When in use, the clamping and positioning component 9 is controlled to clamp and position the steel bar body 2 on both sides of the cutting position, so that the cutting process of the steel bar body 2 is more stable, thereby making the incision of the steel bar body 2 smoother and the processing quality of the steel bar body 2 higher. After the steel bar body 2 is cut, the two sections of the steel bar body 2 are driven to move to both sides by the elastic side push component 6 to avoid the contact between the incision position of the steel bar body 2 and the cutting knife 404 to cause material collapse, thereby improving the safety of operation.

[0023] The transverse push cutter assembly 4 includes a transverse push rod 401, which is fixedly installed in the cutting operation box 3 through a connecting block 402. A U-shaped mounting seat 403 is fixedly installed on the telescopic end of the transverse push rod 401. A cutting knife 404 is rotatably installed on the inner wall of the U-shaped mounting seat 403, and the cutting knife 404 is fixedly connected to the output shaft of the built-in motor of the U-shaped mounting seat 403.

Before controlling the clamping and positioning assembly 9 to clamp and fix the steel bar body 2, the first connecting slide bar 602 and the second connecting slide bar 603 are controlled to slide inward in the transverse mounting groove to compress the side thrust spring 604. After the steel bar body 2 is cut off, the side thrust spring 604 is reset to make the two sections of the steel bar body 2 move to both sides to avoid the problem of material collapse caused by the incision of the steel bar body 2 and the cutting knife 404 being in contact with each other.
