Description
Technical field
The utility model belongs to rolling of sectional iron apparatus field, is specifically related to a kind of double lead-screw guide and guards.
Background technology
Guide and guards is in rolling of sectional iron process, is arranged on before and after roll pass and helps rolled piece exactly, stably enter by set direction and state and derive the device of roll pass.Existing guide and guards generally moves by the left and right guide plate of Driven by Hydraulic Cylinder the opening degree controlling guide and guards, when required opening degree is transferred to by guide and guards, with hydraulic valve, hydraulic cylinder is locked, thus guide and guards opening degree is fixed, but in long-time rolling process, Chang Yiyin hydraulic leak reason causes hydraulic cylinder can not be locked, and guide and guards opening degree changes, and then when causing steel rolling, percent defective obviously rises.
Utility model content
For above-mentioned defect, the utility model aims to provide the not labile double lead-screw guide and guards of a kind of opening degree.
This double lead-screw guide and guards technical scheme is achieved in that
Described double lead-screw guide and guards, comprise base, left guide plate and right guide plate, left guide plate, right guide plate are symmetrical arranged, be slidably connected on base along base axis direction, described base be also provided with two paranema thick sticks, the screw mandrel in two paranema thick sticks is all arranged along base axis direction, the both ends that two screw mandrels are adjacent are fixedly connected with by shaft coupling, two screw mandrels away from both ends, one is fixedly connected with handwheel, and another is fixedly connected with motor output shaft by shaft coupling;
Screw in two paranema thick sticks, one is fixedly connected with left guide plate, and another is fixedly connected with right guide plate;
The secondary coupling of in two paranema thick sticks has left hand thread, and another secondary coupling has right-handed thread.
Further, described motor is fixed on base by ring flange.
Further, described left guide plate and right guide plate are all provided with deflector roll by bearing holder (housing, cover), deflector roll axis and base axis perpendicular.
Further, described two paranema thick stick pitch are identical, on the base between described left guide plate, right guide plate, apart from left guide plate, right guide plate apart from equal place, along base axis direction is provided with central supporting plate.
Further, side adjacent with central supporting plate on described left guide plate, right guide plate is equipped with side supporting plate, side supporting plate and central supporting plate are to concordant.
Two paranema thick sticks are provided with in double lead-screw guide and guards provided by the utility model, one secondary coupling has left hand thread, another secondary coupling has right-handed thread, screw mandrel in two paranema thick sticks adopts shaft coupling to be fixed with one, this makes it possible to control a left side by rotary screw rod, right guide plate does relatively near motion or relatively away from motion, thus the adjustment achieved guide and guards opening degree, in this double lead-screw guide and guards, the rotation of screw mandrel is mainly through Electric Machine Control, after opening degree is adjusted to the right place, motor stops, left, right guide plate is no longer moved due to the screw thread self-locking function of leading screw, thus ensure that opening degree no longer changes, steel rolling percent defective is obviously reduced, in addition, this double lead-screw guide and guards can also control the adjustment of opening degree by handwheel, increase a kind of regulative mode, adopt double lead-screw structure, when can also avoid selecting single paranema thick stick, the problem that coaxiality error that is that bring is excessive because screw mandrel length is long, is conducive to reducing manufacturing cost simultaneously.

Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Double lead-screw guide and guards provided by the utility model, as shown in Figure 1, comprise base 1, left guide plate 2 and right guide plate 3, left guide plate 2, right guide plate 3 are symmetrical arranged, be slidably connected on base 1 along base 1 axis direction, described base 1 is also provided with two paranema thick sticks, screw mandrel 4 in two paranema thick sticks is all arranged along base 1 axis direction, the both ends that two screw mandrels 4 are adjacent are fixedly connected with by shaft coupling 6, two screw mandrels 4 away from both ends, one is fixedly connected with handwheel 8, and another is fixedly connected with motor 7 output shaft by shaft coupling 6;
Screw in two paranema thick sticks 5, one is fixedly connected with left guide plate 2, and another is fixedly connected with right guide plate 3;
The secondary coupling of in two paranema thick sticks has left hand thread, and another secondary coupling has right-handed thread.
Two paranema thick sticks are provided with in this double lead-screw guide and guards, one secondary coupling has left hand thread, another secondary coupling has right-handed thread, screw mandrel 4 in two paranema thick sticks adopts shaft coupling 6 to be fixed with one, this makes it possible to control a left side by rotary screw rod 4, right guide plate does relatively near motion or relatively away from motion, thus the adjustment achieved guide and guards opening degree, in this double lead-screw guide and guards, the rotation of screw mandrel 4 controls mainly through motor 7, after opening degree is adjusted to the right place, motor 7 stops, left, right guide plate is no longer moved due to the screw thread self-locking function of leading screw, thus ensure that opening degree no longer changes, steel rolling percent defective is obviously reduced, in addition, in this double lead-screw guide and guards, the rotation of screw mandrel 4 can also be controlled by handwheel 8, when needs use handwheel 8 regulates opening degree, needs in advance motor 7 output shaft to be connected disconnection with screw mandrel 4, adopt double lead-screw structure, when can also avoid selecting single paranema thick stick, the problem that coaxiality error that is that bring is excessive because screw mandrel length is long, is conducive to reducing manufacturing cost simultaneously.
Motor 7 in this double lead-screw guide and guards is fixed on base 1 by ring flange 9.
Left guide plate 2 in this double lead-screw guide and guards and right guide plate 3 are all provided with by bearing holder (housing, cover) the deflector roll 11, deflector roll 11 axis and base 1 axis perpendicular that guide rolled piece.
When two paranema thick stick pitch in this double lead-screw guide and guards are identical, left and right guide plate is identical apart from unit centre linear distance, and during rotary screw rod 4, left and right guide plate displacement is identical, and this is conducive to the design difficulty simplifying this double lead-screw guide and guards.
On base 1 between described left guide plate 2, right guide plate 3, apart from left guide plate 2, right guide plate 3 apart from equal place, along base 1 axis direction is provided with central supporting plate 10, side adjacent with central supporting plate 10 on described left guide plate 2, right guide plate 3 is equipped with side supporting plate 12, and side supporting plate 12 and central supporting plate 10 are to concordant.Central authorities' supporting plate 10 and side supporting plate 12 can be played a supporting role to rolled piece.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
