(1)模具的導(dǎo)向機(jī)構(gòu)精度。準(zhǔn)確和可靠的導(dǎo)向，對(duì)于減少模具工作零件的磨損，避免凸、凹模啃傷影響極大，尤其是無間隙和小間隙沖裁模、復(fù)合模和多工位級(jí)進(jìn)模則更為有效。為提高模具壽命，設(shè)計(jì)時(shí)必須根據(jù)工序性質(zhì)和零件精度等要求，正確選擇導(dǎo)向形式和確定導(dǎo)向機(jī)構(gòu)的精度。 (2)模具（凸、凹模）刃口幾何參數(shù)。凸、凹模的形狀、配合間隙和圓角半徑不僅對(duì)沖壓件成形有較大的影響，而且對(duì)于模具的磨損及壽命也影響很大。如模具的配合間隙直接影響沖裁件質(zhì)量和模具壽命。精度要求較高的，設(shè)計(jì)中就宜選較小的間隙值；反之則可適當(dāng)加大間隙，以提高模具壽命。</p><p

及無法得到良好精度的沖壓加工。有關(guān)沖頭之側(cè)壓對(duì)策有下列方法：(A).改變加工方向，(B).單側(cè)加工 (沖切、彎曲、引伸等) 之制品宜采兩排布列方式，(C).沖頭或凹模裝設(shè)側(cè)壓擋塊，切刃之側(cè)面設(shè)有導(dǎo)引部 (尤其是切斷及分?jǐn)嗉庸?。沖壓加工時(shí)主要作用件（沖頭、壓料板、凹模）之后方將承受面壓，當(dāng)沖壓力高于面壓力時(shí)宜采用背壓板 (特別是沖頭及凹模模套之背面) 背壓板之使用方式有局部使用與多方面使用兩種形式。汽車車身沖壓模具是沖制汽車車身上所有沖壓件的模具。</p><div style="width:100%;text-align: center;"><img

近年來，除了不斷有多種高韌性和高耐磨性冷作模具鋼、火焰淬火冷作模具鋼、粉末冶金冷作模具鋼推出外，國(guó)外在大中型沖壓模具上選用鑄鐵材料，是一個(gè)值得關(guān)注的發(fā)展趨勢(shì)。球墨鑄鐵具有良好的強(qiáng)韌性和耐磨性，焊接性能、可加工性、表面淬火性能也都較好，而且成本比合金鑄鐵低，因此在汽車沖壓模具中應(yīng)用較多。模具精細(xì)化制造，是對(duì)模具的開發(fā)過程和制造結(jié)果而言的，具體地表現(xiàn)為沖壓工藝和模具結(jié)構(gòu)設(shè)計(jì)的合理化、模具加工的高精度、模具產(chǎn)品的高可靠性和技術(shù)管理的嚴(yán)密性。模具精細(xì)化制造其實(shí)并不是一項(xiàng)單一的技術(shù)，而是設(shè)計(jì)、加工和管理技術(shù)的綜合反映。模具精細(xì)化制造的實(shí)現(xiàn)除了靠技術(shù)上精益求精，還要靠嚴(yán)密的管理來保障。模具的配合間隙直接影響沖裁件質(zhì)量和模具壽命。吉安模具作用有哪些</p><p

style="text-indent:25px">模具工作過程中，在循環(huán)應(yīng)力的長(zhǎng)期作用下，往往導(dǎo)致疲勞斷裂。其形式有小能量多次沖擊疲勞斷裂、拉伸疲勞斷裂接觸疲勞斷裂及彎曲疲勞斷裂。模具的疲勞斷裂性能主要取決于其強(qiáng)度、韌性、硬度、以及材料中夾雜物的含量。當(dāng)模具的工作溫度較高進(jìn)，會(huì)使硬度和強(qiáng)度下降，導(dǎo)致模具早期磨損或產(chǎn)生塑性變形而失效。因此，模具材料應(yīng)具有較高的抗回火穩(wěn)定性，以保證模具在工作溫度下，具有較高的硬度和強(qiáng)度。有些模具在工作過程中處于反復(fù)加熱和冷卻的狀態(tài)，使型腔表面受拉、壓力變應(yīng)力的作用，引起表面龜裂和剝落，增大摩擦力，阻礙塑性變形，降低了尺寸精度，從而導(dǎo)致模具失效。冷熱疲勞是熱作模具失效的主要形式之一，幫這類模具應(yīng)具有較高的耐冷熱疲勞性能。泉州模具批發(fā)市場(chǎng)</p><p
