Description

Technical Field

[0001] This utility model relates to the field of pipe welding machine technology, and in particular to a pipe welding machine that facilitates the transfer of welded pipes. Background Technology

[0002] A pipe welding machine that facilitates pipe transfer is a specialized piece of machinery designed for welding pipes and enabling easy relocation and adjustment of the pipes. Building upon the functions of a traditional pipe welding machine, it incorporates features that facilitate pipe transfer and fixation, allowing for easier movement, positioning, and securing of the pipes during the welding process, thereby improving welding efficiency and quality.

[0003] A typical pipe welding machine for easy pipe transfer consists of a clamping mechanism, a welding mechanism, and a base. Therefore, during use, the clamping mechanism can firmly clamp the pipe, providing a stable foundation for welding operations. The welding head in the welding mechanism is responsible for releasing an electric arc or high-temperature flame to melt and connect the edges of the pipe. The base serves as the supporting foundation for the entire equipment, bearing all the components of the pipe welding machine.

[0004] However, in some existing devices, the fixing device is mostly a simple clamping structure when fixing the pipe. Although it can initially fix the steel pipe, it lacks precise centering function, which makes the position of the steel pipe easy to shift during welding, affecting the quality and consistency of the weld. Therefore, a pipe welding machine that facilitates the transfer of welded pipes is proposed to solve the above problems. Utility Model Content

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.

[0033] Reference Figure 2 and Figure 3 The present invention provides an embodiment of a pipe welding machine for convenient transfer of welded pipes, comprising a machine body 1, two locking plates 2 slidably connected to the top two sides of the machine body 1, which are designed to fix the two ends of the pipe, a rolling mechanism 3 is provided inside the two locking plates 2, a processing plate 4 is fixedly connected to the top of the machine body 1, which is designed to support the pipe to be processed, a centering mechanism 5 is provided on the top of the machine body 1, and a cleaning mechanism 6 is provided on the outer two sides of the machine body 1.

[0034] The centering mechanism 5 includes a positioning column 51, designed to provide good rotational capability. The bottom of the positioning column 51 is rotatably connected to the top of the body 1. A connecting plate 52 is fixedly connected to the outside of the positioning column 51. The rotation of the positioning column 51 drives the connecting plate 52 to rotate. Rotating rollers 53 are rotatably connected to the top two sides of the connecting plate 52, designed to allow smooth rotation at the top of the connecting plate 52. Support plates 54 are fixedly connected to the outside of the two rotating rollers 53, designed to provide good connection capability. At the same time, the rotation of the rotating rollers 53 drives the support plates 54 to rotate. Support components are rotatably connected to the outside of the two support plates 54. The support components include two fixed columns 55, designed to provide good support capability. The bottom of the two fixed columns 55 is fixedly connected to the top of the two support plates 54. Support rods 56 are fixedly connected to the top of the two fixed columns 55, designed to provide good support capability. At the same time, the rotation of the positioning column 51 drives the support plates 54 to rotate. The rotating connecting plate 52 rotates, causing the rotating roller 53 and the support plate 54 to rotate. Subsequently, the fixed column 55 connected to the support plate 54 drives the two support rods 56 to move closer to each other. The external rotatable connection of multiple extrusion rollers 57 is to the top of the two support rods 56. The top of the support assembly is rotatably connected to multiple extrusion rollers 57, which is designed to provide good auxiliary sliding ability and prevent displacement during reprocessing. Two hydraulic rods 510 are fixedly connected to the top two sides of the machine body 1, which are designed to provide good telescopic ability. The output end of the hydraulic rod 510 is fixedly connected to the support rod 58. The telescopic movement of the hydraulic rod 510 can drive the support rod 58 to move closer to each other, causing the support rods 56 to move closer to each other. At the same time, the positioning column 51 will rotate. The external slidable connection of the hydraulic rod 510 is to the guide ring 59. When the support rod 56 slides, the guide ring 59 can support the rod 56 to slide on the other side away from the support rod 58 outside the hydraulic rod 510.

[0035] Reference Figure 1 and Figure 4The rolling mechanism 3 includes multiple rotating columns 31, designed to provide good rotational capability. The external parts of the multiple rotating columns 31 are rotatably connected to the interior of two locking plates 2. The interior of the two locking plates 2 is provided with multiple placement slots 33, designed to provide good rotational space for the rotating columns 31. The external sides of the multiple rotating columns 31 are rotatably connected to the interior of the placement slots 33. Sliding rollers 32 are fixedly connected to the external parts of the multiple rotating columns 31. When the rotating columns 31 rotate, they drive the sliding rollers 32 to rotate, allowing them to slide after the pipe welding is completed. The cleaning mechanism 6 includes two guide rods 61, designed to provide good guiding capability and sliding space. The external parts of the two guide rods 61 are fixedly connected to the opposite side of the exterior of the body 1. Sliding blocks 62 are slidably connected inside the two guide rods 61, designed to provide good sliding capability, allowing sliding outside the guide rods 61. Telescopic plates 63 are fixedly connected to the tops of the two sliding blocks 62, designed to provide good telescopic capability, allowing sliding through the sliding blocks... The support plate 62 is telescopic, and a support plate 64 is fixedly connected to the adjacent side of the two telescopic plates 63. Its design provides good support capacity. The telescopic plates 63 can extend and retract, causing the support plates 64 to extend and retract. A connecting plate 65 is fixedly connected to the bottom of the support plate 64, providing good connection capacity. A welding head 67 is fixedly connected to the connecting plate 65. The electric arc or high-temperature flame released by the welding head 67 melts and connects the edges of the welded pipes together, forming a strong welded joint. The bottom of the connecting plate 65... The part is fixedly connected to two dust suction ports 66, which are designed to suck up the debris generated during welding by the welding head 67. The outside of the welding head 67 is on the adjacent side of the two dust suction ports 66. Dust suction pipes 68 are provided on the outside of the two dust suction ports 66. After the debris enters the dust suction port 66, it can enter the interior of the dust suction pipes 68. A vacuum cleaner 69 is fixedly connected to the outside of the two dust suction pipes 68. The dust can be collected by driving the vacuum cleaner 69. The bottom of the vacuum cleaner 69 is fixedly connected to the top of the support plate 64.

[0036] Working Principle: During operation, the welded pipe to be processed is first placed in the locking plates 2 on both sides of the top of the machine body 1. At this time, the locking plates 2 can be adjusted to a suitable position through sliding connection to initially fix the two ends of the welded pipe. The hydraulic rods 510 on both sides of the top of the machine body 1 start to work. The support rods 58 at their output ends move closer to each other under the extension and retraction of the hydraulic rods 510, further causing the support rods 56 to move closer to each other. Subsequently, the positioning column 51 rotates, driving the connecting plate 52 to rotate as well. This causes the rotating rollers 53 on both sides of the top of the connecting plate 52 to rotate on their own axis. The rotation of the rotating rollers 53 further drives the externally fixed support plate 54 to rotate. The rotation of the support plate 54 will drive the two support rods 56 to move closer to each other through the fixed column 55 connected to it. At the same time, the multiple extrusion rollers 57 rotatably connected to the top of the support rods 56 will exert an extrusion effect on the welded pipe, so that the welded pipe is accurately centered under the support of the processing plate 4, ensuring the accuracy of the welding position and strengthening the fixing and centering effect of the welded pipe. During the sliding process of the support rod 56, the guide ring 59 slides outside the hydraulic rod 510, ensuring that the support rod 56 can slide stably on the other side away from the support rod 58, thereby maintaining the overall stability and centering accuracy of the centering mechanism 5;

[0037] The welded pipe to be processed is placed inside the clamping plate 2. The clamping plate 2, with the aid of its internal rolling mechanism 3, rotates multiple rotating columns 31 within the placement groove 33, driving the sliding roller 32 to rotate. This facilitates the sliding and initial positioning adjustment of the welded pipe within the clamping plate 2. Simultaneously, the slider 62 slides on the guide rod 61, causing the telescopic plate 63 to extend and retract, thereby moving the support plate 64 and its bottom connecting plate 65, welding head 67, and dust extraction port 66 to the appropriate positions. The welding head 67 begins welding, melting and connecting the edges of the welded pipe. During this process, the dust extraction port 66, under the action of the vacuum cleaner 69, collects welding debris and fumes through the dust extraction pipe 68, keeping the welding area clean.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
