钩形件斜楔式二次冲弯模设计

 【摘要】由于模具工业的重要性,模具成型工艺在各个工业部门得到了广泛的应用,使得模具行业的产值已经大大超过机床刀具工业的产值。这一情况充分说明在国民经济蓬勃发展的过程中,在各个工业发达国家对世界市场进行激烈的争夺中,越多越多地采用模具来进行生产,模具工业明显地成为技术经济和国力发展的关键.
 本次设计了一套弯曲模具。经过查阅^论文，首先要对零件进行工艺分析，经过工艺分析和对比，采用二次冲弯的弯曲工序，通过顶件力、卸料力和弯曲力等计算，确定压力机的型号。文章开始对工件弯曲成形工艺性进行了分析，紧接着介绍了复合模具设计：钩形件冲弯模。本次设计采用的凹模是活动凹模形式，方便更好的弯曲成形。文章对工件工艺性进行分析以后，开始了模具的设计过程，在毛坯的尺寸确定以后，从而确定工件的工艺方案。紧接着开始本文的重点设计部分——工件的弯曲工艺计算和模具总体设计。这两部分重点介绍了模具尺寸的确定、工艺力计算、压力机的选择以及弯曲模具结构的设计、各种标准件的选用以及模具材料的选用等等。文章的最后还介绍了模具的制造以及对本次设计作了相应的总结。

Hook-shaped wedge two punching bending die design
[Abstract]Due to die industrial of importance, die forming technology in all industrial sector are has widely of application, makes die industry of output has greatly over machine tool industrial of output. this a situation full description in national economy flourish of process in the, in all industrial developed on world market for fierce of compete for in the, more to used die to for production, die industrial clear to became technology economic and power development of key..
 This design has a curved mold. Through access to information, firstly to process your parts analysis, after a process of analysis and comparison, punching bending and bending process for the second time, through the top, unloading and bending strength calculation, determine the type of press. Article on bending forming technology for the analysis of artifacts, then introduced the compound mold design: punching bending die for hook-shaped parts. The design matrix is an active matrix form, easy to better bending. Article on artifacts of process analysis, start the mold design process, in stock size determines the future, so as to determine the process for the job. Immediately begin to focus on design section of this article-the calculation of bending technology and die design for the job. Highlighted in this two-part mold, process of determining size of calculation, press Select and the bending die structure design, selection of standard parts and molds materials selection, and so on. Last article also introduced mould manufacturing, as well as the design was appropriate summary
