Description

Technical Field

[0001] The invention relates to the field of pipeline processing, and in particular to a pipeline processing assembly line. Background Art

[0002] During the production process of the pipe (A), it is generally necessary to process the pipe end, such as flanging, reinforcement, marking and other processes. During the processing, a single pipe (A) needs to be placed on the processing station and then processed by the equipment.

[0003] In the prior art, when processing the pipe (A), it is necessary to manually place the pipe (A) on the workstation, and then manually take down the processed pipe (A) and stack it, which is time-consuming and labor-intensive, and inefficient. Alternatively, a large pipe (A) to be processed is placed on the workstation by a hoist and processed, which also requires human participation and has the problem of low efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a pipeline processing line for automatically processing the pipe end of the pipeline.

[0005] To achieve the above-mentioned purpose, the scheme of the present invention is: a pipeline processing production line, including an inclined tube material rack for placing pipelines and rolling the pipelines along its inclined surface, a material picking device for transferring a pipeline is arranged at the lower end of the tube material rack, a driving device for radially positioning and axially conveying the pipeline is arranged downstream of the discharge end of the material picking device, a pipe end processing device is arranged in the conveying direction of the driving device, and a transfer device for transferring the pipeline is arranged between the material picking device and the driving device and between the driving device and the storage rack.

[0006] In this way, each workstation can work independently, and the transfer device will transfer the pipe A on each workstation to other workstations. The driving device on the workstation will transport the pipe to the pipe end processing device and then drive the processed pipe to exit the processing station, and then place it on the storage rack for subsequent packaging or other processing procedures. The system does not require manual participation throughout the process, and different devices can work separately to realize assembly line production with high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 , 2 4 is a schematic diagram of the structure of the present invention;

[0008] Figure 3 for Figure 2 A partial enlarged view of . DETAILED DESCRIPTION

[0009] A pipeline processing production line includes an inclined tube loading stand 10 for placing a pipeline A and rolling the pipeline A along its inclined surface, a feeding device 20 for transferring a pipeline A is arranged at the lower end of the feeding stand 10, a driving device for radially positioning and axially conveying the pipeline A is arranged downstream of the discharge end of the feeding device 20, a pipe end processing device 30 is arranged in the conveying direction of the driving device, and a transfer device 40 for transferring the pipeline A is arranged between the feeding device 20 and the driving device and between the driving device and the storage stand 80.

[0010] In the above scheme, the pipes will roll and accumulate at the lower end of the tube material rack 10. The material taking device 20 takes a pipe A from there and places it on the driving device. The driving device drives the pipe A to the pipe end processing device 30 for processing. After processing, the driving device drives the pipe A back and then places it on the storage rack 80 through the transfer device 40. In this way, each workstation can work independently. The transfer device 40 then transfers the pipe A on each workstation to other workstations. The driving device on the workstation transports the pipe A to the pipe end processing device 30 and then drives the processed pipe A to exit the processing station, and then places it on the storage rack 80 for subsequent packaging or other processing procedures. The system does not require manual participation throughout the process, and different devices can work separately to achieve assembly line production with high production efficiency.

[0011] The transfer device 40 includes a drive shaft 41 whose axis is parallel to the axis of the pipeline A. At least one swing arm 42 is arranged around the drive shaft 41. The suspended end of the swing arm 42 is hinged with a V-shaped support card 43 with its opening facing upwards for supporting the pipeline A. The rotating surface of the V-shaped support card is staggered and arranged with the front and rear pipeline placement positions in the axial direction of the pipeline to avoid interference between the V-shaped support card 43 and the pipeline placement position. When the V-shaped support card 43 moves to the upstream station, it lifts the pipeline A on the upstream station so that the pipeline A moves with the V-shaped support card 43. When the support card moves to the downstream station, it places the pipeline A on the downstream station and continues to rotate with the swing arm 42. The V-shaped support card 43 with its opening facing upwards ensures that the pipeline A on it will not fall off.

[0012] The hinge shaft of the V-shaped support card 43 is connected to the drive shaft 41 through a transmission chain, and the rotation direction of the V-shaped support card 43 relative to the swing arm 42 is opposite to the rotation direction of the swing arm 42, and the transmission ratio is 1: 1. In this way, it can be ensured that the opening of the V-shaped support card 43 always faces upward when rotating with the swing arm 42.

[0013] A material supporting table frame 10 is provided with a material blocking inclined block at its lower end. The material taking device 20 includes a rotating shaft 21 whose axis is parallel to the axis of the pipe A of the shaft core. At least three supporting rods 22 whose rod lengths are perpendicular to the axis direction of their shaft cores are circumferentially and evenly spaced on the rotating shaft 21. When taking materials, the suspended ends of the supporting rods 22 are located in the vertical area bounded by the axes of the first pipe A to be taken and the second pipe A to be taken. A V-shaped material supporting notch 221 is arranged on the back side of the material taking surface of the supporting rod 22. The material taking surface of the supporting rod 22 and the V-shaped material supporting notch 221 of the adjacent supporting rod 22 form a guiding surface for the pipe A. In the above solution, when the supporting rod 22 contacts the pipe A on the material supporting table frame 10, only the center of gravity of one pipe A is on the supporting rod 22. When the supporting rod 22 continues to rotate to generate an inclination, the pipe A will roll from the suspended end of the supporting rod 22 to its root, and then roll from its root to the V-shaped material supporting notch 221 of another supporting rod 22. In this way, the taking out of a single pipe A is completed.

[0014] When the V-shaped material supporting notch 221 reaches the position with the opening facing upwards, a material placing frame 50 is arranged beside it. The material placing frame 50 is provided with a V-shaped driving roller 51 whose roller core direction is horizontal and perpendicular to the axis of the pipe A. In this way, when the V-shaped material supporting notch 221 reaches this position, the pipe A on it can be placed on the material placing frame 50. The supporting rod 22 rotates continuously, and at the same time, the V-shaped driving roller 51 on the material placing frame 50 can adjust the axial position of the pipe A for the subsequent workstations to pick up and process.

[0015] The driving device is an "I"-shaped driving roller 60 whose roller core direction is horizontal and perpendicular to the axis of the pipe A. The "I"-shaped driving roller 60 can more effectively position the pipe A to prevent it from rolling, which is convenient for processing.

[0016] The "I"-shaped driving roller 60 is a lifting roller. A supporting roller 70 whose roller core is parallel to the axis of the pipe A is arranged beside the "I"-shaped driving roller 60. The front and rear supporting rollers 70 together support the pipe A to form a pipe placing position. The midpoint of the connecting line of the roller cores of the front and rear supporting rollers 70 is located on the axial middle plane of the "I"-shaped driving roller 60. When the "I"-shaped driving roller 60 is in the low position, its supporting surface is lower than the supporting surfaces of the front and rear supporting rollers 70. When the "I"-shaped driving roller 60 is in the high position, its supporting surface is higher than the supporting surfaces of the front and rear supporting rollers 70. In the above solution, the axial middle plane refers to the vertical plane at the middle position in the axial direction of the "I"-shaped driving roller 60. When placing the pipe A, the pipe A is supported by the two supporting rollers 70. Only when it is necessary to convey the pipe A, the "I"-shaped driving roller 60 rises to lift the pipe A to the accurate height. In this way, the "I"-shaped driving roller 60 is prevented from being frequently impacted by the placed pipe A, ensuring its accuracy. At the same time, this place can adapt to processing devices of various heights.

[0017] The center of the clamp of the pipe end processing device 30 coincides with the axis of the pipe A on the "I"-shaped power roller 60 located at a high position, and one pipe end processing device 30 is respectively provided at both ends of the pipe A or one is provided at one end of the pipe A. In this way, both ends of the pipe can be processed on the same driving device.

[0018] At least two groups of the driving device and the pipe end processing device 30 are arranged in the pipe transport direction. In this way, multiple pipe end processing devices 30 can be arranged or both ends of the pipe can be processed separately. The material storage rack 80 is tilted, and its high end is connected to the transfer device, and a material stopper is arranged at the low end. The processed pipe A is placed on the material storage rack 80, and at the same time, it rolls along the material storage rack 80 to the low position, so that the subsequent station can take the pipe A from there.
