摘要：端子裁切机主要是对电镀好的端子料带进行送料、折弯和定长切断。主要有送料部分、裁切部分、动力折弯部分、电控部分等构成。裁切机根据所受到的指令快速裁切，自动化程度高，操作简单。是目前很多端子裁切行业所采用的裁切设备。19976
本次设计内容为端子裁切机的送料工站部分。该工站是主要工序中的第一步，主要完成端子的自动送料，以满足折弯和裁切工站的需要。应制定合理的时序图以确保送料、裁切、折弯三工序互不干涉，设计送料部分的驱动方案及机械结构，设计确保时序图正常运转的控制方案。其中主要解决了自动定长送料并且送料长度可调的问题，能自动控制送料、裁切、折弯工序的正确时序，保证先送料，然后折弯裁切，并且传感器与PLC控制器互相配合，做到各工序无不影响又提高生产效率。最后得出可以为端子裁切机送料工站的选择和使用提供参考。

    Terminal cutting machine - feeding work station design
Abstract : Terminal cutting machine mainly for terminal plating material with good conduct feeding, folding and fixed-length cut . There are feeding part , cutting part , power folding part , electronically controlled part and the like. Fast cutting cutting machine according to the instruction by the high degree of automation , simple operation. Many terminal devices is cut using cutting industry .
The content is designed to feed the terminal cutting machine work station parts. The work station is the first major step , the main terminal to complete automatic feeding, in order to meet the needs of bending and cutting work stations. Timing diagram should be developed to ensure reasonable feeding, cutting , bending three processes noninterference , design -driven solutions deliver the material part and mechanical structure , control scheme designed to ensure the normal operation of the timing diagram . The main solution to the automatic feeding and length adjustable length feeding problems , can automatically control the feeding, cutting , bending process right timing to ensure that the first feeding, then bend the crop , and the sensors and PLC controller with each other , do all affect each process and improve productivity. Conclusion that can work station for feeding terminal cutter selection and use for reference.
Keywords : Terminal cutters ; feeding work stations ; timing diagram ; fixed-length feeding ; PLC.
