Abstract
The utility model provides an improved idler roller device of an edging mill and relates to the field of rolling mill equipment technology. The utility model is aimed at solving the problem of frequent breakage of gland bolts on the two sides of an idler roller and prolonging the service lifetime of the idler roller. The improved idler roller device comprises a roller, a roller sleeve, a shaft, bearings on the two sides and glands on the two sides. Side gland bolt holes on the two sides of the idler roller sleeve are through holes penetrating the roller sleeve along the axial direction of the roller sleeve; a plurality of side gland bolt holes are distributed uniformly along the circumference of the roller sleeve; and side gland fixing bolts are long bolts penetrating the through holes. The through holes penetrating the roller sleeve along the axial direction of the sleeve roller serve as the side gland bolt holes, the long bolts penetrating the side gland bolt holes are used for fixation, and the diameters of the side gland bolt holes and the side gland fixing bolts are increased, so that the strength of the side gland fixing bolts are improved, the problem of idler roller damage caused by loosening of side gland fixing bolts of the idler roller can be effectively solved, and the service lifetime of the idler roller is prolonged from original three months to more than one year.
Description
Technical field
The utility model relates to a kind of idler roller device of vertical miller, belongs to the milling equipment technical field.
Background technology
In steel plate rolling was produced, vertical miller mainly was the width of controlled rolling steel plate.The edger roll memorial archway is the part in the vertical miller, and a cover idler roller device is arranged between two memorial archways of edger roll, mainly is just to carry at rolling steel plate, makes steel plate that individual transition be arranged.The idler roller roller mainly is comprised of roller, roller shell, axle, two side bearings, both sides gland.Because steel plate is to the enormous impact of idler roller, the gland bolt of idler roller roller shell both sides often ruptures, and the both sides gland is altered outward, and the bearing water inlet causes that roller is stuck not to be turned, and causes the idler roller life cycle shorter, generally maintains about three months.Change idler roller and not only delayed normally carrying out of producing, increased maintenance time, reduced productivity effect, also improved cost, therefore be necessary existing equipment is improved.
The utility model content
Technical problem to be solved in the utility model provides a kind of improved vertical miller idler roller device that can solve the frequent breakage problem of idler roller both sides gland bolt, prolongation idler roller life cycle.
The technical scheme that solves the problems of the technologies described above is:
A kind of improved vertical miller idler roller device, it is comprised of roller, roller shell, axle, two side bearings, both sides gland, its improvements are, the side pressure bonnet bolt hole of idler roller roller shell both sides is for axially running through the through hole of roller shell along roller shell, a plurality of side pressure bonnet bolts hole is along the roller shell circumference uniform distribution, and side pressure lid set bolt is the stay bolt that runs through through hole.
Above-mentioned improved vertical miller idler roller device, described side pressure bonnet bolt hole is the through hole of M20, side pressure lid set bolt is interior six square bolts of M20*300.
The beneficial effects of the utility model are:
The utility model adopts and axially runs through the through hole of roller shell as side pressure bonnet bolt hole along roller shell, use simultaneously the stay bolt that runs through side pressure bonnet bolt hole to be fixed, the enlarged diameter of side pressure bonnet bolt hole and side pressure lid set bolt, these improvement have improved the intensity of side pressure lid set bolt, can effectively solve the loosening idler roller that causes of idler roller side pressure lid set bolt and damage, the life cycle of idler roller extended to more than 1 year by original 3 months.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the structural representation of prior art idler roller roller shell;
Fig. 4 is the side view of Fig. 3.
Number in the figure is as follows: roller shell 1, side pressure bonnet bolt hole 2.
The specific embodiment
Show among the figure, the utility model is comprised of roller, roller shell 1, axle, two side bearings, both sides gland.At these
In the structure, the utility model improves side pressure bonnet bolt hole 2 and the side pressure lid set bolt of roller shell.
Show among the figure, side pressure bonnet bolt of the prior art hole 2 is along roller shell 1 circumference uniform distribution, and side pressure bonnet bolt hole 2 is to the inside arranged respectively in roller shell 1 both sides, the length that side pressure bonnet bolt hole 2 is certain.Such structure, under the enormous impact of steel plate to idler roller, the side pressure bonnet bolt of both sides often ruptures, the generation that causes the accident.
Show among the figure, improvements of the present utility model are: change the side pressure bonnet bolt hole 2 of idler roller roller shell 1 both sides into axially run through roller shell along roller shell 1 through hole, a plurality of side pressure bonnet bolts hole 2 is along roller shell 1 circumference uniform distribution, and side pressure lid set bolt is the stay bolt that runs through through hole.
Above-mentioned improved side pressure bonnet bolt hole 2 is the through hole of M20, and side pressure lid set bolt is interior six square bolts of M20*300.
After improving, the enlarged diameter of side pressure bonnet bolt hole 2 and side pressure lid set bolt, improved the intensity of side pressure lid set bolt, can effectively solve the loosening idler roller that causes of idler roller side pressure lid set bolt and damage, the life cycle of idler roller extended to more than 1 year by original 3 months.
