三辊卷板机的设计

作 者 伟 人 指导教师 宋诚生

摘要：卷板机是一种将金属板材弯卷成筒体、锥体、曲面体或其他形体的通用成型设备。本设计旨在设计出用于卷制最大厚度为10mm、最大宽度为2000mm钢板的卷板机。本文首先简单介绍了卷板机的分类、工作原理及在我国的发展情况。结合任务书要求，通过对常用机构类型的论证，选择了本课题的对称式三辊卷板机。由分析整个卷板运动，将其分为主运动和辅运动。论证确定了主运动和辅运动的传动系统方案后，经过计算工作机构的工作功率及运动参数，选择电动机的型号。再对传动系统中各传动装置分别进行类型选择、材料及热处理选择、设计计算和校核。设计和校核工作机构的材料和尺寸后，对轴、轴承、联轴器和键进行设计计算，最后简述了机架的设计。 关键词：三辊卷板机 参数化设计 校核

The Design of The Three Roller Coiling Machine

Abstract：The bending machine is a common molding equipment which could bend plate into a cylinder, cone, curved body or other body .This design is aimed to design the bending machine rolling the maximum thickness of 10mm, maximum width of 2000mm plate .This article first briefly describes the classification of the bending machine, working principle and development in China. Through the demonstration of the common types of institutions and the task book , having chosen this three roller coiling machine. By the analysis of the entire coiling movement, it could be divided into the main and the auxiliary movement. After determining the drive system program of the main and the auxiliary movement , then calculating the power of working bodies and motion parameters, reaching the model of motor .And select the type of transmission system , materials and heat treatment , design calculations and check. Design and check the materials and size, shaft, bearings, couplings and key design calculations, the final rack design.

Key words：The three roller coiling machine Parameter design Check
