Description
Technical Field
[0001] The utility model relates to the technical field of welding, in particular to a welding heating device for thin-walled complex workpieces. Background Art
[0002] Existing technology uses electric heating, which involves installing a heater with a similar or similar appearance to the workpiece on its outer wall. When powered on, the heater begins to work, transferring heat to the workpiece. This heating method has the disadvantages of fixed relative positions between the workpiece and the heater, poor temperature uniformity, and limited flexibility.
[0003] Due to the thin wall and complex shape of the workpiece, traditional welding heating methods often cannot achieve the ideal heating effect and welding quality. Therefore, a special heating device is needed to solve this problem. Utility Model Content
[0004] In order to overcome the problems existing in the prior art, the purpose of the utility model is to provide a welding heating device for thin-walled complex workpieces.
[0005] The technical solution adopted by the utility model to solve the technical problem is: a thin-walled complex workpiece welding heating device, comprising:
[0006] A first frame, a first fixing portion, a first heating portion, and a second frame, a second fixing portion, and a second heating portion;
[0007] The first heating portion is fixedly connected to the first frame via the first fixing portion, and a side opening of the first heating portion faces away from the first frame;
[0008] The second heating portion is fixedly connected to the second frame via the second fixing portion, and a side opening of the second heating portion faces away from the second frame;
[0009] The side opening of the first heating part and the side opening of the second heating part are arranged opposite to each other, and the first heating part and the second heating part are buckled together to form a heating cavity for welding thin-walled pipes.
[0010] Main Working Principle: The device consists of two main parts: the first component, which includes a first frame, a first fixing part, and a first heating part; and the second component, which includes a second frame, a second fixing part, and a second heating part. The first heating part is securely mounted on the first frame via the first fixing part, with its side opening facing away from the first frame. Similarly, the second heating part is securely connected to the second frame via the second fixing part, with its side opening also facing away from the second frame.
[0011] When welding thin-walled pipes, the pipe to be welded is first placed in the apparatus. The first and second frames are then precisely adjusted relative to each other, ensuring that the side openings of the first and second heating units are precisely aligned and interlocked. This interlocking of the side openings of the first and second heating units creates a closed heating chamber that tightly encloses the area of the thin-walled pipe to be welded. The first and second heating units are then activated, uniformly heating the thin-walled pipe within the chamber.
[0012] Because the first and second heating elements are in close contact with the pipe, they ensure efficient and even heat transfer to the thin-walled pipe, thereby improving welding quality and efficiency. After reaching the appropriate welding temperature, subsequent welding operations such as filling solder and applying pressure can be carried out to complete the welding of the thin-walled pipe.
[0013] By interlocking two heating elements to form a heating chamber, the device can efficiently and evenly heat thin-walled pipes, avoiding welding defects caused by uneven heat distribution in traditional welding. Furthermore, because the heating chamber is enclosed, it can also reduce heat loss to a certain extent, improving energy efficiency.
[0014] In summary, the thin-walled complex workpiece welding heating device can effectively improve the quality and efficiency of thin-walled pipe welding through its unique structural design and working principle.

The heating chamber can also reduce the impact of the external environment on the welding process, such as air flow and temperature fluctuations, to a certain extent, thereby further improving welding quality. At the same time, because the heating chamber is closed, heat loss is reduced, which can also save energy to a certain extent and reduce welding costs.

[0039] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of this application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention. The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0041] Example 1
[0042] This embodiment discloses a thin-walled complex workpiece welding heating device, such as Figure 1-Figure 2 As shown, the apparatus comprises a first frame 1, a first fixing portion 2, a first heating portion 3, a second frame, a second fixing portion 5, and a second heating portion 6. The first heating portion 3 is securely connected to the first frame 1 via the first fixing portion 2, with its side opening facing away from the first frame 1 to form a closed cavity with the second heating portion 6. The second heating portion 6 is similarly connected to the second frame.
[0043] When it is necessary to weld a thin-walled pipe 7, first adjust the relative position of the first frame 1 and the second frame so that the side opening of the first heating part 3 and the side opening of the second heating part 6 can be precisely aligned. Subsequently, the first heating part 3 and the second heating part 6 are fastened to each other by screws to form a heating chamber. This heating chamber tightly wraps the part of the thin-walled pipe 7 that needs to be welded. After starting the heating device, the first heating part 3 and the second heating part 6 start working, generating heat and transferring it evenly to the thin-walled pipe 7 through the inner wall of the heating chamber. Since the heating chamber is closed, the heat can heat the pipe efficiently and evenly, thereby achieving the ideal welding temperature. This design ensures the uniformity and efficiency of heating, avoids welding defects caused by uneven heat distribution in traditional welding, and the position of the entire device can be adjusted according to the position of the thin-walled pipe 7.
[0044] In some optional embodiments, a first docking plate 20 and a second docking plate 50 are respectively provided on both sides of the first heating portion 3 and the second heating portion 6. The first docking plate 20 and the second docking plate 50 are detachably connected by screws, which facilitates the rapid disassembly and replacement of the heating portion.
[0045] When the thin-walled pipe 7 needs to be maintained or replaced, the first butt joint plate 20 and the second butt joint plate 50 can be easily separated by loosening the screws, thereby separating the first heating part 3 and the second heating part 6, and removing the thin-walled pipe 7 from the first heating part 3 and the second heating part 6. Conversely, when the thin-walled pipe 7 needs to be fixed and heated, the installation can be completed by aligning the butt joint plates and tightening the screws.
[0046] This detachable connection design improves the maintenance convenience and flexibility of the device, reduces the use cost, and allows the user to quickly replace docking plates and heating parts of different specifications or types according to actual needs.
[0047] In some optional embodiments, a first connecting plate 21 and a second connecting plate 51 are further provided on either side of the first heating unit 3 and the second heating unit 6, respectively. The first connecting plate 21 and the second connecting plate 51 are fixed to the frame by welding, bolting, or other fastening methods, thereby enhancing the stability between the heating unit and the frame. During the welding process, even when subjected to large external forces or vibrations, the heating unit can remain stable and motionless, ensuring the accuracy and safety of the welding. This stable connection design improves the overall stability of the device, ensures the accuracy and safety of the welding process, and avoids welding failures or safety accidents caused by loose heating units.
[0048] In some optional embodiments, the first heating unit 3 includes a first welding portion 30 and a first heating tube 31, and the second heating unit 6 similarly includes a second welding portion 60 and a second heating tube 61. The first welding portion 30 and the first heating tube 31, as well as the second welding portion 60 and the second heating tube 61, are tightly fitted together, and both ends of the heating tubes are connected to the fixing portion by means such as welding or clamping.
[0049] When the heating device is activated, the first and second heating tubes 31, 61 begin to operate and generate heat. This heat is rapidly transferred to the thin-walled pipe 7 via the first and second welding portions 30, 60, bringing it to the required welding temperature. Because the welding portion closely fits the heating tube, heat transfer is efficient and uniform. This design ensures efficient heat transfer and uniform distribution, improving heating efficiency and welding quality. Furthermore, the close fit of the welding portion and the heating tube also enhances the structural strength and service life of the heating unit.
[0050] In some optional embodiments, at least three sets of first heating units 3 and second heating units 6 are respectively provided on the first frame 1 and the second frame according to the size and shape requirements of the thin-walled pipe 7. These first heating units 3 and second heating units 6 are arranged around the thin-walled pipe 7 and work in conjunction with each other.
[0051] During the welding process, multiple groups of heating parts are started at the same time and generate heat to fully heat the thin-walled pipe 7. This arrangement can ensure that the pipe is evenly and fully heated during the welding process to achieve an ideal welding effect.
[0052] In some optional embodiments, first arc grooves 22 and second arc grooves 52 are respectively provided at the connection points between the first fixing portion 2 and the second fixing portion 5 and the ends of the heating portion. The ends of the first heating portion 3 and the second heating portion 6 are connected to the fixing portion via the first arc grooves 22 and the second arc grooves 52, thereby ensuring that the first heating portion 3 and the second heating portion 6 can be positioned along the first arc grooves 22 and the second arc grooves 52. The design of the first arc grooves 22 and the second arc grooves 52 enables the heating portions to maintain a certain degree of mobility and adaptability during the connection process, thereby enhancing the stability of the connection.
[0053] In some optional embodiments, first and second rollers 10 and 40 are provided at the bottom of the first and second frames, respectively. The design of the first and second rollers 10 and 40 allows the device to be easily moved and positioned on the ground or other flat surfaces. Moving the device is easy with a push or pull; positioning the device can be fixed by locking the rollers. This improves the device's flexibility and ease of use, reducing operational difficulty. The presence of the rollers also enhances its mobility and portability, allowing it to be easily used in various workplaces and environments.
[0054] In summary, the thin-walled, complex workpiece welding heating device of the present invention achieves efficient and uniform heating of thin-walled pipes (7), improving welding quality and efficiency through the specific implementation methods and detailed operating principles of each claim. Furthermore, the device's flexible structural design, ease of operation and maintenance, and broad application prospects and promotional value are evident. The foregoing description is merely a preferred embodiment of the present invention and does not constitute any formal limitation upon the present invention. Therefore, any modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical content of the present invention and are based on the technical essence of the present invention remain within the scope of the present invention.
