Abstract

本实用新型提供了一种框架液压机的多点压边装置,在液压机的工作台内安装油缸,所述油缸安装在工作台的四边及中心;所述液压机工作台内的油缸只有中间的油缸与油箱的进油管连接。本装置的油缸分别分布在工作台的四个边及中心上,工作压力从该五点上给出,形成多点压边,其压力均匀,更适合压制大件的物体。

Description

框架液压机的多点压边装置
技术领域
本实用新型涉及一种框架液压机,具体涉及一种框架液压机的多点压边装置。
背景技术
目前市场上的液压机一般为一点压边,在大型覆盖件拉深成型过程中容易出现压边力不均的现象,进而影响拉深件质量。
实用新型内容
本实用新型提供了一种压力均匀的框架液压机的多点压边装置。
为了解决以上技术问题,本实用新型的一种框架液压机的压边装置,由滑块、工作台、油缸等组成,所述工作台内安装油缸,其创新点在于:所述油缸安装在工作台的四边及中心。
所述液压机工作台内的油缸只有中间的油缸与油箱的进油管连接。
以上结构的优点在于:所述液压机的油缸分别分布在工作台的四个边及中心上,工作压力从该五点上给出,形成多点压边,其压力均匀,更适合压制大件的物体。
附图说明
图1为本实用新型的结构示意图;
图2为图1所示本实用新型A-A向的结构示意图;
图3为本实用新型的油路示意图。
具体实施方式
如图1、2所示,在液压机工作台1的中心安装油缸a,在工作台四条边上分别安装油缸b、c、d、e。
如图3所示,油缸a的顶出腔和退回腔均通过进油管2连通油箱3。油缸b、c、d、e之间相互连通,也均连接到油箱3上。上述油缸a、b、c、d、e的油路上均连接有充液阀4和比例调节阀5。当油缸a进油、顶出时,油缸b、c、d、e形成负压,也随油缸a顶出,滑块向下滑行至合模。此时油缸a、b、c、d、e上的比例压力阀5均打开放油,使滑块继续向下,形成拉伸。在拉伸过程中,油缸a、b、c、d、e的压力通过比例压力阀5自动调节至压力一致,形成五点均等的压边力。

Claims (2)
