实木弯曲工艺的研究
摘要:弯曲木的制造技术在某种程度上决定其发展方向。目前，国内加工弯曲零部件的方法均存在自己的缺点和不足，如机械加工方法的原料浪费问题和化学加工方法的环境污染问题。本研究通过物理加工技术即水煮加热软化木材，分析软化温度、压力和时间等工艺参数对试件弯曲效果的影响，确定最佳软化工艺，为工业化生产提供理论参考。
采用工业上最容易实现的水热软化法来软化木材，考察改变工艺条件对杨木的纵向拉、压性质的影响。试验设计以水温、保温时间和冷却时间等作为试验中考虑的影响因子，采用优化设计得出最优软化结果以此研究杨木的弯曲可行性情况。

Abstract ：Curved wood furniture has its own characteristics which have been increasingly appreciated by customers. Now there are some obvious defaults in the domestic way to make curved product such as the waste of material during the production and environment pollution which caused by chemical process. In the paper, physical method to soften wood samples has been studied and the softening temperature, softening press and softening time which have influence on the effect of curved samples have been analyzed to acquire the optimum technological parameters. The paper can be served as reference to the theoretical basis on producing cured wooden furniture in the factories.
Adopt the hot water to soften wood that can be realized easily on the industry, review the influence of changing technology conditions on the property of longitudinal tension and compression. The experiment design takes the water temperature, heat preserving time and cooling time as the influence factors. Adopt the optimizing design to find out the best result, the thesis studies the bend and recovery of poplar after compressed.
