Description

Technical Field

[0001] The utility model relates to the technical field of steel production, in particular to a sampling and transfer system for steel production. Background Art

[0002] In the process of round steel production and manufacturing, at the beginning when long round steel enters the cold shear machine for cutting, the operator needs to dial the incoming round bar into the shear groove of the lower shear blade of the cold shear machine, and the round bar is pressed and fixed by the pressure roller to complete the shearing process. When the round bar is initially sheared, sampling and marking are required, and finally the composition of the round bar is detected to determine whether the composition of the round bar is qualified.

[0003] Currently, the staff holds a receiving box and extends the receiving box into the cold shear machine on one side of the cutting tool assembly. In this way, the cut round bar directly falls into the receiving box, and then the receiving box is withdrawn from the cold shear machine, and the round bar in the receiving box is put into the transfer box, and then the transfer box is sent to the marking area for manual marking, and finally the round bar is sent to the composition detection area for composition detection.

[0004] Since currently manual sampling is required and the round bar samples need to be carried and transferred to the marking area, and this process is all carried out manually, it leads to high labor intensity of workers, low production efficiency, and due to the temperature of the round steel being about 500 degrees Celsius, there are certain risks in the sampling, carrying and transferring processes.

Specific embodiments

[0046] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0047] As Figures 1 - 10 shown, an embodiment of the present utility model provides a steel production sampling transfer system, including a sampling blanking device 2 and a conveyor 3; the sampling blanking device 2 includes a sampling device and a blanking device 8; the sampling device has a first station and a second station, the blanking device 8 has a third station and a fourth station, and the conveyor 3 has a fifth station and a sixth station; the second station is adjacent to the third station, and the fourth station is adjacent to the fifth station; wherein:

[0048] When the sampling device is at the first station, the sampling device is used to receive the cut steel samples in the cold shear 1; when the sampling device is at the second station, the sampling device is used to turn out the taken steel samples into the blanking device 8 at the third station;

[0049] When the blanking device 8 is at the third working position, the blanking device 8 is used to receive the steel sample turned out by the sampling device; when the blanking device 8 is at the fourth working position, the blanking device 8 is used to turn out the steel sample onto the fifth working position of the conveyor 3, and the conveyor 3 is used to convey the steel sample at the fifth working position to the sixth working position.

[0050] In this embodiment, the first working position of the sampling device is inside the cold shearer 1, the second working position of the sampling device is outside the cold shearer 1 and close to the third working position of the blanking device 8, the fifth working position of the conveyor 3 is close to the fourth working position of the blanking device 8, and the sixth working position of the conveyor 3 is close to the laser marking machine.

[0051] When sampling and handling the round bar, first, the sampling device at the first working position receives the steel sample cut off in the cold shearer 1, then the sampling device switches to the second working position, and the sampling device at the second working position turns out the taken steel sample into the blanking device 8 at the third working position. After that, the blanking device 8 switches to the fourth working position to turn out the steel sample onto the fifth working position of the conveyor 3, and the conveyor 3 conveys the steel sample at the fifth working position to the sixth working position.

[0052] In this way, manual sampling is not required, the sampling efficiency of the round bar is improved, and the risk of workers being scalded by the round bar during sampling can be avoided, so the safety performance is improved. Moreover, the sampling device cooperates with the blanking device 8 to place the taken sample on the conveyor 3, and the conveyor 3 conveys the sample to the laser marking machine, eliminating the need for manual handling and transfer, reducing the labor burden of workers, and improving the production efficiency.

[0053] As a preferred embodiment, as Figure 2 shown, the sampling device includes a linear drive assembly 5, a receiving box 6 and a first flipping mechanism 7. When the linear drive assembly 5 is in the first working state, the linear drive assembly 5 drives the receiving box 6 to extend into the lower part of the cutter assembly of the cold shearer 1 along the first direction to receive the cut steel; when the linear drive assembly 5 is in the second working state, the linear drive assembly 5 drives the receiving box 6 to move along the second direction to withdraw from the cold shearer 1; the first direction and the second direction are opposite. Specifically, as Figure 1 shown, the first end of the linear drive assembly 5 extends into the cold shearer 1, and its second end is located outside the cold shearer 1. The first direction is from the second end to the first end of the linear drive assembly 5, and the second direction is from the first end to the second end of the linear drive assembly 5.

[0054] Further, the first flipping mechanism 7 is installed on the linear driving assembly 5 and is connected to the material receiving box 6. When the first flipping mechanism 7 is in the flipping mode, the first flipping mechanism 7 drives the material receiving box 6 to flip so as to turn out the steel in the material receiving box 6 and make it fall into the blanking device 8 at the third station; when the first flipping mechanism 7 is in the reset mode, the first flipping mechanism 7 drives the material receiving box 6 to return to the upright position.

[0055] In this way, when taking the sample, first, the linear driving assembly 5 drives the material receiving box 6 to move towards the cold shearing machine 1 and extend below the cutting tool assembly of the cold shearing machine 1. The cut steel falls into the material receiving box 6. Then, the linear driving assembly 5 drives the material receiving box 6 to move away from the cold shearing machine 1 to withdraw from the cold shearing machine 1 to a set position. Immediately afterwards, the first flipping mechanism 7 is adjusted to the flipping mode, so as to drive the material receiving box 6 to flip to turn out the steel in the material receiving box 6 and make it fall into the blanking device 8 at the third station. Finally, the first flipping mechanism 7 switches to the reset mode to drive the material receiving box 6 to return to the upright position, so as to perform the next sampling operation. Through the mutual cooperation of the linear driving assembly 5, the material receiving box 6 and the first flipping mechanism 7, the automatic sampling work is realized. The whole sampling work is convenient, fast, time-saving and labor-saving.

[0056] As a preferred embodiment, as Figure 2 shown, the steel production sampling transfer system includes a mobile trolley 4. A push handle 401 is installed at the front of the mobile trolley 4, and the angle of the push handle 401 is adjustable. A bearing frame 402 is installed on the mobile trolley 4 along its length direction. The sampling device is installed on the bearing frame 402, and the blanking device 8 is installed on the mobile trolley 4. In this way, the mobile trolley 4 can be used to move the sampling device and the blanking device 8, ensuring flexibility.

[0057] Preferably, as Figure 3 shown, the linear driving assembly 5 includes a housing 501, a sliding plate 502 and a driving mechanism. The housing 501 is in the shape of a slender long box. The sliding plate 502 is slidably installed on the side of the housing 501. The driving mechanism is installed in the housing 501 for driving the sliding plate 502 to move along the length direction of the housing 501. The first flipping mechanism 7 is installed on the sliding plate 502, and one end of the first flipping mechanism 7 is connected to the material receiving box 6 for driving the material receiving box 6 to rotate. Further, as Figure 2 shown, the housing 501 is detachably installed on the bearing frame 402, so that the length direction of the housing 501 is consistent with the length direction of the bearing frame 402.

[0058] When sampling, the moving trolley 4 can be pushed so that the end of the housing 501 in the linear drive assembly 5 extends into the cold shear 1 and is close to one side of the lower knife seat of the cutter assembly. Then the driving mechanism drives the sliding plate 502 to drive the material receiving box 6 to move in the direction close to the cold shear 1, so that the material receiving box 6 extends into the interior of the cold shear 1, and the upper cutter in the cutter assembly cooperates with the lower knife seat to cut the round rod, and the cut round rod falls into the material receiving box 6. As the driving mechanism drives the sliding plate 502 to drive the material receiving box 6 to move away from the cold shear 1, the material receiving box 6 withdraws from the cold shear 1 and returns to its original position. In this embodiment, there is no need for manual sampling, and the automated sampling process can be completed, which ensures the safety of sampling and improves the efficiency of sampling.

[0059] As a preferred embodiment, in this embodiment, if Figure 4 As shown, the driving mechanism includes a driving sprocket 509, a driven sprocket 510, a chain and a first motor 511, wherein the driving sprocket 509 and the driven sprocket 510 are rotatably installed in the shell 501 in sequence along the length direction of the shell 501. Specifically, the driving sprocket 509 is rotatably installed at the end of the shell 501 away from the cold shearing machine 1, and the driven sprocket 510 is rotatably installed at the end of the shell 501 close to the cold shearing machine 1. The chain transmission is installed between the driving sprocket 509 and the driven sprocket 510. The first motor 511 is fixedly installed on the side of the shell 501, and the output end of the first motor 511 is connected to the driving sprocket 509. Furthermore, the sliding plate 502 is slidably installed on the right side of the shell 501, and part of the sliding plate 502 is connected to the chain. For example Figure 2 As shown, the first turning mechanism 7 is installed on the sliding plate 502 , and the first turning mechanism 7 is connected to the receiving box 6 .

[0060] When the driving mechanism drives the sliding plate 502 to move along the length direction of the shell 501, the driving sprocket 509 is driven to rotate through the first motor 511. Since the chain transmission is installed between the driving sprocket 509 and the driven sprocket 510, the chain rotates. The sliding plate 502 is connected to the chain, so that the sliding plate 502 moves along the length direction of the shell 501 as the chain rotates, and the material receiving box 6 moves as the sliding plate 502 moves.

[0061] As an alternative embodiment, to ensure that the sliding plate 502 can slide stably on the outer shell 501 and reduce the friction between the sliding plate 502 and the outer shell 501, an upper hole body and a lower hole body are successively formed along the length direction on the side plate 512 on the right side of the outer shell 501. The widths and lengths of the upper hole body and the lower hole body are the same. Both the upper hole body and the lower hole body are long holes, and the lengths of the upper hole body and the lower hole body are slightly smaller than the length of the front panel 301. The upper hole body is located above the lower hole body. Further, a bearing rail one 503 is installed on the inner bottom wall of the upper hole body, and a bearing rail two 504 is installed on the inner bottom wall of the lower hole body. The bearing rail one 503 and the bearing rail two 504 are exactly the same, and the length of the bearing rail one 503 is slightly smaller than the length of the upper hole body.

[0062] Further, as Figure 5 and Figure 6 shown, a wheel one 513 and a wheel two 515 are installed on the back surface of the sliding plate 502. The wheel one 513 is located above the wheel two 515. The distance between the bearing rail one 503 and the bearing rail two 504 is the same as the distance between the wheel one 513 and the wheel two 515. When installing the sliding plate 502, the wheel one 513 on the back surface of the sliding plate 502 can be installed on the bearing rail one 503, and at the same time, the wheel two 515 can be installed on the bearing rail two 504.

[0063] It should be noted that the cross-sections of the bearing rail one 503 and the bearing rail two 504 are convex-shaped. Both the wheel one 513 and the wheel two 515 include a shaft body and wheel rims on both sides of the shaft body. The inner walls of the two wheel rims on the wheel one 513 are attached to both sides of the top of the bearing rail one 503, and the inner walls of the two wheel rims on the wheel two 515 are attached to both sides of the top of the bearing rail two 504. In this way, the friction between the sliding plate 502 and the outer shell 501 can be changed into rolling friction, reducing the frictional force and improving the moving efficiency. Second, the rollers cannot be separated from the bearing rails, so as to hold the sliding plate 502 and prevent the sliding plate 502 from being separated from the outer shell 501.

[0064] Optionally, as Figure 6 shown, a connecting piece 514 is installed on the back surface of the sliding plate 502. The connecting piece 514 is at the same height as the wheel one 513, and the connecting piece 514 is used to connect with a chain.

[0065] To facilitate pouring out the steel in the material receiving box 6 and pouring the steel onto the blanking device 8. Preferably, as Figure 5As shown in the figure, a first flipping mechanism 7 is installed on the front surface of the sliding plate 502. The first flipping mechanism 7 includes a second motor 701, a coupling 702, and a drive shaft 703. The second motor 701 is fixedly installed on the front surface of the sliding plate 502 through an L-shaped angle seat. A rectangular frame is fixedly installed on the front surface of the sliding plate 502. Bearings are installed on both sides of the left side of the rectangular frame respectively. The drive shaft 703 passes through the two bearings. One end of the drive shaft 703 close to the second motor 701 is connected to the output end of the second motor 701 through the coupling 702. One end of the drive shaft 703 close to the receiving box 6 is detachably connected to the receiving box 6 through a flange member.

[0066] In this way, when it is necessary to pour out the round steel in the receiving box 6, the second motor 701 drives the coupling 702 and the drive shaft 703 to rotate, and finally drives the receiving box 6 to rotate together to turn out the round steel in the receiving box 6.

[0067] In order to better detect whether the receiving box 6 extends into the set position of the cold shear 1, as Figure 3 shown, a proximity switch 508 is installed on the top of one end of the housing 501 that extends into the cold shear 1, and a signal trigger 507 is installed at the top position on the front surface of the sliding plate 502. In this way, when the sliding plate 502 drives the receiving box 6 to move towards the inside of the cold shear 1 to the set position, at this time the signal trigger 507 just moves to the proximity switch 508, and the proximity switch 508 quickly issues an electrical instruction, and the controller controls the first motor 511 to pause so that the receiving box 6 can just receive all the cut round steel.

[0068] Optionally, as Figure 3 shown, a drag chain carrier frame 505 for accommodating a drag chain 506 is installed on the top of the housing 501 along its length direction. A drag chain connecting member in the shape of an inverted L-shaped plate is installed on the sliding plate 502. One end of the drag chain 506 in the drag chain carrier frame 505 is connected to the drag chain connecting member. The drag chain 506 is used to induct signal wires.

[0069] As Figure 1 and Figure 2As shown in the figure, in order to automatically place the round bar samples in the receiving box 6 onto the conveyor 3, a blanking device 8 is specifically installed on the right side of the moving trolley 4. The blanking device 8 receives the round steel samples in the receiving box 6 and places the round steel samples onto the conveyor 3. The blanking device 8 includes a blanking hopper 9, a second flipping mechanism 12, and a linear guide mechanism 11; the linear guide mechanism 11 includes a guide mechanism and a driving device. The guide mechanism is inclined and lower than the receiving box 6. The first end of the guide mechanism is close to the receiving box 6, and the first end of the guide mechanism is lower than its second end; both the blanking hopper 9 and the second flipping mechanism 12 are slidably installed on the guide mechanism; when the blanking hopper 9 is in the third working position, the blanking hopper 9 is located at the first end of the guide mechanism; when the blanking hopper 9 is in the fourth working position, the blanking hopper 9 is located at the second end of the guide mechanism; the driving device is used to drive the blanking hopper 9 to switch between the third working position and the fourth working position; the second flipping mechanism 12 has a first working state and a second working state. When the second flipping mechanism 12 is in the first working state, the second flipping mechanism 12 drives the blanking hopper 9 in the fourth working position to flip so as to turn out the steel in the blanking hopper 9 onto the fifth working position of the conveyor 3; when the second flipping mechanism 12 is in the second working state, the second flipping mechanism 12 drives the blanking hopper 9 in the third working position to return to the upright position to receive the steel samples turned out by the receiving box 6.

[0070] Specifically, when the blanking hopper 9 is in the third working position, the blanking hopper 9 is located at the first end of the guide mechanism. At this time, the blanking hopper 9 is located below the receiving box 6 and is used to carry the steel samples turned out by the receiving box 6. The driving device can drive the blanking hopper 9 to switch between the third working position and the fourth working position, so as to drive the blanking hopper 9 to gradually approach the conveyor 3 and its height is also continuously increasing. Finally, the blanking hopper 9 is moved to the second end of the guide mechanism. At this time, the blanking hopper 9 is close to the fifth working position of the conveyor 3 and is higher than the fifth working position of the conveyor 3. Then, the second flipping mechanism 12 drives the blanking hopper 9 in the fourth working position to flip so as to turn out the steel in the blanking hopper 9 onto the fifth working position of the conveyor 3, and then the conveyor 3 conveys the steel located at the fifth working position to the sixth working position of the conveyor 3. At the same time, the driving device drives the blanking hopper 9 in the fourth working position to switch to the third working position, so that the blanking hopper 9 is moved to the first end of the guide mechanism. Then, the second flipping mechanism 12 drives the blanking hopper 9 in the third working position to return to the upright position to continue receiving the steel samples turned out by the receiving box 6. Therefore, the blanking device 8 in this embodiment plays the role of transporting and transferring the steel samples, so as to smoothly transfer the steel samples onto the conveyor 3 without manually transporting the steel samples in the receiving box 6 onto the conveyor 3, improving the production efficiency.

[0071] As Figure 2As shown, a notch is formed at the middle position on the right side of the moving trolley 4. Plate bodies are respectively fixed on the two inner walls before and after the notch. A bracket assembly 10 is installed between the two plate bodies, and a linear guide mechanism 11 is installed on the bracket assembly 10. Specifically, as Figure 8 shown, the bracket assembly 10 includes two support plates 1001 and two fixing rods 1002. The two support plates 1001 are right-angled triangular plates. The two support plates 1001 are respectively fixed on the two plate bodies in the notch by bolts, and the inclined surfaces of the support plates 1001 face upward, that is, from the left side to the right side of the moving trolley 4, the left end of the support plate 1001 is lower than its right end. The two fixing rods 1002 are fixedly installed between the two support plates 1001 to connect the two support plates 1001 and enhance the stability of the bracket assembly 10.

[0072] As Figure 8 shown, the linear guide mechanism 11 includes a first cylinder 1105, two moving plates 1103, two tracks 1101 and a connecting pipe 1104. The two tracks 1101 are respectively fixedly installed on the top inclined surfaces of the two support plates 1001 so that the tracks 1101 are inclined. Two sliding seats 1102 are slidably installed on each track 1101. The two sliding seats 1102 on each track 1101 are connected by a moving plate 1103. The top of the sliding seat 1102 is fixedly connected to the moving plate 1103. One end of the connecting pipe 1104 is fixed to the right end of one moving plate 1103, and the other end is fixed to the right end of the other moving plate 1103.

[0073] Furthermore, as Figure 10 shown, the first cylinder 1105 is installed on a fixing rod 1002 through a mounting seat, and the other end is connected to the connecting pipe 1104. The feeding hopper 9 is rotatably installed between the two moving plates 1103. A second flipping mechanism 12 is installed on one moving plate 1103 to drive the feeding hopper 9 to flip.

[0074] When the receiving box 6 in the sampling device retracts to the set position, at this time the receiving box 6 is aligned with the feeding hopper 9, achieving as Figure 2The state shown. After that, the first cylinder 1105 extends to push the connecting pipe 1104. Since the two moving plates 1103 are fixed by the connecting pipe 1104, and the moving plates 1103 are slidably mounted on the track 1101 through the sliding seats 1102, when the first cylinder 1105 extends, it will push the moving plates 1103 to move to the right side of the track 1101 on the track 1101. And the hopper 9 is installed between the two moving plates 1103, so it will also move to the right side of the track 1101, so that the hopper 9 gradually approaches the conveyor 3, and the height of the hopper 9 gradually increases until the hopper 9 moves above the conveyor 3, or the right side of the hopper 9 is above the conveyor 3. After that, the second turning mechanism 12 drives the hopper 9 to rotate to adjust the inclination angle of the hopper 9, so that the left side of the hopper 9 is high and the right side is low, so that the round steel in the hopper 9 will smoothly roll from the hopper 9 onto the conveyor 3. Such a transfer has high efficiency, is convenient to operate, and saves time and effort.

[0075] As a preferred embodiment, as Figure 9 shown, the second turning mechanism 12 includes a turning shaft, two support seats 1201, a curved rod 1202, a second cylinder 1203 and a hinge seat 1204. Among them, the two support seats 1201 are respectively installed on the two moving plates 1103. The support seats 1201 are in the shape of inclined plates, and the included angle formed between the support seats 1201 and the moving plates 1103 is an acute angle. The hinge seat 1204 is installed on the moving plate 1103 in front of the hopper 9. The first end of the curved rod 1202 is connected to the turning shaft, one end of the second cylinder 1203 is hinged to the hinge seat 1204, and the other end is hinged to the second end of the curved rod 1202. The bottom of the hopper 9 is fixedly connected to the turning shaft.

[0076] In this way, as the driving mechanism drives the sliding plate 502 to drive the receiving box 6 to move away from the cold shear 1, the receiving box 6 is withdrawn from the cold shear 1 and retracted to the original position, that is, the receiving box 6 is in the second working position and retracted to as Figure 2The state shown is such that the material receiving box 6 is higher than the material discharging hopper 9 at this time, and the material discharging hopper 9 and the material receiving box 6 are opposite to each other. Then, the second motor 701 drives the drive shaft 703 to rotate, thereby driving the material receiving box 6 to rotate clockwise by a set angle, so that the round steel in the material receiving box 6 rolls down from the material receiving box 6 and falls into the material discharging hopper 9 at the third station. Immediately afterwards, the first air cylinder 1105 extends to push the moving plate 1103 to move towards the right side of the track 1101 on the track 1101, so that the material discharging hopper 9 gradually approaches the conveyor 3 while the height of the material discharging hopper 9 gradually increases. Until after the material discharging hopper 9 moves above the conveyor 3, that is, the material discharging hopper 9 moves to the fourth station, the first air cylinder 1105 pauses working. Immediately afterwards, the second air cylinder 1203 extends so that the curved rod 1202 drives the rotating shaft 302 to rotate clockwise, thereby causing the material discharging hopper 9 to rotate clockwise until the left side of the material discharging hopper 9 is higher than its right side. In this way, the round steel in the material discharging hopper 9 can roll down along the material discharging hopper 9 onto the starting end of the conveyor 3, that is, the fifth station of the conveyor 3. Subsequently, the first air cylinder 1105 shortens to pull the material discharging hopper 9 back to the third station. Then, the second air cylinder 1203 shortens to pull the curved rod 1202 to drive the rotating shaft 302 to rotate counterclockwise, thereby causing the material discharging hopper 9 to rotate counterclockwise, and the material discharging hopper 9 gradually assumes a material receiving state. Finally, the conveyor 3 transports the steel sample from the fifth station to its sixth station, that is, near the laser marking machine.

[0077] It can be seen that the material taking device and the material discharging device 8 are used in cooperation. There is no need for manual sampling by workers. The sampling efficiency of round bars is improved, and it can avoid workers being scalded by round bars during sampling, so the safety performance is improved. Moreover, the sampling device and the material discharging device 8 can automatically place the taken sample onto the conveyor 3, realizing automated sampling and automated material discharging operations. Finally, the conveyor 3 transports the sample to the laser marking machine. Throughout the process, there is no need for manual handling and transfer, which reduces the labor burden of workers and improves production efficiency.

[0078] Optionally, as Figure 9 and Figure 10 shown, a rectangular plate 1106 is installed at the middle position of the connecting pipe 1104. A round hole for the output end of the first air cylinder 1105 to pass through is provided at a position near the bottom of the rectangular plate 1106. External threads are provided on the outer side surface of the output end of the first air cylinder 1105. After the output end of the first air cylinder 1105 passes through the round hole on the rectangular plate 1106, a nut is used to fix the output end of the first air cylinder 1105 to the rectangular plate 1106.

[0079] Optionally, as Figure 6 shown, mounting holes are formed at the top of each support base 1201. Bearings are installed in the mounting holes, and end covers are provided on the outside of the support base 1201 to cover the bearings. Both ends of the rotating shaft are respectively connected in cooperation with the bearings on the two support bases 1201.

[0080] It should be noted that a control box is installed on the mobile cart 4, and the control box controls the entire sampling and unloading action. Specifically, the first motor 511, the second motor 701, the first cylinder 1105 and the second cylinder 1203 are all controlled by the control box to realize programmed sampling and unloading work.
