Ihe ọmụma bụ isi nke a na-ejikarị eme ihe nke fasteners

1. Fasteners a na-ejikarị gụnyere:arịlịka wedge(ETA WEDGE ANCHOR), eriri eri, ihe mkpuchi hex, hex nut, ewepụghị ihe nzacha, ihe nkwado fotovoltaic

2. Labeling nke fasteners

M6 na-ezo aka na n'ọnụ ọnụ dayameta d nke eri (isi dayameta nke eri)

14 na-ezo aka na eriri nwoke ogologo L nke eriri

Dị ka: hex head bolt M10*1.25*110

1.25 na-ezo aka na pitch nke eri ahụ, na eri dị mma ga-akara akara. Ọ bụrụ na ewepụrụ ya, ọ na-egosi eriri na-enweghị isi..

3. Performance larịị nke fasteners

Bolt arụmọrụ akara ule na-ekewa n'ime ihe karịrị 10 akara ule dị ka 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, wdg, n'etiti nke bolts nke ọkwa 8.8 na n'elu na-mere nke ala carbon alloy ígwè ma ọ bụ n'elu. ọkara carbon ígwè na e okpomọkụ mesoo (quenching, tempering, wdg) ọkụ), nke a na-akpọkarị bolts ike dị elu, na ndị ọzọ na-akpọkarị bolts nkịtị. Akara ọkwa arụmọrụ bolt nwere akụkụ abụọ nke ọnụọgụgụ, nke na-anọchi anya uru ike tensile ọnụ na ntinye ike nke ihe bolt. Ọnụọgụ dị n'ihu ntụpọ ntụpọ na-anọchi anya 1/100 nke oke ike nke ihe ahụ, na ọnụọgụgụ mgbe akara nrịbasị ahụ na-anọchi anya 10 ugboro nha nke oke mkpụrụ na njedebe ike nke ihe ahụ.

Ọmụmaatụ: arụmọrụ larịị 10.9 elu-ike bolts, ọ pụtara bụ:

1. The nominal tensile ike nke bolt ihe ruru 1000MPa;

2. Ọnụ ego nke ihe mkpuchi bụ 0,9;

3. The nominal mkpụrụ ike nke bolt ihe ruru 1000 × 0.9 = 900MPa;

Ihe akara ngosi bolt pụtara bụ ọkọlọtọ mba ụwa. Bolts nke otu ọkwa arụmọrụ nwere otu arụmọrụ n'agbanyeghị ihe dị iche na ihe ha na mmalite ha. Naanị ọkwa arụmọrụ nwere ike ịhọrọ maka imewe.
