The second electric push rod (35) retracts and drives the bending plate (36) to rise and reset. The first electric push rod (32) retracts and drives the pressure plate (34) to rise. The wire feeding mechanism feeds the titanium wire again, causing one end of the titanium wire to protrude from the support rod (28) by the preset length. Repeat S2 and the above steps until the protruding part of the titanium wire is bent into a U-shaped structure. S4: Fine adjustment of titanium wire bending angle: During the pressing down of the bending plate (36) in S3, the sliding rod (37) slidably connected to the bottom end of the bending plate (36) moves towards the support rod (28) under the elastic force of the spring (38). Initially, the spring (38) is in a compressed state, and one end of the sliding rod (37) is flush with the bending plate (36). The sliding rod (37) pushes the titanium wire towards the rotating plate (39) at the bottom end of the support rod (28), so that both ends of the titanium wire bend along the inclined surface of the rotating plate (39) to achieve a larger bending angle. If adjustment is needed... The bending angle can be adjusted by rotating the screw (310) through the operating block (311). The screw (310) moves back and forth along the bottom end of the outer surface of the support rod (28), pushing the rotating plate (39) to rotate around the bottom end of the support rod (28) until the rotating plate (39) is adjusted to the target tilt angle, thereby changing the bending angle of the titanium wire. When the bending plate (36) rises and resets, one end of the slide rod (37) contacts the surface of the support rod (28) and the rotating plate (39) and is squeezed to move towards the spring (38). The spring (38) is compressed again to store force for the next bending. S5: U-shaped titanium wire cutting and separation: Start the two third electric push rods (42) of the cutting mechanism, fix the two L-shaped rods (41) on both sides of the support rod (28), install the third electric push rod (42) on the outer surface of the L-shaped rod (41), and the two third electric push rods (42) extend synchronously, pushing the cutting blades (43) at their respective output ends to move in the same direction to the root of the titanium wire U-shaped structure. The cutting blades (43) cut the titanium wire from the root to form a single U-shaped titanium nail; S6: Finished titanium nail discharge: The cut U-shaped titanium nails fall into the discharge trough (5) fixedly connected to one end of the outer surface of the machine body (1) under the action of gravity, and are transported to the subsequent collection or processing stage through the discharge trough (5).
