Nigute imyitozo ikorwa? Ni ibihe bibazo bizahura nabyo mugutunganya imyitozo? Kubijyanye nibikoresho bya drillage nibiranga? Ukora iki mugihe imyitozo yawe yananiwe?
Nka gikoresho gikunze kugaragara mu gutunganya umwobo, bits ya drill ikoreshwa cyane mubikorwa byo gukanika imashini, cyane cyane mugutunganya ibyobo mubice nkibikoresho byo gukonjesha, amabati y'ibikoresho bitanga amashanyarazi, hamwe na moteri ikora. Porogaramu ni nini cyane kandi ni ngombwa. Uyu munsi, Porofeseri w’ubukanishi yasanze iki cyegeranyo cya bito kubantu bose kurubuga rwa WeChat. Ibyo ukeneye byose biri hano!
Ibiranga gucukura
Imyitozo isanzwe ifite impande ebyiri zingenzi. Mugihe cyo gutunganya, imyitozo iragabanuka mugihe kizunguruka. Inguni ya rake ya biti yiyongera kuva kumurongo wo hagati ugana kumpera yinyuma. Umuvuduko wo kugabanya imyitozo ya biti wiyongera uko ugenda wegera uruziga rwo hanze, kandi umuvuduko wo kugabanya ugabanuka ugana hagati. Umuvuduko wo kugabanya imyitozo ya biti yo kuzenguruka ni zeru. Igice cya chisel ya biti ya drill giherereye hafi yumurongo wikizunguruka, impande ya chisel ifite impande nini zifasha inguni, nta mwanya wa chip, kandi umuvuduko wo gukata ni muke, bizabyara imbaraga nini zo kurwanya axial. Niba inkombe ya chisel ari hasi kugirango wandike A cyangwa wandike C muri DIN1414, kandi gukata hafi yumurongo wo hagati bifite inguni nziza ya rake, kurwanya gukata birashobora kugabanuka kandi imikorere yo gukata irashobora kunozwa kuburyo bugaragara.
Ukurikije imiterere y'ibikorwa bitandukanye, ibikoresho, imiterere, imikorere, nibindi, imyitozo irashobora kugabanwa mubwoko bwinshi, nk'imyitozo yihuta yihuta (imyitozo yo kugoreka, imyitozo yo mu matsinda, imyitozo iringaniye), imyitozo ya karbide ikomeye, imyitozo yerekana imyenge idakabije, imyitozo yimbitse, nibindi. Imyitozo, imyitozo ya trepanning hamwe nimyitozo isimburwa mumutwe, nibindi.
1. Gutunganya / gutunganya
1.1 Inzira
❶ Ukurikije umurambararo n'uburebure bwuzuye bwa drill bit yagenewe, urashobora guhitamo imashini ikata ibishishwa cyangwa gukoresha ibikoresho byo guca insinga mugutunganya uburebure.
❷ Kubirebire-burebure buringaniye bwo gukata, impande zombi zumurongo zirangiritse, zishobora kugerwaho kumurongo wintoki.
❸ Gutobora cyangwa gutobora isura yanyuma yumurongo wa alloy wabaye hasi, mugutegura gusya diameter yo hanze hamwe na shanki ya biti ya drill, ukurikije niba ibikoresho byo gusya bya silindrike ari inama yumugabo cyangwa inama yumugore.
❹ Ku mashini isya cyane ya silindrike, diameter yo hanze ya biti ya drill, igice cyimbere hamwe na diameter yo hanze ya shanki iratunganywa kugirango harebwe ibisabwa nkibishushanyo mbonera nka silindrike ya diameter yo hanze, kuzenguruka kuzenguruka, no kurangiza hejuru.
❺ Kugirango tunonosore imikorere yo gutunganya imashini isya CNC, mbere yuko umurongo wa alloy ushyirwa kumashini isya CNC, igice cyimyitozo gishobora gutoborwa, kurugero, inguni ya drill ni 140 °, kandi chamfer irashobora kuba hafi y'ubutaka kugeza kuri 142 °.
❻ Nyuma yo guhanagura akabari kavanze, yimurirwa mubikorwa byo gusya CNC, kandi buri gice cyimyitozo itunganyirizwa kumashini atanu ya CNC yo gusya.
❼ Niba ari ngombwa kunoza umwironge wa biti ya drill hamwe nuburyo bworoshye bwuruziga rwo hanze, birashobora kandi kuba hasi kandi bigasukurwa hamwe niziga ryubwoya hamwe na abrasives mbere cyangwa nyuma yintambwe ya gatanu. Byumvikane ko, muriki gihe, bito bito bigomba gutunganywa mu ntambwe nyinshi.
❽ Kubice byimyitozo yatunganijwe kandi yujuje ibyangombwa, bizashyirwaho ikimenyetso cya laser, kandi ibirimo birashobora kuba ikirango cya sosiyete LOGO nubunini bwimyitozo nandi makuru.
❾ Gupakira ibikoresho byerekanwe hanyuma ubyohereze mubikoresho byabigize umwuga byo gutwikira.
1. Niba umwironge wa biti ya drill yafunguwe, cyangwa umwironge uzunguruka cyangwa ugororotse, iyi ntambwe ikubiyemo no gutitira nabi kuruhande rwa peripheri; hanyuma utunganyirize guca kumurongo wimyitozo, harimo igice cyo gusubira inyuma cyimyitozo hamwe nu mfuruka yinyuma ya myitozo; hanyuma ukomeze Igice cyinyuma cyuruhande rwa periferique ya biti ya biti iratunganywa, kandi umubare munini wigitonyanga ni hasi kugirango umenye neza ko igice cya diametre yinyuma cyuruhande rwa periferique ya biti ya biti hamwe nubuso bwihuza bwurukuta rwakazi. ku kigero runaka.
2. Kugirango utunganyirize chamfer itari nziza ya drill tip edge, igabanijwemo CNC yo gusya imashini itunganya cyangwa gutunganya intoki, ibyo bikaba bitandukanye bitewe nibikorwa bitandukanye bya buri ruganda.
1.2 Gutunganya ibibazo
❶ Mugihe utunganya uruziga rwinyuma rwimyitozo kumashini isya ya silindrike, birakenewe ko twita niba igikoresho kitemewe no gukonjesha burundu amavuta mugihe cyo gutunganya, no gukomeza ingeso nziza yo gupima diameter yinyuma ya umwitozo.
❷ Mugihe utunganya imyitozo kumashini zisya CNC, gerageza gutandukanya gutunganya neza kandi neza mubyiciro bibiri mugihe utegura porogaramu, kugirango wirinde impanuka zishobora guterwa no gusya cyane, bizagira ingaruka kumurimo wa serivise.
❸ Koresha icyuma cyateguwe neza kugirango ukoreshe ibyuma kugirango wirinde kwangirika gukata guterwa no kugongana hagati yicyuma.
❹ Kubiziga bya diyama byahindutse umukara nyuma yo gusya, koresha ibuye ryamavuta kugirango ukarishe inkombe mugihe.
Icyitonderwa: Ukurikije ibikoresho byatunganijwe / ibikoresho / imiterere yakazi, tekinoroji yo gutunganya ntabwo ari imwe. Gahunda yavuzwe haruguru yerekana gusa igitekerezo cyumwanditsi kandi ni itumanaho rya tekiniki gusa.
2. Gucukura ibikoresho
2.1 Icyuma cyihuta
Ibyuma byihuta cyane (HSS) nicyuma cyigikoresho gifite ubukana bwinshi, kwihanganira kwambara cyane no kurwanya ubushyuhe bwinshi, bizwi kandi nkibyuma byihuta byuma byuma cyangwa ibyuma byimbere, bikunze kwitwa ibyuma byera.
Icyuma cyihuta cyane nicyuma cyo gukata gikaze kandi cyoroshye gukata kuruta ibisanzwe bisanzwe. Icyuma cyihuta cyane gifite ubukana, imbaraga nubushyuhe burenze ibyuma bya karubone, kandi umuvuduko wacyo wo hejuru urenze ibyuma bya karubone (ibyuma bya karuboni). Hariho byinshi, nuko yitwa ibyuma byihuta; na sima ya karbide ifite imikorere myiza kuruta ibyuma byihuta, kandi umuvuduko wo kugabanya ushobora kwiyongera inshuro 2-3.
Ibiranga: Ubukomezi butukura bwibyuma byihuta birashobora kugera kuri dogere 650. Icyuma cyihuta cyane gifite imbaraga nubukomere. Nyuma yo gukarishya, gukata birakaze kandi ubuziranenge burahagaze. Mubisanzwe bikoreshwa mugukora ibyuma bito kandi bigoye.
2.2 Carbide
Ibice byingenzi bigize sima ya carbide drill bits ni tungsten carbide na cobalt, bingana na 99% yibigize byose, naho 1% nibindi byuma, bityo byitwa karubide ya tungsten (karbide ya tungsten). Carbide ya Tungsten igizwe byibura nicyuma kimwe cya karbide Yacuzwe. Carbide ya Tungsten, karbide ya cobalt, niobium carbide, karbide ya titanium, na tantalum karbide nibintu bisanzwe bigize ibyuma bya tungsten. Ingano yintete yibigize karbide (cyangwa icyiciro) mubisanzwe iba hagati ya micron 0.2-10, kandi ibinyampeke bya karbide bifatanyirizwa hamwe hakoreshejwe icyuma. Ibyuma bifata ibyuma ni ibyuma byitsinda ryitsinda, bikunze gukoreshwa ni cobalt na nikel. Kubwibyo, hariho amavuta ya tungsten-cobalt, amavuta ya tungsten-nikel hamwe na tungsten-titanium-cobalt. Gucumura ibyuma bya tungsten ibyuma bitobora ni ugukanda ifu mumatike, hanyuma ukayashyushya ubushyuhe runaka (ubushyuhe bwa sinteri) mu itanura ryacumuye, ukabika mugihe runaka (gufata umwanya), hanyuma ukayikonjesha kubona ibikoresho bya tungsten ibikoresho hamwe nibisabwa.
Ibiranga:
Ubukomezi butukura bwa karbide ya sima irashobora kugera kuri dogere 800-1000.
Umuvuduko wo kugabanya karbide ya sima wikubye inshuro 4-7 ugereranije nicyuma cyihuta. Gukata neza.
Ingaruka ni imbaraga nke zo kunama, gukomera gukomeye, gukomera kwinshi, hamwe ningaruka nke hamwe no kurwanya kunyeganyega.
