Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically a welding machine for door and window manufacturing. Background Technology

[0002] Welding machines for door and window production and processing are specially designed for door and window manufacturing. They are used to process door and window profiles such as aluminum alloy, PVC, and stainless steel. Through welding processes, mechanical structures are used to achieve functions such as profile positioning, welding head movement, and welding area cooling. The profile interfaces of door and window frames are fused and fixed to form a complete and sturdy door and window frame structure.

[0003] The basic structure of a traditional welding machine for door and window production includes a fixed frame for welding profiles, a single-axis moving welding head, a bolt-clamped manual positioning fixture, and a water-cooling system for the welding head. The working principle is that the door and window profiles are fixed on the machine's worktable by the manual positioning fixture. The single-axis moving welding head moves linearly along the length of the profile. The integrated internal components complete the wire feeding and arc welding. At the same time, a single water-cooling system cools the welding head. The welding process requires manual monitoring and adjustment. Finally, the profile interface is fused to form the door and window frame.

[0004] Traditional welding machines used in door and window manufacturing lack dedicated auxiliary guidance and drag reduction structures in the profile movement and positioning stages. They rely solely on manual labor to move the profiles to the workbench and manually align them with the positioning reference. This results in a lack of stable trajectory constraints during profile movement, making them susceptible to factors such as the flatness of the workbench surface and uneven weight distribution of the profiles, leading to deviations, jamming, or tilting. Furthermore, manual handling requires overcoming the sliding friction between the profiles and the workbench, increasing the operator's workload and making it difficult to ensure consistent force and speed for each move. This results in significant fluctuations in profile positioning accuracy. This manual movement and positioning method prolongs the positioning time for a single profile and reduces the overall welding efficiency, especially in the mass production of door and window frames, where the problem of low positioning efficiency is even more pronounced. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a welding machine for door and window production and processing, which solves the problems of traditional welding machines relying on manual labor in the profile movement and positioning process, lacking auxiliary guidance and drag reduction structures, resulting in easy profile deviation and jamming, and high labor intensity for operators.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A welding machine for door and window manufacturing includes a base, a worktable fixedly connected to the top of the base, a frame fixedly connected to the top of the worktable, a support column fixedly connected inside the frame, a rear cover fixedly connected to the outer wall of the frame, a height adjustment component inside the support column, a pair of positioning blocks symmetrically fixedly connected to the top of the worktable, a groove formed on the top of the worktable, a rotating rod rotatably connected inside the groove, a rotating ring fixedly connected to the outside of the rotating rod, an adsorption component inside the frame, a guide column fixedly connected to the top of the worktable, a guide ring rotatably connected to the outside of the guide column, sealing components on both sides of the frame, an observation glass installed on the side of the frame away from the rear cover, a buffer clamping component on the top of the worktable, a connecting block installed on the side of the height adjustment component away from the rear cover, a welding head and a wire feed head installed at the bottom of the connecting block, a wire feed chamber fixedly connected to the top of the worktable, the wire feed chamber and the wire feed head connected via a pipe, a control panel fixedly connected to the outer wall of the base, and a rotating component inside the connecting block.

[0007] Preferably, the buffer clamping assembly includes an electric actuator, which is uniformly and fixedly connected to the top of the worktable. The output end of the electric actuator is fixedly connected to a mounting block, and a pressure block is slidably connected inside the mounting block. A spring is fixedly connected between the mounting block and the pressure block.

[0008] Preferably, the rotating assembly includes a motor, which is fixedly connected to the outer wall of the connecting block. The output end of the motor is fixedly connected to a rotating shaft, and a connecting rod is fixedly connected to the outside of the rotating shaft.

[0009] Preferably, the adsorption assembly includes a filter chamber, which is fixedly connected to the side of the rear cover away from the frame. A suction pump is fixedly connected to the top of the filter chamber, and an input pipe is fixedly connected to the input end of the suction pump. An adsorption cover is installed on the frame, and an output pipe is installed at the bottom of the filter chamber.

[0010] Preferably, the height adjustment assembly includes a hydraulic rod, which is fixedly connected to the top of the support column. A lifting block is fixedly connected to the output end of the hydraulic rod. A limit groove is formed inside the support column, and the lifting block is slidably connected inside the limit groove.

[0011] Preferably, the sealing assembly includes an electric actuator two, which is installed on the top of the frame. The output end of the electric actuator two is fixedly connected to a sealing door. A sliding groove is provided inside the frame, and the sealing door is slidably connected inside the sliding groove.

[0012] Preferably, both the rotating rod and the rotating ring are rotatably connected inside the groove, and the positions of the rotating ring and the guide ring are adapted to the position of the positioning block.

[0013] Preferably, a buffer pad is uniformly and fixedly connected to the bottom of the pressure block, and the buffer pad is positioned directly above the positioning block.

[0014] Preferably, the connecting rod is fixedly connected to the top of the welding head on the side away from the connecting block, and the wire feed head is installed on the right side of the welding head.

[0015] Preferably, the end of the input pipe away from the suction pump is fixedly connected to the top of the adsorption cover, and the adsorption cover is positioned directly above the workbench.

[0016] This invention provides a welding machine for door and window manufacturing. It has the following advantages: 1. This invention drives the rotating rod and ring to rotate during the conveying of the door and window profiles to be processed. At the same time, the guide ring guides the profiles, making them move smoothly along a preset trajectory. Compared with the existing technology where manual handling of profiles is prone to deviation and jamming, this invention achieves precise trajectory control and reduces friction during the profile movement process. This helps to reduce the manual force required to push the profiles, shortens the profile positioning time, and lays the foundation for subsequent welding operations.

[0017] 2. After the profile is positioned, the electric push rod pushes the mounting block down, causing the buffer pad at the bottom of the pressure block to fit against the profile surface. When the electric push rod applies force continuously, the spring is compressed to generate a uniform elastic clamping force. Compared with the existing bolt-clamping manual clamps, which require repeated manual adjustment of the force and are prone to profile deformation or loosening, this invention achieves automated profile clamping and elastic buffer protection. It helps to avoid damage to the profile caused by rigid clamping, improves clamping efficiency, and is compatible with door and window profiles of different thicknesses, indirectly ensuring the welding accuracy of the profile interface.

[0018] 3. Before welding, the invention uses an electric push rod to lower the sealing door along the slide groove to form a closed welding space. The suction pump starts and draws in the fumes through the input pipe and the suction cover. After being filtered by the filter chamber, the clean gas is discharged from the output pipe. Compared with the existing technology where welding machines do not have fume treatment or simple fume exhaust devices that lead to the spread of fumes, this invention achieves efficient collection and purification of welding fumes, which helps to avoid fumes polluting the working environment and reduce the harm to the respiratory tract of operators.

[0019] 4. This invention uses a hydraulic rod to push the lifting block to slide along the limiting groove, thereby driving the connecting block, welding head, and wire feeding head to adjust the welding height. The motor drives the rotating shaft and connecting rod to deflect and adjust the welding head angle. Compared with the traditional single-axis moving welding head in the prior art, which requires frequent disassembly and adjustment and is difficult to adapt to welding of various interfaces, this invention realizes flexible and automated adjustment of welding height and angle, which helps to improve the equipment's adaptability to different door and window styles and reduce operation time costs.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 -Appendix Figure 5 This invention provides a welding machine for door and window manufacturing, including a base 1, a worktable 2 fixedly connected to the top of the base 1, a frame 3 fixedly connected to the top of the worktable 2, a support column 16 fixedly connected inside the frame 3, a back cover 4 fixedly connected to the outer wall of the frame 3, a height adjustment component 8 disposed inside the support column 16, a pair of positioning blocks 10 symmetrically fixedly connected to the top of the worktable 2, a groove 11 formed on the top of the worktable 2, a rotating rod 12 rotatably connected inside the groove 11, a rotating ring 13 fixedly connected to the outside of the rotating rod 12, an adsorption component 7 disposed inside the frame 3, and a guide column 14 fixedly connected to the top of the worktable 2, with a [missing information - likely a component or component] rotatably connected to the outside of the guide column 14. The guide ring 15 and the frame 3 are both equipped with sealing components 9. The side of the frame 3 away from the rear cover 4 is equipped with an observation glass 22. The top of the worktable 2 is equipped with a buffer clamping component 5. The side of the height adjustment component 8 away from the rear cover 4 is equipped with a connecting block 17. The bottom of the connecting block 17 is equipped with a welding head 18 and a wire feeding head 20. The top of the worktable 2 is fixedly connected with a wire feeding chamber 19. The wire feeding chamber 19 and the wire feeding head 20 are connected by a pipe. The outer wall of the base 1 is fixedly connected with a control panel 21. The connecting block 17 is equipped with a rotating component 6. The rotating rod 12 and the rotating ring 13 are rotatably connected inside the groove 11. The positions of the rotating ring 13 and the guide ring 15 are adapted to the positions of the positioning block 10.

[0024] Specifically, welding process parameters are pre-set via control panel 21, eliminating the need for manual adjustments. Parameter setting is fast and accurate, solving the problems of low efficiency and error-proneness associated with traditional manual parameter adjustment. Next, the door and window profiles to be processed are fed onto the worktable 2 via guide ring 15. After being placed in the preset position on worktable 2, positioning block 10 initially holds the profile in place, preventing it from moving arbitrarily. This is much better than the traditional method where the profile is easily misaligned without initial restraint. Then, as the profile moves, rotating rod 12 rotates, causing rotating ring 13 to rotate. Rotating ring 13 and guide ring 15 work together to smoothly move the profile to its designated location along the trajectory, eliminating the need for forceful pushing and the risk of deviation. The device then enters the standby state. This method not only solves the shortcomings of traditional manual profile handling, which is laborious and prone to deviation, but also, through the cooperation of guide ring 15, rotating rod 12, rotating ring 13, and positioning block 10, makes profile movement more stable and positioning faster, while reducing the hassle of manual operation and greatly improving the positioning efficiency and accuracy of the welding machine.

[0025] Please see the appendix Figure 3 -Appendix Figure 6The buffer clamping assembly 5 includes an electric push rod 51, which is uniformly and fixedly connected to the top of the worktable 2. The output end of the electric push rod 51 is fixedly connected to a mounting block 52. A pressure block 53 is slidably connected inside the mounting block 52. A spring 55 is fixedly connected between the mounting block 52 and the pressure block 53. A buffer pad 54 is uniformly and fixedly connected to the bottom of the pressure block 53. The buffer pad 54 is positioned directly above the positioning block 10.

[0026] Specifically, by activating the electric actuator 51, the actuator outputs power to push the mounting block 52 downward. The mounting block 52 drives the internal pressure block 53 to descend synchronously, ensuring that the buffer pad 54 at the bottom of the pressure block 53 precisely fits against the profile surface. As the electric actuator 51 continues to apply force, the spring 55 between the mounting block 52 and the pressure block 53 gradually compresses. The elastic properties of the spring 55 create a buffering effect, effectively preventing excessive compression damage to the profile due to excessive clamping force. During this process, the elastic clamping force generated by the spring 55 acts evenly on the profile, stably fixing it on the worktable 2. This provides a stable clamping foundation for subsequent welding operations, reducing the possibility of welding deviations due to profile displacement. This method simplifies the clamping operation process, eliminating the need for repeated manual adjustments and improving clamping efficiency to a certain extent. On the other hand, the elastic buffering of the spring 55 and the protective effect of the buffer pad 54 reduce the risk of profile clamping damage while ensuring clamping stability, which helps to improve the quality stability of welding operations.

[0027] Please see the appendix Figure 1 -Appendix Figure 6 The rotating component 6 includes a motor 61, which is fixedly connected to the outer wall of the connecting block 17. The output end of the motor 61 is fixedly connected to a rotating shaft 62. A connecting rod 63 is fixedly connected to the outside of the rotating shaft 62. The side of the connecting rod 63 away from the connecting block 17 is fixedly connected to the top of the welding head 18. The wire feed head 20 is installed on the right side of the welding head 18.

[0028] Specifically, after receiving a control signal, the motor 61 drives the rotating shaft 62 to rotate. The rotating shaft 62 synchronously drives the externally fixed connecting rod 63 to deflect. During the deflection process, the connecting rod 63 directly drives the welding head 18 to adjust to the angle that matches the profile interface. This ensures that the welding head 18 can fully cover the profile interface during welding operations. This process does not require manual intervention to adjust the angle of the welding head 18, which solves the shortcomings of the traditional manual adjustment of the welding head 18 angle, which is cumbersome and inefficient. To a certain extent, it improves the problems of large angle deviation and incomplete welding coverage in the traditional adjustment method, and provides support for improving the welding quality of profile interfaces.

[0029] Please see the appendix Figure 2 and attached Figure 7The adsorption assembly 7 includes a filter chamber 71, which is fixedly connected to the side of the rear cover 4 away from the frame 3. A suction pump 72 is fixedly connected to the top of the filter chamber 71, and an input pipe 73 is fixedly connected to the input end of the suction pump 72. An adsorption cover 74 is installed on the frame 3. An output pipe 75 is installed at the bottom of the filter chamber 71. The end of the input pipe 73 away from the suction pump 72 is fixedly connected to the top of the adsorption cover 74. The adsorption cover 74 is located directly above the workbench 2.

[0030] Specifically, after the suction pump 72 is started, a negative pressure is generated. Through the dust collection channel formed by the input pipe 73 and the adsorption cover 74, the dust generated during the welding process is sucked into the filter chamber 71. After the dust is filtered in the filter chamber 71, the clean gas is discharged to the outside through the output pipe 75. This process not only solves the shortcomings of the unorganized emission of dust from traditional welding machines, but also effectively collects and filters welding dust, reducing the pollution of dust to the working environment to a certain extent and creating relatively healthier working conditions for operators.

[0031] Please see the appendix Figure 3 and attached Figure 4 The height adjustment component 8 includes a hydraulic rod 81, which is fixedly connected to the top of the support column 16. The output end of the hydraulic rod 81 is fixedly connected to a lifting block 82. A limit groove 83 is opened inside the support column 16, and the lifting block 82 is slidably connected inside the limit groove 83.

[0032] Specifically, by activating the hydraulic rod 81, the hydraulic rod 81 outputs driving force to push the lifting block 82, causing the lifting block 82 to slide stably along the limiting groove 83. During the sliding process, the lifting block 82 simultaneously drives the connecting block 17 to descend. The connecting block 17 further drives the welding head 18 and the wire feeding head 20 at the bottom to move together until the welding head 18 and the wire feeding head 20 are adjusted to the height required for welding the profile. This method improves the problem of large height deviation in the traditional adjustment method to a certain extent, and provides basic support for the subsequent accurate feeding of welding wire and stable welding.

[0033] Please see the appendix Figure 2 and attached Figure 8 The sealing assembly 9 includes an electric actuator 91, which is mounted on the top of the frame 3. The output end of the electric actuator 91 is fixedly connected to a sealing door 92. A groove 93 is provided inside the frame 3, and the sealing door 92 is slidably connected inside the groove 93.

[0034] Specifically, by activating the electric actuator 91, the electric actuator 91 outputs driving force according to the operation requirements: when the sealing door 92 needs to be closed, the electric actuator 91 pushes the sealing door 92 to slide downward along the slide groove 93 until the sealing door 92 completely covers the openings on both sides of the frame 3, forming a sealed welding space; when the sealing door 92 needs to be opened, the electric actuator 91 pulls the sealing door 92 upward along the slide groove 93 in the opposite direction, so that the openings on both sides of the frame 3 are completely open, making it convenient to pick up and put down the profile. This method reduces the gaps in the sealed space to a certain extent, providing more favorable conditions for subsequent dust collection.

[0035] Working principle: Before the device is started, the welding process parameters are preset through the control panel (21). The door and window profiles to be processed are transported by the guide ring (15) and placed in the preset position on the workbench (2). The positioning block (10) initially limits the profile. During the movement of the profile, the rotating rod (12) drives the rotating ring (13) to rotate. The rotating ring (13) and the guide ring (15) work together to help the profile to be smoothly placed in place, and the device enters the standby state. Then, the electric push rod (51) is started to push the mounting block (52) down, so that the bottom buffer pad (54) of the pressure block (53) fits against the surface of the profile. As the electric push rod (51) continues to apply force, the spring (55) is compressed to generate elastic buffer, preventing over-extrusion, and thus the profile is stably fixed on the workbench (2) to avoid welding displacement. During the welding preparation stage, the control panel (21) instructs the electric actuator (91) to work, pushing the sealing door (92) down along the slide (93) to close the welding area; at the same time, the suction pump (72) runs, forming a negative pressure with the suction cover (74) through the input pipe (73) to prepare for collecting welding fumes; then, the hydraulic rod (81) is started to push the lifting block (82) to slide along the limit groove (83), driving the connecting block (17) down, so that the welding head (18) and the wire feed head (20) are adjusted to the welding height, and the wire feed chamber (19) delivers the welding wire to the wire feed head (20) through the pipeline, completing the pre-welding preparation; When welding is performed, the welding head (18) is activated to generate a welding arc, and the wire feeder (20) feeds the welding wire to the welding area to achieve the fusion of the profile interface; when the angle of the welding head (18) needs to be adjusted, the motor (61) drives the rotating shaft (62) to rotate, which drives the connecting rod (63) to deflect, thereby adjusting the angle of the welding head (18) to ensure that the welding covers the profile interface; the fumes generated during the welding process are sucked into the filter chamber (71) by the suction pump (72) through the adsorption cover (74) and the input pipe (73), and the filtered gas is discharged through the output pipe (75) to avoid fumes pollution; After a single profile is welded, the welding head (18), wire feeder (20), and suction pump (72) stop in sequence. The motor (61) drives the welding head (18) to reset. The hydraulic rod (81) drives the connecting block (17) and the welding head (18) to rise to a safe height. Then, the electric push rod two (91) is started to pull the sealing door (92) to rise and open along the slide groove (93). The electric push rod one (51) drives the mounting block (52) and pressure block (53) to rise, release the profile clamp, and the operator takes out the welded profile. The device waits for the next operation instruction.
