新能源汽车高压线护套剥离力的工艺控制

Process Control of Sheath Strip Force of High-Voltage Cable for New Energy Vehicles

新能源汽车高压线的护套剥离力直接影响电缆组件的加工质量和效率。针对新能源汽车高压线护套剥离力的适宜范围较窄、工艺控制难度较大,对其工艺控制要求、工艺影响因素、工艺控制措施展开了研究。通过对护套材料、模间距、模套尺寸、挤出后电缆温度等影响因素的工艺控制,最终实现了护套剥离力的有效控制。同时,创新方法使工艺控制仅需对模间距、模具尺寸进行检验即可,操作过程简单、调试效率高、线材浪费少。

The sheath strip force of high-voltage cables for new energy vehicles directly affects the processing quality and efficiency of cable assemblies.A study is conducted on the process control requirements,process influencing factors,and process control measures for the narrow suitable range and the high process control difficulty of sheath strip force of high-voltage cables for new energy vehicles.By controlling the process of influencing factors such as sheath material,mold spacing,mold sleeve size,and cable temperature after extrusion,effective control of sheath strip force is ultimately achieved.At the same time,innovative methods enable process control to only require inspection of mold spacing and mold size,resulting in a simple operation process,high debugging efficiency,and minimal cablewaste.
