Description

Technical Field

[0001] This utility model relates to the technical field of pipeline processing, and in particular to a rotary friction welding device for large-diameter pipelines. Background Technology

[0002] In recent years, my country's energy storage business has become increasingly mature, and the installed capacity has grown rapidly. To ensure that battery packs or power stations can operate stably in a suitable temperature environment, a dedicated thermal management system is needed to maintain the temperature. This requires the connection of pipelines and joints. With the continuous development of thermal management systems, higher requirements have been placed on the production and manufacturing of pipelines.

[0003] In existing technologies, the joints are directly welded to the pipeline during installation, which makes it difficult to meet the welding relative angle requirements of the joints at both ends of the pipeline. When the relative angle deviation is too large, it will interfere with the installation conditions of the client and affect subsequent installation. For large-diameter pipelines, rotary friction welding is usually used. However, there is a lack of rotary friction welding devices on the market that are suitable for large-diameter pipelines and joints, which makes it difficult to meet the continuously rising market demand. Utility Model Content

[0004] To address the problems mentioned above in the background art, this utility model provides a rotary friction welding device for large-diameter pipelines.

[0005] The rotary friction welding device for large-diameter pipelines provided by this utility model adopts the following technical solution:

[0006] A rotary friction welding device for large-diameter pipelines includes a placement frame on which the pipeline is placed. A pipeline clamping mechanism is installed at the front end of the placement frame, which clamps the pipeline and aligns it with a joint. The joint is engaged in a joint conformal welding fixture and is fed by rotation driven by a welding standard machine. A tail plate is provided at the rear end of the placement frame to hold the pipeline. A joint conformal welding fixture is provided on the tail plate, which is positioned opposite to the joint conformal welding fixture. The joint conformal welding fixture works in conjunction with the joint conformal welding fixture to adjust the relative angle of the joints welded at both ends of the pipeline.

[0007] Preferably, both the joint conforming welding fixture and the inner side of the joint conforming fixture are provided with through grooves that conform to the conforming contour of the joint, and one end of the joint is inserted into the through groove to ensure a tight and secure connection.

[0008] Preferably, the placement frame includes a track laid in a straight line, a support frame for supporting the pipeline is provided on the track, and the tail plate is set on the support frame and slides along the track. When welding pipelines of different lengths, the tail plate moves to different positions on the track to lock the pipeline.

[0009] Preferably, the pipe clamping mechanism includes an upper pressure plate and a lower pressure plate. The lower pressure plate is fixed to one side of the placement frame, and the upper pressure plate is fed relative to the lower pressure plate and driven by the output of a cylinder. The upper pressure plate and the lower pressure plate cooperate to clamp the pipe.

[0010] Preferably, adhesive blocks are provided on the inner sides of both the upper and lower pressure plates to increase the friction with the pipeline.

[0011] Preferably, a bracket is provided on one side of the pipe clamping mechanism, and an industrial camera is mounted on the bracket. The industrial camera's acquisition end is aligned with the front section of the pipe and detects the flatness of the pipe end face. The industrial camera is communicatively connected to a host computer located on one side of the welding standard machine.

[0012] Preferably, the joint conformal welding fixture is equipped with a through-beam photoelectric sensor to detect missing joints and prevent errors in joint presence or absence. The through-beam photoelectric sensor is communicatively connected to a host computer located on one side of the welding standard machine.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] 1. This utility model develops a rotary friction welding device to solve the welding problem of pipelines and joints. It can quickly and cost-effectively achieve the welding of pipelines and joints, meet the installation requirements and market demand of energy storage pipelines, and is of great significance for the quality control of mass production of pipeline products.

[0015] 2. The connector is snapped into the connector conformal welding fixture. The pipeline is snapped into the connector conformal fixture. The connector conformal fixture and the connector conformal welding fixture are set opposite to each other. The relative angle of the connectors welded at both ends of the pipeline can be adjusted to prevent the installation conditions of the client from being unsatisfactory due to excessive relative angle deviation.

[0016] 3. The placement rack can hold pipes of different lengths. The tail plate slides along the guide rail and clamps pipes of different lengths to meet the welding requirements of pipe products of different lengths, and can realize quick product changeover.

[0017] 4. By setting up industrial cameras and through-beam photoelectric sensors, photoelectric detection is performed on the flatness of the pipe end face and the installation of the joints to prevent adverse conditions during the welding process and ensure the smooth progress of welding.

[0024] The following combination Figures 1-5 The present invention will be described in further detail below.

[0025] This utility model discloses a rotary friction welding device for large-diameter pipelines.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 A rotary friction welding device for large-diameter pipelines includes a placement frame 1 on which a pipeline 2 is placed. The pipeline 2 is made of nylon. A pipeline clamping mechanism 3 is installed at the front end of the placement frame 1. The pipeline clamping mechanism 3 clamps the pipeline 2 and aligns it with a joint 4. The joint 4 is snapped into a joint conformal welding fixture 5 and fed by rotation driven by a welding standard machine 6. A tail plate 7 is provided at the rear end of the placement frame 1 and snaps the pipeline 2 in place. A joint conformal welding fixture 8 is installed on the tail plate 7 and is positioned opposite to the joint conformal welding fixture 5. The joint conformal welding fixture 8 works with the joint conformal welding fixture 5 to adjust the relative angle of the joints 4 at both ends of the pipeline 2.

[0027] After friction welding one end of pipe 2 to connector 4, the end of pipe 2 with connector 4 welded is snapped into tail plate 7, and the other end of pipe 2 is welded. On tail plate 7, connector conformal welding fixture 8 is installed opposite to connector conformal welding fixture 5. Therefore, the relative angle of connector 4 welded at both ends of pipe 2 can be adjusted to ensure that the relative installation angle of connector conformal welding fixture 5 and connector conformal welding fixture 8 is consistent. At this time, the relative angle of connector 4 at both ends of pipe 2 is less than ±5°, which is within a reasonable range.

[0028] Reference Figure 2 , Figure 3The welding standard machine 6 is equipped with a host computer 17 on one side. The welding standard machine 6 can control welding parameters such as welding depth, rotation speed, feed speed, and holding time. It also monitors welding torque to prevent welding defects. The welding standard machine 6 is connected to the host computer 17. Through integrated transformation, the host computer 17 automatically generates welding records and records production information, which can be traced according to different customer needs.

[0029] Reference Figure 2 , Figure 4 , Figure 5 Both the connector contour welding fixture 5 and the connector contour welding fixture 8 have through grooves 9 on their inner sides that conform to the contour of the connector 4. One end of the connector 4 is inserted into the through groove 9 to ensure a tight fit and prevent the pipe 2 from moving during rotation. When the connector 4 is inserted at the wrong angle, the connector 4 cannot be inserted to the end.

[0030] Reference Figure 1 , Figure 2 The placement frame 1 includes a track 10 laid in a straight line, a support frame 11 for supporting the pipe 2 is provided on the track 10, and a tail plate 7 is set on the support frame 11 and slides along the track 10. When welding pipes 2 of different lengths, the tail plate 7 moves to different positions on the track 10 and clamps the pipe 2. It is suitable for welding pipe products of 100-2500mm.

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The pipe clamping mechanism 3 includes an upper pressure plate 12 and a lower pressure plate 13. The lower pressure plate 13 is fixed on one side of the placement frame 1. The upper pressure plate 12 is fed relative to the lower pressure plate 13 and driven by the output of the cylinder. The upper pressure plate 12 and the lower pressure plate 13 cooperate to clamp the pipe 2 by the control of the cylinder.

[0032] Reference Figure 4 Both the inner sides of the upper pressure plate 12 and the lower pressure plate 13 are provided with rubber blocks 14 to increase friction. A gap of the outer diameter of the pipe 2 is reserved between the upper pressure plate 12 and the lower pressure plate 13. The gap is evenly distributed between the upper pressure plate 12 and the lower pressure plate 13. To avoid damaging the pipe 2, the edges of the pressure plate 12 are chamfered.

[0033] Reference Figure 2 , Figure 3A bracket 15 is provided on one side of the pipe clamping mechanism 3. An industrial camera 16 is installed on the bracket 15. The industrial camera 16 is aimed at the front end of the pipe 2 and detects the flatness of the end face of the pipe 2. The industrial camera 16 is connected to the host computer 17 located on one side of the welding standard machine 6. The industrial camera 16 takes pictures and collects information points at multiple positions of the pipe 2. The picture information is sent to the host computer 17 for analysis and feedback. The host computer 17 automatically calculates the difference between the highest and lowest points in the information points. The equipment will automatically weld when the difference is less than the set value.

[0034] Reference Figure 2 , Figure 4 , Figure 5 The joint conformal welding fixture 5 is equipped with a through-beam photoelectric sensor 18 to detect missing joint 4. The through-beam photoelectric sensor 18 is connected to the host computer 17 located on one side of the welding standard machine 6. The through-beam photoelectric sensor 18 is used to prevent the presence or absence of joint 4. If joint 4 is missing, the display interface of the host computer 17 will alarm and the pipeline 2 and joint 4 will not be welded.

[0035] The implementation principle of the large-diameter pipe rotary friction welding device of this utility model embodiment is as follows: the pipe 2 is placed on the placement frame 1, the tail plate 7 is moved to clamp the pipe 2, the cylinder is operated to adjust the distance between the upper pressure plate 12 and the lower pressure plate 13 to clamp the front end of the pipe 2, the front end of the pipe 2 extends out of the pipe clamping mechanism 3, the connector 4 is inserted into the connector conformal welding fixture 5, the upper computer 17 is operated to perform the missing part detection and the flatness detection of the end face of the pipe 2, after the detection is completed, the welding standard machine 6 automatically drives the connector 4 to rotate and feed, the connector 4 is friction welded to the front end of the pipe 2, the pipe 2 is removed and placed in reverse, one end of the pipe 2 with the connector 4 welded is clamped into the tail plate 7, and the other end of the pipe 2 is welded to achieve the friction welding of the connectors 4 at both ends of the pipe 2.
