A high-stability single-drawing mechanism for cold-drawn alloy wires comprises a feeding device 10, a guide straightening device 20, a pretreatment device 30, a roller type drawing device 40 and a discharging device 50. The wire rod is wound on the feeding device 10, and one end of the wire rod passes through the feeding device 10, the guide straightening device 20, the pretreatment device 30, the roller type stretching device 40 and the discharging device 50 in sequence. It is understood that the single-drawing mechanism for high-stability cold-drawn alloy wire includes other functional components and specific structures, which are well known to those skilled in the art, and therefore, will not be described in detail herein.

The feeding device 10 comprises a feeding rotating disc 11 and a feeding support 12 arranged on the feeding rotating disc 11, and the wire rod is wound on the feeding support 12. When the roller type stretching device 40 is driven, a force can be applied to the wire, and the feeding support 12 is pulled to rotate on the feeding rotating disc 11. The feeding device 10 enables the feeding direction to be stable and reliable by arranging the feeding rotating disc 11 and matching with the feeding bracket 12 to rotate.

The guide straightening device 20 comprises a vertical connecting plate 21 arranged on one side of the support frame 41, at least four straightening wheels 22 which are arranged in a vertically staggered mode and are arranged at intervals in the horizontal direction, and a straightening driving mechanism 23 for driving the straightening wheels 22 to rotate. The straightening driving mechanism 23 drives the straightening wheels 22 to rotate rapidly and guides and extrudes the wire passing through the straightening wheels 22, so as to initially straighten the straightness of the wire. The straightening driving mechanism 23 includes a driving shaft inserted into the straightening wheels 22, and a driving motor, the structure of which is omitted in the drawings.

The pretreatment device 30 comprises a powder suction groove 31 arranged between the vertical connecting plate 21 and the support frame 41, two feeding and discharging holes 32 arranged at two ends of the powder suction groove 31, and lubricating powder 33 arranged in the powder suction groove 31. The wire rod passes through the guide straightening device 20 and then passes through the material inlet and outlet hole 32 to pass through the powder pumping groove 31, the surface of the wire rod becomes finer and smoother after passing through the lubricating powder 33, and the passing performance of the wire rod is improved when the wire rod is clamped and stretched subsequently.

The roller type stretching device 40 comprises a support frame 41, a rotating shaft 42 vertically penetrating through the support frame 41, a rotary driving mechanism 43 arranged at the upper end of the support frame 41 and driving the rotating shaft 42, a stretching roller 44 arranged on the rotating shaft 42, and two limiting rollers 45 arranged at the outer side of the stretching roller 44 at intervals, wherein a limiting adjusting structure 60 is arranged between the limiting rollers 45 and the support frame 41. The limiting adjustment structure 60 comprises a horizontal driving mechanism 61 arranged on the support frame 41, and a push rod 62 driven by the horizontal driving mechanism 61, and the limiting roller 45 is arranged at one end of the push rod 62 far away from the horizontal driving mechanism 61. The rotary driving mechanism 43 drives the rotating shaft 42 to drive the stretching roller 44 to rotate rapidly, and the linear speed of the stretching roller 44 is greater than the linear speed of the straightening wheel 22, so that the wire is forced to be wound on the stretching roller 44. The horizontal driving mechanism 61 drives the push rod 62 to move toward the stretching roller 44, and the limit roller 45 is forced to approach the outer wall of the stretching roller 44. By the drawing roller 44 being close to the drawing roller 44, force is applied to the wire, and the wire is forced to be close to and wound on the outer wall of the drawing roller 44. The limiting rollers 45 on the two sides form clamping for a part of the wire wound on the stretching roller 44, the stretching roller 44 capable of rotating rapidly stretches the wire, and the limiting rollers 45 well guarantee the passing performance of the wire. When one end of a wire is fixed on the blanking device 50, the length of the limiting roller 45 is smaller than that of the stretching roller 44, the upper end of the limiting roller 45 is flush with the upper end of the stretching roller 44, the wire is wound on the stretching roller 44, the outer side of the wire is limited and fixed through the limiting roller 45, the wire continuously moves towards one side of the blanking device 50 until the wire wound on the stretching roller 44 is controlled to be separated from the limiting roller 45, and the wire can be fed onto the blanking device 50.

The blanking device 50 comprises a blanking rotating disk 51 arranged below the stretching roller 44, and a blanking bracket 52 arranged on the blanking rotating disk 51 and the upper end of which is connected with the rotating shaft 42 through a detachable structure 70.
