Description

Technical Field

[0001] The invention relates to the technical field of hot-rolled flat steel, and in particular to a guiding device for hot-rolled flat steel. Background Art

[0002] The cross-section of flat steel is rectangular and can be used to manufacture hoops, mechanical parts, house frame structures and escalators. Hot rolling uses the friction of rotating rollers to drag the workpiece into the roller room, and at the same time relies on the pressure applied by the rollers to compress and deform the workpiece to form flat steel.

[0003] Specifically, the hot rolling mill is provided with multiple groups of rollers of different sizes, and there are gaps between adjacent groups of rollers. Generally, during hot rolling, the workpiece is transferred from one group of rollers to another group of rollers through transition rollers, and the discharge port of the last group of rollers is used as the discharge end of the flat steel. After the workpiece is hot-rolled to form a flat steel, the flat steel is generally directly transferred from the discharge end to the discharge roller of the unloading mechanism through the conveyor roller for cooling. In other words, the discharge roller has a fixed discharge direction, which is parallel to the axial direction of the conveyor roller. Then the entire hot rolling mill and the unloading mechanism are on the same horizontal line. However, for processing sites with limited space, the hot rolling of the hot rolling mill and the unloading process of the unloading mechanism cannot be realized, resulting in certain limitations in the unloading of the hot rolling mill.

[0018] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0019] See attached Figures 1 to 4 As shown, a guiding device for hot-rolled flat steel proposed in an embodiment of the present invention comprises a base 1, a guiding power source 2 located on the base 1, and a receiving body 3 connected to the guiding power source 2 and located above the base 1. One end of the receiving body 3 has an opening 4 connected to the outside, and the opening 4 can receive the flat steel 5 transmitted from the first direction. The guiding power source 2 is arranged at the other end of the receiving body 3. When the flat steel 5 completely enters the receiving body 3, the guiding power source 2 can drive the receiving body 3 to rotate or translate to the entrance of the unloading mechanism 200, so that the flat steel 5 is distributed along the first direction or the second direction. The receiving body 3 can also transmit the flat steel 5 toward the entrance of the unloading mechanism 200.

[0020] In this embodiment, the flat steel 5 transmitted from the hot rolling mill 100 in the first direction is received by setting the guide power source 2 and the receiving body 3, and the flat steel 5 is transmitted to the unloading mechanism 200 which is arranged in translation or at an angle with the first direction, so as to unload the flat steel 5 smoothly. That is, the flat steel 5 can change the direction of the unloading mechanism 200 during the hot rolling of the hot rolling mill 100 and the unloading process of the unloading mechanism 200, thereby saving the space occupied by the hot rolling mill 100 and its unloading mechanism 200, solving the limitation of unloading of the flat steel 5, so that the hot rolling mill 100 and its unloading mechanism 200 have a compact space and a small footprint. The technical problem that the hot rolling of the hot rolling mill 100 and the unloading process of the unloading mechanism 200 cannot be realized in a processing place with limited space, resulting in certain limitations in the unloading of the hot rolling mill 100, is solved.

[0021] Furthermore, the first direction and the second direction are perpendicular to each other, and the guide power source 2 can drive the receiving body 3 to rotate 90°. It should be noted that rotating 90° can make the overall space more compact, and it is easier to control the guide power source 2, thereby making the guidance more accurate and smooth.

[0022] Furthermore, the receiving body 3 includes a receiving bottom plate 31, two sliding side plates 32 located on both sides of the top end surface of the receiving bottom plate 31, a back plate 33 located on the opposite side of the opening 4, and an adjustment component 34 connected to the back plate 33. The receiving bottom plate 31 is provided with a plurality of grooves 311, each of which contains a rotating roller 35. The rotating roller 35 can rotate relative to the groove 311, and the axis of the rotating roller 35 is parallel to the width direction of the receiving bottom plate 31. The top end surfaces of the two sliding side plates 32 are provided with inclined slide grooves 321, and the two inclined slide grooves 321 are distributed in a "V" shape on the left and right. The bottom ends of the adjustment component 34 can slide in the two inclined slide grooves 321 respectively through the rollers 8, driving the two sliding side plates 32 to move relative to each other along the lateral direction of the receiving bottom plate 31 to clamp the flat steel 5. The inclined slide groove 321 arranged in a "V" shape cooperates with the adjustment component 34 to adaptively clamp and correct the flat steel 5 according to the width during the steering or translational movement. This prevents the flat steel 5 from being offset or thrown out during the guiding process, ensures the stability of the flat steel 5 during the guiding process, and eliminates the need for manual or mechanical clamping, thereby avoiding the impact of improper clamping on the flat steel 5.

[0023] Furthermore, the adjustment assembly 34 includes a spring 341, a push rod 342, a moving plate 343, an inclined plate 344 and a first separation mechanism 345. The push rod 342 passes through the back plate 33, and the axial direction of the push rod 342 is parallel to the length direction of the sliding side plate 32. The moving plate 343 is located at one end of the push rod 342 close to the sliding side plate 32. The spring 341 is sleeved on the push rod 342, and the two ends of the spring 341 are respectively against the back plate 33 and the moving plate 343. The inclined plate 344 includes a first inclined plate 3441 and a second inclined plate 3442, and the first inclined plate 3441 and the second inclined plate 3442 are fixed to the moving plate 343 in a front-to-back symmetrical manner. The first separation mechanism 345 is located on one side of the sliding side plate 32, and the first separation mechanism 345 has There is a first pressing wheel 3451, which can press the first oblique plate 3441, and drive the movable plate 343 toward the side of the back plate 33 through the first oblique plate 3441 to compress the spring 341, so that the spring 341 has a preload as an initial state. During the rotation process, the first pressing wheel 3451 is separated from the oblique plate 344, so that the movable plate 343 moves forward under the preload of the spring 341. At this time, the vertical distance of the movable plate 343 compared to the back plate 33 changes from h to h´ (becomes longer), thereby making the two sliding side plates 32 move toward each other to clamp the flat steel 5. That is, when the guide device rotates or leaves the first pressing wheel 3451 of the first separation mechanism 345, the movable plate 343 can move along the back plate 33 under the action of the elastic force of the spring 341. Figure 2The front end direction of the arrow A in the figure moves forward, and at the same time cooperates with the inclined slide groove 321 on the top end surface of the sliding side plate 32, so that the two sliding side plates 32 move relative to each other to clamp the flat steel 5, and can clamp and correct the position of the flat steel 5 during the turning or translation process to prevent it from being thrown out and tilted. It should also be noted that the preload force of the spring 341 can also be achieved by setting an adjustment motor and a lead screw on the outer side of the back plate 33 to control the movement of the moving plate 343, but in comparison, in this embodiment, the inclined plate 344, the first pressing wheel 3451, the spring 341 and other structures do not need to be controlled separately, and can be rotated into place to achieve automatic opening and closing and other actions.

[0024] It should be noted that the first separation mechanism 345 also includes an "L"-shaped mounting bracket mounted on the workbench 12, and the lateral end of the "L"-shaped mounting bracket has a first pressing wheel 3451, and the first pressing wheel 3451 can abut and roll on the first oblique plate 3441 to cooperate with the movement and stop of the moving plate 343. The first pressing wheel 3451 is used to press the first oblique plate 3441 and can roll along the first oblique plate 3441, so that the relative movement between the first pressing wheel 3451 and the first oblique plate 3441 is smoother.

[0025] Furthermore, a second separation mechanism 6 is provided on the unloading mechanism 200, and the second separation mechanism 6 has a second pressing wheel 61, and the second pressing wheel 61 can press the second oblique plate 3442, so that the two sliding side plates 32 move back to back and return to the initial state, at which time the vertical distance between the moving plate 343 and the back plate 33 changes from h' to h (becomes shorter). It should be noted that the second separation mechanism 6 is the same as the first separation mechanism 345, but the position is different.

[0026] Further, the base 1 includes a working support 11, a working table 12 arranged on the working support 11, a guiding power source 2 is fixedly installed on the bottom end surface of the working table 12, and the guiding power source 2 can pass through the working table 12 and be connected to the receiving body 3. Further, the working table 12 is arranged along the first direction, and the length of the working table 12 is greater than or equal to two-thirds of the length direction of the receiving body 3. It is convenient for the receiving body 3 to be better guided at the cantilever end, and the deformation of the receiving body 3 is prevented, thereby ensuring the receiving effect and the guiding effect.

[0027] Furthermore, the guide power source 2 is a rotating motor. The guide power source 2 is a servo motor, and the servo motor is convenient for adjusting both the rotation and translation of the workbench 12, and only the case of 90° rotation is shown in this embodiment.

[0028] Furthermore, the receiving body 3 further comprises a driving motor located on the receiving bottom plate 31, and the driving motor can drive the rotating roller 35 to rotate. The driving motor can rotate forward and reverse to convey the flat steel 5.

[0029] Further, the opening 4 of the receiving body 3 is provided with an auxiliary guide mechanism 7, which is provided at the opening 4 and includes a bending guide plate 71 which is formed integrally with the two sliding side plates 32. It also includes a cleaning mechanism, which includes an upper trapezoidal portion 2 76 and a cleaning strip 75, an opening 74 is provided on the lower trapezoidal portion 1 72, the upper trapezoidal portion 2 76 is connected to the top of the bending guide plate 71, and the lower trapezoidal portion 1 72 is fixedly connected with a plurality of cleaning strips 75 at intervals at the opening 74 and the upper trapezoidal portion 2 76, and the top of the cleaning strip 75 at the opening 74 and the bottom of the cleaning strip 75 on the upper trapezoidal portion 2 76 are provided with two inclined surfaces 73, so that the rolled piece can pass through the cleaning strip 75 smoothly, so that the flat steel 5 can effectively remove the oxide scale when entering the receiving body 3, thereby ensuring the effect of the flat steel 5.
