Abstract
The utility model relates to a steel straightener machine, in particular to a sectional steel straightener with axial adjustment. A straightener shaft of this machine is installed on one side board of a cabinet by four-row cylindrical roller bearings, an inner bearings sleeve and an outer bearings sleeve; the inner bearings sleeve is longer than the outer bearings sleeve by 40-50 cm, and one end of the inner bearings sleeve is provided with a bearing baffle fixed with it; both sides of the bearing baffle are provided with a reel of thrust ball bearings; outside parts of the thrust ball bearings are sheathed with a sliding bearing sleeve; the sliding bearing sleeve is sheathed with a coat fixed with the side board of the cabinet outside; the coat is provided with a feed screw nut mechanism linking with the sliding bearing sleeve. The utility model can realize axial adjustment in stopped status; compared with prior straighteners, the utility model has advantages of saving factory expense, reducing production cost, improving durability and convenience for operating as well as maintenance.
Description
Technical field:
The utility model relates to requisite section straightener tool in the steel rolling process, but a kind of section straightener of axial adjustment particularly.
Background technology:
Realization is to the aligning of rolled steel, must realize the upper and lower and axial adjusting of straightening shaft, the leading screw screw is adopted in upper and lower adjusting, and axial adjustment has two kinds of methods at present: one, straightening shaft is motionless, draws realization to move axially the smoothing roll that is contained on the axle with the screw pressure, because there is the gap in smoothing roll with axle, therefore stressed bad, and this method is unadjustable under open state; They are two years old, with the bearing holder (housing, cover) of packing into of the bearing on the straightening shaft, bearing holder (housing, cover) axially moves in casing (or slide) hole, thereby realization axial adjustment, this method has strengthened the size in casing (or slide) hole, correspondingly also strengthened the size of slide, make downward regulated quantity be restricted, shortened the service life of smoothing roll, maintenance is also inconvenient, simultaneously because there are the gap in bearing holder (housing, cover) and box body hole, therefore the transmission accuracy that is contained between the gear on the straightening shaft is affected, and because the wearing and tearing of bearing holder (housing, cover), gear centre will be apart from dwindling gradually, and this will bring fatal infringement to travelling gear.
Summary of the invention:
Goal of the invention of the present utility model is intended to separate the axial adjustment that can realize under the stopped status never straightening shaft; and can solve install that axle sleeve brings oversize such as box body hole, upper saddle is oversize, downward regulated quantity reduces relatively; and problems such as gear-driven accuracy is poor, centre-to-centre spacing size decreases, but and provide a kind of and both saved manufacturing expense, reduce production costs, improve durability, be convenient to the section straightener of the axial adjustment of operating and keeping in repair.
The technical scheme that realizes the foregoing invention purpose is: this section straightener comprises cabinet, straightening shaft, parts such as smoothing roll, this straightening shaft is by four-line column roller bearing and bearing inner sleeve thereof, bearing outside is installed on this cabinet side board, this bearing inner sleeve is longer than this bearing outside 40-50cm, be equipped with and its fixing bearing baffle the end of this straightening shaft, these bearing baffle both sides are equipped with a dish thrust ball bearing respectively, this thrust ball bearing outer cover is equipped with sliding bearing sleeve, this sliding bearing sleeve outer cover is equipped with and the fixing overcoat of cabinet side board, and the leading screw screw mechanism with this sliding bearing sleeve interlock is housed in this overcoat.
But the section straightener of the axial adjustment that realizes according to technique scheme, adopt the four-line column roller bearing of cover in the lengthening, the sound load of bearing is big, and radial load is greater than other bearing, and straightening shaft is in suffered axial force of when work, and then the leading screw screw mechanism by the other end bears.Because the accuracy of manufacture of bearing own is higher, thereby makes that the straightening shaft circular runout is very little, and axial adjustment is very light, and because the durability of bearing itself is higher, thereby make the service life of this straightener and maintenance cycle prolong greatly.So this straightener not only has higher mechanical properties compared with the prior art, also has the higher economical efficiency energy.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.
But the section straightener of the described axial adjustment of present embodiment is by straightening shaft 1, smoothing roll 2, bearing outside 3, bearing inner sleeve 4, cylinder roller bearing 5, cabinet side board 6, travelling gear 7, bearing baffle 8, thrust ball bearing 9, sliding bearing sleeve 10, screw 11, leading screw 12, overcoat 13, positioning sleeve 14, handwheel 15, locknut 16 parts such as grade are formed, this straightening shaft 1 is by four-line column roller bearing 5 and bearing inner sleeve 4 thereof, bearing outside 3 is installed on this cabinet side board 6, this bearing inner sleeve 4 is than this bearing outside 3 long 40-50cm, to satisfy the axial adjustment amount of this straightening shaft 1; These straightening shaft 1 one ends are equipped with smoothing roll 2, the other end is equipped with and its fixing bearing baffle 8, these bearing baffle 8 both sides are equipped with a dish thrust ball bearing 9 respectively, these thrust ball bearing 9 outer cover are equipped with sliding bearing sleeve 10, these sliding bearing sleeve 10 outer cover are equipped with the overcoat of fixing with cabinet side board 6 13, and the leading screw screw mechanism with 10 interlocks of this sliding bearing sleeve is housed in this overcoat 13.Handwheel 15 is equipped with in outer 12 ends of the leading screw of described this leading screw screw mechanism of present embodiment, is provided with positioning sleeve 14 between this handwheel 15 and this overcoat 13, connects firmly between this screw 11 and this sliding bearing sleeve 10.
As shown in the figure, pulling handwheel 15, the leading screw 12 that links with it will spur screw 11 and sliding bearing sleeve 10, because two dish thrust ball bearings 9 are housed in this sliding bearing sleeve 10, so this bearing baffle 8 that thrust ball bearing 9 just promotes and straightening shaft 1 connects firmly, straightening shaft 1 just can produce and move axially.Handwheel 15 is by up time or rotate counterclockwise, and 1 of straightening shaft produces move left and right, thereby finishes the axial adjustment action, regulate finish after, with bolt and positioning sleeve 14 locking handwheels 15.
Claims (2)
1, but a kind of section straightener of axial adjustment, comprise cabinet, straightening shaft, smoothing roll, it is characterized in that this straightening shaft is by four-line column roller bearing and bearing inner sleeve thereof, bearing outside is installed on this cabinet side board, this bearing inner sleeve is longer than this bearing outside 40-50cm, be equipped with and its fixing bearing baffle the end of this straightening shaft, these bearing baffle both sides are equipped with a dish thrust ball bearing respectively, this thrust ball bearing outer cover is equipped with sliding bearing sleeve, this sliding bearing sleeve outer cover is equipped with and the fixing overcoat of cabinet side board, and the leading screw screw mechanism with this sliding bearing sleeve interlock is housed in this overcoat.
But 2, the section straightener of axial adjustment according to claim 1 is characterized in that handwheel is equipped with in the leading screw outer end of this leading screw screw mechanism, is provided with positioning sleeve between this handwheel and this overcoat, connects firmly between this screw and this sliding bearing sleeve.
