[0002] At present, during the production process of round bars, when a long round bar enters the cold shear for cutting at the beginning, an operator needs to dial the incoming round bar into the cutting groove of the lower cutter of the cold shear. After that, the round bar is pressed and fixed by the lower pressing roller to complete the shearing process. When the round bar is initially sheared, sampling and marking are required to detect the composition of the round bar and determine whether the composition of the round bar is qualified.

[0003] Currently, it relies on manual use of a long rod to pick up the round bar and then extend it into one end of the cold shear and place it into the first cutting groove of the lower cutter.

[0043] The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. 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.

[0044] As Figure 1 - Figure 29 shown, an embodiment of the present utility model provides a steel production system, including a cold shear 1 and a marking system. The cold shear 1 includes a lower cutting knife and an upper cutting knife. A plurality of first cutting knife grooves are provided on the lower edge of the upper cutting knife, and a plurality of second cutting knife grooves corresponding to the first cutting knife grooves one by one are provided on the upper edge of the lower cutting knife. A set of first cutting knife grooves and second cutting knife grooves cooperate to cut a round bar; a first conveying device, the first conveying device is located on one side of the feeding end of the cold shear 1 and is used to convey the round bar to the feeding end of the cold shear 1. A closing component is installed on the first conveying device, and the closing component is used to close the round bar on the first conveying device to the middle position of the first conveying device; a material distributing device 7, the material distributing device 7 is located above the first conveying device and is used to dial the round bar on the first conveying device into the first cutting knife groove of the lower cutting knife; a second conveying device, one end of the second conveying device is close to the cold shear 1, and the other end is close to the marking system; a sampling and blanking device 15, the sampling and blanking device 15 is used to take out the round bar sample cut in the cold shear 1 and transfer it to the second conveying device; the marking system is used to take down the round bar sample on the second conveying device and mark the round bar sample.

[0045] In this embodiment, the oval bars on the first conveying device enter the feeding end of the cold shear 1 as the first conveying device conveys. Then, the lifting rollers of the cold shear 1 lift one end of the oval bar extending into the cold shear 1, making the right end of the bar higher than the lower cutting knife. Then, the conveying roller table continues to move the bar, making the right end of the bar exceed the lower cutting knife. Then, the material distributing device 7 is used to respectively deflect each bar into a plurality of first cutting knife grooves of the lower cutting knife. Subsequently, the pressing roller mechanism 103 of the cold shear 1 presses down the bar, and then the upper cutting knife moves down to cut the bar, without the need for manual use of a long rod to deflect the bar and respectively pick each bar into the first cutting knife groove of the lower cutting knife. When sampling and marking are required, the sampled bar is taken out of the cold shear 1 by the sampling and blanking device 15 and transferred to the second conveying device. The second conveying device conveys the bar sample to the marking system, and the marking system takes the bar sample on the second conveying device and marks the bar sample.

[0046] It can be seen that this application neither requires manual use of a long rod to deflect the bar and respectively pick each bar into the first cutting knife groove of the lower cutting knife, nor requires manually taking out the bar sample from the cold shear 1 and transferring it to the marking machine. It can automatically deflect the bar into the first cutting knife groove of the lower cutting knife, and can also achieve automatic sampling and marking. The overall work efficiency is greatly improved, the labor intensity is reduced, safety accidents caused by manual material deflection are avoided, and the worker can also be prevented from being scalded by the bar during sampling, greatly improving the safety of the production system.

[0047] It should be noted that, as Figure 1 shown, the first conveying device includes a pedestal 2, a conveying table 101, and a closing assembly. The pedestal 2 and the conveying table 101 are arranged in sequence along the feeding direction of the cold shear 1, that is, the conveying table 101 is located on the left side of the feeding end of the cold shear 1, and the pedestal 2 is located on the left side of the conveying table 101. Conveying roller tables for conveying the bars are provided on both the pedestal 2 and the conveying table 101, and the conveying roller table is composed of a plurality of conveying rollers. Further, the closing assembly includes a first closing mechanism 3, a second closing mechanism 9, and a third closing mechanism 10. The first closing mechanism 3 is installed at the right end face of the pedestal 2, the second closing mechanism 9 is installed at the left end face of the conveying table 101, a groove is provided at the top of the conveying table 101, and the third closing mechanism 10 is installed in the groove at the top of the conveying table 101. The first closing mechanism 3, the second closing mechanism 9, and the third closing mechanism 10 cooperate to close the bars on the first conveying device to the middle position of the first conveying device.

[0048] As Figure 2 and Figure 3As shown in the figure, inside the cold shear 1, there is a workbench 102. The workbench 102 is located at the feeding end on the left side of the cold shear 1. The conveying table 101 is arranged on the left side of the workbench 102 and is closely attached to the workbench 102. At the top of the right side of the conveying table 101, there is an integral raised platform, which is connected to the raised part on the top of the workbench 102, and the upper surface of the raised platform is flush with the upper surface of the raised part on the top of the workbench 102. It should be noted that multiple conveying rollers are arranged on the conveying table 101 along its length direction. A groove adapted to the lifting roller is provided on the upper surface of the raised platform on the right side of the conveying table 101. The cutting tool assembly is located on the right side of the raised part on the top of the workbench 102, and the lower cutting tool is higher than the upper surface of the raised part on the top of the workbench 102. The lower pressing roller mechanism 103 is installed at the left feeding end of the cold shear 1. It should be noted that the conveying table 101, the workbench 102, the lower pressing roller mechanism 103 on the cold shear 1, and the lifting roller on the conveying table 101 are all prior arts.

[0049] It should be particularly noted that in the past, when cutting long round bars, due to the space limitation inside the cold shear 1 and the fact that the conveying roller path on the conveying table 101 cannot be arranged on the workbench 102 because the lifting roller needs to be arranged on the workbench 102, when the long round bar is cut multiple times and only the tail stock remains, at this time, the tail stock falls on the convex platform on the right side of the conveying table 101, and there is no contact between the tail stock and the conveying roller path. The conveying roller path cannot continue to convey the tail stock. Therefore, only workers can use a long rod to extend into the cold shear 1 and push the tail stock so that the tail stock passes through the first cutting tool slot of the lower cutting edge and falls into the waste guide slot of the cold shear 1, resulting in high labor intensity and low work efficiency for workers.

[0050] To solve this problem, as Figure 2 and Figure 3 shown, the steel production system further includes a tail stock pushing device. The tail stock pushing device is used to push the round bar tail stock on the first conveying device into the waste guide slot of the cold shear 1. It includes a support frame assembly, a moving frame 6, a linear driving device 11, and at least one tail stock pushing member;

[0051] Among them, the support frame assembly is arranged on the conveying table 101 to support the moving frame 6. The moving frame 6 is slidably installed on the support frame assembly. The linear driving device 11 is used to drive the moving frame 6 to reciprocate along the conveying direction of the round bar on the support frame assembly. The tail stock pushing member is installed on the moving frame 6;

[0052] The tail stock pushing member has a first state and a second state. When the tail stock pushing member is in the first state, there is a gap for the round bar to pass between the tail stock pushing member and the table top of the conveying table 101. When the tail stock pushing member is in the second state, the end of the tail stock pushing member close to the round bar tail stock is lower than the round bar tail stock;

[0053] When it is necessary to push the end material of the round bar to the waste material chute, the end material pushing member switches to the second state, and the linear driving device 11 drives the moving frame 6 to move towards the waste material chute, so that the end material pushing member pushes the end material of the round bar into the waste material chute of the cold shear machine 1.

[0054] In this way, when cutting the long round bar, the end material pushing member is in the first state. At this time, there is a gap for the round bar to pass between the end material pushing member and the tabletop of the conveying table 101. The long round bar passes through the gap between the end material pushing member and the tabletop of the conveying table 101 and enters the workbench 102 and rests on the workbench 102. When the long round bar is cut multiple times and only the end material remains, at this time the end material pushing member switches to the second state, and the linear driving device 11 is turned on. The linear driving device 11 drives the moving frame 6 to move towards the waste material chute, so that the end material pushing member pushes the end material and makes the end material pass through the first cutting groove of the lower cutting knife and then fall into the waste material chute of the cold shear machine 1. Subsequently, the linear driving device 11 drives the moving frame 6 to move away from the cold shear machine 1 to drive the end material pushing member to withdraw from the cold shear machine 1 and return to the initial position. The end material pushing member switches to the second state to wait for the next end material pushing work.

[0055] Therefore, there is no need for manual use of a long rod to push the end material into the waste material chute, and the automatic end material pushing work can be realized, which saves time and effort, reduces the labor burden of workers, and improves work efficiency.

[0056] As a preferred embodiment, as Figure 3 and Figure 4 shown, the support frame 4 includes a long strip-shaped bearing seat and a plurality of support feet fixedly installed on the lower surface of the bearing seat. The plurality of support feet are fixedly installed on the conveying table 101 and the workbench 102. The long strip-shaped bearing seat is used to support the moving frame 6.

[0057] Furthermore, a guide rail member 5 is installed on each bearing seat. The guide rail member 5 includes a guide rail 501 and a slider 502. The guide rail 501 is installed on the bearing seat, and the guide rail 501 is arranged along the length direction of the bearing seat. A plurality of sliders 502 are slidably installed on each guide rail 501. Both sides of the bottom of the moving frame 6 are fixedly connected to the sliders 502 on the two guide rails 501 at the same time. In this way, pushing the moving frame 6 drives the slider 502 to slide on the guide rail 501 to realize the movement of the moving frame 6 along the length direction of the guide rail 501.

[0058] Furthermore, as Figure 5As shown in the figure, the linear drive device 11 includes two toothed plates 1105, two traveling gears 1104, two rotating shafts 1103, a gearbox 1101, and a first motor 1102. Among them, the two toothed plates 1105 are respectively installed on the bearing seats of the two support frames 4, and the toothed plates 1105 are parallel to the guide rail 501. The gearbox 1101 is fixedly installed on the side of the moving frame 6 away from the cold shear 1. The top of the gearbox 1101 has an input end, and its left and right sides respectively have output ends, and the two output ends are coaxially arranged. For the convenience of distinction, the two rotating shafts 1103 are respectively named the first rotating shaft and the second rotating shaft. Among them, the first rotating shaft is connected to the output end on the left side of the gearbox 1101, and a traveling gear 1104 is installed at the other end of the first rotating shaft. Correspondingly, one end of the second rotating shaft is connected to the output end on the right side of the gearbox 1101, and a traveling gear 1104 is also installed at the other end of the second rotating shaft. The two traveling gears 1104 are respectively engaged with the toothed plates 1105 on the two bearing seats.

[0059] In this way, when the first motor 1102 is turned on, the first rotating shaft and the second rotating shaft are driven to rotate simultaneously through the transmission of the gearbox 1101. The simultaneous rotation of the first rotating shaft and the second rotating shaft drives the two traveling gears 1104 to rotate simultaneously, so that the traveling gears 1104 move along the length direction of the toothed plate 1105, so as to drive the moving frame 6 to move along the length direction of the toothed plate 1105.

[0060] Specifically, as Figure 15 shown, the tail stock pusher includes a frame body 801, a rotating frame 802, and a connecting shaft 803. The frame body 801 includes two rod bodies and a cross bar fixed between the two rod bodies. One ends of the two rod bodies close to the moving frame 6 are detachably connected to the moving frame 6. The other ends of the rod bodies are both installed with connecting seats in a concave shape. The connecting shaft 803 is rotatably installed between the two connecting seats of the two rod bodies. A compression spring 804 is arranged in each connecting seat. The compression spring 804 is sleeved on the connecting shaft 803 to limit the excessive rotation of the connecting shaft 803. The rotating frame 802 is fixedly connected to the connecting shaft 803. It should be noted that the frame body 801 is parallel to the table top of the conveying table 101, and the frame body 801 is higher than the top of the conveying table 101, so that a gap for the round bar to pass through is formed between the frame body 801 and the conveying roller path at the top of the conveying table 101. It should be noted that in the natural state, due to the limitation of the compression spring 804, the rotating frame 802 is connected to the frame body 801 in an inclined state, that is, in the natural state, the rotating frame 802 is not in a vertical state.

[0061] Furthermore, as Figure 5 and Figure 14As shown, on both sides of the top of the conveying table 101, a deflecting member 14 used in cooperation with the tail stock pushing member is installed respectively. The two deflecting members 14 are symmetrically arranged with respect to the conveying table 101. The deflecting member 14 is provided on the top of the conveying table 101 and has a bearing surface. When the tail stock pushing member switches to the first state, the rotating frame 802 is placed on the bearing surface of the deflecting member 14.

[0062] Specifically, as Figure 15 and Figure 16 shown, the deflecting member 14 includes an angle seat 1401 fixed to the side of the top of the conveying table 101 and a guiding plate installed on the inner side wall of the angle seat 1401. Looking from the incoming material direction of the cold shear 1, the angle seat 1401 is L-shaped, which includes a bottom plate and a vertical plate. The bottom plate is fixed to the top of the conveying table 101 by bolts, and the vertical plate is fixedly installed on the bottom plate and perpendicular to the bottom plate. The guiding plate includes an inclined plate 1403 and a horizontal plate 1402 connected to each other. The horizontal plate 1402 is fixedly installed on the side of the vertical plate. One end of the inclined plate 1403 is connected to the surface of the horizontal plate 1402 facing the cold shear 1. The other end of the inclined plate 1403 is lower than the horizontal plate 1402. The included angle formed between the inclined plate 1403 and the horizontal plate 1402 is an obtuse angle. The horizontal plate 1402 is parallel to the conveying table 101 and higher than the conveying roller path. The upper surface of the horizontal plate 1402 forms a bearing surface.

[0063] It should be noted that the height of the lowest position of the inclined plate 1403 is higher than the conveying roller path on the conveying table 101, so that a gap for the round bar to pass through is formed between the lowest position of the inclined plate 1403 and the conveying roller path of the conveying table 101. Since the height of the horizontal plate 1402 is higher than that of the inclined plate 1403, the height difference between the horizontal plate 1402 and the conveying roller path of the conveying table 101 is sufficient for the round bar to pass through.

[0064] Figure 14 The rotating frame 802 on the tail stock pushing member in

[0065] When the linear drive device 11 drives the moving frame 6 to drive the tail stock pusher to move towards the cold shear 1, after the rotating frame 802 disengages from the deflecting member 14, the rotating frame 802 returns to its natural state. At this time, the rotating frame 802 is in an inclined state, that is, the end of the rotating frame 802 far from the frame body 801 is lower than the other end. The height difference between the end of the rotating frame 802 far from the frame body 801 and the conveying table 101 is not enough for the long round bar to pass through. In this way, when the linear drive device 11 drives the moving frame 6 to drive the tail stock pusher to continue to move into the cold shear 1, the bottom end of the rotating frame 802 will eventually push the long round bar to continuously move towards the cold shear 1 on the raised platform on the right side of the conveying table 101, so that the left end of the long round bar tail stock gradually passes through the first cutting groove of the lower cutting knife until the round bar tail stock is pushed into the waste guide groove.

[0066] In this embodiment, when the long round bar is cut many times and only the tail stock remains, at this time, the tail stock is placed on the raised platform on the right side of the conveying table 101 and the raised platform on the top of the workbench 102, and the right end of the tail stock is placed in the first cutting groove of the lower cutting knife. At this time, by starting the first motor 1102, the first rotating shaft and the second rotating shaft are driven to rotate simultaneously through the transmission of the gearbox 1101. The first rotating shaft and the second rotating shaft rotate simultaneously to drive the two traveling gears 1104 to rotate simultaneously, so that the traveling gears 1104 move along the length direction of the toothed plate 1105, so as to drive the moving frame 6 and the tail stock pusher to move towards the cold shear 1 together. When the rotating frame 802 no longer contacts the guide plate, at this time, the rotating frame 802 rotates relative to the frame body 801 under the action of gravity, so that the rotating frame 802 is in an inclined state, that is, the end of the rotating frame 802 far from the frame body 801 is lower than the other end. As the moving frame 6 and the tail stock pusher continue to move towards the cold shear 1, the tail stock pusher gradually approaches and pushes the round bar tail stock to push the long round bar tail stock into the waste guide groove.

[0067] It can be seen that in this embodiment, there is no need for manual use of a long rod to push the long round bar tail stock, and the automatic tail stock pushing work can be realized, greatly improving the work efficiency and saving time and effort.

[0068] Optionally, as Figure 15 and Figure 16 shown, a plurality of fixing pieces 805 are installed inside the rotating frame 802. The plurality of fixing pieces 805 are uniformly arranged along the length direction of the rotating frame 802, and the fixing pieces 805 are fixedly connected to the connecting shaft 803. Further, there is an opening on the side of the rotating frame 802 far from the frame body 801. A round shaft is installed between every two adjacent fixing pieces 805, and a roller 806 is sleeved on each round shaft. The roller 806 is located at the opening on the side of the rotating frame 802 far from the frame body 801.

[0069] In this way, when the rotating frame 802 is no longer in contact with the guide plate 1202, the rotating frame 802 gradually rotates to an inclined state, so that the roller 806 in the rotating frame 802 falls on the raised platform on the right side of the conveying platform 101, and the rotating frame 802 can move on the raised platform to more conveniently push the tailings.

[0070] Optional, such as Figure 14 As shown, the mobile frame 6 includes a frame in the shape of a Chinese character U and a triangular support frame mounted on the top of the Chinese character U frame. Considering that if the length of the remaining round bar tail is relatively long, the tail pusher installed on the right side of the mobile frame 6 may not be able to push. A tail pusher is also installed on the left side of the mobile frame 6.

[0071] like Figure 14 As shown, for the convenience of distinction, the two tail material pushing members are named as the first tail material pushing member 8 and the second tail material pushing member 13 respectively, wherein the first tail material pushing member 8 is installed on the right side of the movable frame 6, and the second tail material pushing member 13 is installed on the left side of the movable frame 6.

[0072] In this way, if the left end of the round rod tail exceeds the first tail pushing member 8, that is, the left end of the round rod tail is located on the left side of the first tail pushing member 8, the first tail pushing member 8 will not work. At this time, the round rod tail can be pushed by the second tail pushing member 13. Of course, a change-over member 14 used in conjunction with the second tail pushing member 13 is also installed on the table of the conveying platform 101.

[0073] It should be noted that in the past, when long round bars were cut, the pedestal 2 and the conveyor rollers on the top of the conveyor platform 101 cooperated to convey the round bars until the end of the round bar facing the cold shear machine 1 was placed on the top protrusion of the workbench 102, and then the lifting roller on the protrusion on the right side of the conveyor platform 101 moved upward to lift the right end of the round bar, so that the right end of the round bar was higher than the lower cutting knife, and then the pedestal 2 and the conveyor rollers on the conveyor platform 101 continued to move the round bar, so that the right end of the round bar exceeded the lower cutting knife, that is, the right end of the round bar moved to the right side of the lower cutting knife, and then the worker used a long rod to move the round bar, so that each round bar was adjusted to the top of each first cutting knife groove on the lower cutting knife, and then the lifting roller moved down, and the right end of each round bar entered into each first cutting knife groove on the cutting knife respectively, and finally the lower pressure roller mechanism 103 pressed down the round bar, and the upper cutting knife moved down to cooperate with the lower cutting knife to cut the round bar. However, the technical solution of manually moving the round bar to the first cutting groove of the lower cutting knife has low working efficiency, and due to the narrow space in the cold shearing machine, there are many safety hazards in manual material shifting, high labor intensity, and easy to cause safety accidents such as mechanical injuries.

[0074] To solve this technical problem, a material distributing device 7 is installed on the moving rack 6. The material distributing device 7 includes a scissors rack mechanism, a bidirectional driving component, and multiple material distributing heads. The material distributing device 7 is installed on the moving rack 6 and can approach or move away from the tabletop of the conveying table 101;

[0075] Preferably, the scissors rack mechanism includes multiple scissors arms. The point where the middle of any one scissors arm is connected to the middle of an adjacent scissors arm forms a first node. The point where the first end of any one scissors arm is connected to the first end of an adjacent scissors arm forms a second node. The point where the second end of any one scissors arm is connected to the second end of an adjacent scissors arm forms a third node. A material distributing head is installed at the bottom of each first node. The bidirectional driving component is used to drive the two ends of the scissors rack mechanism to approach or move away from each other.

[0076] In this embodiment, the conveying roller path at the top of the conveying table 101 conveys the round bars until one end of the round bar facing the cold shear machine 1 rests on the protrusion at the top of the workbench 102. Then the closing component closes the round bars so that multiple round bars are brought together towards the middle position of the tabletop of the conveying table 101. The multiple round bars enter the predetermined position. At this time, each material distributing head at the first node is respectively located directly above the gaps between the multiple round bars. Then the lifting roller moves upward to lift the right end of the round bar so that the right end of the round bar is higher than the lower cutting knife. Then the material distributing device 7 approaches the tabletop of the conveying table 101 to reduce the height of the scissors rack mechanism, so that multiple material distributing heads on the scissors rack mechanism are simultaneously inserted into the gaps between the round bars. Subsequently, the bidirectional driving component drives the two ends of the scissors rack mechanism to move away from each other, and any two symmetric first nodes on the scissors rack mechanism also move away from each other accordingly, thereby simultaneously driving the material distributing heads on any two symmetric first nodes to move away from each other. Finally, multiple material distributing heads simultaneously move outward to push multiple round bars to move outward simultaneously, so that the gap between any two adjacent round bars is adjusted to the set value. At this time, the multiple round bars just move directly above the multiple first cutting grooves of the lower cutting knife. Subsequently, the material distributing device 7 moves away from the tabletop of the conveying table 101, so that the material distributing heads are withdrawn from the gaps between the two round bars. Then the lifting roller moves downward, and the right ends of each round bar respectively enter the first cutting grooves on the cutting knife. Finally, the pressing roller mechanism 103 presses down on the round bar, and the upper cutting knife moves downward to cooperate with the lower cutting knife to cut the round bar.

[0077] It can be seen that in this embodiment, there is no need for manual use of a long rod to stir the round bars to pick each round bar into the first cutting groove of the lower cutting knife respectively. The working efficiency is greatly improved, the labor intensity is reduced, the safety accidents caused by manual material feeding are avoided, and the safety is improved.

[0078] It should be noted that as Figure 13As shown in the figure, the scissors lift mechanism includes a plurality of scissors forks in an X shape, and the plurality of scissors forks are sequentially hinged. The scissors fork includes a first scissors arm 726 and a second scissors arm 727. The middle parts of the first scissors arm 726 and the second scissors arm 727 in the scissors fork are hinged. A first hinge plate 724 and a second hinge plate 725 are formed on the left side of the scissors lift mechanism. One end of the first hinge plate 724 is hinged to one end of the second hinge plate 725. The other end of the first hinge plate 724 is hinged to one end of the first scissors arm 726 in the adjacent scissors fork. The other end of the second hinge plate 725 and one end of the second scissors arm 727 in the adjacent scissors fork are hinged. On the right side of the scissors lift mechanism, there are a third hinge plate 728 and a fourth hinge plate 729. Among them, one end of the third hinge plate 728 is hinged to one end of the fourth hinge plate 729. The other end of the third hinge plate 728 and one end of the first scissors arm 726 in the adjacent scissors fork are hinged. The other end of the fourth hinge plate 729 and one end of the second scissors arm 727 in the adjacent scissors fork are hinged.

[0079] Further, the point where the middle parts of the first scissors arm 726 and the second scissors arm 727 in the scissors fork are hinged forms a first node. Figure 13 Taking the direction into the paper as the top view direction, first angles are respectively formed on the left and right sides of the first scissors arm 726 and the second scissors arm 727 in each scissors fork, and second angles are respectively formed on the front and back sides of the first scissors arm 726 and the second scissors arm 727 in each scissors fork. The first angle is an obtuse angle, and the second angle is an acute angle.

[0080] In this embodiment, a material distributing head is installed at the bottom of each first node. After the plurality of material distributing heads on the scissors lift mechanism are simultaneously inserted into the gaps between the round bars, the two-way driving device drives the two ends of the scissors lift mechanism to move away from each other. The angle of the first angle between the first scissors arm 726 and the second scissors arm 727 in any scissors fork gradually decreases while the second angle gradually increases, that is, the distance between two adjacent scissors forks gradually increases, so that any two symmetric first nodes on the scissors lift mechanism also move away from each other accordingly, thereby simultaneously driving the material distributing heads on any two symmetric first nodes to move away from each other. Finally, the plurality of material distributing heads move outward simultaneously to push the plurality of round bars to move outward simultaneously, so that the gap between any two adjacent round bars is adjusted to a set value, thereby playing a role in uniformly pushing the round bars to both sides, so that each round bar can just move into the first cutting groove of each lower cutting knife.

[0081] Preferably, as Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12As shown, the material distribution device 7 includes a main shaft 702, two side plates 701 and two connecting plates 703. The bidirectional drive assembly includes a bidirectional threaded rod 705, a drive device, a first threaded sleeve 718, a first moving sleeve, a fixed sleeve and a second threaded sleeve 721.

[0082] Among them, as Figure 7 shown, the main shaft 702 is rotatably installed on the moving frame 6, and the main shaft 702 is arranged along the width direction of the conveying table 101, that is, the length direction of the main shaft 702 is perpendicular to the conveying direction of the conveying roller path on the conveying table 101. The same ends of the two side plates 701 are fixedly installed at both ends of the main shaft 702, and the two connecting plates 703 are respectively fixedly installed at the ends of the two side plates 701 away from the main shaft 702. The bidirectional threaded rod 705 is rotatably installed between the two connecting plates 703, and the drive device is installed on one side plate 701, and the drive device is used to drive the bidirectional threaded rod 705 to rotate around its own axis.

[0083] Further, as Figure 10 shown, the fixed sleeve is fixed along the axial position of the middle part of the bidirectional threaded rod 705 relative to the bidirectional threaded rod 705. There is no thread in the middle part of the bidirectional threaded rod 705, and threads with opposite directions are provided at both ends thereof. The first threaded sleeve 718 and the second threaded sleeve 721 are respectively screwed on both ends of the bidirectional threaded rod 705. A plurality of first moving sleeves are respectively arranged between the first threaded sleeve 718 and the fixed sleeve and between the second threaded sleeve 721 and the fixed sleeve. The first moving sleeves are slidably installed on the bidirectional threaded rod 705. Along the axial direction of the bidirectional threaded rod 705, the left and right ends of the scissors mechanism are respectively hinged to the first threaded sleeve 718 and the second threaded sleeve 721, that is, the hinge point of the first hinge plate 724 and the second hinge plate 725 in the scissors mechanism is connected to the top surface of the first threaded sleeve 718, and the hinge point of the third hinge plate 728 and the fourth hinge plate 729 in the scissors mechanism is connected to the top surface of the second threaded sleeve 721. A plurality of first nodes of the scissors mechanism are sequentially connected between the first moving sleeves between the first threaded sleeve 718 and the fixed sleeve, the fixed sleeve and the first moving sleeves between the fixed sleeve and the second threaded sleeve 721. A material distribution head is provided at the bottom of each of the first threaded sleeve 718, the first moving sleeve, the fixed sleeve and the second threaded sleeve 721.

[0084] Further, as Figure 10As shown, locking columns are screwed onto the tops of the first threaded sleeve 718, the first moving sleeve, the fixed sleeve, and the second threaded sleeve 721. A ring is coaxially provided at the top of each locking column. When installing the scissors mechanism onto the first threaded sleeve 718, the first moving sleeve, the fixed sleeve, and the second threaded sleeve 721, first place the scissors mechanism on the first threaded sleeve 718, the first moving sleeve, the fixed sleeve, and the second threaded sleeve 721, and align the round hole at the connection of the first hinge plate 724 and the second hinge plate 725 with the threaded hole on the first threaded sleeve 718, align multiple first nodes on the scissors mechanism with the threaded holes on the first moving sleeve and the fixed sleeve at the same time, and align the round hole at the connection of the third hinge plate 728 and the fourth hinge plate 729 with the threaded hole on the second threaded sleeve 721. Then, sequentially tighten multiple locking columns into the threaded holes on the first threaded sleeve 718, the threaded holes on the first moving sleeve between the first threaded sleeve 718 and the fixed sleeve, the threaded holes on the fixed sleeve, the threaded holes on the first moving sleeve between the fixed sleeve and the second threaded sleeve 721, and the threaded holes on the second threaded sleeve 721 respectively.

[0085] When the driving device drives the bidirectional threaded rod 705 to rotate around its own axis, since the thread directions at both ends of the bidirectional threaded rod 705 are opposite, the first threaded sleeve 718 and the second threaded sleeve 721 are driven to move towards both sides simultaneously, causing the scissors mechanism to gradually unfold towards both sides at the same time. As the scissors mechanism gradually unfolds towards both sides at the same time, the first moving sleeve between the first threaded sleeve 718 and the fixed sleeve drives the material distribution head on the first moving sleeve to move towards one side, and the first moving sleeve between the second threaded sleeve 721 and the fixed sleeve drives the material distribution head to move towards the other side, causing the gap between adjacent material distribution heads to gradually increase, thereby playing a role in adjusting the distance between adjacent round bars to move each round bar to directly above the first cutting groove of the lower cutter.

[0086] It should be noted that a bearing is connected in cooperation with the middle of the bidirectional threaded rod 705, and the fixed sleeve is coaxially arranged on the bearing. In this way, when the bidirectional threaded rod 705 rotates, the fixed sleeve will not rotate accordingly, so that the axial position of the fixed sleeve relative to the middle of the bidirectional threaded rod 705 is fixed along the axis of the bidirectional threaded rod 705.

[0087] Furthermore, in this embodiment, as Figure 10 and Figure 11 shown, there are three first moving sleeves between the first threaded sleeve 718 and the fixed sleeve, and there are also three first moving sleeves respectively arranged between the second threaded sleeve 721 and the fixed sleeve. That is, there are a total of 7 first nodes.

[0088] Since the material distributing heads are only installed on the lower surfaces of the first threaded sleeve 718, the first moving sleeve, the fixed sleeve and the second threaded sleeve 721, the actual number of round bars that can be toggled is small. To further enhance the efficiency of the material distributing device 7 so that more round bars can be toggled onto the corresponding first cutting grooves of the lower cutter simultaneously.

[0089] Preferably, as Figure 9 , Figure 10 , Figure 11 and Figure 12 shown, among any two adjacent scissor forks of the scissor frame mechanism, the point where the first end of the first scissor arm 726 of the first scissor fork is hinged to the first end of the second scissor arm 727 of the second scissor fork is the second node, and the point where the second end of the second scissor arm 727 in the first scissor fork is hinged to the second end of the first scissor arm 726 in the second scissor fork is the third node. That is, the second node and the third node are respectively located on both sides of the width direction of the scissor frame mechanism, and the first node is located between the second node and the third node. As Figure 8 shown, the second node is located on the right side of the third node, that is, the second node is closer to the cold shearer 1.

[0090] Furthermore, as Figure 8 shown, the material distributing device 7 further includes a first sliding rod 706, a second sliding rod 707, a plurality of second moving sleeves 719 and a plurality of third moving sleeves 720. Among them, a first limiting hole 714 and a second limiting hole 715 are respectively formed in each connecting plate 703. The length directions of the first limiting hole 714 and the second limiting hole 715 are perpendicular to the axial direction of the bidirectional threaded rod 705, that is, the length directions of the first limiting hole 714 and the second limiting hole 715 are consistent with the length direction of the conveying table 101. Both ends of the first sliding rod 706 are slidably installed between the first limiting holes 714 of the two connecting plates 703. Both ends of the second sliding rod 707 are respectively slidably installed between the second limiting holes 715 of the two connecting plates 703. And the first sliding rod 706 is located on the right side of the bidirectional threaded rod 705, the second sliding rod 707 is located on the left side of the bidirectional threaded rod 705. The axes of the first sliding rod 706, the second sliding rod 707 and the bidirectional threaded rod 705 are located in the same horizontal plane.

[0091] Furthermore, a plurality of second moving sleeves 719 are slidably installed on the first sliding rod 706, a plurality of third moving sleeves 720 are slidably installed on the second sliding rod 707, and a material distributing head is installed at the bottom of each second moving sleeve 719. To distinguish this material distributing head from the material distributing head on the above-mentioned first node, this material distributing head is named the second material distributing head 717, and the material distributing heads at the bottoms of the first threaded sleeve 718, the first moving sleeve, the fixed sleeve and the second threaded sleeve 721 are named the first material distributing head 716. Combining Figure 11 and Figure 12, multiple second nodes are sequentially connected to the second moving sleeve 719, and multiple third nodes of the scissors mechanism are sequentially connected to multiple third moving sleeves 720. Further, the hinge point between the second hinge plate 725 and the adjacent scissor fork is connected to the second moving sleeve 719, the hinge point between the first hinge plate 724 and the adjacent scissor fork is connected to the third moving sleeve 720, the hinge point between the third hinge plate 728 and the adjacent scissor fork is connected to the second moving sleeve 719, and the hinge point between the fourth hinge plate 729 and the adjacent scissor fork is connected to the third moving sleeve 720.

[0092] When the bidirectional threaded rod 705 rotates, it will first drive the first threaded sleeve 718 and the second threaded sleeve 721 to move towards both sides respectively. Since the fixed sleeve is axially stationary relative to the bidirectional threaded rod 705, as the first threaded sleeve 718 and the second threaded sleeve 721 move towards both sides simultaneously, the scissors mechanism gradually unfolds towards both sides at the same time. The angle of the first included angle in each scissor fork gradually decreases, and the second included angle gradually increases, thereby pulling the first sliding rod 706 and the second sliding rod 707 closer to each other. As the scissors mechanism gradually unfolds towards both sides at the same time, the first moving sleeve between the first threaded sleeve 718 and the fixed sleeve drives the first material distributing head 716 on the first moving sleeve to move towards the first side. At the same time, several second moving sleeves 719 on one side of the first sliding rod 706 drive the second material distributing head 717 to also move towards the first side. And the first moving sleeve between the second threaded sleeve 721 and the fixed sleeve drives the first material distributing head 716 to move towards the second side. Several second moving sleeves 719 on the other side of the first sliding rod 706 drive the second material distributing head 717 to move towards the second side. Eventually, the gap between adjacent first material distributing heads 716 reaches the set value, and the gap between adjacent second material distributing heads 717 reaches the set value. In this way, the first material distributing head 716 and the second material distributing head 717 can simultaneously push each round bar outwards, so as to simultaneously dial more round bars and improve production efficiency.

[0093] Optionally, a material distributing head is installed at the bottom of each third moving sleeve 720, and at this time, no material distributing head is installed at the bottom of the second moving sleeve 719.

[0094] Preferably, as Figure 4 、 Figure 6 and Figure 8As shown in the figure, a carrying rail 12 is installed on the inner side of each of the two support frames 4. The carrying rail 12 is arranged along the conveying direction of the conveying roller path. The carrying rail 12 includes a straight rail and a bending part 1201 that are connected in sequence. The bending part 1201 is located at the right end of the straight rail, that is, the bending part 1201 is closer to the cold shear 1. One end of the bending part 1201 away from the straight rail is lower than the straight rail. A gap for the round bar to pass through is formed between the straight rail and the conveying roller path. One end of the bending part 1201 away from the straight rail is lower than the height of the round bar on the conveying table 101. Further, at least one walking wheel 712 is installed at the bottom of each of the two side plates 701. The walking wheels 712 on the two side plates 701 slide on the carrying rail 12 respectively.

[0095] When the round bar moves, at this time, the moving frame 6 is higher than the round bar. The side plate 701 of the material distribution device 7 is placed on the straight rail of the carrying rail 12. Since the gap between the straight rail and the tabletop of the conveying table 101 is sufficient for the round bar to pass through, the material distribution device 7 is higher than the round bar. As the round bar moves on the conveying table 101 along with the conveying roller path on the conveying table 101 to the workbench 102, the lifting roller moves upward to lift the right ends of multiple round bars, so that the right ends of multiple round bars are higher than the lower cutting knife. Then the conveying roller path continues to drive the round bar to move to the right until the right end of the round bar exceeds the lower cutting knife. Then the closing assembly closes multiple round bars towards the middle position of the conveying table 101, so that multiple round bars move to the set position. Subsequently, the moving frame 6 drives the material distribution device 7 to move to the right. The material distribution device 7 slides on the straight rail. When the material distribution device 7 moves to the bending part 1201, the main shaft 702 in the material distribution device 7 rotates naturally relative to the moving frame 6, thereby driving the side plate 701, the bidirectional threaded rod 705, the scissors frame mechanism, etc. to rotate. The scissors frame mechanism gradually approaches the round bar, so that multiple first material distribution heads 716 and multiple second material distribution heads 717 are inserted into the gaps between the round bars at the same time. Subsequently, when the bidirectional threaded rod 705 rotates, it will drive the first threaded sleeve 718 and the second threaded sleeve 721 to move towards both sides respectively. Since the fixed sleeve is axially stationary relative to the bidirectional threaded rod 705, as the first threaded sleeve 718 and the second threaded sleeve 721 move towards both sides at the same time respectively, the scissors frame mechanism gradually unfolds towards both sides at the same time. The angle of the first included angle in each scissors fork gradually decreases, and the second included angle gradually increases, thereby pulling the first sliding rod 706 and the second sliding rod 707 closer to each other. As the scissors frame mechanism gradually unfolds towards both sides at the same time, finally the gap between adjacent first material distribution heads 716 reaches the set value, and the gap between adjacent second material distribution heads 717 reaches the set value, thereby pushing multiple round bars towards both sides at the same time, and finally making the gap between adjacent two round bars reach the set value. At this time, each round bar is respectively located directly above each first cutting knife groove of the lower cutting knife. Subsequently, the moving frame 6 moves to the left to drive the material distribution device 7 to withdraw from the bending part 1201 and move to the straight rail. Then the pressing roller presses down the round bar, and the upper cutting knife moves downward to cut the round bar short.

[0096] It can be seen that in this embodiment, the shearing work of the round bars can be automatically completed, without the need for manual use of a long rod to move the round bars one by one and pick them into the first cutter groove of the lower cutter, greatly improving the work efficiency, reducing the labor intensity, avoiding safety accidents caused by manual feeding, and improving the safety performance.

[0097] Preferably, as Figure 7 and Figure 8 shown, a bearing 713 is respectively installed on two connecting plates 703, and both ends of the bidirectional threaded rod 705 are respectively connected to the two bearings 713. The driving device includes a main gear 708, a transmission gear 709, a fixed gear 710 and a driving motor 711. Among them, the fixed gear 710 is fixedly installed at one end of the bidirectional threaded rod 705. A transmission gear 709 and a fixed gear 710 are successively rotatably installed on one side plate 701. The main gear 708, the transmission gear 709 and the fixed gear 710 are successively meshed. The driving motor 711 is fixedly installed on the side plate 701, and the output end of the driving motor 711 is connected to the main gear 708 for driving the main gear 708 to rotate around its axis.

[0098] Optionally, in order to protect the scissor frame mechanism and the material dividing head, as Figure 9 shown, a protective cover 704 is installed between the two connecting plates 703.

[0099] Optionally, in order to further enhance the stability of the material dividing device 7 during material dividing, as Figure 11 and Figure 12 shown, two scissor frame mechanisms are provided. Among them, the first scissor frame mechanism 722 is located above the first threaded sleeve 718, the first moving sleeve, the second moving sleeve 719, the third moving sleeve 720 and the second threaded sleeve 721, and the second scissor frame mechanism 723 is located below the first threaded sleeve 718, the first moving sleeve, the second moving sleeve 719, the third moving sleeve 720 and the second threaded sleeve 721.

[0100] Preferably, as Figure 12 shown, the material dividing head is integrally cylindrical, and its bottom is sharp, so as to be inserted into the gap between the round bars.

[0101] Preferably, the first closing mechanism 3, the second closing mechanism 9 and the third closing mechanism 10 are respectively used to close the round bars from the tail end, the middle end and the head end of the round bars, so as to stably close the round bars towards the middle position of the conveying table 101. Specifically, the structures of the first closing mechanism 3 and the second closing mechanism 9 are the same, and both include two cylinders. The two cylinders of the first closing mechanism 3 are symmetrically arranged with respect to the pedestal 2 and are installed at the right end face of the pedestal 2. The two cylinders of the second closing mechanism 9 are symmetrically arranged with respect to the conveying table 101 and are installed at the left end face of the conveying table 101.

[0102] AsFigure 18 As shown in the figure, the third closing mechanism 10 includes a support base 1001, guide rails 1002, sliding seats 1003, vertical frames 1004, rotating cylinders 1005, vertical seats 1006, two threaded rods 1007, and a second motor 1008. The support base 1001 is fixedly installed in the groove on the tabletop of the conveying table 101. A fixed platform is installed at the middle position of the support base 1001. Two guide rails 1002 are fixedly installed on both sides of the top of the support base 1001. A sliding seat 1003 is slidably installed on each guide rail 1002. A vertical seat 1006 is fixedly installed at both ends of the top of the support base 1001. A threaded rod 1007 is rotatably installed between the first vertical seat 1006 and the fixed platform, and a threaded rod 1007 is rotatably installed between the second vertical seat 1006 and the fixed platform. The thread directions of these two threaded rods 1007 are opposite, and these two threaded rods 1007 are connected by a coupling. A vertical frame 1004 is fixedly installed on the top of each sliding seat 1003. The output end of the second motor 1008 is fixedly connected to one end of a threaded rod 1007. Further, a rotating cylinder 1005 is rotatably installed on each vertical frame 1004. Specifically, a rotating cylinder 1005 is installed on the right side of the vertical frame 1004 on the left side of the support base 1001, and a rotating cylinder 1005 is installed on the left side of the vertical frame 1004 on the right side of the support base 1001. Each rotating cylinder 1005 is vertically arranged.

[0103] The second motor 1008 drives the two threaded rods 1007 to rotate simultaneously. Since the thread directions of these two threaded rods 1007 are opposite, the two sliding seats 1003 are driven to drive the two vertical frames 1004 to approach or move away from each other. When the two vertical frames 1004 approach each other, the rotating cylinders 1005 on the two vertical frames 1004 simultaneously push the round bars on the conveying table 101 from the left and right sides of the conveying table 101.

[0104] It should be noted that during traditional manual sampling, due to the narrow space inside the cold shearer 1, there are many potential safety hazards during sampling, and safety accidents such as mechanical injuries are likely to occur. To solve this technical problem, as Figure 1 shown, a sampling and blanking device 15 including a sampling device and a blanking device 21 is arranged beside the cold shearer 1. The sampling device has a first working position and a second working position. The blanking device 21 has a third working position and a fourth working position. The second conveying device has a fifth working position and a sixth working position. The fifth working position is located at the starting end of the second conveying device, and the sixth working position is located at the terminal of the second conveying device; the second working position is adjacent to the third working position, and the fourth working position is adjacent to the fifth working position; where:

[0105] When the sampling device is in the first working position, the sampling device is used to receive the cut round bar samples in the cold shearing machine 1; when the sampling device is in the second working position, the sampling device is used to turn out the taken round bar samples into the blanking device 21 in the third working position;

[0106] When the blanking device 21 is in the third working position, the blanking device 21 is used to receive the round bar samples turned out by the sampling device; when the blanking device 21 is in the fourth working position, the blanking device 21 is used to turn out the round bar samples to the fifth working position of the second conveying device, and the second conveying device is used to convey the round bar samples at the fifth working position to the sixth working position;

[0107] During sampling, in this embodiment, the first working position of the sampling device is inside the cold shearing machine 1, the second working position of the sampling device is outside the cold shearing machine 1 and close to the third working position of the blanking device 21, the fifth working position of the second conveying device is close to the fourth working position of the blanking device 21, and the sixth working position of the second conveying device is close to the laser marking machine 2802.

[0108] When sampling and transporting the round bar, first, the sampling device in the first working position receives the cut round bar samples in the cold shearing machine 1, then the sampling device switches to the second working position, and the sampling device in the second working position turns out the taken round bar samples into the blanking device 21 in the third working position. After that, the blanking device 21 switches to the fourth working position to turn out the round bar samples to the fifth working position of the second conveying device, and the second conveying device conveys the round bar samples at the fifth working position to the sixth working position for the marking system to perform marking.

[0109] In this application, the sampling device and the blanking device 21 are used for sampling, eliminating the need for manual sampling. The sampling efficiency of the round bar is improved, and the risk of workers being scalded by the round bar during sampling is avoided, enhancing the safety performance. Moreover, the sampling device cooperates with the blanking device 21 to place the taken samples on the second conveying device, eliminating the need for manual handling and transfer, reducing the labor burden of workers, and improving the production efficiency.

[0110] Among them, the second conveying device is the conveyor 16, and the specific type is not limited, such as a belt conveyor or a roller conveyor.

[0111] Preferably, the sampling and blanking device 15 further includes a mobile trolley 17. A carrying frame 1702 is installed on the mobile trolley 17, a push handle 1701 is installed at the front of the mobile trolley 17, the sampling device is installed on the carrying frame 1702, and the blanking device 21 is installed on the mobile trolley 17. The mobile trolley 17 can be used to move the sampling device and the blanking device 21, ensuring the flexibility of the sampling and blanking device 15 for sampling the round bars in other cold shearing machines 1.

[0112] As a preferred embodiment, as Figure 19As shown, the sampling device includes a linear drive assembly 18, a material receiving box 19, and a first flipping mechanism 20. When the linear drive assembly 18 is in the first working state, the linear drive assembly 18 drives the material receiving box 19 to extend downward along a first direction under the cutting tool assembly of the cold shearing machine 1 to receive the cut round bar; when the linear drive assembly 18 is in the second working state, the linear drive assembly 18 drives the material receiving box 19 to move along a second direction to withdraw from the cold shearing machine 1; the first direction and the second direction are opposite to each other, and the first direction is perpendicular to the conveying direction of the conveying table 101. Specifically, as Figure 1 shown, the first end of the linear drive assembly 18 extends into the cold shearing machine 1, and its second end is located outside the cold shearing machine 1. The first direction is the direction from the second end to the first end of the linear drive assembly 18, and the second direction is the direction from the first end to the second end of the linear drive assembly 18.

[0113] Furthermore, the first flipping mechanism 20 is installed on the linear drive assembly 18 and is connected to the material receiving box 19. When the first flipping mechanism 20 is in the flipping mode, the first flipping mechanism 20 drives the material receiving box 19 to flip to turn out the round bar in the material receiving box 19 and fall into the blanking device 21 at the third working station; when the first flipping mechanism 20 is in the reset mode, the first flipping mechanism 20 drives the material receiving box 19 to return to the upright position.

[0114] In this way, when taking the material, first, the linear drive assembly 18 drives the material receiving box 19 to move in the direction close to the cold shearing machine 1 and extend downward under the cutting tool assembly of the cold shearing machine 1, and the cut steel falls into the material receiving box 19. Then, the linear drive assembly 18 drives the material receiving box 19 to move in the direction 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 20 is adjusted to the flipping mode, so as to drive the material receiving box 19 to flip to turn out the steel in the material receiving box 19 and fall into the blanking device 21 at the third working station. Finally, the first flipping mechanism 20 switches to the reset mode to drive the material receiving box 19 to return to the upright position for the next sampling work. Through the mutual cooperation of the linear drive assembly 18, the material receiving box 19, and the first flipping mechanism 20, the automatic sampling work is realized. The whole sampling work is convenient, fast, time-saving and labor-saving.

[0115] Preferably, as Figure 20 shown, the linear drive assembly 18 includes a housing 1801, a sliding plate 1802, and a driving mechanism. The housing 1801 is in the shape of a slender long box. The sliding plate 1802 is slidably installed on the side surface of the housing 1801. The driving mechanism is installed in the housing 1801 to drive the sliding plate 1802 to move along the length direction of the housing 1801. The first flipping mechanism 20 is installed on the sliding plate 1802, and one end of the first flipping mechanism 20 is connected to the material receiving box 19 to drive the material receiving box 19 to rotate. Furthermore, as Figure 19As shown, the outer shell 1801 is detachably mounted on the bearing frame 1702 such that the length direction of the outer shell 1801 is consistent with the length direction of the bearing frame 1702.

[0116] During sampling, the mobile trolley 17 can be pushed so that the end of the outer shell 1801 in the linear drive assembly 18 extends into the cold shear 1 and approaches one side of the lower tool block of the cutter assembly. Subsequently, the drive mechanism drives the sliding plate 1802 to drive the material receiving box 19 to move towards the cold shear 1, so that the material receiving box 19 extends into the interior of the cold shear 1. The upper cutter in the cutter assembly cooperates with the lower tool block to cut the round bar, and the cut round bar falls into the material receiving box 19. As the drive mechanism drives the sliding plate 1802 to drive the material receiving box 19 to move away from the cold shear 1, the material receiving box 19 exits the cold shear 1 and retracts to its original position.

[0117] As a preferred embodiment, in this embodiment, as Figure 21 shown, the drive mechanism includes a driving sprocket 1809, a driven sprocket 1810, a chain, and a third motor 1811. Among them, the driving sprocket 1809 and the driven sprocket 1810 are sequentially rotatably mounted in the outer shell 1801 along the length direction of the outer shell 1801. Specifically, the driving sprocket 1809 is rotatably mounted at one end of the outer shell 1801 away from the cold shear 1, and the driven sprocket 1810 is rotatably mounted at one end of the outer shell 1801 close to the cold shear 1. The chain is transmission-mounted between the driving sprocket 1809 and the driven sprocket 1810. The third motor 1811 is fixedly mounted on the side surface of the outer shell 1801, and the output end of the third motor 1811 is connected to the driving sprocket 1809. Further, the sliding plate 1802 is slidably mounted on the right side surface of the outer shell 1801, and a part of the sliding plate 1802 is connected to the chain. Again Figure 20 shown, the first flipping mechanism 20 is mounted on the sliding plate 1802 and is connected to the material receiving box 19.

[0118] When the drive mechanism drives the sliding plate 1802 to move along the length direction of the outer shell 1801, the third motor 1811 drives the driving sprocket 1809 to rotate. Since the chain is transmission-mounted between the driving sprocket 1809 and the driven sprocket 1810, the chain rotates. Also, since the sliding plate 1802 is connected to the chain, the sliding plate 1802 moves along the length direction of the outer shell 1801 as the chain rotates, and the material receiving box 19 moves with the movement of the sliding plate 1802.

[0119] As an alternative embodiment, in order to ensure that the sliding plate 1802 can slide stably on the outer shell 1801 and reduce the friction between the sliding plate 1802 and the outer shell 1801, an upper hole body and a lower hole body are successively formed along the length direction on the front panel 1812 on the right side of the outer shell 1801. 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 strip holes, and the lengths of the upper hole body and the lower hole body are slightly smaller than the length of the front panel 1812, and the upper hole body is located above the lower hole body. Further, a first bearing rail 1803 is installed on the inner bottom wall of the upper hole body, and a second bearing rail 1804 is installed on the inner bottom wall of the lower hole body. The first bearing rail 1803 and the second bearing rail 1804 are exactly the same, and the length of the first bearing rail 1803 is slightly smaller than the length of the upper hole body.

[0120] Further, as Figure 22 and Figure 23 shown, a first wheel body 1813 and a second wheel body 1815 are installed on the back surface of the sliding plate 1802. The first wheel body 1813 is located above the second wheel body 1815. The distance between the first bearing rail 1803 and the second bearing rail 1804 is the same as the distance between the first wheel body 1813 and the second wheel body 1815. When installing the sliding plate 1802, the first wheel body 1813 on the back surface of the sliding plate 1802 can be installed on the first bearing rail 1803, and at the same time, the second wheel body 1815 can be installed on the second bearing rail 1804.

[0121] It should be noted that the cross-sections of the first bearing rail 1803 and the second bearing rail 1804 are convex-shaped. Both the first wheel body 1813 and the second wheel body 1815 include a shaft body and wheel rims on both sides of the shaft body. The inner walls of the two wheel rims on the first wheel body 1813 are attached to both sides of the top of the first bearing rail 1803, and the inner walls of the two wheel rims on the second wheel body 1815 are attached to both sides of the top of the second bearing rail 1804. In this way, the friction between the sliding plate 1802 and the outer shell 1801 can be changed into rolling friction, reducing the frictional force and improving the moving efficiency. Second, the roller cannot be separated from the bearing rail, so as to hold the sliding plate 1802 and prevent the sliding plate 1802 from separating from the outer shell 1801.

[0122] Optionally, as Figure 23 shown, a connecting member 1814 is installed on the back surface of the sliding plate 1802. The connecting member 1814 is at the same height as the first wheel body 1813, and the connecting member 1814 is used to connect with a chain.

[0123] In order to facilitate pouring out the round bar samples in the material receiving box 19 and pouring the round bar samples onto the blanking device 21. Preferably, as Figure 5As shown in the figure, a first flipping mechanism 20 is installed on the front of the sliding plate 1802. The first flipping mechanism 20 includes a fourth motor 2001, a coupling 2002, and a drive shaft 2003. Among them, the fourth motor 2001 is fixedly installed on the front of the sliding plate 1802 through an L-shaped angle seat. A rectangular frame is fixedly installed on the front of the sliding plate 1802. Bearings are installed on both sides of the left side of the rectangular frame. The drive shaft 2003 passes through the two bearings. One end of the drive shaft 2003 close to the fourth motor 2001 is connected to the output end of the fourth motor 2001 through the coupling 2002. One end of the drive shaft 2003 close to the material receiving box 19 is detachably connected to the material receiving box 19 through a flange member.

[0124] In this way, when it is necessary to pour out the round bars in the material receiving box 19, the fourth motor 2001 drives the coupling 2002 and the drive shaft 2003 to rotate, and finally drives the material receiving box 19 to rotate together to turn out the round bars in the material receiving box 19.

[0125] In order to better detect whether the material receiving box 19 extends to the set position of the cold shear 1, as Figure 20 shown, a proximity switch 1808 is installed on the top of the end of the outer shell 1801 extending into the cold shear 1, and a signal trigger 1807 is installed at the top position on the front of the sliding plate 1802. In this way, when the sliding plate 1802 drives the material receiving box 19 to move towards the inside of the cold shear 1 to the set position, at this time the signal trigger 1807 just moves to the proximity switch 1808, and the proximity switch 1808 quickly issues an electrical command, and the controller controls the third motor 1811 to pause so that the material receiving box 19 can just receive all the cut round bars.

[0126] Optionally, as Figure 3 shown, a drag chain carrier frame 1805 for accommodating the drag chain 1806 is installed on the top of the outer shell 1801 along its length direction. A drag chain connecting piece in the shape of an inverted L-shaped plate is installed on the sliding plate 1802. One end of the drag chain 1806 in the drag chain carrier frame 1805 is connected to the drag chain connecting piece. The drag chain 1806 is used to induct signal wires.

[0127] In order to automatically place the round bar samples in the material receiving box 19 onto the conveyor 16, a blanking device 21 is specially installed on the right side of the moving trolley 17. The blanking device 21 receives the round bar samples in the material receiving box 19 and places the round bar samples onto the conveyor 16. As Figure 24As shown, the blanking device 21 includes a blanking hopper 22, a second flipping mechanism 25, and a linear moving mechanism 24; the linear moving mechanism 24 includes a track mechanism and a power device. The track mechanism is inclined and lower than the receiving box 19. The first end of the track mechanism is close to the receiving box 19 and the first end of the track mechanism is lower than its second end; both the blanking hopper 22 and the second flipping mechanism 25 are slidably mounted on the track mechanism;

[0128] When the blanking hopper 22 is in the third working position, the blanking hopper 22 is located at the first end of the track mechanism; when the blanking hopper 22 is in the fourth working position, the blanking hopper 22 is located at the second end of the track mechanism; the power device is used to drive the blanking hopper 22 to switch between the third working position and the fourth working position;

[0129] The second flipping mechanism 25 has a first working state and a second working state. When the second flipping mechanism 25 is in the first working state, the second flipping mechanism 25 drives the blanking hopper 22 in the fourth working position to flip so as to turn out the round bars in the blanking hopper 22 onto the fifth working position of the conveyor 16; when the second flipping mechanism 25 is in the second working state, the second flipping mechanism 25 drives the blanking hopper 22 in the third working position to return to the upright position to receive the round bar samples turned out by the receiving box 19.

[0130] Specifically, when the blanking hopper 22 is in the third working position, the blanking hopper 22 is located at the first end of the track mechanism. At this time, the blanking hopper 22 is located below the receiving box 19 and is used to carry the round bar samples turned out by the receiving box 19. The power device can drive the blanking hopper 22 to switch between the third working position and the fourth working position, so as to drive the blanking hopper 22 to gradually approach the conveyor 16 and its height is also continuously increasing. Finally, the blanking hopper 22 is moved to the second end of the track mechanism. At this time, the blanking hopper 22 is close to the fifth working position of the conveyor 16 and is higher than the fifth working position of the conveyor 16. Then, the second flipping mechanism 25 drives the blanking hopper 22 in the fourth working position to flip so as to turn out the steel in the blanking hopper 22 onto the fifth working position of the conveyor 16, and then the conveyor 16 conveys the steel at the fifth working position to the sixth working position of the conveyor 16. At the same time, the power device drives the blanking hopper 22 in the fourth working position to switch to the third working position, so that the blanking hopper 22 is moved to the first end of the track mechanism. Then, the second flipping mechanism 25 drives the blanking hopper 22 in the third working position to return to the upright position to continue receiving the round bar samples turned out by the receiving box 19. Therefore, the blanking device 21 in this embodiment plays a role in transporting and transferring the round bar samples, so as to smoothly transfer the round bar samples to the conveyor 16, without the need for manual handling of the round bar samples in the receiving box 19 to the conveyor 16, improving the production efficiency.

[0131] Such as Figure 24As shown, a notch is formed at the middle position on the right side of the mobile trolley 17. Plate bodies are respectively fixed on the two inner walls before and after the notch. A bracket assembly 23 is installed between the two plate bodies, and a linear movement mechanism 24 is installed on the bracket assembly 23. Specifically, as Figure 25 and Figure 27 shown, the bracket assembly 23 includes two support plates 2301 and two fixing rods 2302. The two support plates 2301 are right-angled triangular plates. The two support plates 2301 are respectively fixed on the two plate bodies in the notch by bolts, and the inclined surfaces of the support plates 2301 face upward, that is, from the left side to the right side of the mobile trolley 17, the left end of the support plate 2301 is lower than its right end. The two fixing rods 2302 are fixedly installed between the two support plates 2301 to connect the two support plates 2301 and enhance the stability of the bracket assembly 23.

[0132] As Figure 25 shown, the linear movement mechanism 24 includes a first cylinder 2404, two moving plates 2403, and a connecting pipe 2405. Among them, the track mechanism includes two tracks 2401, and the power device includes a first cylinder 2404. The two tracks 2401 are respectively fixedly installed on the top inclined surfaces of the two support plates 2301 so that the tracks 2401 are inclined. Two translation seats 2402 are slidably installed on each track 2401, and the two translation seats 2402 on each track 2401 are connected by a moving plate 2403. The top of the translation seat 2402 is fixedly connected to the moving plate 2403. One end of the connecting pipe 2405 is fixed to the right end of one moving plate 2403, and the other end is fixed to the right end of the other moving plate 2403.

[0133] Furthermore, as Figure 10 shown, the first cylinder 2404 is installed on a fixing rod 2302 through a mounting seat, and the other end is connected to the connecting pipe 2405. The feeding hopper 22 is rotatably installed between the two moving plates 2403, and a second flipping mechanism 25 is installed on one moving plate 2403 to drive the feeding hopper 22 to flip.

[0134] When the receiving box 19 in the sampling device retracts to the set position, the receiving box 19 is aligned with the blanking hopper 22 at this time. After that, the first cylinder 2404 extends to push the connecting pipe 2405. Since the two moving plates 2403 are fixed by the connecting pipe 2405, and the moving plates 2403 are slidably mounted on the track 2401 through the translation seats 2402, when the first cylinder 2404 extends, it will push the moving plates 2403 to move to the right side of the track 2401 on the track 2401. The blanking hopper 22 is installed between the two moving plates 2403, so it will also move to the right side of the track 2401, so that the blanking hopper 22 gradually approaches the conveyor 16, and the height of the blanking hopper 22 gradually increases until the blanking hopper 22 moves above the conveyor 16, or the right side of the blanking hopper 22 is above the conveyor 16. After that, the second flipping mechanism 25 drives the blanking hopper 22 to rotate to adjust the inclination angle of the blanking hopper 22, so that the left side of the blanking hopper 22 is high and the right side is low, so that the round bars in the blanking hopper 22 will smoothly roll from the blanking hopper 22 onto the conveyor 16. Such a transfer has high efficiency, is convenient to operate, and saves time and effort.

[0135] As a preferred embodiment, as Figure 26 shown, the second flipping mechanism 25 includes a flipping shaft, two platform seats 2501, a curved rod 2502, a second cylinder 2503 and a hinge seat 2504. Among them, the two platform seats 2501 are respectively installed on the two moving plates 2403. The platform seats 2501 are in the shape of inclined plates, and the included angle formed between the platform seats 2501 and the moving plates 2403 is an acute angle. The hinge seat 2504 is installed on the moving plate 2403 in front of the blanking hopper 22. The first end of the curved rod 2502 is connected to the flipping shaft, one end of the second cylinder 2503 is hinged to the hinge seat 2504, and the other end is hinged to the second end of the curved rod 2502. The bottom of the blanking hopper 22 is fixedly connected to the flipping shaft.

[0136] In this way, as the driving mechanism drives the sliding plate 1802 to drive the receiving box 19 to move away from the cold shear 1, the receiving box 19 is withdrawn from the cold shear 1 and retracts to the original position, that is, the receiving box 19 is in the second working position and retracts to as Figure 19The state shown, at this time the material receiving box 19 is higher than the blanking hopper 22, and the blanking hopper 22 and the material receiving box 19 are opposite to each other. Then the fourth motor 2001 drives the drive shaft 2003 to rotate, thereby driving the material receiving box 19 to rotate clockwise by a set angle, so that the round bar in the material receiving box 19 rolls out of the material receiving box 19 and falls into the blanking hopper 22 at the third station. Immediately afterwards, the first cylinder 2404 extends to push the moving plate 2403 to move to the right on the track 2401, so that the blanking hopper 22 gradually approaches the conveyor 16 while the height of the blanking hopper 22 gradually increases. Until the blanking hopper 22 moves above the conveyor 16, that is, the blanking hopper 22 moves to the fourth station, the first cylinder 2404 pauses working. Immediately afterwards, the second cylinder 2503 extends so that the curved rod 2502 drives the turning shaft to rotate clockwise, thereby causing the blanking hopper 22 to rotate clockwise until the left side of the blanking hopper 22 is higher than its right side, so that the round bar in the blanking hopper 22 can roll down along the blanking hopper 22 onto the starting end of the conveyor 16, that is, the fifth station of the conveyor 16. Subsequently, the first cylinder 2404 shortens to pull the blanking hopper 22 back to the third station, and then the second cylinder 2503 shortens to pull the curved rod 2502 to drive the turning shaft to rotate counterclockwise, thereby causing the blanking hopper 22 to rotate counterclockwise, and the blanking hopper 22 gradually assumes a material receiving state. Finally, the conveyor 16 conveys the round bar sample from the fifth station to its sixth station, that is, near the laser marking machine 2802.

[0137] It can be seen that the material taking device and the blanking device 21 are used in cooperation. There is no need for manual sampling, the sampling efficiency of the round bar is improved, and it can avoid workers being scalded by the round bar during sampling, so the safety performance is improved. Moreover, the sampling device cooperates with the blanking device 21 to automatically place the taken sample on the conveyor 16, realizing automatic sampling and automatic blanking operations. Finally, the conveyor 16 conveys the sample to the marking system. Throughout the process, there is no need for manual handling and transfer, which reduces the labor burden of workers and improves production efficiency.

[0138] Optionally, as Figure 26 shown, a rectangular plate 2406 is installed at the middle position of the connecting pipe 2405. A round hole for the output end of the first cylinder 2404 to pass through is provided near the bottom of the rectangular plate 2406. An external thread is provided on the outer side surface of the output end of the first cylinder 2404. After the output end of the first cylinder 2404 passes through the round hole on the rectangular plate 2406, a nut is used to fix the output end of the first cylinder 2404 to the rectangular plate 2406.

[0139] Optionally, as Figure 6 shown, mounting holes are formed at the top ends of each platform seat 2501. Bearings are installed in the mounting holes, and end covers are provided on the outside of the platform seat 2501 to cover the bearings. Both ends of the turning shaft are respectively connected to the bearings on two platform seats 2501 in a matching manner.

[0140] As shown Figure 28 in the figure, the marking system includes an identification component 26, a grasping component 27, and a marking component 28. The identification component 26 is used to identify and position the round bar sample at the terminal of the second conveying device to obtain the position information of the round bar sample. The grasping component 27 grabs the round bar sample at the terminal of the second conveying device according to the position information sent by the identification component 26 and places it on the marking component 28. The marking component 28 is used to mark the round bar sample.

[0141] The sampled and cut round bar sample is taken out from the cold shearer 1 by the sampling and blanking device 15 and placed at the starting end of the conveyor 16. The round bar sample moves with the conveyor 16 and stops after reaching the terminal position of the conveyor 16. Then, the identification component 26 identifies and positions the round bar sample to obtain the position information of the round bar sample. The grasping component 27 grabs the round bar sample at the terminal of the conveyor 16 according to the position information sent by the identification component 26 and places it at the designated position of the marking component 28. The marking is carried out by the marking component 28. The entire sampling and marking process does not require manual participation, fully realizes automation, does not require manual sampling, does not require manual handling and transfer of round bars, improves the sampling efficiency, can avoid workers being scalded by round bars during sampling, improves the safety performance, reduces the labor burden of workers, and improves the production efficiency.

[0142] As a preferred embodiment, as Figure 28 shown in the figure, a detection area is formed at the terminal of the conveyor 16, and a first sensor module is installed in the detection area. The identification component 26 is arranged on the right side of the terminal of the conveyor 16, that is, on the right side of the sixth working station of the conveyor 16. The identification component 26 includes a mounting frame 2601 and an identification camera 2602. The identification camera 2602 is installed on the top of the mounting frame 2601, and the identification camera 2602 is located directly above the terminal of the conveyor 16. The identification camera 2602 is aligned with the detection area to obtain the position information of the steel sample in the detection area. The first sensor module is used to detect whether the steel sample enters the detection area at the terminal of the conveyor 16; the control module controls the opening and closing of the conveyor 16 according to the signal input by the first sensor module.

[0143] Specifically, the first sensor module can be any one of an infrared sensor and a proximity switch, as long as it can detect the steel sample entering the detection area. A control box is installed beside the conveyor 16, and the control box has a PLC control module, a signal receiving unit, a signal sending unit, etc.

[0144] Furthermore, as Figure 29 shown in the figure, the grasping component 27 is arranged at the back position of the terminal of the conveyor 16, the marking component 28 is arranged on the left side of the grasping component 27, and a plurality of storage boxes 29 for loading round bar samples are placed on the right side of the marking component 28.

[0145] Specifically, as Figure 29 shown, the grasping assembly 27 includes a rotating base 2701, a robotic arm 2702, and a fixture 2703. The robotic arm 2702 is installed on the rotating base 2701, and the fixture 2703 is detachably installed at the connecting end of the robotic arm 2702. Among them, the fixture 2703 is a common electromagnetic fixture for grasping round bars, which will not be elaborated here.

[0146] When the round bar on the conveyor 16 is conveyed to the detection area at the terminal of the conveyor 16, the first sensor module monitors that the round bar sample enters the detection area and sends a detection signal to the signal receiving unit of the control box. The PLC control module controls the conveyor 16 to pause operation so that the identification camera 2602 can identify. After the identification camera 2602 identifies the round bar sample in the detection area and obtains the position and attitude information of the round bar sample. The PLC control module controls the robotic arm 2702 in the grasping assembly 27 to drive the fixture 2703 to grasp the round bar sample in the detection area and place it on the marking assembly 28. During this process, the fixture 2703 does not release the round bar sample. After the marking is completed, the PLC control module controls the robotic arm 2702 in the grasping assembly 27 to drive the fixture 2703 to place the marked round bar sample on the storage box 29. It should be noted that the position information of the storage box 29 is pre-entered into the control box, so that the marked round bar sample can be smoothly placed into the storage box 29.

[0147] Furthermore, the marking assembly 28 includes a marking table 2801 and a laser marking machine 2802. The tabletop of the marking table 2801 is the marking area, and the laser marking machine 2802 is installed on the marking table 2801, and the laser head of the laser marking machine 2802 is directly facing the marking area.

[0148] Optionally, a second sensor module is installed at the starting end of the conveyor 16. The second sensor module is an infrared sensor, which is used to detect whether there is a round bar sample at the starting end of the conveyor 16. The PLC control module controls the opening and closing of the conveyor 16 according to the signal input by the second sensor module. In this way, only when the steel sample enters the conveyor 16, the PLC control module will control the conveyor 16 to start. In other cases, the conveyor 16 is in a normally closed state to save power. It can be seen that in this embodiment, the automatic marking work of the round bar sample can be realized, without manual marking, reducing the labor burden of workers and having high production efficiency.

[0149] In summary, the steel production system can automatically move the round bars on the first conveying device into the first cutting tool groove of the lower cutting tool, eliminating the need for manual feeding. It can also automatically perform the tail pushing operation for the tail materials, eliminating the need for manual pushing of the round bar tail materials into the waste material guiding groove. Moreover, it can automatically take out the cut round bar samples in the cold shear machine 1 and transport them to the marking system, eliminating the need for manual sampling. This improves the round bar sampling efficiency and can prevent workers from being scalded by the round bars during sampling, enhancing the safety performance. Finally, it realizes the automated marking work, greatly improving the overall work efficiency, reducing the labor intensity, and significantly enhancing the safety of the production system.
