[0028] After the equipment is started, the feeding mechanism straightens the steel wire from the front end and conveys it backward along the direction set by the equipment; the steel wire is guided by the guide hole 701 on the support plate 7, and the steel wire is in a horizontal suspension state. The shear plate 8 performs a shearing action with the support plate 7 under power drive to cut the steel wire according to a predetermined length; the cut steel wire falls on the workbench 2, and the movable push plate 10 slides on the horizontal guide plate 9 to push the steel wire from the workbench 2 to the thread rolling mechanism; the steel wire is pushed between the fixed tooth plate 11 and the movable tooth plate 12, and the movable tooth plate 12 moves up and down relative to the fixed tooth plate 11 under the drive of the transmission mechanism to complete the thread rolling operation, so that the required threads are formed at both ends of the steel wire, and the preparation for the manufacture of U-bolts is completed.

[0029] The driving device provides power, and the transmission mechanism transmits the power to the various actuators of the feeding mechanism, the cutting mechanism, the pushing mechanism and the thread rolling mechanism, coordinating them to work in sequence and in an orderly manner according to the process requirements. The transmission mechanism includes multiple transmission shafts, gear sets, connecting rods, and cams. Those skilled in the art can easily combine and apply them according to the process requirements to achieve the corresponding functional actions, such as Figures 1 to 6 shown.

[0030] The above-mentioned equipment realizes fully automated operation from feeding, cutting, pushing to thread rolling, improves production efficiency, is simple and convenient to operate, reduces manual intervention, and reduces labor intensity; through precise cutting mechanism and transmission mechanism, the accuracy of the cut length of the wire material and the thread rolling position is ensured.

[0031] In some embodiments, the main machine 1 is provided with a guide groove, and the movable tooth plate 12 slides up and down in cooperation with the guide groove. The cooperation between the guide groove on the main machine 1 and the movable tooth plate 12 enhances the stability of the thread rolling mechanism during the thread rolling process, and further improves the processing accuracy of the product.

[0032] In some embodiments, the movable push plate 10 pushes the steel wire material to contact the movable die plate 12, and the movable die plate 12 moves downward under the drive of the transmission mechanism, and cooperates with the fixed die plate 11 to roll the steel wire material until the steel wire material moves to the lower end of the fixed die plate 11 and falls down, completing the material preparation. As the movable die plate 12 continues to move downward, the steel wire material gradually moves to the lower end of the fixed die plate 11 during the rolling process. When the steel wire material is finished rolling, due to the effect of gravity, the steel wire material falls from the lower end of the fixed die plate 11, indicating the completion of the material preparation process; through the precise cooperation of the movable push plate 10 and the movable die plate 12, the position accuracy of the steel wire material during the rolling process can be ensured, thereby improving the processing accuracy of the product.

[0033] In some embodiments, the rear side of the shear plate 8 is connected to a support rod 14, and the support rod 14 is connected to an anti-warping pressure plate 15, and the lower end of the anti-warping pressure plate 15 is flush with the lower end of the shear plate 8. The lower end of the anti-warping pressure plate 15 is flush with the lower end of the shear plate 8, ensuring that the steel wire material will not be warped or deformed due to uneven force during the shearing process, thereby improving the shearing accuracy.

[0034] In some embodiments, the feeding mechanism 6 includes a horizontal straightening wheel assembly 16, a vertical straightening wheel assembly 17, and a clamping drive wheel assembly 18. The clamping drive wheel assembly 18 drags the steel wire from front to back under the drive of the transmission mechanism, so that the steel wire passes through the horizontal straightening wheel assembly 16, the vertical straightening wheel assembly 17, and the guide hole 701 in sequence. Through the straightening effect of the horizontal straightening wheel assembly 16 and the vertical straightening wheel assembly 17, the steel wire material is fully straightened during the feeding process, thereby improving the straightness of the steel wire material. The precise guiding effect of the guide hole 701 further improves the accuracy and stability of the feeding.

[0035] In some embodiments, the rolling surface of the fixed tooth plate 11 is an inclined surface, and the interval between the rolling surface and the movable tooth plate gradually increases from top to bottom. The inclined surface design makes the force applied to the steel wire material gradually increase during the rolling process, rather than suddenly applying a large force, thereby reducing the risk of damage to the steel wire material.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
