Description

Technical Field

[0001] This utility model relates to the field of electric welding machine technology, and more specifically, to an energy-saving electric welding machine. Background Technology

[0002] Currently, industrial welding machines generally adopt forced air cooling systems to ensure the stable operation of power devices. A common design is to install a fixed fan on the back panel of the welding machine housing. The fan motor drives the fan blades to rotate, continuously expelling the hot air accumulated inside the housing to the external environment. To meet the high-temperature heat dissipation requirements of high-power components, a common layout is to install multiple axial fans in parallel at the ventilation openings on the back panel of the housing. By increasing the number of fans and the coverage area, this design can increase the total ventilation volume per unit time, thereby ensuring the thermal stability of the welding machine under continuous welding conditions.

[0003] However, each individual fan requires a dedicated drive motor and its power supply circuit. When the heat dissipation demand increases, the increase in the number of fans leads to a synchronous increase in the number of motors, resulting in a significant increase in the total power consumption of the drive unit and making the energy consumption of the entire welding machine too high.

[0004] In view of this, we propose an energy-saving welding machine. Utility Model Content

[0005] Technical problems to be solved The purpose of this utility model is to provide an energy-saving welding machine to solve the problem mentioned in the background art of excessive energy consumption caused by the use of multiple fans in traditional welding machines to meet the high temperature heat dissipation requirements.

[0008] Preferably, a mounting plate is fixedly connected to the movable frame, and a lower connecting block is fixedly connected to the bottom of the mounting plate. A threaded sleeve is connected to the screw through a ball screw pair thread. The threaded sleeve is fixedly connected to the lower connecting block, so that the movable frame can be driven to move along the slide groove when the screw rotates.

[0009] Preferably, an upper connecting block is fixedly connected above the mounting plate, a rotating block is rotatably connected to the upper connecting block, the rotating block is slidably connected to the second rotating rod, a third bevel gear is fixedly connected to the rotating block, and a fourth bevel gear is fixedly connected to the bottom of the first rotating rod, the fourth bevel gear meshing with the third bevel gear.

[0010] Preferably, the rotating block has a central opening so that the second rotating rod can pass through the rotating block. A limit block is fixedly connected to the opening of the rotating block, and a limit groove is formed on the second rotating rod.

Beneficial effects

[0013] This invention uses a single motor to synchronously drive multiple fan blades to rotate and move horizontally, replacing the traditional multi-fan independent motor layout with a single power source. This reduces the energy consumption of multiple drive units, significantly improves the overall energy efficiency, and achieves energy-saving effects.

[0014] This utility model's movable frame drives the fan blade assembly to move horizontally back and forth along the slide groove, expanding the airflow coverage area from static fixed to dynamic scanning, forcing the airflow to penetrate all parts of the radiator evenly, effectively solving the problem of local heat accumulation and improving the heat dissipation effect.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1-6 This utility model provides a technical solution: An energy-saving welding machine includes a welding machine body 1. A ventilation opening 102 is provided on the back plate 101 of the welding machine body 1. A movable frame 2 is slidably disposed at the ventilation opening 102. Multiple fan blades 23 are rotatably connected within the movable frame 2. Each fan blade 23 is fixedly connected to a first bevel gear 9. A motor 3 is fixedly connected to the back plate 101. A screw 4 is rotatably connected to the output end of the motor 3. The screw 4 drives the movable frame 2 to reciprocate. Multiple mounting brackets 10 are fixedly connected to the movable frame 2. Multiple mounting brackets 10 are rotatably connected to a first rotating rod 7. A second rotating rod 11 is rotatably connected to the back plate 101. Multiple second bevel gears 13 are fixedly connected to the first rotating rod 7. The multiple second bevel gears 13 mesh with the multiple first bevel gears 9 respectively. This arrangement reduces space waste, drives multiple fans to rotate through a single rotating rod, and improves space utilization. Furthermore, the screw 4 enables dynamic coverage of the heat dissipation area, improving heat dissipation and thus enhancing energy efficiency to a certain extent.

[0022] Specifically, a dustproof net 103 is fixedly connected to the vent 102, and sliders 21 are fixedly connected to the top and bottom of the movable frame 2. A groove 22 adapted to the size of the slider 21 is provided on the back plate 101. The dustproof net 103 is used to prevent foreign objects from entering the core heat dissipation area and ensure long-term cleanliness. The design of the slider 21 and the groove 22 provides linear guidance for the movable frame 2, ensuring smooth and stable air sweeping action.

[0023] In addition, a mounting plate 6 is fixedly connected to the movable frame 2, and a lower connecting block 62 is fixedly connected to the bottom of the mounting plate 6. A screw sleeve 5 is connected to the screw 4 through a ball screw thread. The screw sleeve 5 is fixedly connected to the lower connecting block 62, so that when the screw 4 rotates, it can drive the movable frame 2 to move along the slide groove 22. This setting allows the motor 3 to drive the mounting plate 6 and multiple fan blades 23 to move when it starts. In actual use, the reciprocating movement of the movable frame 2 can be achieved by alternating forward and reverse rotation of the motor 3.

[0024] Secondly, an upper connecting block 61 is fixedly connected to the top of the mounting plate 6, and a rotating block 8 is rotatably connected to the upper connecting block 61. The rotating block 8 is slidably connected to the second rotating rod 11, and a third bevel gear 14 is fixedly connected to the rotating block 8. A fourth bevel gear 15 is fixedly connected to the bottom of the first rotating rod 7, and the fourth bevel gear 15 is meshed with the third bevel gear 14. This arrangement enables the horizontal axial input to be converted into the vertical axial output, and the power connection is maintained continuously during the movement of the movable frame 2.

[0025] Furthermore, the rotating block 8 has a central opening, allowing the second rotating rod 11 to pass through it. A limiting block 81 is fixedly connected to the opening of the rotating block 8, and a limiting groove 82 is provided on the second rotating rod 11. The limiting groove 82 is used to drive the rotating block 8 to rotate when the second rotating rod 11 rotates. With this configuration, the rotating block 8 can move horizontally while transmitting rotational power through the cooperation of the limiting block 81 and the limiting groove 82.

[0026] Furthermore, a rotating ring 16 with an L-shaped cross-section is fixedly connected to the rotating block 8. The upper connecting block 61 has a rotating groove 161 that matches the size of the rotating ring 16. Both the upper connecting block 61 and the third bevel gear 14 have holes so that the second rotating rod 11 can pass through. This arrangement allows the rotating block 8 to be rotatably connected to the upper connecting block 61, further improving stability.

[0027] Specifically, pulleys 17 are fixedly connected to the second rotating rod 11 and the screw 4. The two pulleys 17 are connected by a transmission belt 18, so that when the motor 3 starts, it can drive multiple fan blades 23 to rotate simultaneously and drive the movable frame 2 and multiple fan blades 23 to move in the horizontal direction. In short, multiple fans can be rotated and moved by one motor 3, which greatly reduces the energy consumption of the welding machine.

[0028] Working principle: When the energy-saving welding machine is working, the starting motor 3 drives the screw 4 to rotate. The screw 4 is driven by the pulley 17 at the end of the screw through the transmission belt 18, which in turn drives the second rotating rod 11 to rotate. The rotational force of the second rotating rod 11 is transmitted through the limiting groove 82 and the limiting block 81 in the rotating block 8, causing the third bevel gear 14 to rotate. This, in turn, drives the fourth bevel gear 15, which meshes with the third bevel gear 14, to rotate the first rotating rod 7. Meanwhile, the multiple second bevel gears 13 on the first rotating rod 7 mesh with the first bevel gears 9 at the shaft ends of each fan blade 23, thus enabling a single power source to rotate. The source drives multiple fan blades 23 to rotate. At the same time, the rotation of the screw 4 is converted into the linear displacement of the screw sleeve 5 through the ball screw pair, which pushes the movable frame 2 to move horizontally back and forth along the slide groove 22 of the back plate 101. The translation of the movable frame 2 causes the airflow generated by the multiple fan blades 23 to continuously scan different sections of the heat dissipation area. Throughout the process, the rotation of the single motor 3 maintains the continuous rotation of the fan for heat dissipation through the bevel gear set, while the screw 4 also realizes the lateral scanning of the heat dissipation unit, which improves the heat dissipation effect of the welding machine and greatly reduces the heat dissipation energy consumption of the welding machine.
