Description

The steel pipe cold bed

Technical field

The utility model relates to metallurgy industry steel pipe's production equipment, particularly a kind of steel pipe cold bed equipment that is used for the steel pipe cooling.

Background technology

On the steel pipe rolling production line and heat-treatment lines of smelter, in order to obtain the desirable mechanical performance of steel pipe, on production line, need to be equipped with cold bed equipment, make steel pipe on cold bed, be transmitted and cool off.Because steel pipe is a hollow section, for mechanical performance and the geometry that guarantees steel pipe, need cold bed evenly cooling pipe have the function of thermal straightening again, just cold bed is in cooling transmission steel pipe, can also make steel pipe ceaselessly around the axis rotation of himself, could guarantee mechanical performance and geometry when steel pipe cools off like this.

The actual at present steel pipe cold bed that uses mainly is double-chain cold bed and walking beam cooler.

Double-chain cold bed comprises band chain and carrier chain, and the traffic direction of band chain and carrier chain is opposite, and carrier chain promotes steel pipe and travels forward, and band chain drives steel pipe and rotates.This double-chain cold bed is because employing two cover chains, two overlap transmission devices, so complex structure, and the equipment funds input is bigger; And, be not easy to aborning safeguard because of its complex structure.

Walking beam cooler is by one group of static rack, one group of carry-over bar is formed with the driving adjusting device, carry-over bar rotates along with two cam disks and makes (replacing) rectangular path and move, each period of motion steel pipe always raises along quiet tooth rolling stretch journey with carry-over bar earlier and changes certain angle, then the passive tooth bar of steel pipe lifts and crosses the translation forward of quiet tooth tooth top, then, servo-actuated tooth decline steel pipe is again along static rack rolling stretch journey and change certain angle, moving at last tooth is retracted original position from the steel pipe lower plane, and the bending that steel pipe produces in process of production is also because high-temperature steel tube keeps flat on the cold bed tooth bar beam because of rolling around himself axis aligns gradually.But this steel pipe cold bed exists equally, and the equipment funds input is many, complex structure, the shortcoming of easy care not.

The utility model content

In order to overcome the weak point that above-mentioned prior art exists, task of the present utility model provides a kind of novel steel pipe cold bed, and it has solved existing steel pipe cold bed complex structure, equipment funds and has had high input, is not easy to aborning the problem safeguarded.

Technical solution of the present utility model is as follows:

A kind of steel pipe cold bed, it comprises lathe bed, drive unit, the chain of sprocket wheel and conveying and rotation steel pipe;

Described sprocket wheel has drive sprocket and by movable sprocket, drive sprocket and be placed in lathe bed two ends respectively by movable sprocket, and drive sprocket is connected with drive unit;

Described chain is made up of several chain rivets, carrier bar, support wheel and road wheel, two ends at each chain rivet are installed road wheel, support wheel is installed in the middle of each chain rivet, carrier bar is installed in two sides of support wheel and interlinks, form a chain thus, several chains are arranged in parallel by spacing, form a cold bed;

Road wheel on the described chain when operation respectively with drive sprocket with by the gear teeth meshing of movable sprocket, road wheel on each chain rolls with its residing chain bracket and bottom bracket and contacts, chain rivet on the chain, support wheel and road wheel are formed a rotary unit, form per two support wheels thus and support a steel pipe.

Adopt steel pipe cold bed of the present utility model, be cooled in making steel pipe on cold bed, rotate to advance, guarantee the mechanical performance and the geometry of steel pipe.This steel pipe cold bed is simple in structure, and cost of investment is low, is easy to safeguard.

The specific embodiment

Referring to Fig. 1 and Fig. 2, a kind of steel pipe cold bed of the present utility model comprises the chain 2 of lathe bed 5, drive unit 7, sprocket wheel and conveying and rotation steel pipe.

Sprocket wheel has drive sprocket 6 and by movable sprocket 1, drive sprocket 6 and be placed in lathe bed 5 two ends respectively by movable sprocket 1, and drive sprocket 6 is connected with drive unit 7.

Referring to Fig. 3 and Fig. 4, chain 2 is made up of several chain rivets 10, carrier bar 11, support wheel 8 and road wheel 9.Two ends at each chain rivet 10 are installed road wheel 9, and 8, four carrier bars 11 of installation support wheel are installed in two sides of support wheel 8 and interlink in the middle of each chain rivet 10.Each chain rivet 10 is bound up carrier bar 11, support wheel 8, road wheel 9, forms a chain 2 thus.Several chains 2 are arranged in parallel at a certain distance, form a cold bed.

Respectively with the drive sprocket 6 that is positioned at cold bed two ends with by the gear teeth meshing of movable sprocket 1, the pilled-in selvedge on each chain 2 and the road wheel 9 of slack list roll with its residing chain bracket 3 and bottom bracket 4 and contact road wheel 9 on the chain 2 when operation.Chain rivet 10 on the chain 2, support wheel 8 and road wheel 9 are formed a rotary unit, form per two support wheels 8 thus and support a steel pipe 12.

When cold bed was worked, checkout gear detected steel pipe supplied materials situation, during supplied materials, two support wheels 8 arrive and treat material level, and cold bed stops operating, and by take out device the supplied materials steel pipe is placed on two support wheels 8, get material and finish, drive unit 7 drives drive sprocket 6 rotations, thereby drives chain 2 walkings.Road wheel 9 rotates under the promotion of chain 2 and advances, thereby support wheel 8 is rotated together, be placed on two steel pipes 12 on the support wheel 8 and also be driven to rotate and advance, and then make steel pipe 12 in rotation is advanced, be cooled, guaranteed the mechanical performance and the geometry of steel pipe.When steel pipe 12 arrival cold bed ends, steel pipe 12 is by the blanking device blanking.

Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
