleke kakhulu. Endaweni yokusebenzela ekhiqiza amakheji usuku lonke, isivinini somjikelezo, ukuphindaphindwa kanye nomthamo wamabha amaningi ngokushesha kuba yinto ebaluleke ngokufanayo.
Indlela ephephile ukuqala ngesheduli yensimbi kunekhathalogi yomshini. Bhala phansi ububanzi bebha obukhulu kunabo bonke, izinga lensimbi, osayizi bebha abavamile abasetshenziswa nsuku zonke, ama-engeli okugoba adingekayo kanye nobubanzi bokugoba. Bese ubheka ukuthi imigoqo emikhulu ibonakala kangaki ekukhiqizweni.
Uma ukuqinisa okungu-40mm kusetshenziswa ngezikhathi ezithile kuphela futhi umsebenzi omningi wansuku zonke usebangeni elingu-16–25mm, i-rebar bender elinganiswe kahle engu-40mm ingaba yinto efanele. Uma i-bar enamandla aphezulu engu-40mm iyingxenye yokukhiqiza okuvamile kwansuku zonke, ukuthuthela ekilasini lomshini elikhulu kunganikeza opharetha isilinganiso esithe xaxa sokusebenza esikhundleni sokugcina umshini usezingeni eliphezulu lobubanzi bawo obushicilelwe usuku lonke.
I-voltage, ukucushwa kwenjini, isivinini sokugoba, amathuluzi, izingxenye ezisele kanye nokufinyelela kwesevisi kufanele kuhlolwe ngaphambi kokuthenga. Azijabulisi kakhulu kunenombolo enkulu yobubanzi ekhasini lokuqala, kodwa ngokuvamile zibaluleke kakhulu ngemva kwezinyanga eziyisithupha zomsebenzi wangempela.
