Cov nyhuv ntawm Hardness Tolerance Ntawm Hnav-Resistant Polyurethane Cov Khoom Ntawm Machining: Polyurethane Sheets Thiab Rods

Teeb meem tshwm sim thaum lub sij hawm machining thaum lub hardness kam rau ua ntau yam loj heev.

1. Tsis zoo deg (roughness, waviness, txiv kab ntxwv tev)

· Nyob rau hauv cov cheeb tsam uas muaj siab hardness, txiav kuj yog siab, thiab lub cuab tam nyhav "hla"; nyob rau hauv cov cheeb tsam uas tsis tshua muaj hardness, cov khoom yog yooj yim "torn" es tsis txiav.

· Qhov no ua rau cov cuab yeej tsis sib xws, waviness, lossis qhov tsis sib xws, ua rau nws nyuaj rau ua tiav qhov yuav tsum tau ua tiav.

2. Poob qhov tseeb qhov tseeb (tawm - ntawm - roundness, straightness sib txawv)

· Thaum tig sab nraud los yog lub qhov hauv, qhov sib txawv hardness ua rau tsis sib xws ntawm cov khoom ua haujlwm hauv clamping lossis txiav quab yuam.

· Tom qab lub fixture raug tso tawm, tsis sib xws elastic rov qab ua rau roundness yuam kev, taper, los yog chim -zoo li tus profiles (yog hais tias qhov kawg yog ib qho nyuaj thiab nruab nrab yog mos, qhov nruab nrab bulges; qhov opposite ua rau ib tug concave puab).

3. Chiping thiab ntug fragmentation

· Thaum lub zos hardness siab dhau lawm, cov khoom yuav nkig, thiab chipping los yog me me flakes yuav tshwm sim ntawm cov cuab yeej nkag / tawm, uas yuav ua rau scrapping ntawm workpiece nyob rau hauv mob hnyav.

4. Delamination thiab kua muag

· Thaum cov cheeb tsam hauv zos yog mos heev, cov khoom muaj zog heev thiab tsis zoo shear kuj.

· Tensile tearing, delamination, los yog dov-up burrs yuav tshwm sim ntawm milled npoo los yog laum tawm, tiv thaiv kev tsim ntawm ib tug huv contour.

5. Kev tsim hluav taws kub hnyav thaum lub sijhawm ua haujlwm, txawm tias kub kub / yaj

· Cov kev sib txhuam coefficient sib txawv heev ntawm qhov nyuaj thiab mos alternating, ua rau lub zos kub buildup ntawm lub cuab tam thiab workpiece.

· Tsawg- qhov chaw tawv tawv yuav ua rau mos, lo, daim ntawv filaments, lossis txawm tias hauv zos yaj thiab scorch; siab -qhov tawv tawv tej zaum yuav muaj oxidation ntawm qhov chaw thiab xim vim qhov kub thiab txias tsim los ntawm kev sib txhuam nyuaj.

6. Cov cuab yeej hnav tsis zoo (chipping, hnav tsis sib xws)

· Cov cheeb tsam nyuaj ua zoo li "cov khoom abrasive" ua rau cov cuab yeej siv nrawm nrawm, thaum cov chaw mos zoo li lo rau lub cuab yeej, tsim ua - nce npoo.

· Kev txiav ntug nthuav tawm tsis sib xws chipping lossis hauv zos hnav ntau dhau, ua rau lub neej luv luv.

7. Clamping deformation thiab springback ua rau seem

· Thaum clamped nrog peb - lub puab tsaig chuck, taw tes rau kev ntxhov siab nyob rau hauv cov cheeb tsam nyuaj yuav ua rau tawg, thaum cov chaw mos yuav compressed thiab dented.

· Tom qab machining thiab tso tawm, cov cheeb tsam mos rov qab thiab protrude thaum cov cheeb tsam nyuaj tseem tsis hloov, ua rau tawm hauv - ntawm - kam rau ua tiav qhov ntev (tshwj xeeb tshaj yog rau nyias - phab ntsa lossis lub nplhaib - zoo li qhov chaw).

8. Nyuaj kom ntseeg tau tias coaxiality lossis perpendicularity

· Tsis sib npaug ntawm qhov chaw siv qhov chaw ua rau lub hauv paus dav hlau tig los yog tig me ntsis hauv qab clamping siab.

· Qhov no ua rau cov qhov uas tsis yog perpendicular mus rau qhov kawg ntawm lub ntsej muag, los yog cov kauj ruam qhov uas tsis yog coaxial.
