Kusiyana zida zotseketsa pafupipafupi ndi kuzimitsa laser

1. Kuzama kwa zida zozimitsira pafupipafupi kumasiyana malinga ndi mawonekedwe, mawonekedwe a gawo, kukula ndi magawo aukadaulo a laser, ndipo kukula kwake kuli pakati pa 0.3 ~ 2.0mm. Ikhoza kuzimitsa zolemba zamagulu akuluakulu a shaft ndi malo a mano a magiya akuluakulu popanda kusintha kuuma kwa pamwamba, ndipo ikhoza kukwaniritsa zofunikira za ntchito zogwirira ntchito popanda makina otsatila.

2. Laser kuzimitsa ndi kuumitsa pamwamba zinthu. Laser imagwiritsidwa ntchito kutenthetsa pamwamba pa zinthu pamwamba pa malo osinthika. Zinthu zikazizira, austenite imasinthidwa kukhala martensite.

Kuzimitsa kwa laser kumakhala ndi kuuma kwakukulu kozimitsa (nthawi zambiri 1-3HRC yokwera kuposa kuzimitsa kulowetsedwa), wosanjikiza wowuma yunifolomu, mapindikidwe ang’onoang’ono a workpiece, ntchito yosavuta yopangira kutentha kwakuya ndi njira yowotchera, osafunikira kugwiritsa ntchito koyilo yolowera, ndipo palibe chifukwa chomvera. mankhwala kutentha kwa processing zigawo zikuluzikulu Zoletsa kukula kwa ng’anjo pa kutaya. Komanso, tikhoza kunyalanyaza mapindikidwe a workpiece pambuyo kuzimitsa laser. Laser quenching makamaka oyenera mankhwala pamwamba pa zigawo zomwe zimafuna mwatsatanetsatane mkulu.

Laser quenching imakhala ndi liwiro loziziritsa mwachangu komanso kachulukidwe kamphamvu kwambiri. Ndi ukadaulo woyeretsa komanso kuzimitsa mwachangu popanda kugwiritsa ntchito zoziziritsa kukhosi (mafuta, madzi, ndi zina).

1. Zida zozimitsira pafupipafupi zimakhala bwino kukana kuvala, kuuma kwakuya komanso kuuma kwakukulu kuposa kusanjikiza kozimitsa kwa laser. Choyipa chaukadaulo uwu ndikuti kuuma kwapamtunda kwa workpiece kumawonongeka pang’onopang’ono, ndipo nthawi zambiri kumafunikira makina otsatila kuti achire. Makina ozizimitsa othamanga kwambiri angagwiritsidwe ntchito kulimbikitsa mawonekedwe ovala ziwalo m’mafakitale otsatirawa: mafakitale a petrochemical, makina ndi zitsulo. Lili ndi zotsatira zabwino ndipo lapeza ubwino wa chikhalidwe ndi zachuma.
