Umurongo wo guhingura ububi
Ivyuma bishika nk’ibipande vy’umurongo w’inzira. P20 grade ku bipimo vy’ibikorwa bimenyerewe. Icemezo c’ibikoresho kigaragaza ubukomezi bugera kuri 28-32 HRC imbere-bukomeye buvuye ku rusyo. Nta bushuhe bukenewe imbere y’uko bukoreshwa n’imashini. Ku bikoresho vy’uburemere bwinshi vyitezwe ko bizogenda birenze inzinguzingu 500.000, iduka rihindukira rikaja ku H13 canke S136 stainless. Ivyo bikeneye gukomera inyuma yo gukoreshwa n’imashini zikomeye, ivyo bikaba vyongera indwi ku rutonde n’ibice 20-30% ku giciro.
Igikorwa kibanza co gukoresha imashini gica gitera igice c’ibarabara maze kigaca ibice vyo gushiramwo. Imyobo y'amabuye, aho amapine ari, ivyinjira vy'umurongo w'amazi. Ico gikorwa gikorwa ku mashine isanzwe yo gusesa. Nta kintu kidasanzwe. Iryo buye rero rikaja muri CNC kugira ngo rikoreshe ivyuho. Igishushanyo ca 3D kivuye ku mukiriya kijana inzira y’ibikoresho. Gutera ivyatsi bisiga 0.3-0.5mm ku bibanza vyose kugira ngo umuntu ashobore guheza. Kugerageza gukora cane hafi y’ivyo bishobora gutuma igikoresho gihungabana be n’ibimenyetso vy’ugusemerera bifata igihe kirekire kugira ngo biveho mu nyuma.
Iherezo ry'imashini rizana ibipimo vy'imyobo ku spec ya nyuma. Ivyiyumviro bigenda ±0.02mm ku bintu bihambaye nk’umufuko w’antene n’umurongo w’ugutandukanya. Igipande co hasi mu mufuko gitegerezwa kuba gisanzwe kiri hagati ya 0.01mm canke ibitandara vy’inlay RFID iyo umuntu yicayemwo. Insyo z’iherezo ry’umupira zifise uburebure bwa 1mm na 2mm zikora ahantu hagoramye. Radi ntoyi zija kuri EDM.
Gucapura kw’ama electrode bigenda bihuye n’ugucapura kw’ivyuma vy’imyobo. Graphite canke umuringa bivanye n’ivyo guheza umwobo ukeneye. Imashini za graphite zinyaruka kandi zifata ibintu vyiza cane. Umuringa uratuma ivyuma bimera neza cane ariko urashaza ningoga kandi ukaba ugura amahera menshi ku ntungamubiri imwe imwe. Ivyuma vyinshi vy’amafunguro bikoresha ama electrode ya graphite afise intambwe ya kabiri yo gusukura inyuma y’aho.
Ico kibanza ca EDM giturira ivyo CNC idashobora gushikako. Imfuruka z’imbere zisongoye. Ivyumba bikomeye vy’agahomerabunwa. Ivyerekeye ikimenyetso n’inkuta zihagaze. Ico gikoresho c’umuyagankuba kirarohama mu gikoresho mu gihe umuyagankuba usohoka ushobora gusenyura ibintu. Igihe co guturika kivana n’uburebure n’uburebure bw’ubutaka. Igipande c’ikimenyetso c’uburebure bwa 0.5mm gishobora gutwara amasaha 4. Iyo mashini ikora ata wuyicungera ijoro ryose kugira ngo ibone ibintu vyimbitse.
Gusukura bitandukanya igikoresho gikora n’ikindi ciza. EDM isiga igice gishasha ku bipande vy’icuma. Ico gipande kirakomeye kandi kiramenagurika. Gusukura birayikuraho maze bikazana uruhande ku mpera yategekanijwe. Ivyiyumviro vya SPI biha umuntu wese ikibanza kimwe. A-1 ni indorerwamo irangiza. B-1 ni umurongo mwiza cane ufise imirongo imwe imwe iboneka. C-1 yerekana ibimenyetso vy’ugutera amabuye bikeyi. Ivyuma vy'amafunguro akenshi bifise B-2 canke B-3. Guca ibibatsi cane bisigura igihe kinini co gusukura no kwambara ningoga mu gihe co gukora.
Ivyo bikoresho bishika inyuma yo gusukura iyo umukiriya ashaka ibintu bifise amabara canke bifise ibishushanyo. Ivyo gucapura bikoresha aside kugira ngo birye ivyuma mu buryo bugenzurwa. Ico gikoko kirapfukwa, hanyuma kikabikwa. Igitutu c’ibara ry’agahama gica 0.02-0.05mm ku bishushanyo bisanzwe. Laser texturing iriko iraronka ikibanza ku bishushanyo bikomeye ariko bigura vyinshi ku sentimetero kare.
Gucukura umuyoboro wo gukonjesha bishika kare mu gihe iyo bubiko ikiri yoroshe gukoresha. Ivyuma vy’imbunda vyari bifise imyobo igororotse biciye mu vyuma. Uburebure bw’umubiri akenshi ni 8-12mm. Ivyicaro n’uburebure bivana n’aho ubushuhe bwibanda mu gihe co kubumbabumba. Ivyo bimenyetso birapfungwa kandi bikageragezwa imbere y’uko bikoranywa kugira ngo bimenye ko ata n’imwe ivuye. Umurongo w’amazi uvuza imbere mu gitereko kiriko kiragenda uratuma haba umugese n’ubuhumane bushobora kwonona ibihimba vy’umubiri imisi myinshi imbere y’uko umuntu wese akurikirana ingorane.
Ikoraniro rizana hamwe igice c’imyobo, igice c’imbere, amasahani y’ugusohora, ibipimo vy’uburongozi, n’ibikoresho vyo gushiramwo. Ivyuma vy’ububiko biva kuri DME canke HASCO birazigama umwanya. Icobo n’umutima bigwa mu mifuko y’imbere y’-imashini. Gutunganya bivana n’ibipimo vy’uburongozi n’ibipimo vy’uburongozi. Ugumbara kuri ivyo bihimba vyerekana nk’umuco ku bihimba kubera ko ibice vy’ububiko bitagihura neza.
Igenzura rya mbere ry’ingingo ribera ku CMM. Guhuza imashini zipima zipima ibipimo bihambaye ku citegererezo ca 3D. Ikintu cose kiri hanze y’ukwihangana kirashirwako ibendera. Ivyo bimenyerewe ni imifuko miremire yahindutse mu gihe c’ugukora imashini be n’inkuta zitoyi zagendagenda mu gihe c’ugukora EDM. Gukosora bisigura gusubira ku kibanza ca CNC canke EDM. Rimwe na rimwe gukosora biranyaruka cane mu gusukura amaboko canke gusudira amabara no gusubira -mashini.
Ivyigwa vy'igerageza bitanga ibice vy'akarorero kugira umukiriya yemeze. Ico gikoresho gica kirungikwa mu kibanza co kubumbabumbamwo, kigashirwa mu mashini yo gucapura, hanyuma kigatera amajana makeyi. Ivyitegererezo bija muri QC kugira ngo bisuzumwe ingero n’igerageza rya RF. Ivyo guhindura bibera ku kibanza. Ingano y'irembo yoshobora gukenera gufungurwa nimba ibice vyerekana ibimenyetso vy'ugukekeranya. Igihe co gukonjesha coshobora gukenera kwagurwa iyo ibice bihindutse inyuma yo gusohoka. Ivyo bihinduka bifata umusi umwe canke ibiri. Igihe ivyerekanwa bimaze guca, igikoko kiraca kija mu guhingura.
Igitigiri c’amasasu gitangura kuva kuri zero kuri iyo nkuru. Igihe co gusanasana gishirwa ku rutonde bishingiye ku kwambara kwitezwe. Ico gipfukisho kizogaruka mu cumba c’ibikoresho amaherezo kugira ngo kivugururwe. Ivyumba vy'umurongo wo gutandukanya bisubira -butaka. Ivyuma vy’ejector vyambaye birasubirizwa. Gusukura bizana iherezo ry’imyobo risubira ku spec y’intango. Igikoresho co gukoresha neza -gikora inzinguzingu 300.000 gushika ku 500.000 imbere y’uko gisanurwa cane. Ibikoresho vyirengagijwe birabura vuba cane.
