Abstract

本发明提供了一种四柱式液压机,包括立柱、与立柱相连的上横梁、下横梁和活动横梁、活动横梁下方的上砧和下砧,还包括工作缸、回程缸、与工作缸相连的工作柱塞、与回程缸相连的回程柱塞;所述的立柱是以27SiMn为原料,经过亚温淬火和高温回火处理制成。本发明的四柱式液压机,由于带有亚温淬火和高温回火处理的立柱,因此具有高强度耐腐蚀的性能。

Description

一种四柱式液压机
技术领域
本发明涉及一种四柱式液压机,属于机床技术领域。
背景技术
液压机是一种利用液体静压力来加工金属、塑料、橡胶、木材、粉末等制品的机械。它常用于压制工艺和压制成形工艺,如:锻压、冲压、冷挤、校直、弯曲、翻边、薄板拉深、粉末冶金、压装等等。
它的原理是利用帕斯卡定律制成的利用液体压强传动的机械,种类很多。当然,用途也根据需要是多种多样的。如按传递压强的液体种类来分,有油压机和水压机两大类。
水压机产生的总压力较大,常用于锻造和冲压。锻造水压机又分为模锻水压机和自由锻水压机两种。模锻水压机要用模具,而自由锻水压机不用模具。我国制造的第一台万吨水压机就是自由锻造水压机。
立柱是液压机上的主要部件,立柱的作用不但要支撑上梁与油缸,承受工作拉力,还要对活动横梁起导向作用。
由于液压机的立柱使用频繁,易损伤,影响了液压机的使用。
发明内容
本发明的目的是克服现有技术的不足,提供一种四柱式液压机。
本发明的四柱式液压机,包括立柱、与立柱相连的上横梁、下横梁和活动横梁、活动横梁下方的上砧和下砧,还包括工作缸、回程缸、与工作缸相连的工作柱塞、与回程缸相连的回程柱塞;
所述的立柱是以27SiMn为原料,经过亚温淬火和高温回火处理制成。
优选地,
所述的亚温淬火和高温回火处理过程如下:将27SiMn试样加热到830℃淬火,再加热到560℃回火。
本发明的四柱式液压机,由于带有亚温淬火和高温回火处理的立柱,因此具有高强度耐腐蚀的性能。
具体实施方式
