Intloko yesilinda yinxalenye ebalulekileyo yesakhiwo se-injini. Umngxuma oyintloko we-oil passage yingxenye ebalulekileyo yentloko ye-cylinder. Ukuba umngxuma we-oyile ophambili unee-burrs, ii-burrs ziya kuvala i-tappet ye-hydraulic njengoko i-oyile ingena kumngxuma we-HVA, ibangele ukuba ingaphumeleli. , Oku kwenza ukuba i-valve yentloko ye-cylinder ingakwazi ukuvala, ibangela ukuba ibhloko ye-cylinder ingabikho iisilinda. Ngoko ke, kuyimfuneko ukuqinisekisa ukuba akukho burrs ehlala kumngxuma oyintloko wokuhamba.

Izizathu ze-burrs kwimingxuma yeoli ye-cylinder head:

Inkqubo yokwembiwa komngxuma oyile wokuhamba kwentloko ye-cylinder yinkqubo yokucheba yokutyibilika eveliswa yi-drill bit drill ecudisa i-workpiece. Ngenxa yesakhiwo kunye nokuhlelwa kwendlela yeoli ngokwayo, imida, iikona, kunye neekona ekudibaneni kweepaseji ezimbini okanye ngaphezulu zeoli zenziwe. Umphetho uya kubonakala i-deformation enkulu yeplastiki, i-drill bit kunye ne-workpiece iya kuba nenkqubo yokwahlula kwi-intersection, ekulula kakhulu ukuvelisa i-burrs.

Iziphumo eziphambili ze-cylinder head hole burrs zezi:

1. Ukuchaphazela ukuchaneka kwe-dimensional ye-workpiece;
2. Ukuchaphazela okanye ukuphazamisa ukuchaneka komlinganiselo we-workpiece;
3. I-burrs iyawa ngexesha lokucubungula okanye ukuthutha, okuchaphazela ukucoceka kwamacandelo;
4. Ngethuba lokufakwa kwenkqubo, i-burr iyawa kwaye kukho umngcipheko wokhuseleko lwemikrwelo kunye nokusikeka;
5.Ngexesha lokucutshungulwa okulandelayo, i-burr iyawa kwaye ibangela ukulahlekelwa kwenxalenye (inxalenye engathandekiyo), ebangela ukuba inxalenye ikhutshwe;
6. Iburr iyawa, kwaye iburr iwela phakathi kwecamshaft kunye nesigqubuthelo secamshaft, okukhokelela ekugugeni okungaqhelekanga kwecamshaft kunye nesigqubuthelo secamshaft okanye nokutshixa kwecamshaft;
7. I-burr iwela kwindlela ye-VVT kwaye ibangela umatshini ukuba udibanise kwaye ungaphumeleli;
8. Ukuchaphazela umphumo wokuthambisa, ngaloo ndlela kuchaphazela ukusebenza kwe-injini.
