The positions of the straightening device, the meter counting device and the traction compression roller can be adjusted according to the diameter of the reaction coil, so that the movement of the wire feeding action and the accuracy of the metering length are ensured, the wire feeding length and speed can be accurately controlled, and stable absorption of a vermicularizing agent is facilitated.

This utility model discloses a hexagonal nut blank cutting device, including a worktable, a placement platform fixedly connected to the top of the worktable, a placement groove formed on the top of the placement platform, a cutter mounted on one side above the placement groove, and a servo motor fixedly connected to the outer wall of the cutter. The hexagonal nut blank cutting device also includes a pushing device. This utility model relates to the field of machining technology. Through the cooperation of a push rod, a bracket, and an electric slider, a controller is used to control the movement distance of the electric slider on the electric slide rod each time. This allows the push rod to precisely drive the blank to move within the placement groove, making the cutting length more accurate. This solves the problem in existing devices where the cutting length of the blank is adjusted by a screw and a screw barrel, which prevents the operator from accurately adjusting the number of rotations of the screw, resulting in deviations in the cutting length of the nut blank and affecting the quality of nut production.
