Ibicuruzwa byo kubara kubibujijwe

Gutera inshinge ni ngombwa mu gukora gukora bigezweho, bitanga byose mubice byimodoka kubintu bya plastiki bya buri munsi. Amabwiriza yo kubara neza ahitamo iyi nzira, kubungabunga imikorere nubwiza. Muriyi nyandiko, uziga formulaire yingenzi kugirango uhitanye imbaraga, igitutu cyo gushika inshinge, nibindi byinshi, kugirango wongere ibikorwa byatewe no gushingwa.

Gutera inshinge

Gutera inshinge ni inzira igoye yishingikiriza ku kiganiro gifatika cyibice bitandukanye byamashini nibipimo. Kugira ngo dusobanukirwe niyi mboneza yubuhanga, ni ngombwa gusobanukirwa nibintu byingenzi birimo.

Gutera inshinge ibice by'imashini n'imikorere yabo

Ibice byibanze bya mashini yo gusiga ishushanyijemo ikubiyemo:

• Ishami rishinzwe inshinge: Ushinzwe gushonga no gutera ibikoresho bya plastike muburyo bwa mold.

• Igice cya Clamping: Ifashe ifuruye mugihe cyo gutera inshinge kandi ikoresha imbaraga zikenewe zishimangira kugirango wirinde kubumbangurutse igitutu.

• Mold: igizwe nigice bibiri (cavit na core) ikora imiterere yibicuruzwa byanyuma.

• Sisitemu yo kugenzura: kugenzura no gukurikirana inzira zose zibangamiwe, gukurikiranwa n'ubushobozi.

Buri gice gifite uruhare runini mubikorwa byonosoye neza kandi bigira ingaruka muburyo bwimiterere yibice byabumbwe.

Ibipimo by'ingenzi mu miterere

Kugirango ugere kubisubizo byiza, ni ngombwa gusobanukirwa no kugenzura ibipimo byingenzi bikurikira:

1. Imbaraga zishimangiwe: Imbaraga zisabwa kugirango ifunge ifungire mugihe cyo gutera inshinge, kubuza ibikoresho guhunga no kwemeza igice gikwiye.

2. Indwara yo gutera inshinge: Umuvuduko ukoreshwa kuri plastiki yashongeshejwe nkuko byatewe mu kayira kegeranye, bigira ingaruka ku muvuduko wo kuzuza no kugereranywa.

3. Inshinga nini: ingano yibikoresho bya pulasitike byatewe mubisambo bya mold mugihe cya buri cyiciro, kigena ingano nuburemere bwibicuruzwa byanyuma.

Ibindi bipimo byingenzi birimo kwihuta, gushonga gushonga, igihe gikonje, no gukomera. Buri kimwe muri ibyo bintu kigomba gukurikiranwa neza kandi gihindurwa kugirango cyemeze ibice bihamye, bihanitse.

Umubano hagati yimashini ibisobanuro nibisabwa

Guhitamo imashini yo kwisiga biterwa nibisabwa byihariye byumushinga wabumbaza. Ibintu ugomba gusuzuma bikubiyemo:

• Ingano ya Kurasa: Ubwinshi bwa plastike imashini irashobora kwinjiza muruziga rumwe.

• Imbaraga zishimangiwe: Ubushobozi bwimashini bwo gukomeza ifumbire ifunzwe munsi yigitutu gikenewe cyo gushinga inshinge.

• Indwara yo gutera inshinge: Umuvuduko ntarengwa Imashini irashobora kubyara kugirango yuzuze umwobo.

• Ibintu byumutekano bya 1.1 (1 + 10%) kugirango bisobanuke muburyo bwibintu nibibazo byo gutunganya

Iyi formula itanga inzira yihuse yo kugereranya imbaraga zisabwa zishingiye kubicuruzwa geometrie nibikoresho.

Formula ya explical 2 ku mbaraga

Ifishi ya kabiri ifatika yo gukomera gushingiye ku gitutu cyabumbamo ibikoresho hamwe n'ahantu hateganijwe ibicuruzwa:

Imbaraga zishimangiye (T) = Ibikoresho byo guhindura Ibicuruzwa Biteganijwe Gukoresha S (CM ^ 2) Ikintu cyumutekano (1 + 10%) = 350bar s (1 + 10% (1 + 10%)

Muri iyi formula:

• Umuvuduko wibikoresho ufatwa nka 350 bar (agaciro gasanzwe kuri plastike nyinshi)

• S ni agace kerekana ibicuruzwa muri cm ^ 2

• Ikintu cyumutekano cya 1.1 (1 + 10%) gikoreshwa kugirango ubaze impinduka

Iyi formula ni ingirakamaro cyane mugihe ibintu byihariye bifatika bitamenyekanye, nkuko bishingiye kumuvuduko rusange ucuruzwa agaciro.

Ingero hamwe nibisabwa

Reka dusuzume urugero kugirango tugaragaze uburyo bufatika bwa formulaire yo gusoza imbaraga. Dufate ko ufite ibicuruzwa bifite agace kateganijwe ka CM 500, kandi ukoresha abs plastike (kp = 0.6).

Ukoresheje formula ya 1:

Imbaraga za Clamping (T) = kp s (1 + 10%) = 0.6 500 1.1 = 330 t

Ukoresheje formulaical 2:

Imbaraga zishimangiye (T) = 350 s / 1000 (1 + 10%) = 350 500/1000 1.1 = 192.5 t

Muri uru rubanza, Formalical formulaical 1 itanga imbaraga za 330 t, mugihe Formalical formula 2 yerekana imbaraga zishimangiye 192.5 t.

Gutondekanya ubushobozi

Mu kwishinyagurira, guteretamo ubushobozi bigira uruhare runini muguhitamo imikorere nubwiza bwibikorwa. Reka dusuzume iki gitekerezo kandi twige kubara.

Gusobanukirwa Ubushobozi bwo gushushanya

Gucurangagura ubushobozi bivuga umubare wibikoresho bya pulasitike bishobora gushonga kandi bigabanijwe na sisitemu yo gutemba imiyoboro ya scraction na barrel mugihe runaka. Mubisanzwe bigaragarira muri garama kumasegonda (G / Amasegonda).

Akamaro ko guca ishinyamisha ubushobozi buriho ingaruka itaziguye kuri:

• Igipimo cy'umusaruro

• Guhuza ibintu

• Igice cyiza

Ubushobozi budahagije bushobora kuganisha ku kuzenguruka ibihe byinshi, kuvanga nabi, no guhuza ibice. Ku rundi ruhande, ubushobozi bwo guca ishinyarurwa bukabije birashobora kuvamo gutesha agaciro ibintu no kongera ingufu.

Nigute ushobora kubara ubushobozi bwo gushinga amashanyarazi?

Ubushobozi bwo gushinga amashini yashizwemo burashobora kubarwa ukoresheje formula ikurikira:

W (g / sec) = 2.5 × (D / 2.54) ^ 2 × (H / 2.54) × 1000/3600/2

Aho:

• W: Ubushobozi bwa plastiki (g / sec)

• D: Diameter (cm)

• H: Umuyoboro wimbitse kuruhande rwimbere (cm)

• N: yatsinze umuvuduko wo kuzunguruka (rpm)

• S: Ubucucike bwibintu

Kugirango ukoreshe iyi formula, uzakenera kumenya geometriry ya screw (diameter numuyoboro wimbitse), umuvuduko wa screl, hamwe nubucucike bwibikoresho bya plastike bitungwa.

Reka dusuzume urugero rwo kwerekana inzira yo kubara. Dufate ko ufite imashini ishinyagurira hamwe nibisobanuro bikurikira:

• Imiyoboro ya diameter (d): cm 6

• Umuyoboro wa Screw wimbitse kuruhande rwimbere (H): 0,8 cm

• Yatsinze umuvuduko wo kuzunguruka (n): 120 rpm

• Ubucucike bwibikoresho Bwenze: 1.05 G / CM ^ 3

Gucoma izi ndangagaciro muri formula:

W = 2.5 × (6 / 2.54) ^ 2 × (0.8 / 2.54) × 120 × 1.05 × 1000/3600/2

W = 2.5 × 5.57 × 0.31 × 120 × 1.05 × 0.139

W = 7.59 g / sec

Muri uru rugero, uburyo bwo gutondeka bwo gusiga imashini bubindwa ni garama zigera kuri 7.59 kumasegonda.

Gusaba no gutekereza

Mugihe ushyiramo ibice byo kubanga kugirango ugabanye ibintu byisi-yisi, ibintu byinshi bigomba kwitabwaho kugirango tumenye ibisubizo byiza. Reka dusuzume ibyo bitekerezo turebe uko bigira ingaruka kumahitamo yashizweho kubicuruzwa byihariye.

Ibintu ugomba gusuzuma

Kugirango ugere ku gice cyifuzwa no gukora neza, ni ngombwa gusuzuma ibipimo byingenzi bikurikira:

1. Imbaraga Zishimangisho:

• Kugena ubushobozi bwo gukomeza ifuru mugihe inshinge

• Ingaruka Igice cyukuri kandi kikabuza flash

2. IHURIRO RY'INGENDO:

• Bigira ingaruka kumuvuduko wo kuzuza no gupakira umwobo

• Ingaruka igice cyubusa, hejuru hejuru, no gushikama

3. Inshinge nini:

• Kugena Ingano ya Shoti nigipimo ntarengwa cyigice gishobora gukorwa

• Ingaruka Guhitamo Imashini ikwiye

4. Umuvuduko wo gutesha agaciro:

• Bigira ingaruka kumiterere yo kuzuza, igipimo cyinkombe, hamwe nimyitwarire yibintu

• Bigira ingaruka ku isura, imitungo ya mashini, nigihe cyizuba

Mugusesengura witonze ibyo bintu no gukoresha formulaire ikwiye, gutera inzitirwa zirashobora guhitamo inzira y'ibipimo hanyuma uhitemo imashini ibereye kuri porogaramu yatanzwe.

Guhuza imashini ibisobanuro kubisabwa ibicuruzwa

Kugaragaza akamaro ko guhuza ibisobanuro kubisabwa nibicuruzwa, reka dusuzume ubushakashatsi buke:

Kwiga Urubanza 1: Imbere yinyuma

• Ibikoresho: Abs

• Igice gipimo: 250 x 150 x 50 mm

• Urukuta rw'urwango: 2.5 mm

• Imbaraga zisabwa: Toni 150

• Inshinge ingano: 150 cm ^ 3

Muri iki kibazo, imashini ishinyagurira ifite imbaraga zibura byibura toni 150 hamwe nubushobozi bwimibare ya cm 150 cyangwa irenga byaba byiza. Imashini igomba kandi kugira ubushobozi bwo kubungabunga igitutu gisabwa ninteruro hamwe numuvuduko mubikoresho bya ABS.

Ubushakashatsi bwa 2: Ibikoresho byo kwibitangaza

• Ibikoresho: PC

• Igice gipimo: 50 x 30 x 10 mm

• Urukuta rw'urwango: 1.2 mm

• Imbaraga zishimangira imbaraga: toni 30

• Inshinge Umubumbe: 10 cm ^ 3

Kuri iki gikoresho cyibikoresho byubuvuzi, imashini ntoya yangiza imashini ifite ubukonje bwo hejuru ya toni 30 hamwe nubushobozi bwo gutera inshinge bwa cm 10 ^ 3 byaba bikwiye. Imashini igomba kugira neza hejuru yigitutu nu muvuduko kugirango umenye neza ko Ubwuzuzanye n'ubwiza busabwa mu buvuzi.

Urubanza rwo Kwiga	Ibipimo	(MM)	Ubunini bwa Wall (MM)	bisabwa guhahira (tons)	inshinge (cm ^ 3)
1	ABS	250 x 150 x 50	2.5	150	150
2	Pc	50 x 30 x 10	1.2	30	10

Umwanzuro

Muri iki kiganiro, twashakishije imiterere yinshi. Kubara neza kungufu, igitutu cyo gutera inshinge, n'umuvuduko ni ngombwa. Iyi formulaire yemeza neza kandi ireme ryibicuruzwa.

Gukoresha formulaire neza ifasha guhitamo inzira yo gutemba. Kubara neza birinda inenge no kunoza imikorere yumusaruro.

Buri gihe ukoreshe iyi fomulare witonze. Nubikora, uzagera kubisubizo byiza mubikorwa byawe byo gushingwa.
