Kucheka nekushandisa musimboti wekucheka we Ultrasonic uye welding

Nheyo yeKucheka neKushongedza neUltrasonic

Kucheka nekuwedera kweUltrasonic chikamu chidiki chekushandiswa kweUltrasonic muindasitiri, uye yave ichishandiswa zvakanyanya nekuda kwehunhu hwayo husingakuvadzi nharaunda, hunoshanda zvakanaka, uye hunofadza runako.

Musimboti wekucheka nekubatanidza we ultrasonic

Kucheka nekushongedza webbing uchishandisa Ultrasonic kunoshandisa high-frequency mechanical vibration ye20-40kHz, ichiendesa simba kunzvimbo yekubatana kwewebbing kuburikidza nemusoro we welding. 1. Kuchinja Simba: Jenareta ye ultrasonic inoshandura simba remagetsi kuita high-frequency mechanical vibration, iyo inowedzerwa ne amplitude transformer yozoendeswa kumusoro we welding. 2. Kugadzira Kupisa Kwekunetsana: Musoro we welding unodzvanya webbing, zvichikonzera kukweshana kwe high-frequency pakati pemafiber ari mukati me webbing, zvichigadzira tembiricha yepamusoro ye500-1000℃ pakarepo. 3. Synchronous Welding and Cutting: Tembiricha yepamusoro inonyungudutsa webbing fibers (senge nylon ne polyester), nepo welding head pressure ichibatanidza chikamu chakanyunguduka, ichigadzira weld layer yakasimba. Kana ikashandiswa ne cutting edge welding head chaiyo, tembiricha yepamusoro inogona kucheka webbing panguva imwe chete, zvichiita "kucheka + welding" kwakabatana. 4. Kutonhodza uye Kuumba: Mushure mekunge vibration yamira, kudzvanywa kunochengetwa kwemasekondi 0.1-0.5, zvichibvumira nzvimbo yakasungirirwa kuti itonhore uye iome nekukurumidza, zvichipedzisa maitiro ekucheka nekushongedza. (Magadzirirwo epneumatic anopa cushion, zvakare achivimbisa kutonhodza uye kuumbwa panguva yekucheka nekunamira.)

Kuumbwa kwe ultrasonic cutting and welding system

Sisitimu yekubatanidza mapurasitiki inoshandiswa zvakanyanya ine zvikamu zvitatu zvikuru: jenareta yemagetsi (bhokisi remagetsi), transducer ye ultrasonic (vibrator), uye ultrasonic mold (musoro we mold, musoro we welding, horn).

Jenareta yeUltrasonic (bhokisi remagetsi) Matransducer eUltrasonic (vibrators), mamold eultrasonic (misoro yemould, misoro yewelding, nyanga)

1. Jenareta yeUltrasonic (bhokisi remagetsi): Inoshandura simba remagetsi kuita simba rakasimba remagetsi ane simba remagetsi.

2. Ultrasonic transducer (oscillator): Chishandiso chinoshandura simba, chinoshandura simba remagetsi kuita simba remakanika.

3. Chinosimudzira Manzwi: Hukuru hwekudedera kwemuchina we transducer hunochinjwa kuburikidza nekuwedzera kwehuwandu hwakagadzirwa kare.

4. Makumbo (misoro yekunamira, nyanga): Yakagadzirwa zvichienderana nehukuru hwakatarwa zvichienderana nezvinodiwa zvewelding nekucheka, uye yakagadzirwa neacoustic hunhu kuti ienderane nezvinodiwa zve resonance ye ultrasonic system. Pazasi, ndichashandisa mafomula akati wandei kutsanangura chiitiko chekugadzirisa ma parameter mumashandisirwo.

Simba = Amplitude * Kumanikidzwa * Nguva * Nguva dzose K = Simba * Nguva

Mafomula ari pamusoro apa anoratidza kuti mukukwesha nekucheka, amplitude yemafungu e ultrasonic (anogona kuiswa pajenareta), kumanikidzwa (mhepo inomanikidza kana torque yemagetsi ye cylinder, pamwe nekuomarara kwechimiro), uye nguva yekubuda kwemafungu zvine hukama hwakanaka nemhedzisiro yekukwesha nekucheka. Nemamwe mashoko, kana chigadzirwa chisina kuchekwa zvakanaka, ma parameter aya anogona kugadziriswa zvakanaka. Izvi zvinoreva here kuti kana zviyero izvi zvakakwirira, zviri nani? Kwete!

P = K∗A∗f∗δ, apo P inomiririra simba rekuwedera, muW ;

K chinhu chisingachinji chine hukuru hwacho hunoenderana nekufambiswa kweruzha uye kupararira kwesimba rechinhu chacho. Izvi zvinoreva kuti tinowanzo taura kuti zvinhu zvakasiyana zvinoda kugadziriswa kwema parameter akasiyana kuti zvienderane nezvinodiwa.

A inomiririra nzvimbo yekucheka kweweld, inoyerwa mumamita masikweya (㎡). Iyi ndiyo nzvimbo inobatana nekucheka kweweld, saka kureba nekona yemucheto wekucheka zvinowanzo sarudza nzvimbo iyi.

f ndiyo frequency ye ultrasonic, zvichireva kuti, maererano nedzidziso, ma frequency akakwira ari nyore kuabatanidza. Zvisinei, maererano neacoustic, ma frequency akakwira, ndipo pazvinoomera kuwana amplitude yakakura; unit yacho iHz.

d inomiririra amplitude, inoyerwa mumamita (m). Panyaya iyi, amplitude yakakura inoguma nekunamirwa uye kucheka zviri nani. Zvisinei, hupenyu hwekuneta kwezvinhu zvesimbi hunoenderana nehuwandu, hunhu hwezvinhu, kushushikana, nguva, kumanikidzwa, uye kuomarara, uye nekudaro zvinokanganiswa nezvimwe zvinhu.

Zvinhu zvitanhatu zvinokanganisa mhedzisiro yekucheka nekubatanidza ne ultrasonic:

Kumanikidzwa + Nguva + Magadzirirwo eMichina + Zvishandiso zveChigadzirwa + Kugadzirisa Matambudziko

1. Kumanikidzwa kwekushongedza kweUltrasonic

Kuisa kumanikidzwa kwakakodzera pamusoro pewelding kunoita kuti welding material ichinje kubva pa elastic kuenda kupurasitiki, kunokurudzira molecular interdiffusion, uye kubvisa mhepo yakasara kubva paweld, nokudaro zvichiwedzera kushanda kwesealability yeweld surface. Kumanikidzwa kazhinji hakupfuuri 0.5 MPa.

2. Nguva yekuwedera/kucheka kweUltrasonic (nguva yekubuda kwemafungu)

Nguva yakakodzera yekunyunguduka uye nguva yakakwana yekutonhodza zvakakosha. Kana kupisa kuchinge kwagara kwenguva refu, nguva isina kukwana ichaita kuti pave nekuwelda kusina kukwana, nepo nguva yakawanda ichikonzera kuchinja kweweldment, kufurika kweslag, uye dzimwe nguva nzvimbo dzinopisa (kuchinja kweruvara) munzvimbo dzisina welded. Zvakakosha kuve nechokwadi chekuti pamusoro peweld inonwa kupisa kwakakwana kuti isvike pakunyunguduka kwakazara kuti ive nechokwadi chekupararira kwakakwana kwemamorekuru uye kusanganiswa. Panguva imwe chete, nguva yakakwana yekutonhodza inodiwa kuti weld iwane simba rakakwana.

3. Kukura kweUltrasonic

4. Chimiro chemuchina

Kunyatsojeka uye kugadzikana kwekugadzirwa kwemafuremu kunokanganisa zvakananga mhedzisiro yekuwelding, kunyanya kune zvimwe zvigadzirwa zvakanyatsojeka, apo chimiro chemuchina chinofanira kuenderana nekunyatsojeka kwechigadzirwa.

5. Zvigadzirwa

Zvinhu zvakaita sezvinhu zvezvikamu zvakasungirirwa, chimiro chazvo, ukobvu, uye kuramba kumanikidzwa zvinokanganisawo zvakananga mhedzisiro yekusungirirwa.

6. Kugadzirisa midziyo

Mukupedzisa, kuti chigadzirwa chiwane mhedzisiro yakanakisa yekucheka nekushongedza kwe ultrasonic, kugadzirisa michina zvakare ivimbiso yakakosha. Kuenzanisa uye kugadzirisa ma parameter akasiyana-siyana uye kugadzirisa panzvimbo yacho nemainjiniya kunoita basa rakakosha.
