Izikhonkwane zeRoll vs. Izikhonkwane zeDowel: Ukukhetha i-Pin eLungileyo yoLungelelwaniso oluchanekileyo
Yintoni i-Roll Pin?
Aiphini lokuqengqelekais a slotted, cylinder hollow eyenziwe ngentsimbi yasentwasahlobo. Uyilo lwayo lukuvumela ukuba ucinezele i-pin radially ngexesha lofakelo, udala ukulungelelana kokuphazamiseka okuchasayo ukukhulula phantsi kwe-vibration. Iimpawu eziphambili:
-
Intshukumo yasentwasahlobo:I-slot ivumela i-pin ukuba iguquke kwaye ilume kwiindonga zomngxuma, yenza izikhonkwane zomqulu zilungele izicelo ezinemithwalo eguquguqukayo.
-
Ufakelo olulula:Vele uqhube isikhonkwane kumngxunya ongaphantsi kancinci-akukho kuphinda kufuneke.
-
Iidayamitha eziguquguqukayo:Ifumaneka kuluhlu lweesayizi (ukusuka kwi-1 mm ukuya kwi-20 mm +), izikhonkwane ze-roll zilungelelanisa kwi-shaft eyahlukeneyo okanye ubukhulu be-flange.
Ngenxa yokuziphatha kwabo okufana nentwasahlobo,izikhonkwane zasentwasahloboUkugqwesa kwiindawo ezingcangcazela kakhulu-cinga izigqubuthelo zebhokisi yegiya, iindibano ze-axle, kunye neehabhu zokudibanisa.
Yintoni iPin yeDowel?
Ngokwahlukileyo, aiphini yedowelyintonga eyomeleleyo, ebekwe ngokuthe ngqo emhlabeni, edla ngokwenziwa ngentsimbi engatyiwa okanye eqinisiweyo. Idayamitha yayo yangaphandle egudileyo, echanekileyo iqinisekisa indawo ephindaphindwayo:
-
Ukunyamezela okuqinileyo:Ubume obuqhelekileyo ngaphakathi kwe-0.01 mm kunye nokunyamezela kwedayamitha ye-±0.005 mm.
-
Amandla okucheba ngokuthe tye:Igqwesileyo ngokuthwala imithwalo yokucheba okanye ukugcina ubhaliso phakathi kwamacandelo okukhwelana.
-
Ukuchasa umhlwa:Izikhonkwane zedowuli zensimbi ezingenasici zisebenza kakuhle kwindawo engaphandle okanye efumileyo.
Ngemisebenzi efuna kanyeizikhonkwane zokulungelelanisa ezichanekileyo, izikhonkwane zedowel zezona zikhethwayo xa ucoceko kunye nokuqina kubaluleke kakhulu.
I-Roll Pin vs. I-Dowel Pin: Iiyantlukwano eziphambili
| Uphawu | Iphini lokuqengqeleka (iPin yaseNtwasahlobo) | Dowel Pin |
|---|---|---|
| Ulwakhiwo | Umbhobho, ityhubhu yentsimbi | Intonga eqinileyo, intsimbi ephantsi |
| Uhlobo olulinganayo | Uphazamiseko (ukunyanzeliswa okuguquguqukayo kufanelekile) | Ukutshintsha okanye ukutyibilika kufanelekile (iqinile kodwa igudile) |
| Ukuxhathisa ukungcangcazela | Phezulu (izikhonkwane zitshixeke endaweni ngentshukumo yasentwasahlobo) | Iphakathi (inokukhulula phantsi kokungcangcazela okukhulu) |
| Ukuhlohla | I-Punch-in ngqo-akufuneki ukubuyisela kwakhona | Ifuna umngxuma owenziwe ngokutsha okanye ogrunjwe ngokuchanekileyo |
| Ukunyamezela (ububanzi) | ±0.1 mm | ±0.005 mm |
| Ukusebenziseka kwakhona | Ngokuqhelekileyo ukusetyenziswa kanye | Inokusetyenziswa kwakhona ukuba ayonakaliswanga |
Zisetyenziswa nini izikhonkwane zokuqengqeleka vs. Izikhonkwane zeDowel
-
Khetha Izikhonkwane Zokuqengqeleka Xa:
-
Udinga isisombululo esineendleko ezifanelekileyoi-pin fastenerskwiindibano zokungcangcazela okuphezulu.
-
Ukulungiswa komngxuma kufuneka kube kuncinci-ukulungele ukulungiswa kwendawo okanye ukuveliswa ngokukhawuleza.
-
Ukubhetyebhetye kancinci kwamkelekile okanye kuluncedo (umzekelo, ukudityaniswa kweeshafti ezingalungelelanisiweyo).
-
-
Khetha Izikhonkwane zeDowel Xa:
-
Iqinileulungelelwaniso oluchanekileyoiyafuneka phakathi kwamacandelo amabini, njengakwi-jig fixtures okanye iibhedi zomatshini we-CNC.
-
Imithwalo yokucheba ibalulekile, kwaye udinga ukomelela okuthe ngqo kokucheba.
-
Ufuna indawo enokuphinda isebenziseke kwiindibano ezithathiweyo zaza zadityaniswa kwakhona.
-
Iingcebiso ezisebenzayo zokuFakelo
-
Ukulungiselela umngxuma:
-
Ufakelo lwephini lokuqengqeleka:Gqoka umngxuma oyi-0.2–0.3 mm mncinci kunomlinganiselo oqhelekileyo wesikhonkwane ukwenzela ungenelelo olukhuselekileyo.
-
Ukufakela isikhonkwane sedoli:Khupha umngxuma ngaphakathi kokunyamezela (umzekelo, ukulingana kwe-H7) kwaye uthintele indawo yokungena ukunqanda umonakalo we-pin.
-
-
Ubuchule bokuqhuba:
-
Sebenzisa i-pin punch kunye nesando esilula kwizikhonkwane zokuqengqeleka ukunqanda ukugqwetheka kwephini.
-
Kwizikhonkwane zedowel, i-press okanye i-arbor iqinisekisa ukufakwa ngokuthe ngqo kwaye inqande ukugoba.
-
-
Ungqinelwano lweMathiriyeli:
-
Kwiindawo ezinobungozi okanye ezinetyuwa, khethaizikhonkwane zentsimbi engenasiciokanye izikhonkwane zomqulu.
-
Kwiindibano ezikhaphukhaphu, i-aluminiyam okanye izikhonkwane zedoweli zobhedu zinokunciphisa ubunzima ngokuchaneka okwamkelekileyo.

Malunga neFasto
Zombini izikhonkwane ze-roll kunye nezikhonkwane zedowel zidlala indima ebalulekileyoulungelelwaniso oluchanekileyo. Ukuba ukuxhathisa ukungcangcazela, ukufakwa ngokukhawuleza, kunye nokusebenza kakuhle kweendleko zizinto eziphambili kuwe,izikhonkwane zasentwasahlobo(izikhonkwane zokuqengqeleka) zihambisa ukusebenza okuthembekileyo. Xa ukuchaneka kwesikhundla kunye namandla okucheba kungaxoxiswana,izikhonkwane zedowelnika unyamezelo oluchanekileyo lomhlaba kwiimfuno zakho zendibano. Ukukhetha okulungileyoisiqhoboshi sokuqhoboshangaphambili konga ixesha, kunciphisa ukusebenza kwakhona, kwaye kuqinisekisa ukuba oomatshini bakho baqhuba kakuhle ixesha elide.
Okanye uFastus, Sisebenza ngokukhethekileyo kwimveliso kunye nokunikezelwa kwehlabathi jikelele kwe-fasteners eyakhelwe ukuqina kunye nomsebenzi-kuquka umgca opheleleyo we-bimetal screws kunye nezikhonkwane ezichanekileyo. Ngaphezulu kweminyaka engama-20 yamava, sigxile kumgangatho, ukuthembeka, kunye nezisombululo ezilungiselelwe iimeko zokwenyani ojongene nazo emhlabeni.
