FAQ:
Q1: Dab tsi yog pneumatic lub tog raj kheej piston pas nrig?
A: Cov pas nrig piston yog ib qho tseem ceeb thiab tseem ceeb ntawm txhua lub hydraulic lossis pneumatic lub tog raj kheej.Lub piston pas nrig feem ntau yog qhov tseeb machined ntev ntawm cov tawv chrome plated txias tiav steel bar uas xa cov quab yuam tsim los ntawm lub piston mus rau lub tshuab tivthaiv ua haujlwm.
Q2: Lub hauv paus ntsiab lus ntawm pneumatic lub tog raj kheej piston pas nrig yog dab tsi?
A: Lub tog raj kheej pneumatic piston nyob rau hauv lub tog raj kheej bears lub thrust los yog rub quab yuam generated los ntawm huab cua siab, thiab ncaj qha ua rau lub pneumatic lub tog raj kheej piston pas nrig txuas nrog lub piston, thiab ces lub pneumatic lub tog raj kheej piston pas nrig txuas nrog lub load workpiece kom txav. rov qab los.
Q3: Dab tsi yog cov khoom siv raw ntawm koj lub tog raj kheej pneumatic piston pas nrig
A: Feem ntau, lub tog raj kheej pneumatic piston pas nrig ntawm lub tog raj kheej pneumatic yuav xaiv 45 # hlau raws li cov khoom siv raw.Yog tias lub tog raj kheej tsim tau yuav tsum tau siv rau hauv ib puag ncig tshwj xeeb, 304 stainless hlau kuj tuaj yeem siv
Q4: Vim li cas thiaj xaiv 45 # steel li raw khoom
A: 45 # steel yog cov khoom siv zoo carbon steel nrog tsawg hardness thiab yooj yim txiav.Tom qab quenching, nws nto hardness tuaj yeem ncav cuag 45-52HRC.Thiab nws tseem tuaj yeem muaj kev ua haujlwm zoo dua thiab muaj zog dua, toughness thiab lwm yam khoom siv kho tshuab, yog li nws yog ib qho ntawm cov khoom siv feem ntau siv rau cov ncej.
Q5: Dab tsi yog cov txheej txheem machining ntawm koj lub tog raj kheej pneumatic piston pas nrig?
A: Txhawm rau kom tau txais kev ua haujlwm ruaj khov zoo, phau ntawv ncaj qha ntawm tus pas nrig piston tsis raug tso cai tom qab lub tshuab pib.Yog li ntawd, cov txheej txheem straightening yuav tsum tau ua ua ntej machining.Vim yog qhov tsis zoo ntawm cov khoom ua haujlwm, kev sib tsoo thiab kev ua haujlwm zoo yuav tsum tau nqa tawm thaum lub sijhawm machining txheej txheem los txhim kho qhov tseeb ntawm machining.Hom kev ua haujlwm ntawm piston pas nrig yog reciprocating linear motion.Txhawm rau txhim kho lub neej kev pabcuam ntawm tus pas nrig piston, qhov saum npoo yuav tsum yog chrome-plated los txhim kho nws qhov tawv tawv thiab hnav tsis kam.Tom qab chrome plating, polishing kev kho mob yuav tsum tau ua kom tau zoo dua nto roughness, txo kev sib txhuam, thiab txhim kho kev sib khi.Txij li cov txheej txheem polishing yuav luag tsis cuam tshuam rau sab nraud ntawm lub piston pas nrig, lub workpiece yuav tsum tau ua kom tiav qhov siab dua qhov roughness ua ntej chrome plating.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ntxiv cov txheej txheem sib tsoo ua ntej txheej txheem chrome plating (kev sib tsoo zoo kuj tuaj yeem txhim kho qhov adhesion ntawm chromium. ).Raws li cov kev soj ntsuam saum toj no, cov txheej txheem tsim nyog ntau dua rau cov pas nrig piston yog: straightening-rough turning-fine turning-fine grinding-chrome plating-polishing.
Q6: Dab tsi yog qhov polishing ntawm pneumatic lub tog raj kheej piston pas nrig
A: Thaum lub sij hawm tig, qhov chaw nruab nrab uas ua lub luag haujlwm ntawm qhov chaw yuav qhia tau qee qhov kev hnav.Txhawm rau kom ntseeg tau cov ntsiab lus sib koom ua ke ntawm cov qauv ntsuas, lub qhov nruab nrab yuav tsum tau muab txiav ua ntej sib tsoo kom ntseeg tau tias kev ua haujlwm zoo.Thaum sib tsoo, kev sib tsoo yuav tsum tau nqa tawm ntawm lub voj voog sab nraud nyob ze ntawm qhov kawg ua ntej, thiab kev sib tsoo ntawm tus pas nrig piston tuaj yeem nqa tawm tsuas yog thaum qhov kev sib tsoo ua tau raws li qhov yuav tsum tau ua.Ntxiv nrog rau kev txhim kho qhov tseeb qhov tseeb, cov txheej txheem sib tsoo zoo kuj yuav tsum tau txais qhov siab dua qhov roughness ntawm lub tshuab ua kom zoo dua qub los txhim kho kev sib raug zoo ntawm chromium ions thaum lub sij hawm electroplating txheej txheem.Txhawm rau kom ntseeg tau tias lub thickness ntawm chromium plating txheej ntawm lub piston pas nrig kawg yog ib yam, lub nto roughness tom qab kev sib tsoo zoo yuav tsum nyob ze rau ntawm qhov chaw roughness tom qab chromium plating thiab polishing.Yog hais tias qhov roughness ntawm lub piston pas nrig yuav tsum siab, xws li Ra <0.2 μm, nws yuav tsum tau finely av.Ntxiv super zoo sib tsoo los yog polishing txheej txheem tom qab sib tsoo.
