|
摘要
针对东莞市Y企业钢铁线材工厂调直切断机线材质量精度较低的问题,提出调直切断机定长切断机构的改进方案。在调直机机械定长结构的基础上,详细分析定长切断系统存在较大误差的主要原因,同时,结合当前光电检测与传感器技术以及相关机械机构的衔接性,设计出一套新型定长切断系统帮助企业解决实际问题。通过工艺改进实证应用结果表明,该系统具有稳定性好、可靠性高、质量精度高等特点,能够较大程度地减小定长切断误差,实现线材精确定长,提高生产效率。由此表明改进后的工艺具有一定的实用价值,对同行工艺改进具有指导意义和参考价值。
Aiming at improving the wire quality precision of straightening and cutting machines in an armature wire factory in Dongguan, this paper proposes an improvement program of the fixed-length-cutting mechanism of straightening and cutting machines. On the basis of mechanical fixed-length mechanism of the straightening and cutting machines, the main reasons for higher errors in the fixed-length-cutting system are detailedly analyzed.Meanwhile, a new system of cut-to-length combining photoelectric detection and sensor technologies with the link of related mechanical mechanism is designed to solve enterprises' practical problems. With the application of real evidence through process improvement, the results indicate that this system has such features as sound stability, high reliability and superior quality precision, etc., which can reduce the errors of fixed-length-cutting and maintain precise fixed-length to improve productivity. It can be seen that the improved process has certain practical value, providing peer companies with implication and reference.
