Tuam Tshoj Hollow Qhob Thaiv Moulds
Cov Core Pins ua qhov txawv
Lub hollow qhob thaiv yog txhais los ntawm nws lub qhov. Cov qhov no txo qhov hnyav, txhim kho rwb thaiv tsev, thiab txo cov nqi khoom. Tab sis lub qhov kuj tsim ib qho yooj yim tshaj plaws taw tes nyob rau hauv lub molding txheej txheem: cov tub ntxhais pins.
Tuam Tshoj cov tuam txhab lag luam tau ua qhov kev nce qib tseem ceeb hauv cov cuab yeej siv thev naus laus zis hauv kaum xyoo dhau los. Kev nkag siab txog cov kev nce qib no pab cov neeg yuav khoom sib txawv ntawm cov pwm uas yuav kav 80,000 lub voj voog thiab cov uas yuav poob ntawm 30,000.
UNIK tau raug tsim hollow qhob thaiv pwm hauv Quanzhou, Fujian txij li xyoo 2010, xa tawm mus rau 28 lub teb chaws. Nplooj ntawv no tsom ntsoov rau tus pin tseem ceeb- cov khoom uas cais cov hollow thaiv pwm los ntawm ib qho teeb meem.
Vim li cas Core Pins txiav txim siab Hollow Block Pwm Zoo
Core pins yog cov hlau rods uas tsim cov qhov hauv hollow blocks. Lawv txuas mus rau hauv lub pwm kab noj hniav los ntawm sab saum toj los yog sab, tshem cov pob zeb los tsim voids. Txhua lub voj voog, pob zeb ntws nyob ib ncig ntawm cov pins, compacts tawm tsam lawv, thiab tom qab ntawd tso tawm raws li qhov thaiv tau tawm.
Qhov kev rov ua dua tshiab no ua rau cov tseem ceeb pins rau peb hom kev ntxhov siab:
Kev puas tsuaj- Qhob aggregates swb tawm tsam tus pin nto thaum lub sij hawm txhua qhov sau thiab ejection voj voog.
Khoov- Tawm -qhov nruab nrab sau lossis tsis sib xws tuaj yeem thawb tus pins tawm ntawm kev sib dhos.
Kev qaug zog- Kev vibration cycles nws thiaj li ua rau microscopic tawg uas loj hlob dhau sijhawm.
Lub pwm tuaj yeem muaj cov kab noj hniav zoo meej thiab tseem ua tsis tau thaum ntxov yog tias cov pins tseem tsis tau zoo. Hloov pauv, cov pwm uas muaj siab - cov pins zoo tuaj yeem tsim cov blocks raug ntev tom qab cov kab noj hniav tau pib hnav.
Core Pin Specifications Qhov teeb meem
Thaum ntsuam xyuas hollow qhob thaiv pwm los ntawm cov neeg muag khoom hauv Suav teb, thov cov ntsiab lus hauv qab no:
Qib steel- Cov pins tseem ceeb yuav tsum muaj zog dua li cov kab noj hniav phab ntsa vim tias lawv muaj kev puas tsuaj ntau. Cov qib tau txais suav nrog Cr12MoV, 9CrSi, lossis siab - sib npaug ntawm cov hlau nrawm. Pins ua los ntawm cov txheej txheem steel yuav hnav sai heev.
Nto hardness- Core pins yuav tsum ua tiav HRC58-62 tom qab kev kho cua sov. Qee tus neeg muab khoom siv tsuas yog siv qhov tawv tawv; pins uas tsis hardened los ntawm kev pheej hmoo tawg nyob rau hauv rov khoov kev nyuaj siab.
Nto tiav- Pin nto yuav tsum polished rau Ra 0.8 lossis zoo dua. Cov pins ntxhib ua rau pob zeb los lo, tsim kom rub thaum ejection uas tuaj yeem rub tus pins tawm ntawm kev sib tw.
Taper- Core pins feem ntau muaj 1-2℃taper los pab tshem tawm. Ncaj pins tsis taper nce kev sib txhuam thiab hnav.
Lub hauv paus mounting- Pins yuav tsum tau ruaj ntseg mounted rau tus pin phaj. Loose pins hloov txoj haujlwm dhau sijhawm, ua cov blocks nrog cov phab ntsa tsis sib xws.
Common Core Pin teeb meem thiab kev daws teeb meem
| Teeb meem | Ua rau | Kev daws |
|---|---|---|
| Pins khoov los yog tawg | Tawm- nruab nrab pob zeb sau; compression siab heev | Kho cov khoom faib; txo compression; siv hardened pins |
| Cov phab ntsa tsis sib xws | Pins hloov nyob rau hauv xoob mounts | Hloov tus pin phaj; siv pinned lossis bolted mounting es tsis txhob nias - haum |
| Qhob sticks rau pins | Rough pin nto; tsis txaus taper | Polish pins rau Ra 0.8; nce taper mus rau 1-2 degrees |
| Pin nto pitting | Corrosion los ntawm pob zeb ntub dej | Siv stainless hlau pins los yog siv los tiv thaiv- txheej corrosion |
| Early pin hnav | Cov hlau mos; Kev kho cua sov tsis txaus | Qhia meej Cr12MoV nrog HRC60+ hardness |

Txheej txheem
Lub hollow thaiv pwm lub neej kev pab cuam feem ntau yog txwv los ntawm cov tub ntxhais pin hnav, tsis yog kab noj hniav hnav. Thaum pins hnav dhau qhov kev zam, tag nrho cov pwm yuav siv tsis tau txawm tias cov kab noj hniav tseem zoo. Qhov no ua rau tus pin zoo tsis sib npaug tseem ceeb rau tag nrho cov nqi.
Lub pwm nrog cov pins mos (HRC50-55) tuaj yeem tsim 30,000-40,000 blocks ua ntej pins hnav. Lub pwm nrog cov pins hardened zoo (HRC58-62) ua rau 80,000-100,000 blocks. Tus nqi sib txawv ntawm ob lub pwm yog feem ntau 15-25%. Qhov sib txawv ntau lawm yog 100-150% ntau blocks ib pwm.
Rau cov neeg yuav khoom, qhov kev suav no ncaj nraim: them me ntsis ntxiv rau qhov zoo pin hardening, lossis hloov tag nrho cov pwm ob zaug ntau zaus.
