[0035] See also Figure 1-7 The present invention provides a hanger bending and forming device, comprising a frame 1, a first bending and forming mechanism 2, a second bending and forming mechanism 3 and a conveying mechanism 4, wherein the first bending and forming mechanism 2 and the second bending and forming mechanism 3 are respectively installed at the upper and lower ends of the front face of the frame 1, and the iron wire is bent by the first bending and forming mechanism 2 and the second bending and forming mechanism 3 to obtain an initial hanger, and the conveying mechanism 4 is vertically installed at the center of the front face of the frame 1, and the iron wire is moved up and down by the conveying mechanism 4 so that the iron wire reaches the processing position, and the upper and lower ends of the front face of the frame 1 are respectively installed with a quality monitoring mechanism 6 and a preheating mechanism 5;

[0036] The preheating mechanism 5 includes a box body 51 installed transversely at the bottom end of the front face of the frame 1, a motor 52 is installed at the center position of the rear side of the box body 51, a gear 53 is installed at the output end of the motor 52, guide rods 54 are installed transversely at the upper and lower ends of the inner cavity of the box body 51, and slides 55 are sleeved at the left and right ends of the outer wall of the guide rod 54, and the slide 55 is constrained to move transversely by the guide rod 54, and a rack 56 meshing with the gear 53 is installed transversely on the rear side of the slide 55, and the two racks 56 are respectively located at the upper and lower ends of the gear 53. When the gear 53 rotates, the two racks 56 move in opposite directions, so that the two slides 55 can move inward or outward at the same time, and one end of a connecting rod 57 is installed on the front side of the slide 55, and a heating component 58 is installed on the other end of the connecting rod 57. The heating component 58 heats the iron wire to soften the iron wire.

[0037] As a preferred solution, further, the heating component 58 includes a cylinder 581 installed at the front end of the connecting rod 57, an inductor 582 is arranged inside the cylinder 581, and the inductor 582 is spirally distributed inside the cylinder 581 from left to right. When the inductor 582 is energized, a changing magnetic field is generated. When the magnetic field passes through the iron wire, an induced electromotive force is generated in the iron wire, and an eddy current is formed in the iron wire, which quickly heats the iron wire. A plurality of limit sleeves 583 are equidistantly installed from left to right in the inner cavity of the cylinder 581. The limit sleeves 583 are conical in shape, which limit the iron wire so that the iron wire is located at the center of the cylinder 581, thereby improving the heating efficiency of the iron wire.

The distance between the two heating components 58 gradually decreases or increases, and the cylinder 581 is sleeved on the outer wall of the wire or moves away from it. When the cylinder 581 wraps the wire, the limit sleeve 583 allows the wire to be in the center of the cylinder 581, and the inductance coil 582 generates a changing magnetic field, which generates eddy currents in the wire to heat the wire.

The trigger rod 633 is spline-shaped to prevent the trigger rod 633 from rotating. The trigger rod 633 moves forward under the elastic force of the spring piece 632. A contact unit 634 electrically connected to the alarm light 62 is laterally installed on the right inner wall of the sleeve 631.

The outer rod 6342 is pushed to move left under the elastic force of the spring 6343, and a rotatable roller 6344 is installed on the left end of the outer rod 6342. A contact 6345 is installed on the left inner wall of the shell 6342 and the left end of the inner rod 6341, and the contact 6345 is electrically connected to the alarm light 62. When the trigger rod 633 moves backward, the trigger rod 633 squeezes the roller 6344 on the right side at an angle, causing the two contacts 6345 to contact, and the alarm light 62 is powered on to emit light, so as to remind the unqualified points of the molded hanger;

[0042] Hanger quality inspection: Once the hanger touches the trigger rod 633, the trigger rod 633 moves backward, and the inclined surface of the trigger rod 633 squeezes the roller 6344 to the right. The outer rod 6342 moves right along the inner rod 6341 and squeezes the spring 6343. When the roller 6344 reaches the right plane of the trigger rod 633, the two contacts 6345 contact each other, and the alarm light 62 is powered on and illuminated, indicating that the hanger is deformed at this position and needs to be adjusted.
