Preferably, the gear spacer is further arranged on the large gear, and the large gear abuts against the deep groove ball bearing through the gear spacer.

Preferably, the speed reducer shaft of the worm gear speed reducer motor is linked with the large gear through the intermediate gear.

Preferably, the other end of the hollow shaft is in running fit with the aluminum alloy seat sleeve through a four-point hinged ball bearing.

Preferably, O-shaped rings are arranged at the contact parts of the hollow shaft and the aluminum alloy seat cover.

Preferably, the worm gear speed reducing motor is further provided with a handle.

In summary, the utility model has the following advantages:

the novel rotary die box adopts a transmission mode of connecting gears of the worm and gear reducer, improves the reliability of rotation, effectively shortens the distance from the die to the outlet of the die box, and avoids the situation that the wire pressing roller cannot effectively reduce the vibration of the steel wire in the high-speed drawing process; in addition, the die is designed to be installed in an open mode, a plurality of oil seals and O-shaped rings ensure tightness of the die in cooling water, and in order to facilitate replacement of the die, a handle can be additionally arranged on the speed reducing motor, so that the opening of the die installation cavity can be conveniently rotated to the most convenient to detach position.

In conclusion, the utility model can effectively solve the problem that the traditional direct water-cooling die box die cannot rotate, and solves the problems that the traditional rotary die box has poor cooling effect, complex structure, easy generation of slub yarns, complex die installation and the like; on the basis of effectively prolonging the service life of the die, the quality of the steel wire is ensured, the labor intensity of workers is reduced, and the production cost is reduced.
