Description

Technical Field

[0001] This invention relates to the field of plate welding technology, and in particular to a welding machine and welding platform for plate welding. Background Technology

[0002] Prefabricated wall panel molds are mainly used to produce various precast concrete wall panels, interior partition walls, and integrated insulation and decoration wall panels. These wall panel molds consist of a surrounding frame structure to form the main frame of the mold. When welding the frame structure, the construction workers first place two long strip steel plates on the welding platform as longitudinal side beams of the frame. Then, in the interval area between the two long strip steel plates, multiple reinforcing plates are vertically welded at a preset interval. These reinforcing plates not only firmly connect the two side beams into a whole, but also serve as transverse ribs of the frame, effectively enhancing the overall structural strength and deformation resistance of the frame, and finally forming the enclosure structure of the wall panel mold. In the frame structure design of the wall panel mold, the limited overlap contact area between the reinforcing plate and the steel plate results in a thin-walled feature at the edge of the reinforcing plate. When welding this area, welding is required at the connection points between the reinforcing plate and the steel plate on both sides. If the welding torch stays on the plate for too long during the welding process, it can easily cause a high concentration of heat, melting a notch at the edge of the reinforcing plate, which directly affects the weld formation quality and connection strength. In addition, during the subsequent demolding process of the wall panel mold, it is usually necessary to apply external force to the frame structure by hammering, so that the structure can withstand a certain amount of vibration and impact. Due to the small initial contact area between the reinforcing plate and the steel plate, coupled with the possibility of quality defects in the welding area, cracks can easily occur in the weld or the base material, thereby affecting the service life of the overall structure.

[0003] To address the aforementioned problems, this application proposes a welding machine and welding platform for plate welding. Summary of the Invention

[0004] This invention proposes a welding machine and welding platform for plate welding, which solves the problems in related technologies such as small overlap area between reinforcing plates and steel plates, thin edge walls, easy overheating and melting defects during welding, and easy cracking due to small contact area and weld defects during hammer demolding, which affects the service life of the structure.

[0005] The present invention provides a welding platform for plate welding, comprising a welding platform body; The welding platform body is provided with two adjustable limiting plates, and multiple sets of push welding parts located between the two limiting plates are installed on the welding platform body. Steel plates are attached to the adjacent sides of the two limiting plates. The push-welded component includes two adjustable bidirectional cylinders. Both ends of the bidirectional cylinders are connected to L-shaped push plates. The outer side of the L-shaped push plates is magnetically attracted to an L-shaped steel plate for abutting against the steel plate. The L-shaped steel plates at both ends of the two bidirectional cylinders are symmetrically arranged. A locking area is formed between the two symmetrically arranged L-shaped steel plates. A reinforcing plate that abuts against the steel plate is placed in the locking area. The L-shaped push plate extends to both ends of the L-shaped steel plate. Both ends of the L-shaped push plate are equipped with welding parts. One welding part is used to weld the connection between the L-shaped steel plate and the steel plate body, and the other welding part is used to weld the connection between the L-shaped steel plate and the reinforcing plate.

[0006] As a further optimization of the present invention, the welding part includes an electric guide rail and a first welding gun. Both ends of the L-shaped push plate are provided with vertically arranged loading cavities. Both loading cavities are equipped with vertically arranged electric guide rails. The driving ends of the two electric guide rails are each equipped with a first welding gun. One first welding gun faces the connection between the L-shaped steel plate and the steel plate body, and the other first welding gun faces the connection between the L-shaped steel plate and the reinforcing plate.

[0007] As a further optimization of the present invention, both drive ends of the electric guide rails are equipped with air blowing sections, and the L-shaped push plate is equipped with a diversion section for conveying protective gas to the two air blowing sections.

[0008] As a further optimization of the present invention, the air blowing part includes an annular tube, and the driving ends of the two electric guide rails are each equipped with an annular tube. The flow splitting part is used to deliver the protective gas to the two annular tubes respectively. The annular tube is connected to a plurality of circumferentially arranged first air nozzles, and the first air nozzles are aligned with the orientation of the first welding torch.

[0009] As a further optimization of the present invention, the diversion section includes an intake shaft, and an intake shaft is installed at both ends of the top of the L-shaped push plate. An intake connector is connected to the top of the intake shaft, and a hose is connected to the outer periphery of both intake shafts. The two hoses are respectively connected to two annular pipes, and a second valve is installed on the hose.

[0010] As a further optimization of the present invention, the flow divider also includes an L-shaped pipe, which is connected between two intake shafts. A first valve is installed at both ends of the L-shaped pipe, and multiple spaced second air nozzles are connected to the outer path of the L-shaped pipe.

[0011] As a further optimization of the present invention, an installation groove is provided on the outer side of the L-shaped push plate, and an electromagnet for magnetically adsorbing the L-shaped steel plate is installed in the installation groove.

[0012] As a further optimization of the present invention, the push welding component also includes a first electric slide rail. A groove is provided in the middle of the top surface of the welding platform body. Multiple first electric slide rails are installed in the groove at intervals. Multiple bidirectional cylinders are respectively installed at the drive ends of the multiple first electric slide rails.

[0013] As a further optimization of the present invention, cylinder bodies are installed on both sides of the top surface of the welding platform body, and the cylinder bodies on both sides are respectively connected to two limiting plates. The two limiting plates are driven by the cylinder bodies on both sides to move closer or further apart from each other.

[0014] A welding machine for welding plates, employing the aforementioned welding platform for welding plates, includes a welding robot, a second welding torch, and a second electric slide rail; The second electric slide rail is installed on the edge of the top surface of the welding platform body, the welding robot is installed on the drive end of the second electric slide rail, and the free end of the welding robot is equipped with a second welding torch.

[0015] The above-described technical solution of the present invention has the following beneficial technical effects: 1. Adjust the distance between the two limiting plates on the main body of the welding platform according to the width of the frame structure. Place the two steel plates against the inner side of the limiting plates. In each set of push welding parts, the L-shaped push plates at both ends of the two bidirectional cylinders magnetically attract the L-shaped steel plates, driving the L-shaped push plates to push the L-shaped steel plates against the steel plate body. The symmetrically arranged L-shaped steel plates form a clamping area for placing the reinforcing plates that abut against the steel plate body. By adjusting the distance between the two bidirectional cylinders, the placement requirements of reinforcing plates of different widths can be adapted. Then, the welding parts of the L-shaped push plate edges are used to weld the connection between the steel plate body and the L-shaped steel plate, and the connection between the L-shaped steel plate and the reinforcing plate. This design improves the versatility of the device through adjustable bidirectional cylinders and L-shaped steel plates. The symmetrically arranged L-shaped steel plates enhance the rigidity and strength of the node area, avoid the thin-walled characteristics of the reinforcing plate edge, disperse welding heat to prevent edge melting gaps, improve weld quality and connection strength, and extend the service life of the wall panel mold frame structure under hammering demolding vibration impact. 2. When welding the connection between the steel plate and the L-shaped steel plate, and the connection between the L-shaped steel plate and the reinforcing plate, the protective gas can be delivered to the air blowing section on both welding sections through the diversion section. Then, the air blowing section blows air onto the connection between the steel plate and the L-shaped steel plate, and the connection between the L-shaped steel plate and the reinforcing plate. This not only allows for air blowing before welding to reduce impurities at the connection and ensure welding quality, but also forms a protective gas during welding to further ensure welding quality. The above design utilizes the diversion section and the air blowing section to achieve air blowing to remove impurities and form a protective gas before and after welding, respectively. This effectively reduces impurities in the welding area and prevents welding defects caused by impurities during welding. At the same time, the protective gas isolates the air, avoiding adverse phenomena such as oxidation, and improving welding quality. 3. When welding is required at the top connection between the L-shaped steel plate and the steel plate body, or at the top connection between the L-shaped steel plate and the reinforcing plate, the first valve in the diversion section can be opened, and the air path to the blowing section can be closed. The protective gas can be blown to the top connection between the L-shaped steel plate and the steel plate body, or at the top connection between the L-shaped steel plate and the reinforcing plate through the second air nozzle on the L-shaped tube. This achieves both air blowing to remove impurities before welding and the formation of protective gas during welding. Then, the second welding gun on the welding robot can be used to weld the top connection between the L-shaped steel plate and the steel plate body, or at the top connection between the L-shaped steel plate and the reinforcing plate. By switching the air path, the second air nozzle can blow air to remove impurities and form protective gas at the top connection, which, together with the welding robot, completes the top welding, ensuring the quality of the top welding area and further improving the integrity of the entire frame structure welding.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0019] like Figures 1-10 As shown, the present invention provides a welding platform for plate welding, comprising a welding platform body 1; The welding platform body 1 is provided with two adjustable distance limit plates 2. Multiple sets of push welding parts 3 located between the two limit plates 2 are installed on the welding platform body 1. Steel plate body 101 is attached to the adjacent side of the two limit plates 2. The push-welded component 3 includes two adjustable bidirectional cylinders 31. Both ends of the bidirectional cylinders 31 are connected to L-shaped push plates 32. The outer side of the L-shaped push plates 32 is magnetically attracted to an L-shaped steel plate 103 for abutting against the steel plate body 101. The L-shaped steel plates 103 at both ends of the two bidirectional cylinders 31 are symmetrically arranged. A locking area is formed between the two symmetrically arranged L-shaped steel plates 103. A reinforcing plate 102 that abuts against the steel plate body 101 is placed in the locking area. L-shaped push plate 32 extends to both ends of L-shaped steel plate 103. Both ends of L-shaped push plate 32 are equipped with welding parts 33. One welding part 33 is used to weld the connection between L-shaped steel plate 103 and steel plate body 101, and the other welding part 33 is used to weld the connection between L-shaped steel plate 103 and reinforcing plate 102.

[0020] During operation, first, adjust the distance between the two limiting plates 2 on the main body 1 of the welding platform according to the width of the frame structure. Then, place the two steel plates 101 against the inner sides of the two limiting plates 2. Next, magnetically attract the L-shaped steel plates 103 at both ends of the two bidirectional cylinders 31 in each set of push-welding components 3. The two bidirectional cylinders 31 drive the L-shaped pushing plates 32 at both ends to push the L-shaped steel plates 103 on them to abut against the corresponding steel plates 101. The L-shaped steel plates 103 pushed by the two bidirectional cylinders 31 are symmetrically arranged, and a locking area is formed between the symmetrically arranged L-shaped steel plates 103. A reinforcing plate 102 that abuts against the steel plate 101 is placed in the locking area. Since the distance between the two bidirectional cylinders 31 is adjustable, the two L-shaped steel plates 103 can be adjusted. The distance between the three is used to place reinforcing plates 102 of different widths. Then, the welding parts 33 at both ends of the L-shaped push plate 32 are used to weld the connection between the steel plate body 101 and the L-shaped steel plate 103, and the connection between the L-shaped steel plate 103 and the reinforcing plate 102. The symmetrically arranged L-shaped steel plates 103 can enhance the rigidity and strength of the node area between the reinforcing plate 102 and the steel plate body 101, effectively avoiding the thin-walled characteristics at the edge of the reinforcing plate 102. At the same time, the welding parts 33 are used to weld multiple connection points, which disperses the welding heat and prevents the edge of the reinforcing plate 102 from melting and leaving gaps due to excessive welding gun dwell time. This improves the weld formation quality and connection strength, thereby extending the service life of the wall panel mold frame structure under hammer demolding vibration impact.

[0021] In this embodiment, the welding part 33 includes an electric guide rail 331 and a first welding gun 332. Both ends of the L-shaped push plate 32 are provided with vertically arranged loading cavities. The two loading cavities are each equipped with a vertically arranged electric guide rail 331. The driving ends of the two electric guide rails 331 are each equipped with a first welding gun 332. One first welding gun 332 faces the connection between the L-shaped steel plate 103 and the steel plate body 101, and the other first welding gun 332 faces the connection between the L-shaped steel plate 103 and the reinforcing plate 102. During operation, two electric guide rails 331 drive two first welding torches 332 to move. One first welding torch 332 welds the connection between the L-shaped steel plate 103 and the steel plate body 101, while the other first welding torch 332 welds the connection between the L-shaped steel plate 103 and the reinforcing plate 102. Driven by the electric guide rails 331, the first welding torches 332 move vertically, ensuring that they weld connections at different heights and avoiding welding defects caused by positional deviations of the first welding torches 332.

[0022] In this embodiment, the driving ends of the two electric guide rails 331 are each equipped with an air blowing section 34, and the L-shaped push plate 32 is equipped with a diversion section 35 for conveying protective gas to the two air blowing sections 34. During operation, the diversion section 35 delivers protective gas to the blowing section 34, which is connected to the drive end of the electric guide rail 331. The blowing section 34 moves synchronously with the first welding torch 332, blowing gas to treat the weld joint before welding. During welding, protective gas is continuously output to surround the welding area. This design allows the blowing section 34 to be linked with the first welding torch 332, realizing the integrated operation of removing impurities before welding and preventing oxidation during welding, reducing the residual impurities in the welding area, avoiding oxidation of the molten pool by air, and effectively improving the welding quality.

[0023] In this embodiment, the blowing part 34 includes an annular tube 341, and the driving ends of the two electric guide rails 331 are each equipped with an annular tube 341. The diversion part 35 is used to deliver the protective gas to the two annular tubes 341 respectively. Multiple circumferentially arranged first air nozzles 342 are connected to the annular tube 341, and the first air nozzles 342 are aligned with the first welding torch 332. During operation, the distributor 35 delivers the protective gas into the annular pipe 341. The first gas nozzle 342 arranged circumferentially in the annular pipe 341 synchronously sprays the protective gas along the direction of the first welding torch 332, forming an annular gas protection area that surrounds the weld pool. This design achieves all-round spraying of the protective gas through the circumferential first gas nozzle 342, so that the weld pool is evenly surrounded by the protective gas, effectively isolating the air and avoiding defects such as porosity and slag inclusions caused by oxidation of the weld pool. At the same time, the annular air blowing can blow away impurities at the weld joint, further improving the weld formation quality.

[0024] In this embodiment, the diversion section 35 includes an intake shaft 351. Both ends of the top of the L-shaped push plate 32 are equipped with intake shafts 351. An intake connector 3511 is connected to the top of the intake shaft 351. A hose 354 is connected to the outer periphery of both intake shafts 351. The two hoses 354 are respectively connected to two annular pipes 341. A second valve 3541 is installed on the hose 354. During operation, the pipe on the protective gas delivery equipment is connected to the inlet connector 3511. The protective gas enters the inlet shaft 351 through the inlet connector 351, and then is delivered to the annular pipe 341 through the hose 354. The second valve 3541 on the hose 354 can independently control the opening and closing of the corresponding gas path and the gas flow rate. This design achieves convenient access to the protective gas through the inlet connector 3511. The hose 354 is adapted to the movement requirements of the electric guide rail 331, ensuring the smoothness of the gas path when it moves with the first welding torch 332. The second valve 3541 can independently adjust the gas supply of the two blowing sections 34 to adapt to the protective gas requirements of different welding joints and improve the flexibility of gas path control.

[0025] In this embodiment, the diversion section 35 also includes an L-shaped pipe 352, which is connected between two intake shafts 351. Both ends of the L-shaped pipe 352 are equipped with first valves 3521, and multiple spaced second air nozzles 353 are connected to the outer path of the L-shaped pipe 352. During operation, the L-shaped tube 352 connects two air intake shafts 351 to achieve gas communication. The first valves 3521 at both ends control the opening and closing of the air path of the L-shaped tube 352. When the first valve 3521 is closed, the protective gas is only delivered to the blowing section 34 through the hose 354. When the first valve 3521 is opened, the protective gas enters the L-shaped tube 352 and is sprayed out through the second nozzle 353. This design achieves the switching of the air path through the first valve 3521. The second nozzle 353 can blow air to remove impurities and provide gas protection to the top area of ​​the welded joint, making up for the lack of protection of the top area by the first nozzle 342, achieving all-round gas protection of the welding area and improving the overall welding protection effect.

[0026] In this embodiment, an installation groove is provided on the outer side of the L-shaped push plate 32, and an electromagnet 321 for magnetically adsorbing the L-shaped steel plate 103 is installed in the installation groove. During operation, the electromagnet 321 in the mounting slot of the L-shaped push plate 32 is energized and generates magnetism, magnetically attracting the L-shaped steel plate 103 to the outside of the L-shaped push plate 32. After the power is turned off, the magnetism disappears, and the L-shaped steel plate 103 can be quickly disassembled. This design achieves quick fixing and disassembly of the L-shaped steel plate 103 and the L-shaped push plate 32 through the electromagnet 321, ensuring the fit and stability of the L-shaped steel plate 103 with the L-shaped push plate 32 during the pushing and welding process, preventing the L-shaped steel plate 103 from shifting during welding and causing welding position deviation. At the same time, the magnetic connection makes it easy to replace L-shaped steel plates 103 of different specifications according to requirements, improving the adaptability of the device.

[0027] In this embodiment, the push welding component 3 also includes a first electric slide rail 36. A groove is provided in the middle of the top surface of the welding platform body 1. Multiple first electric slide rails 36 are installed in the groove at intervals. Multiple bidirectional cylinders 31 are respectively installed at the drive ends of multiple first electric slide rails 36. During operation, the first electric slide rail 36 in the groove of the welding platform body 1 drives the bidirectional cylinder 31 to move horizontally, thereby adjusting the spacing and moving the position of multiple sets of push-welding parts 3. This design achieves automated position adjustment of the push-welding parts 3 through the first electric slide rail 36, which can control the spacing between multiple sets of push-welding parts 3, adapt to the preset arrangement spacing of the reinforcing plate 102, improve the positional accuracy of the welding of the reinforcing plate 102, and at the same time, automated movement replaces manual adjustment, improving the arrangement efficiency before welding.

[0028] In this embodiment, cylinder bodies 104 are installed on both sides of the top surface of the welding platform body 1. The cylinder bodies 104 on both sides are connected to two limiting plates 2 respectively. The two limiting plates 2 are driven by the cylinder bodies 104 on both sides to move closer or further away from each other. During operation, the cylinders 104 on both sides of the welding platform body 1 extend and retract synchronously, driving the two limiting plates 2 to move closer or further apart, thereby achieving automatic adjustment of the distance between the limiting plates 2. This can adapt to the arrangement requirements of steel plates 101 of different widths, ensuring the positioning accuracy of the steel plates 101 after placement and preventing the steel plates 101 from shifting during the welding process.

[0029] A welding machine for welding plates, employing the aforementioned welding platform for welding plates, includes a welding robot 4, a second welding torch 41, and a second electric slide rail 42; The second electric slide rail 42 is installed on the edge of the top surface of the welding platform body 1, the welding robot 4 is installed on the drive end of the second electric slide rail 42, and the free end of the welding robot 4 is equipped with the second welding torch 41.

[0030] During operation, the second electric slide rail 42 on the edge of the welding platform body 1 drives the welding robot 4 to move horizontally. The free end of the welding robot 4 can flexibly adjust the welding angle and position of the second welding torch 41 to weld the top connection between the L-shaped steel plate 103 and the steel plate body 101, the top connection between the L-shaped steel plate 103 and the reinforcing plate 102, and areas that are difficult to weld. This design enables the welding robot 4 to move horizontally over a wide range through the second electric slide rail 42. Combined with the multi-degree-of-freedom operation of the welding robot 4, the second welding torch 41 can be aligned with the welding blind spot of the first welding torch 332, achieving full coverage of the plate welding area and improving the integrity of the welding. At the same time, the automated welding of the robot improves the welding efficiency and operational flexibility.

[0031] It should be noted that after the welding of the enclosure frame structure forming the wall panel mold is completed, the electromagnet 321 can be de-energized, and then the L-shaped push plate 32 can be driven away from the L-shaped steel plate 103 by the bidirectional cylinder 31, so that the welded frame structure can be removed from the welding platform body 1.

[0032] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
