Description

Technical Field

[0001] This utility model relates to the field of composite technology, specifically a hydraulic composite machine for steel-lined PTFE pipes. Background Technology

[0002] PTFE-lined steel pipes are pipes with a steel base and an inner lining of polytetrafluoroethylene (PTFE). This type of pipe combines the mechanical strength of steel with the corrosion resistance of PTFE, making it suitable for a variety of applications. PTFE-lined steel pipes are known as the "King of Plastics" because of their excellent temperature and corrosion resistance. They can withstand high temperatures (up to 150℃) and extreme negative pressure conditions, overcoming the limitation of previous PTFE-lined steel pipes and fittings that could not withstand negative pressure.

[0003] During the manufacturing process of PTFE-lined steel pipes, a PTFE tube needs to be inserted into a steel pipe. However, the diameter of the PTFE tube is usually the same as or slightly larger than the inner diameter of the steel pipe, making it difficult to insert the PTFE tube into the steel pipe and thus affecting the efficiency of PTFE-lined steel pipe manufacturing.

[0004] Therefore, we have made improvements to this and proposed a hydraulic laminating machine for steel-lined PTFE pipes. Utility Model Content

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figures 1 to 3 As shown, this utility model discloses a hydraulic laminating machine for steel-lined PTFE pipes, comprising a frame 1, which is U-shaped with its opening facing forward. A first limiting plate 13 and a second limiting plate 14 are provided between the inner walls of the frame 1. A steel pipe 12 is clamped between the first limiting plate 13 and the second limiting plate 14. A cylinder 3 is provided on one side of the second limiting plate 14, and a base plate 15 is fixedly provided on the bottom surface of the second limiting plate 14. The cylinder 3 can drive the second limiting plate 14 and the base plate 15 to move, thereby facilitating the clamping of the steel pipe 12 and the unloading of the laminated steel-lined PTFE pipe.

[0023] During clamping, the first limiting plate 13 and the second limiting plate 14 are not completely attached, but the base plate 15 is located at the connection between the two. Then, the steel pipe 12 is placed between the first limiting plate 13 and the second limiting plate 14. At this time, the bottom surface of the steel pipe 12 is attached to the top surface of the base plate 15. Then, the first cylinder 3 pushes the second limiting plate 14 towards the first limiting plate 13 until the two are attached, thus clamping the steel pipe 12. During unloading, the first cylinder 3 drives the second limiting plate 14 and the base plate 15 to move, so that the composite steel pipe 12 can be unloaded from the bottom of the base plate 15 to the next process.

[0024] The top of the frame 1 is provided with a clamping plate 9, and a polytetrafluoroethylene tube 11 is clamped on the clamping plate 9. The polytetrafluoroethylene tube 11 corresponds one-to-one with the steel pipe 12. The polytetrafluoroethylene tube 11 is clamped on the clamping plate 9 to facilitate its composite with the steel pipe 12.

[0025] A cylinder 5 is installed on the clamping plate 9. Multiple push rods 8 are located on the top of the clamping plate 9 and are fixedly connected to the connecting plate 7. A hydraulic cylinder 6 is installed on the top surface of the connecting plate 7. A vertical plate is fixedly installed on the top surface of the frame 1, and the hydraulic cylinder 6 is mounted on the vertical plate. The telescopic end of the hydraulic cylinder 6 is fixedly connected to the top surface of the connecting plate 7. The hydraulic cylinder 6 drives the connecting plate 7 to move downwards, thereby driving the push rods 8 to move downwards. The diameter of the push rod 8 is larger than the inner diameter of the polytetrafluoroethylene tube 11 but smaller than its outer diameter. The push rod 8 can push the polytetrafluoroethylene tube 11 downwards, thus merging it with the steel pipe 12.

[0026] Limiting plate 13 is fixedly installed between the inner walls of frame 1, and limiting plate 14 is slidably installed between the inner walls of frame 1. Arc-shaped grooves are respectively formed on the opposite surfaces of limiting plate 13 and limiting plate 14. Mounting plate 2 is fixedly installed between the two side walls of frame 1. Cylinder 3 is fixedly installed on mounting plate 2, and the telescopic end of cylinder 3 is fixedly connected to the front of limiting plate 14. The telescopic movement of cylinder 3 can move limiting plate 14, while steel pipe 12 is engaged within the arc-shaped grooves.

[0027] A bottom frame 16 is fixedly installed between the two sides of frame 1 and on the bottom surface of the second limiting plate 14. Sliding grooves 17 are symmetrically formed on both sides of the top surface of the bottom frame 16. The width of the bottom plate 15 is greater than the width of the second limiting plate 14, and a slider 18 is symmetrically fixedly installed on the bottom surface of the bottom plate 15. The slider 18 is slidably connected to the sliding grooves 17. The middle of the bottom frame 16 is open to prevent it from affecting material feeding. When the bottom plate 15 moves with the second limiting plate 14, it can slide within the sliding grooves 17 via the slider 18, thus serving a guiding function.

[0028] The top surface of the clamping plate 9 is evenly provided with multiple circular grooves, and the polytetrafluoroethylene tube 11 is clamped in the circular grooves. The surfaces of the circular grooves and the arc-shaped grooves are both covered with high-temperature resistant rubber pads, which can increase the tightness of the clamping.

[0029] Fixed plates are symmetrically fixed on both sides of the top surface of frame 1. Cylinder 2 5 is fixed on the fixed plate, and the telescopic end of cylinder 2 5 is fixedly connected to the top surface of card plate 9. The back of card plate 9 is slidably connected to the vertical plate, and the side of the top plate is slidably connected to the fixed plate.

[0030] After the steel pipe 12 is fixed between the first limiting plate 13 and the second limiting plate 14, the polytetrafluoroethylene (PTFE) pipe 11 is clamped onto the clamping plate 9. Then, under the action of the second cylinder 5, the clamping plate 9 and the PTFE pipe 11 on it are moved downward, so that the surface of the PTFE pipe 11 is located inside the heating ring 10. It is heated by the heating ring 10. After heating for a period of time, the hydraulic cylinder 6 drives the connecting plate 7 and the push rod 8 to move downward. The push rod 8 pushes the PTFE pipe 11 into the steel pipe 12 for composite bonding.

[0031] A controller 4 is fixedly installed on one side of the frame 1. Cylinder 3, cylinder 5, hydraulic cylinder 6 and heating coil 10 are all electrically connected to the controller 4. The heating coil 10 contains a coil, which is used for heating. The back of the heating coil 10 is fixed to the vertical plate. The controller 4 is model SC200. The controller 4 can control the start and stop of cylinder 3, cylinder 5, hydraulic cylinder 6 and heating coil 10 respectively.

[0032] During operation, the PTFE tube is fixed by the clamping plate 9 and can move towards the steel pipe 12 under the action of the cylinder 2 5. When the PTFE tube 11 enters the steel pipe 12, its surface will be heated by the heating coil 10 first, so that it can enter the steel pipe 12 to complete the composite process, thereby improving the overall production efficiency of the steel-lined PTFE pipe.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
