板料弯边机及动力箱设计 摘要 风阀是中央空调的组成部分。现在随着人民生活的需求量日益增大，使得风阀的使用量越来越大。风阀体板料大都是由薄壁板料加工而成，为了增加板料刚度需要进行折弯处理。本弯边机采用辊压成形对板料进行折弯处理。 板料在塑性弯曲时，由于中性层会发生内移，使得板材受拉伸的区域扩大，受压缩的区域减少，从而使板材的平均长度增加，在分析板材滚弯变形时的应力应变的基础上，运用弹塑性理论对板材的中性层移动、厚度减薄及长度增加进行了分析计算。 本设计的任务是完成一台板料弯边机的总体设计和部件设计，侧重点在动力箱的设计。在熟悉板料弯曲拉伸理论的基础上，设计出板料折弯机的工作原理，计算出相关参数，并确定部件及零件的型号、尺寸和动力参数。绘制弯边机联系尺寸图、动力箱的部装图及箱体零件图，并对主要零部件进行相关的校核计算。最后通过UG软件对动力箱进行三维设计,达到了三维实体造型的目的. 板带材产品薄而宽的断面决定了板带材产品在生产和应用上有其特有的优势条件。本设备具有结构相对紧凑、性能可靠、生产成本相对便宜、工作效率高等特点。 关键词　 风阀体；板料；弯边机；动力箱 The design of power box for wind valve and sheet metal bending Abstract Wind valve is an integral part of the central air-conditioning.Now with the lives of the people growing demand Valve allows the use of more and more.Valve body sheets are made ofthin-walled sheet metal which need bending processing in order to increase the stiffness of sheet.The machine is used roller roll forming of sheet metal to bend side to deal with. The design task is to complete a sheet metal bending mill design which focuse on the design of the power box. On the basis of in a familiar with stretch of sheet metal bending theory design of sheet metal bending mill working principle calculate inertia and related mechanical parameters and to identify parts and components model and size power and other parameters. Drawing size chart power box assembly and the main parts of work chart and main components of the associated check calculation.Finally through the power box on UG software for three-dimensional design reach the purposes of a three-dimensional solid modeling . Product thin plate strip wide cross-section of the board decided to strip products in the production and application has its unique advantages. The device has a relatively compact structure reliable performance the cost of production is relatively cheap high efficiency.
