圆框冲压工艺分析和侧向双冲切舌模具设计

Stamping Technology Analysis of Loop Frame and Die Design of Side-double Stamping and Bending

分析了筒灯圆框的冲压工艺 ,通过工艺计算和利用车制简易模具进行实际试作验证工艺方案结果、对主要工作机构进行可行性理论分析和实际验算 ;论证侧向冲切舌凸、凹模均采用斜楔滑块机构的可行性和论证以1 33mm的圆周范围内两组侧冲切舌凸模斜楔滑块机构在 1 80°和 1 2 0°之间实现切换生产两种不同产品的可行性 ,最终确定加工方案的过程 ;并介绍了第三工序侧向双冲切舌模具结构形式。

The stamping technology of loop frame of columnar light was analyzed. The feasibility analyses of main work machine and practical checking computations were carried out by technology calculation and using simple die to validate the technology result. The feasibkility of using wedge sliding mechanism in side double stamping & bending die and the feacibility of producing two kinds of different parts by changing two groups of wedge sliding mechanism either 180° or 120° at  133mm range are demonstrated. At the end the process is chosen. Die structure, wedge sliding mechanism and working principle of side double stamping & bending die of the third process are also introduced.
