1、 I 摘 要 单冲干粉压片机是通过凸轮(或偏心轮)连杆机构(类似冲床的工作原理)， 使上、下冲产生相对运动而压制药片。单冲式并不一定只有一副冲模工作， 也可以有两副或更多，但多副冲模同时冲压，由此引起机构的稳定性及可靠 性要求严格，结构复杂，不多采用。随着现代科技的发展，压片机涉及的行 业越来越广泛，高科技、高效率，低成本已成为现代压片机的一个重要的发 展趋势。 本次设计以小型单冲式压片机为例, 介绍了单冲式压片机的基本结构组 成、工作原理及工作过程, 阐述了国内外单冲式压片机的发展现状, 同时根 据其发展现状分析了目前单冲式压片机所存在的主要缺陷, 并指明了其发展 趋势，而且经过对压片机构造

2、和运动进行了分析与合成。使其能够稳定的运 行并完成连续自动化生产的要求。 关键词：压片机；单冲；连杆机构；片剂 II Abstract Single pressing machine is through the eccentric CAM (or similar) linkage (principle of work), punch, and ran down to the relative motion and suppress tablets. Single blunt type must not only a pair of stamping work, also can have t

3、wo or more, but the more pressing, stamping and vice arising from the organization of the stability and reliability of complex structure, strict, So it does not often used. With the development of modem science and technology，tablet pressing machine is used in more and more industries. High technolo

4、gy, high efficiency and low cost have become the most important trend of current tablet pressing machine. Taking the small single punch tablet press as an example, this paper introduced the basic structure, working principle and working process o f the single punch tablet press. It also introduced t

5、he development stat us of the single punch tablet press. In the meantime, this paper introduced the analysis of the major shortcomings of the current single punch tablet press and the proposition of the development direction according to the development status.Mean while ,In the organization of the

6、structure and movement is analyzed. It can make sure the operation and complete continuous automated production. Keywords：tablet machine; single punch; linkage; tablet III 目 录 摘 要 I Abstract II 第 1 章 绪 论 1 1.1 压片机的概况. 1 1.2 国内外的发展情况 2 1.2.1 国内压片机现状 . 2 1.2.2 国外压片机现状 . 4 1.3 本次设计的任务 6 第 2 章 压片机总体设计 7 2.1 设计题目分析. 7 2.1.1 给定数据 7 2.1.2 总功能分析 7 2.1.3 工作原理 8 2.2 机械运动方案及机构设计 9 2.2.1 拟订执行构件的运动形式 . 9 2.2.2 拟订运动循环图 . 10 2.2.3 确定主加压机构方案 11 2.2.4 评选机构方案 . 12 第 3 章 冲压机构与凸轮机构的设计 . 15 IV 3.1 铰链四杆机构. 15 3.2 连杆
