Kugwiritsa ntchito mfundo yodulira ndi kuwotcherera ya ultrasonic

Mfundo Yodulira ndi Kuwotcherera Ma Ultrasonic

Kudula ndi kuwotcherera kwa ma ultrasound ndi gawo laling'ono la ntchito za ma ultrasound m'makampani, ndipo lakhala likugwiritsidwa ntchito kwambiri chifukwa cha makhalidwe ake abwino, ogwira ntchito bwino, komanso okongola.

Mfundo yodulira ndi kuwotcherera ya akupanga

Kudula ndi kulumikiza ma webbing pogwiritsa ntchito makina othamanga kwambiri a 20-40kHz, kusamutsa mphamvu kupita pamwamba pa webbing kudzera mu mutu wolumikizira. 1. Kusintha kwa Mphamvu: Jenereta ya ultrasonic imasintha mphamvu zamagetsi kukhala makina othamanga kwambiri, zomwe zimakulitsidwa ndi transformer ya amplitude kenako zimatumizidwa ku mutu wolumikizira. 2. Kupanga Kutentha Kokangana: Mutu wolumikizira umakanikiza pa webbing, zomwe zimapangitsa kukangana kwakukulu pakati pa ulusi mkati mwa webbing, nthawi yomweyo kupanga kutentha kwakukulu kwa 500-1000℃. 3. Kulumikiza ndi Kudula Kogwirizana: Kutentha kwakukulu kumasungunula ulusi wa webbing (monga nayiloni ndi polyester), pomwe kuthamanga kwa mutu wolumikizira kumakhudza gawo losungunuka, ndikupanga gawo lolimba la weld. Ngati ligwiritsidwa ntchito ndi mutu wolumikizira wa m'mphepete mwapadera, kutentha kwakukulu kumatha kudula weld nthawi imodzi, ndikukwaniritsa "kudula + kulumikiza". 4. Kuziziritsa ndi Kupanga: Kuthamanga kukatha, kupanikizika kumasungidwa kwa masekondi 0.1-0.5, kulola malo olumikizira kuti azizire ndikulimba mwachangu, ndikumaliza njira yodulira ndi kulumikiza. (Makina a pneumatic amapereka ma cushion, komanso kuonetsetsa kuti kuziziritsa ndi kupanga mawonekedwe panthawi yodula ndi kuwotcherera.)

Kapangidwe ka makina odulira ndi kuwotcherera a ultrasonic

Dongosolo lolumikizira pulasitiki la ultrasonic lomwe limagwiritsidwa ntchito kwambiri limapangidwa ndi zigawo zitatu zazikulu: jenereta ya ultrasonic (bokosi lamagetsi), chosinthira ma ultrasound (vibrator), ndi chowumba cha ultrasonic (mutu wa nkhungu, mutu wowotcherera, nyanga).

Jenereta ya ultrasonic (bokosi lamagetsi) Ma transducer a ultrasonic (vibrators), ma ultrasonic molds (mitu ya nkhungu, mitu yowotcherera, nyanga)

1. Jenereta ya ultrasonic (bokosi lamagetsi): Amasintha magetsi a mains kukhala mphamvu yokhazikika ya ma frequency apamwamba komanso yamagetsi apamwamba.

2. Chosinthira ma ultrasound (chozungulira): Chipangizo cholankhulira chomwe chimasintha mphamvu, kusintha mphamvu zamagetsi kukhala mphamvu yamakina.

3. Chokulitsa mawu: Kutalika kwa kugwedezeka kwa makina a transducer kumasinthidwa kudzera mu chiŵerengero cha phindu chomwe chinapangidwa kale.

4. Zinyalala (mitu yowotcherera, nyanga): Yopangidwa mwapadera malinga ndi zosowa za ntchito zowotcherera ndi kudula, ndipo yapangidwa ndi mawonekedwe a mawu kuti ikwaniritse zofunikira za resonance ya dongosolo la ultrasonic. Pansipa, ndigwiritsa ntchito njira zingapo pofotokoza zomwe zimachitika pokonza ma parameter mu ntchito.

Mphamvu = Kukula * Kupanikizika * Nthawi * Nthawi Yokhazikika K = Mphamvu * Nthawi

Mafomula omwe ali pamwambapa akuwonetsa kuti pakuwotcherera ndi kudula, kutalika kwa mafunde a ultrasound (omwe angaikidwe pa jenereta), kupanikizika (kupanikizika kwa mpweya kapena mphamvu ya silinda yamagetsi, komanso kulimba kwa kapangidwe kake ndi kuuma), ndi nthawi yotulutsa mafunde zimagwirizana bwino ndi mphamvu yowotcherera ndi kudula. Mwanjira ina, ngati chinthucho sichinadulidwe bwino, magawo awa akhoza kusinthidwa bwino. Kodi izi zikutanthauza kuti magawo awa akakwera, ndiye kuti amakhala abwino? Ayi ndithu!

P = K∗A∗f∗δ, pomwe P ikuyimira mphamvu yowotcherera, mu W ;

K ndi chinthu chosasinthika chomwe kukula kwake kumakhudzana ndi kuyendetsa mawu ndi kutayika kwa mphamvu kwa zinthuzo. Izi zikutanthauza kuti nthawi zambiri timanena kuti zipangizo zosiyanasiyana zimafunikira kusintha kwa magawo osiyanasiyana kuti zikwaniritse zofunikira.

A ikuyimira dera la chodulira cha weld, choyezedwa mu masikweya mita (㎡). Ili ndi malo olumikizirana a chodulira cha weld, kotero kutalika ndi ngodya ya m'mphepete mwa chodulira nthawi zambiri zimatsimikiza derali.

f ndi ma ultrasound frequency, zomwe zikutanthauza kuti mwa chiphunzitso, ma frequency apamwamba ndi osavuta kuwalumikiza. Komabe, pamalingaliro, ma frequency apamwamba, zimakhala zovuta kwambiri kupeza ma amplitude akulu; unit ndi Hz.

d ikuyimira kukula, komwe kumayesedwa mu mamita (m). Mwachidziwitso, kukula kwakukulu kumabweretsa kuwotcherera ndi kudula bwino. Komabe, nthawi yotopetsa ya zinthu zachitsulo imakhudzana ndi kuchuluka kwa zinthu, katundu wa zinthu, kupsinjika, nthawi, kupanikizika, ndi kuuma, motero zimakhudzidwa ndi magawo ena.

Zinthu zisanu ndi chimodzi zomwe zimakhudza zotsatira za kudula ndi kuwotcherera kwa ultrasound:

Kupanikizika + Nthawi + Kapangidwe ka Makina + Zipangizo Zamalonda + Kukonza Ma Bug

1. Kuthamanga kwa kuwotcherera kwa akupanga

Kuyika mphamvu yoyenera pamwamba pa cholumikizira kumapangitsa kuti cholumikiziracho chisinthe kuchoka pa elastic kupita ku pulasitiki, kumalimbikitsa kufalikira kwa mamolekyulu, ndikuchotsa mpweya wotsala kuchokera ku cholumikizira, motero kumawonjezera magwiridwe antchito otseka pamwamba pa cholumikizira. Kupanikizika nthawi zambiri sikupitirira 0.5 MPa.

2. Nthawi yowotcherera/kudula pogwiritsa ntchito ma ultrasound (nthawi yotulutsa mafunde)

Nthawi yoyenera yosungunula ndi nthawi yokwanira yoziziritsira ndizofunikira. Ndi kutentha kokhazikika, nthawi yochepa imabweretsa kuwotcherera kosakwanira, pomwe nthawi yochulukirapo imayambitsa kusintha kwa kuwotcherera, kusefukira kwa slag, komanso nthawi zina malo otentha (kusintha mtundu) m'malo omwe sanawotchulidwe. Ndikofunikira kuonetsetsa kuti pamwamba pa kuwotcherera pamatenga kutentha kokwanira kuti pafike posungunuka bwino kuti pakhale kufalikira kokwanira kwa mamolekyulu ndi kusakanikirana. Nthawi yomweyo, nthawi yokwanira yoziziritsira ndiyofunikira kuti wotchiyo ikhale ndi mphamvu zokwanira.

3. Makulidwe a akupanga

4. Kapangidwe ka makina

Kulondola ndi kukhazikika kwa kupanga chimango kumakhudza mwachindunji zotsatira za kuwotcherera, makamaka pazinthu zina zolondola, komwe kapangidwe ka makina kayenera kufanana ndi kulondola kwa chinthucho.

5. Zipangizo Zamalonda

Zinthu monga zinthu zomwe zili m'zigawo zolumikizidwa, kapangidwe kake, makulidwe ake, ndi kukana kupanikizika zimakhudzanso mwachindunji momwe zolumikizira zimagwirira ntchito.

6. Kukonza zolakwika pa zipangizo

Pomaliza, kuti chinthu chikwaniritse zotsatira zabwino kwambiri zodulira ndi kuwotcherera pogwiritsa ntchito ultrasound, kukonza zolakwika pa zida ndi chitsimikizo chofunikira. Kufananiza ndi kusintha kwa magawo osiyanasiyana komanso kukonza zolakwika pamalopo ndi mainjiniya kumachita gawo lofunikira.
