Description

Technical Field

[0001] This utility model relates to the technical field of molding equipment for pipe fittings, and in particular to molding equipment for steel-lined polytetrafluoroethylene (PTFE) pipe fittings. Background Technology

[0002] In industries such as chemical, pharmaceutical, power, electronics, and food processing, the corrosion resistance, high-temperature resistance, and sealing performance of pipeline systems directly affect production safety and efficiency. Traditional metal pipelines are prone to leakage in corrosive media such as strong acids, strong alkalis, and organic solvents, leading to equipment damage, environmental pollution, and even safety accidents. While ordinary plastic pipelines possess corrosion resistance, their insufficient mechanical strength makes them unable to withstand high-pressure or high-temperature conditions. Steel-lined polytetrafluoroethylene (PTFE) pipe fittings, by combining a PTFE lining with a metal matrix, retain the chemical inertness of PTFE (resisting any concentration of strong acids, strong alkalis, and strong oxidants) while utilizing the high strength properties of metal, becoming a core technology for solving material transportation challenges under extreme conditions.

[0003] Currently, the existing molding process for steel-lined PTFE molded pipe fittings is inconvenient for fixing the pipe fitting position and flexibly adjusting the angle. Furthermore, it is not convenient to vibrate and compact the PTFE powder after filling the pipe fitting. The lack of auxiliary processing equipment reduces the convenience of operation and processing efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a steel-lined polytetrafluoroethylene molding pipe fitting forming equipment that can simultaneously produce two different types of pipe fittings by setting two sets of rotating platforms and pressure mechanisms, and can also meet the pressure testing requirements of three-branch water pressure pipelines, reducing the complexity of manual operation and improving work efficiency.

[0005] This utility model discloses a steel-lined polytetrafluoroethylene (PTFE) molding pipe fitting forming equipment, including an operating table and supports, with two sets of supports respectively arranged on both sides of the operating table; it also includes a positioning component, a moving mechanism, a pressure mechanism, a bearing, a rotating platform, a vibration motor, a drive motor, and springs. The bearing is installed on the outer walls of the two sets of supports, and the two sets of rotating platforms are rotatably mounted on the two sets of supports via the bearings. The two sets of vibration motors are respectively installed at the bottom of the outer walls of the two sets of rotating platforms, and the positioning component is provided at the top of the two sets of rotating platforms for clamping and fixing the pipe fittings. The two sets of drive motors are respectively installed on the outer walls of the two sets of supports, and the output ends of the two drive motors are respectively connected to the two sets of rotating platforms. The rotating end of the rotating platform is connected to a support frame equipped with a moving mechanism for hoisting and transporting the processed pipe fittings. A pressure mechanism is mounted on the operating table to pressurize the pipe fittings, with springs mounted on the support. The sandblasted and rust-removed pipe fittings are placed on the rotating platform and clamped in place by positioning components. Then, an inner diaphragm is inserted into the pipe fitting, ensuring a distance of at least 20mm between the diaphragm and the fitting. The opening of the pipe fitting is then sealed with a rubber strip, leaving only one opening open. The drive motor then rotates the rotating platform, causing it to flip the pipe fitting so that the open opening faces upwards. Finally, the open opening of the pipe fitting is... Install the mold at the opening position. After turning on the vibratory motor, the rotating platform vibrates via a spring, causing the pipe fitting to vibrate. At this time, PTFE powder is filled through the unobstructed opening of the pipe fitting. After filling, turn off the vibratory motor and install the underwater pressure mold at the pipe fitting opening. The underwater pressure mold has a jack. Insert the two screws of the puller into the corresponding bolt holes of the pipe fitting opening, flatten the pull tongue, and turn on the hydraulic pump switch. The piston rod of the jack on the underwater pressure mold moves upward, while the underwater pressure mold moves downward, thus compacting the powder inside the pipe fitting. Afterward, remove the puller, jack, and underwater pressure mold, and install the blind flange. After securing the bolts, restart the drive motor to rotate the platform, ensuring the other side of the pipe fitting's sealed opening faces upwards. Remove the sealing strip from the pipe fitting opening, secure the mold, install the mold, and start the vibration motor. Repeat the above procedure to process the pipe fitting opening at that location. After processing, use a moving mechanism to lift the pipe fitting to the pressure mechanism for water pressure testing. Remove the pressurized pipe fitting and use the moving mechanism to unload it. Repeat this process. By setting up two sets of rotating platforms and pressure mechanisms, two different types of pipe fittings can be produced simultaneously, and the pressure testing requirements of three-branch water pipelines can also be met, reducing the complexity of manual operation and improving work efficiency.

The guide rail is mounted on the outer wall of the rotating platform, the L-shaped bracket is slidably mounted on the guide rail, the fastening bolts are fitted between the guide rail and the L-shaped bracket, the adjusting bolts are mounted on the outer wall of the L-shaped bracket, and the lower and upper pipe clamp plates are fitted on the L-shaped bracket via the adjusting bolts. The pipe fitting is placed between the lower and upper pipe clamp plates, and then the lower and upper pipe clamp plates are tightened by rotating the adjusting bolts, thereby clamping and fixing the pipe fitting. The L-shaped bracket can be slidably adjusted to clamp and fix pipe fittings of different lengths. The guide rail and the L-shaped bracket are pressed together by rotating the fastening bolts, making it easier to slide and fix the L-shaped bracket on the guide rail, thereby improving the positioning stability of the pipe fitting.

The main pipeline is installed on the outer wall of the operating platform and connected to an external pressure water supply device. Multiple sets of branch pipes are connected to the main pipeline, and multiple sets of control valves and multiple sets of pressure relief valves are respectively connected to the multiple sets of branch pipes.

Then, an inner diaphragm is placed inside the pipe fitting, ensuring a distance of at least 20mm between the inner diaphragm and the pipe fitting. The opening of the pipe fitting is then sealed with a rubber strip, leaving only one opening open. The drive motor is then controlled to rotate the rotating platform, causing the pipe fitting to flip and face upwards with the open opening facing upwards. A mold is then installed at the open opening of the pipe fitting. The vibration motor is turned on, and a spring drives the rotating platform to vibrate, causing the pipe fitting to vibrate. At this time, PTFE powder is filled through the open opening of the pipe fitting. After the powder filling is complete, the vibration motor is turned off, and the underwater pressure mold is installed at the opening of the pipe fitting.

After processing, the pipe fitting is hoisted to the pressure mechanism by the moving mechanism to be pressurized with water. The compacted pipe fitting is removed and hoisted out by the moving mechanism. The production is carried out in a cycle. By setting up two sets of rotating platforms and pressure mechanisms, two different types of pipe fittings can be produced at the same time. At the same time, the pressurization requirements of three-branch water pressure pipelines can be met, reducing the complexity of manual operation and improving work efficiency.
