Abstract
The utility model discloses a chain type cold bed which comprises an entry table 1, a driving motor 13, a chain 7, a runout table 10, a driving sprocket 11 and a driven sprocket 12, wherein multiple pairs of steel pipe carrier rollers 5 are uniformly distributed on the chain 7 transversely; and a rolling shaft of each steel pipe carrier roller 5 is connected with two sides of the chain 7. The cold bed can enable a steel pipe to be in a rolling cycling state throughout in a cooling process, so that the steel pipe is uniformly cooled, the automatic straightening capacity is strong, and the straightness is good; and a cold bed system is simple in structure. The chain type cold bed has the advantages of simple structure, scientific and reasonable technology, uniform steel pipe cooling, uniform tissue transformation, and small surface damage, has an automatic straightening capacity and good steel pipe straightness, and guarantees the product quality.
Description
Technical field
The utility model relates to a kind of chain-type cold bed.
Background technology
To go up cold bed behind the seamless steel pipe hot-rolling or after the heat treatment and cool off, require cold bed can guarantee that the steel pipe cooling heat dissipation is good, even, realize the uniformity that interior tissue changes, and good straightness degree, reduce flexibility, reduce the difficulty of following process.Seamless steel pipe such as the 2Cr13 material carries out Quenching Treatment, adopts air-cooled mode, and cooling procedure must guarantee each cross section heat radiation evenly, to realize the uniformity of structural transformation; The big light-wall pipe of length for example is easier to occur bending and deformation again.
At present, the cooling device of seamless steel pipe generally adopts walking beam cooler and chain-type cold bed.The step cooling bed structure is the tooth bar step-by-step movement, steel pipe advances or original position is marked time and realized cooling in the process in rotation, but the rolling distance is short, discontinuous, reduced the uniformity of steel pipe cooling, and cold bed mainly is made up of the cold bed superstructure of cold bed lowering or hoisting gear, cold bed transfer device and stationary rack, mobile rack, complex structure, and equipment cost is higher.The chain-type cold bed mainly is made up of sprocket wheel, chain, motor, and simple in structure, equipment cost is low, but at high temperature, the lubricating condition of chain is more abominable, breaks down easily, and the steel pipe rotation effect of advancing is not very desirable, often translation is carried, even poor cooling performance, and the glacing flatness of steel pipe is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of chain-type cold bed, and this cold bed can make steel pipe be in the state that rolls and circulate all the time in cooling procedure, and the steel pipe cooling is comparatively even, and the automatic flattening ability is strong, good straightness degree, and the cold bed system architecture is simple.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Comprise approach table 1, drive motors 13, chain 7, runout table 10, drive sprocket 11, driven sprocket 12, it is many to steel pipe carrying roller 5 laterally evenly to distribute on chain 7, and the roller bearing of steel pipe carrying roller 5 is connected with chain 7 both sides.
The utility model further improves and is:
The steel pipe carrying roller 5 of chain 7 the first half is supported on the dull and stereotyped roller-way 6.
Dull and stereotyped roller-way 6 is rectangular row, is positioned at steel pipe carrying roller 5 ends.
The beneficial effect that adopts technique scheme to produce is:
It is many to the steel pipe carrying roller laterally evenly to distribute on chain, and the roller bearing of steel pipe carrying roller is connected with the chain both sides, can make under the high temperature, and the light-wall pipe that is easier to occur bending and deformation is supported on steel pipe carrying roller top, to prevent its distortion; The steel pipe carrying roller of chain the first half is supported on the dull and stereotyped roller-way, can make the steel pipe carrying roller in the chain drive process, produce rolling friction with dull and stereotyped roller-way, thereby make the rotation of steel pipe carrying roller, can make steel pipe in cooling procedure, be in the state that rolls and circulate all the time, to reduce crooked tendency.
The utility model is simple in structure, and craft science is reasonable, and the steel pipe cooling is even, and structural transformation is even, and surface damage is little, and has the ability of automatic flattening, and the good straightness degree of steel pipe has ensured product quality.
Description of drawings
Fig. 1 is the front view of the utility model structural representation;
Fig. 2 is the vertical view of the utility model structural representation.
In the accompanying drawings: 1, approach table; 2, revoliving arm; 4, steel pipe; 5, steel pipe carrying roller; 6, dull and stereotyped roller-way; 7, chain; 8, connecting axle; 9, outlet roller-way; 10, runout table; 11, drive sprocket; 12, driven sprocket; 13, drive motors.
The specific embodiment
By the embodiment shown in Fig. 1-2 as can be known, comprise approach table 1, drive motors 13, chain 7, runout table 10, drive sprocket 11, driven sprocket 12, it is many to steel pipe carrying roller 5 laterally evenly to distribute on chain 7, the diameter of steel pipe carrying roller 5 and every pair of steel pipe carrying roller 5 width should be advisable to be fit to placing cooling pipe 4, width between each steel pipe carrying roller 5 should be suitable with the length of revoliving arm 2, to ensure that steel pipe 4 just in time is positioned in every pair of steel pipe carrying roller 5 in transmitting engineering, the roller bearing of steel pipe carrying roller 5 is connected with chain 7 both sides.
The steel pipe carrying roller 5 of chain 7 the first half is supported on the dull and stereotyped roller-way 6.Can make steel pipe carrying roller 5 in chain 7 transmission process, produce rolling friction with dull and stereotyped roller-way 6, thereby make 5 rotations of steel pipe carrying roller.
Dull and stereotyped roller-way 6 is rectangular row, is positioned at steel pipe carrying roller 5 ends.
Operation principle
Its steel pipe cooling procedure is: under the effect of drive motors, steel pipe is delivered in the steel pipe carrying roller through approach table by revoliving arm, the steel pipe carrying roller produces rolling friction with dull and stereotyped roller-way in the chain drive process, thereby make the rotation of steel pipe carrying roller, can make steel pipe in cooling procedure, be in the state that rolls and circulate all the time, to reduce crooked tendency.The utility model is simple in structure, and craft science is reasonable, and the steel pipe cooling is even, and structural transformation is even, and surface damage is little, and has the ability of automatic flattening, and the good straightness degree of steel pipe has ensured product quality.
