Description

Rolling mill guide base device

Technical Field

The utility model relates to the technical field of metal smelting, in particular to the technical field of rolling mill design, and particularly relates to a rolling mill guide base device.

Background

Rolling mill guides are devices for controlling the entry or exit of the rolled stock into or out of the rolls and are typically made of cast iron. The guide keeps the rolled piece in the correct direction when entering and exiting the roll, thereby ensuring the yield and quality of the product. As shown in fig. 1, when the guide base of the conventional rolling mill is adjusted to move left and right in the process of replacing the rolling groove or in the normal production process, the center line of the guide and the rolling center line should be on the same straight line and perpendicular to the moving direction. However, when the rolling mill is used for a long time, the guide base is greatly abraded after long-time use. The abrasion can cause the deviation of the center line of the guide and the rolling center line of the rolling groove to form a certain angle, so that the material type control of a rolled piece is unstable, and the phenomena of secondary products, even steel holding and the like can occur.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is as follows: in order to overcome the defects of the prior art, the utility model provides the rolling mill guide base device which effectively reduces the phenomenon that the rolling center lines are not aligned due to guide play, reduces steel holding faults, effectively ensures the production stability and improves the product quality.

The technical scheme adopted by the utility model for solving the technical problems is as follows: a rolling mill guide base device is arranged on a rolling mill and comprises a guide beam and a guide base, wherein the central line of the guide beam is superposed with the rolling central line of the rolling mill, a long key is fixed on the contact surface of the guide beam and the guide base, which is perpendicular to the central line of the guide beam, the central line of the long key in the length direction is perpendicular to the central line of the guide beam, the central line of the long key in the width direction is superposed with the central line of the guide beam, a key groove is fixed on the guide base, and the key groove is matched and connected with the long key and moves along the length direction of the long key.

In the scheme, the guide base is ingeniously matched with the long key through the key groove, the direction of displacement adjustment of the guide base is limited, and the phenomenon that rolling center lines are not aligned due to the fact that the guide base is moved is effectively avoided.

Preferably, the section of the long key along the central line of the guide beam is isosceles trapezoid, and the key groove is a groove shape which is matched with the shape of the long key and is in the shape of the isosceles trapezoid.

The long key can be fixed with the guide beam through a bolt, so that the existing rolling mill is convenient to reform, and the long key is fixedly connected with the guide beam through an inner hexagon bolt.

The rolling mill guide base device has the advantages that the structure is reasonable, the isosceles trapezoid key groove is formed in the guide base, and the isosceles trapezoid key groove is matched with the isosceles trapezoid long key, so that the direction positioning can be effectively provided for the guide when the guide base moves left and right, the center line of the guide can be still correspondingly overlapped with the rolling center line after moving, the phenomenon that the rolling center lines are not aligned due to sliding of the guide is avoided, steel holding faults are reduced, the production stability is effectively guaranteed, and the product quality is improved.

Drawings

The utility model is further illustrated with reference to the following figures and examples.

Fig. 1 is a schematic view of the guide base and the guide beam of a conventional rolling mill being moved together (the direction of the arrow is the moving direction of the guide base).

Fig. 2 is a schematic structural diagram of the preferred embodiment of the present invention (the direction of the arrow is the moving direction of the guide base).

In the figure 1, a guide base 2, a guide beam 3, a long key 4, a key groove 5 and an inner hexagon nut.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

The rolling mill guide base 1 device shown in fig. 2 is the preferred embodiment of the utility model, the guide base 1 device is arranged on a rolling mill, and the rolling mill comprises a guide beam 2 and a guide base 1. The central line of the guide beam 2 coincides with the rolling central line of the rolling mill, and a long key 3 is fixed on the contact surface of the guide beam 2 and the guide base 1 and is vertical to the central line of the guide beam 2. The long key 3 is fixedly connected with the guide beam 2 through an inner hexagon bolt 5. The bolt is fixedly connected, so that the existing rolling mill can be conveniently transformed, or the rolling mill can be conveniently and quickly maintained and replaced after being used and worn for a long time.

The center line of the long key 3 in the length direction is vertical to the center line of the guide beam 2, and the center line of the long key in the width direction is superposed with the center line of the guide beam 2. The guide and guard base 1 is fixed with a key slot 4, and the key slot 4 is connected with the long key 3 in a matching way and moves along the length direction of the long key 3. The long key 3 is isosceles trapezoid along the center line section of the guide beam 2, and the key groove 4 is a groove shape of isosceles trapezoid shape matched with the long key 3 in shape.

The rolling mill of such design leads and defends base device, the structure sets up rationally, through leading and defending 1 and go up isosceles trapezoid's keyway 4 of design, and through isosceles trapezoid keyway 4 and isosceles trapezoid long key 3's cooperation, can effectively guide and defend and provide the direction location for leading when controlling about base 1, guarantee to lead and defend the central line and still can correspond the coincidence with rolling central line after removing, avoid leading and defend the phenomenon that the rolling central line that leads to aligns inadequately, reduce the steel fault of suffocating, effectively guarantee production stability and improve product quality.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
