Background
The short stress line rolling mill has the characteristics of high rigidity, high product precision, light equipment weight, simple operation and particularly quick online replacement of the rolling mill, so that the short stress line rolling mill becomes a leading model in the rolling operation of the present domestic rod and wire factories.
In the rolling process, the rolling force of the rolling mill is formed into a closed loop line, namely a stress line, through the internal stress of each stress component such as a roller, a roller bearing, a box body, a pull rod and the like, wherein the elastic deformation of the stress component is in direct proportion to the length of the stress line, so that the length of a stress loop is shortened, the elastic deformation of the rolling mill can be reduced, and the strength of the rolling mill is improved, and the rolling mill is called a short stress line rolling mill.
With the increase of the service life of the rolling mill, each stress part of the rolling mill can be worn to different degrees under the condition of the rolling mill body, and the matching precision of each stress part can be greatly reduced. At the moment of biting of the red steel, the rolling mill is often subjected to very large impact, so that the height of a roller bearing seat on the rolling mill is reduced, the center line of a roll pass is lower than the center line of the rolling mill, and finally the rolling mill is sunk.
Disclosure of utility model
The utility model aims to provide a roller bearing box supporting device of a short stress line rolling mill, which can avoid that the center line of a roller pass is lower than the center line of rolling caused by the reduction of the height of a roller bearing seat on the short stress line rolling mill, and solve the problems in the prior art.
The technical scheme of the utility model is as follows:
The utility model provides a short stress path rolling mill roll bearing box strutting arrangement, include upper roller bearing box, lower roller bearing box, the pull rod, supporting mechanism, pull rod copper sheathing, pull rod shoulder, push nut and rolling mill frame, the pull rod sets up between upper roller bearing box and lower roller bearing box, be fixed with the push nut respectively on upper roller bearing box and the lower roller bearing box, the both ends of pull rod are connected respectively on the push nut, the centre of pull rod is equipped with the pull rod shoulder, be equipped with the pull rod copper sheathing on the pull rod shoulder, the pull rod copper sheathing is fixed in rolling mill frame; the supporting mechanism is arranged between the upper roller bearing box and the pull rod copper sleeve and comprises a supporting seat, an adjusting bolt and a supporting sleeve, wherein the supporting seat is fixed on the rolling mill stand, the adjusting bolt is fixed on the supporting seat, the supporting sleeve is in threaded connection with the adjusting bolt, and the supporting sleeve is supported on the upper roller bearing box.
And a groove matched with the head part of the adjusting bolt is arranged on the supporting seat in the supporting mechanism.
The support sleeve in the support mechanism is provided with internal threads matched with the adjusting bolt.
The pull rod copper sleeve is fixed on the pull rod shaft shoulder through a fixing screw.
External threads matched with the pressing nuts are respectively arranged at two ends of the pull rod.
The beneficial effects of the utility model are as follows: the roller pass center line is lower than the rolling center line due to the reduction of the height of the upper roller bearing seat of the short stress line rolling mill, and the normal operation of steel rolling production is ensured through the pull rod between the upper roller bearing box and the lower roller bearing box and the supporting mechanism between the upper roller bearing box and the pull rod copper sleeve.
