摘要
 
 本课题来源于纵梁的实际生产过程。完成纵梁批量生产，并且要达到客户的要求。但是传统的生产方式很难做到，因此纵梁弯曲模的设计在此当中很有必要。论文介绍了模具行业的一些发展趋势和模具制造方法，并且提到了一些模具制造的新技术，同时也介绍了纵梁弯曲模的设计过程。首先对纵梁弯曲的工艺进行分析，再对几种模具结构方案进行比较分析后确定纵梁弯曲模的方案，然后进行设计计算和模具结构设计。该模具具有结构简单，操作方便的特点，最后介绍了模具制造加工方法和模具安装调试方法，提出了在调试过程中如何发现纵梁弯曲的缺陷，并介绍了减少或消除缺陷的方法。该模具应用到实际生产中，提高了生产效率，降低了劳动强度，给企业带来了技术效益和经济效益。

Abstract
  
 This topic originates from the carline actual production process. Completes is the carline volume production, and the request achieves the customer’s request. But the traditional production method is very difficult to achieve, therefore it’s very necessary to design the carline’s Curving mold .The thesis briefed the mold profession some development tendencies and the mold manufacture method, and mentioned some molds make the new technology, simultaneously also introduced the carline’s curving mold design process. First, it carries on the analysis to the carline curving craft, and carries on the comparative analysis after several kinds of molds structures plan to determine the carline’s curving mold plan, then carries on the design calculation and the mold structural design. This mold has the structure to be simple, ease of operation characteristic .Finally introduced the mold manufacture processing method and the mold install the debugging method, proposed how in the debugging process discovered the carline curving flaw, and introduced reduced or the elimination flaw method. This mold applies in the actual production, enhanced the production efficiency, reduced the labor intensity, has brought the technical benefit and the economic efficiency to the enterprise.

Keywords: The carline’s curving  Craft  Mold  Structural design
