Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a high-efficiency welding device. Background Technology

[0002] With the continuous improvement of metal processing technology, the structure of metal equipment is becoming more and more complex, especially with the widespread use of thin metals. However, metal materials have a certain shape after production, and welding technology is particularly important for modifying the structure. Traditional welding technologies include electric arc welding, gas welding, resistance welding, solid phase welding, electron beam welding, laser welding, etc. However, laser welding technology is the most suitable for pipelines. Laser welding can be achieved using continuous or pulsed laser beams, and has the characteristics of low welding surface velocity and large width ratio.

[0003] The shortcomings of existing technologies: Traditional laser welding technology, when welding pipes, is slow because the welding surface is a circular cross-section and welding is done at a single point. In addition, the welding process for single-point welding is uneven or repeated welding, which makes it impossible to achieve the ideal flatness of the pipe weld. The large amount of light and heat released during welding, as well as the metal surface running-in, will produce some metal fragments, which poses certain dangers to the welding operation. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency welding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency welding device, comprising a body, a first motor fixedly mounted on the lower inner surface of the body, a suction fan fixedly mounted on the output end of the first motor, a funnel fixedly mounted on the upper inner surface of the body, a permanent magnet plate fixedly disposed near the lower end of the funnel close to the suction fan, a light-blocking chamber fixedly mounted on the upper end of the funnel, a fixed plate fixedly mounted inside the light-blocking chamber, a return spring steel fixedly mounted on one side of the fixed plate, and a driven wheel movably mounted on the side of the fixed plate near the return spring steel via a bearing. Several sets of welding heads are fixedly installed on one side of the inner end face of the driven wheel. A driving half gear is movably installed on one side of the outer surface of the driven wheel. A second motor is fixedly connected to the outer surface of the driving half gear near the light-blocking chamber via a bearing. A high-voltage box is fixedly installed on one side of the second motor. A support column is fixedly installed at the lower end of the high-voltage box. Two sets of support rods are fixedly installed on one side of the high-voltage box. A telescopic rod is fixedly installed on one side of the outer surface of the support rod. A fixing clamp is fixedly installed at the end of the telescopic rod away from the support rod. A rubber pad is fixedly installed on one side of the inner end face of the fixing clamp.

[0006] Preferably, the surface of the permanent magnet plate is provided with a plurality of pinhole-shaped guide holes, and the two sides of the permanent magnet plate are movably provided with disassembly pins.

[0007] Preferably, the fixing clamp consists of two sets of semicircular rings with the same radius.

[0008] Preferably, the outer surface of the fixed disk is fixedly provided with bayonets on both sides, the gear rings of the driven wheel and the driving half gear are made of conductive material, and the output shaft of the second motor is made of insulating material.

[0009] Preferably, one end of the return spring steel is fixedly installed on one side of the outer surface of the fixed disk, and the other end of the return spring steel is fixedly installed on one side of the outer surface of the driven wheel.

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

[0011] 1. This utility model features a driven wheel with several welding heads mounted at angles to each other on the same circular plane. During laser welding, a second motor drives the driven wheel to rotate via a drive half gear. Contact switches are installed on the gear rings of the drive half gear and the driven wheel. Welding begins when the gear rings mesh, effectively ensuring the flatness and uniformity of the welded circular cross-section. At the same time, multi-point welding makes the welding operation more efficient.

[0012] 2. This utility model also includes a light-proof chamber and a suction fan, which allows the welding operation to take place in a light-proof area, effectively preventing light pollution caused by strong light during welding. At the same time, the suction fan reduces the temperature inside the light-proof chamber and effectively concentrates the metal debris generated during welding. A porous permanent magnet plate is also provided at the lower end of the funnel below the light-proof chamber, which can effectively adsorb the debris and stabilize it. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency welding device, including a body 1. A first motor 2 is fixedly installed on the lower end face of the body 1. A suction fan 3 is fixedly installed on the output end of the first motor 2. A funnel 4 is fixedly installed on the upper end face of the body 1. A permanent magnet plate 5 is fixedly arranged on the lower end of the funnel 4 near the suction fan 3. A light-blocking chamber 6 is fixedly installed on the upper end of the funnel 4. A fixed plate 7 is fixedly installed inside the light-blocking chamber 6. A return spring steel 71 is fixedly installed on one side of the fixed plate 7. A driven wheel 8 is movably installed on the side of the fixed plate 7 near the return spring steel 71 via a bearing. The inner end face of the driven wheel 8 is... Several sets of welding heads 9 are fixedly installed. A drive half gear 10 is movably installed on one side of the outer surface of the driven wheel 8. A second motor 11 is fixedly connected to the outer surface of the drive half gear 10 near the light-blocking chamber 6 via a bearing. A high-voltage box 12 is fixedly installed on one side of the second motor 11. A support column 13 is fixedly installed at the lower end of the high-voltage box 12. Two sets of support rods 14 are fixedly installed on one side of the high-voltage box 12. A telescopic rod 15 is fixedly installed on one side of the outer surface of the support rod 14. A fixing clamp 16 is fixedly installed at the end of the telescopic rod 15 away from the support rod 14. A rubber pad 161 is fixedly installed on one side of the inner end face of the fixing clamp 16.

[0020] Furthermore, the permanent magnet plate 5 has several pinhole-shaped guide holes on its surface, and the permanent magnet plate 5 has movably installed disassembly pins on both sides. By setting the porous permanent magnet plate 5, it will not only not hinder the operation of the suction fan 3, but also adsorb the metal debris absorbed by the suction fan 3 onto the surface of the permanent magnet plate 5, so that it can be stably recycled.

[0021] Furthermore, the fixing clamp 16 is composed of two sets of semicircular rings with the same radius. By setting two sets of semicircular structures, the fixing clamp 16 can change the distance between the two sets of semicircles according to the needs of use, thereby fixing metal pipes of different specifications and making it convenient to use.

[0022] Furthermore, the fixed disk 7 has bayonets fixedly provided on both sides of its outer surface, the driven wheel 8 and the gear ring of the driving half gear 10 are made of conductive material, and the output shaft of the second motor 11 is made of insulating material. The meshing of the driving half gear 10 and the driven wheel 8 enables the welding to work intermittently. At the same time, the installation angle of several sets of welding heads 9 ensures the integrity of the welded circular cross section while effectively saving energy.

[0023] Furthermore, one end of the reset spring steel 71 is fixedly installed on one side of the outer surface of the fixed disk 7, and the other end of the reset spring steel 71 is fixedly installed on one side of the outer surface of the driven wheel 8. By providing the reset spring steel 71, the driven wheel 8, driven by the active half gear 10, can quickly reset after rotating at a certain angle to complete the welding, thus ensuring the stability of the welding angle.

[0024] Working principle: After adjusting the angle of the fixing clamp 16, the pipe to be welded is placed and the power is turned on. One end face of the thin metal pipe to be welded is fixed to the lower end of the welding head 9 of the driven wheel 8. Several sets of welding heads 9 are evenly set at an angle. When the driving half gear 10 meshes with the driven wheel 8, the gear rings mesh with each other to turn on the welding power. The welding head 9 begins to weld the surface to be welded. At the same time, the driving half gear 10 drives the driven wheel 8 to rotate so that the welding is done on a circular cross section, ensuring the integrity and uniformity of the welding surface. When the driving half gear 10 rotates to the non-meshing surface, the return spring steel 71 makes the driven wheel 8 return to its original position. At the same time, the light-blocking chamber 6 can effectively isolate the light pollution caused by the leakage of welding light. The funnel 4 is installed at the lower end of the light-blocking chamber 6 to facilitate the recovery of metal debris during welding. At the same time, the suction fan 3 driven by the first motor 2 can effectively reduce the heat generated during welding and further allow the debris generated during welding to be acted on the upper surface of the permanent magnet plate 5 by the suction fan 3 for stable recovery.
