Description

Technical Field

[0001] This utility model relates to the field of VC copper pipe welding technology, specifically to a VC copper pipe welding device. Background Technology

[0002] Currently, the welding of VC sheets to copper tubes mainly relies on brazing. This requires manual alignment of the workpieces, insertion into a high-powered heater for heating, manual feeding of brazing filler metal to fill the gaps, and completion of the welding after cooling. This technology has significant drawbacks, as follows: First, the production efficiency is extremely low, making it difficult to adapt to mass production. The existing process adopts a single-set workpiece, single-process mode. Each set of workpieces needs to go through heating, brazing, and cooling processes. The process switching and waiting time are long, and the processing volume per unit time is far from meeting the large-scale demand for VC heat dissipation components in fields such as electronic equipment and new energy vehicles, thus restricting the industrialization process. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a VC copper pipe welding device, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a VC copper pipe welding device, comprising two mounting brackets; High-frequency heaters are provided on the upper surface of both mounting brackets, and the two mounting brackets are provided with a transmission structure for transmitting the workpiece body, so that the transmitted workpiece body slowly passes between the two high-frequency heaters. The transmission structure includes a rotating shaft rotatably connected between the two mounting brackets and spaced apart to the left and right. A sprocket is fixedly sleeved on the outer side of each of the two rotating shafts. The outer side of the two sprockets on the same horizontal line is connected to the same chain. Multiple horizontal plates are provided on the outer side of one of the chains, and the other end of the horizontal plate is connected to another chain. A motor with its output end connected to one of the rotating shafts is mounted on the front mounting bracket. The horizontal plate is also provided with a fixing structure for fixing the workpiece.

[0005] Furthermore, the plurality of the cross plates are arranged at equal intervals along the length direction of the chain.

[0006] Furthermore, the fixing structure includes a column vertically installed on the horizontal plate, a base plate installed on the top of the column, and elastic members provided on both the left and right sides of the base plate. Both elastic members are inclined toward each other and fit together. On the upper surface of the base plate, and between the two elastic members, two limiting plates are also provided.

[0007] Furthermore, the column is made of stainless steel, and the base plate and the elastic element are both made of spring steel with a thickness of no more than one millimeter.

[0008] Furthermore, the top ends of both elastic components are bent in the opposite direction.

[0009] Furthermore, a gap is maintained between the two limiting plates.

[0010] Furthermore, it also includes the VC board body and the copper tube body; The VC plate body is inserted between the two elastic members, and its bottom end extends to the gap between the two limiting plates. An opening adapted to the length of the VC plate body in the X-axis direction is provided at the bottom end of the copper tube body. A groove is provided on the top of the VC plate body and on the side in contact with the copper tube body for the copper tube body to be partially embedded. A brazing ring is fitted on the outer side of the copper tube body, and the brazing ring is also in contact with the top of the VC plate body.

[0011] Furthermore, a heat dissipation structure is also provided on the mounting bracket; The heat dissipation structure includes a frame spanning the two mounting brackets, with cooling fans installed on the top and left and right sides of the frame.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This VC copper pipe welding equipment uses a chain drive in its transmission structure to allow multiple workpieces to move cyclically with the horizontal plate, simultaneously completing the feeding, heating, welding, and unloading processes. This replaces the traditional single-workpiece, single-processing mode, significantly increasing the processing capacity per unit time.

[0013] 2. This VC copper pipe welding equipment has a high degree of automation. Only the staff needs to complete the pre-loading and unloading of the workpiece. There is no need for manual handling of the workpiece for heating or manual feeding of brazing filler metal, which greatly reduces the number of manual operation steps. The automated operation of the transmission and heat dissipation structure reduces the time that the staff spends in high-temperature areas, reduces labor intensity and safety risks, and at the same time reduces the reliance on skilled workers and lowers labor costs.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This embodiment of a VC copper tube welding equipment is used to realize the automated and continuous brazing process between the VC board body 4 and the copper tube body 5, solving the problem of low efficiency of traditional manual welding. It includes two mounting brackets 1, a high-frequency heater 2, a transmission structure 3, a VC board body 4, a copper tube body 5, a brazing ring 6, and a heat dissipation structure 7. Specifically, the mounting frame 1 provides a supporting foundation for the entire equipment. Two mounting frames 1 are set in parallel and spaced apart. High-frequency heaters 2 are fixedly installed on the upper surface of each frame. The two high-frequency heaters 2 are set opposite to each other to form a welding heating area. When the workpiece to be welded passes between the two high-frequency heaters 2, it can be uniformly heated to the temperature required for brazing.

[0018] In detail, the transmission structure 3 is installed between the two mounting brackets 1 to drive the workpiece through the heating zone at a uniform speed, enabling continuous processing. It includes two rotating shafts 301, sprockets 302, chains 303, cross plates 304, motors 305, and a fixing structure. The two rotating shafts 301 are rotatably connected between two mounting brackets 1 at left and right intervals through bearings. Two sprockets 302 are fixedly sleeved on the outer side of each rotating shaft 301. The two sprockets 302 on the same horizontal line are connected to the same chain 303 on their outer sides. Multiple cross plates 304 are equidistantly arranged along the length of the chain 303. The two ends of each cross plate 304 are fixedly connected to the outer sides of two chains 303 respectively, and move synchronously with the chains 303.

[0019] In actual setup, the motor 305 is fixed on the outside of the front mounting bracket 1, and its output end is connected to one of the rotating shafts 301 via a coupling to provide power to the transmission structure 3. When the motor 305 is running, it drives the rotating shaft 301 to rotate, which in turn drives the sprocket 302 and the chain 303 to rotate, so as to achieve uniform movement of the horizontal plate 304.

[0020] More specifically, the fixing structure is set on the horizontal plate 304 to securely clamp the VC board body, including the column 306, the base plate 307, the elastic element 308 and the limiting plate 309.

[0021] The column 306 is vertically fixed to the upper surface of the horizontal plate 304 and is made of stainless steel, providing good support strength. The base plate 307 is fixed to the top of the column 306 and, along with the elastic component 308, is made of spring steel with a thickness of no more than one millimeter, combining toughness and heat resistance. There are two elastic components 308, which are fixed to the left and right sides of the base plate 307 respectively. They are inclined in opposite directions and their tops are close to each other. The tops are also bent in the opposite direction to form a guide structure to facilitate the placement of the workpiece. There are two limiting plates 309, which are fixed to the upper surface of the base plate 307 and located between the two elastic components 308. A gap is maintained between the two limiting plates 309 for lateral limiting of the VC plate body 4.

[0022] In addition, the VC plate body 4 and the copper tube body 5 are the workpieces to be welded. The VC plate body 4 is inserted between the two elastic members 308, and its bottom end extends into the gap between the two limiting plates 309. The elastic clamping force of the elastic members 308 can firmly fix the VC plate body 4, while the limiting plates 309 prevent the VC plate body 4 from shifting left and right. The bottom end of the copper tube body 5 has an opening that matches the length of the VC plate body 4 in the X-axis direction, and the top of the VC plate body 4 has a groove on the side that contacts the copper tube body 5. The copper tube body 5 is inserted into the VC plate body 4 through the opening and the groove to achieve docking. The brazing ring 6 is sleeved on the outside of the copper tube body 5 and is also attached to the top of the VC plate body 4. When heated, the brazing ring 6 melts and can fill the gap between the VC plate body 4 and the copper tube body 5 to form a strong weld.

[0023] Preferably, the heat dissipation structure 7 is mounted across the two mounting brackets 1, located behind the high-frequency heater 2, for rapidly cooling the welded workpiece. It includes a frame 701 and cooling fans 702. The frame 701 is a gate-shaped structure, fixed to the top of the two mounting brackets 1. Cooling fans 702 are fixedly installed on the top and left and right sides of the frame 701. Multiple cooling fans 702 blowing air simultaneously can accelerate the airflow around the workpiece, quickly remove heat, and shorten the cooling time.

[0024] The working principle of the above embodiments is as follows: (1) Insert the VC plate body 4 into the bend at the top of the two elastic members 308 until its bottom end extends into the gap between the two limiting plates 309. The elastic members 308 clamp the VC plate body 4 under the elastic action. Then, put the brazing ring 6 on the outside of the copper tube body 5, and then align the opening of the copper tube body 5 with the top of the VC plate body 4, so that the copper tube body 5 is partially embedded in the groove of the VC plate body 4, and the brazing ring 6 is attached to the top of the VC plate body 4, thus completing the pre-assembly of the workpiece.

[0025] (2) Subsequently, the motor 305 drives the shaft 301 to rotate, the sprocket 302 drives the chain 303 to run, and the horizontal plate 304 moves at a constant speed towards the high-frequency heater 2 along with the chain 303. When the horizontal plate 304 with the pre-loaded workpiece enters the heating area between the two high-frequency heaters 2, the high-frequency heater 2 starts and releases heat to heat the workpiece and the brazing ring 6 to the melting temperature. After the brazing ring 6 melts, it fills the gap between the VC plate body 4 and the copper tube body 5. The workpiece continues to move with the horizontal plate 304 and enters the coverage area of ​​the heat dissipation structure 7 after leaving the heating area. The heat dissipation fan 702 on the frame 701 blows air to accelerate the cooling of the workpiece and solidify the brazing ring 6, thus completing the welding of the VC plate body 4 and the copper tube body 5. Finally, the workpiece moves with the chain 303 to the end of the transmission structure 3. The worker removes the welded component from the fixed structure. The empty fixed structure is circulated back to the initial position with the chain 303, and the next round of workpiece pre-loading can be carried out to realize continuous production.
