Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, and in particular to an automatic grooving equipment for plastic-coated composite steel pipes. Background Technology

[0002] In the field of pipeline engineering, plastic-coated composite steel pipes are widely used in various fluid transportation systems due to their good corrosion resistance and mechanical properties. When grooving plastic-coated composite steel pipes, the quality of grooving directly affects the sealing and stability of the pipeline connection. Currently, when grooving coated composite steel pipes, it is often necessary to clamp and limit the steel pipes first. However, when dealing with steel pipes of different specifications, the limiting components are difficult to provide stable limiting support for steel pipes of different specifications, which makes it difficult to carry out the subsequent grooving operation accurately and stably, thus affecting the actual grooving quality. Therefore, to solve this problem, we need to consider designing an automatic grooving equipment for coated composite steel pipes. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic grooving device for plastic-coated composite steel pipes. Addressing usability issues, it incorporates a clamping mechanism that enables the limited clamping of steel pipes of different lengths, reducing workload. The limiting mechanism also allows for easy replacement of the columnar support blocks, thus satisfying the requirements for stable support and grooving operations for steel pipes of different diameters, demonstrating good practicality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatic grooving device for plastic-coated composite steel pipes includes a worktable with a grooving machine fixedly connected to its upper end; a clamping mechanism including a rotating shaft rotatably connected to the right side of the grooving machine, a first clamping plate fixedly connected to the right side of the rotating shaft, a columnar support block provided on the right side of the first clamping plate, a movable groove opened at the upper end of the worktable, a telescopic rod installed on the left inner wall of the movable groove, a movable plate fixedly connected to the telescopic end of the telescopic rod, a motor installed on the right side of the movable plate, the output shaft of the motor passing through the movable plate and fixedly connected to a second clamping plate; and a limiting mechanism including a rectangular inner groove opened on the right side of the first clamping plate, a bidirectional threaded rod rotatably connected between the front and rear inner walls of the rectangular inner groove, an L-shaped limiting block threaded at each of the two threaded ends of the bidirectional threaded rod, and two L-shaped limiting grooves opened on the left side of the columnar support block.

[0005] Preferably, the cylindrical support block has an annular pressure groove, and the telescopic rod is a hydraulic telescopic rod.

[0006] Preferably, two guide rods are fixedly connected between the inner walls of the front and rear sides of the rectangular inner groove.

[0007] Preferably, both guide rods pass through the movable plate and are slidably connected to the movable plate.

[0008] Preferably, the front end of the bidirectional threaded rod passes through the rectangular inner groove and is fixedly connected to a rotating block.

[0009] Preferably, both L-shaped limiting blocks are engaged with corresponding L-shaped limiting grooves.

[0010] Compared with the prior art, the advantages of this utility model are as follows: A clamping mechanism is provided. By inserting one end of the steel pipe into the cylindrical support block, and in conjunction with the first clamping plate, telescopic rod, and second clamping plate, the clamping and limiting of plastic-coated composite steel pipes of different lengths can be achieved conveniently and quickly, reducing the actual workload. A limiting mechanism is also provided. By rotating the rotating block, the movement of two L-shaped limiting blocks is controlled.

Overall, it has good practicality. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figures 1-3An automatic grooving device for plastic-coated composite steel pipes includes a workbench 1, with a grooving machine 2 fixedly connected to the upper end of the workbench 1. The grooving machine 2 is existing technology and mainly consists of a frame, motor, transmission system, pressure rollers and other components. By controlling the rotation and downward movement of the pressure roller components on it, and cooperating with the annular grooving 15 on the column support block 5, the plastic-coated composite steel pipes can be grooved. The system also includes a clamping mechanism, which consists of a rotating shaft 3 rotatably connected to the right side of the grooving machine 2. A first clamping plate 4 is fixedly connected to the right side of the rotating shaft 3. A columnar support block 5 is provided on the right side of the first clamping plate 4. An annular groove 15 is provided on the columnar support block 5. The columnar support block 5 can support the inner side of the steel pipe to cooperate with the annular groove 15 for grooving operations. A movable groove 6 is provided at the upper end of the worktable 1. A telescopic rod 7 is installed on the left inner wall of the movable groove 6. The telescopic rod 7 is a hydraulic telescopic rod. By controlling the telescopic rod 7, the second clamping plate can be driven. The holding plate 10 moves toward the first clamping plate 4 to clamp and limit the steel pipe. The telescopic end of the telescopic rod 7 is fixedly connected to the moving plate 8. Two guide rods 16 are fixedly connected between the inner walls of the front and rear sides of the rectangular inner groove 11. Both guide rods 16 pass through the moving plate 8 and are slidably connected to the moving plate 8. A motor 9 is installed on the right side of the moving plate 8. The output shaft of the motor 9 passes through the moving plate 8 and is fixedly connected to the second clamping plate 10. Anti-slip pads (not shown) are provided on both the first clamping plate 4 and the second clamping plate 10 to improve the stability when clamping the steel pipe. The system also includes a limiting mechanism, which consists of a rectangular inner groove 11 on the right side of the first clamping plate 4. A bidirectional threaded rod 12 is rotatably connected between the inner walls of the front and rear sides of the rectangular inner groove 11. The two threaded ends of the bidirectional threaded rod 12 have opposite thread directions. The front end of the bidirectional threaded rod 12 passes through the rectangular inner groove 11 and is fixedly connected to a rotating block 17. Both threaded ends of the bidirectional threaded rod 12 are threadedly connected to L-shaped limiting blocks 13. Two L-shaped limiting grooves 14 are provided on the left side of the columnar support block 5. The two L-shaped limiting blocks 13 cooperate with the corresponding L-shaped limiting grooves 14. By controlling the two L-shaped limiting blocks 13 to be inserted into the corresponding L-shaped limiting grooves 14 and move in opposite directions, the columnar support block 5 can be stably installed. When it needs to be disassembled and replaced in the future, it is only necessary to control the two L-shaped limiting blocks 13 to move towards each other to remove the columnar support block 5.

[0015] In this utility model, during use, one end of the plastic-coated composite steel pipe to be grooved is first inserted into the columnar support block 5, so that the outer side of the columnar support block 5 supports the inner side of the steel pipe. Then, the telescopic rod 7 is activated to drive the moving plate 8 and the second clamping plate 10 to move towards the first clamping plate 4 until the second clamping plate 10 contacts the other end of the steel pipe, thereby cooperating with the first clamping plate 4 to clamp and limit the steel pipe. The entire limiting process is relatively convenient and can meet the clamping and limiting of steel pipes of different lengths, reducing the workload of limiting. After the limiting is completed, the motor 9 is activated to drive the second clamping plate 10 to rotate, which drives the clamped steel pipe to rotate. At the same time, the grooving machine 2 is activated, and the pressure roller component on it is controlled to rotate and move down, cooperating with the annular pressure groove 15 on the columnar support block 5 to perform grooving operation on the plastic-coated composite steel pipe. After the grooving operation is completed, the second clamping plate 10 is controlled to move away from the first clamping plate 4 to recycle the steel pipe. It is worth mentioning that when grooving is required for plastic-coated composite steel pipes of different diameters, the rotating block 17 can be rotated to drive the bidirectional threaded rod 12 to rotate, causing the two L-shaped limiting blocks 13 to move towards each other. Then, the column support block 5 can be removed by pulling it to the right. After removal, a suitable column support block 5 can be selected (this column support block 5 can ensure stable support for the steel pipe of the current diameter). The two L-shaped limiting grooves 14 on the column support block 5 are aligned with the corresponding L-shaped limiting blocks 13 and inserted. Then, the rotating block 17 is rotated again to make the two L-shaped limiting blocks 13 move away from each other, thus achieving stable installation of the column support block 5. The entire installation and removal process is relatively convenient. By replacing the column support block 5, the grooving requirements of plastic-coated composite steel pipes of different diameters can be met, which is quite practical. It should be noted that the wiring of the grooving machine 2, telescopic rod 7 and motor 9 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control, power supply method and wiring layout of the grooving machine 2, telescopic rod 7 and motor 9 will not be explained in detail.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
