AI Technical Summary
During the production process of rod wire, the scrap steel head may not fall into the scrap steel bucket due to the movement inertia and the horizontal component force of the shear force, but enters the guide groove, causing the scrap steel head to enter the downstream rolling mill together with the steel, causing the rolling mill to pile steel and production to be interrupted.
A rod wire fly shear outlet guide groove is designed, including a guide groove inlet, a hollow steel groove, a long hole and a curved guide plate. A long hole is provided at the bottom of the hollow steel trough, and a downwardly inclined arc guide plate is installed on the long hole to guide the scrap steel head entering the guide groove to fall below the guide groove.
It effectively avoids scrap steel heads entering the downstream rolling mill, prevents steel stacking and production interruptions from being carried out, and ensures the continuity and safety of the production process.

Abstract
Description
Technical Field
[0001] The utility model relates to an exit guide chute for bar and wire flying shears, belonging to the technical field of bar and wire production equipment in the metallurgical industry. Background Art
[0002] In the production of bars and wires, the guide chute is installed between equipment such as rolling mills and flying shears, and functions to support the steel material and convey it to downstream equipment during the rolling process. During normal production, after the steel material is sheared by the flying shear, it enters the downstream guide chute and rolling mill in sequence, and the cut scrap steel head falls into the scrap steel hopper below the flying shear by its own gravity. However, since the tangent direction of the flying shear cutting point is horizontally directed towards the downstream guide chute, in some cases, a part of the scrap steel head, under the action of its own movement inertia and the horizontal component of the shear force, does not fall into the scrap steel hopper but enters the guide chute. Since the traditional guide chute is a long hollow steel-passing chute and there is no way to discharge the scrap steel head, the scrap steel head will enter the downstream rolling mill together with the steel material, causing steel piling and production interruption. Content of the Utility Model
[0003] The purpose of the utility model is to provide an exit guide chute for bar and wire flying shears, which can guide the scrap steel head entering the guide chute to below the guide chute, avoid the scrap steel head entering the downstream rolling mill and causing steel piling accidents, and solve the problems existing in the background art.
[0004] The technical solution of the utility model is as follows:
[0005] An exit guide chute for bar and wire flying shears includes a guide chute inlet, a hollow steel-passing chute, a long strip hole, a guide plate and a support. The hollow steel-passing chute is arranged between the flying shear and the rolling mill, fixed on the support, the cross-section of the hollow steel-passing chute is rectangular, one end of the hollow steel-passing chute close to the flying shear is the guide chute inlet, the guide chute inlet is a funnel-shaped that becomes smaller from large, a long strip hole is arranged along the length direction at the bottom of the hollow steel-passing chute, and a guide plate arranged obliquely downward is provided on the long strip hole.
[0006] The size of the long strip hole along the length direction at the bottom of the hollow steel-passing chute matches the scrap steel head.
[0007] The length of the long strip hole along the length direction at the bottom of the hollow steel-passing chute is greater than the length of the scrap steel head, and the width is greater than the cross-sectional dimension of the scrap steel head.
[0008] The guide plate arranged obliquely downward on the long strip hole is an arc-shaped plate.
[0009] The upper end of the guide plate is welded on the hollow steel-passing chute.
[0010] The guide plate is arranged facing the direction of the scrap steel head.
[0011] The beneficial effects of the present utility model are as follows: Part of the scrap steel head entering the guide groove can be guided to below the guide groove through the long holes and the arc-shaped guide plate at the bottom of the hollow steel passing groove, avoiding the scrap steel head from entering the downstream rolling mill and causing a steel piling accident. Description of the Drawings
[0012] Figure 1 It is a schematic structural diagram of the present utility model;
[0013] In the figure: guide groove inlet 1, hollow steel passing groove 2, long strip hole 3, guide plate 4, support 5. Specific Embodiments
[0014] The following further illustrates the present utility model through examples in conjunction with the drawings.
[0015] Referring to the attached Figure 1 , a bar and wire flying shear outlet guide groove includes a guide groove inlet 1, a hollow steel passing groove 2, a long strip hole 3, a guide plate 4 and a support 5. The hollow steel passing groove 2 is arranged between the flying shear and the rolling mill, and the hollow steel passing groove 2 is fixed on the support 5. The cross-section of the hollow steel passing groove 2 is rectangular. One end of the hollow steel passing groove 2 close to the flying shear is the guide groove inlet 1, and the guide groove inlet 1 is a funnel shape that gradually becomes smaller. A long strip hole 3 is arranged along the length direction of the bottom of the hollow steel passing groove 2, and a guide plate 4 arranged obliquely downward is provided on the long strip hole 3.
[0016] In this embodiment, referring to the attached Figure 1 , the hollow steel passing groove 2 is fixed on the support 5, and the support 5 is fixed on the foundation after the flying shear. The hollow steel passing groove 2 is located between the flying shear and the rolling mill. The cross-section of the hollow steel passing groove 2 is rectangular. One end of the hollow steel passing groove 2 close to the flying shear is the guide groove inlet 1, and the guide groove inlet 1 is a funnel shape that gradually becomes smaller and converges in the rolling direction to guide the steel material.
[0017] A long strip hole 3 is opened along the length direction of the bottom of the hollow steel passing groove 2. The length of the long strip hole 3 is greater than the length of the scrap steel head, and the width is greater than the cross-sectional dimension of the scrap steel head, facilitating the scrap steel head to fall through the long strip hole 3.
[0018] The guide plate 4 is arc-shaped. According to the rolling direction, the guide plate 4 is arranged facing the direction of the scrap steel head and is inclined downward. As shown in the attached Figure 1 , the uppermost end of the guide plate 4 is welded to the long strip hole 3 at the bottom of the hollow steel passing groove 2, and the lowermost end extends below the guide groove, capable of guiding the scrap steel head falling from the long strip hole 3 so that the scrap steel head can fall to a designated position, such as in a scrap basket.
