Description
Technical Field
[0001] The utility model relates to the technical field of cold rolling mills, and specifically relates to a steel plate cutting device for a cold rolling mill unit. Background Art
[0002] The steel plate cutting device of a cold rolling mill unit is a key equipment in the modern steel processing industry. With the development of industry, the requirements for the size, shape and quality of steel plates are getting higher and higher. The steel plate cutting device of a cold rolling mill unit can meet these requirements, providing precise size control and high-quality steel plate products. Traditional steel plate cutting methods mostly rely on manual or semi-automatic equipment, with low efficiency and easy to produce errors. The automatic steel plate cutting device can greatly improve production efficiency, reduce labor costs, and ensure the consistency and accuracy of cutting.
[0003] The steel plate cutting process of a cold rolling mill unit mainly involves the following steps: uncoiling, placing the steel coil on the uncoiler and preparing for cutting; cutting machine, cutting the steel plate according to the size; straightening machine, straightening the steel plate to eliminate the bending during the processing; quality inspection, inspecting the quality of the steel plate to ensure that the cut steel plate has no defects; oiling, applying rust-proof oil on the surface of the steel plate to protect the steel plate from corrosion during transportation and storage; sorting, classifying according to parameters such as the size and thickness of the steel plate; stacking, stacking the cut steel plates into stacks for convenient subsequent transportation and storage; roller table output, outputting the stacked steel plates through the roller table system for preparation of packaging or further processing.
[0004] Although the current cold rolling mill units on the market can adjust the size of the cut steel plates, due to the gravity of the steel plate itself and the impact force during the movement of the steel plate, the machine for determining the cutting size needs to be continuously calibrated. In order to reduce the number of calibrations and improve the accuracy of the steel plate size, most cold rolling mill units on the market first perform unified cutting on the steel plate and then perform secondary cutting according to the specified size to achieve the effect of reducing the number of calibrations and improving the accuracy of the steel plate size. However, this method not only wastes a large amount of steel, but also the cutting of the cold rolling mill requires huge consumption. Therefore, it is necessary to design a cold rolling mill unit that can reduce consumption and has a high cutting size accuracy. Summary of the Utility Model
[0005] Based on this, the purpose of the present utility model is to provide a steel plate cutting device for a cold rolling mill unit to solve the technical problems.
[0006] To achieve the above object, the present utility model provides the following technical solution: A steel plate slitting device for a cold rolling mill, comprising a main body. One end of the main body is provided with a feeding groove. An uncoiling device matching with the feeding groove is installed inside the main body. On both sides inside the main body, at one end of the uncoiling device far from the feeding groove, limiting blocks are provided. And on one side of the two limiting blocks away from each other, traction sliders are connected. Both of the two traction sliders are in sliding contact with the main body. On both sides of the main body, traction blocks matching with the corresponding traction sliders are connected. At one end of the two limiting blocks facing the uncoiling device, two groups of cutting wheels distributed up and down are connected. And the two cutting wheels in the same group cooperate with each other. On one side of the two limiting blocks close to each other, non-interfering limiting tooth blocks are connected. The top surface of the main body is rotationally penetrated and connected with a limiting tooth shaft, and the limiting tooth shaft penetrates through the main body and meshes with the limiting tooth blocks.
[0007] By adopting the above technical solution, the steel coil is placed into the feeding groove of the main body, and the steel coil is unrolled through the uncoiling device. According to requirements, the limiting tooth shaft is rotated, and the relative distance between the two limiting blocks is adjusted by the meshing of the limiting tooth shaft and the limiting tooth blocks, so that the cutting wheels on the limiting blocks cut both sides of the steel coil. The cut waste is discharged along the gap between the traction block and the traction slider. And since the direction of the force received by the cutting wheel is perpendicular to the force for adjusting the relative distance between the limiting blocks by the limiting tooth shaft, the cutting of the cutting wheel will not affect the limiting tooth shaft, thereby reducing the number of calibration times and improving the accuracy of the steel plate size.
[0008] The present utility model is further provided that a slitting knife is installed at one end of the main body far from the feeding groove. A guiding block is installed below one end of the main body close to the slitting knife. On both sides of the top surface of the guiding block, limiting plates are installed. A detection block is arranged between the limiting plates. On both sides of the detection block, gears are rotationally connected, and both of the two gears mesh with the corresponding top surface of the limiting plate.
[0009] By adopting the above technical solution, the detection block moves on the limiting plate through the gears, so as to adjust the length of the slit steel plate. When the steel plate touches the detection block, the slitting knife starts to cut the steel plate.
[0010] The present utility model is further provided that on the side edges of both of the two gears, limiting shafts are connected. In both of the two limiting plates, mutually matching sliding grooves are opened. And in both of the two sliding grooves, adjusting sliders are slidably connected. Around both of the two adjusting sliders, adjusting plates are connected. And on the surfaces of both of the two adjusting plates, adjusting grooves are opened. Both of the two limiting shafts are in sliding contact with the corresponding adjusting grooves. On both of the two adjusting plates, fastening bolts matching with the corresponding adjusting sliders are connected.
[0011] By adopting the above technical solution, when the steel plate touches the detection block, the detection block will be impacted. At this time, part of the impact force received by the detection block is first absorbed by the fixation between the gear and the limit plate, and the remaining impact force is transmitted to the adjustment plate through the limit shaft located in the adjustment groove. At this time, the fastening bolt fixes the adjustment slider in the adjustment groove. Since the gear is circular, the limit shaft will decompose the impact force into a force in the horizontal direction and a force perpendicular to the arc of the current point. The force perpendicular to the arc of the current point will be absorbed by the adjustment plate, thus reducing the impact force received by the connection point, thereby reducing the number of corrections and improving the accuracy of the steel plate size.
[0012] The present utility model is further arranged such that a support block is slidably connected between the chutes on the two limit plates.
[0013] By adopting the above technical solution, the support block is used to hold up the steel plate to prevent the steel plate from deforming under the influence of gravity before contacting the detection block, which affects the accuracy of the size.
[0014] The present utility model is further arranged such that a straightening device is installed at the end of the guiding block.
[0015] By adopting the above technical solution, the cut steel plate rotates downward around the support block as the axis and falls onto the guiding block, and then slides into the straightening device from the guiding block.
[0016] In summary, the present utility model mainly has the following beneficial effects:
[0017] In the present utility model, the steel coil is placed in the feeding groove of the main body and the steel coil is unrolled by the uncoiling device. Since the direction of the force received by the cutting wheel is perpendicular to the force for adjusting the relative distance between the limit tooth shaft and the limit block, the cutting of the cutting wheel will not affect the limit tooth shaft, thereby reducing the number of corrections and improving the accuracy of the steel plate size; when the steel plate touches the detection block, the detection block will be impacted. At this time, part of the impact force received by the detection block is first absorbed by the fixation between the gear and the limit plate, and the remaining impact force is transmitted to the adjustment plate through the limit shaft located in the adjustment groove, thus reducing the impact force received by the connection point, thereby reducing the number of corrections and improving the accuracy of the steel plate size.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.
[0025] Next, the embodiments of the present utility model will be described according to its overall structure.
[0026] A steel plate slitting device for a cold rolling mill unit, as Figures 1-5 shown, includes a main body 1. A feeding trough 4 is provided at one end of the main body 1. An uncoiling device 2 cooperating with the feeding trough 4 is installed inside the main body 1. Limit blocks 6 are provided on both sides inside the main body 1 at the end of the uncoiling device 2 away from the feeding trough 4. Traction sliders 8 are connected to the sides of the two limit blocks 6 away from each other. The two traction sliders 8 are in sliding contact with the main body 1. Traction blocks 7 cooperating with the corresponding traction sliders 8 are connected to both sides of the main body 1. Two groups of cutting wheels 5 distributed up and down are connected to the ends of the two limit blocks 6 facing the uncoiling device 2. The two cutting wheels 5 in the same group cooperate with each other. Limit tooth blocks 9 that do not interfere with each other are connected to the sides of the two limit blocks 6 close to each other. A limit tooth shaft 10 is rotatably penetrated through the top surface of the main body 1. The limit tooth shaft 10 penetrates through the main body 1 and meshes with the limit tooth blocks 9. Put the steel coil into the feeding trough 4 of the main body 1, and unfold the steel coil through the uncoiling device 2. According to requirements, rotate the limit tooth shaft 10, and adjust the relative distance between the two limit blocks 6 by the meshing of the limit tooth shaft 10 and the limit tooth blocks 9, so that the cutting wheels 5 on the limit blocks 6 cut both sides of the steel coil. The cut waste is discharged along the gap between the traction block 7 and the traction slider 8. And since the direction of the force received by the cutting wheel 5 is perpendicular to the force for adjusting the relative distance between the limit blocks 6 by the limit tooth shaft 10, the cutting of the cutting wheel 5 will not affect the limit tooth shaft 10, thereby reducing the number of corrections and improving the accuracy of the steel plate size.
[0027] At one end of the main body 1 away from the material feeding chute 4, a slitting knife 11 is installed. Below one end of the main body 1 close to the slitting knife 11, a guiding block 12 is installed. On both sides of the top surface of the guiding block 12, limiting plates 13 are installed. Between the limiting plates 13, a detection block 16 is arranged. On both sides of the detection block 16, gears 17 are rotatably connected, and both of the two gears 17 are meshed with the corresponding top surfaces of the limiting plates 13. The detection block 16 moves on the limiting plates 13 through the gears 17, so as to adjust the length of the slit steel plate. When the steel plate touches the detection block 16, the slitting knife 11 starts to cut the steel plate.
[0028] On the side edges of both of the two gears 17, limiting shafts 18 are connected. In both of the two limiting plates 13, mutually cooperating sliding grooves 14 are formed, and in both of the two sliding grooves 14, adjusting sliders 21 are slidably connected. Around both of the two adjusting sliders 21, adjusting plates 19 are connected, and on the surfaces of both of the two adjusting plates 19, adjusting grooves 20 are formed. Both of the two limiting shafts 18 are in sliding contact with the corresponding adjusting grooves 20. On both of the two adjusting plates 19, fastening bolts 22 cooperating with the corresponding adjusting sliders 21 are connected. When the steel plate touches the detection block 16, the detection block 16 will be impacted. At this time, part of the impact force received by the detection block 16 is absorbed by the fixation between the gear 17 and the limiting plate 13 first, and the remaining impact force is transmitted to the adjusting plate 19 through the limiting shaft 18 located in the adjusting groove 20. At this time, the fastening bolt 22 fixes the adjusting slider 21 in the adjusting groove 20. Since the gear 17 is circular, the limiting shaft 18 will decompose the impact force into a horizontal force and a force perpendicular to the arc of the current point. The force perpendicular to the arc of the current point will be absorbed by the adjusting plate 19, so as to reduce the impact force received by the connection point, thereby reducing the number of calibration times and improving the accuracy of the steel plate size.
[0029] A support block 15 is slidably connected between the sliding grooves 14 on the two limiting plates 13. The support block 15 is used to support the steel plate to prevent the steel plate from deforming under the influence of gravity before contacting the detection block 16, which affects the dimensional accuracy.
[0030] At the end of the guiding block 12, a straightening device 3 is installed. The cut steel plate rotates downward around the support block 15 and drops onto the guiding block 12, and then slides into the straightening device 3 from the guiding block 12.
[0031] Working principle: Place the steel coil into the material feeding groove 4 of the main body 1, and unwind the steel coil through the uncoiling device 2. According to requirements, rotate the limit tooth shaft 10, and adjust the relative distance between the two limit blocks 6 by meshing the limit tooth shaft 10 with the limit tooth block 9, so that the cutting wheels 5 on the limit blocks 6 cut both sides of the steel coil. The cut waste is discharged along the gap between the traction block 7 and the traction slider 8. And since the direction of the force received by the cutting wheel 5 is perpendicular to the force for adjusting the relative distance between the limit blocks 6 by the limit tooth shaft 10, the cutting of the cutting wheel 5 will not affect the limit tooth shaft 10, thereby reducing the number of calibration times and improving the accuracy of the steel plate size. The steel plate with both sides cut continues to move. When the steel plate touches the detection block 16, the slitting knife 11 is activated to cut the steel plate. When the steel plate touches the detection block 16, the detection block 16 will be impacted. At this time, part of the impact force received by the detection block 16 is first absorbed by the fixation between the gear 17 and the limit plate 13, and the remaining impact force is transmitted to the adjusting plate 19 through the limit shaft 18 located in the adjusting groove 20. At this time, the fastening bolt 22 fixes the adjusting slider 21 in the adjusting groove 20. Since the gear 17 is circular, the limit shaft 18 will decompose the impact force into a horizontal force and a force perpendicular to the arc of the current point. The force perpendicular to the arc of the current point will be absorbed by the adjusting plate 19, which reduces the impact force received by the connection point, thereby reducing the number of calibration times and improving the accuracy of the steel plate size. Among them, the support block 15 is used to support the steel plate to prevent the steel plate from deforming under the influence of gravity before touching the detection block 16, which affects the dimensional accuracy. Finally, the cut steel plate rotates downward around the support block 15 and falls onto the guide block 12, and then slides into the straightening device 3 from the guide block 12.
