Description

Technical Field

[0001] The utility model relates to the technical field of steel production, in particular to a steel tail material pushing device and a steel production cutting system. Background Art

[0002] In the process of round bar production and manufacturing, a roller conveyor for conveying steel is usually arranged at the feeding end of a cold shear. One end of a long round bar close to the cold shear falls on the roller conveyor. As the roller conveyor runs, the long round bar gradually approaches the cold shear and then enters the cold shear. Subsequently, the operator needs to dial the incoming round bar into the shearing groove of the lower shear blade of the cold shear.

[0003] Since the roller conveyor cannot extend into the cold shear, as the long round bar is continuously sheared by the cold shear, the remaining tail material stays in the shearing groove of the lower shear blade of the cold shear. At this time, the worker needs to hold a long rod to push the round bar tail material to push it into the waste guide groove. Due to the limited on-site space and the heavy tail material, it is very troublesome and time-consuming for the worker to hold the long rod to push the tail material manually. Summary of the Utility Model

[0004] (1) The problem to be solved by the utility model is that as the long round bar is continuously sheared by the cold shear, the remaining tail material stays in the shearing groove of the lower shear blade of the cold shear. At this time, the worker needs to hold a long rod to push the round bar tail material to push it into the waste guide groove. Due to the limited on-site space and the heavy tail material, it is very troublesome and time-consuming for the worker to hold the long rod to push the tail material manually.

[0005] (2) Technical Solution

[0006] A steel tail material pushing device is installed on a conveying table near the feeding end of a cold shear. The steel tail material pushing device is used to push the steel tail material on the conveying table into the waste guide groove of the cold shear, and includes a support frame assembly, a moving frame, a linear driving assembly and at least one tail material pushing member;

[0007] The support frame assembly is arranged on the conveying table to support the moving frame. The moving frame is slidably installed on the support frame assembly, and the tail material pushing member is installed on the moving frame;

[0008] The linear driving assembly is used to drive the moving frame to drive the tail material pushing member to move along a first direction to push the steel tail material into the waste guide groove of the cold shear, or drive the moving frame to drive the tail material pushing member to move along a second direction to retreat to the initial position. The first direction and the second direction are two directions with opposite directions.

[0009] According to an embodiment of the present utility model, the tail stock pusher includes a frame body and a rotating frame. One side of the frame body away from the cold shear is connected to the moving frame, and a gap for the steel to pass through is formed between the frame body and the top of the conveying table. The rotating frame is hinged to one side of the frame body facing the cold shear.

[0010] According to an embodiment of the present utility model, the steel tail stock pushing device includes at least one deflecting member cooperating with the tail stock pusher. The deflecting member is arranged on the side surface of the conveying table and is used to change the inclination angle of the rotating frame relative to the conveying table to adjust the height difference between the rotating frame and the top of the conveying table.

[0011] According to an embodiment of the present utility model, the deflecting member includes an angle seat fixed to the top of the conveying table and a guiding plate mounted on the angle seat. The guiding plate includes a connected inclined plate and a horizontal plate. The horizontal plate is parallel to the conveying table and higher than the conveying table. One end of the inclined plate is connected to the surface of the horizontal plate facing the cold shear, and the other end of the inclined plate is lower than the horizontal plate. An obtuse angle is formed between the inclined plate and the horizontal plate. A gap for the steel to pass through is formed between the end of the inclined plate away from the horizontal plate and the top of the conveying table; when the tail stock pusher moves in the second direction to retreat to the initial position, the rotating frame rests on the horizontal plate.

[0012] According to an embodiment of the present utility model, one side of the rotating frame away from the frame body has an opening, and a plurality of rollers are sequentially rotatably installed in the opening.

[0013] According to an embodiment of the present utility model, a rotating shaft is rotatably installed on one side of the frame body close to the rotating frame. One side of the rotating frame close to the frame body is fixedly connected to the rotating shaft, and a driving motor is installed on the side of the rotating frame. The output end of the driving motor is connected to one end of the rotating shaft.

[0014] According to an embodiment of the present utility model, the support frame assembly includes two support frames, which are respectively installed on opposite sides of the conveying table, and the two support frames are symmetrically arranged with respect to the conveying table. A guide rail mechanism is installed on each support frame along its length direction, and the moving frame is installed on the two guide rail mechanisms. The moving frame can move in the first direction or the second direction on the guide rail mechanism.

[0015] According to an embodiment of the present utility model, the linear driving assembly includes two toothed plates, two traveling gears, two driving shafts, a gear box and a motor. The two toothed plates are respectively installed on the two support frames;

[0016] The gearbox is fixedly installed on the moving frame. The gearbox has an input end and two output ends. The two output ends of the gearbox are coaxially arranged. The input end of the motor is connected to the input end of the gearbox. The two output ends of the gearbox are respectively connected to the two drive shafts. One walking gear is installed at one end of each of the two drive shafts away from the gearbox. The two walking gears are respectively engaged with the two toothed plates.

[0017] According to an embodiment of the present invention, there are two tail stock pushing members. The two tail stock pushing members are sequentially installed on the moving frame along the first direction. Two sets of deflecting members for cooperating with the two tail stock pushing members are sequentially arranged on the conveying table along the first direction.

[0018] A steel production cutting system includes the above-mentioned steel tail stock pushing device.

[0019] The beneficial effects of the present invention:

[0020] A steel tail stock pushing device provided by the present invention is installed on the conveying table near the feeding end of the cold shear. The steel tail stock pushing device is used to push the steel tail stock on the conveying table into the waste guide groove of the cold shear, and includes a support frame assembly, a moving frame, a linear driving assembly and at least one tail stock pushing member;

[0021] The support frame assembly is arranged on the conveying table to support the moving frame. The moving frame is slidably installed on the support frame assembly, and the tail stock pushing member is installed on the moving frame; the linear driving assembly is used to drive the moving frame to drive the tail stock pushing member to move along the first direction to push the steel tail stock into the waste guide groove of the cold shear, or drive the moving frame to drive the tail stock pushing member to move along the second direction to retreat to the initial position. The first direction and the second direction are two directions with opposite directions.

[0022] When cutting a long round bar, the tail stock pushing member is in the first state. At this time, there is a gap for the steel to pass between the tail stock pushing member and the tabletop of the conveying table. The long round bar passes through the gap between the tail stock pushing member and the tabletop of the conveying table and enters the cold shear. When the long round bar is cut multiple times and only the tail stock remains, at this time the tail stock pushing member switches to the second state, and then the linear driving assembly is turned on. The linear driving assembly drives the moving frame to move towards the waste guide groove direction, so that the tail stock pushing member pushes the tail stock and makes the tail stock pass through the shearing groove of the lower shear blade and fall into the waste guide groove of the cold shear. Subsequently, the linear driving assembly drives the moving frame to move away from the cold shear to drive the tail stock pushing member to withdraw from the cold shear and return to the initial position. The tail stock pushing member switches to the second state to wait for the next tail stock pushing work.

[0023] It can be seen that there is no need for manual use of a long rod to push the tail material into the waste chute, and the automatic tail material pushing work can be realized, which saves time and effort, reduces the labor burden of workers, and improves work efficiency.

Detailed implementation mode

[0035] The technical solutions 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.

[0036] Embodiment 1:

[0037] As Figures 1 - 9 shown, Embodiment 1 of the present utility model provides a steel tailing pushing device. The steel tailing pushing device 2 is installed on the conveyor table 101 near the feeding end of the cold shearing machine 1. The steel tailing pushing device 2 is used to push the steel tailings on the conveyor table 101 into the waste chute of the cold shearing machine 1, and includes a support frame assembly, a moving frame 8, a linear drive assembly 9 and at least one tailing pusher;

[0038] The support frame assembly is arranged on the conveyor table 101 to support the moving frame 8. The moving frame 8 is slidably installed on the support frame assembly, and the tailing pusher is installed on the moving frame 8;

[0039] The linear drive assembly 9 is used to drive the moving frame 8 to drive the tailing pusher to move in the first direction to push the steel tailings into the waste chute of the cold shearing machine 1, or drive the moving frame 8 to drive the tailing pusher to move in the second direction to retreat to the initial position. The first direction and the second direction are two directions with opposite directions.

[0040] Specifically, in this embodiment, the first direction is the incoming material direction of the cold shearing machine 1, or the conveying direction of the conveyor table 101.

[0041] It should be noted that the cold shearing machine 1 has a workbench 102 inside, and the workbench 102 is located at the feed end on the left side of the cold shearing machine 1. The conveying platform 101 is arranged on the left side of the workbench 102 and is close to the workbench 102. An integrated raised platform 103 is arranged on the top of the right side of the conveying platform 101, and the raised platform 103 is connected to the raised platform 104 on the top of the workbench 102, and the upper surface of the raised platform 103 is flush with the upper surface of the raised platform 104 on the top of the workbench 102. A plurality of conveying rollers are arranged on the conveying platform 101 along its length direction, and a groove matching the lifting roller is provided on the upper surface of the raised platform 103 on the right side of the conveying platform 101. The cutter assembly is located on the right side of the raised platform 104 on the top of the workbench 102, and the lower cutter is higher than the upper surface of the raised platform 104 on the top of the workbench 102. A lower pressure roller mechanism 105 is installed at the left feed end of the cold shearing machine 1.

[0042] In the past, the conveyor roller on the top of the conveyor table 101 conveyed the round bar until the end of the round bar facing the cold shearing machine 1 was placed on the top protrusion 104 of the workbench 102, and then the lifting roller 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 cutter. Then the conveyor roller continued to move the round bar so that the right end of the round bar exceeded the lower cutter, that is, the right end of the round bar moved to the right side of the lower cutter. 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 cutter groove on the lower cutter, and then the lifting roller was lowered. The upper cutter moves downward to cooperate with the lower cutter to cut the round bar for the first time, and then the lower pressure roller mechanism 105 releases the long round bar, and then the conveyor roller on the conveyor platform 101 drives the long round bar to move the set distance and then stop, and then the lower pressure roller mechanism 105 presses down the round bar, and the upper scissors in the cold shear machine 1 cut down again to cut the long round bar for the second time, and then repeat the above process to cut the long round bar multiple times. However, due to space limitations and the need to install a lifting roller on the raised platform 103, the conveyor roller cannot be set on the raised platform 103. This will cause a problem, that is, when the long round bar is cut multiple times and only the tail is left, the left end of the tail rests on the raised platform 103 and the raised platform 104, and the right end rests in the shearing groove of the lower shear blade. At this time, the tail is not in contact with the conveyor roller, and the conveyor roller cannot continue to convey the tail. Therefore, it can only be done manually by using a long rod to reach into the cold shear machine 1 and push the tail, so that the tail passes through the shearing groove of the lower shear blade and falls into the waste guide groove of the cold shear machine 1.

[0043] In this embodiment, when cutting the long round bar, the tail stock pusher is in the first state. At this time, there is a gap for the steel to pass between the tail stock pusher and the tabletop of the conveying table 101, and the long round bar enters the cold shear 1 through the gap between the tail stock pusher and the tabletop of the conveying table 101. When the long round bar is cut multiple times and only the tail stock remains, the tail stock pusher switches to the second state at this time. Then, the linear drive assembly 9 is activated, and the linear drive assembly 9 drives the moving frame 8 to move towards the waste chute direction, so that the tail stock pusher pushes the tail stock and makes the tail stock fall into the waste chute of the cold shear 1 through the shear groove of the lower shear blade. Subsequently, the linear drive assembly 9 drives the moving frame 8 to move away from the cold shear 1 to drive the tail stock pusher to withdraw from the cold shear 1 and return to the initial position, and the tail stock pusher switches to the second state to wait for the next tail stock pushing operation.

[0044] It can be seen that in this embodiment, there is no need for manual use of a long rod to push the tail stock into the waste chute, and the automatic tail stock pushing work can be realized, which saves time and effort, reduces the labor burden of workers, and improves work efficiency.

[0045] In this embodiment, a roller conveyor is installed on the conveying table 101. The roller conveyor includes a plurality of rollers for conveying, and a plurality of roller grooves for accommodating the rollers are opened along the length direction of the tabletop of the conveying table 101.

[0046] As a preferred embodiment, as Figure 2 、 Figure 3 and Figure 4 shown, the support frame assembly includes two support frames 6, and the two support frames 6 are respectively installed on the front and back of the conveying table 101. The support frame 6 includes a strip-shaped bearing seat and a plurality of support feet fixedly installed on the lower surface of the bearing seat. The support feet are fixedly installed on the conveying table 101. The strip-shaped bearing seat is used to support the moving frame 8, and the cross-section of the bearing seat is concave, and the top of the bearing seat has a receiving cavity.

[0047] Furthermore, a guide rail mechanism 7 is installed on each bearing seat. The guide rail mechanism 7 includes a guide rail 701 and a slider 702. The guide rail 701 is installed in the receiving cavity of the bearing seat, and the guide rail 701 is arranged along the length direction of the bearing seat. A plurality of sliders 702 are slidably installed on each guide rail 701, and both sides of the bottom of the moving frame 8 are fixedly connected to the sliders 702 on the two guide rails 701 at the same time. In this way, by pushing the moving frame 8 to drive the slider 702 to slide on the guide rail 701, the moving frame 8 can be moved along the length direction of the guide rail 701.

[0048] As a preferred embodiment, as Figure 5 and Figure 6As shown in the figure, the linear drive assembly 9 includes two toothed plates 901, two traveling gears 906, two drive shafts, a gearbox 903, and a motor 902. The two toothed plates 901 are respectively installed on the bearing seats of the two support frames 6, and the toothed plates 901 are parallel to the guide rail 701.

[0049] Further, as Figure 6 shown in the figure, the gearbox 903 is fixedly installed on the side of the moving frame 8 away from the cold shear 1. The top of the gearbox 903 has an input end, and its left and right sides respectively have output ends. The two output ends are coaxially arranged. For the convenience of distinction, the two drive shafts are respectively named the first drive shaft 904 and the second drive shaft 905. Among them, the first drive shaft 904 is connected to the output end on the left side of the gearbox 903, and a traveling gear 906 is installed at the other end of the first drive shaft 904. Correspondingly, one end of the second drive shaft 905 is connected to the output end on the right side of the gearbox 903, and a traveling gear 906 is also installed at the other end of the second drive shaft 905. The two traveling gears 906 are respectively engaged with the toothed plates 901 on the two bearing seats.

[0050] In this way, when the motor 902 is started, the first drive shaft 904 and the second drive shaft 905 are driven to rotate simultaneously through the transmission of the gearbox 903. The first drive shaft 904 and the second drive shaft 905 rotate simultaneously to drive the two traveling gears 906 to rotate simultaneously, so that the traveling gears 906 move along the length direction of the toothed plate 901, so as to drive the moving frame 8 to move along the length direction of the toothed plate 901, so that the moving frame 8 drives the tail stock pusher to extend into or withdraw from the cold shear 1.

[0051] Preferably, the tail stock pusher is installed on the side of the moving frame 8 facing the cold shear 1. Specifically, the tail stock pusher includes a frame body 1001, a rotating frame 1002, and a rotating shaft 1003. The frame body 1001 includes two rod bodies and a fixing rod fixed between the two rod bodies. One ends of the two rod bodies close to the moving frame 8 are

[0052] detachably connected to the moving frame 8. Concave-shaped connecting seats are installed at the other ends of the rod bodies. The rotating shaft 1003 is rotatably installed between the two connecting seats of the two rod bodies. A compression spring 1004 is arranged in each connecting seat. The compression spring 1004 is sleeved on the rotating shaft 1003 to limit the rotation of the rotating shaft 1003. The rotating frame 1002 is fixedly connected to the rotating shaft 1003. It should be noted that the frame body 1001 is parallel to the table top of the conveying table 101, and the frame body 1001 is higher than the top of the conveying table 101, so that a gap for the steel to pass through is formed between the frame body 1001 and the rollers at the top of the conveying table 101.

[0053] It should be noted that in the natural state, due to the limitation of the compression spring 1004, the rotating frame 1002 is connected to the frame 1001 in an inclined state, that is, in the natural state, the rotating frame 1002 is not in a vertical state.

[0054] Furthermore, as Figure 5 and Figure 6 shown, on both sides of the top of the conveying table 101, there are respectively installed a deflecting member that cooperates with the tail stock pushing member. The two deflecting members are symmetrically arranged with respect to the conveying table 101. The deflecting member is used to change the inclination angle of the rotating frame 1002 relative to the conveying table 101 to adjust the height difference between the rotating frame 1002 and the top rollers of the conveying table 101.

[0055] Specifically, as Figure 7 shown, the deflecting member includes an angle seat 12 fixed to the side of the top of the conveying table 101 and a guide plate 1202 installed on the inner side wall of the angle seat 12. Looking from the incoming material direction of the cold shear 1, the angle seat 12 is L-shaped, which includes a bottom plate and a vertical plate. The bottom plate is fixed to the side of 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 guide plate 1202 includes a connected inclined plate and a horizontal plate. The horizontal plate is fixedly installed on the side of the vertical plate, one end of the inclined plate is connected to the side of the horizontal plate facing the cold shear 1, and the other end of the inclined plate is lower than the horizontal plate. The included angle formed between the inclined plate and the horizontal plate is an obtuse angle.

[0056] It should be noted that the height of the lowest position of the inclined plate is higher than the top rollers of the conveying table 101, so that a gap for the steel to pass through is formed between the lowest position of the inclined plate and the top rollers of the conveying table 101. Since the height of the horizontal plate is higher than that of the inclined plate, the height difference between the horizontal plate and the top rollers of the conveying table 101 is sufficient for the steel to pass through.

[0057] Figure 3 In the initial state, the steel tail stock pushing device 2 is in the initial state. At this time, the rotating frame 1002 on the tail stock pushing member is placed on the horizontal plate of the deflecting member. Since the height difference between the horizontal plate and the top rollers of the conveying table 101 is sufficient for the long round bar to pass through, the tail stock pushing member will not affect the movement of the long round bar towards the cold shear 1, and the long round bar smoothly passes through the bottom of the rotating frame 1002.

[0058] When the linear drive assembly 9 drives the moving frame 8 to drive the tail stock pusher to move towards the cold shear 1, after the rotating frame 1002 disengages from the deflecting member, the rotating frame 1002 returns to its natural state. At this time, the rotating frame 1002 is in an inclined state, that is, the end of the rotating frame 1002 away from the frame body 1001 is lower than the other end. At this time, the height difference between the end of the rotating frame 1002 away from the frame body 1001 and the conveying table 101 is not enough for the long round bar to pass through. When the linear drive assembly 9 drives the moving frame 8 to drive the tail stock pusher to continue moving into the cold shear 1, the bottom end of the rotating frame 1002 will finally push the long round bar and push the tail stock of the long round bar out of the shearing groove of the lower shear blade, so that the round bar tail stock is pushed into the waste guide groove.

[0059] In this embodiment, when cutting the long round bar, the steel tail stock pushing device 2 is in the initial state at this time, that is Figure 3 the state shown in the figure. At this time, the frame body 1001 in the tail stock pusher is higher than the long round bar, and the rotating frame 1002 in the tail stock pusher is placed on the horizontal plate of the deflecting member, that is, the rotating frame 1002 is also higher than the long round bar. Therefore, the long round bar can pass through the bottom of the frame body 1001 and the rotating frame 1002. As the long round bar is cut multiple times and only the tail stock remains, at this time, the left end of the tail stock falls on the raised platform 103 of the conveying table 101 and the protrusion 104 of the workbench 102, and its right end falls into the shearing groove of the lower shear blade. At this time, by starting the motor 902, the first drive shaft 904 and the second drive shaft 905 are driven to rotate simultaneously through the transmission of the gearbox 903. The simultaneous rotation of the first drive shaft 904 and the second drive shaft 905 drives the two traveling gears 906 to rotate simultaneously, so that the traveling gears 906 move along the length direction of the toothed plate 901, so as to drive the moving frame 8 and the tail stock pusher to move towards the cold shear 1 together. When the rotating frame 1002 no longer contacts the guide plate 1202, the rotating frame 1002 returns to its natural state at this time. Specifically, the rotating frame 1002 is in an inclined state, that is, the end of the rotating frame 1002 away from the frame body 1001 is lower than the other end. As the moving frame 8 and the tail stock pusher continue to move into the cold shear 1, the tail stock pusher gradually approaches and fits against the end of the long round bar tail stock and then pushes the long round bar tail stock out of the shearing groove of the lower shear blade, so that the round bar tail stock is pushed into the waste guide groove.

[0060] 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 being more time-saving and labor-saving.

[0061] Optionally, as Figure 7 and Figure 8As shown, a plurality of connecting pieces 1006 are installed inside the rotating frame 1002. The plurality of connecting pieces 1006 are evenly arranged along the length direction of the rotating frame 1002, and the connecting pieces 1006 are fixedly connected to the rotating shaft 1003. Further, there is an opening on the side of the rotating frame 1002 away from the frame body 1001. A round shaft is installed between every two adjacent connecting pieces 1006, and a roller 1005 is sleeved on each round shaft. The roller 1005 is located at the opening on the side of the rotating frame 1002 away from the frame body 1001.

[0062] In this way, when the rotating frame 1002 no longer contacts the guide plate 1202, the rotating frame 1002 gradually rotates to an inclined state, so that the roller 1005 in the rotating frame 1002 falls on the tabletop of the conveying table 101. In this way, the rotating frame 1002 can move on the tabletop of the conveying table 101 to more conveniently push the tail material.

[0063] Preferably, as Figure 5 and Figure 6 shown, the moving frame 8 includes a frame in a shape of a Chinese character 'hui' and a triangular support frame mounted on the top of the 'hui'-shaped frame. The 'hui'-shaped frame includes a first cross bar 801 and a second cross bar 802 that are parallel to each other. The first cross bar 801 is close to the cold shear 1, and the second cross bar 802 is away from the cold shear 1. The frame body 1001 of the tail material pushing member is installed on the first cross bar 801, that is, the tail material pushing member is located in front of the moving frame 8.

[0064] Considering that if the length of the remaining round bar tail material is relatively long, it may occur that the tail material pushing member installed on the right side of the moving frame 8 cannot push it. Therefore, a tail material pushing member is also installed on the left side of the moving frame 8.

[0065] As Figure 4 shown, in order to facilitate distinction, the two tail material pushing members are respectively named the first tail material pushing member 10 and the second tail material pushing member 11. Among them, the first tail material pushing member 10 is installed on the right side of the moving frame 8, and the second tail material pushing member 11 is installed on the left side of the moving frame 8.

[0066] In this way, when the steel tail material pushing device 2 is in the Figure 3 state shown in the figure, if the left end of the round bar tail material at this time exceeds the first tail material pushing member 10, that is, the left end of the round bar tail material is located on the left side of the first tail material pushing member 10, the first tail material pushing member 10 cannot play a role at this time. At this time, the second tail material pushing member 11 can be used to push the round bar tail material. Of course, a deflecting member cooperating with the second tail material pushing member 11 is also installed on the tabletop of the conveying table 101.

[0067] As an alternative embodiment, the deflecting member is no longer installed on the conveying table 101, and the compression spring 1004 is no longer installed on the rotating shaft 1003. Instead of the deflecting member, a driving device is installed on the tail stock pushing member. Specifically, the driving device includes a driving motor, which is installed on the frame 1001, and the output end of the driving motor is connected to one end of the rotating shaft 1003. In this way, the rotating shaft 1003 is driven by the driving motor to rotate to adjust the inclination angle of the rotating frame 1002.
