Cov hniav quenching ntau ntawm cov khoom siv cua sov ntau zaus

Cov kev pabcuam kev kho cua sov thiab kev ua haujlwm ntawm cov pob ntsia hlau: Cov ntsia hlau yog qhov tseem ceeb ntawm kev sib kis ntawm ntau yam cuab yeej siv tshuab. Nws yog ib qho kev sib kis thiab muab tso rau qhov chaw ua haujlwm uas hloov cov lus tsa suab mus rau hauv cov lus tsa suab lossis hloov cov kab lus tawm mus rau hauv cov lus teb. Muaj ob pawg tseem ceeb ntawm cov cuab yeej siv lub tshuab screws: trapezoidal screws thiab pob screws. Ntawm lawv, lub pob ntsia hlau muaj kev sib kis tau zoo, kev ua haujlwm rhiab, kev noj zaub mov zoo ib yam thiab ruaj khov, tsis muaj kev nkag ntawm qhov ceev, siab qhov chaw raug thiab rov ua haujlwm, thiab kev pabcuam ntev. Nws yog dav siv hauv CNC tshuab cuab yeej thiab machining chaw.

Lub pob ntsia hlau feem ntau raug khoov, torsion, qaug zog, thiab cuam tshuam thaum ua haujlwm, thiab tib lub sijhawm muaj kev sib txhuam ntawm cov zawv zawg thiab qhov sib hloov. Cov ntaub ntawv tseem ceeb ntawm kev puas tsuaj rau pob ntsia hlau yog hnav thiab qaug zog. Yog li ntawd, nws txoj kev ua tau zoo yog tias tag nrho yuav tsum muaj cov cuab yeej zoo txhua yam (uas yog, qee qhov kev sib xyaw ntawm lub zog thiab lub zog) thiab qhov siab ruaj khov, thiab cov khoom ua haujlwm cuam tshuam (kev sib tw, txoj kab uas hla) yuav tsum muaj siab hardness, siab zog. thiab txaus Lub abrasion kuj.

Quenching txheej txheem piav qhia ntawm pob ntsia hlau xov:

Ua ntej muab cov khoom ua haujlwm rau hauv inductor (coil), thaum muaj qee zaus ntawm kev hloov tam sim no dhau los ntawm inductor, ib qho chaw sib nqus sib nqus yuav raug tsim nyob ib puag ncig nws. Lub electromagnetic induction ntawm alternating magnetic teb tsim ib tug kaw induced tam sim no nyob rau hauv lub workpiece ─ eddy tam sim no. Kev faib tawm ntawm qhov induced tam sim no ntawm tus ntoo khaub lig-section ntawm lub workpiece yog heev unevenly, thiab tam sim no ceev ntawm qhov chaw ntawm lub workpiece yog siab heev thiab maj mam txo nyob rau hauv sab hauv. Qhov tshwm sim no hu ua cov nyhuv ntawm daim tawv nqaij. Lub zog hluav taws xob ntawm cov high-density tam sim no nyob rau saum npoo ntawm lub workpiece yog hloov dua siab tshiab rau hauv lub zog hluav taws xob, thiaj li hais tias qhov kub ntawm qhov saum npoo yog nce, uas yog, cov cua sov saum npoo yog pom tau tias. Qhov siab dua qhov zaus tam sim no, qhov sib txawv ntawm qhov tam sim no ntau dua qhov sib txawv ntawm qhov chaw thiab sab hauv ntawm lub workpiece, thiab lub thinner lub cua sov txheej. Tom qab qhov kub ntawm cov cua sov txheej tshaj qhov tseem ceeb ntawm qhov kub ntawm cov hlau, nws tau txias sai heev kom ua tiav qhov quenching thiab cov txheej txheem kho cua sov.
