Description

Technical Field

[0001] This application belongs to the field of profile steel processing technology, specifically relating to a steel cutting device for fixed-length steel on a heavy steel production line. Background Technology

[0002] In the daily operation of a heavy steel production line, when it comes to fixed-length operations during steel transportation or bundling of finished steel products, it is necessary to use lifting baffles to stop the steel being transported.

[0003] Currently, the traditional method for stopping steel transport mainly involves using hydraulic cylinders to vertically lift a baffle. When the steel moves forward with the conveyor to a designated position, the hydraulic cylinder activates, quickly lifting the baffle vertically to stop the steel from advancing further. However, the steel being transported exerts significant horizontal impact force, and the baffle is prone to damage and deformation after frequent impacts. Once the baffle is damaged, the production line needs to be shut down for repair and replacement, severely impacting production progress. Furthermore, existing stopping devices, as independent pieces of equipment, occupy a large area, making them extremely inefficient in terms of space utilization. Their operation is cumbersome, and subsequent maintenance is also complex and costly, affecting overall work efficiency. Utility Model Content

[0004] This application provides a steel cutting device specifically for fixed-length steel on a heavy steel production line, aiming to solve the technical problems in the prior art, such as the baffle being easily deformed by impact, requiring frequent maintenance and repair, and the combination of hydraulic cylinder and baffle being difficult to maintain, which affects the efficiency of steel bundling operations.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A steel cutting-off device specifically designed for cut-to-length steel on a heavy steel production line is provided, comprising:

[0007] Base;

[0008] A flip plate is rotatably connected to the base. The rotation axis of the flip plate is perpendicular to the vertical direction and also perpendicular to the transport path of the steel. The surface of the flip plate is parallel to its own rotation axis.

[0009] A baffle is attached to the flipping plate. The baffle has a stop state in which the plate surface is perpendicular to the transport path of the steel. In the stop state, the baffle can contact the end of the steel.

[0010] A telescopic assembly, connected to the base, the telescopic assembly having a drive end hinged to the flip plate, the drive end being used to drive the flip plate to rotate about the rotation axis of the flip plate; and

[0011] A buffer assembly is disposed between the flip plate and the baffle, and the buffer assembly is configured with a preload force to push the baffle away from the flip plate.

[0012] In one possible implementation, the side of the baffle away from the flip plate forms a stopping surface that can contact the end of the steel in the stopped state, and the stopping surface is covered with a zinc coating.

[0013] In one possible implementation, the base is provided with a support frame, and the flip plate is provided with a connecting plate at one end near the support frame. The surface of the connecting plate is perpendicular to the transport path of the steel, and the connecting plate is rotatably connected to the top of the support frame, with the axis of rotation perpendicular to the vertical direction.

[0014] In one possible implementation, the support frame includes:

[0015] Two support plates, parallel to each other and respectively disposed on the base, are spaced apart along a direction perpendicular to the steel transport path;

[0016] Two pins are respectively located on the top of the corresponding support plates, with their axes overlapping. A rotating hole is provided on the connecting plate, and the pins pass through and rotatably engage with the rotating hole.

[0017] A connecting cylinder is placed between the two support plates, and the two pins are respectively inserted into the corresponding ends of the connecting cylinder.

[0018] In one possible implementation, the support frame further includes a limiting plate mounted on the connecting cylinder. The limiting plate has a limiting groove at its top, which can engage with the bottom of the flip plate in the horizontal direction to limit the flipping path of the flip plate.

[0019] In one possible implementation, the pin has a connecting hole radially formed at one end near the connecting cylinder, and the connecting cylinder has a mounting hole corresponding to the connecting hole. The support frame also includes a pin that passes through both the connecting hole and the mounting hole to fix the connecting cylinder and the pin together.

[0020] In one possible implementation, a connector is provided between the baffle and the flip plate. The connector includes a fastening bolt and a nut. The fastening bolt passes through the baffle and the flip plate and is screwed to the nut. The nut and the nut of the fastening bolt cooperate to clamp and fix the baffle and the flip plate.

[0021] In one possible implementation, the buffer assembly includes a plurality of elastic elements, which are sleeved on the outer periphery of the bolt and abut against the baffle and the flip plate at their two ends, respectively. The elastic elements are configured with a preload force to push the baffle and the flip plate away from each other.

[0022] In one possible implementation, the buffer assembly includes multiple buffers arranged in a rectangular array or a circular array.

[0023] In one possible implementation, the scaling component includes:

[0024] The mounting base is connected and fixed to the upper surface of the base, and is spaced apart from the flip plate in a direction parallel to the steel transport path; and

[0025] The telescopic drive component is hinged at one end to the base and at the other end to the flip plate. When the baffle is in the stopped state, the telescopic drive component, the base, and the flip plate cooperate to form a triangular structure.

[0026] The steel cutting-off device for fixed-length steel on a heavy-duty steel production line provided in this application, compared with existing technologies, uses a tilting plate connected to a baffle. During fixed-length operation, the drive end of the drive assembly pushes the tilting plate to rotate. The tilting plate drives the baffle to swing around its own pin shaft with the base until the baffle surface is parallel to the vertical direction, thus stopping the steel being conveyed. When the steel comes into contact with the baffle, the tilting plate and drive assembly generate a force on the other side of the baffle to prevent the steel from continuing to be conveyed, stopping the steel. Several buffer components are set between the tilting plate and the steel plate. The buffer components disperse and absorb the horizontal impact force of the steel, preventing the baffle from directly bearing the entire impact force, thereby reducing the damage and deformation of the baffle due to frequent impacts, extending the service life of the baffle, reducing the risk of damage to the baffle and drive assembly, reducing the number of equipment downtime maintenance, reducing the labor intensity of employees, and improving work efficiency. The connection relationship between the various components is relatively clear, which facilitates the inspection, repair, and replacement of each component by the staff during later maintenance. The reasonable connection and layout between the base, flip plate, baffle, telescopic components and buffer components form a relatively compact overall structure. When not in use, the baffle can be flipped down with the flip plate to reduce space occupation. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0043] Please refer to the following: Figures 1 to 4 This application describes a steel cutting-off device specifically for cut-to-length steel on a heavy-duty steel production line. The device comprises a base 1, a tilting plate 2, a baffle 3, a telescopic assembly 4, and several buffer assemblies 5. The tilting plate 2 is rotatably connected to the base 1. The axis of rotation of the tilting plate 2 is perpendicular to the vertical direction and also perpendicular to the transport path of the steel. The surface of the tilting plate 2 is parallel to its own axis of rotation. The baffle 3 is fitted to the tilting plate 2 and has a cutting-off state where its surface is perpendicular to the transport path of the steel. In this cutting-off state, the baffle 3 can contact the end of the steel. The telescopic assembly 4 is connected to the base 1 and has a drive end hinged to the tilting plate 2. The drive end is used to push the tilting plate 2 to rotate around its axis of rotation. The buffer assemblies 5 are located between the tilting plate 2 and the baffle 3 and are configured with a pre-tightening force to push the baffle 3 away from the tilting plate 2.

[0044] It should be noted that, for reference Figure 1 The baffle 3 has a stop state where its surface is parallel to the vertical direction and in contact with the steel; see reference Figure 2 It also has a baffle 3 that flips downward with the flip plate 2, so that the surface of the baffle 3 is perpendicular to the vertical direction in an idle state, and the drive end can push the flip plate 2 to switch between the idle state and the stop state.

[0045] It should be noted that, Figure 1 and Figure 2 The horizontal dashed line in the image refers to the transportation path of the steel.

[0046] The principle adopted in this embodiment is as follows: the flip plate 2 is connected to the baffle 3. When the fixed length operation is performed, the drive end of the drive component pushes the flip plate 2 to rotate. The flip plate 2 drives the baffle 3 to swing around the pin 112 between itself and the base 1 until the plate surface of the baffle 3 is parallel to the vertical direction. The baffle 3 stops the steel being conveyed. When the steel comes into contact with the baffle 3, the flip plate 2 and the drive component generate a force on the other side of the baffle 3 to prevent the steel from continuing to be conveyed, so that the steel stops. When the baffle 3 and the steel collide, the buffer component 5 disperses and absorbs the horizontal impact force of the steel.

[0047] The steel cutting device for fixed-length steel on a heavy-duty steel production line provided in this embodiment, compared with the prior art, uses a buffer component 5 to disperse and absorb the horizontal impact force of the steel, preventing the baffle 3 from directly bearing the entire impact force. This reduces the probability of damage and deformation of the baffle 3 due to frequent impacts, extends the service life of the baffle 3, reduces the risk of damage to the baffle 3 and drive components, reduces the number of equipment downtime maintenance, lowers the labor intensity of employees, and improves work efficiency. The connection relationship between the components is relatively clear, making it easy for staff to inspect, repair, and replace each component during later maintenance. The reasonable connection and layout between the base 1, the flipping plate 2, the baffle 3, the telescopic component 4, and the buffer component 5 form a relatively compact overall structure. When not in use, the baffle 3 can be flipped downwards with the flipping plate 2, reducing space occupation.

[0048] In some embodiments, see Figure 1 The side of the baffle 3 facing away from the tilting plate 2 forms a stopping surface 31 that can contact the end of the steel when stopped. The stopping surface 31 is covered with a zinc coating. The stopping function and the structural connection function are clearly distinguished. The stopping surface 31 can better play its role in blocking the steel, while the connection with the tilting plate 2 on the other side ensures the stable installation of the baffle 3 in the device. The zinc coating has strong corrosion resistance, which can play a role in preventing corrosion and rust, extending the service life of the baffle 3 and reducing the number of times the baffle 3 needs to be replaced.

[0049] In some embodiments, see Figures 1 to 3 The base 1 is equipped with a support frame 11. A connecting plate 21 is located at one end of the tilting plate 2 near the support frame 11. The surface of the connecting plate 21 is perpendicular to the steel transport path. The connecting plate 21 is rotatably connected to the top of the support frame 11, and the axis of rotation is perpendicular to the vertical direction. When the telescopic component 4 pushes the tilting plate 2 to rotate, it ensures that the tilting plate 2 swings smoothly around the connection point at the top of the support frame 11, allowing the baffle 3 to accurately reach the stopping position, thus improving the stability and reliability of the device. The perpendicularity of the connecting plate 21 to the steel transport path allows the rotation of the tilting plate 2 and the baffle 3 to match the steel transport path, making the device structure more compact and reducing space occupation.

[0050] In some embodiments, see Figures 1 to 4 The support frame 11 includes two support plates 111, two pins 112, and a connecting cylinder 113. The two support plates 111 are parallel to each other and respectively mounted on the base 1, spaced apart along a direction perpendicular to the steel transport path. The two pins 112 are respectively located on the top of their respective support plates 111, with their axes overlapping. A rotating hole is provided on the connecting plate 21, through which the pins 112 pass and rotate. The connecting cylinder 113 is placed between the two support plates 111, with the two pins 112 inserted into their corresponding ends. The two support plates 111 provide a stable support foundation for the entire support frame 11, and their spaced arrangement accommodates different sizes of flip plates 2. The rotational fit between the pin 112 and the rotating hole ensures the flexibility of the rotation of the flip plate 2. The connecting cylinder 113 connects the two pins 112, which can enhance the overall structural strength and stability of the support frame 11, ensure that the flip plate 2 will not shake or deviate during rotation, and improve the working accuracy of the stopping device.

[0051] In practice, the two support plates 111 are spaced apart along a direction perpendicular to the steel conveying direction, and the surface of the support plates 111 is perpendicular to the steel conveying direction. The distance between the two support plates 111 is greater than the length of the baffle 3. The two pins 112 are respectively connected to the two ends of the connecting cylinder 113. The spaced arrangement of the two support plates 111 does not affect the up-and-down swing of the tilting plate 2.

[0052] In some embodiments, see Figures 1 to 4 The support frame 11 also includes a limiting plate 115, which is mounted on the connecting cylinder 113. A limiting groove is formed at the top of the limiting plate 115, which can engage horizontally with the bottom of the flipping plate 2 to restrict the flipping path of the flipping plate 2. The limiting plate 115 further enhances the control over the flipping path of the flipping plate 2, preventing it from exceeding the predetermined range during rotation. This ensures the accuracy and stability of the baffle 3's position when stopping the steel, avoids stopping failure or device damage due to excessive flipping of the flipping plate 2, and improves the safety and reliability of the stopping device.

[0053] It should be noted that the side where the baffle 3 is located is defined as the front side, and the side where the flip plate 2 is located is defined as the rear side. The drive component 4 is located on the rear side of the support frame 11, and the limit groove has an opening on the rear side to limit the flip plate 2 from flipping forward too much.

[0054] In some embodiments, see Figure 3The pin 112 has a connecting hole radially formed at one end near the connecting cylinder 113, and a corresponding mounting hole is formed on the connecting cylinder 113. The support frame 11 also includes a pin 114, which passes through both the connecting hole and the mounting hole to fix the connecting cylinder 113 and the pin 112. Fixing the connecting cylinder 113 and the pin 112 together with the pin 114 makes the structure of the support frame 11 more robust. Furthermore, the connection method facilitates installation and disassembly, allowing for easy disassembly and assembly of the support frame during device maintenance or repair, reducing maintenance costs and difficulty, and improving the maintainability of the device.

[0055] It should be noted that the two ends of the pin 114 protrude from the mounting hole. When the pin 114 passes through both the connection hole and the mounting hole, the two ends of the pin 114 are respectively connected to the nuts 62 so that the pin 114 is always inserted into the connection hole and the mounting hole. This technique is a conventional operation that can be performed by those skilled in the art.

[0056] In some embodiments, see Figure 1 and Figure 2 A connecting component 6 is provided between the baffle 3 and the tilting plate 2. The connecting component 6 includes a fastening bolt 61 and a nut 62. The fastening bolt 61 passes through the baffle 3 and the tilting plate 2 and is screwed onto the nut 62. The nut 62 and the nut of the fastening bolt 61 cooperate to clamp and fix the baffle 3 and the tilting plate 2. The clamping and fixing method of the bolt and nut 62 makes the connection between the baffle 3 and the tilting plate 2 firm and easy to disassemble, which can ensure the connection stability between the baffle 3 and the tilting plate 2, so that they can work together to withstand the impact force when steel is impacted. When the baffle 3 is damaged by impact, it can be quickly replaced without disassembling the entire device, shortening the maintenance time and reducing maintenance costs.

[0057] In some embodiments, see Figure 1 and Figure 2 The buffer assembly 5 includes several elastic elements 51, which are sleeved around the outer periphery of the bolt and abut against the baffle 3 and the tilting plate 2 at both ends, respectively. The elastic elements 51 are configured with a preload to push the baffle 3 and the tilting plate 2 away from each other. When steel impacts the baffle 3, the preload and compressive deformation of the elastic elements 51 absorb the impact energy, forming a flexible buffer. This converts the impact force of the steel into the elastic potential energy of the elastic elements 51, further reducing the impact force on the baffle 3 and lowering the possibility of damage or deformation. Simultaneously, the preload of the elastic elements 51 ensures that the baffle 3 maintains a certain relative position with the tilting plate 2 under normal conditions, ensuring the normal operation of the device and improving its service life and reliability.

[0058] Optionally, the elastic element 51 can be a disc spring, which has good continuity and can meet the usage requirements. Alternatively, a helical spring can be used, as long as it can alleviate the impact force on the dispersion baffle 3.

[0059] In some embodiments, the buffer assembly includes multiple buffer elements arranged in a rectangular array or a ring array. This rectangular or ring array arrangement allows the impact force of the steel to be more evenly distributed across the buffer elements, preventing deformation caused by localized stress concentration, improving the overall buffering efficiency of the buffer assembly 5, and extending the service life of the baffle 3.

[0060] In some embodiments, see Figure 1 and Figure 2 The telescopic assembly 4 includes a mounting base 41 and a telescopic drive component 42. The mounting base 41 is fixed to the upper surface of the base 1 and is spaced apart from the tilting plate 2 in a direction parallel to the steel transport path. One end of the telescopic drive component 42 is hinged to the base 1, and the other end is hinged to the tilting plate 2. When the baffle 3 is in the stopped state, the telescopic drive component 42, the base 1, and the tilting plate 2 cooperate to form a triangular structure. The triangular structure has the characteristic of strong stability, which enables the device to more stably withstand the impact force of the steel when stopping it, reducing the shaking and deformation of the device. At the same time, the hinged method of the telescopic drive component 42 makes the rotation of the tilting plate 2 more flexible, making it easier to control the raising and lowering of the baffle 3.

[0061] In practice, the telescopic drive component 42 can be a hydraulic cylinder or a telescopic cylinder. It can simply change its own length to push the tilting plate 2 to swing.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
