A weld seam synchronous flattening welding apparatus and method for welding seamless aluminum windows

Abstract

This invention discloses a welding equipment and method for synchronously leveling weld seams in seamless aluminum window welding. The equipment includes a welding frame with height rods fixedly installed on both sides of the top of the frame, and a top plate fixedly installed between the two height rods. By setting up a synchronous weld seam leveling mechanism and employing a linkage structure between the welding head and the leveling roller, the invention simultaneously completes fusion welding, compaction leveling, and micro-polishing operations during the high-temperature plastic stage of the weld seam. This completely eliminates the traditional separate process of welding first and then transferring and grinding, saving the secondary shaping, grinding, and polishing processes, thus improving production efficiency and adapting to large-scale batch production. Through an adaptive clamping mechanism, a bidirectional adaptive clamping structure is adopted, combined with contour support positioning, to comprehensively constrain profile displacement, solving the problems of profile micro-slippage and misaligned splicing during high-temperature welding. This results in high weld seam splicing accuracy and a significantly improved processing tolerance.

Description

Technical Field

[0001] This invention relates to the field of seamless welding technology for aluminum alloy doors and windows, specifically to a welding equipment and method for synchronous leveling of weld seams in seamless aluminum window welding. Background Technology

[0002] Seamless aluminum windows replace the traditional corner assembly structure by integrally welding the corners of the profiles together. They have advantages such as strong sealing, excellent air tightness and water tightness, no splicing gaps at the corners, high overall aesthetics, and high structural strength. They are currently the mainstream processing technology for high-end building doors and windows.

[0003] However, traditional welding equipment has the following disadvantages: Traditional seamless aluminum window welding equipment only completes the fusion welding and forming operation. After welding, the weld has defects such as metal accumulation, surface bulges, uneven reinforcement height, and misaligned splicing edges. It must be transferred to grinding, leveling, and polishing equipment for secondary post-processing. The process is cumbersome and time-consuming. It cannot achieve integrated continuous processing, which greatly reduces the efficiency of mass production of seamless aluminum windows and results in high manual intervention costs. Summary of the Invention

[0004] The purpose of this invention is to provide a welding equipment and method for simultaneous leveling of weld seams in seamless aluminum window welding, in order to solve the problems mentioned in the background art. Traditional seamless aluminum window welding equipment only completes the fusion welding and forming operation. After welding, the weld seam has defects such as metal accumulation, surface protrusion, uneven reinforcement height, and misaligned splicing. It must be transferred to grinding, leveling, and polishing equipment for secondary post-processing. The process is cumbersome, the transfer is time-consuming, and it is impossible to achieve integrated continuous processing, which greatly reduces the efficiency of mass production of seamless aluminum windows and the cost of manual intervention is high.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding equipment for synchronously leveling weld seams in seamless aluminum window welding, comprising a welding frame, Height rods are fixedly installed on both sides of the top of the welding frame. A top plate is fixedly installed between the top of the two height rods. Two symmetrically arranged vertical plates are fixedly installed in the middle of the top of the welding frame. A screw is rotatably connected between the two vertical plates. A displacement block that is slidably connected to the welding frame is threaded in the middle of the screw. A support platform is fixedly installed at the top of the displacement block. An adaptive clamping mechanism is fixedly installed on both sides of the top of the support platform. A lead screw is rotatably connected between the two height rods. A movable block that is slidably connected to the top plate is threaded in the middle of the lead screw. A laser welding head is fixedly installed at the bottom of the movable block. Connecting frames are fixedly installed on both sides of the laser welding head. Weld seam synchronous leveling mechanism is fixedly installed at the bottom of the two connecting frames. A first pressure sensor is fixedly installed on the surface of the two weld seam synchronous leveling mechanisms. A mounting frame is fixedly installed on one side of the welding frame. A control panel is fixedly installed at the top of the mounting frame. Both of the aforementioned weld seam synchronous leveling mechanisms include an assembly plate and two synchronous frames. The two ends of one side of the assembly plate are movably connected to one end of each of the two synchronous frames, and a leveling pressure roller is rotatably connected between the two synchronous frames. Both of the adaptive clamping mechanisms include a limiting plate and a lateral locking cylinder. The middle part of the limiting plate is fixedly connected to the middle part of the lateral locking cylinder. An L-shaped frame is fixedly installed on the movable end of the lateral locking cylinder, and a pressure plate is provided at the bottom end of the L-shaped frame.

[0006] As a further technical solution of the present invention, a spot fine-tuning module and a welding speed control module are fixedly installed on both sides of the inner wall of the laser welding head. The spot fine-tuning module is adapted to fine-tune the spot size to different weld widths to ensure full welding. The welding speed control module achieves seamless welding of aluminum window corners through precise temperature and speed control, with uniform weld fusion and no defects such as incomplete welding or missing welding.

[0007] As a further technical solution of the present invention, a cylinder base is fixedly installed on the top of one side of the assembly plate, and angle cylinders are fixedly installed on both sides of the bottom end of the cylinder base. Angle blocks are rotatably connected to the movable ends of the two angle cylinders. The two angle blocks are movably connected to the opposite side of the two synchronous frames. The angle cylinders perform telescopic movements, and the angle cylinders push the angle blocks to slide along the synchronous frames. The synchronous frames rotate relative to the assembly plate to adjust the angle of the leveling roller. The surface of the leveling roller is fitted with an ultra-fine polished surface. While compacting and leveling, the weld surface is micro-polished to eliminate slag particles and uneven textures.

[0008] As a further technical solution of the present invention, the top end of the assembly plate is fixedly connected to the connecting frame, and the weld seam synchronous leveling mechanism is installed on the connecting frame through the assembly plate.

[0009] As a further technical solution of the present invention, a vertical clamping cylinder is fixedly installed at the top of the L-shaped frame. The movable end of the vertical clamping cylinder is fixedly connected to the top of the pressure plate. The bottom ends of the two limiting plates are fixedly connected to the support platform. The lateral locking cylinder performs telescopic movement and pushes the L-shaped frame from one side. The two L-shaped frames clamp and fix the product from both sides. The vertical clamping cylinder performs telescopic movement and pushes the pressure plate from the top. The two pressure plates and the support platform cooperate with each other to clamp and fix the product longitudinally.

[0010] As a further technical solution of the present invention, flexible clamping pads are laid on the bottom end of the pressure plate and one side of the L-shaped frame, and a second pressure sensor is fixedly installed on the surface of the pressure plate and the surface of the L-shaped frame. The second pressure sensor monitors the clamping pressure of the adaptive clamping mechanism in real time.

[0011] As a further technical solution of the present invention, a connecting platform is fixedly installed on one side of one of the height rods, and a stepper motor is fixedly installed on the top of the connecting platform. The output end of the stepper motor is fixedly connected to the end of the lead screw that is directly opposite to it. The stepper motor drives the lead screw to rotate. The thread on the surface of the lead screw matches the thread on the inner wall of the movable block. The movable block is limited by a top plate that matches its shape and size. Therefore, the movable block slides along the lead screw to adjust the position of the laser welding head.

[0012] As a further technical solution of the present invention, a motor base is fixedly installed inside the welding frame, and a servo motor is fixedly installed at the top of the motor base. The output end of the servo motor is fixedly connected to the end of the screw that is directly opposite to it. The servo motor drives the screw to rotate. The thread on the surface of the screw matches the thread on the inner wall of the displacement block. The displacement block is limited by the welding frame that matches its shape and size. Therefore, the displacement block slides along the screw to adjust the position of the support platform.

[0013] As a further technical solution of the present invention, two linear guide rails located on both sides of the vertical plate are fixedly installed on the welding frame. Sliding blocks are slidably connected to the middle of the two linear guide rails. The tops of the two sliding blocks are fixedly connected to the side of the support platform directly opposite to it. During the sliding process of the support platform, the sliding blocks are driven to slide along the linear guide rails, thereby improving the stability of the entire support platform.

[0014] A method for using a welding equipment for synchronous leveling of weld seams in seamless aluminum window welding includes the following steps: Step 1, Profile Positioning and Clamping: Place the aluminum window profile to be processed on the support platform, complete the precise alignment through the adaptive clamping mechanism, and complete the all-round locking and fixing of the profile. After the second pressure sensor detects that the clamping pressure reaches the standard, the clamping and positioning is completed. Step 2, Parameter Preset and Adjustment: Input the profile specifications, weld parameters, welding speed, and leveling pressure threshold through the control panel. The system will automatically match the optimal welding and leveling coordination parameters to complete the equipment parameter initialization. Step 3: Synchronous welding and leveling start: The movable block slides along the lead screw, driving the laser welding head to the starting position of the profile splicing corner. The laser welding assembly starts the fusion welding operation. At the same time, the weld seam synchronous leveling mechanism starts synchronously with the head, and the leveling pressure roller fits into the surface of the newly formed high-temperature molten weld seam. Step 4, Temperature-Controlled Adaptive Shaping: During the welding process, an external infrared temperature sensor collects the temperature of the weld pool in real time, dynamically adjusts the pressure and follow-up speed of the leveling roller, and compacts, levels, and micro-polishes the weld metal in the plastic state in real time to eliminate weld excess height and unevenness, and releases residual welding stress simultaneously. Step 5, Continuous Integrated Processing: The machine head moves continuously along the weld seam trajectory, maintaining synchronous linkage between welding and leveling throughout the process, until the corner weld fusion welding and leveling operations are all completed; Step Six: Reset and Unloading Inspection: After processing, each component automatically resets, the profile clamps are released, and the finished aluminum window is taken out. The weld surface is flat and smooth, without deformation, protrusions or depressions. No secondary grinding and shaping is required, and it can directly proceed to the next process.

[0015] Compared with the prior art, the beneficial effects of the present invention are: By setting up a synchronous leveling mechanism for weld seams and adopting a linkage structure between the welding head and the leveling roller, the welding, compaction, leveling, and micro-polishing operations are completed simultaneously during the high-temperature plastic stage of the weld seam. This completely eliminates the traditional separate process of welding first and then transporting and grinding, saving the secondary shaping, grinding, and polishing processes, improving production efficiency, and adapting to large-scale mass production. The adaptive clamping mechanism, employing a bidirectional adaptive clamping structure and contour support positioning, comprehensively constrains profile displacement, solving the problems of profile micro-slippage and misaligned splicing during high-temperature welding. This results in high weld splicing accuracy and significantly improved processing tolerance. Attached Figure Description

The threads on the surface of the lead screw 16 match the threads on the inner wall of the movable block 9. The movable block 9 is limited by the top plate 8, which matches its shape and size. Therefore, the movable block 9 slides along the lead screw 16, adjusting the position of the laser welding head 19. The laser welding assembly initiates the fusion welding operation, and simultaneously, the weld seam leveling mechanism 21 starts synchronously with the welding head. The leveling roller 216 adheres to the surface of the newly formed high-temperature molten weld seam; the angle cylinder 213 extends and retracts, pushing the angle block 214 to slide along the synchronous frame 215, while the synchronous frame 215 rotates relative to the assembly plate 211, adjusting the angle of the leveling roller 216. The surface of the leveling roller 216 is fitted with an ultra-fine polished surface, performing micro-polishing treatment on the weld seam surface while compacting and leveling, eliminating slag particles and uneven textures. During the welding process, the external... Infrared temperature sensors collect the temperature of the weld pool in real time, dynamically adjusting the pressure and follow-up speed of the leveling roller 216 to compact, level, and micro-polish the weld metal in its plastic state in real time, eliminating weld excess height and unevenness, and simultaneously releasing residual welding stress.
