Description

Technical Field

[0001] The utility model belongs to the technical field of supporting facilities of rolling mills, and particularly relates to an outlet guide used in the production of plate and strip rolled steel and convenient for handling piled steel. Background Art

[0002] The exit of the finishing mill is now equipped with an integrated hydraulic guide, which has the advantage of hydraulically controlling the extension or withdrawal of the guide, thereby improving the degree of automation and efficiency. When the finishing mill changes rolls, the hydraulic guide is withdrawn first, and then the rolls are withdrawn and loaded. When loading the rolls, the upper water-cutting plate of the exit guide is in contact with the rolls, that is, the tip of the upper water-cutting plate is tangent to the curved surface of the rolls, and it is ensured that there is no gap or protrusion at the position where the tip of the plate is tangent to the rolls, that is, in the direction of the incoming steel. Once the tip of the plate is not in contact with the rolls, a gap will be generated, and the gap between the upper water-cutting plate and the rolls will cause steel piling. In addition, during normal production of the finishing mill, the tip of the upper water-cutting plate will be worn due to friction with the rolls. When viewed from the side, the upper water-cutting plate becomes shorter, and the exit guide needs to be moved forward again to ensure that there is no gap or protrusion when tangent to the rolls, so that the upper water-cutting plate is tangent to the curved surface of the working rolls.

[0003] The exit guide of the finishing mill currently has the following shortcomings: the existing exit guide is a "mouth"-shaped structure, and the upper water-cutting plate is fixed on the top of the guide. When scrap steel is folded and piled up at the exit guide, since the upper water-cutting plate is fixed, it can only be cut out little by little, and the space is small and inconvenient to handle; in addition, after the tip of the upper water-cutting plate is worn, the angle of the upper water-cutting plate cannot be adjusted in time and the position cannot be limited, and it cannot be guaranteed that the tip of the upper water-cutting plate is tangent to the roller without a gap. Utility Model Content

[0004] The purpose of the utility model is to provide an outlet guide for use in the production of plate and strip steel, which is convenient for handling piled steel, so as to solve the problem that the existing upper water cutting plate is fixed on the guide and cannot slide backward when piled steel occurs, thereby making it difficult to handle the piled steel.

[0005] The utility model adopts the following technical solutions: an outlet guide for handling piled steel used in the production of plate and strip rolled steel, comprising a guide housing, which is "U"-shaped and has an open top; its bottom is connected to a hydraulic cylinder, and then moves closer to or away from the rolling roller under the drive of the hydraulic cylinder; the guide housing is formed by integrally connecting a bottom connecting plate and two protective vertical plates, and the two sides of the bottom connecting plate are respectively fixedly connected to the lower sides of the two protective vertical plates, thereby forming a "U"-shaped guide housing; the inner sides of the two protective vertical plates are provided with guide chutes along the direction of the plate and strip rolled steel, and the two guide chutes are arranged opposite to each other;

[0006] An installation rod, both ends of which extend into the two guide chutes;

[0007] The upper water cut-off plate is located below the mounting rod and is sleeved on the mounting rod, so that the upper water cut-off plate can slide along the direction of the plate and strip rolling in the guide chute along with the mounting rod, making it easy to move away from the roller after steel piling occurs, thereby freeing up space around the roller to handle the steel piling.

[0008] Furthermore, the side of the upper water cutting plate close to the rolling mill is the proximal side, and the side away from the rolling mill is the counterweight side. The proximal side of the upper water cutting plate is used to approach the rolling mill in an inwardly cut form, so that the cooling water for cooling the rolling mill flows down from both sides of the upper water cutting plate, and prevents the cooling water from flowing onto the plate and strip rolled steel. The counterweight side of the upper water cutting plate is provided with a counterweight block, and the counterweight block is used to pull the counterweight side of the upper water cutting plate downward, so that the upper water cutting plate rotates with the mounting rod as the axis, and adjusts the inclination angle of the upper water cutting plate, so that the proximal side of the upper water cutting plate approaches the rolling mill in an inwardly cut form.

[0009] Furthermore, a plurality of mounting blocks are fixedly connected to the upper side of the upper water cutting plate, and each of the mounting blocks is arranged in an "I" shape, and the arrangement direction is parallel to the direction of the mounting rod. Each of the mounting blocks is provided with a mounting hole, and each of the mounting holes is used for the mounting rod to pass through and allow the upper water cutting plate to rotate around the mounting rod as the axis.

[0010] Furthermore, it also includes: two limiting elastic mechanisms, the two limiting elastic mechanisms are located in the two guide grooves and on the side of the mounting rod away from the roller, and the limiting elastic mechanisms are used to limit the two ends of the mounting rod, so that the close side of the upper water cutting plate mounted on the mounting rod is as close to the roller as possible in an inwardly cut form.

[0011] Furthermore, the limiting elastic mechanism includes:

[0012] The limit block is fixed in the guide chute by a screw; a sleeve is fixedly connected to the side close to the roller; the direction of the sleeve is set along the direction of the plate and strip rolling; a guide hole is also opened at the edge of the limit block;

[0013] The elastic block is located between the sleeve and the mounting rod; the corresponding guide hole on the elastic block is also fixedly connected to the guide cross bar;

[0014] An elastic guide rod, one end of which extends into the sleeve, and the other end of which extends toward the mounting rod and is fixedly connected to the elastic block;

[0015] The elastic member is sleeved on the elastic guide rod; the elastic member is used to push the elastic block toward the roller, so that the elastic block rests against the mounting rod, and ensures that the close side of the upper water cutting plate is as close to the roller as possible in the form of an inward cut.

[0016] The beneficial effects of the utility model are:

[0017] When the utility model is in use, when steel pile occurs, after the fixation of the limit block and the guide chute is released, the mounting rod and the upper water-cutting plate are directly slid along the guide chute in the direction away from the roller and separated from the guide housing, thereby providing sufficient space around the roller for handling rolled steel;

[0018] The utility model provides a U-shaped guide housing, a guide chute is provided in the guide housing, and the upper water cutting plate is installed in the guide chute through a mounting rod, so that the upper water cutting plate can slide in the guide chute along the direction of the plate and strip rolled steel, so as to facilitate movement away from the roller after steel accumulation occurs, thereby freeing up space around the roller to handle the steel accumulation;

[0019] The utility model provides a counterweight block on the counterweight side of the upper water cutting plate away from the roller, and the counterweight block can pull the counterweight side of the upper water cutting plate downward, thereby causing the upper water cutting plate to rotate with the mounting rod as the axis, and adjusting the inclination angle of the upper water cutting plate, so that the side of the upper water cutting plate close to the roller side can be close to the roller in the form of an inward cut, ensuring that the tip of the upper water cutting plate is tangent to the roller without a gap;

[0020] The utility model sets a limiting elastic mechanism in the guide groove and on the side of the mounting rod away from the roller, so that the two ends of the mounting rod can be limited, thereby making the upper water cutting plate sleeved on the mounting rod as close to the roller as possible in an inwardly cut form, ensuring that the tip of the upper water cutting plate is tangent to the roller without a gap.
