Description

Technical Field

[0001] This utility model relates to the field of steel-lined PTFE pipe production technology, and specifically discloses a steel-lined PTFE pipe flanging equipment. Background Technology

[0002] Steel-lined PTFE pipes and fittings enjoy the reputation of being the "King of Plastics" due to their excellent temperature resistance and corrosion resistance. They are ideal for conveying highly corrosive media such as nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine, aqua regia, mixed acids, bromides, and other organic solvents. Steel-lined PTFE pipes and fittings can operate stably for extended periods under high-temperature and extreme negative pressure conditions. Steel-lined PTFE pipes require a PTFE lining layer inside the pipe and PTFE flanges on the flanges at both ends.

[0003] Chinese patent CN112454876A discloses a steel-lined PTFE pipe flanging device, including a mounting bracket with a support seat for horizontally supporting the PTFE-lined pipe. A flanging mechanism is also provided on the mounting bracket at one end of the PTFE-lined pipe on the support seat. The flanging mechanism includes a mold head that presses the PTFE resin at the end of the PTFE-lined pipe onto a flange. A drive mechanism is connected to the mold head, which drives the mold head to move horizontally. The mold head includes a standby position where it is detached from the flange at the end of the PTFE-lined pipe, and a working position where it is driven by the drive mechanism to contact and engage with the flange at the end of the PTFE-lined pipe. The PTFE flanging operation at the flange at the end of the PTFE-lined pipe on the support seat is achieved through the mold head driven by the drive mechanism, which is safer, saves manpower and resources, and results in higher quality flanging operations.

[0004] The steel-lined PTFE pipe flanging equipment disclosed in the aforementioned document requires operators to manually flip the pipe after flanging one end, and then flanging the other end. This operation is cumbersome, and it cannot stably limit the movement of pipes of different lengths, resulting in poor performance. Therefore, a steel-lined PTFE pipe flanging equipment is needed to solve this problem. Utility Model Content

A slide plate 16 is threadedly connected to the outer wall of the first lead screw 2. A limit mechanism is provided on the upper end face of the slide plate 16.

The output end of the third servo motor 10 extends to the bottom of the portal frame 9 and is fixedly connected to a rotating plate 11. A flange mechanism is provided on the outer wall of the rotating plate 11.

[0026] In this embodiment: the first servo motor 3 is started, the first servo motor 3 drives the first lead screw 2 to rotate, which in turn drives the slide plate 16 to move left and right, and then drives the steel-lined PTFE pipe to move left and right through the limiting mechanism, so that the two ends of the steel-lined PTFE pipe are respectively close to the flanging mechanism for flanging operation.

[0027] The second servo motor 7 is started, which drives the second lead screw 6 to rotate, thereby driving the gantry frame 9 to move up and down. The gantry frame 9 further drives the rotating plate 11 to move up and down, thereby driving the conical flanging mold 12 and the flat flanging mold 14 to align with the pipe for flanging operations.

The threaded rod 20 is rotated, and the threaded rod 20 drives the second limiting plate 19 to move away from the first limiting plate 17, thereby stably limiting the PTFE-lined steel pipe. This utility model can stably limit the PTFE-lined steel pipe of different lengths and has good performance.

[0030] As a technical optimization of this utility model, the flanging mechanism includes a conical flanging mold 12 and a flat flanging mold 14. A first electric push rod 13 is installed on the outer wall of the rotating plate 11. The output end of the first electric push rod 13 passes through the rotating plate 11 and is fixedly connected to the conical flanging mold 12. A second electric push rod 15 is installed on the outer wall of the rotating plate 11. The output end of the second electric push rod 15 passes through the rotating plate 11 and is fixedly connected to the flat flanging mold 14.

[0031] In this embodiment: First, the polytetrafluoroethylene (PTFE) pipe structure of the steel-lined PTFE pipe is heated and softened by a blowtorch. Then, the first electric push rod 13 is activated to drive the conical flanging mold 12 toward the pipe to expand the edge of the PTFE pipe structure. Then, the second servo motor 7 drives the rotating plate 11 to move downward so that the flat flanging mold 14 is aligned with the steel-lined PTFE pipe. The second electric push rod 15 is activated, and the second electric push rod 15 drives the flat flanging mold 14 toward the pipe to flanging the pipe.

[0032] As a technical optimization of this utility model, the upper end surface of the base plate 1 is fixedly connected to the first limiting rod 4 through the support plate, and the slide plate 16 is slidably connected to the first limiting rod 4.

[0033] In this embodiment: the first limiting rod 4 facilitates the limiting of the slide plate 16, so that the slide plate 16 moves stably from left to right.

[0034] As a technical optimization of this utility model, a second limiting rod 8 is fixedly connected to the inner wall of another U-shaped plate 5, and the portal frame 9 is slidably connected to the second limiting rod 8.

[0036] As a technical optimization of this utility model, the outer wall of the second limiting plate 19 is fixedly connected with two symmetrically distributed third limiting rods 21, both of which penetrate the side plate 18 and are slidably connected to the side plate 18.

[0037] In this embodiment, the third limiting rod 21 facilitates the limiting of the second limiting plate 19, making the left and right movement of the second limiting plate 19 stable.

[0039] In this embodiment: the controller facilitates equipment control, improves automation, and saves time and effort.

[0040] The working principle and usage process of this utility model are as follows: First, the PTFE-lined steel pipe is placed in the limiting grooves of the first limiting plate 17 and the second limiting plate 19, so that the flanges at both ends of the PTFE-lined steel pipe are located on opposite sides of the first limiting plate 17 and the second limiting plate 19, respectively. The threaded rod 20 is rotated, causing the second limiting plate 19 to move away from the first limiting plate 17, thus stabilizing and limiting the PTFE-lined steel pipe. Then, the PTFE pipe structure is heated and softened using a blowtorch. Next, the second servo motor 7 is started, causing the second lead screw 6 to rotate, which in turn causes the gantry frame 9 to move up and down along the second limiting rod 8, aligning the conical flanging mold 12 with the pipe. Then, the first electric push rod 13 is started, causing the conical flanging mold 12 to move towards the pipe, expanding the edge of the PTFE pipe structure. Finally, the second servo motor 7 drives the rotating plate 11 downwards, aligning the flat flanging mold 14 with the PTFE-lined steel pipe. The second electric actuator 15 drives the flat flanging mold 14 towards the pipe to flanging it. After flanging one end of the pipe, the second servo motor 7 drives the gantry frame 9 to move upward to the top. Then, the first servo motor 3 is started, which drives the first lead screw 2 to rotate, thereby driving the slide plate 16 to move left and right. This, in turn, drives the PTFE-lined steel pipe to move left and right through the limiting mechanism, bringing the other end of the PTFE-lined steel pipe closer to the flanging mechanism. Next, the third servo motor 10 is started, which drives the rotating plate 11 to rotate, causing the rotating plate 11 to rotate 180°. This, in turn, drives the conical flanging mold 12 and the flat flanging mold 14 to rotate to the other side. Then, the second servo motor 7 drives the gantry frame 9 to move downward, thus performing the flanging operation on the other end of the pipe. This utility model can automatically flanging both ends of the pipe, is highly practical, and can stably limit pipes of different lengths through the limiting mechanism, resulting in good performance.
