一、目前国内电机模具材料的使用简况电机模具所冲切的材料,一般均系硅钢片。它比普通低碳钢具有较高的抗剪强度和较高的表面硬度(因表面冷作硬化),每台电机所用硅钢片数量较多,批量也较大,同时对冲制的质量、尺寸公差、剪切边的平整程度(如毛刺)要求较高。模具材料性能的好坏,直接影响电机生产的质量和产量任务的完成。电机生产要多、快、好、省,模具质量的好坏具有重要意义。影响模具质量好坏
First, the current situation of the use of motor mold material Die cut by the motor die, are generally silicon steel sheet. It has higher shear strength and higher surface hardness (due to surface hardening) than ordinary mild steel. The number of silicon steel sheets used per motor is large and the batch size is also large. At the same time, the quality and dimensional tolerance of hedging , Cutting edge formation (such as burr) higher requirements. Mold material performance is good or bad, a direct impact on the quality of motor production and the completion of the task of production. Motor production to be more, faster, better, provincial, the quality of the mold is of great significance. Mold quality is good or bad
