Hluav taws xob hlau tooj dag Stamping Parts xav tau kev tswj kom meej ntawm tooj liab-zinc theem ciam teb, tensile lub zog tsis, thiab kev tuag clearances mus cuag hluav taws xob conductivity theem siab tshaj los yog sib npaug mus rau 28% IACS thaum tuav tswj yield zog tshaj 350 MPa. As global OEMs demand tighter dimensional tolerances down to ± 0.005 mm for high-density power distribution units and EV relay architectures, material selection and multi-stage stamping parameters dictate long-term operational reliability under IEC 60947 compliance frameworks.
Metallurgical Properties thiab Alloy xaiv rau Cold Stamped Brass Component Precision Stamping
Brass alloys, feem ntau binary tooj liab-zinc systems xws li C2680 (Cartridge Brass) thiab C2600, muaj qhov tshwj xeeb txias- ua haujlwm tau zoo thiab lim- cov yam ntxwv hardening. Thaum siv hauv kev tuag stamping, cov ntaub ntawv no ua rau cov yas deformation hnyav yam tsis muaj micro- tawg raws li cov ciam teb.
Kev sib koom ua ke ntawm cov tshuab xovxwm siab dhau los tso cai rau Xiamen Apollo Electric Co., Ltd. kom tswj hwm cov micro-hardness profiles, tiv thaiv qhov tsis sib xws ntawm qhov qis dua - qib tooj liab alloys. Hauv qab no yog kev sib piv ntawm cov qib tooj dag uas siv hauv kev tsim hluav taws xob:
| Alloy Designation | Nominal Composition | Hluav taws xob conductivity (% IACS) | Tensile zog (MPa) | Daim Ntawv Thov Hluav Taws Xob |
|---|---|---|---|---|
| C26000 Cartridge tooj dag | Cu 70% / Zn 30% | 28% - 32% | 340 - 450 | Relay terminals, ntsaws pins, lub caij nplooj ntoos hlav hu |
| C26800 (Yaj Brass) | Cu 65% / Zn 35% | 26% - 30% | 370 - 480 | Grounding straps, fuse clips, busbar connectors |
| C51900 (Phosphor Bronze) | Cu-Sn-P | 15% - 20% | 450 - 600 | Siab -kev nyuaj siab tiv tauj springs, me me keyboards |
Progressive Die Stamping Mechanics thiab Kev Tiv Thaiv Tsis Zoo rau Multi-Bend Brass Stamping Terminal
Kev ua haujlwm siab -ceev, ntau- chaw nres tsheb nce qib stamping rau Hluav Taws Xob Sib Txuas Cov Khoom Siv Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob xav tau kev tswj xyuas nruj tshaj qhov kev tshem tawm, feem ntau khaws cia ntawm 6% - 8% ntawm cov khoom tuab. Tsis txaus clearance accelerates punch hnav thiab induces burr tsim, thaum ntau clearance ua rau cov ntaub ntawv rollover thiab dimensional distortion.
Cov txheej txheem tseem ceeb
- Punch Velocity:Tswj tau ntawm 120 - 180 strokes/min kom txo cov thermal distortion thaum lub sij hawm tho thiab blanking. Lubrication Viscosity: Synthetic chlorinated -dawb kos duab roj siv los ntawm automated micro-dispensers kom tshem tawm galling ntawm complex formed flanges.
- Residual Stress Relief:Tshaj tawm -stamping qis- kub annealing tua nyob rau hauv cov tswj kev tiv thaiv huab cua tiv thaiv kev ntxhov siab corrosion cracking (SCC) raws li ASTM B858 tus qauv.
Nrog rau peb cov engineers hluav taws xob niaj hnub no
Corrosion Resistance thiab Ib puag ncig ua raws li Brass Electrical Cheebtsam
Cov khoom siv hluav taws xob xa mus rau hauv kev lag luam automation, ntse ntsuas, thiab lub tshuab hluav taws xob hauv tsheb tau niaj hnub raug rau huab cua phem, av noo, thiab ntsev tsuag. Brass inherently tsim kev tiv thaiv patina nplua nuj nyob rau hauv zinc oxide, passivating lub hauv paus substrate tiv thaiv oxidation txhoj puab heev.
Txhawm rau ua kom tau raws li cov lus qhia ib puag ncig thoob ntiaj teb, txhua tus tsim khoom Stamping Riveting Hluav Taws Xob Brass Xovxwm Ua raws nraim li RoHS thiab REACH txoj cai. Optional electroplated tiav-xws li ci tin (Sn 3-5μm), matte tin, los yog xim nickel underplating- yog siv los ntawm automated reel-to-reel plating kab kom lav tsis muaj kev sib cuag (tsawg dua los yog sib npaug li 5 mΩ) hla dhau 1 lub voj voog kev ua haujlwm.
Ua haujlwm raws li IATF 16949 thiab ISO 9001 cov txheej txheem tswj kev ua haujlwm zoo, Xiamen Apollo ntiav cov txheej txheem nruj ntau-tier soj ntsuam raws tu qauv. Dimensional verification siv siab- daws teeb meem kho qhov muag profile projectors thiab automated 2D / 3D coordinate Measuring machines (CMM) nrog sub-micron raug. Tsis tas li ntawd, kev ntsuam xyuas ntsev tsuag (ASTM B117) yog ib txwm ua los xyuas kom meej tias plated Brass Hlau Stampings tiv taus qhov tsawg kawg nkaus ntawm 96 - 240 teev ntawm nruab nrab ntsev tsuag yam tsis muaj hlau oxidation.
