Abstract
The utility model provides a kind of two-sided guide groove in built-in slow cooling section that rolls, relate to metallurgical steel rolling field, comprise guide groove body, guide groove body is provided with guide groove bullport, two groups of deflector rolls are also installed in described guide groove body, often organize deflector roll and form by the deflector roll that two are placed in the upper and lower both sides of guide groove bullport respectively, the roll surface of deflector roll is provided with pass, described deflector roll is arranged on guide groove body by eccentric shaft and eccentric bushing, and described deflector roll is arranged on eccentric shaft by duplex bearing.The utility model (the two-sided guide groove in roller slow cooling section) can meet the need of production of plurality of specifications rolled piece, when deflector roll may wear to certain, guide groove body still can continue to use, and only need change deflector roll, extend the service life of guide groove, reduce production cost.
Description
Technical field
The utility model relates to metallurgical steel rolling field, particularly relates to a kind of two-sided guide groove in built-in slow cooling section that rolls.
Background technology
High-speed rod slow cooling section guide groove is the indispensable vitals of rolling line.Guide groove is made up of a set of (rolling line about 50 cover, spread length > 20M) two guide groove bodies, and guide groove plays workpiece motion s more than speed > 65M/S safety, accurately operation effect.
Existing guide barrel construction as Figure 1-3,1: guide groove body.
The defect existed:
1., after rolled piece enters guide groove, run in the state of > 65M/S speed.The motion of rolled piece with jitter motion form objective reality, rubs so inevitably guide hole wall to produce with guide groove and cause product surface to damage (also referred to as pulling).Especially produce the higher product of surface quality requirements, the friction phenomenon in motion can not reach the requirement ensureing surface quality.
2. due to rolled piece shake running status and inevitably guide hole wall to produce friction phenomenon with guide groove, cause the resistance of motion in rolled piece running and produce and pile steel accident.
3. bullport easily produces wearing and tearing because rubbing, and causes entirety to scrap when using after bullport wearing and tearing.
Utility model content
The purpose of this utility model is to provide a kind of two-sided guide groove in built-in slow cooling section that rolls, to solve the problems of the technologies described above.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of two-sided guide groove in built-in slow cooling section that rolls, it is characterized in that: comprise guide groove body, guide groove body is provided with guide groove bullport, two groups of deflector rolls are also installed in described guide groove body, often organize deflector roll to form by the deflector roll that two are placed in the upper and lower both sides of guide groove bullport respectively, the roll surface of deflector roll is provided with pass, and described deflector roll is arranged on guide groove body by eccentric shaft and eccentric bushing, and described deflector roll is arranged on eccentric shaft by duplex bearing.
Described pass is " V " type groove that ring is located on deflector roll roll surface, and the angle of " V " type groove is 120 °, and the bottom land of " V " type groove is arranged to circular arc chamfering.
After rolled piece enters guide groove bullport, under in guide groove, the pass effect of rolling movement and deflector roll done by two deflector rolls, rolled piece is nestled and is run in the pass of deflector roll, overcome the jitter phenomenon in rolled piece running and the resistance of motion, the motion of rolled piece is become easily, steadily, avoids the generation of production accident.Nestle due to rolled piece and run in the pass of deflector roll, avoid rolled piece and guide groove to guide hole wall to produce and rub, thus the surface damage avoiding product to cause because of friction.
The beneficial effects of the utility model are:
The utility model (the two-sided guide groove in roller slow cooling section) can meet the need of production of plurality of specifications rolled piece, when deflector roll may wear to certain, guide groove body still can continue to use, and only need change deflector roll, extend the service life of guide groove, reduce production cost.

Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with specific embodiments and the drawings, further elaboration the utility model, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in embodiment, those skilled in the art under the prerequisite not making creative work obtain other embodiment, all belong to protection scope of the present invention.
As Figure 4-Figure 6, a kind of two-sided guide groove in built-in slow cooling section that rolls, comprise guide groove body 1, guide groove body 1 is provided with guide groove bullport 8, two groups of deflector rolls 2 are also installed in guide groove body 1, often organize deflector roll 2 and form by the deflector roll that two are placed in guide groove bullport about 8 both sides respectively, the roll surface of deflector roll 2 is provided with pass 9, deflector roll 2 is arranged on guide groove body 1 by eccentric shaft 3 and eccentric bushing 5, and deflector roll 2 is arranged on eccentric shaft 3 by duplex bearing 4.
Spacing between two deflector rolls of the upper and lower both sides of guide groove bullport, can according to rolled piece specification and actual needs adjustment.Set-up procedure is: unclamp locking nut 6 and fastening bolt 7, according to rolled piece specification and actual needs eccentric rotation axis 3, until tighten locking nut 6 and fastening bolt 7 after reaching requirement again; When using guide groove B face different size pilot hole, eccentric shaft 3 can be rotated the adjustment that some angles carry out deflector roll spacing.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description is only preference of the present utility model; be not used for limiting the utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
