双排链条预拉拆节装置设计及研究

Design and Study of Pre-stretching and Disassembling Device for Double-row Chain

针对双排链条制造过程中的预拉拆节环节,设计了一种新型的双排链条预拉拆节装置,该装置包含预拉拆节两大模块:预拉模块采用液压油缸加载,以移动关联链轮进而预拉链轮组间的链条;拆节模块采用气动滑台驱动链条插板稳固链条,气液增压缸驱动冲钉拆除销轴,气缸驱动链条推板推去链板。该预拉拆节机结构合理,标准化程度高,易损件互换性好,能够高效地实现双排链条的动态预拉与拆节。

Aiming at the pre-stretching and disassembling link in the manufacturing process of double-row chain,a new type of pre-stretching and disassembling device for double-row chain is designed.The device consists of two modules of pre-stretching and disassembling.The pre-stretching module uses hydraulic cylinder to load to move the associated sprockets and then pre-stretching sprocket between groups.The disassembling module uses pneumatic sliding table to drive chain insert plate to stabilize the chain,the pneumatic-hydraulic booster cylinder to drive punching nails to remove pin shafts,and the cylinder to drive chain pusher plate to push chain plate.The structure of the pre-stretching and disassembling has high degree of conversion,good in terchangeability of vulnerable parts,can effectively realize the function of dynamic pre-stretching and disassem bly of double-row chain.
