1. Taw qhia
Bolts, ceev, studsthiab kev lag luam fasteners feem ntau yog tsim los ntawm ob txoj hauv kev tsim thev naus laus zis: lub taub hau txias (txias forging) thiab kub forging. Cov txheej txheem kub ncaj qha txiav txim siab cov khoom siv kho tshuab kev ua haujlwm, qhov ntev ntev, tus nqi tsim khoom thiab cov xwm txheej siv tau. Phau ntawv qhia no rhuav tshem cov ntsiab lus sib txawv los pab cov engineers thiab cov neeg yuav khoom xaiv cov txheej txheem tsim khoom tsim nyog rau lawv cov phiaj xwm fastener.
2. Core txhais
Txias taub hau
Lub taub hau txias txheej txheem steel hlau rods nyob rau hauv chav tsev kub, siv high -ceev txias taub hau tshuab rau xuas nrig ntaus, extrude thiab tsim ntsia liaj qhov rooj hau, txiv ntseej blanks tsis muaj cua sov raw cov ntaub ntawv. Raw khoom: Smooth hlau kauj (10B21, 4.8 / 8.8 qib carbon steel, stainless hlau xaim).
Kub Forging
Kub forging heats steel tuav mus rau 800-1200℃recrystallization kub ua ntej, ces nias lub siab - kub billet nrog forging tuag los ua loj - loj, siab - lub zog fastener blanks. Cov khoom siv raw: Cov khoom siv hlau puag ncig (45 #, 40Cr, 4340 alloy steel).

| Khoom siv ntau yam | Tsawg / nruab nrab carbon steel, stainless hlau mos hlau | Nruab nrab / siab alloy steel, siab zog tempered steel tuav |
4. Qhov zoo thiab qhov tsis zoo
Cold Heading Pros
-Kev ua haujlwm zoo tshaj plaws: Cov hlau tsis muaj hlau tsis zoo txhim kho kev qaug zog tiv thaiv, zoo tagnrho rau tsheb fasteners (10B21 8.8 qib bolts).
-High precision: Uniform qhov ntev, zoo ib yam xov suab, tsawg dua ncej- ua.
-High automation: Kev tsim khoom loj txo tus nqi zog, ruaj khov lub sij hawm xa tuaj.
-Neeg huv si: Me me oxidation, zinc plating/Ruspert txheej adheres tusyees.
Cold Heading Cons
-Kev txwv loj: Tsis tuaj yeem ua cov ntsia hlau saum toj M24 vim cov khoom siv tonnage txwv.
-Cov khoom siv nyuaj: Cov hlau tsis muaj zog tsis tuaj yeem ua kom txias tsis muaj tawg.
Kub Forging Pros
-Unlimited size range: Ua super- cov studs loj, thauj tog rau nkoj bolts, siab nkoj bolts.
-High alloy compatibility: Ua haujlwm nrog 40Cr, A193 B7, duplex stainless hlau rau siab -kub siv kev lag luam.
-High forming force at high temp: Complex special -puab forgings can be shapes easy.
Kub Forging Cons
-Qhov tsis zoo: Cov nplai oxide tuab yuav tsum tau siv tshuab ua haujlwm thib ob.
-Kev qaug zog qis dua: Cov cua sov ua rau sab hauv cov hlau nplej ntws.
- Tus nqi siab dua: Kev siv hluav taws xob rau cua sov, kev tsim khoom qeeb qeeb, kev ua tiav ntxiv.

6. FAQ
Q1: Puas tuaj yeem kub - forged bolts ncav cuag 12.9 lub zog qib?
A: Yog, tab sis kub forging tsuas yog ua rau blanks. Tom qab kub sib sau, quenching & tempering kev kho cua sov yuav tsum tau mus txog qib 10.9/12.9. Lub taub hau txias 10B21 tuaj yeem ncaj qha mus rau qib 8.8 tom qab kev kho cua sov nrog kev ua haujlwm zoo dua.
Q2: Vim li cas cov khoom txias taub hau pheej yig dua rau cov qauv bolts?
A: Lub taub hau txias ua haujlwm siab tsis siv neeg siab - cov kab nrawm yam tsis muaj hluav taws xob hluav taws xob, tsawg dua cov kauj ruam ua haujlwm thib ob, cov zis ntau dua ib teev, uas txiav nqi tsev rau cov xaj loj.
