Description

Technical Field

[0001] The present invention relates to the technical field of steel bar processing, and in particular to an integrated production line for welding and forming steel bar cages. Background Art

[0002] In the railway construction phase, traditional steel bar processing technology is unable to meet the growing demand for processing quality and efficiency. At present, forming a feasible set of intelligent steel bar processing equipment, processes and technical routes based on digital technology is still a complex problem. Traditional steel structure welding positioning methods mainly rely on manual visual inspection or image processing technology based on Hough transform. The manual inspection mode is inefficient, with a processing capacity of less than 20 pieces per hour, and is seriously affected by ambient light fluctuations; the traditional edge detection algorithm has a recognition rate of only about 78% for the complex cross structure formed by main bars and stirrups, and its performance drops sharply under the interference of weld spatter; the existing coordinate transformation method uses a two-dimensional plane mapping model, which does not take into account the projection distortion caused by the three-dimensional curvature of the workpiece surface, resulting in a positioning accuracy limited to the order of ±0.5mm.

[0003] In the production process of steel cages, the traditional process mode requires manual operation for loading the sun rack and threading the steel bars in the mold. This is not only inefficient but also increases the intensity of manual labor, becoming a pain point in the current production of steel cages. At the same time, the existing CNC steel cage rolling welding machines have functional limitations. They cannot realize automatic winding and automatic welding of the outer stirrups, and they also lack the technology for pre-aligning the main reinforcement of the steel cage online. In addition, in the intelligent steel cage welding and forming integrated production line, how to achieve the automated connection and coordinated work between various modules, such as the raw material storage mechanism and the automatic sawing mechanism, the main reinforcement welding mechanism and the skeleton automatic rotation mechanism, etc., to ensure the efficient operation of the entire production line, is also an urgent problem to be solved.

In this embodiment, the cage frame after initial welding can be moved to the temporary support mechanism 800 via the cage support mechanism 700, then hoisted onto the rolling welding frame 901 using a crane or other tool. The rolling welder 902 then welds the reinforcement ring to the cage frame surface.

[0080] This embodiment also provides a production method of an integrated production line for welding and forming a steel cage, which specifically includes the following steps:

[0081] S1: The steel bars are transported from the raw material storage mechanism 100 to the automatic sawing mechanism 200 for sawing. The sawn steel bars are turned over to the automatic threading mechanism 300. After the threading is completed at both ends of the steel bars, the steel bars are turned over to the main bar feeding mechanism 400.

[0082] S2: The main reinforcement feeding mechanism 400 clamps a single reinforcement bar and then transports it to the side of the skeleton automatic rotation mechanism 600;

[0083] S3: The main axis 601 of the skeleton automatic rotation mechanism 600 rotates to a predetermined angle. Stirrups are preset on the skeleton automatic rotation mechanism 600. The main reinforcement feeding mechanism 400 places a single steel bar to the corresponding position of the stirrups. The multi-axis welding robot 502 identifies the intersection of the main reinforcement and the stirrups and welds them.

[0084] S4: Repeat the S3 operation to realize the laying of main bars one by one until multiple main bars and stirrups form a rolling cage skeleton;

[0085] S5: The welded rolling cage frame is moved to the temporary support mechanism 800 for temporary storage by the frame support mechanism 700, and then the rolling cage frame is transferred to the rolling welding frame 901 of the rib welding mechanism 900 using a sling;

[0086] S6: The seam welding machine 902 conveys the wire rod steel bars on the pay-off stand device 903 according to the set pitch, and the roller cage frame rotates and the rebar feeding works in coordination with the seam welding machine 902 to complete the winding and automatic welding of the rebar.

[0087] In step S1, the raw material storage mechanism 100 stores the steel bars to be processed, and the automatic sawing mechanism 200 is docked with the raw material storage mechanism 100. During the docking process, the material can be transported individually by adding an additional automatic feeding mechanism, which delivers the steel bars and cuts them flush. This is to ensure the dimensional accuracy and consistency of the subsequent processing of the steel bars. The sawn steel bars are transferred to the automatic threading mechanism 300 through the first turning device 201. The automatic threading mechanism 300 threads the two ends of the steel bars. After the threading is completed, the steel bars are sent to the main bar feeding mechanism 400 through the second turning device 301. This series of operations realizes the automated flow of steel bars from storage to preliminary processing.

[0088] In step S2, the inclined loading rack 403 of the main reinforcement loading mechanism 400 receives the steel bars from the second turning device 301, and then sends the steel bars to the roller positioning rack 402 for positioning. Finally, the steel bars are clamped by the positioning clamping rack 401 and transported to the side of the skeleton automatic rotation mechanism 600 to ensure that the main reinforcement is in the accurate processing position for welding.

[0089] In step S3, the multi-axis welding robot 502 locates the intersection of the main reinforcement and stirrups, then welds them using CO2 gas shielded welding. This process is repeated until the multiple main reinforcements and stirrups form the cage framework, achieving automatic formation of the cage framework. The multi-axis welding robots 502 use CO2 gas shielded welding, with each robot covering three weld points on the main reinforcement. Two sets of multi-axis welding robots 502 work together to complete all welds.

[0090] In step S5, when longer steel cages are required, the cage frames must be joined together. The temporary support mechanism 800 adjusts the height of the rollers 801 via the lifting support base 802 to align the two cage frames. The joints are then welded together using the multi-axis welding robot 502 or manually, ensuring the accuracy and strength of the joints.

[0091] In step S6, the pay-off device 903 of the rebar welding mechanism 900 outputs wire rod rebar. After being straightened by the straightening mechanism, the pay-off device 903 and the rolling welding frame 901 coordinate to move and feed the rebar according to the set pitch. Simultaneously, the rolling cage frame rotates on the rolling welding frame 901, cooperating with the rebar feeding process. The rolling welder 902 automatically welds the rebar, completing the rebar winding and welding process and achieving the final shape of the rebar cage. The pitch is determined based on the rebar cage structural parameters, the wire rod diameter, and the construction strength grade specified in the design drawings. It is parameterized by a servo control system, achieving millimeter-level precision control of the rebar position. During the rebar welding process, the rolling cage frame rotates stably along its own axis via the rolling welding frame 901, spirally wrapping the rebar synchronously with the axial movement. Under pitch control, the rebar automatically adheres to the main rebar surface. Simultaneously, the rolling welder 902, fixed to the end of the welding arm, performs continuous welding at the intersections between the rebar and the main rebar, achieving an integrated operation of rebar placement and automated welding.
