1、 毕业设计(论文) 轭铁冲裁、弯曲成形工艺 及模具设计 学 院： 机械工程学院 专 业： 模具设计与制造 姓 名： 学 号： 指导教师： 摘 要 I 摘 要 本文主要介绍的是冲压、弯曲模具的设计，其工作原理是通过压力机带动 与制件形状类似的凸凹模冲压钢板，得到初步工件；再通过弯曲模将上一工序 的工件弯曲成规定角度。本文共包括二二章，对该组模具的设计过程进行了详细 说明。 该组模具是由两套模具（冲裁模、弯曲模）组。两套模具基本上都是由三 部分组成，一、定位装置，主要由定位板、定位销控制，用于板料的定位；二、 卸料装置，该部分通过弹性卸料板，打杆、打板组成，完成工件及废料的卸除； 三、成型部分，该

2、部分包括冲裁凸凹模、弯曲凸凹模，通过凸凹模、弯曲模的 闭合制成工件。 该型号的冲裁、弯曲模使用模具钢制造，卸料、定位装置可用 45 钢制造， 其他零件可直接从标准件中选取，这样可以降低成本，缩短模具的制造时间。 通过模具进行生产可以大大提高生产成本，降低零件的生产周期，提高生 产效率，因此，开发制造该类产品具有广阔的市场前景。 关键词：冲裁、弯曲凸凹模，定位装置，卸料装置。 ABSTRACT II ABSTRACT In this paper, the punching, bending mold design, working principle of their work is drive

Through the mold production can greatly enhance the production costs and lower parts of the production cycle, increase productivity, therefore, the development and fabrication of such products have broad market prospects.
