Description

Technical Field

[0001] This invention relates to the field of steel mesh production technology, and more specifically, to a welding apparatus and method suitable for the production of multi-specification steel mesh. Background Technology

[0002] Reinforcing mesh is a mesh made by welding longitudinal and transverse reinforcing bars together in a cross shape. It is widely used in bridge construction, high-speed railways, and building construction. Controlling the spacing of the longitudinal reinforcing bars is a crucial step in the welding process. Existing reinforcing mesh welding machines cannot control and adjust the spacing of the reinforcing bars as needed, resulting in reinforcing meshes that do not fully meet construction requirements and thus affecting construction quality.

[0003] Regarding the aforementioned issues, Chinese Patent No. CN220971302U discloses an adjustable positioning welding device for reinforcing mesh. The welding machine includes a base and a frame mounted on the base. The frame is equipped with a pressure welding assembly and a transverse reinforcing bar unloading assembly. The longitudinal reinforcing bar conveying mechanism includes a base frame with at least two base plates. The longitudinal reinforcing bar positioning mechanism includes a longitudinal positioning beam perpendicular to the base plates. The longitudinal positioning beam is equipped with a positioning assembly for positioning and limiting the longitudinal reinforcing bars. The bottom of the longitudinal positioning beam is equipped with a sliding structure and a locking element. The base plates are equipped with multiple locking parts along the length direction. The locking element can be fixed to any locking part to adjust the distance between two longitudinal reinforcing bars.

[0004] The adjustable positioning welding device for the steel mesh provided above allows the spacing between the longitudinal positioning beams to be adjusted as needed, thereby ensuring that the spacing between the longitudinal steel bars meets the requirements.

[0005] However, although the above solution can adjust the spacing between longitudinal reinforcement bars, it relies entirely on manual operation. On the one hand, fixing the longitudinal positioning beam requires manual repeated rotation of the locking screw to screw it into the corresponding locking hole in the base plate to complete the positioning and fixing. The adjustment of multiple longitudinal positioning beams requires each one to be aligned, tightened, and verified, which is cumbersome and time-consuming. On the other hand, the positioning components used to restrain the longitudinal reinforcement bars also need to be manually adjusted and calibrated separately. The entire spacing adjustment process is complicated, time-consuming, and labor-intensive.

[0006] Therefore, developing a welding device that can automate and rapidly adjust the spacing of longitudinal steel bars, simplify the adjustment process, and reduce reliance on manual labor is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the present invention aims to provide a welding device and method suitable for the production of multi-specification steel mesh, which achieves automated and rapid adjustment of longitudinal steel bar spacing, simplifies the adjustment process, and reduces reliance on manual labor.

[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a welding device suitable for the production of multi-specification steel mesh, comprising a mesh welding machine, the mesh welding machine comprising a base, a frame, a transverse steel bar cutting assembly and several pressure welding assemblies, a receiving device provided on one side of the mesh welding machine, and a controller, the controller being electrically connected to the input end of each pressure welding assembly, a base frame provided on the side of the mesh welding machine away from the receiving device, several base plates provided on the base frame, a long base provided on the top of each base plate, a rotating shaft rotatably connected to one end of the long base, a motor connected to one of the rotating shafts, the motor being electrically connected to the controller, and a linkage part provided between the several rotating shafts; A drive rod is rotatably connected to the rotating shaft. An equidistant unfolding assembly is connected to one end of the drive rod away from the rotating shaft. The assembly includes several connecting rods, a vertical rod rotatably connected to the middle of the connecting rod, a slider fixedly connected to the lower end of the vertical rod, and a guide rail for the slider to slide. The connecting rods are rotatably connected end to end to form a continuous V-shape, and the connecting rod closest to the drive rod is rotatably connected to it. The upper ends of several of the vertical bars are provided with longitudinal reinforcement positioning blocks. The longitudinal reinforcement positioning blocks are provided with V-shaped grooves for placing the reinforcement bars. The base frame is provided with a lifting drive assembly for driving multiple base plates to lift and lower synchronously, so that the reinforcement bars placed in the V-shaped grooves are at the required height for precise docking and pressure welding of the assembly.

[0009] By adopting the above technical solution, firstly, according to the specifications of the steel mesh to be produced, the motor rotation parameters and electric push rod lifting parameters are preset in the controller; the controller controls the motor to rotate at a certain angle according to the parameters, the motor drives the rotating shaft to rotate, and through the synchronous transmission of the linkage, all rotating shafts rotate synchronously, thereby driving the drive rod to swing synchronously; the drive rod pushes multiple connecting rods to expand or retract in linkage, and the slider slides along the guide rail for stable guidance, so that all longitudinal bar positioning blocks can be adjusted synchronously at equal distances, and the motor self-locks after adjustment; the controller controls the movement of the lifting drive component according to the parameters, driving the base plate and long base to lift as a whole, adjusting the longitudinal steel bars on the longitudinal bar positioning blocks to the required welding height, ensuring that the output steel bars are accurately aligned with the pressure welding component; the controller intelligently matches the pressure welding component of the corresponding station according to the adjusted longitudinal bar spacing, individually opens the pressure welding component corresponding to the cross intersection point of the steel bar, and simultaneously closes all other non-aligned pressure welding components.

[0010] Compared to existing technologies, this application utilizes a drive rod and an equidistant unfolding assembly to achieve synchronous equidistant adjustment of all longitudinal reinforcement positioning blocks. Simultaneously, the V-grooves on the longitudinal reinforcement positioning blocks quickly locate the reinforcement positions, and the lifting drive assembly adjusts the height of the placed reinforcement, ensuring precise alignment between the output reinforcement and the pressure welding assembly. Multiple pressure welding assemblies are independently controlled for opening and closing, effectively reducing equipment energy consumption. This welding device significantly simplifies the adjustment process, quickly adapts to production requirements with different longitudinal reinforcement spacings, and improves the applicability of the welding device to multi-specification steel mesh.

[0011] The present invention is further configured such that: the lifting drive assembly includes a connecting plate disposed between the bottom of the base plate, an electric push rod disposed on the base frame, and a sliding rod slidably passing through both ends of the base plate; the electric push rod is electrically connected to the controller; the telescopic end of the electric push rod is fixedly connected to the middle of the connecting plate; and the lower end of the sliding rod is fixedly connected to the base frame.

[0012] By adopting the above technical solution, the lifting drive assembly drives the connecting plate to rise and fall via the extension and retraction of an electric push rod, causing the base plate to slide vertically along the slide bar, thus achieving stable lifting and lowering of the base plate and the overall structure above it. The slide bar acts as a guide and limiter for the base plate, ensuring no deviation and high stability during the lifting process.

[0013] The present invention is further configured such that: a limiting block is provided at the end of the guide rail away from the rotating shaft, and the limiting block can abut against the nearest slider.

[0014] By adopting the above technical solution, the limit block can limit and block the slider when it slides to the limit position, thereby limiting the maximum stroke of the connecting rod and improving the overall reliability of the equipment.

[0015] The present invention is further configured such that: the linkage part includes a driving wheel, a driven wheel and a timing belt, the driving wheel and the driven wheel are respectively fixedly sleeved on two adjacent rotating shafts, and the timing belt is sleeved between the driving wheel and the driven wheel.

[0016] By adopting the above technical solution, the synchronous rotation of multiple shafts is achieved through the linkage structure composed of the driving wheel, the driven wheel and the synchronous belt, ensuring that the actions of each equidistant unfolding component are synchronized, thereby ensuring that the spacing of the entire row of longitudinal steel bars is uniform.

[0017] The present invention is further configured such that: the cross-section of the guide rail is trapezoidal, and the slider is configured in a shape corresponding to the guide rail.

[0018] By adopting the above technical solution, the trapezoidal structure has a lateral limiting function, which can prevent the slider from shifting up and down during the sliding process, thereby ensuring the smoothness of the slider's sliding.

[0019] A welding method comprising the following steps: S1: Parameter preset: Based on the specifications of the steel mesh to be produced, preset the motor rotation parameters and electric push rod lifting parameters in the controller; S2: Automatic Spacing Adjustment: The controller controls the motor to rotate at a certain angle according to the parameters. The motor drives the rotating shaft to rotate. Through the linkage structure of the synchronous belt, the driving wheel and the driven wheel, all rotating shafts rotate synchronously, which in turn drives the drive rod to swing synchronously. The drive rod pushes multiple connecting rods to expand or retract in linkage. The slider slides along the trapezoidal guide rail for stable guidance, so that all longitudinal rib positioning blocks can be adjusted synchronously at equal distances. After the adjustment is in place, the motor self-locks. S3: Automatic height adjustment: The controller controls the extension and retraction of the electric push rod according to the parameters. The electric push rod drives the connecting plate to move vertically. Under the guidance and limiting action of the slide rod, the base plate and the long base rise and fall smoothly as a whole, adjusting the longitudinal steel bars on the longitudinal reinforcement positioning block to the required welding height, ensuring that the output steel bars are accurately aligned with the pressure welding components. S4: Adjust the number of pressure welding components: The controller intelligently matches the corresponding pressure welding components according to the adjusted longitudinal bar spacing, turns on the pressure welding components corresponding to the cross intersection of the reinforcing bars individually, and simultaneously turns off the other non-aligned pressure welding components.

[0020] In summary, the present invention has the following beneficial effects: Compared to existing technologies, this application utilizes a drive rod and an equidistant unfolding assembly to achieve synchronous equidistant adjustment of all longitudinal reinforcement positioning blocks. Simultaneously, the V-grooves on the longitudinal reinforcement positioning blocks quickly locate the reinforcement positions, and the lifting drive assembly adjusts the height of the placed reinforcement, ensuring precise alignment between the output reinforcement and the pressure welding assembly. Multiple pressure welding assemblies are independently controlled for opening and closing, effectively reducing equipment energy consumption. This welding device significantly simplifies the adjustment process, quickly adapts to production requirements with different longitudinal reinforcement spacings, and improves the applicability of the welding device to multi-specification steel mesh.
