Problems solved by technology

At present, for the manufacturing process of the motor stator core with positioning slots and special shapes, only simple punching is used to make the iron chips stacked and connected to each other to form the iron core, but this manufacturing method makes the concentricity between the iron chips relatively low. Poor, resulting in poor dynamic balance when the iron core works, so the inventor finally has the manufacturing process of the present invention in view of the above-mentioned defects

Embodiment

[0025] Such as figure 1 with figure 2 As shown, the iron core manufacturing process of a new energy vehicle motor described in this embodiment includes the following steps:

[0026] In step S1, the material strip 100 is conveyed to the blanking direction in a continuous step-by-step manner between the upper die and the lower die of the continuous blanking die, wherein a continuous step is formed between the upper die and the lower die of the continuous blanking die. The continuous stepping punching station includes the first punching station 101 for punching the guide hole 3 and the forming hole, and the first punching station 101 for punching the ventilation hole 4 from the feeding to the blanking direction. The second punching station 102, the third punching station 103 for punching the first through hole 6, the fourth punching station for punching the first magnetic steel groove 9, the rotor buckle point 7 and the through hole 8 The punching station 104, the fifth punchi...

Abstract

According to the manufacturing process of the iron core of the motor for the new energy automobile, the material strip is continuously blanked between the upper die and the lower die of the continuous blanking die to form the motor rotor iron core and the motor stator iron core with the positioning groove, so that the blanking forming efficiency is high, and the motor iron core with the positioning groove and a special-shaped structure is not prone to deformation. According to the motor iron core, the iron core sheets are rotated after being formed, so that the concentricity between the iron core sheets of the formed motor iron core is good, the dynamic balance during working is good, and meanwhile, the formed motor iron core is small in size, light in weight and capable of meeting the performance requirement of the motor stator iron core.

Description

technical field [0001] The invention relates to the technical field of a motor iron core manufacturing process for a new energy vehicle, in particular to a manufacturing process for a motor core for a new energy vehicle. Background technique [0002] At present, new energy vehicles are vigorously promoted and further popularized, especially electric vehicles. For new energy vehicle drive motors, the stator core and rotor core are the heart of the motor, and their manufacture has always been popular. focus on. At present, for the manufacturing process of the motor stator core with positioning slots and special shapes, only simple punching is used to make the iron chips stacked and connected to each other to form the iron core, but this manufacturing method makes the concentricity between the iron chips relatively low. Poor, resulting in poor dynamic balance when the iron core works, so the inventor finally has the manufacturing process of the present invention in view of the...
