Description

Section straightener

The utility model relate to a kind of under cold state the section straightener to correcting such as steel such as I-steel, angle steel, channel-section steel, square steel, round steel and deformed steels.

At present, be used for the straightener corrected such as shaped steel such as I-steel, angle steel, channel-section steel, square steel, round steel and deformed steels in the steel rolling industry, its initiative roll shaft and passive roll shaft all are to be evenly equidistant to be provided with.Though this straightener also can be corrected shaped steel, because its roll shaft is equidistant setting, it is low not only to correct precision, and the scope of application is wideless.

The purpose of this utility model is to provide a kind of precision height, section straightener applied widely corrected.

Section straightener of the present utility model comprises motor, deceleration device and rectangle frame, and both sides, frame upper end have some gap that are used to install passive roll shaft, has two row circular holes below the gap, initiative roll shaft is installed and the axle of passing a bridge in it respectively.One end main, passive roll shaft stretches out outside the rectangle frame, and running roller all is installed on this external part.On the initiative roll shaft and the axle of passing a bridge driving gear and carrier gear are arranged respectively.The rotating shaft of motor is connected mutually with the high speed gear shaft of deceleration device.The low-speed gear axle overhanging end of deceleration device is equipped with gear, and carrier gear is meshed with this gear and driving gear respectively.Also be equipped with above the bearing block of the passive roll shaft of rectangle frame both sides and can make the upper and lower mobile governor motion of passive roll shaft.Its design feature is between each initiative roll shaft, between each passive roll shaft and each is passed a bridge all not to be between the axle and equidistantly is provided with, and feed end to the distance between every adjacent two roll shafts of discharge end by diminishing greatly gradually.

Because between the initiative roll shaft of the present utility model, between the passive roll shaft and pass a bridge all to be between the axle and equidistantly be provided with, and roll spacing from feed end to discharge end by diminishing greatly gradually, rectification precision height, applied widely.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is a section straightener schematic diagram of the present utility model;

Fig. 2 is the A-A partial schematic sectional view of Fig. 1;

Fig. 3 is the B-B revolved section schematic diagram of Fig. 1;

Fig. 4 is that schematic diagram is looked on the left side of Fig. 1.

See Fig. 1 and Fig. 3, section straightener of the present utility model comprises motor 10, deceleration device and rectangle frame 28.Rectangle frame wherein comprises shell 31, and high speed gear shaft 13, gear shaft 17 and low-speed gear axle 18 are installed in this shell side by side.The rotating shaft 11 of motor 10 links to each other with an end of high speed gear shaft 13 by key 12, and the other end of this high speed gear shaft is installed on shell 31 sidewalls of deceleration device by means of bearing block, also is fixed with high gear 14 on the high speed gear shaft 13.The two ends of gear shaft 15 also are installed on shell 31 two sides of deceleration device by bearing block, and gear shaft 15 parallels with high speed gear shaft 13, and gear 16,17 is installed on the gear shaft 15.Gear 16 wherein is meshed with high gear 14 on the high speed gear shaft 13, and gear 17 is meshed with gear 19 on the low-speed gear axle 18.One end of low-speed gear axle 18 is installed on shell 31 sidewalls of deceleration device, and another sidewall that the other end then passes deceleration device shell 31 is installed on the sidewall of rectangle frame 28.Have some U font gap on the two side, upper end of rectangle frame 28, below this gap along laterally having two row circular holes.The two ends of several passive roll shafts 21, initiative roll shaft 22 and the axle 24 of passing a bridge are installed in U font gap and the row of two under it circular hole by bearing block successively.See Fig. 4, passive roll shaft 21 and initiative roll shaft 22 do not stretch out outside the rectangle frame 28 by an end of motor 10, and this overhanging end is equipped with running roller 26.By being fixed with gear 20, driving gear 23 and carrier gear 25 respectively on the low speed roll shaft 18 in the rectangle frame 28 of motor 10 1 sides, initiative roll shaft 22 and the axle 24 of passing a bridge, carrier gear 25 is not meshed with gear 20 and driving gear 23 respectively.Passive roll shaft 21, initiative roll shaft 22 and the axle 24 of passing a bridge are not each other separately and equidistantly are provided with, its mutual separately distance from feed end to discharge end by diminishing greatly gradually, so that the raising machining accuracy.See Fig. 2, be provided with on the bearing block of the passive roll shaft 21 of rectangle frame 28 both sides and can make the upper and lower mobile governor motion of passive roll shaft, this governor motion comprises an elevating screw 1, the lower end of elevating screw is fixed by bolts on the bearing block of passive roll shaft 21, and its upper end has been screwed and transferred crack nut 2 and round nut 3.Adjusting nut 6 has been screwed in the stage casing of elevating screw 1, and a worm gear 4 is fixed with key in the outside of this adjusting nut, and the two ends of the worm screw 5 that cooperates with worm gear 4 are installed on the shell 32 of governor motion by bearing block, and the one end also is equipped with handwheel 29.Rotate handwheel 29 worm screw 5 is rotated, and drive worm gear 4 and adjusting nut 6 rotations, do upper and lower moving thereby make elevating screw 1 drive passive roll shaft 21.

When straightener of the present utility model is worked, at first drive the high speed gear shaft 13 and the high gear 14 that are fixed with one with it and rotate by motor 10.Because the gear 16 on gear 14 and the gear shaft 15 is meshed, the gear 17 on the gear shaft 15 is meshed with gear 19 on the low-speed gear axle 18 again, when gear 14 rotates, can rotate by gear 16,17 driven gears 19 again.Again since gear 20 be meshed with a gear 25 of passing a bridge on spools 24, gear 25 is meshed with gear 23 on the initiative roll shaft 22 again, when gear 20 rotates, can rotate by gear 25 and gear 23 again, rotate thereby drive the running roller 26 that is installed in initiative roll shaft 22 outer ends.Because running roller 26 and the running roller 26 on the passive roll shaft 21 on the initiative roll shaft 22 will be clipped in the middle by strong workpiece tightly, when initiative roll shaft 22 drives running roller 26 on it and rotates, the running roller 26 that relies on friction to drive on the passive roll shaft 21 rotates, thereby make by strong workpiece motion s, realize rectification workpiece.

The initiative roll shaft 22 of section straightener of the present utility model, passive roll shaft 21 and the axle 24 of passing a bridge can be installed on the rectangle frame 28 by rolling bearing, so that effectively control is main, the circular runout and the axial float of

passive roll shaft

22,21, improve flattening precision and complete machine service life.

See Fig. 1, a blind hole can be bored in the U font gap bottom of the upper end, rectangle frame 28 both sides of section straightener of the present utility model, equipped spring 27 in it, the upper end of this spring is withstood the bearing block bottom of passive roll shaft 21 tightly, make passive roll shaft 21 keep balance, when charging and discharging the moment impact phenomenon can not appear, but prolonged mechanical service life.

See Fig. 2, a nut 8 can be fixed in bearing holder (housing, cover) 7 outsides of the initiative roll shaft 22 of section straightener of the present utility model and passive roll shaft 21 uneasy running roller 26 1 ends, be fitted with the screw rod 9 that is coupled as one with handwheel 30 in this nut, so that initiative roll shaft 22 and passive roll shaft 21 are carried out axial adjustment.

The described deceleration device of the above-mentioned arbitrary embodiment of the utility model can be arranged near in the rectangle frame 28 of motor 10 1 sides, so that itself and complete machine form as one.Not only compact conformation, floor space are few, also can reduce power consumption, reduce production costs.
