伴隨近幾年汽車(chē)輕量化開(kāi)展的進(jìn)度加快,越來(lái)越多的汽車(chē)制造企業(yè)開(kāi)始采用鋁合金板來(lái)作為汽車(chē)制造的主材料,這也得益于該材料的性能,符合企業(yè)需求,那么,企業(yè)對于鋁合金板材究竟有哪些性能方面的要求呢?鋁板生產(chǎn)廠(chǎng)家為您分析:
With the acceleration of the development of automobile lightweight in recent years, more and more automobile manufacturing enterprises begin to use aluminum alloy plate as the main material of automobile manufacturing, which also benefits from the excellent performance of the material and meets the needs of enterprises. So what are the performance requirements of enterprises for aluminum alloy plate? The aluminum plate manufacturer analyzes for you:
需要具備良好的成形性。板材的成形性是指在沖壓過(guò)程中其承受形狀變化的能力,成形性可以通過(guò)成形性實(shí)驗進(jìn)行評價(jià)。目前,鋼板的成形性已有大量實(shí)驗結果,但鋁合金板的成形性實(shí)驗結果完全可以滿(mǎn)足汽車(chē)在性能方面的需要。
First of all, good formability is required. The formability of sheet metal refers to its ability to withstand shape changes during the stamping process. The formability can be evaluated through formability experiments. At present, there are a lot of experimental results on the formability of steel plate, but the formability of aluminum alloy plate can completely meet the needs of automobile in terms of performance.
其次,要有一定的抗時(shí)效穩定性。鋁合金板在室溫存放時(shí)不發(fā)生時(shí)效的特性稱(chēng)之為抗時(shí)效穩定性,因為時(shí)效會(huì )使合金在拉伸變形時(shí)出現屈服點(diǎn)伸長(cháng),從而在沖壓時(shí)造成表面變形不均和起皺,影響沖壓件的外觀(guān),板材從生產(chǎn)出廠(chǎng)到零件沖壓時(shí)往往需要運輸和儲存一些時(shí)間,通常要求板材在室溫存放6個(gè)月而不發(fā)生時(shí)效。
Secondly, it is necessary to have certain anti-aging stability. The characteristic that aluminum alloy plates do not age when stored at room temperature is called aging resistance stability, because aging will cause the alloy to elongate its yield point during tensile deformation, resulting in uneven surface deformation and wrinkling during stamping, which will affect the appearance of stamping parts. The plates often need to be transported and stored for some time from the production to the stamping of parts. Generally, the plates are required to be stored at room temperature for 6 months without aging.
當然了,良好的烘烤硬化性也是很關(guān)鍵的,汽車(chē)沖壓件軋沖壓后經(jīng)油漆烘烤處理時(shí)也會(huì )產(chǎn)生時(shí)效,從而使其屈服強度上升的特性稱(chēng)之為烘烤硬化性,高的烘烤硬化性將會(huì )賦予零件高的抗凹痕性,由于目前大部分汽車(chē)企業(yè)的油漆烘烤工藝是針對鋼板設計的,而鋁合金的烘烤硬化性和鋼的明顯不同,因此,希望鋁合金板的烘烤硬化性好和鋼板的油漆工藝兼容,材料的烘烤硬化性可按相關(guān)標準進(jìn)行評定。
Of course, good baking hardenability is also very important. After rolling and stamping, automotive stamping parts will also have aging when they are painted and baked, so that their yield strength will rise. This characteristic is called baking hardenability. High baking hardenability will give parts high dent resistance. Because the current paint baking process of most automotive enterprises is designed for steel plates, and the baking hardenability of aluminum alloy is significantly different from that of steel, It is hoped that the baking hardenability of aluminum alloy plate is good and compatible with the painting process of steel plate, and the baking hardenability of material can be evaluated according to relevant standards.
