Description

Technical Field

[0001] This utility model relates to the technical field of welding equipment, and in particular to a metal filler welding device. Background Technology

[0002] Structured metal packings include perforated plate corrugated packings, plate mesh corrugated packings, perforated plate corrugated packings, wire mesh corrugated packings, and annular corrugated packings. Before use, the metal packings need to be welded.

[0003] Most existing metal filler welding devices use resistance welding, but due to the large instantaneous current during welding and the open nature of the equipment, there are significant safety hazards.

[0004] In related technologies, a pushing mechanism is set up to push the welded structured packing material out of the work platform, reducing the probability of the operator coming into contact with the structured packing material when it is powered on. At the same time, it is convenient to remove the welded structured packing material. However, it is more troublesome for the operator to place and align the structured packing material. The operator often needs to manually adjust the position of the metal structured packing material. Especially when the operator is leveling the top of the metal structured packing material, the electrodes at both ends come into contact with the metal structured packing material, which is inconvenient to adjust and poses certain safety hazards.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0051] In current technologies, a pushing mechanism is used to push the welded structured packing material out of the work platform. However, this is cumbersome for operators to place and align the packing material, often requiring manual adjustment of its position, which is inconvenient and poses certain safety hazards.

[0052] like Figure 1-6As shown, this utility model embodiment provides a metal filler welding device, including: a working platform 1, on which a hydraulic cylinder 2 is mounted; a first frame 3, slidably connected to the top of the working platform 1, and fixedly connected to the output end of the hydraulic cylinder 2; a second frame 4, fixedly connected to the top of the working platform 1; an electrode 5, disposed on the side of the first frame 3 and the second frame 4 close to each other; and an auxiliary component 6 disposed on the working platform 1. The auxiliary component 6 includes: a dual-axis motor 61, fixedly mounted on the top of the working platform 1; and a lead screw 62, fixedly mounted on the top of the working platform 1. The output end of the dual-axis motor 61 is located, and the threads of the two lead screws 62 are in opposite directions; the first plate 63 is fixedly connected to the top of the work platform 1, and the lead screws 62 are rotatably connected to the first plate 63; the second plate 64 is threaded to the outside of the lead screws 62, and the second plate 64 is slidably connected to the first frame 3 and the second frame 4; the guide rod 65 is fixedly connected to one side of the first plate 63, and the guide rod 65 is slidably connected to the second plate 64; the seat 66 is fixedly connected to one end of the guide rod 65; and the leveling mechanism 67 is located on the top of the second frame 4.

[0053] In use, the operator places the thin metal plates layer by layer on the top of the work platform 1 along the direction from frame 4 to frame 3. Then, the hydraulic cylinder 2 is activated to move frame 3. Multiple thin metal plates are clamped by frame 3 and frame 4. At this time, the electrodes 5 on frame 3 and frame 4 are in contact with the thin metal plates. Multiple thin metal plates are also in contact with each other under clamping. After energizing the electrodes 5, the current flows from one electrode 5 through the plate to another electrode 5. The resistance heat generated by the current flowing through the contact surface of the joint and the adjacent area is used to weld the thin metal plates (the structured metal packing includes perforated plate corrugated packing, plate mesh corrugated packing, perforated plate corrugated packing, wire mesh corrugated packing and annular corrugated packing. By welding multiple corrugated thin metal plates, the structured metal packing is finally formed).

[0054] Before placing the metal sheet, the dual-axis motor 61 is started, driving the lead screws 62 on both sides to rotate. Through the threaded action between the lead screws 62 and the second plate 64, the position of the second plate 64 is adjusted. Since the threads of the two lead screws 62 are in opposite directions, the two second plates 64 will move in opposite directions, thereby adjusting the distance between the second plates 64. This facilitates the operator in aligning the metal sheet between the two second plates 64, saving the operator time required for alignment. Furthermore, the dual-axis motor 61 can be started in both directions to drive the second plates 64 to move back and forth, replacing manual leveling of the metal sheet. After the metal sheet is horizontally aligned, because only the horizontal alignment is performed, and not the vertical alignment, the metal sheet has corrugations and an uneven surface. During placement, the contact between the protrusions on the metal sheet will cause the top of the metal sheet to not be perfectly aligned. The hydraulic cylinder 2 is then activated. The drive unit 3 moves towards the metal sheet, applying pressure (enough to keep the metal sheet vertical without affecting its vertical movement). The operator then holds the handle at the top of the rotating rod 674 (not shown in the diagram) and rotates the rod 674. The roller 675 presses the upward-protruding metal sheet downward, keeping the tops of multiple metal sheets level. The entire leveling process does not require the operator to put their hands on the metal sheet, reducing the probability of injury due to accidental activation of the electrode 5 switch, making it safer. When the height of the roller 675 needs to be adjusted due to different metal sheet heights, the operator loosens the threaded rod 676 so that the rubber pad 6761 at one end of the threaded rod 676 does not rub against the rod 672. Then, the operator pulls the rod 672 until the bottom of the roller 675 is level with the top of a single metal sheet. Finally, tightening the threaded rod 676 completes the height adjustment of the roller 675, which is convenient and quick.

[0055] In some embodiments, the leveling mechanism 67 includes: a fixed ring 671, fixedly connected to the top of the second frame 4; a rod 672, slidably connected to the second frame 4 and the inside of the fixed ring 671; a limiting ring 673, fixedly connected to the outside of the rod 672; a rotating rod 674, rotatably connected to the outside of the limiting ring 673; a roller 675, rotatably connected to the bottom of the rotating rod 674; and a threaded rod 676, threadedly connected to the outside of the fixed ring 671, and the threaded rod 676 passes through the fixed ring 671 and extends to the side of the rod 672, limiting the rod 672 by friction.

[0056] The length of the rotating rod 674 is greater than the distance between the first frame 3 and the second frame 4, ensuring that no matter how many layers of metal sheets are set, as long as the metal sheets are placed between the first frame 3 and the second frame 4, they can be leveled by the roller 675. In order to ensure the quality of welding, the height of the metal sheets must be higher than the height of the first frame 3 and the second frame 4. Therefore, there is no need to consider the situation where the metal sheets are lower than the first frame 3 or the second frame 4, which would prevent the roller 675 from leveling the metal sheets.

[0057] In some embodiments, a rubber pad 6761 is fixedly connected to one end of the threaded rod 676 to increase the frictional force on the rod body 672 when tightening the threaded rod 676, thereby further reducing the probability of the rod body 672 slipping.

[0058] In some embodiments, a lifting assembly 7 is provided inside the work platform 1; the lifting assembly 7 includes: a cylinder 71, which is fixedly installed inside the work platform 1; a push plate 72, which is fixedly connected to the output end of the cylinder 71; and an insulating plate 73, which is fixedly connected to the top of the push plate 72.

[0059] During use, after the metal sheet is welded, the hydraulic cylinder 2 is activated to move the first frame 3 away from the second frame 4. After the first frame 3 is moved to the initial position before work, the cylinder 71 is activated to push the push plate 72 upward, thereby pushing the welded metal sheet upward from the surface of the work platform 1 and separating the metal sheet from the electrode 5 on the second frame 4, reducing the risk to the operator when removing the metal sheet.

[0060] In some embodiments, the lifting component 7 is located at the center of the top of the work platform 1. When the distance between the first frame 3 and the second frame 4 is at its maximum, the push plate 72 can be raised normally to ensure that the electrode 5 on the first frame 3 is separated from the metal plate before the metal plate is lifted, thereby further enhancing the safety of the device.

[0061] In some embodiments, both sides of the first frame 3 and the second frame 4 are slidably connected to the second plate 64 via a sliding groove. The edge of the sliding groove is located on one side of the push plate 72 to prevent the second plate 64 from being adjusted to the top of the push plate 72, which would prevent the push plate 72 from rising normally.

[0062] In some embodiments, there is a gap between the second plate 64 and the electrode 5, and the second plate 64 does not contact the electrode 5 when sliding, so as to prevent the second plate 64 from damaging the electrode 5 when sliding.

[0063] In some embodiments, the second plate 64 is an insulating plate to prevent the second plate 64 from being energized with the metal sheet and the electrode 5, thereby preventing the second plate 64 from being welded to the metal sheet.

[0064] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
