卡箍冲压模具设计
摘要
本次设计主要设计了冲压模具中的落料模具和弯曲模具。经过老师的提示和指导,我首先分析制件的工艺性,根据工件的工艺尺寸,算出冲压力,选压力机,算出凸凹模的尺寸,选取模架,校核所选的零件能承受的力是否满足所要承受的冲压力,最后用CAD、ProE画图。本次设计是把一个钢板冲压成一个带缺口的圆筒,设计经过老师的多次指导,同学们和我的多次讨论,自己的多次修改,结合了大学期间所学的一切专业知识,最终设计出了比较理想的两套模具。冲裁模具就直接冲裁,弯曲模具根据材料的弯曲特性,算出弯曲前得半径,设计凸凹模,再根据弯曲原理,设计出了弯曲模具。这次设计让自己在大学所学的知识有所应用,让我对理论应该与实践相结合有进一步的理解了、也锻炼了自己提出了问题,分析问题和解决问题的能力。

Caliper stamping die design
ABSTRACT
This time, the main design of stamping die design of blanking die and bending die. After the teachers tips and guidance, I first of all analyses of parts of the process, according to the dimensions of the workpiece, calculated the stamping force, selected press, worked out of the punch and die size, select mode, check whether the selected parts can withstand the force of meet to withstand the impact pressure, finally using CAD, ProE drawing. This design is into a band gap of a steel cylinder, designed after repeated instructions to teacher, students and I discussed his modified several times, with all the expertise of the University during the ultimately designed two sets of mould is ideal. Blanking die just blanking, bending die under bending of material properties, worked out before bending radius, the design of punch and die, then according to the principle of bending, design of bending die. This design let himself in University knowledge application, let me integrating the theory and practice should be further understood, exercise their own questions have been raised, the ability to analyze and solve problems.
KEY WORDS: Stamping dies, band gap of cylinder,steel plate, the two sets of mould
