机械液压闸式剪板机的设计精选.doc

摘 要 在全球近年来工业高速的发展，在发展的这过程中剪板机起到了举足轻重的作用，比如在许多汽车公司和一些机械公司需求很大。在通过分析现状和实地考察的前提下，从机械剪板机和液压剪板机中选择了优势比较大的液压闸式剪板机作为设计对象，在设计中通过各种剪板机的运动原理、性能、实用性、功能、经济的对比体现出液压闸式剪板机的优点。液压闸式剪板机通过液压缸的往返运动实现上刀架的运动，使剪板机完成剪切的方式。通过了解液压闸式剪板机刀，完成了平面图设计、刀架的设计、挡料板的设计、剪切力计算、剪切厚度、剪切长度、刚度校核，最终设计出经济实用的剪板机。 关键词：液压闸式，剪板机，刀架，剪切长度，挡料板 全套图纸，加  ABSTRACT In the global industry high-speed development in recent years, in the process of the development of the shearing machine has played a pivotal role, such as in many car companies and some machinery company is a big demand. On the premise of through analyzing the status quo and on-the-spot investigation, from the mechanical shearing machine and hydraulic plate shears chose advantages bigger hydraulic brake type shearing machine as a design object, through all sorts of shearing machine movement principle in the design, performance, practicality, functionality, economic contrast reflects the advantages of hydraulic brake type shearing machine. Hydraulic brake type shearing machine by hydraulic cylinders movement on the movement of the head, make plate shears complete shear mode. By understanding the hydraulic brake type shearing machine knives, completed the plan design, the design of the tool post, retaining plate design, the thickness of the shear force calculation, shear, shear, the length, rigidity of the final design out of the economic and practical shearing machine. Key words: Hydraulic brake type, shearing machine, tool post, shearing length, baffle plate  目 录 摘 要……………………………………………………………………………………………Ⅰ ABSTRACT…………………………………………………………………………………Ⅱ 1 前言…………………………………………………………………………………………1 1.1 课题选择的背景和缘由 …………………………………………………………………1 1.2课题设计的目的和意义. …………………………………………………………………1 1.3闸式剪板机设计的主要内容和基本要求 ………………………………………………2 1.3.1剪板机的相关知识概述………………………………………………………………2 1.3.2各种剪板机市场现状分析……………………………………………………………3 1.3.3机械式和液压式剪板机的特性对比分析……………………………………………6 2 方案论证……………………………………………………………………………………7 2.1 本课题主要功能要求 ……………………………………………………………………7 2.2 课题可采用的设计方案 …………
