1. Kusanzwisisa welding workpiece
Ultrasonic simba rinoputika pakarepo, iyo welding line inofanira kuumbwa kuita mapoinzi kana mitsetse uye kureba kwekufambisa kunofanirwa kuenderana neiyo ultrasonic welding nzira. Vamwe vanhu vanofunga kuti chero bedzi chiri chinhu chepurasitiki, zvisinei kuti nzvimbo yakabatana inogona kusungirirwa zvakanaka sei, uku ndiko kunzwisisa kusina kunaka. Kana simba repakarepo rinogadzirwa, iyo yakakura nzvimbo yejoint, iyo yakanyanya kusimba yekuparadzira simba, iyo yakaipisisa iyo welding mhedzisiro, uye kunyange welding hazvigoneke. Ultrasonic mafungu anotapurirwa kureba, kurasikirwa kwesimba kunoenderana nedaro, uye kureba kunofanirwa kudzorwa mukati me7.5 cm. Mutsara wekugadzira unofanirwa kudzorwa pakati pe 0.3-0.8mm seyakanakisa mamiriro, uye madziro emadziro e workpiece haafaniri kunge ari pasi pe2mm, kana zvisina kudaro haigoni kusungirirwa zvakanaka, kunyanya kune zvigadzirwa zvinoda kuvhara mvura.
2. Kusanzwisisa workpiece zvinhu
Ultrasonic welding michina ine zvinodiwa pamidziyo yewelded workpieces. Hazvisi zvese zvekushandisa zvinogona kusungirirwa. Vamwe vanhu vanofunga kuti chero chinhu chinogona kuiswa welding. Uku kusanzwisisa kukuru. Zvimwe zvinhu zvakasiyana zvinogona kusungirirwa zvakanaka, uye zvimwe zvinogona kuvezwa. Zvimwe hazvienderani. Iyo yekunyungudika yechinhu chimwe chete chakafanana, uye inogona kuve yakashongedzwa mumusimboti. Asi kana iyo yakanyunguduka yeweld workpiece yakakura kupfuura 350 madhigirii, haichakodzeri kune ultrasonic welding. Nekuti ultrasound inonyungudutsa mamorekuru eiyo workpiece ipapo, hwaro hwekutonga huri mukati me1-3. Kana iyo welding isiri yakanaka, iwe unofanirwa kusarudza mamwe maitirwo emagetsi, senge hot plate, spin melting, vibration uye friction. Kazhinji kutaura, zvinhu zveABS ndizvo zviri nyore kuita weld nekuda kwekudzika kwayo kunyungudika nekuoma kwayo. Kusiyana neizvi, naironi ndiyo yakanyanya kuoma kuisa weld.
3, Zvikanganiso mukusarudzwa kwe ultrasonic
Ingani simba rekubuda rekushandisa, oscillation frequency, uye amplitude range inofanirwa kutariswa zvinoenderana nechinhu cheiyo workpiece, nzvimbo yewaya welding, kana paine zvinhu zvemagetsi mune workpiece, uye kana isina mhepo. Ngano ndeyokuti kukura kwesimba, zviri nani. Ukuwo kusanzwisisa. Kana iwe usingazivi zvakawanda nezve ultrasound. Zvakanakisa kubvunza mainjiniya uye tekinoroji vashandi veyakajairwa ultrasonic kugadzira chirimwa. Kana zvichibvira, zvakanakisisa kutaurirana nemugadziri panzvimbo, uye usateerera neupofu kutsausa kwevamwe vasina kurongeka vekutengesa ultrasound vashandi. Parizvino, makambani anogadzira michina yakabatana anonyanya kuomarara, mazhinji acho ari mashopu emhuri, ayo anoteedzera dunhu rakasimba, uye anoita seanonzwisisa nheyo yekushanda. Mudziyo wakakopwa une chikanganiso chinouraya. Imwe ndeyekuti mhando yezvigadzirwa zvakatengwa hazvigone kuvimbiswa, uye iyo yakakosha tekinoroji yechipiri yekugadzira maitiro haina hunyanzvi. Iyo midziyo inowanzoita isina kugadzikana panguva yepakati uye yakakwirira simba rekushanda, uye chiyero chekufanirwa kwechigadzirwa chakaderera. Dzimwe nguva michina yacho inokuvadzwa. Zvakadai senge simba rekushandura re transducer, maparamita emagetsi anoshandiswa haagoni kuyerwa, magnetic saturation magnetic flux density (Bs), magnetic induction intensity (Bm), inoshanda magineti permeability (Ue), residual magnetic flux density (Br), coercivity (A / M) nezvimwewo. Nzira yekuputira mhepo yakaoma zvikuru, uye izvi hazvigoni kuitwa mabasa epamba. Nokudaro, kutenga ultrasound, zvakanakisisa kunzwisisa mamiriro ekambani kutanga. Nenzira iyi chete inogona kuderedza dambudziko risingakoshi mune ramangwana.
4, kusanzwisisa kwe ultrasonic kubuda simba
Simba rinobuda reiyo ultrasonic wave rakafanana nedhayamita uye ukobvu hwepiezoelectric ceramic sheet, zvinhu, uye maitiro ekugadzira. Iyo transducer yakaumbwa uye iyo yakanyanya simba inoumbwa. Kuyera simba rinobuda inzira yakaoma. Hazvirevi kuti iyo yakakura iyo transducer, iyo yakawanda simba machubhu anoshandiswa mudunhu, iyo yakakura inobuda simba. Inofanirwa kuda chimbo chekuyeresa chakanyanya kuoma kunzwisisa kuyera amplitude nemazvo. Yakabatana nekutsausa kwevashandi vekutengesa, inopa vatengi kunzwisisa kusina kunaka kuti huwandu hwemagetsi emagetsi anopedzwa hahuratidzi hukuru hwekubuda kwe ultrasonic simba. Kana iyo longitudinal simba inogadzirwa yakaderera uye ikozvino kushandiswa kwakakura, inogona kungotsanangura kushanda kwemidziyo, pasina simba. Say.
5. Kusanzwisisa mune welding musimboti
Huwandu hwakati wandei hwevanhu vanga vachiita ultrasonic welding kwemakore mazhinji vane kusanzwisisana nezve kutapurirana kwe ultrasonic simba. Zvinotendwa kuti kusungirirwa kwemasaisai eruzha pane yekubata kumeso ndiko kusanzwisisa. Iyo yechokwadi welding musimboti ndeyekuti mushure meiyo transducer inoshandura simba remagetsi kuita mechanical simba, rinopfuura nepakati workpiece The material molecules conduct, uye ruzha wave inoitisa ruzha kuramba mune solids iduku zvikuru kupfuura ari mumhepo. Kana ruzha ruchipfuura nepakati pekubatana kwechishandiso, iyo acoustic kuramba iri mugomba yakakura, uye iyo inogadzirwa simba rekupisa rakakura. Iyo tembiricha inotanga kusvika pakunyunguduka kweiyo workpiece, uyezve Nekumwe kudzvanywa, musono unoiswa welded, uye zvimwe zvikamu zveworkpiece hazvizove welded nekuda kwekuderera kweacoustic resistance uye kuderera kwekushisa. Nheyo yacho yakafanana nemutemo waOhm.
6, Kusanzwisisana kwekugadzira welding
Mhando dzakasiyana dze ultrasonic molds (Nyanga), chimiro chebasa rekushanda chinotarisa chimiro chechimiro, asi ukuru uye radian yechikamu chimwe nechimwe inofanira kunyatsoverengwa. Vamwe vanhu vanofunga zvisiri izvo kuti inongova simbi. Kunyangwe iyo dhizaini inonzwisisika kana kusakanganisa yakanangana nekushanda, hupenyu hurefu, chiyero chekukodzera chigadzirwa che mold, uye yakananga kupisa jenareta mumatambudziko akaomarara. Izvo zvinhu zve mold zvinowanzoita magnesium aluminium 7075, uye vamwe vanhu vanoshandisa zvinhu zvakaderera kuderedza mutengo. Vagadziri venguva dzose mold vane seti yekuomesera yekuongorora maitiro ezvinhu zvinopinda, uye zviyero zvakagadziriswa zvinogadziriswa mushure mekombuta software simulation uye ongororo. Hunhu hunovimbiswa. Matanho aya haagone kuitwa nemawekishopu. Pasina dhizaini inonzwisisika, molds inogadzirwa haizove nedambudziko rekuita zviri pachena kana welding madiki workpiece. Kusiyana kwakasiyana-siyana kuchaitika kana simba repamusoro rinoshandiswa. Mumatambudziko akaoma, kuvadza zvakananga zvikamu
