Likumira - ndi chiyani ichi?

The ndondomeko zamakono chosintha zamitundu yosiyanasiyana mbali zambiri osati popanda mtundu wa Machining, onse likumira. Tamasulira kuchokera ku mawu German limatanthauza "malo", "kuzamitsa". Kukhala yokwanira bwino, ndi njira, imene kumawonjezera awiri a m'maenje. Iwo angayerekezedwe ndi reaming lapansi. Countersinking - opaleshoni makina, amene anachita pa wotopetsa mabowo, luso ndi olondola ndipo pamwamba.

kulandira mabowo

Kuti timvetse bwino zimene likumira, muyenera kukhala lingaliro bwanji kuti mabowo mwatsatanetsatane. Tiyerekeze preform m'pofunika kubowola dzenje la kalasi lachisanu yolinganizika awiri a mamilimita 12.

Izi zimafuna pobowola makina ndi chida 3 ntchito: kubowola, countersink ndi aone. Aliyense ndime zimenezi lakonzedwa kusamalira, chifukwa reaming kubowola, atumiza - opaleshoni zofanana kwambiri ndi mzake. Makamaka kuchita workpiece ntchito kubowola dzenje, koma m'mimba mwake yake idzakhala zochepa kwambiri kusiyana ndi chofunika, kuti theka - 6 mm.

Izi wosemera. Kenako, m'pofunika ream countersink awiri 12 mm (kumaliza ntchito). Komanso, pakati pobowola adzapereka 7 mwatsatanetsatane kalasi.

Kuti kutsegula 5 kalasi, muyenera ntchito jambulani. Iwo adzapereka zofunika kukula malire ndi ankamvetsa - kutsirizitsa ndi kuwamaliza Machining dzenje. Reaming ndi countersinking zambiri ntchito pa awiri chomwecho, koma malire osiyana kukula, ndipo monga zikulilima imapereka kalasi m'munsi molondola, titsate analamula anasankha molondola mkulu.

Reaming ndi countersinking

Nthawi zambiri mfundo izi ali osokonezeka ndi mzake chifukwa chakuti ali ofanana kwambiri mayina. Komabe, ngati likumira - njira imene countersink kukolowola kuya lonse la processing countersink otchedwa pamwamba.

M'pofunika kupanga M'kati mwa countersunk mutu yolusa zinthu (akapichi, rivets, zomangira). Countersink - chida chamfering amasiyana ndi mawonekedwe countersink mbali ya ntchito.

Zida ndi mitundu countersink

Basi kudula chida, countersink zimagawidwa ndi mtundu wa zomangamanga, mawonekedwe ndi mtundu wa mankhwala, komanso nkhani lomwe anapanga.

Popeza chida ali mkulu kuuma, kawirikawiri zikhale za liwiro zitsulo mkulu Komabe, nthawi zambiri Tingaone ndi constructional doped countersink (40X) ndi mpweya (ST45) aloyi.

Likumira - izo kusalaza ndi yoyeretsa ya pamwamba, kotero chida iyoyomwe ambiri kudula m'mbali. Countersinks kungakhale precast mchira ndi masamba detachable, mchira mu chidutswa chimodzi, kukankha-ndi kukankhira-yofunika magulu.

Kuwaona pamaso pa dzuwa, ndiye, ndithudi, zida yodziyimira payokha ndi okwera mtengo kwambiri, koma moyo wawo ndi yaitali, kuyambira m'mphepete mwa zosalongosoka akhoza m'malo.

M'litali ndi m'mimba mwake

Popeza pobowola pa, reaming - zimachitika ofanana ndithu, ndi kubowola pang'ono (makamaka mwauzimu akufa pochita) ndi countersink pakupezeka dongosolo lomwelo. Aliyense chida ali ndi kudula gawo limenelo mwachindunji akupanga dzenje mu gawo.

kusiyana ndi kuti palibe countersink yopingasa zotsogola, koma pali kuchokera mano atatu sikisi. mbali ntchito tichipeza n'zotsimikizira ndi kudula zigawo a. Kutalika chimadalira pa mozama za reaming chachiwiri. The n'zotsimikizira - ndi maliboni kotenga pamodzi akadaulo. m'lifupi awo zimadalira awiri a countersink (0.8-2.5 mm) ndi kutalika - 0.2-0.9 mm.

Reaming - opaleshoni makina, ofanana reaming lapansi. Ngati cholinga chake ndi inabala dzenje kwa analamula, m'mimba mwake countersink amasankhidwa ang'onoang'ono, anapatsidwa gawo pa ntchito otsiriza kuwamaliza. Komanso, popeza chofunika mwatsatanetsatane chida n'chozama kupitirira kuti kuyang'ana makhalidwe mtheradi zolakwika kungakhale zambiri.

Mu mulandu wina, reaming mabowo - ichi ndi kuwamaliza otsiriza chofunika magawo ndi kulolerana 11, 12 sitandade. Ndiye chida amusankha zochokera kusokonezeka ndi kusunga kwa avale, ndi m'mimba mwake ake ayenera kufanana ndi awiri a una.

Engineering ndi mamangidwe

Kuti awiri mabowo ndi kunali koyenera molondola zotheka, kugwira ntchito projecting countersink. Choncho tikhoza kupeza pazipita ndi osachepera awiri chida kofunika kudziwa zinthu ndi kudula mbali kuchita mawerengedwe a zinthu kudula.

zinthu zofunika zokhudza pazipita ndi osachepera mfundo - izo chofunika kvalitet. Mwachitsanzo, m'pofunika kuchita kumaliza countersinking mabowo pa 85 mamilimita awiri ndi Qualitet H11. Yachokera minda mabowo tolerances matebulo pa kukula mwadzina kuchokera 1 mpaka 500 mm, kuti khalidwe kalasi 11 (kwa diameters ku 80 mamilimita kwa 120 mm) kulolerana wakumunda: phindu chapamwamba - "220" ndipo m'munsi - "0", i.e. 85 ²²⁰ mm. The awiri pazipita reams mabowo akhoza musalumphe 85,22 mm, ndi osachepera - 85 mm.

Pankhaniyi, ooneka enieni kulolerana - kusiyana pakati D _Max ndi D _Mph, i.e. zidzakhala 0,22 mm. Ngati ife kulankhula za banja, ndiye mabowo adzakhala anaona awiri incorrigible kuposa 85,22 mamilimita kukonzedwa - zosakwana 85 mm.
