Description

剪板机的液压系统
技术领域
本发明涉及一种剪板机的液压系统，属于机械设备领域。
背景技术
剪板机（英文名称：plateshears；guillotineshear）是用一个刀片相对另一刀片作往复直线运动剪切板材的机器。是借于运动的上刀片和固定的下刀片，采用合理的刀片间隙，对各种厚度的金属板材施加剪切力，使板材按所需要的尺寸断裂分离。剪板机属于锻压机械中的一种，主要作用就是金属加工行业。产品广泛适用于航空、轻工、冶金、化工、建筑、船舶、汽车、电力、电器、装潢等行业提供所需的专用机械和成套设备。
液压剪板机采用液压传动，使机器工作时平稳，噪声小，安全可靠，可以进行单次连续剪切，剪板厚度也较机械传动的厚，但是液压系统是利用液体作为中间介质来传递动力的，剪切力大时，油压也相应的高，对液压元件的精度、强度要求也高，制造成本也相应的较高，而且液压系统不可避免的存在，泄露问题，会造成污染，油温的变化会引起油液粘度变化，影响液压传动工作的平稳性，所以适应环境能力小。
发明内容
本发明的目的是克服现有技术的不足之处，提供一种剪板机的液压系统。
本发明的剪板机的液压系统，包括一号油箱、与一号油箱相连的粗过滤器、与粗过滤器相连的液压泵、与液压泵相连的溢流阀和调速阀、与调速阀相连的换向阀、与换向阀相连的封闭工作缸油路、通过封闭工作缸油路串联连接的两个油缸、与两个油缸同时相连的滑块，所述的溢流阀上连有二号油箱。
所述的换向阀为手动三位四通换向阀。
本发明的剪板机的液压系统设计独特，具有传动效率高、结构简单、可靠性高及易集成等特点。通过对剪板机液压系统的改进，提高了钢板剪切后的表面质量，剪切厚钢板时无肉眼可见的凹痕和变形，剪切精度也相应提高。
