Kudula kwa Lawi - Gawo Loyamba mu Njira Yokhazikika Yamakina a Excavator

Anthu ambiri amaganiza kuti makina amangopanga, ndikuti zida zamakina odulidwa ndi manja ndi zida zamakina zimagwiranso ntchito mofanana. Kodi zikufananadi choncho? Osati kwenikweni. Tangoganizani chifukwa chake zida zamakina zopangidwa ku Japan ndi Germany ndizapamwamba kwambiri. Kuphatikiza pa zida zamakono zamakina, amadaliranso miyezo ndi njira zokhwima. Lero, tiyeni tiyambe ndi sitepe yoyamba: kudula lawi.

1.1 Chidule cha Njira

Kudula kwamoto ndiye gawo loyamba lopangira zinthu zopangira zida zopangira zida zofukula komanso gawo loyamba pakukonza mbale pamakina ambiri omanga. Cholinga chake chachikulu ndikugawanitsa bwino zitsulo zazikuluzikulu m'zigawo zosiyanasiyana kuti zipangidwe pambuyo pake, kuphatikizapo mbale zazikulu zakunja, mbale zowonjezera mkati, ndi mbale zapampando za trunnion, malinga ndi zofunikira za mapangidwe.

Izi zimagwiritsa ntchito zida zodulira mafuta a okosijeni a CNC, zomwe zimapanga lawi lotentha kwambiri pogwiritsa ntchito osakaniza a oxygen-acetylene kuti asungunuke pang'ono ndikusungunula mbale yachitsulo ya kaboni.

1.2 Kusintha kwa Chipangizo

● Makina odulira malawi a CNC (benchtop/gantry)
● Makina opangira ma pulogalamu ndi njira zowongolera (zotengera zojambula za CAD)
● Njira yoperekera mpweya wa oxygen ndi acetylene
● Kukweza tochi ndi gawo lowongolera kutentha kwa moto

1.3 Zinthu Zofunika

1.4 Njira

1) Kukonzekera musanadule

● Onetsetsani kuti mbale yachitsulo ndi miyeso ikugwirizana ndi zojambula;
● Chotsani mafuta, chinyezi, ndi dzimbiri pazitsulo.

2) Programming ndi typesetting

● Lowetsani mapangidwe a CAD mu dongosolo la CNC kudula;
● Kumanga zisa mwanzeru kuti mugwiritse ntchito bwino zinthu;
● Khazikitsani dongosolo lodulira, kuika patsogolo zigawo zing'onozing'ono ku zigawo zazikulu kuti muteteze kutentha kwa kutentha.

3) Kuwongolera zida

● Sanjani njira yolondola;
● Khazikitsani mphamvu ya gasi lamoto (0.4-0.6 MPa ya oxygen, 0.01-0.05 MPa ya acetylene);
● Sinthani kusiyana koyambirira pakati pa nyali yodula ndi mbale yachitsulo (3-5 mm).

4) Kuwombera kwamoto

● Kuyatsa kumatenthetsa mpaka pamene chinthucho chikuyatsira;
● Mutu wodula umayenda motsatira njira, pamene kudula kwamoto kumapitirira nthawi imodzi;
● Imasunga m'lifupi mwake (nthawi zambiri 2.5mm mpaka 4mm) kuteteza kuyaka kosiyana.

5) Kuyang'anira khalidwe

● Yang'anani m'maso mowongoka ndi ukhondo wa pamwamba;
● Gwiritsani ntchito ultrasound makulidwe gauge kutsimikizira kuya kwa kutentha komwe kumakhudzidwa ndi madera ofunika;
● Yang'anani kulolerana kwa magawo odulidwa (nthawi zambiri ≤± 1.5mm).

6) Pambuyo pokonza

● Chotsani pamanja zodula;
● Yeretsani sikelo ya oxide kuti mupewe ma pores omwe amawotcherera.

1.5 Mfundo Zaukadaulo ndi Kusamala

● Kuthamanga kwachangu kumayenderana kwambiri ndi makulidwe a mbale kuti ateteze m'mphepete mwake kuti asagwe kapena kuwotcha;

● Chitsulocho chiyenera kumangidwa mokhazikika kuti zisagwedezeke panthawi yodula zomwe zingayambitse kupatuka panjira yodulira.
● Pa mbale zochindikala zopitirira mamilimita 40, njira yowotchera moto yamitundu yambiri iyenera kugwiritsidwa ntchito kuti muwongolere kulimba kwa kerf.
● Sungani chiyero cha okosijeni cha ≥99.5%, apo ayi kusalala kwa malo odulidwa kudzakhudzidwa.
● Pakupanga, kusintha kwa kutentha kwa lawi kuyenera kuyang'aniridwa mu nthawi yeniyeni kuti musinthe chiŵerengero cha gasi mwamsanga.

The pamwamba ndi sitepe yoyamba Machining wa zomangamanga makina ofukula, lawi kudula.
