The fixed support door frame 5 comprises a cross beam and a pair of side beams respectively connected to two ends of the cross beam, and the cross beam and the pair of side beams jointly form a door-shaped structure. The beam of the fixed support door frame 5 is connected with the positioning cross rod 1 through the distance adjusting screw rod 2 and the guide screw rod 4, and the part of the guide screw rod 4, which is positioned between the fixed support door frame 5 and the positioning cross rod 1, is sleeved with the damping spring 3.

According to the technical scheme, the rolling straightening block is arranged in the flexible straightening mechanism of the wire straightening device, sliding friction generated when wires are fed is changed into rolling friction by the rolling straightening block, and the friction resistance of the wires is effectively reduced, so that the risk of wire breakage is reduced; meanwhile, the damping spring realizes flexible connection between the fixed door frame and the positioning cross rod and is used for eliminating oscillation of the rolling straightening block caused by non-uniform bending of the wire when the wire is fed at a high speed, so that the straightness of the wire straightening is ensured.
According to a preferred embodiment, the middle part of the positioning cross rod 1 is provided with a distance adjusting threaded hole, the distance adjusting threaded hole is used for connecting the positioning cross rod 1 and the beam of the fixed support door frame 5 together by installing the distance adjusting screw rod 2, wherein the fixed support door frame 5 and the positioning cross rod 1 are subjected to distance changing by screwing in/out the distance adjusting screw rod 2 so as to adapt to straightening of wires with different wire diameters and different strengths.
According to a preferred embodiment, the positioning cross rod 1 is further provided with a pair of guiding threaded holes, and the guiding threaded holes are arranged on two sides of the distance adjusting threaded hole. The guiding threaded holes are used for connecting the positioning cross rod 1 and the beam of the fixed support door frame 5 together by installing the guiding screw rods 4, wherein the guiding screw rods 4 are used for guiding and stably controlling when the fixed support door frame 5 and the positioning cross rod 1 are subjected to distance changing. When a wire enters the wire at a high speed along the rolling straightening block 8, the vibration of the rolling straightening block 8 is easily caused due to the non-uniform bending of the wire, so that the straightness of the wire straightening is poor or the wire is broken.
According to a preferred embodiment, two end portions of the positioning cross rod 1 close to the edges are respectively provided with a mounting hole, and the mounting holes are used for mounting a positioning screw to fix the positioning cross rod 1 on a rotating frame.

Illustratively, two ends of the step shaft 6 are respectively fixed in the clamping grooves of the fixed door frame 5 through two M16 nuts. Meanwhile, since the step shaft 6 is an essential part for supporting the rolling straightening block 8, the thrust bearing set and the pressing spring 9, it is required in practical use that it should have sufficient strength and rigidity.
Thrust bearings, also called thrust bearings, are bearings used to exclusively bear axial forces.

Specifically, the right thrust bearing 70 abuts against the step portion of the step shaft 6, the rolling straightening block 8 abuts between the left thrust bearing 71 and the right thrust bearing 70, the left thrust bearing 71 abuts against the pressure spring 9, and the pressure spring 9 abuts against a side beam of the fixed doorframe 5. Due to the end face stress characteristic of the thrust bearing, the rotational freedom degree of the rolling straightening block 8 can be released, so that the motion state of the rolling straightening block 8 rotating around the shaft is not limited.

The deep groove ball bearing 80 is a common type of rolling bearing, and the basic type thereof is composed of an outer ring, an inner ring, a group of steel balls and a group of cages, and is suitable for high-speed operation. When the wire passes through the wire inlet groove 82 on the surface of the wire inlet wheel 81, the deep groove ball bearing 80 converts the sliding friction between the wire and the wire inlet wheel 81 into rolling friction, and the friction resistance is greatly reduced.
According to a specific embodiment, the surface of the wire feeding wheel 81 is provided with a wire feeding groove 82 with the diameter of phi 4 mm.
According to a preferred embodiment, the wire-feeding wheel 81 is of nylon material. The nylon material is soft, can effectively reduce the risk of scratching and breaking the surface of the wire rod, and is particularly suitable for straightening treatment of the wire rod with higher requirements on dimensional precision and surface smoothness, such as high-strength and high-elasticity titanium alloy, high-temperature alloy wire rods and the like.
