Madhiri anogadzirwa sei? Ndeapi matambudziko achasangana mukudhirowa? Nezve chibooreso nezvinhu zvayo? Unoitei kana chibooreso chako chikatadza?
Sechishandiso chinowanzo shandiswa mukugadzira gomba, mabhiti ekudhirowa anoshandiswa zvakanyanya mukugadzira michina, kunyanya kugadzira makomba muzvikamu zvakaita semidziyo yekutonhodza, machubhu emidziyo yekugadzira magetsi, uye majenareta eutsi. Chikumbiro chakanyanya kuwanda uye chakakosha. Nhasi, Muzvinafundo weMechanical Engineering akawana iyi drill bit collection yemunhu wese ari pa WeChat platform. Zvese zvaunoda zviri pano!
Drilling Features
Madhiri anowanzo ane maviri makuru ekucheka micheto. Panguva yekugadzira, chibooreso chinocheka paunenge uchitenderera. Iyo rake angle yechibhorani inowedzera kubva pakati peakisi kusvika kumucheto wekunze. Iko kukurumidza kucheka kwechibhorani kunowedzera apo inoswedera pedyo nedenderedzwa rekunze, uye kukurumidza kwekucheka kunoderera kune pakati. Iko kumhanya kwekucheka kwenzvimbo yekutenderedza bhiti i zero. Iyo chisel mupendero weiyo drill bit inowanikwa padyo neaxis yenzvimbo yekutenderera, iyo chisel mupendero ine yakakura yekubatsira rake angle, isina chip nzvimbo, uye kucheka kumhanya kwakaderera, izvo zvinogadzira yakakura axial kuramba. Kana iyo chisel edge yakadzika kuti iite A kana kuti C muDIN1414, uye chidimbu chekucheka chiri pedyo nechepakati axis ine yakanaka rake angle, kushorwa kwekucheka kunogona kuderedzwa uye kushanda kwekucheka kunogona kuvandudzwa zvakanyanya.
Zvinoenderana neakasiyana maumbirwo echishandiso, zvigadzirwa, zvimiro, mabasa, nezvimwe, zvibooreso zvinogona kukamurwa kuita mhando dzakawanda, senge-high-speed simbi drills (twist drills, group drills, flat drills), solid carbide drills, indexable shallow gole drills, zvibooreso zvakadzika gomba, etc. Drills, trepanning drills and replaceable head drills, etc.
1. Maitiro / kugadzirisa
1.1 Maitiro
❶ Zvinoenderana nedhayamita uye hurefu hwakazara hwechidhirowa chakagadzirwa, unogona kusarudza alloy bar yekucheka muchina kana kushandisa waya yekucheka michina yeyakagadziriswa-kureba kugadzirisa.
❷ Kune yakatemwa-kureba yakachekwa bhaa, iyo miviri migumo yebhawa yakapfava-yakapera, iyo inogona kuwanikwa pane manual tool grinder.
❸ Chamfering kana kuboora kumagumo kwealloy bar yakagayiwa, kugadzirira kukuya dhayamita rekunze neshank yechibhorani, zvichienderana nekuti cylindrical grinding fixture ndeyechirume here kana kuti chikadzi.
❹ Pamushini wekukuya we-cylindrical wepamusoro, iyo dhayamita yekunze yechibooreso, chikamu chakakomba uye dhayamita rekunze reshank zvinogadziriswa kuti ive nechokwadi chekugadzira zvinodiwa senge yekunze dhayamita cylindricity, denderedzwa runout, uye kupera kwepamusoro.
❺ Kuti uvandudze mashandiro ekugadzirisa pamushini wekukuya weCNC, iyo alloy bar isati yaiswa pamushini wekukuya weCNC, chikamu chekuyeresa chinogona kukwizwa, semuenzaniso, iyo yekudhirowa yekona i140 °, uye chamfer inogona yakadzika kusvika ku142 °.
❻ Mushure mekunge chamfered alloy bar yacheneswa, inoendeswa kune CNC yekukuya muchina, uye chikamu chega chega chedhiri chinogadziriswa pane mashanu-axis CNC yekukuya muchina.
❼ Kana zvakakosha kuvandudza nyere yechibhorani uye kutsvedzerera kwedenderedzwa rekunze, inogona zvakare kukuyiwa nekukwenenzverwa nemavhiri emvere dzemakwai nemaabrasive pamberi kana mushure menhanho yechishanu. Ehe, mune iyi kesi, iyo drill bit inoda kugadziriswa mune mamwe matanho.
❽ Pamabhiti ekudhirowa akagadziridzwa uye akakodzera, anozoiswa chiratidzo chelaser, uye zvirimo zvinogona kunge zviri brand yekambani LOGO uye saizi yedrill uye rumwe ruzivo.
❾ Rongedza madhiri ekubooresa akanyorwa uye woatumira kune inyanzvi yekugadzira maturusi kambani yekupfekedza.
1. Kana nyere yechibhorani ichivhurwa, kana kuti spiral kana yakatwasuka nyere, danho iri rinosanganisirawo negative chamfering yemupendero weperipheral; wobva wagadzirisa chikamu chekucheka chechidimbu chekuchera, kusanganisira chikamu chekudzokera shure kwechibhorani chekuchera uye kona yekuseri kwechibhorani; wobva waenderera mberi Chikamu chekumashure chemupendero weiyo drill bit inogadziriswa, uye imwe huwandu hwekudonhedza pasi kuti ive nechokwadi chekuti dhayamita rekunze chikamu cheperipheral kumucheto kwechibooreso uye kutarisana pamusoro peworkpiece gomba madziro zvinodzorwa. mune chimwe chikamu.
2. Kugadziriswa kwechamfer yakaipa ye drill tip edge, yakakamurwa kuva CNC grinding machine processing kana manual processing, iyo yakasiyana nekuda kwemaitiro akasiyana efekitari imwe neimwe.
1.2 Kugadzirisa nyaya
❶ Paunenge uchigadzira chikamu chekunze chedenderedzwa pamushini wekukuya wecylindrical, zvinodikanwa kuti utarise kuti chigadziriso chacho hachina basa here uye kuti unyatso kutonhorera iyo alloy bar panguva yekugadzirisa, uye kuchengetedza tsika yakanaka yekuyera dhayamita rekunze. chibooreso tip.
❷ Paunenge uchigadzira madhiraini pamashini ekukuya eCNC, edza kupatsanura rough uye yakanaka kugadzirisa kuita matanho maviri paunenge uchigadzira, kuitira kuti udzivise kutsemuka kwemafuta kunokonzerwa nekunyanya kugaya, izvo zvinokanganisa hupenyu hwesevhisi yechishandiso.
❸ Shandisa tireyi yakagadzirwa zvakanaka yekubata kwemapanga kuti usakuvadze kumucheto kwekucheka kunokonzerwa nekudhumhana pakati pemapanga.
❹ Pagumbo redhaimani rave dema mushure mekukuya, shandisa dombo remafuta kurodza mupendero nenguva.
Ongorora: Zvinoenderana neyakagadziriswa zvinhu / midziyo / mamiriro ekushanda, tekinoroji yekugadzira haina kufanana. Kurongeka kwemaitiro kuri pamusoro kunongomiririra maonero emunyori uye ndeyekutaurirana kwehunyanzvi chete.
2. Drill zvinhu
2.1 High speed simbi
High-speed simbi (HSS) isimbi yemudziyo ine kuoma kwepamusoro, kukwirira kupfeka kusagadzikana uye kupisa kwakanyanya, inozivikanwawo seyepamusoro-speed tool simbi kana simbi yepamberi, inowanzozivikanwa sesimbi chena.
High-speed steel cutter imhando yekucheka yakasimba uye iri nyore kucheka pane vanochekawo zvavo. Simbi inomhanya-mhanya ine kusimba kuri nani, kusimba uye kupisa kupisa kupfuura kabhoni mudziyo simbi, uye kumhanya kwayo kwekucheka kwakakwira kupfuura kabhoni mudziyo simbi (iron-carbon alloy). Kune akawanda, saka inonzi simbi inomhanya-mhanya; uye cemented carbide ine mashandiro ari nani pane simbi yakakwira, uye kumhanya kwekucheka kunogona kuwedzerwa ne2-3 nguva.
Zvimiro: Kuoma kwakatsvuka kwesimbi yakakwirira-kumhanya kunogona kusvika ku650 degrees. Simbi yepamusoro-soro ine simba rakanaka uye kuoma. Mushure mekurodza, iyo yekucheka inopinza uye hutano hwakagadzikana. Anowanzo shandiswa kugadzira mapanga madiki uye akaoma kunzwisisa.
2.2 Carbide
Zvinhu zvikuru zvecemented carbide drill bits ndeye tungsten carbide uye cobalt, iyo inotora 99% yezvikamu zvose, uye 1% ndeimwe simbi, saka inonzi tungsten carbide (tungsten carbide). Tungsten carbide inoumbwa neinenge imwe simbi carbide Sintered composite zvinhu. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, uye tantalum carbide zvinhu zvakajairika zvetungsten simbi. Ukuru hwezviyo hwechikamu checarbide (kana chikamu) chinowanzova pakati pe 0.2-10 microns, uye zviyo zvecarbide zvinobatwa pamwechete uchishandisa simbi binder. Binder masimbi anowanzo simbi dzeboka resimbi, anowanzo shandiswa ari cobalt uye nickel. Nokudaro, kune tungsten-cobalt alloys, tungsten-nickel alloys uye tungsten-titanium-cobalt alloys. Iyo sintering molding ye tungsten simbi drill bit material ndeye kudzvanya hupfu mubillet, wobva waipisa kune imwe tembiricha (sintering tembiricha) muchoto chinopisa, chengeta kwenguva yakati (kubata nguva), wozoitonhodza pasi. kuti uwane tungsten simbi zvinhu nezvinhu zvinodiwa.
Features:
Kuoma kwakatsvuka kwecemented carbide kunogona kusvika 800-1000 degrees.
Iyo yekucheka kumhanya kwesimende carbide ndeye 4-7 nguva yakakwirira kupfuura iyo yesimbi inomhanya. Kunyatsocheka kwepamusoro.
Izvo zvisingabatsiri isimba rekukotama rakaderera, kusasimba kwesimba, kusimba kwepamusoro, uye kushomeka kwemaitiro uye kusada kuzunguzika.
