Izinto ezibalulekileyo ekufuneka ziqwalaselwe

• Ukusika okusekelwe kubunzima kubamba into engenakukwazi ukusikwa okusekelwe kubude: uxinano oludityanisiweyo kunye nobukhulu bephepha buyahluka, ngoko ke ubude obulinganayo abufane buvelise ubunzima obulinganayo.
• Umatshini wokusika ubunzima ozenzekelayo we-XCJ-A 600 udibanisa i-LASCAUX weight sensor enolawulo lwe-Delta PLC, usika ngendlela elungele umsebenzisi kwaye uhlela yonke into ngokuzenzekelayo.
• Ukusika ii-preforms ukuya kwifestile eqinileyo (umzekelo ±0.3 g) kunciphisa inkunkuma yezinto ezigqithisileyo kunye neengcola zokubumba ezingaphantsi kobunzima ngaxeshanye.
• Beka iziqwenga ekujoliswe kuzo ngesikhunta ngasinye (6 okanye 10) kwisikrini sokuchukumisa kwaye umatshini wondla inani elichanekileyo, ususa ukubalwa ngesandla kunye nokuphathwa kabini.

Ii-O-rings zezona zinto zisetyenziswa kakhulu ekutywineni irabha, kwaye yonke i-O-ring ebunjiweyo ithwala i-flash kumgca wayo wokuhlukana. Ukukhethwa komatshini wokunyibilikisa i-O-ring akuchaphazeli kuphela inkangeleko yobuhle be-O-ring kodwa nokusebenza kwayo ekutywineni, ukuhambelana kwayo, kunye neendleko zemveliso. Esi sikhokelo sibonelela ngesakhelo esilinganisiweyo sokufanisa izixhobo zokunyibilikisa i-O-ring kunye neeparamitha zemveliso ye-O-ring.

Iimfuneko zokuCima ii-O-Ring: Yintoni eyenza zahluke kwezinye iindawo zerabha

Ii-O-rings zinemingeni emininzi yokukhuhla inkunkuma engabonakaliyo kwezinye iimveliso zerabha. Ngenxa yokuba isikhunta esinye se-O-ring sivelisa amashumi okanye amakhulu eembobo, i-parting line flash ihamba kububanzi bangaphakathi kunye nobubanzi bangaphandle bendandatho nganye. I-cross-section encinci — ii-cross-sections eziqhelekileyo ze-O-ring ziqala kwi-1.5 mm ukuya kwi-8.4 mm nganyeI-ISO 3601-1— kuthetha ukuba ifleshi ikufutshane nomphezulu wokuvala osebenzayo. Nakuphi na ukukhuculula kakhulu okususa izinto ezisisiseko kwindawo apho ifleshi idibana khona kudala indlela yokuvuza engenakubonwa ngokuhlolwa okubonakalayo kuphela.

Ngaphezu koko, ii-O-rings zihlulwe phantsiI-ASTM D1414kwiindlela zovavanyo ezisemgangathweni, ezichaza iinkqubo zokuqinisekisa ubukhulu apho ukucocwa kwe-deflashing akufuneki kube yingozi.I-ISO 3302-1, ukunyamezelana kobukhulu beeringi ze-O ezichanekileyo kususela kwi-±0.08 mm kwiindawo ezinqamlezileyo ezingaphantsi kwe-2.5 mm ukuya kwi-±0.22 mm kwiindawo ezinqamlezileyo ezingaphezu kwe-10 mm. Indlela yokukhuculula kufuneka isuse ifleshi ngaphandle kokutshintsha ezi milinganiselo zibalulekileyo.

Into engacacanga kangako kodwa ebaluleke ngokulinganayo yindawo apho i-flash ikhoyo. Ii-O-ring molds zihlala zinomgca wokuhlukana kwindawo ephakathi kwe-mold, oko kuthetha ukuba i-flash ihleli ngqo kububanzi be-seal. Ukucocwa okushiya intsalela engaphezulu kwe-0.1 mm kwi-ID okanye kwi-OD kudala isiphene sokutywina esibangela ukuvuza xa uxinzelelo lulinganisiwe. Lo mda wejometri wenza ukuba ukukhetha indlela yokucocwa kwe-O kubaluleke kakhulu kwii-O-rings kunakwiindawo zerabha ezimile ngendlela engaqhelekanga apho i-flash ingekho kumphezulu osebenzayo.

Izinto Ezintlanu Zokuthatha Izigqibo Zokukhetha Umatshini Wokucoca Irabha Wee-O-Rings

Inkalo 1: Uluhlu lobungakanani be-O-Ring kunye neCandelo eliQhelekileyo

Ubukhulu bomzimba bee-O-rings zakho bubeka umda wokuqala kwizixhobo. Oomatshini bokususa iidrama ngoomatshini basebenza ngaphakathi koluhlu oluchaziweyo lobubanzi.Umatshini wokucoca iidrama we-XCJ-G600, enobubanzi bayo bedrum obuyi-600 mm kunye nomthamo webhetshi eyi-15 kg, isebenza ngee-O-rings ukusuka kububanzi obuyi-3 mm ukuya kwi-100 mm. Ii-O-rings ezincinci kune-3 mm zivame ukudlula kwiimbobo zedrum okanye kwindlwane ngamaqela, nto leyo enciphisa ukusebenza kakuhle kokukhuhla. Ii-O-rings ezingaphezulu kwe-100 mm OD zifuna idrum enkulu okanye enye indlela yokuphatha.

I-cross-section nayo ibalulekile. Ii-O-rings ezincinci ezine-cross-sections ezingaphantsi kwe-2 mm zisengozini yokugoba kunye nokonakala komphezulu ngexesha lokuwa koomatshini. Kwezi, ukucubungula i-cryogenic lolona khetho lukhuselekileyo kuba irabha eqandisiweyo iziphatha njengezinto eziqinileyo xa ibetha kwi-media. Umgaqo osebenzayo esiwusebenzisayo kumzi-mveliso wethu:Iiringi ze-O ezine-cross-section ≥2.5 mm kunye ne-OD ephakathi kwe-8 mm kunye ne-80 mm zezona zifanelekileyo zokukhupha iidrama ngoomatshini, ngelixa iiringi ze-O ezingaphandle kolu luhlu kufuneka zihlolwe ukuze zisetyenziswe njenge-cryogenic.

Inkalo 2: Iprofayili yeFlash kunye nohlobo lwezinto

Ubukhulu beFlash yeyona parameter ibalulekileyo yenkqubo. Ukususwa kwe-mechanical deflashing kusebenza ngempumelelo xa umlinganiselo wobukhulu be-flash-to-part uyi-0.1 okanye ngaphezulu — oko kuthetha ukuba i-O-ring ye-cross-section eyi-3.5 mm ene-0.35 mm flash inokususwa ngoomatshini, ngelixa i-1.8 mm cross-section ene-0.15 mm flash ayinakukwazi. Kwii-O-rings ezibunjwe kwizixhobo eziphezulu apho i-flash ihlala i-0.1-0.3 mm, izinto ezisetyenzisiweyo zigqiba ukuba i-mechanical okanye i-cryogenic deflashing ifanelekile na.

Ubukhulu beFlash bulinganiswa kwindawo etyebileyo yomgca wokuhlukana kwesikhunta. Amaxabiso okwenyani anokwahluka ngokwendlela exutyiweyo kunye nemeko yesikhunta.

Ingongoma 3: Ubungakanani bemveliso kunye nobungakanani bebhetshi

I-XCJ-G600 icubungula ibhetshi ye-O-rings enobunzima be-15 kg kwimizuzwana engama-20-40 ngomjikelo ngamnye. Ngobunzima obuqhelekileyo be-O-ring obuyi-2-10 grams kuxhomekeke kubukhulu, ibhetshi enye inee-O-rings eziyi-1,500-7,500. Kwimizuzwana engama-40 ngebhetshi nganye enomthwalo kunye nokukhulula umthwalo ngaphezulu, isiphumo esisebenzayo simalunga neebhetshi ezingama-60-80 ngotshintsho lweeyure ezi-8, okanye ii-O-rings ezingama-90,000-600,000 ngotshintsho kuxhomekeke kubukhulu.

Imveliso ephezulu ngaphezu kwama-500,000 ee-O-rings ngosuku inokwenza ukuba kubekho umgca okhethekileyo we-cryogenic kwiisayizi ezincinci kunye nomgca we-mechanical kwiindidi eziphambili, kodwa kubavelisi abaninzi abaphakathi, umatshini omnye we-mechanical drum uphatha i-80-90% yepotifoliyo ye-O-ring.I-10-20% eseleyo — ngokuqhelekileyo i-silicone okanye i-sub-6 mm ID O-rings — ingathunyelwa ngaphandle okanye isebenze kumatshini omncinci we-cryogenic batch.

Inkalo 4: Iimfuno zoKunyamezela kunye noMgangatho

I-ISO 3302-1 ihlela ukunyamezelana kweemveliso zerabha kwiindidi ezine. Udidi A (ukuchaneka) lufuna ±0.08 mm kwiindawo ezinqamlezileyo ezingaphantsi kwe-2.5 mm. Udidi B (oluncinci) lufuna ±0.10 mm. Udidi C (oluphakathi) lufuna ±0.14 mm. Indlela yokukhupha umbane kufuneka ikwazi ukususa i-flash ngaphakathi kwebhendi yokunyamezelana ngaphandle kokunciphisa indawo enqamlezileyo ngaphantsi komlinganiselo ovumelekileyo. Ukukhupha umbane ngokukhetha imidiya efanelekileyo kufezekisa ukunyamezelana kweklasi B kunye no-C rhoqo. Ukukhupha umbane nge-cryogenic, ngokususwa kwayo kwezinto ezilawulwayo ngakumbi, kufezekisa ukunyamezelana kweklasi A kunye no-B kwii-O-rings ezineendawo ezinqamlezileyo ezincinci.Ukuba iinkcukacha zakho ze-O-ring zifuna ukuba i-Class A tolerances zibe ngaphantsi kwe-3 mm, i-cryogenic deflashing iyacetyiswa kakhulu.

Inkalo 5: Iindleko ezipheleleyo zokusebenza (i-TCO)

Izinto ezimbini ezixabisa kakhulu zihlala zingathathelwa ngqalelo ekukhetheni umatshini wokucoca: ukusetyenziswa kwemidiya kunye nokuhanjiswa kwe-nitrogen engamanzi. Ukucoca ngoomatshini kudla i-tumbling media (iiplastiki okanye ii-walnut shell pellets) ezifuna ukutshintshwa rhoqo. Ukucoca ngoxinzelelo lwe-cryogenic kudla i-nitrogen engamanzi kwi-0.5-2.5 kg nge-kg yerabha elungisiweyo, kuxhomekeke kubunzima kunye noxinano lwenxalenye.

Iindleko ezisekelwe kuqikelelo lwekota yesi-2 ka-2026 lwezixhobo ezisebenza eTshayina. Amaxabiso e-LN2 ayahluka ngokwengingqi; ukuhanjiswa ngobuninzi kunciphisa iindleko nge-15-25%.

Isakhelo seSigqibo: Ngowuphi umatshini wokucoca irabha wee-O-Rings ofanela imveliso yakho?

Abavelisi abaninzi basebenzisa indlela exutyiweyo: umatshini wokucoca iidrama oomatshini we-XCJ-G600 uphatha imveliso ephambili ye-NBR kunye ne-EPDM, ngelixa umatshini omncinci we-cryogenic ucubungula ii-silicone kunye nee-FKM O-rings ezimele i-10-20% yomxube wemveliso. Olu lungiselelo luphucula ukuveliswa kwezinto eziqhelekileyo ngelixa lugcina umgangatho kwiikhompawundi ezikhethekileyo.

Isiphelo: Tshatisa umatshini wokucofa inkunkuma kwipotifoliyo yakho ye-O-Ring

Akukho matshini umnye ongcono wokucoca irabha kwiiringi ze-O. Ukhetho oluchanekileyo luxhomekeke kubukhulu beringi ye-O, uhlobo lwezinto, imeko yefleshi, ubungakanani bemveliso, kunye neemfuno zokunyamezela. Ukucoca idrama ngoomatshini nge-XCJ-G600 sesona sisombululo singabizi kakhulu kwiiringi ze-NBR kunye ne-EPDM O ezisemgangathweni kuluhlu lwe-6-90 mm OD, zibonelela ngamaxesha omjikelo wemizuzwana engama-20-40 kwi-15 kg ngebhetshi nganye. Ukucoca i-cryogenic kuba yimfuneko kwiiringi ze-silicone kunye ne-FKM O, ii-ID ezincinci ezingaphantsi kwe-6 mm, kunye nezicelo zokunyamezelana okuchanekileyo kweKlasi A. Kwizixhobo zemveliso ezixutyiweyo, ukusebenzisa zombini ezi ndlela ngaxeshanye kwandisa ukuguquguquka ngaphandle kokubeka emngciphekweni ukusebenza kakuhle kweendleko kwizixhobo ezisemgangathweni eziphezulu.
