摘　　要：针对非晶合金在室温状态下冷加工性能不佳导致难以对其进行常规冲裁加工,严重限制其在电机领域的应用的问题,提出了一种粘接-冲裁-叠压工艺,以提高非晶合金的室温冲裁能力。首先,将多片非晶合金叠压粘结成具有一定厚度的坯料,然后对非晶合金坯料进行冲裁,最终将冲裁后的成品叠压成铁芯产品。试验证明,该工艺生产的非晶合金成品断面光洁,毛刺高度低于5μm,表面质量满足叠压要求,叠压后的成品满足电机铁芯的制造要求,解决了非晶合金在室温下冲裁质量较差、毛刺较高等问题。Aiming at the problem of poor cold processing performance of amorphous alloy at room temperature,resulting in the difficulty in carrying out conventional punching,which seriously limits its application in motor field,a bonding-punching-stacking process was proposed to improve the punching ability of amorphous alloy at room temperature.Firstly,multiple pieces of amorphous alloys were stacked and bonded into blanks with a certain thickness,and then the amorphous alloy blanks were punched,and finally the finished products after punching were stacked into iron core products.The experiments show that the finished product section of the amorphous alloy produced by this process is smooth,the burr height is less than 5μm,and the surface quality meets the stacking requirements,and the finished product after stacking meets the manufacturing requirements of the motor iron core.It solves the problems of poor punching quality and higher burr of amorphous alloy at room temperature.
