Ucwaningo lwe-ultrasonic plastic welding equipment structure-II

2. 1 35 kHz Izidingo zocwaningo lwesakhiwo semishini yokushisela yepulasitiki ye-ultrasonic

Ku-35 kHz ultrasonic plastic welding mechanical structure, ukuze kuqinisekiswe ukuthi isakhiwo saso sithuthuka ngendlela efanele, lezi zidingo ezilandelayo ezi-5 kufanele zihlangatshezwe.

(1) kufanele siqinisekise ukuthi amandla ku-ultrasonic angaqondiswa endaweni yokushisela, ngokuvamile angafakwa umugqa wesakhiwo owenziwe ekhoneni elicijile, futhi ichopho lekhoneni libekwe endaweni eyi-chamfering, i-chamfering radius kufanele ilawulwe ngaphakathi. 0.1mm, Ukuze wakhe umhlahlandlela wamandla, i-Angle ebukhali ingakhetha amadigri angu-45, 60, 90 no-120, futhi ukuphakama komhlahlandlela wamandla kudinga ukulungiswa ngokuvumelana nengxenye yokushisela odongeni kanye nezinto ezibonakalayo, ngokuvamile, umhlahlandlela wamandla. ukuphakama akufanele kube ngaphansi kwe-1/2 yobukhulu bodonga olubonakalayo, futhi ukuze ugweme inkinga yomhlahlandlela wamandla amaningi.Izoqinisekisa ukuthi i-radius ye-chamfering kwezinye izakhiwo zemishini izoba ngaphezu kuka-0.2mm;

(2) Emshinini we-welding welding kufanele uqinisekise ukuthi uphondo lwe-welding lungathintana ngokugcwele, ikhanda le-welding kufanele libe eduze ngangokunokwenzeka endaweni yokuthungatha, ukuze ikhanda le-welding likwazi ukumbozwa ngokugcwele yi-welding isikhundla;

(3) Isakhiwo se-Welding kufanele sibe nesakhiwo somshini wokusekela, ukuze sigweme ukulahlekelwa kwamandla ekudluliseni, singasebenzisa i-tooling ukusekela ukuvikelwa kwesakhiwo semishini, indawo yokusekela kufanele ibe okungenani kabili kune-joint welding line, futhi indawo yokusekela njengoba iseduze nendawo yokusekela;

(4) in the Welding kufanele ugweme Welding ukuchichima, ngoba plastic amorphous, ayikwazi uvalwe, ukushuba odongeni isikhundla Welding kufanele ilawulwe at 1 mm, lapho indawo uphawu ingaphelele, nje uvule ohlangothini uphawu yayo yangaphakathi, futhi enye yezindawo ezingaphezulu ingavalwa, ukuze kuvikelwe ngempumelelo ukubukeka kwekhwalithi yezinto ezibonakalayo, Futhi ekunamatheleni kwe-welding nakho kuqinisekisiwe ngokwengeziwe;

(5) Ukususwa kwe-weld kanye nevolumu kuzogodlwa ukuvumela ukugeleza okukhululekile kokuncibilika ngaphakathi kwendawo yokushisela ukugwema ukuvinjwa kwegebe lokushisela epulasitiki.

2. 2 Isakhiwo somugqa we-ultrasonic esivamile

Isakhiwo somugqa we-ultrasonic esivamile ikakhulukazi inhlanganisela yolimi, i-V groove, i-step joint kanye ne-shear joint.Ezingxenyeni zepulasitiki zokushisela ngomshini ezinobukhulu bodonga obungaphezu kuka-1.5mm, umugqa wokushisela wolimi ne-groove yiwona ofaneleka kakhulu, futhi emikhiqizweni yokushisela ngomshini enogqinsi oluyi-1mm, umugqa wokushisela wesiteji ungasetshenziswa. .Uma ubukhulu bodonga bungaphansi kwe-1 mm, isakhiwo somugqa we-welding wesigaba esithambekele singasetshenziswa, futhi uma umkhiqizo wokushisela umncane, ukunemba kanye nekhwalithi ye-welding iphezulu, isakhiwo se-V-groove sohlobo lwe-welding singasetshenziswa.

3. isiphetho

Ukufingqa, lapho usebenzisa ubuchwepheshe be-welding yepulasitiki ye-35 kHz ukucinga isakhiwo somshini, kuyadingeka ukucabangela impahla yokuvala yesakhiwo somugqa wokushisela.Isinyathelo Welding line isakhiwo kungaqinisekisa mncane odongeni ukushuba izingxenye.Ngesikhathi esifanayo, ukuthuthukiswa kwalesi sakhiwo kunganciphisa futhi inkimbinkimbi yenqubo yokubumba umjovo wesikhunta.Bese uxazulula inkinga yokuchichima ngokuphumelelayo, ukuze ukungazinzi kwenqubo yenqubo ye-welding kuncishiswe kakhulu, ukuze ukusebenza kahle kokukhiqiza kuthuthukiswe kakhulu.
