Abstract
The utility model relates to a rail preflex device, including base, a supporting beam, dolly and motor, a supporting beam is installed on the base, is equipped with the slip track on a supporting beam, and the motor is connected with the slip track, and the dolly is installed on the slip track top, and the dolly includes supporting seat and movable fixture, and movable fixture installs on the supporting seat top. The utility model has the advantages of reasonable design, convenient operation prevents that the rail from being scratched when the preflex, can extensively be used for steel production field.
Description
Technical field
The utility model relates to a kind of iron and steel processing unit (plant), particularly relates to a kind of rail pre-bending device.
Background technology
Need cool off at step cooling bed after the rail hot-roll forming, because temperature drop speed is inconsistent, section is asymmetric, so rail cooling back produces usually crooked in cooling procedure.And, to keep certain glacing flatness after the rail cooling to guarantee the conveying and the aligning of rail according to technological requirement.Therefore need before cooling, carry out pre-bending,, reach certain glacing flatness after making the rail cooling, be convenient to carry and aligning to offset the bending that it produces in cooling procedure to rail.The clamp distance broad of anchor clamps on the present rail pre-bending device, in the pre-bending process, rail is meeting left and right sides play on anchor clamps, has influenced the effect of rail pre-bending, if shorten the clamp distance of anchor clamps, rail can bump and the scratch surface when entering anchor clamps.In sum, present pre-bending device can't reach good pre-bending effect.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, and is easy to operate, the rail pre-bending device that pre-bending is effective.
In order to address the above problem, the utility model by the following technical solutions:
A kind of rail pre-bending device comprises base, brace summer, dolly and motor, and brace summer is installed on the base, brace summer is provided with sliding rail, and motor is connected with sliding rail, and dolly is installed in the sliding rail top, dolly comprises supporting seat and floating holder, and floating holder is installed in the supporting seat top.
Described supporting seat middle part is provided with slideway, and place, slideway bottom surface is provided with cylindrical groove, and the floating holder bottom is provided with rotating shaft, and the rotating shaft of floating holder is inserted in the cylindrical groove of supporting seat.
Described slideway both sides are provided with spring, and spring one end is fixed on the slideway sidewall, and an end is against on the floating holder of dolly.
Compared with prior art, the beneficial effects of the utility model are:
The anchor clamps on the utility model pre-bending device top can rotate around fixed axis, cooperate the impulse force that is used for cushioning rail of spring, prevent the rail scratch that bumps in traveling process, have guaranteed rail pre-bending effect to greatest extent.
