Description

Technical Field

[0001] The invention belongs to the technical field of supporting facilities of rolling mills, and in particular 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 outlet of the finishing mill is now 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 When the finishing mill changes rolls, the hydraulic guide is withdrawn first, and then the rolls are withdrawn and loaded.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 outlet 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 roll, that is, in the direction of the incoming steel. Once the tip of the plate is not in contact with the roll, a gap will be generated, and the gap between the upper water-cutting plate and the roll will cause steel piling. In addition, during the 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 outlet guide needs to be moved forward again to ensure that there is no gap or protrusion tangent to the rolls, so that the upper water-cutting plate is tangent to the curved surface of the working roll.

[0003] The exit guide of the finishing mill 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. Summary of the invention

[0004] The purpose of the present invention is to provide an exit 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, thus making it difficult to handle the piled steel.

[0005] The present invention adopts the following technical scheme: an exit 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 roller direction 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 slots along the direction of the plate and strip rolled steel, and the two guide slots are arranged opposite to each other;

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

[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 with the mounting rod, so as to facilitate movement 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 close side, and the side away from the rolling mill is the counterweight side. The close 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 around the mounting rod as the axis, and adjusts the inclination angle of the upper water cutting plate, so that the close 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, each of the mounting blocks is arranged in a straight line, and the arrangement direction is parallel to the direction of the mounting rod, and 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 slide grooves and on the side of the mounting rod away from the roller, 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 comprises:

[0012] The limit block is fixed in the guide chute by a screw rod; a sleeve is fixedly connected to the side close to the roller; the direction of the sleeve is arranged 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 elastic block is also fixedly connected with a guide cross bar corresponding to the guide hole;

[0014] An elastic guide rod, one end of which extends into the sleeve, and the other end of which extends in the direction of 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, make the elastic block against the mounting rod, and ensure that the close side of the upper water cutting plate is as close to the roller as possible in the form of incision.

[0016] The beneficial effects of the present invention are:

[0017] When the present invention is in use, when steel pile occurs, after the fixing of the limit block and the guide chute is released, the mounting rod and the upper water cut plate can be directly slid along the guide chute in a direction away from the roller and separated from the guide housing, thereby providing sufficient space around the roller to handle the rolled steel;

[0018] The present invention provides a U-shaped guide housing, a guide chute in the guide housing, and installs the upper water cutter plate in the guide chute through a mounting rod, so that the upper water cutter plate can slide in the guide chute along the direction of the plate and strip steel rolling, so as to facilitate the upper water cutter plate to move away from the roller after the steel pile occurs, thereby freeing up space around the roller to handle the steel pile;

[0019] The present invention arranges 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 an inwardly cut form, ensuring that the tip of the upper water cutting plate is tangent to the roller without a gap;

[0020] The present invention can limit the two ends of the mounting rod by arranging a limiting elastic mechanism in the guide groove and on the side of the mounting rod away from the roller, so that the upper water cutting plate sleeved on the mounting rod is 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.

[0026] The present invention provides an outlet guide for facilitating the handling of piled steel in the production of plate and strip rolled steel, such as Figure 1 As shown, it includes a guide housing 1, a mounting rod 2, and an upper water cutting plate 3.

[0027] The guide housing 1 is "U"-shaped, and the top of the guide housing 1 is open; the bottom of the guide housing 1 is connected to the hydraulic cylinder, and then driven by the hydraulic cylinder to move closer to or away from the roller; the hydraulic cylinder is used to control the coarse adjustment of the guide housing 1, so that the guide housing 1 can be close to the roller, which is convenient for fine adjustment.

[0028] The guide shell 1 is formed by a bottom connecting plate and two protective vertical plates connected as one body, 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 shell 1; the inner sides of the two protective vertical plates are provided with guide grooves 4 along the direction of the plate and strip rolled steel, and the two guide grooves 4 are arranged opposite to each other.

[0029] The two ends of the mounting rod 2 extend into the two guide chutes 4; the upper water cut plate 3 is located below the mounting rod 2 and is sleeved on the mounting rod 2, so that the upper water cut plate 3 can slide along the direction of the plate and strip rolling in the guide chutes 4 with the mounting rod 2, so as to facilitate the movement away from the roller after the steel pile occurs, thereby freeing up space around the roller to handle the steel pile;

[0030] The side of the upper water cutting plate 3 close to the rolling mill is the close side 5, and the side away from the rolling mill is the counterweight side. The close side 5 of the upper water cutting plate 3 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 3 and prevents the cooling water from flowing onto the plate and strip rolled steel. A counterweight block is provided on the counterweight side of the upper water cutting plate 3, and the counterweight block is used to pull the counterweight side of the upper water cutting plate 3 downward, so that the upper water cutting plate 3 rotates around the mounting rod 2 as the axis, and adjusts the inclination angle of the upper water cutting plate 3, so that the close side 5 of the upper water cutting plate 3 approaches the rolling mill in an inwardly cut form.

[0031] A plurality of mounting blocks 6 are fixedly connected to the upper side of the upper water cut-off plate 3. The mounting blocks 6 are arranged in a straight line and the arrangement direction is parallel to the direction of the mounting rod 2. A mounting hole is opened on each mounting block 6. Each mounting hole is used for the mounting rod 2 to pass through and allows the upper water cut-off plate 3 to rotate with the mounting rod 2 as the axis.

[0032] The present invention also includes two limiting elastic mechanisms 7, which are located in the two guide grooves 4 and on the side of the mounting rod 2 away from the roller. The limiting elastic mechanisms 7 are used to limit the two ends of the mounting rod 2, so that the close side 5 of the upper water cutting plate 3 mounted on the mounting rod 2 is as close to the roller as possible in an inwardly cut form.

[0033] The structure of the limiting elastic mechanism 7 is as follows: Figure 2 As shown, it includes: a limit block 8, an elastic block 11, an elastic guide rod 9, and an elastic member.

[0034] The limit block 8 is fixed in the guide chute 4 by a screw rod; a sleeve is fixedly connected to the side of the limit block 8 close to the roller; the direction of the sleeve is arranged along the direction of the plate and strip rolling; a guide hole is also opened at the edge of the limit block 8.

[0035] The elastic block 11 is located between the sleeve and the mounting rod 2; a guide cross bar 10 is also fixedly connected to the corresponding guide hole on the elastic block 11; one end of the elastic guide rod 9 extends into the sleeve, and the other end of the elastic guide rod 9 extends toward the mounting rod 2 and is fixedly connected to the elastic block 11.

[0036] The elastic member is sleeved on the elastic guide rod 9; the elastic member is used to push the elastic block 11 toward the roller, so that the elastic block 11 abuts against the mounting rod 2, and ensures that the close side 5 of the upper water cutting plate 3 is as close to the roller as possible in an inscribed form.

[0037] The present invention sets a "U"-shaped guide shell 1, sets a guide chute 4 in the guide shell 1, and installs the upper water cutting plate 3 in the guide chute 4 through the installation rod 2, so that the upper water cutting plate 3 can slide in the guide chute 4 along the direction of the plate and strip steel rolling, so as to move away from the roller after steel pile occurs, thereby freeing up space around the roller to handle the steel pile.

[0038] The present invention arranges a counterweight block on the counterweight side of the upper water cutting plate 3 away from the roller, and the counterweight block can pull the counterweight side of the upper water cutting plate 3 downward, thereby causing the upper water cutting plate 3 to rotate with the mounting rod 2 as the axis, and adjusting the inclination angle of the upper water cutting plate 3, so that the side of the upper water cutting plate 3 close to the roller side can be close to the roller in an inwardly cut form, ensuring that the tip of the upper water cutting plate 3 is tangent to the roller without a gap;

[0039] The present invention can limit the two ends of the mounting rod 2 by arranging a limiting elastic mechanism 7 in the guide groove 4 and on the side of the mounting rod 2 away from the rolling roller, so that the upper water cutting plate 3 mounted on the mounting rod 2 can be as close to the rolling roller as possible in an inwardly cut form, ensuring that the tip of the upper water cutting plate 3 is tangent to the rolling roller without a gap.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
