4)酸洗:将冷却后的锻件进行酸洗,去除表面金属氧化皮,清理表面石墨,得到表面处理的铝合金筋板矩形锻件。(4) Pickling: pickling the cooled forgings to remove the metal oxide scale on the floor, clean the floor graphite, and acquire the rectangular forgings of aluminum alloy ribs with floor treatment.锻件冷却后,本发明优选还包括对冷却后的锻件进行酸洗,去除表面金属氧化皮,清理表面石墨,得到表面处理的铝合金筋板矩形锻件。本发明对所述预制坯和模具的加热方式没有特殊要求,采用本领域技术人员熟知的加热方式即可。本发明对所述酸洗的实施方式没有特殊要求,采用本领域技术人员熟知的酸洗方式即可。
图9为对比例2得到的矩形锻件示意图,从图中可以看出,锻件中间部分为带有连皮的孔,连皮的出现一方面说明对比例2锻件的投影面积大,模压力大,另一方面连皮的出现会增加切削工作量,增加劳动强度。本发明对所述润滑剂的用量没有特殊要求,能够起到防止锻件与模具相粘连的效果即可。在本发明中,所述润滑剂优选为石墨乳水溶液,所述石墨乳水溶液的质量百分浓度优选为15~20%。 2)锻造成形:将得到的铝合金预制坯放入箱式加热电阻炉中进行预热,加热到170℃时取出,并在坯件的表面均匀地喷涂石墨乳水溶液;将喷好石墨乳水溶液的坯件放入箱式加热电阻炉中,加热到410℃并保温2小时,最后将模具加热到430℃,将加热好的预制坯凸台向下放入下模的模膛内,在压力机作用下向上模施加2600吨的压力,上模下行速度为1.5mm/s,锻造温度为410℃,当坯件充满模膛后,压力机停止运行,成形完毕制得锻件;(2) Forging forming: put the obtained aluminum alloy preform into a field-type heating resistance furnace for preheating, take it out when heated to 170°C, and spray the graphite emulsion aqueous resolution evenly on the floor of the blank; spray the graphite emulsion The clean of the aqueous resolution is placed in a box-type heating resistance furnace, heated to 410 ° C and saved for 2 hours, and at last the mold is heated to 430 ° C, and the heated preform boss is positioned down into the cavity of the lower mold.
Oil & Gas Casting Components 。本发明对所述石墨乳水溶液的来源没有特殊要求,采用本领域技术人员熟知的市售商品即可。本发明对所述顶出装置的结构没有特殊限定,采用本领域技术人员熟知的顶出装置即可。本发明所述预热温度有利于润滑剂完整均匀的附着于预制坯上。 1)制坯:将厚80mm的铝合金原材料轧制板材进行机械加工,在坯料上表面四个边角部分加工出四个凸台,凸台的高度为4mm,凸台顶面为矩形平面,凸台两个侧面与底面垂直,与坯料侧面重合,另两个侧面以斜面过渡到坯料表面,斜面倾斜角度为164°,在坯料中间加工直径170mm的通孔,比凹模与通孔对应的约束台的直径大8mm,得到预制坯;(1) Billet making: The rolled sheet of aluminum alloy uncooked material with a thickness of 80mm is machined, and 4 bosses are machined on the four corners of the upper floor of the billet.
本发明所述预热的温度优选为160~180℃,进一步优选为170~180℃;本发明优选达到预热温度后立即将预制坯取出,在预热后的预制坯表面添加润滑剂。由以上实施例可知,本发明提供了一种铝合金筋板矩形锻件精密成形方法,在坯料中间设置通孔并采用反向加载的方式进行锻造,有利于减小成形时的模压力,同时又可避免出现折迭缺陷,降低切削工作量。下面结合实施例对本发明提供的铝合金筋板矩形锻件精密成形方法进行详细的说明,但是不能把它们理解为对本发明保护范围的限定。
