摘要
针对镁合金常温下塑性较差导致自冲铆接的接头缺陷,提出运用TRIZ理论进行工艺装置的创新设计。通过构建自冲铆接装置与激光辅助加热系统的技术冲突模型,给出了基于TRIZ理论的4种推荐解决问题发明原理。在分析不同发明原理的基础上,虚拟设计了一种镁合金板材激光辅助加热自冲铆接装置的设计方案。通过UG软件进行运动仿真分析,结果表明:新设计的激光辅助加热自冲铆接装置在上下极限位置没有干涉发生,从而验证了该机构的可行性及有效性。
To control the riveted joint defects of magnesium alloy sheet in self-pierce riveting （SPR） technology at room temperature, the novel SPR device design is proposed based on Theory of the Solution of Inventive Problems （TRIZ）. The technical conflict model between SPR device and laser assisted heating system are constructed, and four recommended principles of invention for solving problems is presented . According to the feasibility of the dif- ferent inventive principles, a new kind of SPR device with laser assisted heating system is obtained. Finally, the motion simulation analysis is carried out by using UG software. The simulation results show that the new design of laser assisted heating SPR device in the upper and lower limit position is not occur interference, the feasibility and effectivity of SPR device with laser assisted system for magnesium alloy sheet is verified.
