Description

Technical Field

[0001] This utility model relates to the field of pipeline corrosion protection technology, and in particular to a flanger suitable for multi-specification steel-plastic composite pipes. Background Technology

[0002] In existing steel-plastic composite pipe flanging production processes, most rely on manual three-jaw pullers or screw tightening to complete the diameter expansion and sizing flanging operations. This simple tooling requires multiple people working together, making mass production difficult. Furthermore, the quality of the finished flanged pipes is hard to control, and the applicable specifications are limited. Manual watering during the cooling process, especially in high-temperature environments, easily leads to various safety accidents. From the perspective of production cost and efficiency, existing processes struggle to increase output, resulting in a lack of market competitiveness. Therefore, there is an urgent need for a new type of flanging machine suitable for multiple specifications of steel-plastic composite pipes. Utility Model Content

[0003] This utility model aims to solve the problems existing in the current steel-plastic composite pipe flanging process, and to provide a flanging machine that can be applied to the flanging of steel-plastic composite pipes of various specifications, improve the flanging quality and production efficiency, and reduce labor costs and safety risks.

[0004] This utility model provides a flanged machine suitable for steel-plastic composite pipes of various specifications. Its core structure is built around the main frame 28. The main frame 28 serves as the basic support structure, with a hydraulic station support plate 2 welded to its front bottom in a horizontal direction, providing a stable installation platform for the hydraulic station 1. The hydraulic station 1 uses a 380V power supply, which can stably output power and provide energy for subsequent hydraulic drive operations.

[0005] A front column channel steel 23 is welded to the front end of the main frame 28, and a rear column channel steel 17 is welded to the corresponding position. The two are connected and fixed at the top by welding a crossbeam channel steel 18, forming a stable frame structure. An electric lifting screw 19 is installed at a suitable position on the crossbeam channel steel 18, and the lower part of it is securely installed with a pipe clamp 29 for the hydraulic cylinder 27. An electric lifting screw switch 20, a hydraulic station switch 22, and a miniature submersible pump switch 21 are respectively installed at corresponding positions on the front column channel steel 23 for easy operation. An oil pipe 30 connects the hydraulic station 1 and the hydraulic cylinder 27, so that the hydraulic oil output from the hydraulic station 1 can be smoothly transmitted to the hydraulic cylinder 27 to drive the hydraulic cylinder push rod 31. At the same time, a spring damper 24 is installed at the front end of the hydraulic cylinder push rod 31. The spring damper 24 can play a buffering role during the push rod movement, protecting the equipment and the workpiece.

[0006] The dovetail groove guide rail 9 is welded to the main frame 28, with sufficient space reserved between it and the rear column channel steel 17 for subsequent operation. The clamping plate 14 is welded to the dovetail groove guide rail slider 32. The positive and negative lead screws 12 are mounted on the fixing ring 33 welded to the dovetail groove guide rail slider 32, and the handwheel 10 is mounted at the end of the positive and negative lead screws 12. By rotating the handwheel 10, the operator can drive the positive and negative lead screws 12 to rotate, thereby causing the clamping plate 14 to open and close along the dovetail groove guide rail slider 32, thus accommodating the placement of steel-plastic composite pipes of different diameters.

[0007] The lower part of the drag rail 11 is equipped with drag rail wheels 34, which are freely placed on the square tube 35 of the main frame, forming the guide rail of the drag rail 11, allowing the drag rail 11 to move freely back and forth. In this way, the drag rail 11 can support steel-plastic composite pipes 13 of different lengths according to actual needs. In terms of installation design, it is ensured that the upper surface of the drag rail 11 is level with the upper surface of the dovetail groove guide rail 9, thereby ensuring that the steel-plastic composite pipe 13 placed on it remains in a horizontal state, providing a stable foundation for subsequent flanging operations.

[0008] When performing the flanging operation of steel-plastic composite pipes, first place the flanges 8 of different specifications of steel-plastic composite pipes on the dovetail groove guide rails 9 and clamp them between the clamping plates 14. Start the hydraulic station foot switch 3, and the hydraulic station 1 transmits hydraulic oil to the oil cylinder 27 through the oil pipe 30, driving the oil cylinder push rod 31 to move the spring damper 24 forward. At this time, the operator holds the expansion mold 26 and, under the push of the oil cylinder push rod 31, pushes the expansion mold 26 into the plastic pipe opening 16 to be flanged. At the same time, use a flame to heat the plastic pipe opening 16 to make it reach the deformation temperature, and then gradually push the expansion mold 26 into the appropriate position of the plastic pipe opening 16 to complete the expansion operation.

[0009] After the diameter expansion is completed, the sizing mold 25 is replaced, and the sizing mold 25 is pushed into the appropriate position of the plastic pipe opening 16 by the hydraulic cylinder push rod 31. After a certain period of time, the pipe opening is shaped. Then, the miniature submersible pump switch 21 is turned on, and the miniature submersible pump 5 placed in the water tank 4 starts to work, drawing water out of the water tank 4 and cooling the plastic pipe opening 16 through the water spray pipe 15. A water baffle 7 is set on the main frame 28 to effectively block the cooling water and prevent it from flowing out. The cooling water flows back to the water tank 4 located in the middle of the main frame 28 through the drain outlet 6, realizing recycling.

[0010] Through the above series of operations, this utility model achieves the flanging of steel-plastic composite pipes of various specifications. Throughout the process, the hand-cranked forward and reverse screws drive the clamping plates to open and close, clamping and fixing steel-plastic composite pipes of different diameters; the position of the drag rail 11 is adjusted to accommodate steel-plastic composite pipes of different lengths; the electric lifting screw 19 is used to adjust the height, driving the hydraulic cylinder 27 to ensure that the spring damping 24 at the front end of the hydraulic cylinder push rod 31 remains horizontal and concentric with the steel-plastic composite pipes of different specifications. Simultaneously, the micro-pump circulating water automatic cooling system replaces the traditional manual cooling operation, not only improving operational safety but also significantly saving manpower and resources, and effectively improving the quality and efficiency of the steel-plastic composite pipe flanging operation.

[0011] In addition, the rear column channel steel 17 has slots at the top and bottom of the center to ensure that the hydraulic jack can pass smoothly; the relative positions of the front column channel steel 23 and the rear column channel steel 17 are precisely designed according to the length of the oil cylinder 27 to ensure that the oil cylinder 27 can be installed and operated normally; the expansion mold 26 and the sizing mold 25 are available in various specifications to meet the flanging requirements of steel-plastic composite pipes of different specifications.

[0015] This utility model relates to the field of steel-plastic composite pipe processing equipment, specifically disclosing a flanging machine suitable for steel-plastic composite pipes of various specifications, aiming to solve the problems of narrow applicability and low efficiency of manual operation of existing equipment. Detailed Implementation

[0016] The aforementioned multi-specification steel-plastic composite pipe flanging machine uses a main frame 28 as its core support structure. A hydraulic station support plate 2 extends horizontally to the bottom front end of the main frame 28 for mounting a 380V hydraulic station 1, providing a stable power source for the equipment. A front column channel steel 23 is welded to the front end of the main frame 28, and a rear column channel steel 17 is welded to the corresponding position. The two are connected at their upper parts by a welded crossbeam channel steel 18, forming a stable frame. An electric lifting screw 19 is installed at a suitable position on the crossbeam channel steel 18. The lower part of the electric lifting screw 19 is secured to the cylinder 27 using pipe clamps 29. An electric lifting screw switch 20, a hydraulic station switch 22, and a miniature submersible pump switch 21 are installed on the front column channel steel 23 for easy operation and control. An oil pipe 30 connects the hydraulic station 1 to the cylinder 27, driving the cylinder push rod 31 to move. A spring damper 24 is installed at the front end of the cylinder push rod 31, which provides a buffering effect during operation, protecting the equipment and workpiece.

[0017] Dovetail groove guide rails 9 are welded onto the main frame 28, with reserved space between them and the rear column channel steel 17. Clamping plates 14 are welded onto the dovetail groove guide rail slider 32. Positive and negative lead screws 12 are mounted on fixing rings 33 welded to the dovetail groove guide rail slider 32. Handwheels 10 are fitted to the ends of the positive and negative lead screws 12. Operators rotate the handwheels 10 to rotate the positive and negative lead screws 12, causing the clamping plates 14 to open and close along the dovetail groove guide rail slider 32, thus accommodating the placement of steel-plastic composite pipes 13 of different diameters. A drag rail wheel 34 is installed at the bottom of the drag rail 11, resting on the square tube 35 of the main frame, allowing the drag rail 11 to move freely back and forth to support steel-plastic composite pipes 13 of different lengths. The upper surface of the drag rail 11 remains horizontal with the upper surface of the dovetail groove guide rail 9, ensuring stable placement of the pipes.

[0018] During the actual flanging operation, the steel-plastic composite pipe flange is placed on the dovetail groove guide rail 9 and clamped between the clamping plates 14. The foot switch 3 of the hydraulic station is activated, and the hydraulic station 1 drives the oil cylinder push rod 31 to move the spring damper 24 forward, pushing the expansion mold 26 into the plastic pipe opening 16 which has been heated to the deformation temperature by the flame to achieve expansion. After expansion, the sizing mold 25 is replaced, and the pipe opening is continued to be shaped. Then the micro submersible pump switch 21 is activated, and the micro submersible pump 5 in the water tank 4 draws out water, which is then cooled on the plastic pipe opening 16 through the water spray pipe 15. The water baffle 7 blocks the cooling water, allowing it to flow back to the water tank 4 through the drain outlet 6 for recycling.

[0019] This invention utilizes a hand-cranked forward and reverse screw 12 to adjust the clamping plate 14, enabling clamping of pipes with different diameters. A movable guide rail 11 adapts to pipes of varying lengths. An electric lifting screw 19 adjusts the height of the hydraulic cylinder 27 to ensure it is horizontal and concentric with the pipe. Combined with a micro submersible pump 5 and an automatic circulating water cooling system, this invention replaces traditional manual operation, improving operational safety, reducing manpower and material consumption, and significantly enhancing the quality and efficiency of flanging the steel-plastic composite pipe 13. Furthermore, the rear column channel steel 17 has grooves at its center to ensure the passage of the hydraulic cylinder push rod 31. The relative positions of the front column channel steel 23 and the rear column channel steel 17 are designed according to the length of the hydraulic cylinder 27. The invention also incorporates various specifications of expansion molds 26 and sizing molds 25, further enhancing the equipment's adaptability to different pipe specifications.
