[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional profiling cutting device for fastener production, which usually requires manual assistance to adjust the cutting during the cutting process, the operation is more troublesome, resulting in low cutting efficiency. By setting the limit assembly, cutting assembly and punching assembly, the processing plate can be automatically clamped, cut and punched without manual operation, which is more efficient than the traditional cutting device that requires manual assistance.

By placing the end of the processing plate on the second clamping plate, the first clamping plate is adjusted to fit closely with the surface of the processing plate, and then the nut is tightened to fix the first clamping plate. For wider processing plates, the second clamping modules on the left and right sides of the first clamping module can be used for auxiliary clamping and fixing, so that the limit assembly can be suitable for processing plates of different widths. The electric push rod can be controlled to move by the telescopic cylinder to adjust the distance between the two relatively set groups of limit assemblies, so that the limit assembly can be suitable for processing plates of different lengths. The first driving motor can be set to drive the threaded rod to rotate, and then the slider can slide along the surface of the threaded rod, so that the first clamping module and the second clamping module can drive the processing plate to move back and forth to adapt to the position of the upper profiling assembly, cutting assembly and punching assembly.

[0014] 2. The processing plate can be cut by setting a cutting assembly, and the turntable can be driven to rotate by setting a second driving motor, so that the cutting head and the punching head can rotate in the horizontal direction. The first swing arm, the second swing arm and the fourth connecting block can be driven to rotate by setting a third driving motor, a fourth driving motor and a fifth driving motor, so that the cutting head and the punching head can rotate in the vertical direction to adjust the position and angle. The cutting head and the punching head can be driven to rotate and cut and punch by setting a sixth driving motor. The cutting assembly and the punching assembly that can rotate arbitrarily in the horizontal and vertical directions can make cutting and punching more flexible. By setting a profiling assembly, the cutting head can cut fasteners of corresponding shapes and sizes along the shape of the profiling holes on the profiling frame. By setting a protective layer on the inner side of the first clamping plate and the second clamping plate, a certain buffering effect can be achieved to prevent the processing plate from being damaged by excessive clamping force.
