Technical Field
[0001] This utility model relates to the field of steel rolling technology and equipment, specifically a rectangular billet 90-degree flipping conveyor device. Background Technology
[0002] In the rolling of H-shaped long products, the billets used are generally rectangular. Depending on the rolling grade, sometimes it is necessary to change the rectangular billet from a flat "I" shape to a "|" shape. For a long time, this process has relied on manual operation using a steel fork to rotate it 90 degrees, or stopping the billet and then using a turning mechanism to rotate it 90 degrees before it continues moving forward. With traditional manual operation, the workpiece temperature reaches as high as 1000℃, the working environment is harsh, and manual operation is slow, thus affecting the rolling rhythm. Using traditional mechanical turning with a stop takes about 10 seconds, which significantly slows down the production rhythm and reduces the steel temperature. Utility Model Content
[0003] The present invention aims to provide a rectangular billet 90-degree flipping and conveying device, which can quickly and stably flip the rectangular billet 90 degrees and convey the rectangular billet.
[0004] To solve the above technical problems, the specific solution adopted by this utility model is a rectangular billet 90-degree flipping conveying device, including a first conveying roller group and a second conveying roller group staggered below the first conveying roller group. The first conveying roller group is used to transfer the rectangular billet to the second conveying roller group for flipping, and the second conveying roller group is used to convey the flipped rectangular billet.
[0005] The tail end of the first conveying roller group is provided with a guide flipping assembly for flipping the rectangular blank. The guide flipping assembly includes a guide screw, a connecting screw nut, a servo motor, a tensioning cylinder and two clamping plates. The guide screw is distributed longitudinally, the connecting screw nut is installed on the guide screw, and the servo motor is used to drive the guide screw to rotate.
[0006] The two clamping plates are hinged to the connecting screw nut by a connecting plate set between their heads; the tensioning cylinder is set on one of the clamping plates to push the rectangular blank onto the other clamping plate to clamp and fix the rectangular blank or to flip and release the rectangular blank.
[0007] As another optimized solution for the above-mentioned rectangular blank 90-degree flipping conveying device: the first conveying roller group and the second conveying roller group are respectively rotatably mounted on the mounting frame with a Z-shaped cross section.
[0008] As another optimized solution for the above-mentioned rectangular billet 90-degree flipping conveying device: the first conveying roller group and the second conveying roller group each include a driving roller and a plurality of driven rollers arranged in sequence at intervals. One end of the rotating shaft on any driving roller is connected to the corresponding drive motor through a coupling. The rotating shafts of the corresponding driving roller and the plurality of driven rollers are all equipped with sprockets, and the sprockets on adjacent rotating shafts are connected to each other through chain drive.
[0009] As another optimization of the rectangular billet 90-degree flipping conveying device mentioned above: the height difference between the first conveying roller group and the second conveying roller group is less than the vertical height of the rectangular billet after flipping.
[0010] As another optimized solution for the above-mentioned rectangular billet 90-degree flipping conveying device: fixed vertical rods are respectively set at both ends of the guide screw, and adjustment holes are opened on both fixed vertical rods for the corresponding ends of the guide screw to pass through, and bearings are installed in the adjustment holes.
[0011] As another optimized solution for the above-mentioned rectangular billet 90-degree flipping conveying device: a fixed adjusting rod is provided on the outer side of each of the two fixed vertical rods. Multiple adjusting mounting holes are opened vertically on the fixed adjusting rods, and multiple adjusting holes are opened on the fixed vertical rods. Adjusting bolts are passed through the adjusting holes and the corresponding adjusting mounting holes.
[0012] As another optimized solution for the aforementioned rectangular billet 90-degree flipping conveying device: a guide rod is fixed on the connecting nut, and a guide rail is provided between the two fixed adjusting rods for the end of the guide rod to be inserted into a sliding fit.
[0013] As another optimized solution for the above-mentioned rectangular billet 90-degree flipping conveying device: the cylinder body of the tensioning cylinder is fixed in the opening set in the corresponding clamping plate, and the piston rod end of the tensioning cylinder is provided with a push plate for pushing the rectangular billet.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] In this invention, a rectangular billet is placed on a first conveyor roller group. Two clamping plates, positioned above the tail end of the first conveyor roller group, are located on either side of the rectangular billet. A piston rod of a tensioning cylinder fixed to one of the clamping plates extends, pushing the rectangular billet against the other clamping plate to clamp and fix it in place. As the first conveyor roller group rotates, the rectangular billet moves towards the second conveyor roller group. When most of the rectangular billet has moved out of the first conveyor roller group, the two clamping plates, hinged to the connecting screw nut, rotate 90 degrees clockwise under the weight of the rectangular billet. After the clamping plates rotate, the piston rod of the tensioning cylinder retracts, releasing the rectangular billet, which then falls onto the second conveyor roller group. The connecting screw nut drives the clamping plates to move towards their initial position as the guide screw rotates. The rotated rectangular billet is then moved out for rolling as the second conveyor roller group rotates. The entire process of rotating the rectangular billet requires no human intervention, quickly and stably completing the 90-degree rotation, thus improving production efficiency.

[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts of this utility model that are not described in detail in the following embodiments, such as the specifications and models of the servo motor, drive motor and tension cylinder, the installation of the first conveying roller group and the second conveying roller group on the mounting frame, and the connection nut being installed on the guide screw and being able to reciprocate with the rotation of the guide screw, should all be understood as prior art known or should be known by those skilled in the art.
[0024] like Figure 1 As shown, a rectangular billet 90-degree flipping conveying device includes a mounting frame 3, a first conveying roller group 5 and a second conveying roller group 6 disposed on the mounting frame 3, and a guide flipping assembly 1 disposed above the mounting frame 3. The mounting frame 3 has a Z-shaped cross-section. The upper horizontal section of the Z-shaped mounting frame 3 on the left side is used to install the first conveying roller group 5, and the lower horizontal section of the Z-shaped mounting frame 3 on the right side is used to install the second conveying roller group 6.
[0025] The left side of the upper horizontal section of the Z-shaped mounting frame 3 is a rolling roller table 2 for conveying the rectangular billet 4. This rolling roller table 2 is used to transfer the rectangular billet 4 before it is flipped to the first conveyor roller group 5. The right side of the lower horizontal section of the Z-shaped mounting frame 3 is a rolling roller table 2 for conveying the flipped rectangular billet 4 for rolling. The first conveyor roller group 5 and the second conveyor roller group 6 have the same structure, but the first conveyor roller group 5 is used to transfer the unflipped rectangular billet 4 to the second conveyor roller group 6 for 90-degree flipping. The second conveyor roller group 6 is used to transfer the flipped rectangular billet 4 to the rolling roller table 2 on the right side.
[0026] Both the first conveyor roller group 5 and the second conveyor roller group 6 include a drive roller and multiple conveyor rollers. The drive roller on the first conveyor roller group 5 is rotatably positioned at the leftmost position of the horizontal section above the Z-shaped mounting frame 3, and the drive roller on the second conveyor roller group 6 is rotatably positioned at the leftmost position of the horizontal section below the Z-shaped mounting frame 3. The remaining multiple conveyor rollers on the first conveyor roller group 5 and the second conveyor roller group 6 are arranged sequentially.
[0027] One drive roller and multiple conveyor rollers are rotatably mounted on mounting frame 3 via rotating shafts. Bearing seats (not shown in the figure) are provided along the length of the inner wall of mounting frame 3 for the rotating shafts to pass through and rotate. One end of the rotating shaft on any drive roller is connected to a drive motor (not shown in the figure) for driving its rotation via a coupling. Sprockets (not shown in the figure) are mounted on the rotating shafts at both ends of the drive roller and the conveyor rollers. A transmission chain (not shown in the figure) is installed between the drive roller and the sprockets on the adjacent conveyor rollers. The sprockets on adjacent rotating shafts are all connected by chain drive.
[0028] When the servo motor 101 starts, the rotating drive roller can drive the other conveying rollers to rotate synchronously through the transmission chain, so that the first conveying roller group 5 can convey the rectangular billet 4 to the second conveying roller group 6 for flipping, and the second conveying roller group 6 can convey the flipped rectangular billet 4 to the rolling roller table 2 for rolling.
[0029] like Figure 1 As shown, the guide flipping assembly 1 is located above the tail end of the first conveyor roller group 5. The guide flipping assembly 1 is used to grab the rectangular blank 4 on the first conveyor roller group 5 and flip it to place the rectangular blank 4 on the second conveyor roller group 6 when it moves above the second conveyor roller group 6. The guide flipping assembly 1 includes a guide screw 104, a connecting screw nut 103, a servo motor 101, a tensioning cylinder 107, and two clamping plates 105. The guide screw 104 is arranged along the moving direction of the rectangular blank 4, and a fixed vertical rod 102 is arranged at each end of the guide screw.
[0030] A fixed adjusting rod (not shown in the figure) is provided on the outer side of each fixed vertical rod 102. The upper end of the fixed adjusting rod is fixed to the wall or a fixed frame, and multiple adjusting mounting holes are provided on the fixed adjusting rod along its height direction. Figure 2 and Figure 4 As shown, multiple adjustment holes 1022 are spaced apart along the height direction on the two fixed vertical rods 102. The multiple adjustment holes 1022 can be aligned with the adjustment mounting holes, and an adjustment bolt (not shown in the figure) passes between the aligned adjustment mounting holes and the adjustment holes 1022. The length of the fixed vertical rods 102 when lowered can be adjusted by the adjustment bolt, so that the position of the guide screw 104 can be adjusted according to the height of the rectangular blank 4, making the device applicable to the flipping use of rectangular blanks 4 of more specifications and sizes.
[0031] like Figure 1 and Figure 4 As shown, two fixed vertical rods 102 are provided with adjustment holes 1021, each containing a bearing. The left and right ends of the guide screw 104 pass through the adjustment holes 1021 on the corresponding fixed vertical rods 102, allowing the guide screw 104 to rotate on both fixed vertical rods 102. The left end of the guide screw 104 after passing through the corresponding adjustment holes 1021 is connected to a servo motor 101, which drives the guide screw 104 to rotate.
[0032] like Figure 2As shown, the guide screw 104 is arranged along the direction of movement of the rectangular blank 4, and the connecting nut 103 is fitted on the guide screw 104. The connecting nut 103 can reciprocate along the length direction of the guide screw 104 as the guide screw 104 rotates. The lower end face of the connecting nut 103 is hinged to the connecting plate 106 arranged between the two clamping plates 105. The connecting plate 106 is fixed on the left side of the two clamping plates 105. The two clamping plates 105 and the connecting plate 106 together form a clamping cavity that can clamp and fix the rectangular blank 4.
[0033] like Figure 2 and Figure 6 As shown, the tensioning cylinder 107 is fixed to the right clamping plate 105. The right clamping plate 105 has an opening in the middle for the cylinder body of the tensioning cylinder 107 to pass through and be fixed. The piston rod of the tensioning cylinder 107 is positioned towards the other clamping plate 105. When the two clamping plates 105 are located on both sides of the rectangular blank 4, the tensioning cylinder 107 is activated, the piston rod extends and pushes the rectangular blank 4 towards the other clamping plate 105 until the rectangular blank 4 is tightly pressed against the other clamping plate 105, thus achieving the clamping and fixing of the rectangular blank 4. Figure 1 The state shown.
[0034] like Figure 1 and Figure 2 As shown, after the clamping plate 105 clamps and fixes the rectangular blank 4, the rectangular blank 4 moves with the rotation of the first conveying roller group 5. At the same time, the guide screw 104 rotates, and the connecting nut 103 drives the clamping plate 105 to move synchronously. After most of the rectangular blank 4 has moved out of the first conveying roller group 5, under the action of gravity, the rectangular blank 4 and the clamping plate 105 rotate 90 degrees clockwise around the hinge point as the rotation center until... Figure 3 The state shown.
[0035] At this moment, the piston rod of the tensioning cylinder 107 retracts, and the rectangular blank 4, no longer clamped, falls onto the second conveying roller group 6 under its own gravity. Figure 4 and Figure 5 As shown. Then, the flipped rectangular billet 4 passes through the gap formed between the two clamping plates 105 and moves to the adjacent rolling roller surface 2 for rolling as the second conveying roller group 6 rotates. Meanwhile, the connecting screw nut 103 moves toward the initial position of the left end of the guide screw 104 as the guide screw 104 rotates, and drives the clamping plate 105 to move toward the initial position, thus completing the 90-degree flip of the rectangular billet 4.
[0036] Furthermore, the height difference between the upper and lower horizontal sections of the Z-shaped mounting bracket 3 is less than the vertical height of the rectangular blank 4 after it is flipped, so that the bottom of the flipped rectangular blank 4 is close to the second conveying roller group 6, avoiding the situation where the height between the bottom of the flipped rectangular blank 4 and the second conveying roller group 6 is too high and there will be a large swaying and tilting when the clamping plate 105 is released and the rectangular blank 4 falls.
[0037] Furthermore, such as Figure 2 and Figure 6 As shown, a push plate 1071 is fixed to the end of the piston rod of the tensioning cylinder 107 to increase the contact area when the piston rod of the tensioning cylinder 107 pushes the rectangular blank 4, thereby pushing the rectangular blank 4 to press against another clamping plate 105 more stably.
[0038] Furthermore, a guide rod (not shown in the figure) is fixed on the connecting nut 103, and a guide rail (not shown in the figure) is provided between the two fixed vertical rods 102 for the end of the guide rod to be inserted into a sliding fit, so that the connecting nut 103 drives the clamping plate 105 to move back and forth stably with the rotation of the guide screw 104.
