Description

Technical Field

[0001] This utility model relates to the technical field of alloy tube welding and forming equipment, specifically a thin-walled alloy tube continuous forming equipment. Background Technology

[0002] Thin-walled alloy pipes are thin-walled tubes made of alloy steel or titanium alloy, produced by cold drawing process, and widely used in chemical equipment, mechanical structural parts and other fields. Thin-walled alloy pipes require welding forming process during the forming process.

[0003] For example, publication number CN 219986715 U (titled "A Thin Square Tube Welding and Forming Device") includes a base. Two support plates are movably mounted on the top of the base. A top plate is fixedly mounted on the top of each support plate, and a welding torch is fixedly mounted on the bottom of each top plate. A positioning plate is fixedly mounted on the bottom of each top plate next to the welding torch. An L-shaped limiting plate is slidably mounted on the side of each positioning plate, and a first telescopic rod is fixedly mounted on the side of each L-shaped limiting plate. The square tube is driven to move slowly inside the base via the bottom of the base, allowing the welding torch to continuously weld the square tube. The side of the square tube slides along the surface of the roller, causing the roller to rotate at the bottom of the fixed plate. The roller clamps and fixes the square tube, reducing frictional resistance and preventing excessive clamping force. This facilitates the movement of the square tube and makes welding more convenient. The side end of the fixing plate presses against the connecting frame, causing the connecting frame to rotate on both sides of the first support plate. This allows the first support plate to slide on one side of the second telescopic rod. The side end of the first support plate presses against the top of the second telescopic rod, forcing the second telescopic rod to extend and retract inside the second support plate. Then, the second telescopic rod pushes the first support plate in the opposite direction, causing the first support plate to apply pressure to the fixing plate. The fixing plate drives the roller to continue pressing the side end of the square tube, making it easier to fix square tubes of different shapes and increasing usability.

[0004] The aforementioned square tube welding and forming device uses a rolling pressing mechanism to perform limiting welding on the tube. However, it cannot guarantee continuous welding during the welding process, which results in a significant amount of welding and forming time being spent during loading and unloading, thus affecting the welding and forming efficiency of thin-walled alloy tubes. Therefore, we provide a continuous forming device for thin-walled alloy tubes. Utility Model Content

[0005] The purpose of this invention is to provide a continuous forming device for thin-walled alloy tubes, in order to solve the problem mentioned in the background art that the existing square tube welding forming device performs limited welding on the tube by setting a rolling pressing mechanism, but cannot guarantee continuous welding during the welding process, resulting in a lot of welding forming time being occupied during loading and unloading, which affects the welding forming efficiency of thin-walled alloy tubes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a thin-walled alloy tube continuous forming device, including a support platform, two bearing frames welded to the upper end of the support platform, a hexagonal roller between the two bearing frames, two sleeve frame seats welded at equal intervals on the six outer walls of the hexagonal roller, and a thin-walled alloy tube is placed inside the inner bearing. Also includes: The sliding guide groove is located on one side of the socket frame. The sliding guide groove and the hexagonal roller are integrated into one structure. The sliding guide groove is equipped with a threaded screw, and a screw slider is movably mounted on the threaded screw. The sleeve end seat is sleeved and disposed at one end of the thin-walled alloy tube, and a bearing shaft seat is welded to the upper end of the lead screw slider. A rotating shaft is disposed on one side of the bearing shaft seat, and a connecting rod is disposed between the rotating shaft and the sleeve end seat. The two ends of the connecting rod are welded to the rotating shaft and the sleeve end seat respectively.

[0007] Preferably, a placement frame is provided on one side of the hexagonal roller. The placement frame and the support platform are an integral structure. An electric welding machine is provided below the placement frame. A welding gun is provided above the electric welding machine through a wiring connection. The welding gun is inserted and placed in the placement frame.

[0008] Preferably, the bearing shaft seat has a through shaft rotatably connected inside, the through shaft and the rotating shaft are an integral structure, and a limit ring block is welded on the outer wall of the through shaft.

[0009] Preferably, bearing seats are fixedly installed on the inner walls of both bearing frames by screws, and mounting shafts are rotatably installed inside the bearing seats. The two mounting shafts and the hexagonal roller are integrated into one structure.

[0010] Preferably, a linkage handle is provided at one end of the sliding guide groove, and the linkage handle is connected to the threaded screw inside the sliding guide groove via a coupling.

[0011] Preferably, an inner bearing is welded onto the inner wall of the sleeve frame, and the thin-walled alloy tube is rotatably connected to the sleeve frame through the inner bearing.

[0012] Preferably, a belt conveyor is provided on the other side of the hexagonal roller, and the outer frame of the belt conveyor is welded to the support platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a welding torch to weld two thin-walled alloy tubes at their contact points. During the welding process, the two thin-walled alloy tubes are rotated for circumferential welding. After the two thin-walled alloy tubes are welded and formed, the hexagonal roller is rotated 60 degrees, allowing the next set of thin-walled alloy tubes to take over the position of the previously welded tubes, achieving continuous welding. This overcomes the problem that existing square tube welding and forming devices, which use a rolling pressing mechanism to limit the welding of the tubes, cannot guarantee continuous welding during the process. This results in a significant amount of welding and forming time being spent on loading and unloading, thus affecting the efficiency of thin-walled alloy tube welding and forming.
