定子引出电缆线的接头,我厂过去用铅锡焊条焊接。但由于锡供应较紧张,而且锡焊工艺有如下缺点:(1)质量不稳定,当焊接时若垃圾未清除干净,易造成假焊现象;(2)电机运行时,因故障发热锡易熔化脱落;(3)助焊剂有腐蚀性,影响使用寿命;(4)工作场地有烟雾和有害气体,劳动条件差。因此,为了保证产品质量、节约用锡及劳动保护等要求,我厂开始在部分产品上试验定子电缆线接头使用冷压接。冷压接一般使用冷压钳。冷压钳有手动的、油压的、也有气动的。冷压接的实质是利用压力使工件的被接部位产生塑性变形,使导线与端子紧密接触。 Stator leads to the cable connector, I used to solder the factory with lead-tin welding. However, due to the tight supply of tin, the soldering process has the following disadvantages: (1) the quality is not stable, and if the garbage is not cleaned when soldering, it may easily cause false soldering; (2) when the motor is running, the hot tin is easily melted Off; (3) corrosive flux, affecting the service life; (4) workplace smoke and harmful gases, poor working conditions. Therefore, in order to ensure product quality, saving tin and labor protection and other requirements, I plant began to test the stator cable connector on some products using cold crimping. Cold crimping commonly used cold clamp. Cold pressure clamp manual, hydraulic, but also pneumatic. The essence of cold crimping is the use of pressure to plastic parts of the workpiece was plastic deformation, the wire and the terminals in close contact.
