Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum alloy door and window production and processing, and particularly relates to a welding equipment for aluminum profile processing. BACKGROUND

[0002] Aluminum alloy doors and windows are a popular choice for modern building decoration, and have obvious advantages. The material is based on aluminum, with the addition of various alloy elements. It is light in texture but strong and durable, and has strong corrosion resistance, is not afraid of erosion in a humid environment, and can maintain good performance for a long time. There are many places for aluminum profile welding in the production process of aluminum alloy doors and windows. At present, most aluminum profiles are welded by semi-manual and semi-mechanical or completely manual welding with a welding gun. Moreover, in actual processing, it is difficult to weld the two ends of the aluminum-clad profile.

[0003] Because the cross-section of the aluminum profile has many internal lines after extrusion molding, for example, the aluminum profile is designed to have a honeycomb shape and a porous shape, so that the aluminum profile is lightweight and has a strong structure. However, traditional welding can only weld the periphery of the aluminum profile, and the internal part cannot be effectively fused and welded. For aluminum profiles with complex cross-sectional lines, the welding gun cannot be controlled to penetrate the surface, and thus effective welding cannot be achieved. This limits the welding of aluminum profiles, and it is difficult to ensure that the interface is completely attached and uniform during butt welding, which affects the stability of the welding quality.

[0019] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The welding equipment for aluminum profile processing according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0021] like Figure 2 and Figure 3 As shown, the welding equipment for aluminum profile processing provided in this embodiment of the invention includes a welding mechanism 4. The welding mechanism 4 includes a welding furnace assembly 41, a hot melt assembly 44, and an electric heating assembly. The hot melt assembly 44 and the electric heating assembly are both disposed inside the welding furnace assembly 41.

[0022] The welding furnace assembly 41 includes a furnace body 412 and a heating chamber 413. The heating chamber 413 is located inside the furnace body 412, and the inner wall of the heating chamber 413 is provided with an insulating heat-insulating lining 411 made of insulating material. The hot melting assembly 44 includes a heating coil 442, which is located in the middle of the inner wall of the heating chamber 413. The electric heating assembly includes electrode sleeves 45 located at both ends of the heating chamber 413.

[0023] Specifically, during the butt welding process of aluminum profiles, the two aluminum profiles to be welded are first inserted into the heating chamber 413 from the inlet and outlet 43 at both ends of the furnace body 412, and the butt joint of the aluminum profiles is aligned with the heating coil 442, with the two ends of the aluminum profiles tightly attached to each other. Then, the two aluminum profiles are fixed and electrode sleeves 45 are installed on them respectively.

[0024] After the aluminum profiles are fixed, the heating coil 442 is energized to heat the joint of the aluminum profiles to near the melting temperature (below the melting point of the aluminum profiles). The heat insulation lining 411 in the heating chamber 413 provides good heat insulation and electrical insulation. Then, the electrode sleeve 45 is energized to connect the two aluminum profiles to the power supply respectively. The contact area of ​​the two aluminum profiles is further heated and melted due to the short circuit, which can fully fuse the welding surfaces 7 at both ends of the aluminum profiles and improve the welding quality.

[0025] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, heating coil 442 is wound around the outer wall of heating base 446, and preheating coil 441 is provided on both sides of heating base 446. Both heating coil 442 and preheating coil 441 are electromagnetic heating coils. The output power of heating coil 442 is greater than that of preheating coil 441. Heating base 446 is provided in the middle of heating chamber 413. Heating base 446 is made of graphite silicon carbide ceramic material.

[0026] Specifically, in order to ensure that the butt welding position of the aluminum profile is heated evenly, the electromagnetic field generated by the heating coil 442 can easily pass through the heating seat 446 made of graphite silicon carbide ceramic material and act on the aluminum profile. The electromagnetic field causes eddy currents to be generated on the welding surface 7 of the aluminum profile, thereby heating the contact surface of the aluminum profile. In addition, the preheating coils 441 on both sides of the heating coil 442 preheat both sides of the welding end of the aluminum profile to prevent excessive deformation of the welding part due to excessive temperature difference.

[0027] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the heating base 446 is provided with welding liquid overflow grooves 445 at both ends, and scrapers 444 are provided on both sides of the welding liquid overflow grooves 445.

[0028] Specifically, after the aluminum profile welding area melts, the molten aluminum overflows into the weld overflow grooves 445 on both sides of the heating base 446. During the process of the aluminum profile being pulled out of the heating chamber 413 after welding, the solder is scraped by the scraper 444 to trim the side of the aluminum profile weld, making the side wall of the aluminum profile smoother after welding.

[0029] In one embodiment of the present invention, such as Figure 3 and Figure 4As shown, a welding liquid tank 482 is provided in the middle of the inner wall of the heating base 446. A welding liquid discharge tank 443 is provided through the inner and outer walls of the furnace body 412. The welding liquid discharge tank 443 is connected to the welding liquid overflow tank 445 and the welding liquid tank 482. A waste tank 42 is provided on the outside of the furnace body 412 to cover the welding liquid and prevent it from splashing. The welding liquid discharge tank 443 is connected to the waste tank 42. The waste tank 42 is a detachable structure. A buckle 421 is provided on the waste tank 42 to facilitate timely cleaning of the welding material in the waste tank 42 later.

[0030] Specifically, the welding liquid tank 482 facilitates the timely discharge of welding liquid overflowing from the welding surface 7 during the welding process, making the welding liquid flow more smoothly and the welding liquid distribution on the welding surface 7 more uniform. The welding liquid outside the welding liquid tank 482 will flow to the welding liquid overflow tank 445, and finally the overflowing welding liquid will flow out to the waste tank 42 through the welding liquid discharge tank 443, reducing the welding liquid residue on the surface of the aluminum profile during the welding process.

[0031] In one embodiment of the present invention, such as Figure 3 , Figure 5 and Figure 7 As shown, the welding slurry tank 482 is equipped with a wire feeding assembly 48 for feeding welding wire into the welding slurry tank 482. The wire feeding assembly 48 includes a wire feeding shell 481, a wire feeding wheel 484, a welding wire roll 485, and a wire feeding head 483. The wire feeding shell 481 is located outside the furnace body 412. One end of the wire feeding head 483 is connected to the wire feeding shell 481, and the other end passes through the welding slurry tank 482. The welding wire roll 485 is located inside the wire feeding shell 481. The wire feeding wheel 484 is located between the welding wire roll 485 and the wire feeding head 483 for feeding the welding wire on the welding wire roll 485 out of the wire feeding head 483.

[0032] The wire feed head 483 is provided with a centering push rod 46 on the outside. The centering push rod 46 is used to adjust the wire feeding position of the wire feed head 483 and to center the welding surface 7 of the two aluminum profiles to the middle position of the heating base 446.

[0033] Specifically, during the welding process, to ensure the molten solder is fully distributed on the welding surface 7, after the aluminum profiles are joined, the wire feed head 483 is fed to the center position of the welding surface 7 via the centering push rod 46 (it should be noted that, to ensure the wire feed head 483 does not affect the electrical contact between the two aluminum profiles, the wire feed head 483 is made of a conductive material, or a slot to accommodate the wire feed head 483 is pre-reserved on the welding surface 7 of the aluminum profiles). Figure 7 As shown, the wire feeder 483 feeds out the welding wire and melts it into welding liquid. The welding liquid flows out from the middle of the welding surface 7 and then drives the aluminum profile to rotate through the centrifugal mechanism 5. In this way, the welding liquid is evenly distributed on the welding surface 7 under the action of centrifugal force. Finally, the excess welding liquid is discharged from the welding liquid tank 482 or the welding liquid overflow tank 445.

[0034] During the wire feeding process, the welding wire on the wire coil 485 is continuously driven into the wire feeding head 483 by the wire feeding wheel 484. The bottom end of the wire feeding housing 481 is provided with a cover plate 487 to facilitate the removal of the welding wire coil 485 from the spool 486.

[0035] In one embodiment of the present invention, such as Figure 2 , Figure 3 and Figure 7 As shown, centrifugal mechanisms 5 are provided at both ends of the furnace body 412 to drive its centrifugal rotation, so as to make the welding liquid evenly distributed on the edge part of the aluminum profile welding surface 7. The centrifugal mechanism 5 includes a centrifugal rotating seat 51, a drive gear plate 52 and a drive motor 53. The drive gear plate 52 is provided at both ends of the furnace body 412, the centrifugal rotating seat 51 is sleeved on the edge part of the drive gear plate 52, and a gear head 54 is provided on the power shaft of the drive motor 53. The gear head 54 meshes with the gear of the drive gear plate 52.

[0036] Specifically, in order to ensure that the welding liquid is fully distributed on the welding surface 7, the drive motor 53 drives the gear head 54 to rotate, which in turn drives the drive gear disk 52 to rotate. The rotation of the gear disk drives the entire furnace body 412 to rotate in the centrifugal rotating seat 51, which in turn drives the aluminum profile to rotate along its axis.

[0037] After the welding wire flows out from the middle of the welding surface 7, it is heated and melted into welding liquid. The welding liquid is spread out from the middle of the welding surface 7 by centrifugal force, so that the welding liquid can be distributed from the inside to the outside of the welding surface 7, thereby improving the overall welding strength of the welding surface 7.

[0038] In one embodiment of the present invention, such as Figure 2 , Figure 3 As shown, clamping adjustment mechanisms 3 are provided on both sides of the furnace body 412 for adjusting the position between two welded aluminum profiles. The mechanism includes a clamping base 31, a clamping sleeve 32, and an adjustment track 36. A base 1 is provided at the bottom of the furnace body 412. The adjustment track 36 is provided between the clamping base 31 and the base 1. The clamping sleeve 32 is rotatably provided inside the clamping base 31. A support rod 37 is provided between the clamping base 31 and the adjustment track 36. A clamping base 35 is provided at the bottom of the support rod 37.

[0039] A material passage groove 34 is provided on the inner side of the clamping sleeve 32. A locking component 33 is provided on the clamping sleeve 32. The locking component 33 can be a locking electric cylinder. The outer surface of the aluminum profile is clamped by the extension and retraction of the locking electric cylinder. An elastic conveyor belt 341 is provided between the material passage groove 34 and the heating chamber 413.

[0040] Specifically, the clamping adjustment mechanism 3 can adjust the position of the aluminum profile relative to the furnace body 412, so that the two ends of the aluminum profile are tightly attached. Specifically, after the locking component 33 on the clamping sleeve 32 clamps the aluminum profile, the distance between the clamping sleeve 32 and the furnace body 412 can be adjusted by the adjustment track 36 at its bottom, thereby controlling the position of the aluminum profile entering the furnace body 412 and ensuring that the two ends of the aluminum profile are tightly attached during the aluminum profile welding process. Alternatively, the two adjustment tracks 36 on the left and right sides of the furnace body 412 can work together to control the length change of the aluminum profile during the welding process.

[0041] The clamping adjustment mechanism 3 can also push the welded aluminum profile to move left and right, so that the outer wall of the welding surface 7 can fully contact the scraper 444, and the outer wall of the welding surface 7 can be cleaned and made more regular. The elastic conveyor belt 341 between the material passage 34 and the heating chamber 413 keeps the material passage 34 and the heating chamber 413 synchronized. On the one hand, it facilitates the smooth entry of the aluminum profile from the material passage 34 into the heating chamber 413, and on the other hand, it can adapt to the changes in the distance between the clamping sleeve 32 and the furnace body 412.

[0042] In one embodiment of the present invention, such as Figure 2 and Figure 6 As shown, a feeding mechanism 2 is provided on the side of the clamping base 31 away from the furnace body 412. The feeding mechanism 2 includes a feeding track 21, a feeding cart 22 and a clamp 23. The feeding track 21 is provided on the side of the clamping base away from the furnace body 412, the feeding cart 22 is provided in the feeding track 21, and the clamp 23 is provided on the top of the feeding cart 22.

[0043] Specifically, the aluminum profile to be welded is laid horizontally in the clamp 23. After the clamp 23 clamps the aluminum profile, the aluminum profile is sent into the furnace body 412 by the feeding cart 22. Alternatively, the welded aluminum profile can be transferred out of the furnace body 412 through the above operation, which facilitates the feeding and unloading of aluminum profiles during the welding process.

[0044] In one embodiment of the present invention, such as Figure 3 and Figure 6 As shown, a positioning control rod 47 is provided below the furnace body 412, and a positioning sensor 471 corresponding to the positioning control rod 47 is provided on the outer wall of the furnace body 412.

[0045] Specifically, in order to keep the aluminum profile in a horizontal position during the process of entering and exiting the furnace body 412, after the centrifugal rotation of the furnace body 412 is completed, the drive motor 53 drives the furnace body 412 to rotate slowly. When the positioning sensor 471 on the outer wall of the furnace body 412 is aligned with the positioning control rod 47, the positioning control rod 47 controls the motor to stop rotating and lock, so that the aluminum profile is kept in a horizontal position during the process of entering and exiting the furnace body 412, which facilitates the feeding and unloading of the aluminum profile.

[0046] To clearly illustrate the above embodiments, refer toFigures 1-7 The specific working principle of the welding equipment for aluminum profile processing of the present invention is as follows: When performing butt welding of aluminum profiles, the first step is to place the two aluminum profiles to be welded horizontally in the clamp 23. After the clamp 23 firmly clamps the aluminum profiles, the aluminum profiles are transported to the clamping sleeve 32 by the feeding cart 22. The aluminum profiles are further transported to the heating chamber 413 of the furnace body 412 through the clamping sleeve 32. The two aluminum profiles are simultaneously inserted into the heating chamber 413 from both ends of the furnace body 412.

[0047] After the aluminum profiles are joined in the heating chamber 413, the locking assembly 33 on the clamping sleeve 32 quickly clamps the aluminum profiles. Simultaneously, the clamping sleeve 32 precisely adjusts the joining position of the aluminum profiles via the adjusting rail 36 at the bottom, ensuring complete alignment with the center of the heating base 446. At this point, the centering push rod 46 pushes the wire feed head 483 to the exact center of the welding surface 7 of the aluminum profile. Next, the two aluminum profiles are fixed in place, and electrode sleeves 45 are installed on each.

[0048] After the aluminum profile is properly fixed, the heating coil 442 is energized to heat the butt joint of the aluminum profile to a near-melting temperature (this temperature must be higher than the melting point of the welding wire). At the same time, the preheating coil 441 is used to preheat both sides of the welding surface 7. Subsequently, the wire feeder 483 continuously feeds out the welding wire, which quickly melts into molten welding after entering the heating seat 446 (note that the melting point of the welding wire is usually lower than that of the welding metal so that the molten welding can flow smoothly in the weld).

[0049] As the molten welding fluid flows out from the center of the welding surface 7, the drive motor 53 starts operating, driving the drive gear 52 to rotate. The rotation of the gear 52, in turn, drives the entire furnace body 412 to rotate within the centrifugal rotor 51, thereby causing the aluminum profile to rotate synchronously around its own axis. After the welding wire flows out from the center of the welding surface 7, it melts into molten welding fluid upon heating. Under the action of centrifugal force, the molten welding fluid spreads from the center of the welding surface 7 to the surrounding areas, ensuring that the molten welding fluid is evenly distributed from the center to the edge of the welding surface 7.

[0050] After the molten solder is evenly distributed on the welding surface 7, the two aluminum profiles are connected to the power source by energizing the electrode sleeve 45. Due to the short circuit, the temperature at the contact point of the two aluminum profiles rises further until they melt, causing the welding surfaces 7 at both ends of the aluminum profiles to fuse perfectly with the molten solder, thus achieving welding.

[0051] During the aluminum profile welding process, molten aluminum and welding wire fluid overflow into the welding fluid overflow tanks 445 on both sides of the heating base 446. The design of the welding fluid tank 482 facilitates the timely removal of welding fluid overflowing from the welding surface 7 during the welding process, ensuring smooth flow of the welding fluid. The welding fluid on both sides of the welding fluid tank 482 eventually flows into the welding fluid overflow tank 445, and the overflowing welding fluid flows into the waste tank 42 via the welding fluid discharge tank 443, effectively reducing welding fluid residue on the surface of the aluminum profile during the welding process.

[0052] After welding of the welding surface 7 is completed, the drive motor 53 stops the rotation of the furnace body 412. Then, the clamping and adjusting mechanism 3 is used to push the welded aluminum profile to move left and right, so that the outer wall of the welding surface 7 is in full contact with the scraper 444, and the edge of the outer wall of the welding surface 7 is scraped to make the edge of the welding surface 7 smoother and more regular. Finally, the welding aluminum profile is transferred out of the furnace body 412 with the help of the feeding cart 22.

[0053] In summary, the welding equipment for aluminum profile processing in this embodiment of the invention heats the butt joint of the aluminum profiles to near melting temperature through the hot melt component in the welding mechanism. Then, the two aluminum profiles are connected to the power supply through the electric heating component. The contact area of ​​the two aluminum profiles is further heated and melted due to the short circuit, which enables the welding surfaces at both ends of the aluminum profiles to be fully fused and welded. In addition, the welding furnace component wraps and shapes the outer wall of the aluminum profile, making the outer side of the aluminum profile weld more regular and improving the welding quality.

[0054] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
