Ingcaciso yeMveliso

Ukuthotyelwa okusemgangathweni:Uhlobo lwe-I Cross Recessed Pan Screws luhambelana neenkcukacha ezingqongqo ezichazwe kwi-ASME B 18.6.3 - 2013, ziqinisekisa ukungaguquguquki kunye nokuhambelana kuzo zonke izicelo. Ukudibana nemigangatho ye-ASTM F837 kunye ne-F468, ezi zikrufu ziqinisekisa ukuthembeka kunye nokusebenza.

Uyilo lwentloko yePan:Eyenziwe ngobunjineli bentloko ye-pan, ezi zikrufu zinika imbonakalo ephantsi kunye ne-flat bearing surface. Olu luyilo lubonelela indawo yoqhagamshelwano eyaneleyo yokuhambisa amandla omthwalo, ukuqinisa ukuzinza kunye nokuthintela umonakalo ongaphezulu.

Ukuwela Recessed Drive:Iquka i-cross recessed drive, ezi zikrufu ziququzelela ukufakwa lula kunye nezixhobo ezihambelanayo. I-recessed drive inciphisa ukutyibilika ngexesha lokuqina, iqinisekisa ukuqina okukhuselekileyo kunye nokunciphisa umngcipheko womonakalo kwintloko ye-screw.

Usetyenziso Oluguquguqukayo:Uhlobo lwe-I Cross Recessed Pan Head Screws lufanelekile kuluhlu olubanzi lwezicelo, kubandakanywa i-electronics, umatshini, kunye nendibano yefenitshala. Uyilo lwabo oluguquguqukayo kunye nokusebenza okuthembekileyo kubenza babaluleke kakhulu kwiimfuno ezahlukeneyo zokuzila.

⑥, Ubude beScrew somatshini woMsonto
1) Ubungakanani No.5 kunye nomncinci.
Izikrweqe zobude obuqhelekileyo obulingana needayamitha ezithathu kwaye ezimfutshane ziya kuba nemisonto epheleleyo eyolulela phakathi kwenowuthi enye (umsonto)
ukuthwala ubuso bentloko, okanye kufutshane, ukuba kunokwenzeka. Ubude obuqhelekileyo obungaphezulu kwedayamitha ezintathu, ukuya kuthi ga kunye nokubandakanya i-1-1/8 ngaphakathi
Imisonto egcweleyo enwenwela ukuya kuthi ga kwimisonto emibini (imisonto) kumphezulu othwele intloko, okanye kufutshane, ukuba kunokwenzeka. Izikrufu ezinde
ubude begama buya, ngaphandle kokuba kuchazwe ngolunye uhlobo, bunobude obuncinane bomsonto opheleleyo we-1 kwi.
2) Ubungakanani No.6 kunye nomncinci.
Izikrweqe zobude obuqhelekileyo obulingana needayamitha ezithathu kwaye ezimfutshane ziya kuba nemisonto epheleleyo eyolulela phakathi kwenowuthi enye (umsonto)
ukuthwala ubuso bentloko, okanye kufutshane, ukuba kunokwenzeka. Ubude obuqhelekileyo obungaphezu kweedayamitha ezintathu, ukuya kuthi ga kunye nokubandakanya u-2 ngaphakathi
Imisonto egcweleyo enwenwela ukuya kuthi ga kwimisonto emibini (imisonto) kumphezulu othwele intloko, okanye kufutshane, ukuba kunokwenzeka. Izikrufu ezinde
ubude begama buya kuba nobude obuncinane bomsonto opheleleyo we-1.5 ngaphakathi ngaphandle kokuba kuchazwe ngenye indlela.
⑦,Isixhobo sokuKhhula kumatshini
I-1) intsimbi ye-carbon ephantsi engaphathwa ngobushushu, efana ne-1006 nge-1038
2) Xa kucacisiwe umatshini oqinileyo isikrufu, ziya kwenziwa ukusuka ezantsi okanye medium carbon steel, ezifana 1018 ngokusebenzisa 1038, kunye okanye ngaphandle boron, ngokusebenzisa-lukhuni ukuya Rockwell C25-38
