液压机逐日迅猛不断发展的体现

点击:

跟着液压机迅猛开展逐日开展壮大,相继建立了科研机构和专业出产厂家,从事液压技能研究和液压产品出产。其实液压机的组成结构并不杂乱,而现在液压机技能的开展正向着高效率,高精度,高功能方向迈进。液压元件向着体积小,重量轻,微型化和集成化方向开展,液压技能,沟通液压等新兴的液压技能正在开拓。又因为计算机的使用,更大大地推进了液压技能的开展,像液压体系的辅助设计,计算机仿真和优化,微机操控等作业,也都取得了明显效果。当时,液压技能在完成高压,高速,大功率,高效率,低噪音,经久耐用,高度集成化等各项要求方面都取得了严重的进展,在完善比例操控,司服操控,数字操控等技能上也有许多新成果。为了和最新技能的开展坚持同步,液压技能有必要不断开展,不断提高和改善元件和体系的功能,以满意日益改变的市场需求。这是液压技能的立异特征,液压技能的不断开展体现在如下一些比较重要的特征上:

With the rapid development of hydraulic press, the company has established scientific research institutions and professional manufacturers, engaged in hydraulic technology research and hydraulic products production. In fact, the structure of the hydraulic press is not messy, and now the hydraulic press skills are developing towards high efficiency, high precision and high function. Hydraulic components are developing in the direction of small size, light weight, miniaturization and integration, and new hydraulic skills, such as hydraulic skills and communication hydraulics, are being developed. And because of the use of computers, more greatly promote the development of hydraulic skills, such as hydraulic system aided design, computer simulation and optimization, microcomputer control operations, have also achieved remarkable results. At that time, hydraulic skills in high pressure, high speed, high power, high efficiency, low noise, durable, high integration requirements have made serious progress in improving the proportion of control, servo control, digital control skills also has many new achievements. In order to keep pace with the latest skills, hydraulic skills need to be continuously developed to continuously improve and improve the functions of components and systems to meet the changing market demands. This is the innovative feature of hydraulic skills, and the continuous development of hydraulic skills is reflected in some of the more important features:

1、进步元件功能,创制新元件,体积不断缩小。

为了能在尽可能小的空间里传递尽可能大功率,液压元件的结构不断地在向小型化开展。市场上呈现了一种新型的被称为“肌腱”的履行元件。它的形状像一根两端有接头的软管,把它接入体系使用时,它的径向和轴向都会发作弹性,轴向的弹性量可达其总长的15%--30%。在相同条件下,它的作用力是普通汽缸的10倍。这种元件抗污染,运动时不会生颤动,在有些场合还可用它的径向膨胀去夹持工件等,是一种极有应用远景的元件,而微型元件也得到开展,如活塞直径小到2.5mm的汽缸,10mm宽的气阀以及相关的辅佐元件已成为系列化产品。由于这些元件能在0.2---0.7Mpa压力下作业,所以可被方便地集成到标准的体系中。新小型阀,在流量相一起,它的体积仅是曩昔的7%。这些小,微型的元件已被应用于精密机械加工,电子工业,制药工业,食物加工和包装技能等场合。

2、高度的组合化,集成化和模块化。

冷挤压成型机液压体系由管式培装备经板式装备,箱式装备,集成块式装备开展到叠加式装备,插装式装备,使衔接的通道越来越短。也呈现了一些组合集成件,如把液压泵和压力阀作成一体,把压力阀插装在液压泵的壳体内,把液压缸和换向阀作成一体,只需接一条高压管与液压泵相连,一条回油管与油箱相连,就可以构成一个液压体系。这种组合件不光结构紧凑,作业可靠,并且简洁,也简略保护保养。

3、与微电子结合,走向智能化。

液压技能从本世纪70年代中期起就开端和微电子工业触摸,并彼此结合。在迄今30多年时间内,结合层次不断进步,由简略组装,涣散混合到总体组合,呈现了多种形式的独立产品如数字液压泵,数字阀,数字液压缸等,其间的高级形式已开展到把编了程的芯片和液压控制元件,液压履行元件或动力设备,检测反馈设备,数模变换设备,集成电路等汇成一体,这种汇在一起的联合体只需一收到微处理机或微型计算机处送来的信息,就能完成预先规定的使命。
