双动压力机用压边滑块串联四连杆工作机构的优化

摘要/Abstract

摘要： 针对J45-315型闭式单点双动拉延压力机所使用的杆系长度与角度尺寸不合理的机构所造成的外滑块压边过程中位移波动量大，严重影响板材拉延过程中压边效果的问题，建立了该机构的优化数学模型，运用步长搜索法对外滑块的位移波动量进行了优化。优化后的研究结果表明，外滑块位移波动量由原来的0.092mm减小到0.015mm，即压边外滑块位移波动量比原机构减小83.7%时，外滑块压紧角增大3.4%，有效提高了双动拉延机械压力机冲压的工作性能，从而为双动拉延机械压力机压边用外滑块驱动的工作机构优化打下了基础。

Abstract: Concerning the side-pressing effects and large displacement variations in outer sliders conducting side-pressing action by unreasonable lengthes and angles of truss system in J45-315 closed single-point and double-acting drawing press, an optimized mathematical model of the organization was built by using step-length searching method to optimize the variations of displacement shifts. After optimization, the variations are deduced from 0.092mm to 0.015mm, which means the pressing angle adds 3.4% while the variation is decreased to 83.7% of the original. The stamping property of double-acting mechanical press can be effectively increased and it lays a foundation for the optimization of working organizations when double-acting mechanical press conducts side-pressing action driven by outer sliders.

Key words: double-action drawing mechanical press, series four-bar linkage working mechanism, motion characteristics
