【目的】研究指榫对接所需端向压力(指接压力)与榫型参数和嵌合度的关系,探讨榫型、嵌合度、指接压力对指榫胶接力学性能的影响规律,以获得较佳的指榫胶接工艺。【方法】采用5种不同型号的指榫铣刀,分别将兴安落叶松层板的一端加工成具有不同嵌合度的垂直型指榫,将两指榫对接并在力学试验机上加压至齿顶和槽底紧密接触,读取其压力值(各种榫型和嵌合度的试件各10对),研究指榫对接所需端向压力(指接压力)与榫型参数和嵌合度的关系;对指榫进行手工涂胶(双面施胶,施胶量为180 g·m~(-2)),根据测试得到的指接压力对各种榫型和嵌合度的开榫木板进行对接加压胶合,试件放置24 h后按照GB/T 26899—2011《...

Objective: In order to obtain the optimization processing parameters of finger-jointing, the relationship of tenon's end pressure (finger-jointing pressure), fitness ratio and it's type was clarified, and the impact of tenon type, fitness ratio and finger-jointing pressure on its mechanical properties was also investigated. Method: Using five different types of cutter to process Larix gmelinii lamina into vertical type finger-jointing tenon with different fitness ratio. Pressing two finger-jointing tenons together until the addendum contacts the groove bottom closely at mechanical machine, obt...
