Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically to a welding device for ultra-thin stainless steel pipes. Background Technology

[0002] Ultra-thin stainless steel pipes refer to stainless steel pipes with a wall thickness to outer diameter ratio of no more than 6%. They are typically used for fluid transportation and are characterized by corrosion resistance, high temperature resistance, and long service life.

[0003] In the prior art, such as the application with application number 202420954227.9, which discloses a stainless steel pipe welding device, the device achieves the effect of fixing pipes of different lengths by adjusting the distance between two fixing plates. After the weld seam is welded, the turntable can be driven by a motor to rotate, thereby making the adjusting plate rotate synchronously. When the pipe is fixed, the weld seam and the welding gun will be misaligned, thus exposing the unwelded part. The user does not need to manually adjust the angle of the pipe, thereby improving the welding efficiency of stainless steel pipes and the automation of the device.

[0004] However, in the existing technology, such as the stainless steel pipe welding device mentioned in application number 202420954227.9, the need to manually clamp and fix the pipe increases the labor output and reduces the efficiency of pipe welding; at the same time, the inability to quickly unload the pipe after welding also reduces the efficiency of pipe welding.

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] To address the problems existing in the prior art, this embodiment provides the following technical solution: an ultra-thin stainless steel pipe welding device, comprising an operating table 1 and a clamping mechanism 3. The clamping mechanism 3 is symmetrically arranged on the upper side of the operating table 1, which can clamp and fix the pipe 2 to be welded, ensuring the welding accuracy of the pipe 2. At the same time, it can also allow the clamped pipe 2 to rotate, thereby improving the welding efficiency. In addition, a welding adjustment mechanism 4 is provided, which is located above the center of the operating table 1. Before welding the pipe 2, it can align the welding points of the two pipes 2, ensuring that the welding point of the pipe 2 is accurately located under the welding torch 5, further improving the welding accuracy of the pipe 2. Furthermore, a rapid unloading mechanism 7 is provided, which is located on the lower side of the internal cavity of the operating table 1, allowing the welded pipe 2 to be quickly unloaded, thereby improving the efficiency of the pipe 2 welding process.

[0031] like Figure 1 and Figure 4 As shown, a welding torch 5 is installed at the upper middle part of the operating table 1. Two pipes 2 can be welded using the welding torch 5. Therefore, the joint of the two pipes 2 should be located below the welding torch 5. A support frame 41 is installed in the middle of the operating table 1, and the support frame 41 is mounted on the output end of the second push rod 44. Opening the second push rod 44 allows the output end to push the support frame 41 backward, positioning it at the upper middle part of the operating table 1. At this point, the pipes 2 to be welded can be joined together and then placed on the support frame. A docking groove 42 is provided at the upper end of the support frame 41, which can be used to align the docking connection of the pipe 2 with the docking groove 42. At the same time, a laser pointer 43 is provided at the rear of the upper end of the support frame 41. The laser pointer 43 can be turned on and will emit a beam of light. It can be observed whether the beam of light emitted by the laser pointer 43 is shining on the docking connection of the pipe 2. If it is not shining on the docking connection, it means that the docking position of the pipe 2 is not accurate. If the beam of light emitted by the laser pointer 43 is exactly shining on the docking connection of the pipe 2, it means that the docking position of the pipe 2 is accurate.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, after the pipe 2 is connected, the laser pointer 43 is turned off. Clamping blocks 31 are symmetrically arranged on the left and right sides of the outside of pipe 2. The clamping blocks 31 are installed inside the connecting block 32, which is installed at the inner ends of the first push rod 33 and the second push rod 34. Simultaneously, the outer ends of the first push rod 33 and the second push rod 34 are rotatably connected to the fixing frame 37. The inner side of the first push rod 33 is rotatably connected to the connecting rod 35, which is rotatably positioned at the output end of the first electric push rod 36. The first electric push rod 36 is installed inside the fixing frame 37. The first electric push rod 36 can be opened, and the output end of the first electric push rod 36 can pull the connecting rod 35 to move outward. At this time, the two ends of the connecting rod 35 will pull the connected first push rod 33 to rotate inward. At this time, the second push rod 34 will also rotate inward. When the first push rod 33 and the second push rod 34 rotate inward, they can drive the connecting block 32 connected to the inner end to move together. At the same time, the clamping block 31 installed on the inner side of the connecting block 32 will also move. The clamping block 31 moves inward and can fit against the outside of the pipe 2, thereby clamping and limiting the pipe 2.

[0033] After the pipe 2 is clamped, the second push rod 44 can be opened again, so that its output end pulls the support frame 41 to move forward and separate it from the attached pipe 2. Then, the electric push rod installed on the top of the welding gun 5 can be opened, so that its output end can push the welding gun 5 to fit with the part of the pipe 2 to be welded, thereby welding the pipe 2. In addition, the outer end of the clamping mechanism 3 is connected to the first motor 38. When the first motor 38 is turned on, the entire clamping mechanism 3 can drive the clamped pipe 2 to rotate, thereby enabling welding of the pipe 2 from all directions.

[0034] Secondly, chip suction ports 61 are set on the left and right sides of the outside of the welding torch 5. The chip suction port 61 is connected to the chip collection and filter box 62 through the chip suction pipe at the lower rear side. The exhaust fan 63 installed at the rear of the chip collection and filter box 62 can be turned on, and the chip suction port 61 will generate suction to absorb the welding fumes and welding slag. The fumes and welding slag will enter the inside of the chip collection and filter box 62 through the chip suction pipe between the chip suction port 61 and the chip collection and filter box 62. The filter screen set inside the chip collection and filter box 62 can filter the fumes and make them harmless to be discharged. The collected welding slag will be collected in the inside of the chip collection and filter box 62 for easy cleaning later.

[0035] like Figure 2 , Figure 5 and Figure 6As shown, the center of the operating platform 1 is hollow, and movable plates 71 are symmetrically arranged on the lower side. After the pipe 2 is welded, movable blocks 74 installed on both sides of the movable plate 71 are located inside the fixed grooves 75 installed on the lower side of the operating platform 1. The left side of the movable block 74 is threadedly connected to a double-acting screw 72, and the right side is slidably connected to a support shaft 76. This allows the second motor 73 connected to the front end of the double-acting screw 72 to be turned on, causing the double-acting screw 72 to rotate. This allows the movable blocks 74 and the movable plate 71 to move in opposite directions. When the movable plate 71 moves outward... After the movement, there is no obstruction under the cavity of the operating table 1. At this time, the clamping mechanism 3 that clamps the pipe 2 can release the pipe 2, and the pipe 2 will fall downward. A discharge ramp 77 is set on the lower side of the moving plate 71. The discharge ramp 77 is set in a slope, and a rubber block 78 is set between the lower side of the discharge ramp 77 and the lower rear side of the operating table 1. That is, when the pipe 2 falls downward, it will pass through the discharge ramp 77. The rubber block 78 set below the discharge ramp 77 will play a buffering role, allowing the pipe 2 to enter the interior of the collection box 79 along the slope of the discharge ramp 77.

[0036] The motor model mentioned above is Z4-180-21, and the electric linear actuator model is HB-DJ801.

[0037] The working principle of this ultra-thin stainless steel pipe welding device is as follows: A welding adjustment mechanism 4 is set on the upper side of the middle of the operating table 1 to calibrate the joint of the pipe 2 so that it is located under the welding torch 5. Then, the clamping mechanism 3 is used to clamp and limit the pipe 2, which can ensure the accuracy of the welding torch 5 when welding the pipe 2. At the same time, a first motor 38 is set on the outside of the clamping mechanism 3, which can make the clamping mechanism 3 and the pipe 2 rotate, so that the pipe 2 can be welded in all directions and quickly. A waste slag collection component 6 is set on the outside of the welding torch 5. During the welding of the pipe 2, the waste slag collection component 6 can absorb the flue gas and welding slag, so that the flue gas can be filtered and discharged harmlessly, and the welding slag can be uniformly absorbed and treated. After the welding is completed, the pipe 2 can be quickly unloaded by the fast feeding mechanism 7 set on the lower side of the cavity of the operating table 1.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
