2. 1 35 kHz Iimfuno zophando zezixhobo zeplastiki zeplastiki zokuwelda izixhobo zophando
Kwi-35 kHz iplastiki ye-ultrasonic welding mechanical structure, ukwenzela ukuba kuqinisekiswe ukuba isakhiwo sayo sophuhliso olufanelekileyo, ezi mfuno zilandelayo ze-5 kufuneka zifezekiswe.
(1) kufuneka siqinisekise ukuba amandla kwi-ultrasonic anokukhokelwa kwindawo ye-welding, ngokuqhelekileyo inokudityaniswa isakhiwo somgca owenziwe kwikona ebukhali, kwaye incam yekona ibekwe kwi-chamfering, i-radius ye-chamfering kufuneka ilawulwe ngaphakathi. I-0.1mm, Ukuze wenze isikhokelo samandla, i-Angle ebukhali ingakhetha i-45, i-60, i-90 kunye ne-120 degrees, kwaye ukuphakama kwesikhokelo samandla kufuneka kuhlengahlengiswe ngokuhambelana nenxalenye ye-welding yodonga kunye nezinto eziphathekayo, ngokuthetha ngokubanzi, isikhokelo samandla. ukuphakama akufanele kube ngaphantsi kwe-1/2 yobunzima bodonga lwezinto eziphathekayo, kwaye ukuze ugweme ingxaki yesikhokelo samandla angaphezu kwamandla.Iya kuqinisekisa ukuba iradiyasi ye-chamfering kwezinye izakhiwo zoomatshini iya kuba ngaphezulu kwe-0.2mm;
(2) Kwi-welding ye-mechanical ye-welding kufuneka iqinisekise ukuba uphondo lwe-welding lunokuqhagamshelana ngokupheleleyo, intloko ye-welding kufuneka isondele ngokusemandleni kwi-welding position, ukwenzela ukuba intloko ye-welding igutyungelwe ngokupheleleyo yi-welding position;
(3) Ulwakhiwo lwe-Welding kufuneka lube nenkxaso yesakhiwo somatshini, ukwenzela ukuba siphephe ukulahlekelwa kwamandla ekutshintsheni, sinokusebenzisa izixhobo zokuxhasa ukhuseleko lwesakhiwo somatshini, indawo yokuxhasa kufuneka ibe kabini ubuncinane njengoko i-welding line joint, kwaye yenza indawo yokuxhasa ngokusondeleyo kwindawo yokuxhasa;
(4) kwi-welding kufuneka iphephe ukugqithiswa kwe-welding, ngenxa yeplastiki ye-amorphous, ayinakutywinwa, ubukhulu bodonga lwendawo ye-welding kufuneka ilawulwe kwi-1 mm, xa indawo yokutywina ingagqitywanga, vula nje itywina layo elingaphakathi, kwaye enye yemigangatho inokutywinwa, ukwenzela ukukhusela ngokufanelekileyo ukubonakala komgangatho wezinto eziphathekayo, Kwaye kwi-adhesion ye-welding nayo iqinisekisiwe ngakumbi;
(5) Ukufuduswa kwe-weld kunye nomthamo uya kugcinwa ukuvumela ukuhamba okukhululekile kokunyibilika ngaphakathi kwendawo ye-weld ukuphepha ukuvala i-gap ye-weldment yeplastiki.
2. 2 Isakhiwo somgca we-ultrasonic eqhelekileyo
Isakhiwo esiqhelekileyo somgca we-ultrasonic ikakhulu lulwimi oludibeneyo, i-V groove, i-step joint kunye ne-shear joint.Kwinxalenye yeplastiki ye-welding yomatshini kunye nobukhulu bodonga obungaphezulu kwe-1.5mm, ulwimi kunye nesakhiwo somgca we-welding yeyona nto ifanelekileyo, kwaye kwiimveliso ze-welding zoomatshini ezinobunzima bodonga malunga ne-1mm, isiteji somgca we-welding sinokusetyenziswa. .Xa ubukhulu bodonga bungaphantsi kwe-1 mm, icandelo elithambekeleyo lohlobo lwe-welding line structure lingasetyenziswa, kwaye ukuba imveliso ye-welding incinci, ukuchaneka kunye nomgangatho we-welding uphezulu, i-V-groove uhlobo lwe-welding line structure ingasetyenziswa.
3. isiphelo
Ukushwankathela, xa usebenzisa i-35 kHz iteknoloji ye-welding yeplastiki ye-ultrasonic ukukhangela isakhiwo somatshini, kuyimfuneko ukuqwalasela ipropati yokutywinwa kwesakhiwo somgca we-welding.Ulwakhiwo lomgca wenyathelo lokuwelda unokuqinisekisa ukutyeba kodonga olucekethekileyo lwamacandelo.Kwangaxeshanye, ukuphuhliswa kwesi sakhiwo kunokunciphisa ubunzima benkqubo yokubumba inaliti yokungunda.Emva koko usombulule ingxaki yokugqithisa ngokufanelekileyo, ukwenzela ukuba ukungazinzi kwenkqubo kwinkqubo ye-welding kuncitshiswe kakhulu, ukwenzela ukuba ukuveliswa kwemveliso kuphuculwe kakhulu.
