Chosinthika wrench: zaka 125 mu nyumba

Mwini aliyense wa nyumba ali ndi mndandanda wa zida zofunikira ndi zogwirizana kumuthandiza kuthana ndi wovulala, pamene mwadzidzidzi "zahlyupal mphuno" chosakanizira, "capricious" chitoliro madzi, kapena mtedza aliyense amabweretsa chisokonezo mu chikhalidwe momasuka wa kunyumba. akonzedwa izi zonse kumaphatikizapo wrench chosinthika. Ndi chida ichi - yaying'ono, yosavuta kugwiritsa ntchito ndi yosavuta - amalola kumangitsa nati kwathunthu za kukula kulikonse, popanda kusintha chida. Pa gawo lino la moyo, pali mitundu yosiyanasiyana ya chipangizo ichi, chimene amasiyana Chrixitu mu mawonekedwe, chuma ndi katundu kinematic.

Chosinthika wrench kale - tichipeza zaka mazana makumi awiri ndi asanu. The zinachitika kwa chilengedwe cha chida ichi chinakhala ngati kuti zingamvekere zachilendo, dzanja anthu. Inde, ndi gawo ili la thupi anali kutsogolera kwa chilengedwe mu 1888 yoyamba ya zida zotere. Ndipo kale ndiye, mu zinachitika wake unaperekedwa mafungulo ena onse - makina, kuikira Self-clamping, chosinthika wrenches.

Mfundo chida uyu anabwera ndi Yu P. Yuhanssonu -. Chiyambi Swiss. Zochokera chakuti munthu amagwiritsa ntchito dzanja, akufuna kutenga chinthu chilichonse kukula, akuti kuti inu mukhoza kulenga izo ngati chida chomwe kukhala oyenera mtedza zamitundu yonse. Zikomo lingaliro limeneli, ndipo panali wrench chosinthika amatchedwa "chitsulo dzanja."

Popeza akukonza zambiri zosintha ndi patsogolo, chida ichi wakhala masiku athu, kukhala monga singasiyanitsidwe kunyumba ntchito kulemekezedwa zedi wa ambuye onse.

chipangizo Izi Nthawi zambiri mitundu iwiri ya zitsulo: mpweya zitsulo, munali palibe zina monga chromium, manganese, vanadium, ndi doping (ndi Kuwonjezera chromium, titaniyamu, pakachitsulo, faifi tambala, etc.).

"Iron dzanja" zimasiyana osati mankhwala awo zikuchokera, komanso ndi processing njira: zingakhale makina kapena matenthedwe.

Pofuna kuteteza wrench ku dzimbiri, iwo ataphimbidwa ndi sitima zapadera: chrome, okusayidi kapena phosphorous. zida zamakono zambiri zosintha ndi mitundu, amene ali omasuka kuposa kale.

Chifukwa zokutira rubberized ndi oyika pulasitiki, iwo angagwiritsidwe ntchito ngakhale pa kutentha boma ziro. Komabe, cholimba kwambiri adakali ochiritsira makiyi zitsulo.

Chosinthika wrench tichipeza zigawo zitatu: a chogwiririra ali ndi Ine woboola pakati mtanda gawo, limagwirira nyongolotsi siponji. Amodzi nsagwada lonse la zida za mzere kuti amalola kuti anapereka mtengo wolakalakika za "pakhosi". Ziyenera adzanyamula kukumbukira kuti kutalika kwa chogwirira zimadalira kukula pazipita nati, kwa ntchito imene angathe "kutenga" chinsinsi.

Waukulu ulamuliro kusungiramo chida ndi kuyeretsa kuti kuchokera ku dothi. kuphweka Izi a kukonza kwake, ntchito zake zosiyanasiyana, ndi chomasuka ntchito kupanga chipangizo ichi bwenzi lalikulu la kuikira aliyense, ndipo okonza ndi anthu wamba, amene amati ndi mwini nyumba.
