Insulation paper cutting slot blade

Abstract

The invention relates to an insulation paper cutting slot blade, which comprises a knife handle and a knife part, the knife part comprises a first edge, a second edge and a middle edge, the first edge comprises a first end and a second end, the second edge comprises a first tail end and a second tail end, the middle edge comprises a first end part and a second end part, the second end, the second end part and the second tail part are connected with one end of the knife handle, the middle edge is positioned between the first edge and the second edge and respectively forms cutting parts with the first edge and the second edge, an edge tip of the first end part is lower than the first end and the first tail end, preferentially, a first inclined plane is extended between the edge tip and the upper part of the second end part, a second inclined plate and a third inclined plane are respectively extended between the edge tip and two side parts of the second end part, and the second end part is respectively contacted with the second end and the second tail part. The insulation paper cutting slot blade has the advantages of ingenious design, simple structure and convenient use and can rapidly and simply cut an insulation paper strip, greatly improve the production efficiency and lead the processing to be trim and beautiful, thereby being applicable to industrial large-scale application.

Description

technical field [0001] The invention relates to the technical field of motor processing, in particular to the technical field of stator coil winding processing, in particular to an insulating paper slotting blade. Background technique [0002] The motor is a common electromechanical product in industrial production and daily life. In the structure of the motor, the stator and the rotor are the two major components that make up the motor. Usually, magnets are provided in the rotor, and coils are provided in the stator. The coil is wound on the coil frame of the stator. The outer surface of the coil frame is evenly distributed along the circumference with axial grooves. The coil is wound in the groove. The outer surface of the coil frame is covered with insulating paper, and then the coil is wound. After the coil is wound, a strip of insulating paper needs to be cut from the insulating paper between the two grooves along the axial direction, and then the insulating paper on b...

Problems solved by technology

However, since there is no good way, it is cumbersome to cut a strip of insulating paper between the two grooves along the axial direction. Generally, scissors are used to cut the insulating paper first, and then cut off the excess insulating paper , it needs to be cut twice or more, and it is easy to cut crookedly. If it is damaged, you have to remove the coil and start over again, which is time-consuming and laborious, and it is not beautiful
