Ukulungiswa kokwenza i-stretch forming yindlela yokucubungula i-stamping esebenzisa i-mold ukwenza i-flank ethe tyaba ibe yindawo evulekileyo engenanto. Njengenye yeenkqubo eziphambili zokustamping, i-stretch isetyenziswa kakhulu. Inkqubo yokwandisa ingasetyenziselwa ukwenza iindawo zodonga ezisi-cylinder, rectangular, stepped, spherical, conical, parabolic kunye nezinye iindawo zodonga ezimile ngendlela engacwangciswanga. Ukuba idityaniswe nezinye iinkqubo zokwenza i-stamping, inokuvelisa iindawo ezineemilo ezintsonkothileyo.

Sebenzisa izixhobo zokustampa xa usenza ulungiso lweemveliso, kuquka: ukucubungula uhlengahlengiso, ukuhlaziya uhlengahlengiso, ukuhlaziya uhlengahlengiso kunye nokunciphisa uhlengahlengiso, njl. Ukucubungula uhlengahlengiso: Sebenzisa isixhobo sepleyiti yokucinezela ukuze usebenzise amandla okubetha uhlengahlengiso ukutsala inxalenye okanye yonke into ethe tyaba kwingxobo yesikhunta esigobileyo ukuze uyenze ibe yisikhongozeli esinomzantsi. Ukucubungula udonga olusecaleni lwesikhongozeli oluhambelana necala lokwahlula luhlengahlengiso olucocekileyo, ngelixa ukucubungula uhlengahlengiso lwezikhongozeli ezimile okwekhoni (okanye iphiramidi), izikhongozeli zehemispherical, kunye nezikhongozeli zomphezulu weparabolic kukwabandakanya ukwandiswa kokucubungula.

Ukulungiswa kwakhona kolulwe: oko kukuthi, kwiimveliso ezitsalwe nzulu ezingenakugqityezelwa kwinkqubo enye yolulwe, kuyimfuneko ukolula imveliso eyenziweyo emva kokulungiswa kolulwelwe ukuze kwandiswe ubunzulu besikhongozeli esenziweyo.

Ukulungiswa kokwelula okungasemva: Ukwelula okungasemva kwesixhobo somsebenzi esoluliweyo kwinkqubo yangaphambili, icala langaphakathi lesixhobo somsebenzi liba licala langaphandle, kwaye ukwenziwa kobubanzi bangaphandle buncinci bunciphile. Kwindawo engaphakathi yesikhunta esigobileyo enobubanzi bangaphandle obuncinci kancinci, ububanzi bangaphandle besikhongozeli esinomzantsi buyancitshiswa, kwaye ubukhulu bodonga buyancitshiswa ngaxeshanye, oku kungasusi nje kuphela ukuphambuka kobukhulu bodonga, kodwa kwenza nomphezulu wesikhongozeli ube mpuluswa.

Oku kulandelayo kwazisa iintlobo ezimbini zokunyathela kunye nokuzolula ngesinyithi xa kusetyenziswa izixhobo zokunyathela:

1. Ukucutshungulwa komzobo we-cylindrical + (Umzobo ojikelezayo): ukolulwa kweemveliso ze-cylindrical. Zombini i-flange kunye nezantsi zikwimo yeplane, udonga olusecaleni lwesilinda lu-axisymmetric, kwaye ukuguquka kusasazwa ngokulinganayo kumjikelezo ofanayo, kwaye iinwele ezikwi-flange zonakele ukuze zibangele ukuguquka okunzulu komzobo.

2. Ukucutshungulwa komzobo we-ellipse+ (Umzobo we-ellipse): Ukuguquka kweenwele kwi-flange kukuguquguquka okuxineneyo, kodwa ubungakanani bokuguquka kunye nomlinganiselo wokuguquka kutshintsha ngokufanayo kwimilo ye-contour. Okukhona ukugoba kukhulu, kokukhona ukwanda kokuguquka kweplastiki yoboya, kwaye ngokuchaseneyo, okukhona ukugoba kuncinci, kokukhona ukugoba kuncinci kokuguquka kweplastiki yoboya.
