Description

Technical Field

[0001] This invention relates to the field of welding wire oven technology, and more specifically to a welding wire oven with temperature control function. Background Technology

[0002] Welding wire is a metal wire used as filler metal or simultaneously as a conductive electrode in welding. In gas welding and tungsten inert gas (TIG) welding, the welding wire is used as filler metal; in submerged arc welding, electroslag welding, and other gas metal arc welding, the welding wire is both filler metal and conductive electrode.

[0003] The surface of the welding wire is not coated with flux to prevent oxidation. However, in conjunction with the above, it should be noted that the surface of the welding wire needs to be kept relatively dry. Damp welding wire will cause problems such as slag inclusion and porosity during use. Therefore, damp welding wire needs to be placed in a special oven for drying.

[0004] For welding wire ovens, excessively high temperatures can cause secondary damage to the welding wire, while excessively low temperatures can prolong the drying time of the welding wire, making it difficult to meet normal usage requirements. In addition, during the drying process, the water vapor that evaporates from the welding wire fills the hot air, and the hot air filled with water vapor can also cause secondary damage to the welding wire. If the hot air filled with water vapor is extracted from the outside, the internal temperature of the oven will decrease.

[0005] In view of the above-mentioned technical problems, this application proposes a solution. Summary of the Invention

[0006] The purpose of this invention is to provide a special oven for welding wire with temperature control function. In the current ovens for drying welding wire, the temperature is difficult to control, which may lead to secondary damage or prolong the drying time.

[0007] The objective of this invention can be achieved through the following technical solution: a special oven for welding wire with temperature control function, comprising a box body, a cabinet door and a temperature sensor, wherein a first motor is provided at the center point of the top of the box body, and two slide frames are provided inside the box body. The two slide frames are arranged vertically, and a slide table is rotatably mounted at the center point of the slide frame. The slide table has multiple insertion holes. An electric heating plate is installed on the inner wall of the box body, and the temperature sensor is installed at the upper part of the inside of the box body. A gas collection hood is installed at the center point of the upper surface of the housing, and a return gas pipe is installed on the outside of the housing. One end of the return gas pipe is connected to the inside of the gas collection hood, and the other end of the return gas pipe is connected to the inside of the housing. The intersection point of the return gas pipe and the housing is located at the center point of the lower surface of the housing. The end of the transmission rod of the first motor passes through the gas collection hood and the housing respectively, and a turbine fan is installed on the outer circumferential wall of the gas collection hood on the transmission rod of the first motor. An air exchange structure is provided at the middle position of the return gas pipe. The air exchange structure includes a steering cover, a second motor, and a third motor. Two sets of vent pipes are installed on the upper side of the return gas pipe corresponding to the steering cover. The upper end of the vent pipe is connected to the inside of the return gas pipe.

[0008] Further configuration: a directional clamping plate is provided at the end of the first motor transmission rod, a directional clamping groove rod is installed at the center point of the upper surface of the slide frame, and the cabinet door is hinged to the outside of the box.

[0009] The design further includes: sliding grooves are provided on both sides of the inner wall of the box, and the two sides of the slide frame are slidably connected in the sliding grooves.

[0010] The configuration is further defined as follows: the two sets of vent pipes are symmetrically arranged along the return pipe, and the vent pipes are inclined downwards. A venting ball is installed at the intersection of the two sets of vent pipes. Two steering arc plates are provided on the inner wall of the return pipe. The two steering arc plates are mirror-symmetrically arranged along the return pipe and are arranged in a figure-eight shape.

[0011] The configuration is further defined as follows: the lower end of the steering arc plate is installed on the inner wall of the return air pipe, and the installation point of the steering arc plate and the return air pipe is lower than the connection point between the vent pipe and the return air pipe.

[0012] Further configuration: a triangular plate is installed at the output end of the second motor, a steering ball is installed at the output end of the third motor, the triangular plate is located inside the steering cover, the steering ball is located inside the air venting ball, an air baffle is installed at the three points of the triangular plate, and an air hole is opened on the triangular plate, the air baffle is matched with the steering arc plate.

[0014] The design further includes: air sieves are provided on both sides of the air vent on the steering ball, and an air groove is provided on the upper end of the steering ball; the interior of the steering ball is connected to the air vent pipe through the air groove.

[0015] The present invention has the following beneficial effects: This invention is not limited to a single temperature control module, but combines a method of replacing hot air. Specifically, it uses a first motor to drive the turbine fan to rotate, and the generated wind force exhausts the hot air inside the chamber. In the ventilation structure, different operating states are activated according to the temperature changes inside the chamber. One is to exhaust the hot air to the external environment, and the cold air in the external environment re-enters the chamber, which not only cools down the chamber, but also removes the humid and hot air, avoiding secondary damage to the welding wire caused by water vapor generated during the drying process. The other is to continuously circulate the hot air, which warms up the working environment inside the chamber. Furthermore, a sliding table structure has been added, with multiple insertion holes for placing welding wire. It should be noted that, combined with the insertion holes and the sliding table structure, the overall structure can also be used to dry various long and thin objects, such as welding rods and welding wires. The sliding table rotates synchronously with the operation of the first motor to promote airflow in the external environment of the welding wires and welding rods, thereby accelerating the drying efficiency.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 For welding wire ovens, excessively high temperatures can cause secondary damage to the welding wire, while excessively low temperatures will prolong the drying time, making it difficult to meet normal usage requirements. Furthermore, during the drying process, the water vapor released from the welding wire fills the hot air, which can also cause secondary damage. Removing this water vapor-filled hot air from the oven would lower the internal temperature. Therefore, the following technical solution is proposed: Reference Figures 1-7 This embodiment of a welding wire oven with temperature control function includes a cabinet body 1, a cabinet door 2, and a temperature sensor 27. A first motor 4 is set at the center point of the top of the cabinet body 1, and two slide racks 6 are set inside the cabinet body 1. The two slide racks 6 are set vertically, and a slide table 14 is rotatably installed at the center point of the slide rack 6. Multiple insertion holes 13 are opened on the slide table 14. An electric heating plate 12 is installed on the inner wall of the cabinet body 1, and the temperature sensor 27 is installed at the upper part of the inside of the cabinet body 1. A gas collection hood 5 is installed at the center point of the upper surface of the housing 1, and a return air pipe 3 is installed on the outside of the housing 1. One end of the return air pipe 3 is connected to the inside of the gas collection hood 5, and the other end of the return air pipe 3 is connected to the inside of the housing 1. The intersection point of the return air pipe 3 and the housing 1 is located at the center point of the lower surface of the housing 1. The end of the transmission rod of the first motor 4 passes through the gas collection hood 5 and the housing 1 respectively. A turbine fan blade 9 is installed on the outer circumferential wall of the gas collection hood 5. An air exchange structure is set at the middle position of the return air pipe 3. The air exchange structure includes a steering cover 15, a second motor 16, and a third motor 23. Two sets of vent pipes 17 are installed on the upper side of the return air pipe 3 corresponding to the steering cover 15. The upper end of the vent pipe 17 is connected to the inside of the return air pipe 3.

[0021] Two sets of vent pipes 17 are symmetrically arranged along the return pipe 3, and the vent pipes 17 are inclined downwards. A venting balloon 18 is installed at the intersection of the two sets of vent pipes 17. Two turning arc plates 19 are arranged on the inner wall of the return pipe 3. The two turning arc plates 19 are mirror symmetrically arranged along the return pipe 3, and the two turning arc plates 19 are arranged in a figure-eight shape.

[0022] The lower end of the steering arc plate 19 is installed on the inner wall of the return air pipe 3, and the installation point of the steering arc plate 19 and the return air pipe 3 is lower than the connection point of the vent pipe 17 and the return air pipe 3.

[0023] Operating principle: First, it should be noted that the drying temperature inside the chamber 1 is mainly detected by temperature sensor 27, and the maximum drying temperature is preset according to the drying requirements of the welding wire. Details will not be elaborated here. The main point is that when the first motor 4 is started, it first drives the turbine fan 9 to rotate, which then draws the hot air inside the chamber 1 into the return air pipe 3. In this state, the ventilation structure operates in the following two ways: When the drying temperature inside the chamber 1 is not higher than the maximum drying temperature, the second motor 16 is started, so that the air baffle 20 and the steering arc plate 19 are misaligned. Then most of the hot air can enter the steering cover 15, while some of the hot air enters the air vent 18 along the air vent pipe 17. At this time, the third motor is started, so that the air vent 21, the air vent 26 and the air vent 10 are not connected. Then the hot air can only be heated gradually along the return air pipe 3 into the inside of the chamber 1. When the drying temperature inside chamber 1 is higher than the maximum drying temperature, the second motor 16 is started, so that the air baffle 20 and the steering arc plate 19 are set opposite each other. Then, the hot air cannot enter the lower part of the return air pipe 3 through the steering cover 15, but only enters the air vent 18 along the vent pipe 17. At this time, the third motor 23 is started. First, the vent 26 is connected to the vent 10 to discharge the hot air. The water vapor in the hot air is discharged together. After the drying temperature inside chamber 1 gradually decreases, the air baffle 20 and the steering arc plate 19 are set off in a staggered manner again, and the hot air can flow along the return air pipe 3. Then, the air sieve 21 is connected to the vent 10 again. At this time, the cold air in the external environment can enter the steering ball 25 along the air sieve 21. Under the premise of "replenishing air", it can also cool down the air inside the return air pipe 3.

[0024] The temperature requirements mentioned above are specifically determined by the drying specifications of the welding wire, and will not be explained or limited here.

[0025] Example 2 This embodiment makes the following optimizations and improvements to the ventilation structure in Embodiment 1: A triangular plate 22 is installed at the output end of the second motor 16, and a steering ball 25 is installed at the output end of the third motor 23. The triangular plate 22 is located inside the steering cover 15, and the steering ball 25 is located inside the air venting ball 18. An air baffle 20 is installed at the three points of the triangular plate 22, and an air hole is opened on the triangular plate 22. The air baffle 20 is matched with the steering arc plate 19.

[0026] The directional ball 25 is rotatably connected inside the air venting ball 18. Multiple vents 10 are provided on the lower circumferential outer wall of the air venting ball 18. The directional ball 25 is provided with an air vent 26 on the lower side of the circumferential outer wall corresponding to the vents 10. Air sieves 21 are provided on both sides of the air vents 26 on the upper side of the directional ball 25. An air groove 24 is provided at the upper end of the directional ball 25. The interior of the directional ball 25 is connected to the air venting pipe 17 through the air groove 24.

[0027] Operating principle: Please refer to the following for details. Figure 6 and Figure 7 The baffle plate 20 and the steering arc plate 19 are offset, allowing hot air to flow normally along the air holes on the triangular plate. However, the structural characteristics of the steering arc plate 19 are further restricted, causing the baffle plate 20 and the steering arc plate 19 to be positioned opposite each other. Hot air can slowly "slide" into the vent pipe 17 along the upper curve of the steering arc plate 19, further restricting the tilt direction of the vent pipe 17. The purpose is to accelerate the "deposition" of hot air in the vent ball 18.

[0028] Example 3 This embodiment makes the following optimizations and improvements to the slide frame in Embodiment 1: The first motor 4 has a directional plate 8 at the end of the transmission rod, and a directional slot rod 7 is installed at the center point of the upper surface of the slide frame 14. The cabinet door 2 is hinged to the outside of the box 1. Slide grooves 11 are opened on both sides of the inner wall of the box 1, and the two sides of the slide frame 6 are slidably connected in the slide grooves 11.

[0029] Its advantages are: (See specific references) Figure 2 and Figure 3 The slide frame 14 is provided with multiple insertion holes 13 for placing welding wire. It should be noted that the structure of the slide frame 14 can also be used to dry various long strip-shaped objects, such as welding rods. Furthermore, during use, the slide frame 14 can be pulled out along the slide groove 11. When placed in its original position, the cabinet door 2 first presses against the slide frame 14, and the directional slot rod 7 cooperates with the directional plate 8 at the end of the transmission rod of the first motor 4. Thus, under the action of the first motor 4, the slide frame 14 is driven to rotate in the slide frame 6. The purpose is to accelerate the air flow in the external environment of the structure such as welding wire or welding rod, and accelerate the drying efficiency.

[0030] In summary: This system is not limited to a single temperature control mode, but combines hot air displacement with two methods: "exhausting" or "circulating" the hot air inside chamber 1. This effectively controls the drying temperature. Furthermore, while "exhausting" the hot air, it also simultaneously removes humid air, preventing secondary damage to the welding wire from water vapor generated during the drying process. Additionally, a sliding table 14 structure is added, with multiple insertion holes 13 for holding the welding wire. It should be noted that this system is not limited to the drying of welding wire; it can also be used to dry various long, thin objects, such as welding rods. Based on the rotational force provided by the circulating hot air, the sliding table 14 rotates synchronously to accelerate the flow of hot air in the external environment of the welding wire, thereby improving drying efficiency.
