Description
Technical Field
The invention belongs to the technical field of wind driven generator production, and particularly relates to an intelligent feeding device and method for stamping a silicon steel sheet of a motor.
Background
The stator core is an important component of the wind driven generator, and mainly plays a role in: when the generator is in a power generation state, magnetic induction lines generated by the rotor form a closed loop, and the electromagnetic lines wound in the tooth grooves of the stator core cut the magnetic induction lines generated by the rotor, so that induced current is generated in the electromagnetic lines. The stator core is of an integral structure, a block structure, a laminated structure and the like. The laminated stator core is generally made of silicon steel sheets. Power losses in the generator include "hysteresis losses" and "eddy current losses". The magnetic hysteresis loop of silicon steel is narrow and small, the magnetic hysteresis loss can be reduced by using the silicon steel as a stator core, and the heating degree is greatly reduced. In order to reduce the "eddy current losses", the core of the generator is laminated with silicon steel sheets insulated from each other, so that the eddy currents pass through a smaller cross section in a long and narrow circuit, so as to increase the resistance on the eddy current path.
At present, silicon steel sheets are mostly formed by cutting a strip material into square materials and then punching and forming the square materials. The traditional method for stamping and feeding the silicon steel sheets of the motor has the defects that firstly, the silicon steel sheets with two specifications cannot be produced by using the same square stock, and the waste material cost ratio is high; secondly, the problem of same plate difference exists, and the phenomenon of uneven thickness is easy to occur when silicon steel sheets are laminated, so that the normal work of the iron core is influenced; and thirdly, the intelligent degree is low, the requirement of continuous stamping production cannot be met, and the production efficiency needs to be improved.
