往返式裁板锯的设计 摘要 裁板锯是现代木工机械中很通用设备，在实木板、刨花板、胶合板、纤维板等人造板的切割上都有很优异的表现，在车船制造和家具制造等木工加工行业中都广泛应用。根据市场的需求，本设计了一台用于切削锯材的往返式裁板锯。它包括机体、电动机、气缸、锯架台、滚轮、主锯、划线锯、减速器。其中主锯、划线锯和减速器都有各自的电动机；在机身的上梁处有两个圆柱导轨；在锯架台部分设有主锯、划线锯和它们的电机；锯架台的运动靠四个滚轮，四个滚轮和圆柱导轨也相配合；在切削运动的终点处有卷筒、减速器和牵引电动机；牵引电机靠钢丝绳实现切削运动的进给；因此裁板锯需要实现往返运动，在往返过程中锯切系统需要下降，因此锯架台处还设有气缸来实现切削系统的升降，锯架升降板和气缸活塞杆铰接。本设计的裁板锯结构简单合理，具有较高的性价比，能满足市场的大部分需求，切割废屑也不容易卡机，机体的刚性足以满足工作范围内的需要。 关键词：往返式裁板锯；锯架台；气缸 英文摘要 The desig
