小型压力机的液压系统设计
摘要
作为现代机械设备实现传动与控制的重要技术手段,液压技术在国民经济各领域得到了广泛的应用。与其他传动控制技术相比,液压技术具有能量密度高﹑配置灵活方便﹑调速范围大﹑工作平稳且快速性好﹑易于控制并过载保护﹑易于实现自动化和机电液一体化整合﹑系统设计制造和使用维护方便等多种显著的技术优势,因而使其成为现代机械工程的基本技术构成和现代控制工程的基本技术要素。
液压压力机是压缩成型和压注成型的主要设备,适用于可塑性材料的压制工艺。如冲压、弯曲、翻边、薄板拉伸等。也可以从事校正、压装、砂轮成型、冷挤金属零件成型、塑料制品及粉末制品的压制成型。本文根据小型压力机的用途﹑特点和要求,利用液压传动的基本原理,拟定出合理的液压系统图,再经过必要的计算来确定液压系统的参数,然后按照这些参数来选用液压元件的规格和进行系统的结构设计。小型压力机的液压系统呈长方形布置,外形新颖美观,动力系统采用液压系统,结构简单、紧凑、动作灵敏可靠。该机并设有脚踏开关,可实现半自动工艺动作的循环。
Hydraulic system design of small presses
ABSTRACT
As one of the modern machinery equipment transmission and control important technical means, hydraulic technology in the field of national economy has been widely used. Compared with other transmission control technology, hydraulic technology has high energy density, flexible and convenient configuration, large speed range, rapid and smooth work ability, easy to be controlled and overload protection, easily realized automation and electromechanical integration ,system integration design ,easy maintenance in manufacturing operation and other significant advantages in technology , which make it e the basic technology of modern mechanical engineering and the basic technology of modern control engineering.
The hydraulic press and pressure machine is the main equipment for molding plastic injection and repressing material formation, such as stamping, bending, flanging, metal sheet drawing, etc. Also it can be engaged in the adjustment, the mounting indentation, the grinding wheel formation, the swaging metal parts formation, the plastic products and the powder products suppressed formation. This article according to the usage, characteristics and requirements of the purposes of the YB32-150 type hydraulic pressure press machine uses the basic principle of hydraulic transmission, draws up a reasonable hydraulic system and undergoes the necessary c
