Description

Technical Field

[0001] This utility model relates to the technical field of corrugated web H-beam production equipment, specifically to an intelligent production line for corrugated web H-beams. Background Technology

[0002] In construction, bridge engineering, and other fields, corrugated web H-beams are widely used due to their excellent mechanical properties and economic efficiency. However, traditional H-beam production lines have many drawbacks. The various stages of the production process are not closely connected, the degree of automation is low, and a large amount of manual labor is required for operations such as handling and positioning of the flanges and processing of the web. This not only results in low production efficiency but also easily leads to unstable dimensional accuracy and inconsistent product quality due to human factors.

[0003] In the wing plate transfer process, the wing plate transfer mechanism in traditional production lines has significant drawbacks. Because the wing plate itself has a certain weight, the motor shaft of the lifting motor bears a large load during the process of driving the wing plate hanger to pick up and lift the wing plate, posing a risk of breakage. Typically, a motor with a higher power than its rated operating conditions is selected in the design, resulting in energy waste. Therefore, developing a wing plate transfer mechanism that can effectively balance the axial downward load of the lifting motor is of great significance for improving the stability and product quality of corrugated web H-beam production lines. Utility Model Content

[0004] In view of the problems and shortcomings of the existing technology, this utility model provides an intelligent production line for corrugated web H-beams.

[0005] The technical solution of this utility model is as follows:

[0006] The intelligent production line for corrugated web H-beams includes, in sequence, a wing plate cutting and blanking device, a wing plate temporary storage rack, a web plate uncoiling machine, a web plate leveling machine, an online accompanying transverse laser cutting machine, a web plate corrugating forming machine, a corrugated web and wing plate conveying device, a flipping corrugated web H-beam assembly device, a main control console, and a corrugated web H-beam blanking device.

[0007] The corrugated web and wing plate conveying equipment includes a web conveying mechanism located in the middle, wing plate conveying mechanisms on both sides of the web conveying mechanism, a wing plate loading rack on the outer side of the wing plate conveying mechanism, and a wing plate transfer mechanism connected to the upper part of the wing plate conveying mechanisms on both sides.

[0008] The wing plate transfer mechanism includes a transfer beam mounted above the wing plate conveying mechanisms on both sides. A trolley is mounted on the transfer beam, and a lifting motor is mounted on the trolley. The lifting motor is connected to and drives the wing plate lifting device to move up and down through a transmission mechanism. The bottom of the wing plate lifting device is equipped with a component to lift the wing plate.

[0009] The trolley is equipped with a balancing mechanism on one side of the wing plate lifting device to balance the axial downward load of the lifting motor.

[0010] Furthermore, the balancing mechanism includes a cylinder disposed on the outside of the wing plate lifting device. The bottom fixed end of the cylinder is connected to a trolley, and the top of the upper free end is connected to a steering wheel. A chain is wound on the steering wheel, one end of which is connected to the lower part of the wing plate lifting device, and the other end is connected to the trolley.

[0011] Furthermore, the wing plate lifting device, driven by the transmission device, moves back and forth linearly along the transfer beam above the wing plate loading rack and wing plate conveying mechanism on both sides.

[0012] Furthermore, the main control console is electrically connected to the wing plate cutting and blanking equipment, the web plate uncoiling machine, the web plate leveling machine, the online accompanying transverse laser cutting machine, the web plate corrugating forming machine, the corrugated web plate and wing plate conveying equipment, the flipping corrugated web plate H-beam assembly equipment, and the corrugated web plate H-beam blanking device.

[0013] Furthermore, the online following transverse laser cutting machine includes a frame, a worktable, a positioning roller group, a laser cutting head, and a dynamic adjustment system. The laser cutting head moves along the width direction of the steel plate under the drive of the linear module. The worktable is connected to the frame through the dynamic adjustment system to form a sliding pair, and achieves synchronous tracking with the movement speed of the steel plate under the precise control of the servo drive unit.

[0014] Furthermore, the dynamic adjustment system includes a servo drive unit, a transmission shaft, and a linear guide unit. The servo drive unit is dynamically coupled to the transmission shaft via a coupling. The transmission shaft and the threaded transmission sleeve in the middle of the worktable form a threaded pair. The linear guide unit is arranged parallel to the transmission shaft and forms a sliding pair with the sliding sleeve on the worktable.

[0015] The beneficial effects of this utility model are:

[0016] By sequentially setting up and integrating various production equipment onto a single production line, continuous and automated production processes are achieved, significantly improving production efficiency. The design of the wing plate transfer mechanism enables the wing plates to be automatically transferred from the wing plate temporary storage rack to the wing plate conveyor mechanism, reducing manual intervention, labor intensity, and human error.

[0017] Most importantly, the balancing mechanism effectively solves the problem of excessive axial downward load on the lifting motor in the wing plate transfer mechanism, which leads to high motor output power and high energy consumption. This helps save energy. At the same time, it extends the motor's service life and avoids equipment failure caused by motor shaft fatigue fracture.

[0018] The dynamic adjustment system of the online following transverse laser cutting machine enables synchronous tracking of the worktable and steel plate movement speeds, driving the worktable to move at the same speed as the steel plate. This effectively avoids the problem of tilting at the cut edge of the steel plate, ensuring accurate cutting by the laser cutting head during the steel plate's movement. This significantly improves the precision and quality of web plate cutting, providing a solid foundation for subsequent web plate corrugation forming and assembly with wing plates. It also reduces material waste and the increased process and time costs associated with straightening edges, thereby improving production efficiency.

[0019] The central control console provides unified control and management of the entire production line, enabling collaborative operation among various devices. It can adjust the operating parameters of each device in real time according to production needs, ensuring the efficiency, stability, and intelligence of the production process, thereby improving the consistency and stability of product quality.

[0027] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0028] Example

[0029] See Figure 1 The intelligent production line for corrugated web H-beams of this utility model includes, in sequence, a wing plate cutting and blanking device 1, a wing plate temporary storage rack 2, a web plate uncoiling machine 3, a web plate leveling machine 4, an online accompanying transverse laser cutting machine 5, a web plate corrugating forming machine 6, a corrugated web and wing plate conveying device 7, a flipping corrugated web H-beam assembly device 8, a main control console 9, and a corrugated web H-beam blanking device 10.

[0030] The wing plate cutting and blanking equipment 1 is used for high-precision oxy-acetylene flame cutting of wing plates. The cut wing plates are placed on the wing plate temporary storage rack 2 for temporary storage. The wing plate temporary storage rack 2 serves as a buffer and storage mechanism to ensure that wing plates can be supplied in a timely manner when needed in subsequent processes.

[0031] The web uncoiling machine 3 is used to unwind the web roll, providing a flat web raw material for subsequent web processing steps. The unwound web then enters the web leveling machine 4, which uses a specific rolling method to level the unwound web, eliminating stress deformation generated during the rolling process and ensuring the flatness of the web, thus providing a good foundation for subsequent cutting and corrugation forming processes.

[0032] See Figure 4 The online accompanying transverse laser cutting machine 5 includes a frame 51, a worktable 52, a positioning roller group 53, a laser cutting head 54, and a dynamic adjustment system 55. The positioning roller group 53 is used to position the web plate entering the worktable 52, ensuring the accuracy of the web plate's position during the cutting process. The laser cutting head 54 moves along the width direction of the steel plate under the drive of the linear module, enabling precise cutting of the web plate according to a preset cutting program. The worktable 52 is connected to the frame 51 via a sliding pair through the dynamic adjustment system 55, achieving synchronous tracking with the movement speed of the steel plate under the precise control of the servo drive unit.

[0033] See Figure 5 The dynamic adjustment system 55 includes a servo drive unit, a drive shaft 551, and a linear guide unit 552. The servo drive unit is dynamically coupled to the drive shaft 551 via a coupling. The drive shaft 551 and the threaded transmission sleeve in the middle of the worktable 52 form a threaded pair. The linear guide unit 552 is arranged parallel to the drive shaft 551 and forms a sliding pair with the sliding sleeve on the worktable 52. This design allows the worktable 52 to precisely adjust its position as the web moves, ensuring that the laser cutting head 54 can always cut accurately during the movement of the web, greatly improving cutting accuracy and quality.

[0034] The cut web plate enters the web plate corrugating forming machine 6. The web plate corrugating forming machine 6 processes the cut web plate into a corrugated shape through specific molds and forming processes to meet the structural requirements of corrugated web plate H-beams.

[0035] See Figure 2 The corrugated web and wing plate conveying equipment 7 is a key part of this production line. It includes a web conveying mechanism 74 located in the middle and a tilting corrugated web H-beam assembly equipment 8 for conveying the web to the next station. Wing plate conveying mechanisms 73 are provided on both sides of the web conveying mechanism 74. Wing plate loading racks 72 are provided on the outer side of the wing plate conveying mechanisms 73. Wing plate transfer mechanisms 71 are connected to the upper part of the wing plate conveying mechanisms 73 on both sides.

[0036] See Figure 3 The wing plate transfer mechanism 71 includes a transfer beam 711 mounted above the two wing plate conveying mechanisms 73. A trolley 717 is mounted on the transfer beam 711. A lifting motor 712 is mounted on the trolley. The lifting motor 712 is connected to and drives the wing plate lifting device 713 to move up and down through a transmission mechanism. The bottom of the wing plate lifting device 713 is equipped with a component for lifting the wing plate, such as an electromagnet, for adsorbing the wing plate.

[0037] See Figure 3 The trolley 717 is equipped with a balancing mechanism on one side of the upper wing plate lifting device 713 to balance the axial downward load of the lifting motor.

[0038] The balancing mechanism includes a cylinder 714 located on the outside of the wingplate lifting device 713. The fixed bottom end of the cylinder 714 is connected to a trolley 717, and the top of the free upper end is connected to a steering wheel 716. A chain 715 is wound around the steering wheel 716. One end of the chain 715 is connected to the lower part of the wingplate lifting device 713, and the other end is connected to the trolley 717. During the process of the wingplate lifting device 713 adsorbing the wingplate and moving upward, the balancing mechanism can balance the downward load of the lifting motor 712.

[0039] Driven by the transmission device, the wing plate lifting device 713 moves back and forth linearly along the transfer beam 711 on both sides of the wing plate loading rack 72 and the wing plate conveying mechanism 73, transferring the wing plates on the wing plate loading rack 72 to the wing plate conveying mechanism 73.

[0040] The flip-type corrugated web H-beam assembly equipment 8 is used to assemble corrugated webs and flanges into H-beams. This equipment uses a specific mechanical structure and flipping device to accurately align and assemble the corrugated webs and flanges together, which are then welded by a welding robot to form a compliant H-beam structure.

[0041] The H-beam blanking device 10 is used to blank the assembled H-beams, remove the finished H-beams from the production line, and complete the entire production process.

[0042] The main control console 9 is electrically connected to the following equipment: 1. Wing plate cutting and blanking machine; 3. Web plate uncoiler; 4. Web plate leveling machine; 5. Online accompanying transverse laser cutting machine; 6. Web plate corrugating forming machine; 7. Corrugated web plate and wing plate conveying equipment; 8. Tilting corrugated web plate H-beam assembly equipment; and 10. Corrugated web plate H-beam blanking device. This provides unified control and management of the entire production line. The main control console 9 can monitor the operating status of each piece of equipment in real time and adjust the operating parameters of each piece of equipment according to production needs, thereby achieving automated and intelligent control of the production process.

[0043] Working principle: At the start of production, the wing plate cutting and blanking equipment 1 cuts the wing plate, and the cut wing plate is stored on the wing plate temporary storage rack 2. Then, the wing plates stored on the wing plate temporary storage rack 2 are transferred to the wing plate loading rack 72 by crane or forklift.

[0044] Then, the lifting motor 712 of the wing plate transfer mechanism 71 drives the wing plate lifting device 713 to descend, adsorb the wing plate on the wing plate loading rack 72, and then rises, with the balancing mechanism balancing the load. Driven by the transmission device, the wing plate lifting device 713 moves along the transfer beam 711 above the wing plate conveying mechanism 73 and places the wing plate on the wing plate conveying mechanism 73.

[0045] Simultaneously, the web uncoiling machine 3 unwinds the web roll, and after being leveled by the web leveling machine 4, the web enters the online accompanying transverse laser cutting machine 5 for cutting. The dynamic adjustment system 55 of the online accompanying transverse laser cutting machine 5 synchronizes the movement speed of the worktable 52 with that of the web, and the laser cutting head 54 precisely cuts the web. The cut web then enters the web corrugating forming machine 6 to be processed into a corrugated shape.

[0046] The web plate conveying mechanism 74 and the wing plate conveying mechanism 73 respectively convey the web plate and wing plate to the tilting corrugated web H-beam assembly equipment 8 for H-beam assembly. Finally, the assembled H-beams are unloaded through the corrugated web H-beam unloading device 10, completing the entire production process. The main control console 9 monitors and adjusts the operating parameters of each device in real time to ensure the stable and efficient operation of the production line.

[0047] The above description represents a preferred embodiment of the present invention. However, the present invention is not limited to the above-described embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, all variations, equivalent substitutions, and improvements made without departing from the concept of the present invention should be included within the protection scope of the present invention.
