Ukuqonda i-R Angle kuma-Square and Rectangular Steel Tubes

Izingxenye ezinezimbobo eziyisikwele nezingunxande zingase zibukeke zilula, kodwa imininingwane eminingi yobuchwepheshe ithinta amandla azo kanye nokusebenza kwazo. Esinye sezici ezinganakwa kakhulu kodwa ezibaluleke kakhulu yi-I-engeli engu-R, eyaziwa nangokuthi i-corner radius. Idlala indima enkulu ekwakheni ikhwalithi, ukuziphatha kokushisela, ukusebenza komthwalo, ukunamathela kokumboza, kanye nokubukeka okubonakalayo.

Lesi sihloko sichaza ukuthi iyini i-R angle, ukuthi izindinganiso ezinkulu ziyichaza kanjani, ukuthi ilinganiswa kanjani, nokuthi yini abathengi okufanele bayinake lapho bekhetha amashubhu.

Iyini i-R Angle?

I-angle ye-R ibhekisela ku-irediyasi ye-arc yangaphandle yekonayensimbi eyisikwele noma engunxandeipayipi.
Esikhundleni somphetho obukhali wama-degree angu-90, ikona lenziwa libe yigobe eliyindilinga ngesikhathi sokubumba noma ukukhipha.

Kuthinta:

Ukusebenza kwesakhiwo

Ukushibilika

Ubuhle

Ukusatshalaliswa kobukhulu bokumboza

Ukufakwa kokuxhumeka kanye nokulawula ukubekezelelana

Nakuba kubonakala kuncane, i-radius ekhoneni engafanele ingathonya ngqo imiphumela yobunjiniyela.

Izidingo ze-R Angle Ngaphansi Kwezindinganiso Ezivamile Zezimboni

Izifunda nezindinganiso ezahlukene zichaza ukubekezelelana kwe-R ngendlela ehlukile.
Nasi ireferensi elula:

◎ Izinga lesiShayina (GB/T 3094, GB/T 6728)

Irediyasi yekona ivame ukuba phakathiUbukhulu bodonga obuyi-1.5 × kuya ku-3 × ubukhulu bodonga

Ezinye izinhlelo zokusebenza zivumelaubuncane be-R ≥ 2mm

◎ I-European Standard EN10210 (Eyenziwe Ngokushisayo)

Ukubekezelela ukujiya kodonga okuphezulu kanye nerediyasi enkulu

I-engeli ejwayelekile ye-R ≈2 × ubukhulu bodonga, kodwa ingafinyelela2.5 × noma 3 ×kwezingxenye ezinkulu

◎ EN10219 (Yakhiwe Ngobandayo)

Irediyasi encane uma iqhathaniswa ne-EN10210

I-R evamile ≥Ubukhulu bodonga obungu-1.5 ×

◎ I-British Standard BS EN10219 / BS 4360

Ihambisana eduze nezidingo ze-EN10219

Igxila kakhulu ekuqineni kwesimo sekhoneni kanye nemikhawulo yokuphambuka

◎ I-JIS G3466 ejwayelekile yesiJapane

Ichaza i-R angle njengokuzungezaUbukhulu bodonga obungu-1.2 × kuya ku-2.0 ×

Yaziwa ngokulawula okuqinile kobukhulu

✔ In izinhlelo zokusebenza zangempela, irediyasi yekona ayilungisiwe; iyahlukahlukaokusekelweon iubuchwepheshe bokwakha, amathuluziubukhulu, futhi okuhloswesebenzisa.
✔ Ukukhiqizaukubekezelelana ngokuvamileziyahlukahluka phakathi kwezinhlobo ezahlukeneumhlinzekis.

Indlela Yokubhekisela Nendlela Yokulinganisa Ifomula

Ifomula Yokulinganisa I-R Angle (Umthetho Wesithupha Wemboni):

R ≈ 1.5–3.0 × ubukhulu bodonga (t)

Isibonelo:
Uma ubukhulu bodonga bungu-5mm → i-engeli engu-R ≈ 7.5mm–15mm

Indlela Yokulinganisa Insimu

I-angle ye-R ingahlolwa yi:

✔ Amathuluzi okulinganisa i-Radius
✔ Izifanekiso zokulinganisa indilinga
✔ Umshini wokulinganisa iphrofayili

Izinyathelo:

Beka igeyiji noma ithempulethi ekhoneni lethubhu

Qondanisa i-arc yokulinganisa

Funda inani noma ukubekezelela ukufaneleka kwerekhodi

Qhathanisa nesidingo esijwayelekile noma se-oda

Amaphrojekthi amakhulu ngezinye izikhathi asebenzisa ukuskena kwe-3D noma i-CMM ukuqinisekisa ukunemba kwejometri.

Kungani i-R Angle Ibalulekile?

Irediyasi yekona ithinta:

✔ Amandla — kunciphisa ukugxilisa ingqondo ekucindezelekeni
✔ Ukwemboza — kuqinisekisa ukumbozwa kwe-galvanizing emaphethelweni
✔ Ukushisela — kuthuthukisa ikhwalithi yokuhlanganiswa
✔ Ubuhle — ukubukeka okubushelelezi
✔ Ukuhlanganiswa — kuthinta ukulingana kwesikhala kanye nosayizi wesixhumi

Kumapayipi esikwele anodonga olujiyile noma izinhlelo zokusebenza zesakhiwo,ithini le-R engeli elingalungileokuyimbangela yeizikhala, izinkinga zokushisela, noma izingozi zokukhathala ezifihliwe.

Okufanele Uhlole Lapho Uthenga Insimbi Ngezidingo Ze-R Angle

Abathengi kufanele bahlole:

① Qinisekisa Ukuthobela Imithetho Ejwayelekile

Buza umhlinzeki ukuthi iyiphi inqubo yokwakha kanye nezinga abalilandelayo
(EN10210, EN10219, GB, JIS, BS zinezimo ezihlukene zamakhona).

② Qinisekisa ukuthi i-Radius ihlangabezana nezidingo zesicelo

U-R omkhulu → ukumbozwa okubushelelezi, okuqinile, okulula

I-R encane → imiphetho ebukhali, ifanelana kahle nezixhumi

③ Hlola Ubukhulu Bodonga Nokufaniswa Kwe-R

Irediyasi yekona ilingana nobukhulu bodonga—irediyasi encane kakhulu yamapayipi amakhulu ivame ukubonisa ukwakheka okungafanele.

④ Qinisekisa Ukulinganisa Kwangempela

Isicelo:

Idatha yokuhlola i-Radius gauge

Izithombe ezisikiwe ekugcineni

Ishidi lokuhlola elinobukhulu

⑤ Naka Ukucutshungulwa Ngemva Kokucutshungulwa

Ukugalela nge-hot dip galvanizing, ukubhoboza, noma ukukhanda kudinga irediyasi ekhoneni efanelekile ukuze kugeleze ukumboza kanye nokuqina kwesakhiwo.

Isiphetho

I-R angle akuyona imininingwane yobuhle.
Kuthinta ukwakha ikhwalithi, ukusebenza komthwalo,impilo yesevisi, kanye nokunemba kokufakwa.

Ukuqonda ukuthi amazinga ahlukene achaza kanjani i-engela yekona—nokwazi ukuthi ungayilinganisa futhi uyihlole kanjani—kusiza ukuqinisekisa ukukhethwa kwezinto ezifanele kanye nemiphumela yobunjiniyela ethembekile.
