Hauv kev tsim kho kev lag luam thiab kev siv tshuab,countersunk screwsyog dav siv, yam ntxwv ntawm lawv muaj peev xwm nkag mus tob rau hauv qhov chaw ntawm cov khoom thiab tuav ib tug du nto. Cov duab sib txawv ntawm countersunk screws, xws li plum blossom, hla, ncaj thiab hexagonal, tuaj yeem xaiv raws li kev xav tau.
Txawm li cas los xij, thaum siv countersunk screws, muaj qee qhov kev ceev faj tseem ceeb kom nco ntsoov:
Tsim nyog taper lub kaum sab xis: Thaum nthuav qhov, xyuas kom meej tias lub kaum sab xis yog 90 degrees los yog ze li sai tau rau 90 degrees. Yog tias lub kaum sab xis tsis ua raws li qhov yuav tsum tau ua, nws yuav cuam tshuam rau kev kho cov nyhuv ntawm cov ntsia hlau.
Xaiv qhov tsim nyog ntsia hlau loj: Yog tias lub thickness ntawm cov khoom ruaj khov yog nyias, nws raug nquahu kom xaiv cov ntsia hlau me me los yog txo qhov loj ntawm qhov loj kom tsim nyog.
Tsis txhob drilling skewness: Yog tias xav tau ntau qhov countersunk screws yuav tsum tau kho, xyuas kom meej qhov tseeb ntawm drilling kom paub meej qhov zoo nkauj tom qab sib dhos.
Ntxiv nrog rau kev ceev faj, daws qhov teeb meem ntawm xoobntsia hlaukuj tseem ceeb heev. Nov yog qee qhov uas feem ntau siv los tiv thaiv loosening kev daws teeb meem rau screws:
Mechanical anti loosening txoj kev: Qhov no suav nrog kev siv cov pins cais, tiv thaiv looseningcov ntxhua khaub ncaws, threading steel hlau ropes, thiab lwm yam. Cov txheej txheem no txhim khu kev qha thiab tsim nyog rau kev sib txuas tseem ceeb.
Kev sib txhuam los tiv thaiv loosening txoj kev: Siv gaskets,txiv ntseej, los yog anti drip kua nplaum rau ntawm threads ntawm screws. Anti-drip adhesive muaj siab adhesion thiab non-toxic khoom. Tom qab siv rau threads, nws muaj peev xwm muab super muaj zog adhesion, enabling txiv ntseej rau daim ntawv cog lus nrog screws los yog cov khoom threaded qhov kom ua tau super muaj zog fastening nyhuv, zoo tiv thaiv screws los ntawm loosening.
Txoj kev kaw ruaj ruaj: Cov txheej txheem no suav nrog qhov chaw vuam, riveting, kev sib txuas, thiab lwm yam. Txawm li cas los xij, cov txheej txheem no yuav ua rau cov xov fasteners puas thaum lub sij hawm disassembly txheej txheem thiab yog li tsis tuaj yeem rov qab siv dua.
Hauv cov ntsiab lus, thaum siv countersunk screws, nws yog ib qho tseem ceeb uas yuav tau xaiv qhov tsim nyog specifications thiab taper cov ces kaum, ua raws li txoj kev txhim kho kom raug, thiab ua raws li qhov tsim nyog los tiv thaiv loosening ntsuas raws li xav tau. Qhov no tuaj yeem ua kom muaj kev sib txuas ruaj khov thiab tiv thaiv kom tsis txhob xoob ntawm cov countersunk screws, thiab txhim kho kev nyab xeeb thiab kev ntseeg tau ntawm kev sib dhos.
