Detailed Description
The utility model is described in more detail below with reference to the accompanying drawings. A square groove motor slot piece cutting mechanism is characterized in that: the cutter comprises a cutter seat 1, a back cutter seat 2 and a cutter seat 3 movably arranged between the cutter seat 1 and the back cutter seat 2, wherein a first cutting opening is formed between a lower cutting edge 31 and the cutter seat 1, a second cutting opening is formed between an upper cutting edge 32 and the back cutter seat 2 on the cutter seat 3, a feeding channel 4 is arranged on the cutter seat 1, and a groove piece 5 is fed through the feeding channel 4 and is cut off by the cutter seat 3.
The section of the feeding channel 4 is in a trapezoid groove shape, the feeding channel 4 penetrates through the upper end face and the lower end face of the cutter seat 1, and the groove piece 5 is pushed upwards from the bottom of the feeding channel 4.
The lower cutting edge 31 is positioned on the upper surface of the feeding channel 4 to slide, and a first fracture is formed between the lower cutting edge 31 and the feeding channel 4.
The back knife rest 2 is provided with a back knife edge 21 towards the feeding channel 4, and a second cutting opening is formed between the back knife edge 21 and the upper cutting edge 32.
