一种可移动式板材冲压机结构设计论文_学位论文.doc

摘 要 冲压机广泛用在大批量生产中。板材自动冲压机主要包括多工位冲压机和下传动自动冲压机。在冷锻中，自动冲压机用于紧固件例如螺栓螺母和钉子等。冲压成型是一种金属塑性加工方法，因冲压件具有重量轻，厚度薄，刚性好和质量稳定的特点，所以冲压设备被广泛使用，其中钣金件的百分之就是靠冲压成型。高速压力机是目前提高生产率重点发展的机型，在我国，高速压力机正在迅速兴起，实现大吨位高速度多工位自动化成型加工，其主体为机械式，充分利用机械结构简单的特点。依据高速压力机的工作特点，研究了高速压力机的惯性力降低及其平衡的途径，明确指出在高速压力机上不宜采用气缸平衡装置。在惯性力平衡方面也进行了较为系统的研究，采用多种方法进行优化。 本次设计的冲压机主要是用来对板材进行冲孔加工，同时根据其冲压机的工作和结构特点，对其C型结构也就是单臂结构方面进行受力分析，并在原有尺寸的基础上进行优化和校核。同时由于冲压机在工作过程中板材是不断进给的，因此也要设计出合理的板材夹装机构，同时设计的底座也应方便冲压机的整体移动，进而方便其板材的加工。 关键词：冲压机，液压系统，C型结构框架，板材装夹机构。 ABSTRACT Punching machine widely used in mass production.Sheet metal stamping machines include automatic multi-station punching machine automatic punching machine and the next drive. In cold forging,the automatic stamping machine for fasteners such as nuts, bolts and nails, etc. Stamping is a metal plastic processing methods, because of stamping parts for light weight, thin, rigid,and the quality and stability characteristics, it is widely used in stamping equipment.Percent of which is by sheet metal stamping. High-speed press is the focus on the development of models to improve productivity.High-speed press is on the rise in China,High-speed punching machine to achieve large-tonnage molding multi-station automation,the main body is machine,it take full advantage of the characteristics of a simple machanical structure.According to the working characteristics of high speed press.The inertia of the high-speed presses and the balance is reduced by means, clear that should not be used in high-speed presses cylinder balancing device. Balance the inertial force also conducted a more systematic study, using a variety of methods to optimize. The design of the stamping machine is used for sheet metal processing for punching, meanwhile according to its press work and structural features.The structure of its C-arm structure that is the force analysis.And on the basis of the original size optimization and verification. At the same time the press sheet in the course of the work is con
