I. Chii chinonzi ultrasound?

Mafungu eUltrasonic inzira inoshandisa simba rinogadzirwa nekudengenyeka kwefrequency yepamusoro kuti rishande pamusoro pechinhu chebasa, zvichiita kuti zvikamu zvesimbi zvibatane.

II. Nheyo yekushanda kwema Ultrasonic Waves

1. Simba remagetsi rinoshandurwa kuita high-frequency mechanical vibration, iyo inozotumirwa ku welding nozzle kuburikidza ne acoustically tuned welding head. Workpieces dzepamusoro nedzepasi dzinokwizana pasi pekumanikidzwa kwe20,000 kana 40,000 kasekondi. Mugumisiro wakabatana we high-frequency vibration nekumanikidzwa unoparadzira chidimbu chakatetepa chezvinhu nema oxides pamusoro pe workpiece, zvichiita weld yakachena uye inodzorwa. Kuburikidza ne recombination yemaatomu pakati pe workpieces, metallurgical fusion layer yakavimbika inozogadzirwa.
2. Mwenje we low-frequency unoshandurwa kuita mwenje we high-frequency nejenareta. Mwenje we high-frequency unozoshandurwa kuita mechanical vibration ne transducer. Amplitude modulator ne welding head zvine basa rekugadzirisa vibration amplitude. Pasi pekumanikidzwa kwakati, mamorekuru ari pamusoro pesimbi anokweshana uye anobonderana, zvichiita kuti intermolecular interpenetration, nokudaro achipedzisa welding.

Ruzivo rwekutanga uye kugadzirisa matambudziko e ultrasound

III. Zvikanganiso Zvakajairika Mukushongedza Ultrasonic

(a) Kubatanidza kusina kukwana

1. Simba rekubuditsa welding harina kukwana: kumanikidzwa kusina kukwana, amplitude isina kukwana, kana kuti hwaro hahuna kugadzika zvakanaka.
2. Simba rekuwelda risina kukwana: Fomura yekuverenga simba rinobuda ndeye E=P×T=F×V×T=μN×A×f×T (apo E isimba, P isimba, V ispeed, μ i coefficient of friction, N i pressure, A i amplitude, f i frequency, uye T i time). Simba risina kukwana richaita kuti welding isashande zvakanaka.
3. Mafuta kana oxide layers pamusoro pechinhu ichi zvinogona kukanganisa kushanda kwe welding bonding effect.
4. Kana mazino acho akapinza zvakanyanya, anogona kupinda nyore nyore mu weldment panguva yekuwelding.
5. Pamusoro pe weldment pane chifukidziro chezvinhu zvisina kukodzera ku ultrasonic welding.
6. Zvinhu zviri kusungirirwa hazvina kukodzera kusungirirwa ne ultrasonic.

(ii) Hwaro hwemusoro wekunamira

Chikonzero : Kana musoro we welding kana base yekuwelding yasangana nechinhu chacho, tembiricha yakakwira zvikuru inogadzirwa, zvichikonzera kupinda kwemamorekuru pakati pechinhu chacho nemusoro we welding kana base, zvichikonzera kunamira.

Mhinduro :

1. Ongorora mazino emusoro nepasi pechishandiso chekunamira. Kana kusakara kwakanyanya, kuchaita kuti tembiricha ikwire, uye inofanira kugadziriswa nenguva.
2. Kunyangwe paine mhedzisiro yekuwelda, simba rinogona kuwedzerwa zvakakodzera uye nguva yekuwelda ipfupiswe kuderedza kuchinjana kwesimba kwakanyanya pakati pemusoro wekuwelda nezvinhu.

(iii) Kupwanya kwesimbi

1. Kutsemuka kwakatenderedza jira rekukwevera: Pakukwevera zvinhu zvakawanda, mupendero wejira rekukwevera unoumba mupendero. Kana musoro wekukwevera uchidedera, unoshandisa simba rekukwevera kumucheto, izvo zvinogona kukonzera kutsemuka nyore nyore.
2. Mhinduro : Ita basa rakakosha pamucheto wejoinhi re weld kuti uve nechokwadi chekupararira kwakaenzana kwekushushikana uye kuderedza simba rekudhonza rinokonzereswa nekudedera.
3. Matsemuka ari pedyo nejoini resolder: Kudedera kwemusoro wesoldering kunoita kuti chinhu chifambe-fambe. Semuenzaniso, kana foil yealuminium yakabatana nebhatiri, kudhonza kunogona kukonzera kutyoka nyore nyore.
4. Mhinduro : ① Chinja divi remaitirwo ezino (semuenzaniso, shandisa mapatani edhinari) kuti ugadzirise divi resimba pachinhu chacho; ② Wedzera jira rematabhu zvakakodzera kuti ugadzire nzvimbo yekubata pakati pebhatiri nejoini resolder.

(iv) Kuchinja kukuru kwesimba rinobuda

Chikonzero : Pane zvinhu zvakawanda zvinokanganisa simba rekuburitsa, uye zvinoda kuongororwa chimwe nechimwe.

Mhinduro :

1. Ongorora kuiswa kwechikamu chetatu, tarisa kana paine kukuvara, uye chiunganidze zvakare kana zvichidikanwa.
2. Tarisa kuti zvikukuru zvepasi zvakasungwa zvakanaka.
3. Tarisa kana paine mipata panzvimbo yechigadziko chekusimbisa.
4. Ongorora zvinhu zvekunamira kuti uone kana nzvimbo dzekunamira dzakafanana nguva imwe neimwe.
5. Tarisa pamusoro pechinhu chacho kuti uone kana paine mavara e okisijeni kana mafuta.
6. Simbisa kuti zvirevo zvezvinhu zvinouya zvinoenderana (kana tambo yemusoro we welding yakagadziriswa, musiyano muukobvu nekuoma kwezvinhu zvinokonzeresa kushanduka kwesimba rekubuda).
7. Tarisa kugadzikana kwemhepo inopinzwa mufekitori uye tarisa kana paine kuchinja-chinja kwechiyero chemhepo inopinda.
8. Tarisa kana kubuda kwe ultrasonic kwebhokisi remagetsi kwakasimba.

(v) Kuremerwa zvakanyanya

Zvinokonzera zvinosanganisira mamiriro maviri: kuwandisa simba uye kuwandisa kakawanda.

Mhinduro :

1. Deredza maparamita ekuwelding zvakakodzera.
2. Deredza kudzika kwemusoro we welding kuti uve nechokwadi chekuti pane mukaha wakakura pakati pemusoro we welding nehwaro.
