Ukadaulo mphero wa bolodi dera CNC mphero makina kumaphatikizapo kusankha malangizo a chida, njira chipukuta misozi, malo njira, dongosolo chimango, ndi malo odulira, amene ali mbali zonse zofunika kuonetsetsa kulondola kwa mphero. . Zotsatirazi ndi PCB bolodi njira mphero mwachidule ndi Jie Duobang pcb mwatsatanetsatane kulamulira njira ndi njira.

Njira yodulira ndi kubweza:

Pamene wodula mphero akudula mu mbale, imodzi mwa nkhope zomwe ziyenera kudulidwa nthawi zonse zimayang’ana pamphepete mwa mphero, ndipo mbali inayo nthawi zonse imayang’ana pamphepete mwa mphero. Yoyambayo imakhala yosalala pamwamba kuti ikonzedwe komanso yolondola kwambiri. Chophimbacho chimakhala chozungulira nthawi zonse. Choncho, kaya ndi makina a CNC mphero okhala ndi kayendedwe ka spindle kokhazikika kapena kayendedwe ka spindle kokhazikika, pamene mphero yakunja ya bolodi yosindikizidwa, chidacho chiyenera kusunthidwa mosiyana.

Izi nthawi zambiri zimatchedwa up milling. Kukwera mphero kumagwiritsidwa ntchito pogaya chimango kapena kagawo mkati mwa bolodi. Kulipira mphero ndi pamene chida cha makina chimangoyika mtengo wamtengo wapatali panthawi ya mphero, kotero kuti wodula mphero amachotsa theka la mphero yodula pakati kuchokera pakati pa mzere wa mphero, ndiko kuti, mtunda wa radius, kotero kuti mawonekedwe a mphero zimayikidwa ndi pulogalamu kukhala zogwirizana. Panthawi imodzimodziyo, ngati chida cha makina chili ndi ntchito yobwezera, muyenera kumvetsera malangizo a malipiro ndi lamulo la pulogalamuyo. Ngati lamulo la chipukuta misozi likugwiritsidwa ntchito molakwika, mawonekedwe a bolodi ladera adzakhala ocheperako kapena ocheperako ndi kutalika ndi m’lifupi mwake mwa mphero wodula.

Njira yoyikira ndi malo odulira:

Pali mitundu iwiri ya njira zoyika; imodzi ndi malo amkati, ndipo ina ndi malo akunja. Kuyikanso ndikofunikira kwambiri kwa amisiri. Nthawi zambiri, dongosolo loyikira liyenera kutsimikiziridwa panthawi yopanga gulu ladera.

Kuyika kwamkati ndi njira yapadziko lonse lapansi. Zomwe zimatchedwa kuika mkati ndikusankha mabowo okwera, mabowo a pulagi kapena mabowo ena omwe si azitsulo mu bolodi losindikizidwa ngati mabowo oyika. Malo ogwirizana a mabowowo ndi kukhala pa diagonal ndi kusankha dzenje lalikulu la m’mimba mwake momwe mungathere. Mabowo azitsulo sangathe kugwiritsidwa ntchito. Chifukwa kusiyana kwa makulidwe a plating wosanjikiza mu dzenje kumakhudza kusasinthika kwa dzenje lomwe mwasankha, ndipo nthawi yomweyo, ndizosavuta kupangitsa kuti plating wosanjikiza mu dzenje ndi m’mphepete mwa dzenje liwonongeke. pamene gulu likutengedwa. Pansi pa chikhalidwe cha kuonetsetsa kuti malo a bolodi losindikizidwa, chiwerengero cha zikhomo chidzakhala chochepa.

Nthawi zambiri, bolodi yaying’ono imagwiritsa ntchito mapini awiri ndipo bolodi yayikulu imagwiritsa ntchito mapini atatu. Ubwino wake ndikuyika kolondola, kusinthika pang’ono kwa mawonekedwe a bolodi, kulondola kwambiri, mawonekedwe abwino, komanso liwiro la mphero. Zoipa: Pali mitundu yambiri ya mabowo pa bolodi yomwe imayenera kukonza zikhomo za diameter zosiyanasiyana. Ngati palibe mabowo oyika pa bolodi, zimakhala zovuta kukambirana ndi kasitomala kuti muwonjezere mabowo mu bolodi panthawi yoyambira. Panthawi imodzimodziyo, kasamalidwe kosiyana ka ma templates a mphero pamtundu uliwonse wa bolodi ndizovuta komanso zodula.

Kuyika kwakunja ndi njira ina yoyikira, yomwe imagwiritsa ntchito mabowo oyika kunja kwa bolodi ngati mabowo oyika mbale. Ubwino wake ndikuti ndizosavuta kuyendetsa. Ngati zomwe zidapangidwa kale zili zabwino, nthawi zambiri pamakhala mitundu pafupifupi 15 ya ma tempulo amphero. Chifukwa chogwiritsa ntchito mawonekedwe akunja, bolodi silingadulidwe ndikudulidwa nthawi imodzi, apo ayi bolodi lozungulira ndilosavuta kuwononga, makamaka jigsaw, chifukwa chodula mphero ndi wosonkhanitsa fumbi adzatulutsa bolodi, ndikupangitsa gulu ladera. kuti awonongeke ndipo chodula mphero kuti chiswe.

Pogwiritsa ntchito njira ya segmented mphero kusiya mfundo olowa, choyamba mphero mbale. Pamene mphero yatha, pulogalamuyo imayima ndipo mbaleyo imakonzedwa ndi tepi. Gawo lachiwiri la pulogalamuyi likuchitidwa, ndipo mfundo yolumikizana imachotsedwa ndi kubowola 3mm mpaka 4mm. Ubwino wake ndikuti template ndiyotsika mtengo komanso yosavuta kuyendetsa. Ikhoza kugaya matabwa onse ozungulira popanda mabowo oyikapo ndikuyika mabowo pa bolodi. Ndi yabwino kwa amisiri ang’onoang’ono kusamalira. Makamaka, kupanga kwa CAM ndi ogwira ntchito ena oyambilira kumatha kukhala kosavuta ndipo gawo lapansi limatha kukonzedwa nthawi yomweyo. Mtengo wogwiritsa ntchito. Choyipa ndichakuti chifukwa chogwiritsa ntchito kubowola, bolodi laderali lili ndi mfundo zosachepera 2-3 zomwe sizili zokongola, zomwe sizingakwaniritse zosowa za makasitomala, nthawi yophera ndi yayitali, ndipo mphamvu ya ogwira ntchito ndi yayikulu pang’ono.

Frame ndi malo odulira:

Kupanga chimango ndi kwa kupanga koyambirira kwa bolodi ladera. Kukonzekera kwa chimango sikungokhudza kufanana kwa electroplating, komanso kumakhudza mphero. Ngati mapangidwewo sali abwino, chimango ndi chosavuta kupunduka kapena tizidutswa tating’ono tating’ono timapangidwa panthawi yamphero. Zing’onozing’ono, zotsalira zomwe zimapangidwa zimatsekereza chubu kapena kuswa chodula chothamanga kwambiri chozungulira. Kupindika kwa chimango, makamaka poyika mbale ya mphero kunja, kumapangitsa kuti mbale yomalizidwayo iwonongeke. Kuonjezera apo, kusankha malo odulira ndi ndondomeko yowonongeka kungapangitse chimango Kukhalabe ndi mphamvu zambiri komanso kuthamanga kwambiri. Ngati kusankha sikuli bwino, chimango chimapunthwa mosavuta ndipo bolodi losindikizidwa limachotsedwa.

Magawo amilling process:

Gwiritsani ntchito chodula cha simenti ya carbide kuti mupe mawonekedwe a bolodi losindikizidwa. Liwiro lodula la chodula mphero nthawi zambiri ndi 180-270m/min. Njira yowerengera ili motere (pongowona):

S=pdn/1000 (m/mphindi)
