Mu 1953, Pulofesa Dr Gilbert Waninger wa ku Germany anatulukira njira yoyamba padziko lonse yokokera zitsulo.Dr Waldrich, yemwe ali ndi kabelschlepp jiabora, akukhulupirira kuti drag chain ndi msika watsopano, womwe ungapangitse kufunika kwakukulu.Anayamba kulimbikitsa * ma chain chain kumsika mu 1954.
Tsopano zitsanzo zambiri zoyambirira zokoka zitsulo zakonzedwa kuti zikhale zamitundu yonse yazitsulo ndi pulasitiki, zomwe zimagwiritsidwa ntchito kwambiri m'madera ambiri.Kampani ya Kabelschlepp jiabora yapanga bwino zina: Portable drag chain, 3D drag chain ndi unyolo wosalumikizana.Lingaliro zaka zoposa 50 zapitazo linapanga msika waukulu wamakono.
Nthawi zambiri amagwiritsidwa ntchito poteteza zida zamakina, mapaipi a mpweya, mapaipi amafuta, mapaipi okoka, ndi zina zambiri.
Kugwiritsiridwa ntchito kwa unyolo wokokera kunayambira ku Germany poyamba, ndiyeno dongosololi lidanenedwa ndikupangidwa ku China.
Tsopano unyolo wokokera wakhala ukugwiritsidwa ntchito kwambiri pa makina opangira makina, omwe amateteza chingwe ndikupangitsa chida chonse cha makina kukhala chokongola kwambiri.
Kokani unyolo, payipi yachitsulo yamakona anayi, manja oteteza, mavuvundikiro ndi payipi yachitsulo yokhala ndi pulasitiki zonse ndizinthu zoteteza chingwe.Kokani unyolo agawidwa mu zitsulo kuukoka unyolo ndi pulasitiki kuukoka unyolo.Unyolo wokokera zitsulo umapangidwa ndi chitsulo ndi aluminiyamu ndipo ukhoza kusinthidwa mwamakonda.Unyolo wa pulasitiki umadziwikanso kuti unyolo wa engineering ndi tcheni cha tank.
Unyolo wokoka ukhoza kugawidwa mu unyolo wokoka mlatho, unyolo wotsekedwa bwino ndi unyolo wotsekedwa wotsekedwa malinga ndi malo ogwiritsira ntchito ndi zofunikira zogwiritsira ntchito.
Kugwiritsa ntchito ndi mawonekedwe a unyolo wa pulasitiki
(1) Ndi oyenera nthawi ya zoyenda reciprocating, ndipo akhoza traction ndi kuteteza anamanga-zingwe, mapaipi mafuta, mapaipi gasi, mipope madzi, etc.
(2) Gawo lililonse la unyolo wokoka likhoza kutsegulidwa kuti lithandizire kukhazikitsa ndi kukonza.Phokoso lochepa komanso kukana kuvala panthawi yoyenda, ndipo limatha kuyenda mothamanga kwambiri.
(3) Unyolo wokoka wagwiritsidwa ntchito kwambiri pazida zamakina a CNC, zida zamagetsi, makina amwala, makina agalasi, makina a khomo ndi zenera, makina opangira jakisoni, manipulator, zida zonyamulira zolemera kwambiri, nyumba yosungiramo zinthu zodziwikiratu ndi zina zotero.
Kapangidwe ka unyolo wa pulasitiki
(1) Maonekedwe a tcheni chokokera ali ngati tcheni cha thanki, chomwe chimapangidwa ndi maulalo ambiri a mayunitsi, ndipo maulalowo amazungulira momasuka.
(2) Kutalika kwamkati, kutalika kwakunja ndi phula la mndandanda womwewo wa maunyolo amakoka ndi ofanana, ndipo m'lifupi mwake ndi kupindika radius r ya unyolo wokoka akhoza kusankhidwa mosiyana.
(3) Ulalo wa unyolo wa unit umapangidwa ndi tcheni chamanzere ndi kumanja ndi mbale zakumtunda ndi zakumunsi.Ulalo uliwonse wa unyolo wokokera ukhoza kutsegulidwa kuti ugwirizane ndi kutha popanda ulusi.Mukatsegula chivundikirocho, chingwe, chitoliro chamafuta, chitoliro cha mpweya, chitoliro chamadzi, ndi zina zotere zitha kuyikidwa mu unyolo wokoka.
(4) Olekanitsa angaperekedwenso kuti alekanitse malo mu unyolo ngati pakufunika.
Basic magawo a pulasitiki kukokera unyolo
(1) Zida: nayiloni yolimbitsa, yothamanga kwambiri komanso yolemetsa, kulimba kwabwino, kusungunuka kwapamwamba komanso kukana kuvala, kutentha kwamoto, kugwira ntchito kosasunthika pamtunda komanso kutentha pang'ono, ndipo kungagwiritsidwe ntchito panja.
(2) Kukaniza: kugonjetsedwa ndi mafuta ndi mchere, ndipo kumakhala ndi asidi ndi zamchere.
(3) Malinga ndi liwiro la ntchito ndi mathamangitsidwe.
(4) Moyo wogwira ntchito.
