Nekuzivikanwa kwehunyanzvi hwekugadzira welding,ultrasonic waveyave yakagadzirwa senzira itsva yewelding, iyo ine mabhenefiti asingaenzaniswi mukuputira simbi imwechete kana yakasiyana.Nekuti ultrasonic non-metallic welding haidi flux uye ekunze kupisa masosi, iyo welded chimiro hachizokanganiswa nekupisa uye hapazove nekusara kunetseka.
Nhanganyaya kune Ultrasonic welding tekinoroji
Ultrasonic weldingiko kushandiswa kwehigh frequency vibration wave inofambiswa pamusoro pezvinhu zviviri kuti zvipinzwe, kana iri pressure, kuitira kuti zvinhu zviviri izvi zvikweshera pamusoro uye kuumbwa kwekubatana pakati pema molecular layer.Izvo zvikamu zvikuru zveseti yeultrasonic welding systemsanganisiraultrasonic jenareta, ultrasonic transducer, ultrasonic flange, ultrasonic horn, mold uye ultrasonic muchina muviri.
Ultrasonic welding musimboti
Nheyo ye ultrasonic plastiki welding: ultrasonic chiito pane epurasitiki inosangana pamusoro pe thermoplastic, ichagadzira makumi ezviuru zvenguva dzepamusoro-frequency vibration pasekondi, izvi zvinosvika kune imwe amplitude ye-high-frequency vibration, simba re ultrasonic rinoendeswa kune welding. nharaunda, nekuti iyo welding nzvimbo ine maviri welding interface pane inonzwika kuramba, saka inoburitsa tembiricha yemuno.
Uye nekuda kwehurombo hwekupisa kwepurasitiki, haigone kugovaniswa nenguva, yakaunganidzwa munzvimbo yewelding, zvichikonzera kukurumidza kunyungudika kwekusangana kwemapurasitiki maviri, uye kumwe kudzvanywa, zvekuti inosanganiswa mune imwe. .Kana iyo ultrasonic inomira kushanda, rega kumanikidzwa kuenderere mberi kwemasekondi mashoma kuti asimbise, kugadzira cheni yakasimba yemamorekuru anogona kubatanidza nesimba riri pedyo neiyo yezvakagadzirwa.
Hunhu hweiyo ultrasound yepurasitiki welding zvinoenderana neamplitude ye transducer welding musoro, iyo yakawedzera kudzvanywa uye welding nguva uye zvimwe zvinhu zvitatu, welding nguva uye welding musoro kudzvanywa kunogona kugadziriswa, iyo amplitude inotarwa neiyo transducer uye amplitude tsvimbo.
Pane kukosha kwakakodzera kwekudyidzana kwezvizhinji zvitatu izvi.Kana simba richipfuura kukosha kwakakodzera, kunyunguduka kwepurasitiki kuchave kwakakura uye iyo welding zvinhu zviri nyore kukanganisa.Kana simba racho riri diki, hazvisi nyore kuti weld, iyo yakawedzera kumanikidza haigone kuve yakakura.Iyi optimum pressure ndiyo chigadzirwa chehurefu hwehurefu hwechikamu chakashongedzwa uye yakanyanya kudzvanywa pa 1mm yemupendero.
Nheyo ye ultrasonic metal welding: Nheyo ye ultrasonic metal welding inzira yakakosha yekubatanidza simbi dzakafanana kana dzakasiyana nekushandisa iyo mechanical vibration simba re ultrasonic frequency (kupfuura 16KHz).Metal in ultrasonic welding, kana kuendesa ikozvino kune workpiece, kana workpiece inoiswa kune yakakwira tembiricha yekupisa sosi, asi pasi pesimba rekumanikidza, iyo vibration simba reiyo furemu mukati mekukisana kwebasa pakati pechishandiso, deformation simba uye kushoma tembiricha kukwira. .
Metallurgical bonding pakati pemajoini is solid state welding pasina kunyunguduka kwe base metal.Naizvozvo, inogona kukunda zvinobudirira iyo spatter uye oxidation inokonzerwa nekupokana welding.Ultrasonic welding machine inogona kushandiswa kune imwe chete point welding, multi point welding uye short strip welding yemhangura, sirivheri, aluminium, nickel uye mamwe asina-ferrous simbi filaments kana matete mapepa zvinhu.Inogona kushandiswa zvakanyanya mukushongedza kwesilicon inodzorwa lead, fuse chidimbu, magetsi lead, lithium bhatiri pole chidimbu uye pole nzeve.
Ultrasonic welding process
1) Welding nzira: ine ultrasound yakakwira frequency vibration welding musoro pasi pekumanikidzwa kuri pakati nepakati, gadzira zvidimbu zviviri zvepurasitiki yakabatana pamusoro pemhepo kupisa uye nekukasira kunyunguduka, simba rewelding rinogona kufananidzwa neontology, tora zvigadzirwa zvakakodzera uye inonzwisisika interface dhizaini, inogona kuzadzisa. isina mvura uye isingapindi mhepo, uye SHANDISA AIDS kusagadzikana kwekukanzura, kushanda zvakanaka kwakachena welding.
2) Chimiro: yakafanana nemaohan nzira, iyi nzira ichave concave shape welding musoro kumanikidzwa mupurasitiki yekunze mhete, sonic welding bvudzi rakasara mushure mekupedzisira-yakakwirira frequency vibration ichanyunguduka kuumba uye mapurasitiki akaputirwa musimbi zvinhu kuti zvigadzirwe, uye yakatsetseka. uye chitarisiko chakanaka, iyi nzira inoshandiswa mumagetsi, nyanga yechimiro chakagadziriswa, uye zvizoro zve lens zvakagadziriswa, nezvimwe.
3) Kupisa kwekupisa: nekufambiswa kwemusoro wewelding uye kudzvanywa kwakakodzera, zvikamu zvesimbi (senge nzungu, screws, nezvimwewo) zvinodzvanywa mugomba repurasitiki rakachengeterwa uye rakamiswa pane imwe kudzika.Mushure mekupedzwa, kushushikana uye torque inogona kufananidzwa nesimba rechinyakare mold kuumba, iyo inogona kudzivirira hurema hwekukuvadza jekiseni mold uye inononoka jekiseni.
4) Riveting welding: riveting welding nzira inoreva kuzununguka kwemusoro wewelding kudzvanya protrusion yechinhu kuitira kuti kupisa kunonyungudika kuita rivet chimiro, kuitira kuti zvinhu zviviri izvi mechanical riveting.
5) Spot welding: Spot welding inoreva poindi welding yechinhu chisiri nyore kugadzira iyo welding mutsara, iyo inogona zvakare kuwana iyo welding mhedzisiro.
Inokodzera zvinhu zve ultrasonic welding
1. Ultrasonic welding yakakodzera kune ese thermoplastics, amorphous mapurasitiki akadai ABS,PMMA,PC,PS;Semi-crystalline mapurasitiki akadai PA, PET, CA, POM, Pe uye PP.
2. Ultrasonic welding yakakodzerawo kune micheka isina-textile, yakadai semucheka we thermoplastic, zvinhu zvepolymeric, mapepa akavharidzirwa uye micheka yakasanganiswa.
Chikamu chinotevera isu tinokuratidza iwe ultrasonic welding muchina wakashandiswa zvakanyanya zvinhu uye ultrasonic welding welding interface dhizaini uye minda yekushandisa, kana uchiifarira, ndapota titevere.
Isu tiri nyanzvi mukugadzirwa kwe ultrasonic welding machine, high frequency welding machine, ultrasonic generator, metal welding machine, custom welding machine, etc. Kana iwe uchida kuziva chero chinhu nezve ultrasound teknolojia, tapota inzwa wakasununguka kutibata nesu.
