冷軋板，也稱作冷軋鋼板、冷軋薄板、冷板。包括不銹鋼板、彈簧鋼板、硅鋼片、鍍鋅板、鍍錫板、鍍鋁板等。冷軋板主要用于零件的沖壓加工，而冷軋板的力學(xué)性能十分重要，它直接關(guān)系到板材的沖壓性能。冷軋板是以不同的熱處理狀態(tài)分級的，不同硬度的材料，用于不同的加工方法。國家標(biāo)準(zhǔn)GB/T13237-1991《優(yōu)質(zhì)碳素結(jié)構(gòu)鋼冷軋薄鋼板和鋼帶》將冷軋薄板大致分為三級，P級用于普通沖壓，S級用于深度沖壓，Z級用于**深度沖壓。中國冶金標(biāo)準(zhǔn)YB/T5059-1993《低碳鋼冷軋鋼帶》將冷軋板帶按硬度分為五級，即：TR（特軟）、R（軟）、BR（半軟）、DY（低硬）和Y（冷硬）。其實(shí)通過一定的冷軋變形程度和冷軋后熱處理程度的適當(dāng)配合，可以在更***的范圍內(nèi)滿足用戶關(guān)于材料力學(xué)性能方面的要求。冷軋板根據(jù)用戶加工上的要求還可以分成更多的級別。例如：日本工業(yè)標(biāo)準(zhǔn)JISG3141-1996《冷軋?zhí)妓劁撲摪搴弯搸А返姆诸惓譃橐话阌茫╯pcc）、沖壓用(spcd)和深沖壓用（spce）三類外，還細(xì)分為退火、標(biāo)準(zhǔn)調(diào)質(zhì)、1/8硬、1/4硬、1/2硬、全硬等級別。在冷軋板力學(xué)性能的檢測方面，一些標(biāo)準(zhǔn)只規(guī)定了拉伸試驗(yàn)，另一些標(biāo)準(zhǔn)除拉伸試驗(yàn)外還規(guī)定了硬度試驗(yàn)。中國標(biāo)準(zhǔn)GB/T13237-1991就只規(guī)定了冷軋板的拉伸試驗(yàn)。多壓頭硬度機(jī)批量定制HRB：是采用100kg載荷和直徑，求得的硬度，用于硬度較低的材料（如退火鋼、鑄鐵等）。</p><div

硬度是一個(gè)專業(yè)的物理術(shù)語，材料局部抵抗硬物壓入其表面的能力稱為硬度。由于規(guī)定了不同的測試方法，所以有不同的硬度標(biāo)準(zhǔn)。各種硬度標(biāo)準(zhǔn)的力學(xué)含義不同，相互不能直接換算，但可通過試驗(yàn)加以對比。彈簧鋼砍粗鐵小意思硬度一般分為三種：①劃痕硬度。主要用于比較不同礦物的軟硬程度，方法是選一根一端硬一端軟的棒，將被測材料沿棒劃過，根據(jù)出現(xiàn)劃痕的位置確定被測材料的軟硬。定性地說，硬物體劃出的劃痕長，軟物體劃出的劃痕短。②壓入硬度。主要用于金屬材料，方法是用一定的載荷將規(guī)定的壓頭壓入被測材料，以材料表面局部塑性變形的大小比較被測材料的軟硬。由于壓頭、載荷以及載荷持續(xù)時(shí)間的不同，壓入硬度有多種，主要是布氏硬度、洛氏硬度、維氏硬度和顯微硬度等幾種。③回跳硬度。主要用于金屬材料，方法是使一特制的小錘從一定高度自由下落沖擊被測材料的試樣，并以試樣在沖擊過程中儲(chǔ)存（繼而釋放）應(yīng)變能的多少（通過小錘的回跳高度測定）確定材料的硬度。凌空削發(fā)不是神話在刀劍硬度的測試上，我們通常采用的是洛氏硬度測試中的HRC標(biāo)尺，通常用于測試淬火鋼、回火鋼、調(diào)質(zhì)鋼和部分不銹鋼。這是金屬加工行業(yè)應(yīng)用**多的硬度試驗(yàn)方法。HRC適用范圍HRC20－67。自動(dòng)打硬度硬度機(jī)技術(shù)參數(shù)</p><p>
