Description

Technical Field

[0001] This utility model relates to the field of metal welding technology, and specifically to a metal material welding device. Background Technology

[0002] Metallic materials refer to the general term for metallic elements or materials with metallic properties that are mainly composed of metallic elements. During the processing of metallic materials, welding is required to combine two or more metal parts by heating, pressurizing, or both, so that atomic or molecular bonds are formed at the joint.

[0003] Existing patent CN219852978U discloses a metal material welding device. By setting a fixed rod, a positioning plate, a mounting groove, and a return spring, it can fix tubular metal materials of different diameters. The return spring's return force pushes the positioning plate to fit against the inner wall of the pipe, thereby tensioning and fixing the pipe, thus enabling the fixing of pipes of different diameters and effectively improving the fixing efficiency of tubular metal materials. By setting a fixed plate, a movable plate, a turntable, a driving gear, a driven gear, and a transmission rod, it can rotate the tubular metal material during welding. When the driving gear rotates, it drives the driven gear to rotate, which in turn drives the transmission rod to rotate, which in turn drives the turntable to rotate, and the turntable to rotate the pipe, thus achieving the rotation of the tubular metal material. This effectively reduces labor, improves welding stability, and ultimately improves welding efficiency.

[0004] The aforementioned patent has certain drawbacks: when rotating and welding long pipes, since the pipes are only clamped and fixed by the end of the device, the main body is in a suspended state. In this state, the pipe joint is prone to radial vibration and positional displacement due to its own weight and rotational inertia, which leads to a decrease in weld accuracy and affects welding quality and reliability. Therefore, a metal material welding device is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problem that when rotating and welding long pipe fittings, since the pipe fittings are only clamped and fixed by the end of the device and the main body is in a suspended state, the pipe fitting connection is prone to radial vibration and positional displacement due to its own weight and rotational inertia, which leads to a decrease in weld accuracy and affects the welding quality and reliability. This utility model provides a metal material welding device.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A metal welding apparatus includes a frame with two movable frames, two adjusting frames, a welding mechanism, and a limiting mechanism. A square tube rod is rotatably mounted on the movable frame, and at least four support rollers are mounted on the square tube rod. One support roller is fixed to the square tube rod, while the remaining support rollers are slidably mounted on the square tube rod. Limiting rings are provided on the two support rollers with the widest spacing. The limiting mechanism is used to limit or release the slidable support rollers. A lifting frame is slidably mounted on the adjusting frame, and multiple V-shaped limiting rollers are rotatably mounted on the lifting frame. Limiting components are provided on the adjusting frame for limiting or releasing the lifting frame. The welding mechanism is used for welding pipe joints.

[0008] Furthermore, a positive and negative lead screw is rotatably mounted on the frame, and two movable frames are slidably mounted on the frame and respectively threaded into the positive and negative thread sections of the positive and negative lead screws.

[0009] Furthermore, the surfaces of the support rollers are all constructed with anti-slip grooves.

[0010] Furthermore, the welding mechanism includes a welding frame slidably mounted on a frame, a cylinder mounted on the welding frame, and a welding torch mounted on the movable end of the cylinder.

[0011] Furthermore, the limiting mechanism includes a fixed frame mounted on the machine frame, a plurality of slide rods slidably mounted on the fixed frame, an annular groove constructed on the support roller, and a plurality of balls that roll in cooperation with the annular grooves movably embedded on opposite sides of the slide rods.

[0012] Furthermore, the fixing frame is provided with a waist hole, and the slide rod is provided with a fixing screw that slides and engages with the waist hole. The fixing screw is threaded with a fixing nut that abuts and overlaps with the fixing frame.

[0013] Furthermore, the limiting component includes a limiting bolt threaded through the adjusting frame, and the free end of the limiting bolt is provided with a rubber block that abuts and overlaps with the lifting frame.

[0014] Furthermore, the adjustment frame is slidably mounted on the frame, the frame has multiple positioning holes, and the adjustment frame is slidably mounted with spring pins that engage with the positioning holes.

[0015] The beneficial effects of this utility model are as follows:

[0016] In use, this utility model supports the pipe fitting with multiple support rollers, limits the pipe fitting axially with a limiting ring, and limits the pipe fitting radially with the cooperation of the support rollers and the limiting rollers. This prevents radial vibration and positional displacement of the pipe fitting at the connection point during rotary welding, ensuring weld accuracy, welding quality and reliability, and thus making it more practical.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figures 1-8As shown in one embodiment of this utility model, a metal material welding device includes a frame 1. The frame 1 is equipped with two movable frames 2, two adjusting frames 3, a welding mechanism, and a limiting mechanism. A square tube rod 4 is rotatably mounted on each movable frame 2, with the axis of the square tube rod 4 being horizontal. A drive motor connected to the square tube rod 4 and an output shaft are fixedly mounted on one of the movable frames 2. Rotation of the output shaft of the drive motor causes the square tube rod 4 to rotate. At least four support rollers 5 are mounted on the square tube rod 4, coaxially distributed. In this embodiment, there are four support rollers 5, one of which is fixed to the square tube rod 4, while the remaining support rollers 5 are slidably mounted on the square tube rod 4. Limiting rings 6 are provided on the two support rollers 5 with the widest spacing. The limiting mechanism is used to limit the sliding... The support roller 5 is limited or released from its limit. In this embodiment, for ease of understanding, the support roller 5 fixed on the square tube rod 4 is named the first roller body. The other three support rollers 5 slidably sleeved on the square tube rod 4 are named the second roller body, the third roller body, and the fourth roller body in order of distance from the first roller body from near to far. The first roller body and the fourth roller body are both coaxially fixed with a limiting ring 6. The two second roller bodies, the two third roller bodies, and the two fourth roller bodies are limited or released from their limits by the limiting mechanism. The adjusting frame 3 is slidably provided with a lifting frame 7. The lifting frame 7 slides in the vertical direction. Multiple limiting rollers 8 distributed in a V shape are rotatably provided on the lifting frame 7. The axis of the limiting rollers 8 is in the horizontal direction. The adjusting frame 3 is provided with a limiting component for limiting or releasing the lifting frame 7. The welding mechanism is used for welding the pipe joint.

[0028] In the initial state, the lifting frame 7 is in its highest position, and is limited by the limiting device. During use, one pipe is first placed horizontally on the two first rollers and two second rollers, so that one end of the pipe abuts against the limiting ring 6 on the first roller. The second roller slides to the side of the pipe, and the limiting mechanism limits the two second rollers. Then, one of the limiting devices releases the lifting frame 7, and the lifting frame 7 falls due to gravity until its limiting roller 8 rolls against the outer surface of the pipe. The limiting device then limits the lifting frame 7 again, thus fixing a single pipe. Next, another pipe is placed horizontally on the two third rollers and two fourth rollers, so that the other pipe abuts against the opposite end of the previous pipe. The fourth roller slides until its limiting ring 6 touches the other pipe. The ends of the pipe are contacted and overlapped, allowing the third roller to slide to the other end near the pipe. The two third rollers and two fourth rollers are limited by the limiting mechanism. Then, the other lifting frame 7 is released by another limiting member. The lifting frame 7 falls due to gravity until the limiting roller 8 on it rolls and overlaps with the outer surface of the pipe. The lifting frame 7 is then limited by the limiting member, thus completing the fixation of the other pipe and the docking of the two pipes. Then, one of the square tube rods 4 is driven to rotate, causing the support roller 5 and the two pipes to rotate together. At the same time, the pipe connection is welded by the welding mechanism. After the welding is completed, the two lifting frames 7 are released by the two limiting members, allowing the lifting frame 7 to slide upward until the limiting roller 8 is away from the pipe. The lifting frame 7 is then limited by the limiting member. Finally, the welded pipe is removed from the support roller 5.

[0029] In summary, when this utility model is used, multiple support rollers 5 support the pipe fitting together, the limiting ring 6 limits the pipe fitting axially, and the support rollers 5 and the limiting rollers 8 cooperate to limit the pipe fitting radially, so as to avoid radial vibration and positional displacement of the pipe fitting at the connection during rotary welding, and ensure the accuracy, quality and reliability of the weld. Therefore, it is more practical.

[0030] like Figure 3 As shown, a further technical solution of this utility model is disclosed. A positive and negative lead screw 9 is rotatably arranged on the frame 1. The axis of the positive and negative lead screw 9 is in the horizontal direction and perpendicular to the axis of the square tube rod 4. Two movable frames 2 are slidably arranged on the frame 1 and are respectively threadedly engaged with the positive and negative threaded sections of the positive and negative lead screw 9. The movable frames 2 slide along the length direction of the positive and negative lead screw 9.

[0031] Referring to the above, during use, the positive and negative screws 9 can be driven to rotate forward or reverse. The two moving frames 2 will slide synchronously in opposite directions due to the action of the positive and negative threads, moving closer or further apart from each other. This adjusts the distance between the two square tube rods 4 to accommodate pipes of different diameters, improving the flexibility and adaptability of use. In actual use, the positive and negative screws 9 can be driven to rotate manually, or a motor can be installed on the frame 1, connecting the output shaft of the motor to the positive and negative screws 9. The rotation of the output shaft of the motor will drive the positive and negative screws 9 to rotate.

[0032] like Figure 4 As shown, a further technical solution of this utility model is disclosed, wherein the surface of the support roller 5 is constructed with anti-slip grooves 10;

[0033] Referring to the above, when the support roller 5 drives the pipe to rotate, the anti-slip groove 10 design can increase the friction, prevent the pipe from spinning freely, and improve the stability of use.

[0034] like Figures 1-5 As shown, the specific structure of the welding mechanism of this utility model is disclosed. The welding mechanism includes a welding frame 11 slidably disposed on the frame 1. The welding frame 11 slides along the length direction of the pipe. In this embodiment, the welding frame 11 is slidably disposed on the frame 1 via an electric slide rail. The electric slide rail is fixed horizontally on the frame 1. The welding frame 11 is fixed on the slider of the electric slide rail. The electric slide rail drives the welding frame 11 to slide along the length direction of the pipe. A cylinder 12 is disposed on the welding frame 11. The cylinder 12 is vertical and fixed on the welding frame 11. A welding torch 13 is disposed at the movable end of the cylinder 12. The welding torch 13 is fixed at the movable end of the cylinder 12.

[0035] Referring to the above, in the initial state, the movable end of the cylinder 12 retracts, and the welding torch 13 is in the highest position. In use, by driving the welding frame 11 to slide, the welding torch 13 is positioned above the pipe fitting connection. Then, the movable end of the cylinder 12 extends, driving the welding torch 13 downward to near the pipe fitting connection. When the pipe fitting rotates, the connection is welded by the welding torch 13. Conversely, after welding is completed, the movable end of the cylinder 12 retracts, driving the welding torch 13 upward to the highest position.

[0036] like Figures 1-4As shown, the specific structure of the limiting mechanism of this utility model is disclosed. The limiting mechanism includes a fixed frame 14 set on the frame 1. The fixed frame 14 is fixed on the frame 1. A plurality of slide rods 15 are slidably arranged on the fixed frame 14. The slide rods 15 slide along the length direction of the tube. The support roller 5 is constructed with an annular groove 16. The annular groove 16 and the support roller 5 are coaxially distributed. A plurality of balls 17 that roll with the annular groove 16 are movably embedded on the opposite side of the slide rod 15. The slide rod 15 is constructed with a movable groove. The balls 17 are movably embedded in the movable groove and cannot be removed from the movable groove. In this embodiment, for ease of understanding, the two second rollers mentioned above are used as examples for explanation.

[0037] Referring to the above, in the initial state, the slide bar 15 is in the initial position, the two second rollers are in corresponding positions, and the slide bar 15 is located in the two annular grooves 16 on the two second rollers. The balls 17 on the opposite side of the slide bar 15 roll in cooperation with the two annular grooves 16 respectively. In use, a pushing or pulling force is applied to the slide bar 15 to make the slide bar 15 slide. During this process, through the cooperation of the balls 17 and the annular grooves 16, the two second rollers slide synchronously. When the second rollers slide to the required position, the slide bar 15 is locked so that it cannot slide, thereby limiting the two second rollers. When the second rollers rotate, they drive the balls 17 to roll together.

[0038] like Figure 3 As shown, the complete structure of the limiting mechanism of this utility model is disclosed. The fixing frame 14 is provided with waist holes 18, which are distributed along the length direction of the tube. The sliding rod 15 is provided with a fixing screw 19 that slides and engages with the waist holes 18. The fixing screw 19 is horizontal and fixed on the sliding rod 15. The fixing screw 19 is threaded with a fixing nut 20 that abuts and overlaps with the fixing frame 14.

[0039] Referring to the above, in the initial state, the fixing nut 20 is loose and away from the fixing frame 14, and the slide bar 15 is in the initial position. When the second roller slides to the required position, the fixing nut 20 is tightened and abuts against the fixing frame 14. At this time, the slide bar 15 cannot slide, so as to lock the slide bar 15.

[0040] like Figure 7 As shown, the specific structure of the limiting component of this utility model is disclosed. The limiting component includes a limiting bolt 21 with a thread passing through the adjusting frame 3. The limiting bolt 21 is in a horizontal direction. A rubber block 22 that abuts and overlaps with the lifting frame 7 is provided at the free end of the limiting bolt 21. The rubber block 22 is fixed at the free end of the limiting bolt 21.

[0041] Referring to the above, in the initial state, the limiting bolt 21 is in the extreme position, the rubber block 22 and the lifting frame 7 are in contact and overlap, and the lifting frame 7 cannot slide, so as to limit the lifting frame 7. When in use, manually reverse the limiting bolt 21 to the initial position, the rubber block 22 moves away from the lifting frame 7, and the lifting frame 7 falls, which can release the lifting frame 7 from the limit. After the welding is completed, manually turn the limiting bolt 21 to the extreme position, the rubber block 22 and the lifting frame 7 are in contact and overlap, and the lifting frame 7 cannot slide, thus limiting the lifting frame 7.

[0042] like Figure 8 As shown, a further technical solution of this utility model is disclosed. The adjusting frame 3 is slidably disposed on the frame 1. The adjusting frame 3 slides along the length direction of the pipe. The frame 1 is constructed with a plurality of positioning holes 23. The positioning holes 23 are vertical and are arranged in an array along the sliding direction of the adjusting frame 3. A spring pin 24 is slidably disposed on the adjusting frame 3 and is engaged with the positioning hole 23. The spring pin 24 includes a pin body that is slidably disposed on the adjusting frame 3 in the vertical direction. A return spring is fixed between the pin body and the adjusting frame 3.

[0043] Referring to the above, in the initial state, the adjusting frame 3 is in the initial position, the pin body is engaged with one of its positioning holes 23, and the return spring is in the natural state. During use, the pin body can be manually pulled up until it exits the positioning hole 23, the return spring is stretched, and then the adjusting frame 3 is slid until the lifting frame 7 is in the middle position of a single pipe. Then the pin body is released, the return spring returns to the natural state, and the pin body is engaged with one of the positioning holes 23 to adjust the position of the adjusting frame 3, so that the limiting roller 8 can act on the middle position of the pipe, further improving the stability of use.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
