Description

Technical Field

[0001] The invention relates to the technical field of steel billet shearing and conveying, and in particular to an automatic feeding mechanism for a shearing line. Background Art

[0002] The billet shearing operation is an important link in the steel production process. It involves cutting the long strip or cylindrical billets produced by continuous casting into suitable short sections according to a predetermined length so as to further process them into finished steel products. The high-temperature billets are relatively soft and easier to cut. Therefore, the billet shearing operation is usually carried out under high temperature conditions. In the related technology, the billets are transported by conveying equipment. The conveying equipment is prone to deformation during the long-term contact with the high-temperature billets, which affects the normal transportation of the billets and even interrupts the conveying action of the billets during the transportation process, causing the billets to stagnate on the conveying equipment.

[0003] The patent document with authorization announcement number CN114919984B discloses a conveying system for steel billet production, including multiple conveying lines arranged in parallel and adjacent to each other, and also including guide rails, pulling devices, longitudinal driving mechanisms and clamping mechanisms. The guide rails span the conveying lines and are located on one side of the tail end of the conveying lines. A track is provided on the guide rails. The pulling device includes a winding mechanism and a pulling wire. The bottom end of the winding mechanism can be slidably clamped in the track. The head end of the pulling wire is wound on the winding mechanism, and the winding mechanism can reel in or unwind. The longitudinal driving mechanism is arranged on the guide rails and connected to the winding mechanism, and is used to drive the winding mechanism forward or backward along the track. The clamping mechanism can be detachably connected to the tail end of the pulling wire, and the clamping mechanism can clamp the steel billet. The conveying system provided by the patent document can pull the steel billet out of the conveying track after the conveying is interrupted, thereby improving work efficiency and safety.

[0004] The deformation caused by the long-term contact between the conveying equipment and the high-temperature steel billet can easily cause the steel billet to deviate from the preset conveying path during the conveying process, especially in the conveying operation of cylindrical steel billets. Since the contact position between the cylindrical steel billet and the conveying equipment is smaller, the conveying stability of the round steel billet is poor and it is more likely to deviate during the conveying process. When the steel billet is sheared by the shearing production line, in order to ensure the shearing accuracy of the steel billet, it is necessary to ensure that the center line of the steel billet and the center line of the shearing machine are aligned. The conveying system provided by the above patent document can pull out the steel billet through the clamping mechanism and the winding mechanism after the steel billet conveying is interrupted, but it is inconvenient to correct the deviation of the steel billet in actual operation. Summary of the invention

[0011] Preferably, a support plate is further provided on the conveying component, the shape of the support plate is adapted to the shape of the steel billet, and a plurality of troughs corresponding one-to-one to each of the rollers are provided on the support plate.

[0012] The beneficial effects are: improving the supporting strength of a pair of circular steel billets of the conveying assembly during the shearing operation, the shape of the support plate can better adapt to the shape of the steel billet, and by adding a support plate, the supporting effect of the circular steel billet during the shearing operation can be improved, and the shearing effect of the circular steel billet can be improved.

[0016] The beneficial effects are: improving the working flexibility of the support assembly, when the billet pressing roller enters the interior of the connecting piece, the push block pushes the two limit members of the same group of support assemblies relatively close together until the two limit members are inserted into the limit grooves, and the side walls of the limit members are in full contact with the limit grooves. After the limit members and the limit grooves are fully fitted, the friction force between the limit members and the limit grooves improves the strength of the cooperation between the limit members and the support members.

[0022] (1) Improve the conveying accuracy of steel billets of different sizes and models. By adjusting the relative distance between the two movable parts, the tension of the conveying assembly between the two movable parts can be adjusted to adapt to steel billets of different sizes, so that the rollers of the conveying assembly can contact the bottom surface and side / side edges of the square steel billet at the same time. While conveying the steel billet, the rollers abutting the side edges or sides of the steel billet can also guide the conveying direction of the steel billet. When conveying round steel billets, the contact points between the conveying assembly and the steel billet are increased, which improves the conveying stability of the steel billet and reduces the deviation of the steel billet during the conveying process, thereby ensuring the conveying accuracy of the steel billet, further ensuring the accuracy of the subsequent shearing operation of the steel billet, and improving the shearing quality of the steel billet.

[0023] (2) Enhance the supporting effect on the shearing end of the billet during the shearing operation.

[0035] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] like Figure 1 As shown, the automatic feeding device of the shearing line of the present invention includes a frame 2, on which an adjusting component and multiple groups of conveying components are provided, the adjusting component includes two movable parts 21 and multiple adjusting parts 22, the movable part 21 can be a plate-like structure, the movable part 21 and the frame 2 are slidably matched, any movable part 21 is connected to the frame 2 through at least two adjusting parts 22, wherein the adjusting part 22 can be a cylinder, the adjusting part 22 is fixed relative to the frame 2, the protruding end of the adjusting part 22 is fixed to the movable part 21, the adjusting parts 22 connected to the same movable part 21 work synchronously, and each adjusting part 22 pushes the two connecting parts 23 to be relatively close or away when working, and each conveying component is arranged at intervals between the two movable parts 21 along the feeding direction of the frame 2, the steel billet 5 is placed on each conveying component, and the conveying component conveys the steel billet 5 to the unloading end of the frame 2, and the unloading end of the frame 2 is provided with a shearing device 1, and the shearing device 1 shears the steel billet 5 at the unloading end of the frame 2.

[0037] like Figure 5As shown, the conveying assembly includes a plurality of connecting members 23 and a plurality of rollers 24, wherein the number of connecting members 23 and rollers 24 is the same and corresponds to each other, the connecting member 23 is frame-shaped, the rollers 24 are arranged in the connecting member 23 and rotatably cooperate with the connecting member 23, two adjacent connecting members 23 are hinged, and the two connecting members 23 at both ends of the conveying assembly are respectively hinged to the two movable members 21, and each roller 24 is in rolling contact with the steel billet 5. In order to ensure that each conveying assembly smoothly conveys the steel billet 5 to the shearing device 1, there is a self-driven roller 24, and the self-driven roller 24 4 rotates, driving the steel billet 5 to move. Preferably, the two rollers 24 at both ends of the conveying assembly are set as self-driving rollers 24. The arrangement of the self-driving rollers 24 on different conveying assemblies can be set according to actual production requirements. The self-driving rollers 24 can be set on each group of conveying assemblies, or the self-driving rollers 24 can be arranged at intervals on each conveying assembly, so as to achieve the requirement of smoothly conveying the steel billet 5 to the shearing device 1. Among them, the self-driving rollers 24 belong to the prior art, and their specific structure and driving method will not be described in detail here.

[0038] In the actual production process, affected by the purpose and processing technology, there are certain differences in the shapes and sizes of different batches of steel billets 5. The adjustment component is used to adjust each conveying component to adapt the conveying component to the transportation requirements of steel billets 5 of different shapes and sizes. The connecting parts 23 of the conveying component are hinged. By adjusting the relative distance between the two movable parts 21, the tension of the conveying component between the two movable parts 21 can be adjusted. When conveying a larger square steel billet 5, the heavy square steel billet 5 has a relatively regular shape, is more stable during the conveying process, and is not easy to deviate. The two movable parts 21 can be adjusted to be relatively far apart by the adjustment part 22, so that the conveying component is in a relatively tensioned state. The specific state can be referred to Figure 2 The status of the conveying components;

[0039] like Figure 3 As shown, when conveying a small-sized square steel billet 5, the two movable parts 21 can be adjusted to be relatively close to each other, the tension of the conveying assembly can be reduced, the bottom surface of the steel billet 5 contacts the roller 24 in the middle position, and the rollers 24 near the two ends of the conveying assembly can simultaneously abut against the side edges of the bottom of the steel billet 5, or directly contact the side of the steel billet 5, so as to limit and guide the conveying path of the steel billet 5, improve the stability of the movement of the steel billet 5, and reduce the deviation of the small-sized steel billet 5 during the movement;

[0040] like Figure 1 and Figure 5As shown, when the two movable parts 21 are close to each other, the conveying assembly is in a state of lower tension, which is also convenient for conveying the round steel billet 5. When conveying the round steel billet 5, the overall shape of the conveying assembly adapts to the shape change of the steel billet 5. When the conveying assembly conveys the round steel billet 5, the contact points between the conveying assembly and the round steel billet 5 are increased, thereby improving the stability of conveying the steel billet 5 and reducing the axial deviation of the steel billet 5 during the conveying process. In addition, the different tension levels of the conveying assembly can also better adapt to steel billets 5 of different diameters, thereby facilitating stable and precise conveying of steel billets 5 of different diameters.

[0041] The number of connectors 23 and rollers 24 in a conveying assembly can be determined based on actual production needs. To reduce cluttered lines, a conveying assembly in the accompanying drawings includes three connectors 23 and rollers 24 . The content of the accompanying drawings does not limit the number of connectors 23 and rollers 24 .

[0042] like Figure 4 As shown, a base 12 is further provided at the unloading end of the frame 2, and the base 12 can be fixed at the shearing station of the shearing device 1. A support platform 13 is provided on the base 12, and the height of the support platform 13 increases along the moving direction of the billet 5, that is, the upper end surface of the support platform 13 is in the shape of an inclined slope, and the highest end of the support platform 13 is longitudinally opposite to the shearing blade 11 of the shearing device 1. By providing the support platform 13, the contact area between the billet 5 and the support platform 13 is reduced during the cutting operation of the billet 5, and the influence of extrusion deformation of the billet 5 during the cutting process is further reduced.

[0043] like Figures 5 to 9 As shown, during the shearing operation of the billet 5, the shearing blade 11 shears the billet 5, which will generate a large extrusion force on the billet 5. The temperature of the billet 5 itself is relatively high. During the shearing operation, the extrusion force generated by the shearing blade 11 on the billet 5 will act on the conveying assembly at the unloading end of the frame 2 through the billet 5. Because the conveying assembly is in contact with the high-temperature billet 5 only through the roller 24, the roller 24 of the conveying assembly at the unloading end of the frame 2 is more susceptible to damage than other rollers 24 under high temperature and extrusion during long-term operation. In order to improve the supporting effect on the shearing end of the billet 5 during the shearing operation, It also reduces damage to the conveying assembly at the unloading end of the frame 2 and extends the service life of the conveying assembly. A support assembly can be set on the conveying assembly at the unloading end of the frame 2. For ease of description, the conveying assembly located at the unloading end of the frame 2 is referred to as conveying assembly 1. Conveying assembly 1 includes multiple connecting members 3 and multiple rollers 31. Each roller 31 corresponds to each connecting member 3 one by one and rotates together. A group of support assemblies is provided between any two adjacent connecting members 3. The support assembly is used to increase support for the shear end of the billet 5 when the billet 5 is subjected to downward extrusion.

[0044] The supporting assembly includes a supporting member 4 and a limiting member 41. The supporting member 4 is fixed relative to the frame 2. Connecting shafts 311 are fixed at both axial ends of the roller 31. A connecting portion 312 is rotatably connected to the connecting shaft 311. The connecting portion 312 is slidably matched with the connecting member 3. Specifically, a connecting groove slidably matched with the connecting portion 312 can be provided on the connecting member 3. The sliding direction of the connecting portion 312 is perpendicular to the axial direction of the roller 31. The roller 31 can rotate relative to the connecting member 3 along its own axial direction, and can slide relative to the connecting member 3 along a direction perpendicular to its own axial direction, so that when each conveying assembly conveys the billet 5, the roller 31 rolls in contact with the billet 5. When the billet 5 moves into position for shearing, the roller 31 is squeezed and slides relative to the connecting member 3, so that the billet 5 contacts the upper end surface of the connecting member 3, thereby increasing the contact area between the conveying assembly and the billet 5 during the shearing operation.

[0045] Two adjacent connecting members 3 are connected by a rotating shaft 33, and a group of supporting components includes two limiting members 41, and the two limiting members 41 are elastically connected. The upper ends of the two limiting members 41 are arc-shaped. Specifically, the upper ends of the limiting members 41 can be semi-cylindrical, and the two limiting members 41 are elastically connected by elastic members 43. The elastic members 43 include but are not limited to springs and elastic telescopic rods. The upper ends of the two limiting members 41 are arranged around the outer peripheral side of the rotating shaft 33. When the two limiting members 41 are relatively close to and fit the outer wall of the rotating shaft 33, the elastic members 43 are squeezed and force is accumulated by the elastic members 43. Two limiting grooves 42 are provided on the supporting member 4, and the width of the limiting grooves 42 increases in the direction away from the symmetry plane thereof. The shape of the limiting member 41 matches the shape of the limiting grooves 42. A push block 313 is also fixed to the free end of the connecting shaft 311. The push block 313 The end surface of 13 facing the limit member 41 is an inclined surface inclined from top to bottom in the direction away from the limit member 41. During the shearing operation of the steel billet 5, when the steel billet 5 is pressed down by the roller 31 into the interior of the connecting member 3, the push block 313 pushes the two limit members 41 of the same group of supporting components to be relatively close to each other until the two limit members 41 are inserted into the limit groove 42, and the side wall of the limit member 41 is fully in contact with the limit groove 42. The contact surface of the limit member 41 and the limit groove 42 is a rough surface. After the limit member 41 and the limit groove 42 are fully fitted, under the action of the friction force between the limit member 41 and the limit groove 42, the strength of the cooperation between the limit member 41 and the support member 4 is improved, thereby fixing the relative positions of the rotating shaft 33, the limit member 41 and the support member 4, so as to stably support each connecting member 3 and improve the supporting strength of the connecting member 3 for the steel billet 5.

[0046] like Figure 7As shown, since the contact points between the round steel billet 5 and the connecting member 3 during the shearing operation are relatively few, in order to further improve the supporting strength of the round steel billet 5, a support plate 32 is further provided on the conveying component 1. The support plate 32 can be detachably connected to the conveying component 1. The shape of the support plate 32 is adapted to the shape of the steel billet 5. The support plate 32 is provided with a plurality of grooves corresponding to each roller 31. By providing the grooves, the support plate 32 is prevented from affecting the contact between each roller 31 and the steel billet 5, and also does not affect the movement of the roller 31 when being squeezed and retracted into the interior of the connecting member 3. The shape of the support plate 32 can better adapt to the shape of the steel billet 5. By adding the support plate 32, the supporting effect on the round steel billet 5 during the shearing operation can be improved, and the shearing effect of the round steel billet 5 can be improved.

[0047] The automatic feeding mechanism of the shearing line provided by the present invention is convenient for adjusting the cooperation mode of the conveying component according to the steel billets of different shapes and sizes, so as to realize the demand for stable conveying of steel billets of different models, improve the conveying accuracy of the steel billets, and enhance the supporting effect on the shearing end of the steel billet when shearing the steel billet, thereby reducing the extrusion damage to the conveying component of the feeder during the shearing operation and improving the flatness of the shearing surface of the steel billet.
