A welding heat dissipation device with temperature monitoring

Abstract

This utility model discloses a welding heat dissipation device with temperature monitoring, relating to the field of welding equipment technology. It includes a support, a limiting rod installed on the outer wall of the support, a return spring installed on the outer wall of the limiting rod, a positioning frame installed on the outer wall of the limiting rod, limiting plates installed on both outer walls of the positioning frame, and temperature detectors installed on both outer walls of the positioning frame. This utility model, through the configuration of the support, limiting rod, return spring, positioning frame, and limiting plates, allows the support to be fixed to the processing table surface with bolts. Pulling the limiting plates causes the positioning frame to slide left and right along the limiting rod, facilitating the placement of welding parts without obstructing material loading. After loading, releasing the limiting plates allows the positioning frame to return to its center position via the return springs with consistent elasticity on both sides, thus positioning the heat dissipation area and ensuring it is always aligned with the welding point for heat dissipation. It is highly practical.

Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a welding heat dissipation device with temperature monitoring. Background Technology

[0002] Friction stir welding (FSW), a solid-state joining technology, utilizes the friction between a high-speed rotating stirring head and the workpiece to generate heat, bringing the workpiece to a thermoplastic state. Welding is achieved under the squeezing and stirring action of the stirring head. The process requires no filler material or shielding gas, effectively avoiding traditional fusion welding defects such as porosity and inclusions. It also results in minimal welding deformation and low residual stress. However, FSW generates a large amount of heat, primarily from the intense friction between the stirring head and the workpiece, as well as the plastic deformation of the material. If this heat cannot be effectively dissipated in time, it will reduce the joint's strength, toughness, and other mechanical properties, and cause welding deformation, affecting the dimensional accuracy and appearance quality of the weldment. Furthermore, precise temperature control plays a crucial role in welding quality; excessively high or low temperatures can lead to welding defects. To address these issues, a welding heat dissipation device with temperature monitoring is needed.

[0003] Existing welding heat dissipation devices have problems such as inability to accurately control the temperature at the welding point, inconvenience in replacing welded parts, and difficulty in locating the heat dissipation area. Therefore, there is an urgent need for a welding heat dissipation device with temperature monitoring. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a welding heat dissipation device with temperature monitoring to solve the problems of existing welding heat dissipation devices being unable to accurately control the temperature at the welding point, making it inconvenient to replace the welding parts, and locating the heat dissipation area.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding heat dissipation device with temperature monitoring, comprising a support, a limit rod installed on the outer wall of the support, a return spring installed on the outer wall of the limit rod, a positioning frame installed on the outer wall of the limit rod, limit plates installed on both outer walls of the positioning frame, temperature detectors installed on both outer walls of the positioning frame, a support frame installed at the bottom of the positioning frame, a dustproof plate installed on the inner wall of the support frame, a power motor installed on the outer wall of the dustproof plate, and fan blades installed on the outer wall of the power motor.

[0006] Preferably, the positioning frame forms a telescopic structure with the support via a return spring, and the positioning frame is movably connected to the limiting rod.

[0007] Preferably, the limiting rod is symmetrically arranged with the central axis of the positioning frame as the center, and the temperature detector is symmetrically arranged with the central axis of the positioning frame as the center.

[0008] Preferably, the support frame is welded to the positioning frame, and the fan blades are connected to the support frame via a power motor to form a rotating structure.

[0009] Preferably, the inner wall of the dustproof plate is provided with fine holes, and the dustproof plates are arranged in a rectangular array with the central axis of the positioning frame as the center.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the setting of a support, a limiting rod, a return spring, a positioning frame, and a limiting plate, fixes the support to the surface of the processing table with bolts. By pulling the limiting plate, the positioning frame slides left and right along the limiting rod, which facilitates the placement of welding parts and does not obstruct the loading. After the loading is completed, the limiting plate is released, and the positioning frame will be centered and reset by the return springs with consistent elasticity on both sides, thereby positioning the heat dissipation area so that it is always aligned with the welding point for heat dissipation. It is highly practical.

[0012] 2. This utility model uses a temperature detector, support frame, dustproof plate, power motor and fan blades. The temperature detectors on both sides monitor the weld in real time. When the temperature at the joint reaches the specified value, the temperature detector sends a signal to control the power motor to start and drive the fan blades to rotate at high speed to quickly dissipate heat from the joint, avoiding excessive temperature that could cause material grain coarsening and strength reduction. When the temperature drops to the specified value, the power motor is then controlled to shut off to avoid defects such as incomplete penetration caused by insufficient temperature.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] Please see Figures 1-4 A welding heat dissipation device with temperature monitoring includes a support 1, a limiting rod 2 installed on the outer wall of the support 1, a return spring 3 installed on the outer wall of the limiting rod 2, and a positioning frame 4 installed on the outer wall of the limiting rod 2. Limit plates 5 are installed on both sides of the outer wall of the positioning frame 4. The positioning frame 4 forms a telescopic structure with the support 1 via the return spring 3, and the positioning frame 4 is movably connected to the limiting rod 2. The limiting rod 2 is symmetrically arranged around the central axis of the positioning frame 4, and the temperature detector 6 is symmetrically arranged around the central axis of the positioning frame 4. After the support 1 is fixed to the surface of the processing table with bolts via the support 1, limiting rod 2, return spring 3, positioning frame 4, and limiting plates 5, the positioning frame 4 slides left and right along the limiting rod 2 by pulling the limiting plates 5, facilitating the placement of welding parts without obstructing material loading. After loading, the limiting plates 5 are released, and the positioning frame 4 will be centered and reset by the return springs 3 on both sides, thus positioning the heat dissipation area and ensuring it is always aligned with the welding point for heat dissipation. This device is highly practical.

[0021] Please see Figures 1-4 A welding heat dissipation device with temperature monitoring is disclosed. Temperature detectors 6 are installed on both outer walls of the positioning frame 4. A support frame 7 is installed at the bottom of the positioning frame 4. A dustproof plate 8 is installed on the inner wall of the support frame 7. A power motor 9 is installed on the outer wall of the dustproof plate 8. Fan blades 10 are installed on the outer wall of the power motor 9. The support frame 7 is welded to the positioning frame 4, and the fan blades 10 form a rotating structure with the support frame 7 via the power motor 9. The inner wall of the dustproof plate 8 is perforated, and the dustproof plates 8 are arranged in a rectangular array centered on the central axis of the positioning frame 4. The system is configured with a temperature detector 6, a support frame 7, a dustproof plate 8, a power motor 9, and a fan blade 10. The temperature detectors 6 on both sides monitor the weld joint in real time. When the temperature at the joint reaches a specified value, the temperature detector 6 sends a signal to control the power motor 9 to start and drive the fan blade 10 to rotate at high speed to quickly dissipate heat from the joint. This prevents the material grains from coarsening and the strength from decreasing due to excessive temperature. When the temperature drops to a specified value, the power motor 9 is turned off to prevent defects such as incomplete penetration caused by insufficient temperature.

[0022] Working principle: In use, first, the support 1 is fixed to the surface of the processing table with bolts. Then, by pulling the limiting plate 5, the positioning frame 4 slides left and right along the limiting rod 2, which facilitates the placement of the welding parts and does not obstruct the loading. After loading, the limiting plate 5 is released, and the positioning frame 4 will be centered and reset by the return springs 3 on both sides with consistent elasticity, thereby positioning the heat dissipation area so that it is always aligned with the welding point for heat dissipation. It is highly practical. During the welding process, the temperature detectors 6 on both sides monitor the welding point in real time. When the temperature at the joint reaches the specified value, the temperature detectors 6 send a signal to control the power motor 9 to start and drive the fan blades 10 to rotate at high speed to quickly dissipate heat at the joint, avoiding excessive temperature that may cause material grain coarsening and strength reduction. When the temperature drops to the specified value, the power motor 9 is turned off to avoid defects such as incomplete penetration caused by insufficient temperature. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.
