[0028] Working principle: The utility model is a thread rolling device. During use, the operator only needs to place the screw on the lower scrubbing plate 7, and then rotate the rocking wheel 26 to adjust the height of the upper scrubbing plate 14. The rocking wheel 26 drives the worm 22 to rotate through the rotating rod 23. The worm 22 drives the threaded tube 20 to rotate in the inner cavity of the first bearing 19 and the outer side of the threaded rod 18 through the worm wheel 21. The threaded rod 18 moves relative to the threaded tube 20 under the action of the thread. The threaded rod 18 drives the upper mounting plate 13 and the upper scrubbing plate 14 to move, thereby adjusting the height of the upper scrubbing plate 14. Then, the upper scrubbing plate 14 is adjusted. 4, first unscrew the second screw 15, unfasten the fixation of the upper washboard 14, and then move the upper washboard 14 horizontally, so that the upper washboard 14 is horizontally moved to a suitable position, and then the second screw 15 is passed through the second through hole 16 and tightened in the corresponding second screw hole 17. In this way, the horizontal position adjustment of the upper washboard 14 is completed. Compared with the prior art, when the device adjusts the height of the upper washboard 14, the threaded rod 18 drives the upper washboard 14 to move up and down within a limited track, and there will be no left and right shaking, thereby ensuring the normal progress of the thread rolling work;

[0029] Finally, the hydraulic press 12 is started, and the start of the hydraulic press 12 realizes the reciprocating motion of the lower wash plate 7 in the horizontal direction, that is, the thread rolling operation of the screw is realized;

[0030] When the lower washboard 7 and the upper washboard 14 need to be replaced or repaired, it is only necessary to unscrew the first screw 8 and the second screw 15 to release the fixation of the lower washboard 7 and the upper washboard 14, and then replace or repair the lower washboard 7 and the upper washboard 14. Through the setting of the wear-resistant strip 28, the friction force on the side of the lower washboard 7 and the upper washboard 14 close to the screws is greater, which greatly improves the service life of the lower washboard 7 and the upper washboard 14.
