冲压制件可追溯技术研究与应用

Research and Application of Traceability Technology for Stamping Parts

为了实现冲压件质量问题的可追溯管理,分析了模具机械打码技术以及设备激光打码技术的结构、原理及应用的优缺点。机械打码安装在模具上,在线更换需要生产线停机,打码时间精确到周;激光打码与生产线集成,不需要停线换标,打码信息精确到零件。根据不同的应用条件选择不同的打码方式,满足冲压件从单批次到单件的打码精准质量可追溯控制。同时通过数字化手段贯通各领域打码信息,实现从冲压专业到整车质量可追溯信息绑定的跟踪。

In order to achieve traceability management of quality issues in stamping parts,the structure,principles,and advantages and disadvantages of mold mechanical coding technology and equipment laser coding technology were analyzed.Mechanical coding is installed on the mold,and online replacement results in production line shutdown.The coding time is accurate to weeks;Laser coding is integrated with the production line,without the need for stopping the production line to change labels,and the coding time is accurate to the parts.Different coding methods were selected according to different application conditions to meet the precise quality traceability control of stamping parts from single batch to single piece.At the same time,through digital means,various fields of coding information are connected,achieving tracking from stamping profession to vehicle quality traceability information binding.
