Description

Technical Field

[0001] This utility model relates to the field of metallurgical machinery and equipment technology, and in particular to a device that can absorb shearing force and a flying shear machine used in transverse shearing motion. Background Technology

[0002] In metallurgical steel rolling production lines, flying shears are essential key equipment. They are mainly located between the upstream mill 300 and the downstream mill 400, used for shearing the head and tail of rolled pieces and for accidental breakage. The structure of existing flying shears is as follows: Figure 1 As shown, the shearing action of the flying shear on the rolled workpiece is a process in which the workpiece is subjected to shearing force and tension. At the same time, the flying shear itself is also subjected to the shearing torque exerted on it by the rolled workpiece, causing the flying shear as a whole to have a tendency to tip over.

[0003] In existing technology, the flying shear is fixed to the base (or floor) by bolts connecting it to the base plate (or base). The base (or floor) is then fixed to the foundation by anchor bolts. This allows the shearing torque to be transmitted through the flying shear itself to the anchor bolts on the base plate, thus bearing the shearing torque generated by the flying shear shearing the rolled workpiece. When the flying shear shears the rolled workpiece, the shearing torque is transmitted through the flying shear itself to the anchor bolts. Therefore, the existing method of transmitting shearing torque in flying shear equipment inevitably has the following drawbacks: First, all the shearing torque generated by the system is transmitted to the anchor bolts on the equipment foundation, which can easily cause the anchor bolts to fail under impact loads; second, the bolts connecting the flying shear to the base or base plate are also prone to failure under impact loads.

[0004] In view of this, based on years of experience in production and design in this and related fields, the inventor has designed a device that can absorb shearing force and a flying shear machine for transverse shearing motion through repeated experiments, in order to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a device that can absorb shear force and a flying shear machine for transverse shearing motion. The device can absorb part of the shear force inside, reduce the impact of shear force on the flying shear equipment, and reduce the stress on the anchor bolts of the flying shear equipment, thus extending its service life.

[0006] To achieve the above objectives, this utility model proposes a device capable of absorbing shear force. The device includes at least a crossbeam, a flying shear base plate, and two supporting columns. The supporting columns are fixed to the flying shear base plate. The upper part of each supporting column is fixedly connected to the crossbeam. The two supporting columns, the crossbeam, and the flying shear base plate form a closed overall frame structure, and the flying shear equipment is enclosed within this overall frame structure. The crossbeam presses down on the flying shear equipment and prevents the flying shear equipment from tipping over during shearing.

[0007] The device for absorbing shear force as described above, wherein the flying shear base plate is fixed to the equipment foundation.

[0008] In the device for absorbing shear force as described above, a left support plate is provided between the support column on the left side and the flying shear device.

[0009] As described above, in the device for absorbing shear force, the left support plate is fixedly connected by support plate fasteners to the left side plate and top of the flying shear device, as well as to the support column located on the left side.

[0010] In the device for absorbing shear force as described above, a right support plate is provided between the support column on the right side and the flying shear device.

[0011] As described above, in the device for absorbing shear force, the right support plate is fixedly connected by support plate fasteners to the right side plate and top of the flying shear device, as well as to the support column located on the right side.

[0012] As described above, in the device for absorbing shear force, the flying shear base plate is provided with a lower left support plate, which is fixedly connected to the left side plate of the flying shear device and the flying shear base plate.

[0013] As described above, in the device for absorbing shear force, the flying shear base plate is provided with a lower right support plate, which is fixedly connected to the right side plate of the flying shear device and the flying shear base plate.

[0014] In the device described above that can absorb shear force, a positioning key is provided between the bottom of the support column and the base plate of the flying shear.

[0015] This utility model also proposes a flying shear machine for transverse shearing motion, including a flying shear device fixed to a flying shear base plate, wherein the flying shear base plate, a support column fixed on its surface, and a crossbeam connected above the support column form a closed overall frame structure, and the flying shear device is enclosed within the overall frame structure, forming the overall structure of the flying shear machine.

[0016] As described above, in the flying shear machine used for transverse shearing motion, a support plate is provided within the overall frame structure. The support plate is located between the flying shear device and the support column, and the support plate is connected to the flying shear device and the support column by support plate fasteners.

[0017] As described above, in the flying shear machine used for transverse shearing motion, the overall frame structure includes a lower support plate located between the flying shear device and the flying shear base; the lower support plate is connected to the flying shear device and the flying shear base plate by support plate fasteners.

[0018] Compared with the prior art, the present invention has the following features and advantages:

[0019] This invention proposes a shear-absorbing device and its flying shear machine. The flying shear is fixed to a base plate, while a crossbeam presses it down from above. In operation, when the flying shear is subjected to shearing torque, the crossbeam first presses it down from above to reduce the tendency to tip over during shearing. Furthermore, because the frame structure formed by the base plate, support column, and crossbeam is integrated, the shearing torque is transferred to this frame structure. Clearly, the overall bending section modulus of the frame structure formed by the base plate, support column, and crossbeam is much greater than that of the base plate alone. Based on this frame structure, most of the shearing torque is absorbed before it is transferred to the anchor bolts of the equipment foundation. Therefore, the torque borne by both the connecting bolts between the flying shear and the base plate, and the anchor bolts between the base plate and the foundation, is greatly reduced, effectively extending the lifespan of the fixed connecting bolts. Meanwhile, since the flying shear equipment is enclosed within a frame structure, the vibration of the flying shear equipment during operation is greatly reduced, thereby achieving the technical effect of extending the service life of the flying shear equipment.

[0034] The details of this utility model can be more clearly understood by referring to the accompanying drawings and the description of specific embodiments. However, the specific embodiments of this utility model described herein are for illustrative purposes only and should not be construed as limiting the utility model in any way. Under the teachings of this utility model, those skilled in the art can conceive of any possible modifications based on this utility model, and these should all be considered to fall within the scope of this utility model.

[0035] like Figures 2 to 7As shown, this utility model proposes a device 100 that can absorb shear force. The device 100 includes at least a crossbeam 3, a flying shear base plate 1, and two support columns 2. The support columns 2 are fixed on the flying shear base plate 1. The upper part of the support columns 2 is fixedly connected to the crossbeam 3. The two support columns 2, the crossbeam 3, and the flying shear base plate 1 form a closed overall frame structure, and the flying shear device 200 is enclosed within this overall frame structure. The crossbeam 3 presses down on the flying shear device 200 to prevent the flying shear device 200 from tipping over under shear conditions.

[0036] The device 100 for absorbing shear force proposed in this utility model has a flying shear device 200 fixed to a flying shear base plate 1 below, while a crossbeam 3 presses down on the flying shear device 200 from above. In operation, when the flying shear device 200 is subjected to a shearing moment B, the crossbeam 3 first presses down on the flying shear device 200 from above to reduce the tendency of the flying shear device 200 to tip over during shearing. Furthermore, since the frame structure formed by the flying shear base plate 1, supporting column 2, and crossbeam 3 of the flying shear device 200 is combined into an integral structure, the shearing moment B experienced by the flying shear device 200 is transmitted to this frame structure. Clearly, the overall bending section modulus of the frame structure formed by the flying shear base plate 1, supporting column 2, and crossbeam 3 of the flying shear device 200 is much greater than the bending section modulus of the flying shear base plate 1 alone, and based on this frame structure, most of the shearing moment B is absorbed during its transmission to the anchor bolts 12 of the equipment foundation 9. Therefore, the torque borne by both the connecting bolts 13 between the flying shear device 200 and the flying shear base plate 1, and the anchor bolts 12 between the flying shear base plate 1 and the equipment foundation 9, is greatly reduced, effectively extending the service life of the fixed connecting bolts 13 of the flying shear device 200. Simultaneously, since the flying shear device 200 is enclosed within a frame structure, the vibration of the flying shear device 200 during operation is greatly reduced, thereby achieving the technical effect of extending the service life of the flying shear device 200.

[0037] In one optional embodiment of this utility model, the flying shear base plate 1 is fixed to the equipment foundation 9.

[0038] In an optional example of this implementation, the flying shear base plate 1 is fixed to the equipment foundation 9 by a plurality of anchor bolts 12.

[0039] In one optional embodiment of this utility model, the crossbeam 3 is a horizontal crossbeam, and the supporting column 2 is fixedly connected to the crossbeam 3 by the crossbeam fastener 7.

[0040] In one optional embodiment of this utility model, such as Figure 2 , Figure 3 As shown, the two support columns 2 are located on the left and right sides of the flying shear device 200, respectively, that is, the two support columns 2 are located on the inlet side and outlet side of the flying shear device 200.

[0041] In an optional example of this embodiment, the support column 2 is provided with a window 21, through which the rolling stock conveying device and the rolling stock on it cooperate with the flying shear device 200 pass, so that the rolling stock can pass smoothly through the flying shear device 200.

[0042] In one optional embodiment of this utility model, such as Figure 4 , Figure 4-1 , Figure 4-2 As shown, a left support plate 4 is symmetrically provided between the left-side support column 2 and the flying shear device 200. The left support plate 4 can eliminate the gap between the left-side support column 2 and the flying shear device 200, so that the torque generated by the flying shear device 200 can be transmitted to the frame structure not only through the crossbeam 3, but also through the left support plate 4, thereby increasing the strength of the frame structure and making the frame structure more stable.

[0043] In one optional example of this implementation, such as Figure 4-1 , Figure 4-2 As shown, two left support plates 4 are symmetrically arranged on opposite sides of the rolling line (window 21, rolling conveyor).

[0044] In an optional example of this embodiment, the left support plate 4 is fixedly connected by support plate fasteners 8 to the left side plate and top of the flying shear device 200, as well as to the support column 2 located on the left side.

[0045] In one optional embodiment of this utility model, such as Figure 5 , Figure 5-1 , Figure 5-2 As shown, a right support plate 5 is symmetrically provided between the right-side support column 2 and the flying shear device 200. The right support plate 5 eliminates the gap between the right-side support column 2 and the flying shear device 200, so that the torque generated by the flying shear device 200 can be transmitted to the frame structure not only through the crossbeam 3, but also through the right support plate 5, thereby increasing the stiffness of the frame structure and making the frame structure more stable.

[0046] In one optional example of this implementation, two right support plates 5 are symmetrically arranged on opposite sides of the rolling line (window 21, rolling mill conveying equipment).

[0047] In an optional example of this implementation, the right support plate 5 is fixedly connected to the right side plate and top of the flying shear device 200, as well as the support column 2 located on the right side, by support plate fasteners 8, thereby increasing the rigidity of the frame structure and making the frame structure more stable.

[0048] In one optional embodiment of this utility model, the left support plate 4 and the right support plate 5 are respectively L-shaped, which can better stabilize the flying shear machine.

[0049] In one optional embodiment of this utility model, the distance between the flying shear device 200 and the support column 2 on its left side is less than the distance between it and the support column 2 on its right side.

[0050] Furthermore, the width of the left support plate 4 is 590mm, and the width of the right support plate 5 is 1350mm.

[0051] In one optional embodiment of this utility model, the support plate fastener 8 is a bolt assembly.

[0052] In an optional embodiment of this invention, a lower left support plate 10 is provided on the flying shear base plate 1, and the lower left support plate 10 is fixedly connected to the left side plate of the flying shear device 200 and the flying shear base plate 1, respectively. With the above structure, the torque generated by the flying shear device 200 can also be transmitted to the frame structure through the lower left support plate 10, further increasing the rigidity of the frame structure and making it more stable.

[0053] In an optional embodiment of this utility model, a lower right support plate 11 is provided on the flying shear base plate 1, and the lower right support plate 11 is fixedly connected to the right side plate of the flying shear device 200 and the flying shear base plate 1 respectively. With the above structure, the torque generated by the flying shear device 200 can also be transmitted to the frame structure through the lower right support plate 11, further increasing the rigidity of the frame structure and making the frame structure more stable.

[0054] The device 100 for absorbing shear force proposed in this utility model connects the frame structure consisting of the support column 2, the crossbeam 3, and the flying shear base plate 1 to the flying shear equipment 200 into an integrated structure via the left support plate 4, the right support plate 5, the lower left support plate 10, and the lower right support plate 11. This effectively disperses and absorbs the torque generated by the flying shear equipment 200 during operation, increasing the overall structural stability of the flying shear machine of this utility model.

[0055] In an optional embodiment of this utility model, a positioning key 6 is provided between the support column 2 and the flying shear base plate 1. The positioning key 6 enables precise positioning between the support column 2 and the flying shear base plate 1, so that a portion of the torque absorbed by the shear force absorbing device 100 can be borne by the positioning key 6, greatly extending the service life of the shear force absorbing device 100.

[0056] This utility model also proposes a flying shear machine for transverse shearing motion, including a flying shear device 200 fixed on a flying shear base plate 1. The flying shear base plate 1 and the support column 2 fixed on its surface, as well as the crossbeam 3 connected above the support column 2, form a closed overall frame structure. The flying shear device 200 is enclosed within this overall frame structure, forming the overall structure of the flying shear machine.

[0057] The flying shear machine for transverse shearing motion proposed in this utility model consists of a frame structure formed by the flying shear base plate 1, supporting column 2, and crossbeam 3 of the flying shear device 200, which is combined into an integral structure. The overall bending section modulus of this frame structure is much greater than that of the flying shear base plate 1 alone. Furthermore, based on this frame structure, most of the torque A borne by the frame structure is absorbed during the transmission to the anchor bolts 12 of the equipment foundation 9. Therefore, the torque borne by both the connecting bolts 13 between the flying shear device 200 and the flying shear base plate 1, and the anchor bolts 12 between the flying shear base plate 1 and the equipment foundation 9, is significantly reduced, effectively extending the service life of the fixed connecting bolts 13 of the flying shear device 200.

[0058] The flying shear machine for transverse shearing motion proposed in this utility model has its flying shear device 200 enclosed in a frame structure, which greatly reduces the vibration of the flying shear device 200 during operation, thereby achieving the technical effect of extending the service life of the flying shear device 200.

[0059] In an optional embodiment of this utility model, a support plate is provided within the overall frame structure. The support plate is located between the flying shear device 200 and the support column 2, and the support plate is connected to the flying shear device 200 and the support column 2 by support plate fasteners 8.

[0060] In an optional example, the support plate includes a left support plate 4 and a right support plate 5, with the left support plate 4 connected between the flying shear device 200 and the support column 2 on its left side, and the right support plate 5 connected between the flying shear device 200 and the support column 2 on its right side.

[0061] In an optional embodiment of this utility model, a lower support plate is provided inside the overall frame structure, and the lower support plate is located between the flying shear device 200 and the flying shear base plate 1; the lower support plate is connected to the flying shear device 200 and the flying shear base plate 1 by support plate fasteners 8.

[0062] In one alternative example, the lower support plate includes a lower left support plate 10 and a lower right support plate 11, with the lower left support plate 10 located on the left side of the flying shear device 200 and the lower right support plate 11 located on the right side of the flying shear device 200.

[0063] The device 100 and flying shear machine proposed in this utility model can absorb part of the shear force inside the device 100, reduce the impact of the shear force on the flying shear machine 200, and reduce the stress on the anchor bolts 12 of the flying shear machine 200, thus extending its service life.

[0064] The device 100 and flying shear machine proposed in this utility model can absorb shear force, which reduces the vibration value of the flying shear equipment 200 and extends its service life.

[0065] The detailed explanations of the above embodiments are intended only to explain the present invention so as to facilitate a better understanding of the present invention. However, these descriptions should not be construed as limiting the present invention for any reason. In particular, the various features described in different embodiments can be arbitrarily combined with each other to form other embodiments. Unless there is an explicit description to the contrary, these features should be understood to be applicable to any embodiment, and not limited to the described embodiments.
