Description

Technical Field

[0001] This utility model relates to the field of welding, and in particular to a moisture-proof storage device for welding electrodes. Background Technology

[0002] Welding electrodes consist of two parts: the core and the coating. The coating is applied evenly and press-pressed onto the metal core, and welding is achieved by melting the metal parts with the high temperature of an electric arc.

[0003] Before welding, welding electrodes need to be heated. The main purposes of heating are as follows: 1. Preventing the electrodes from getting damp: Heating removes moisture from the electrodes, ensuring better weld quality and strength. 2. Preheating the core material to enhance weldability: Preheating the core material enhances the weldability of the electrodes and improves the welding process. 3. Reducing welding stress: Preheating reduces the temperature difference between the workpieces in the welding area, lowers welding stress, and reduces the welding strain rate, which helps avoid welding cracks. 4. Reducing the constraint of the welded structure: Preheating reduces the constraint of the welded structure, especially corner joints. As the preheating temperature increases, the crack incidence decreases. 5. Slowing down the cooling rate after welding: Preheating slows down the cooling rate after welding, which facilitates the escape of diffusing hydrogen from the weld metal, preventing hydrogen-induced cracks. It also reduces the hardening degree of the weld and heat-affected zone, improving the crack resistance of the weld joint.

[0004] As for the heating temperature of the welding rod, there are different requirements depending on the type and material of the welding rod: the drying temperature of acidic welding rod is 150-200℃, and the holding temperature is 1-2 hours; the drying temperature of basic welding rod is 350-400℃, and the holding temperature is 1-2 hours.

[0005] In high-altitude welding operations, the low ambient temperature and potentially high humidity can cause the welding rods to become cold or damp, severely affecting the welding quality. Furthermore, traditional insulated boxes are bulky and inconvenient to use for power generation, material retrieval, and carrying at high altitudes, making them unsuitable for high-altitude welding operations.

[0040] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0041] See Figures 1-13 This utility model provides a moisture-proof storage device for welding rods, including a box 11, a cover 12, a discharge mechanism, a detection device, and a heating device.

[0042] The box body 11 has a rectangular parallelepiped structure. Rope buckles 111 are provided on both sides of the box body 11 for attaching shoulder straps for easy carrying, making it particularly suitable for high-altitude welding operations. A material storage cavity 20 is formed inside the box body 11, with an open top for holding welding rods. A cover 12 is hinged to the open top of the box body 11 to close the material storage cavity 20, forming a sealed chamber. A handle 121 is provided on the top of the cover 12 for carrying. In this embodiment, a recess is provided on the top surface of the cover 12, and the handle 121 is rotatably installed in this recess. When carrying is complete, the handle... 121 rotates and is hidden within the concave cavity, with no outward protrusion at its upper end, facilitating stacking and featuring a compact structure and aesthetically pleasing appearance. A quick-locking mechanism is provided between the cover 12 and the box body for rapid connection between them. This quick-locking mechanism consists of two parts located at the front end of the box body 11, including a locking hook 131 on the cover 12 and a locking buckle 132 on the box body 11. Both the box body and the cover are equipped with insulation layers, providing overall insulation functionality. Simultaneously, a sealing ring is provided between the open end of the box body and the cover to achieve a seal, improve airtightness, prevent heat loss, and enhance insulation performance.

[0043] The discharge mechanism is located below the front end of the housing 11 and is used for discharging welding rods. Specifically, the bottom surface of the material storage cavity 20 is inclined, and a discharge port 200 is provided at the lowest point. In this embodiment, a first bottom plate 21 and a second bottom plate 22 are inclinedly arranged at the bottom of the material storage cavity 20. The first bottom plate 21 and the second bottom plate 22 are arranged in a V-shape, and there is a gap at their ends to form the discharge port 200, which can allow a welding rod to pass through. Specifically, the second bottom plate 22 includes a second bottom plate with the front end inclined downward. The main body 221 and the second base plate 221 have their front ends bent downwards to form a first guide section 222. The end of the second guide section 222 is bent forwards to form a forward-leaning second guide section 223, with an angle of 10°-15° between it and the horizontal plane. The second guide section 223 faces the inlet end of the discharge mechanism. The discharge mechanism includes a support plate 3, which is rotatably hinged to the lower end of the discharge port 200. Its axis of rotation is parallel to the length direction of the welding rod in the material placement cavity. In this application, the rear end of the material support plate 3, i.e., the hinge shaft, is close to the second guide section 223 and located at the lower end of the second guide section 223, allowing the discharged welding rod to enter the material support plate 3; the front end of the material support plate 3 extends outside the housing 11 as the discharge end, and the front end of the material support plate 3 is bent upward to form a front baffle plate 33 for limiting the rolling of the welding rod; the front face of the housing 11 has a discharge port 110, which is a horizontally arranged strip-shaped hole, and the discharge port 110 can accommodate the material support plate 3. The material plate 3 passes through and provides space for its vertical rotation. The upper and lower ends of the discharge port 110 can contact the material plate 3, thereby limiting the rotation of the material plate 3. At the same time, an elastic component is provided inside the box 11. This elastic component gives the material plate 3 an upward movement tendency, thereby closing the discharge path of the material plate 3. This elastic component can be a torsion spring or a compression spring. When it is a torsion spring, it is set between the rotating shaft of the material plate 3 and the box. When a compression spring is used, it is set at the lower end of the material plate.

[0044] In this application, a flexible windproof cloth 8 is provided between the bottom surface of the material support plate and the lower end of the discharge port. This windproof cloth can prevent external cold air from entering the box through the discharge port and causing heat loss, thereby improving the heat preservation effect. The windproof cloth will not affect the rotation of the material support plate. At the same time, a flexible heat insulation layer is provided on the windproof cloth to further improve the heat preservation effect. Meanwhile, heat insulation layers (heat preservation layers) are provided at the bottom of the material placement cavity and the bottom surface of the material support plate 3. Specifically, they are provided on the bottom surfaces of the first bottom plate 21 and the second bottom plate 22. At the same time, a heat insulation layer is also provided on the bottom surface of the material support plate 3 to reduce heat loss. In order to further reduce the heat dissipation of the material support plate, in this embodiment, the material support plate 3 can be made of high-strength engineering plastic to eliminate heat loss.

[0045] When the material support plate 3 is in the upper limit position, it contacts the top of the discharge port 110. At this time, the material support plate 3 is in a basically horizontal state, and the welding rod at the front end of the material support plate 3 contacts the inner wall of the material placement cavity and cannot be discharged outward. When the material support plate 3 is pressed down and rotated to the lower limit position, its lower end contacts the lower end of the discharge port, achieving a limit. At this time, a gap is formed between the upper end of the material support plate 3 and the top of the discharge port. This gap can allow a welding rod to pass through. After the welding rod passes through the discharge port, it rolls down to the end of the material support plate 3. The front baffle plate 33 blocks the welding rod, and only one welding rod can be accommodated outside. That is, the width of the material support plate 3 located outside is slightly larger than the diameter of the welding rod. Therefore, only one welding rod can pass through and enter the front end of the material support plate 3, preventing excessive discharge and affecting the welding rod temperature. In order to prevent the welding rod from axially slipping, especially when placed at an angle, in this embodiment, side baffles 331 are provided on both sides of the front end of the material support plate 3 to prevent the welding rod from axially slipping and improve the safety and reliability of use.

[0046] To reduce noise from impacts and improve internal sealing, this application provides a rubber layer between the contact surfaces of the material support plate 3 and the discharge port 110. This rubber layer is positioned along the edge of the discharge port 110, serving as a buffer and seal. Specifically, a first rubber layer is provided between the upper surface of the material support plate 3 and the upper contact surface of the discharge port 110, primarily for sealing and buffering. A second rubber layer is provided between the lower surface of the material support plate 3 and the lower contact surface of the discharge port 110, primarily for buffering.

[0047] To ensure the reliability and stability of electrode feeding and prevent accumulation and jamming, this application provides a top plate 32 at the upper end of the support plate 3. The top plate 32 is parallel to the support plate 3 and rigidly fixed to the upper end of the support plate 3. During manufacturing, both ends of the top plate 32 are bent downwards at 90 degrees to form a connecting part, which is fixedly connected to the support plate 3. A feeding channel is formed between the support plate 3 and the top plate 32. This feeding channel can accommodate a single electrode to pass through. The inlet end of the feeding channel is connected to the feeding end of the second guide part 223, which can realize the orderly feeding of the electrode, avoid accumulation and jamming, and improve the stability and reliability of feeding.

[0048] The detection device is located at the lower end of the cover 12. It includes a temperature sensor 51 and a humidity sensor 52, which are used to detect the temperature and humidity inside the material chamber 20, respectively. At the same time, a buzzer for alarm is also installed on the box. When the internal temperature is detected to be lower than the specified value or the humidity is detected to be higher than the specified value, the buzzer alarm will be sounded to remind the operator to avoid continuing to use the low temperature or damp welding rod inside, which would affect the welding quality.

[0049] A heating device is installed on at least one side wall of the material placement chamber 20 to heat the chamber and continuously provide heat to compensate for the heat loss during use, thereby improving the heat preservation effect, ensuring the temperature of the welding rod inside, effectively protecting the performance of the welding rod before use, and reducing the welding defect rate caused by environmental factors. At the same time, an exhaust channel is provided at the upper end of the side wall of the material placement chamber 20. When it is accidentally damp, the water vapor evaporated after heating can be discharged to achieve internal drying. A valve plate 7 is provided on the exhaust channel. The valve plate is used to control the connection or blockage between the exhaust channel and the outside. It is used to open and exhaust when heated due to moisture. Under normal working conditions, it is in the closed state, forming a sealed cavity inside to prevent heat loss and prevent external dust, water vapor, etc. from entering.

[0050] In this application, a cavity is formed inside the housing 11. A vertical partition is provided inside the cavity, parallel to the length direction of the housing 1, i.e., parallel to the length direction of the internal welding rod. The vertical partition is located at the rear end of the cavity, dividing the cavity into a front cavity 10a and a rear cavity. The width of the front cavity is much larger than the width of the rear cavity, and the material placement cavity 20 is located in the front cavity 10a. A horizontal partition is provided in the rear cavity. In this application, the horizontal partition is located at the upper end of the rear cavity, dividing the rear cavity into an upper cavity 10c and a lower cavity 10b. The height of the lower cavity 10b is much larger than the height of the upper cavity 10c. A heating device is located in the lower cavity 10b, which is attached to the rear end side wall of the material placement cavity 20, thereby heating the welding rod in the material placement cavity 20. An exhaust port 201 is provided above the rear end of the front cavity 10a, and the exhaust port 201 is connected to the upper cavity 10c. The upper cavity 10c has a first exhaust hole 1030 on its side wall, forming an exhaust channel. In this embodiment, the lower cavity 10b has an open rear end, forming a rectangular mounting port 1020. The heating device is an electric heater 62, which is a rectangular sheet structure that fits against the rear end face of the front cavity 10a.

A heat insulation layer 63 is provided on the inner side of the cover plate 64 for heat insulation, preventing heat leakage and reducing energy loss. In this embodiment, the heat insulation layer 63 is heat insulation cotton, which fits against the inner wall of the cover plate 64. In order to improve the heat conduction efficiency, a heat-conducting layer 61 is provided between the contact surface of the electric heater 62 and the side wall of the material placement cavity 20. The heat-conducting layer is an aluminum film or a copper film.

[0051] In this application, the electric heater can be driven by a low voltage, similar to the electric heating structure on electrically heated clothing, and can be used with a 5V power supply; the power supply can be built-in or external.

[0052] Meanwhile, an insulation layer is also provided inside the inner wall of the box, forming an insulated cavity inside the box to prevent heat loss and achieve insulation.

[0053] The valve plate 7 is a rectangular plate structure that fits snugly against the inner wall of the upper cavity 10c and can slide up and down. Specifically, there are retainers 1033 on both sides of the inner wall of the upper cavity 10c, and slots are formed on the opposite surfaces of the two retainers. The valve plate 7 is engaged between the two slots to form a sliding motion, and its rear end face fits against the inner wall of the upper cavity. To improve airtightness, a rubber layer is provided on the rear end face of the valve plate, which is in close contact with the inner wall of the upper cavity to improve sealing and generate a certain amount of damping for easy operation and adjustment. The first exhaust hole 1030 is a horizontally arranged strip hole, which is set between the two retainers. The outlet end of the first exhaust hole 1030 is inclined downward to provide rain protection. There are multiple first exhaust holes 1030, arranged sequentially from top to bottom. At the same time, a second exhaust hole 70 corresponding to the first exhaust hole 1030 is formed on the valve plate 7. 1. When the valve plate 7 is in the upper limit position, the second exhaust port 701 is connected to the first exhaust port 1030, and exhaust can be achieved at this time; when the valve plate 7 is in the lower limit position, the second exhaust port 701 is misaligned with the first exhaust port 1030, and the exhaust port 201 is not connected to the outside, and a sealed cavity is formed inside, which has the function of dustproof and rainproof; a toggle block 71 is provided on the valve plate 7, which is used to move the valve plate up and down, thereby realizing the connection or blockage between the second exhaust port 701 and the first exhaust port 1030, that is, to open or close the exhaust channel; in this application, the toggle block 71 is located at the center of the rear end of the valve plate 7, which is a rearwardly extending protrusion structure. At the same time, a toggle block opening 1031 is provided on the rear end face of the upper cavity 10c, which allows the toggle block 71 to pass through and allows the toggle block to move up and down.

Magnetic field generation and control: The internal magnet has N and S poles along its diameter. By rotating the internal magnet, the distribution and intensity of the magnetic field can be controlled. When the magnet rotates to the middle position, the magnetic lines of force form a closed circuit between the two magnetic conductors, thus cutting off the magnetic force of the magnetic base. This allows the enclosure to be fixed to the high-altitude support plate, and the magnetic force can be switched on and off via the switch. It is convenient to use, highly safe, and requires no electric drive.
