Yuav tsum tau sib dhos ua keYuav tsum tau siv raws li ib tug tiav set:DIN 6914 bolts + DIN 6915 txiv ntseej + DIN 6916 ntxhua khaub ncaws. Tsis txhob sib tov nrog tus qauv DIN934 txiv ntseej lossis cov tshuab ntxhua khaub ncaws.

Hwj chim chav kawm txwvDIN 6914 tsuas yog tsim rauChav Kawm 10.9. Tsis txhob hloov nrog 8.8 qib bolts rau kev sib txhuam- hom kev sib txuas. Ua ke nrog10 HV noob.

Txoj cai InstallationOb lub DIN 6916 ntxhua khaub ncaws yuav tsum: ib qho hauv qab lub taub hau, ib qho hauv qab txiv ntoo. Washer chamfer sab ntsib qhov chaw sib cuag.

Tightening TswjSiv calibrated torque wrench; nruj me ntsis raws li teev preload torque. Tsis txhob dhau- zawm (xov stripping / bolt breakage) los yog hauv qab - zawm (slip tsis ua hauj lwm). Ob -theem nruj (ua ntej- zawm + zawm zaum kawg) pom zoo rau cov qauv hlau.

Xov xwm xwm txheejKhaws cov xov kom huv, qhuav, tsis muaj xuab zeb, xeb, roj lossis roj. Tsis txhob siv cov roj nplua nyeem tshwj tsis yog pom zoo los ntawm kev tsim; lubrication hloov torque coefficient.

Xov xwm nthuav tawmTom qab zawm,2 ~ 3 tag nrho threads yuav tsum protrude tshaj lub txiv ntoo. Tsis pub muaj kev cuam tshuam xoom los yog cov xov protruding ntau dhau.

Cia & tuavTiv thaiv qhov chaw los ntawm xeb, cuam tshuam thiab xov puas ua ntej kev teeb tsa. Cov bolts / txiv ntseej puas tsis tuaj yeem rov qab siv dua.

Thaum nruj rau qhov teev preload, HV boltsyuav tsum tsis txhob rov siv dua.

Kev ceeb toom txheemDIN 6914 yog rho tawm qub German qauv; tam sim no European sib npaug yogTS EN 14399-4. Paub meej qhov kev lees paub nrog EU cov neeg siv khoom ua ntej.

Daim Ntawv Thov ScopeHaum rau kev sib txhuam-grip steel structural joints. Tsis pom zoo rau rotating hinge kev twb kev txuas.

 

 

 

• Ua kev soj ntsuam tsis tu ncua ntawm cov ntsia hlau txuas; tshawb xyuas corrosion, loosening, lossis puas rau lub taub hau taub hau / pob txha tawg.
• Rau cov txheej txheem tseem ceeb, ua qhov kev kuaj ua ntej lub sijhawm nrog cov cuab yeej tshaj lij; hloov bolts tam sim ntawd yog tias pom tias qhov khoom poob los yog cov khoom qaug zog.
• Tsis txhob ua ib qho kev ua haujlwm thib ob (sib tsoo, vuam, drilling) ntawm lub bolts tom qab kev teeb tsa, vim qhov no yuav ua rau lawv cov khoom puas tsuaj.

 

 

Ntim Cov Kev Xaiv

Cov ntim me me: ntim cov hnab yas (nrog rau cov roj los tiv thaiv- xeb) + cov thawv me me (cim nrog cov lus qhia / qib / ntau).

• Ntim Ntim: Corrugated cartons + ntoo pallets, hlau nruas (rau siab - kev tiv thaiv corrosion).
• Customized ntim: Cov ntawv ntim ntim nrog cov lej ua haujlwm, tiv thaiv- lub hnab ntim xeb xeb, thiab ruaj khov- ntim ntim rau ntawm - qhov kev tsim kho kom zoo.Txhua lub ntim yog tsim los tiv thaiv cov bolt xov / spline puas thiab corrosion thaum thauj thiab khaws cia.

Order Flexibility

• Txhawb nqa ntau thiab qhov project-raws li kev txiav txim customized; hloov tau MOQ (yam tsawg kawg nkaus kom muaj nuj nqis) rau me me -batch project xav tau.
• Cov nqe lus kev thauj mus los sib tham (FOB, CIF, EXW, DDP) thiab cov sij hawm xa tuaj kom haum rau cov neeg siv khoom siv sijhawm ua haujlwm.
• Muab qhov rooj-rau- qhov chaw xa khoom rau cov haujlwm loj- nplai engineering kom ntseeg tau ntawm - cov khoom siv hauv tsev.

Certification thiab Quality Assurance

• Peb DIN6914 HEAVY HEX bolts tau lees paub rau thoob ntiaj teb kev tswj hwm cov txheej txheem:ISO9001: 2015thiabIATF16949: 2016, thiab ua raws li EN14399 tus qauv kev cai.
• Tag nrho cov khoom raug kuaj 100% Hoobkas: tensile lub zog, yield zog, hardness, tawg groove torque raug, thiab xov precision xeem; muab ib daim ntawv qhia txog kev soj ntsuam zoo rau txhua pawg.
• Peb muab sijhawm ntev -cov khoom lag luam lav tau zoo thiab ua tiav tom qab- kev pabcuam kev muag khoom, suav nrog ua ntej- kev muag khoom tsim qauv tsim, hauv - muag ntawm - qhov chaw qhia kev qhia, thiab tom qab- kev muag khoom zoo taug qab thoob plaws hauv txoj haujlwm.
• Muab cov kev cai uas tsis yog -txheej txheem nruj tswj bolt daws rau tshwj xeeb steel qauv engineering yuav tsum tau (xws li, ncua shank, tshwj xeeb nto kho).
