Diad pegley na ungol na assembly workshop ed Daiyue Machinery Company, say test run na sprocket shaft assembly et abayag lan ag-amta. Sayan manunan kabiangan, ya tatawagen ya "puso" na scraper conveyor, et mabetbet ya walay pirmin problema to: say itatagey na larak manlapud saray seal kayari na impan-assemble. Sayan pirmin problema so nagmaliw ya bottleneck, ya mangaamper ed inkaepektibo na produksyon tan amaatagey ed gastos.
Say Kodigo na Inobasyon ed "Operating Table"
"Say problema et walad 'ag nanengneng'." Say Technical Supervisor Li Chenguang so akayurong ed abay na ginawa lamet ya sprocket shaft assembly, ya insindag toy flashlight ed seal groove. "Say tradisyonal ya panagtipon et mandedependi ed 'liknaan' na master pian napindot so selyo. Say daiset a pressure et agmakapaelet ed satan, bangbalet say sobran pressure et nayarin maneral ed rubber seal. Anggapoy eksakton 'puersa'."
Saray process personnel na R&D center tan say technical backbone na workshop so maples ya nanggawa na task force pian paulit-ulit ya "diagnoseen" so manunan sengegan na sprocket shaft oil leakage.
"Ag ka manpokus ed balon kagawaan; say ebat et walad bunton na saray basura!" Say balikas na beteranon fitter a si Master Zhao diad miting na task force et sakey a panangiparungtal. Diad miting na grupo, inmarap ira ed sakey a suyok na talyer: sakey a daan a motor ya kulang so pakayari to balet ta walay aderal ya motor shaft to, pigaran seksion na daiset lan naupot ya drive chain, tan pigaran ag-inusar ya 16mm-makapal ya atagey-mabiskeg ya steel plates-sarayan bengatla, ya akamarka ya "biglan na-scrap," et mangiyoopresi na balo iran posibilidad. Saray teknisyan ed R&D center so nandrowing na inmunan drowing na desinyo, ya inusar da so daan ya motor bilang power core, chain drive pian naseguro so stable ya power output, tan sakey a hydraulic system pian nadampot so eksakton pressure control. Saray steel plates et inwelding ed sakey a malet ya akapeket a frame pian naseguro ya say shaft assembly et mansiansian "ag-onkikiwas" legan na pangi-install na press.
Dakel so inkadunong ya inlaktip ed pangipaakseb ed sayan solusyon. Say daan ya motor et dinmalan ed dynamic balancing tan bearing replacement, ya amabaleg na speed stability ya anggad ±2 r/min. Insan inyan so voltage stabilizer parad output na kuryente. Saray scrap chain et pinuter tan sinubok so inka-malet da, ya saray link labat so natilak ya kulang ed 0.1 mm so inka-wear da. Sarayan link et inpetek panamegley na saray espisyal ya kagawaan pian naseguro so transmission error ya kulang odino mipara ed 0.05 mm. Saray steel plates et in-welding ya inusar so "segmented symmetrical welding" ya proseso pian napaliisan so deformation na frame lapud welding stress. Say unor a panagsukimat so angipatnag na flatness error ya 0.03 mm labat parad interon tooling, ya angipaalagey na solidon "reference surface" parad eksakton operasyon. Say sankaimportantian ya hydraulic control system et walaan na makabayon digital pressure valve, ya mangi-lock ed press-fitting force control accuracy ed ±5 N. I-set labat na saray trabahador iray parametro, tan say sistema et automatikon makasumpal ed interon proseso na "pre-pressing, pressure-maintaining, tan pressure{17}living{17}living". Sayan "sprocket shaft assembly precision press-fitting tool," ya walay dagup ya pinansyal ya kulang ed 8,000 yuan, et nayarin ompatnag ya anggapoy kana, balet ta walay komplikadon core na millimeter-level control.
Manlapud "Pangilukas na Bulag a Kahon" anggad "Anggapoy Tagas"
"Say pangiyan na saray selyo et mamapawis ed saray palad ko." Si Yang Shuai, sakey a manag-assemble ya walaan na 20 taon ya eksperiensya, et nanonotan to ni so inmunan impangusar to na balon kagawaan: Say shaft assembly et malet ya akapeket ed kagawaan. Pinindot to so start button, tan say hydraulic gauge needle et tuloytuloy ya inmatagey ed 350N. Diad sakey a "click," say seal et eksakton akayurong. Legan na test run, sikatoy ginagala ton manalagar na duaran oras pian naseguro ton mansiansian amagaan so tapew na shaft-say sankaunaan ya "zero leakage" test run to ed loob na anem bulan. Say oil leakage rate et abawasan manlapud 23% ya anggad zero, kanian ag-akasumpal so "zero rework." Say panaon na panagtipon na sakey a sprocket shaft et abawasan manlapud 120 minutos ya anggad 78 minutos, ya amabaleg na 35% ya inkaepektibo. Say konsumo na lubricant ed binulan et abawasan manlapud 180 litro ya anggad 65 litro, kanian makatipid na masulok ya 120,000 yuan ed tinaon. Say karakel na masakbay a pakaderal na bearing lapud leakage et naekal la, ya mamaawang ed average ya bilay na kagawaan na 1.5 taon. Say mas baleg ya pananguman et walad inobasyon na modelo na produksyon. Saray teknikal ya babeng ya akadepende ed "panag-awit na marundunong a managgaway bengatla" nensaman et aderal la. Say estandardisadon operasyon na balon kagawaan so amamatikey ed panaon na panagpasal parad saray balon empleyado manlapud 3 bulan ya anggad 1 bulan, a talagan akarealsa ed "teknikal a panangiyalis tan sigpot a partisipasyon na amin ya empleyado."
Natan, no onloob ka ed Daiyue Machinery Company, nanengneng mo so "trial run tooling" ya gawad daan iran motor tan scrap chain ya siansia nin mankikimey. Saya so aliwan sakey labat a pananguman ed saray teknikal a kairapan, noagta sakey met a malinew ya alimbawa na pangiter na kompanya ed "manbilay a maong anggaman manbilay a matipid."
