Description

Technical Field

[0001] This utility model relates to the technical field of liquid level gauge processing equipment, and in particular to an integrated machine for drawing and flanging fluoropolymer-lined liquid level gauge tubes, which integrates tube drawing, straight tube flanging, and branch tube flanging functions. Background Technology

[0002] Traditional manufacturing processes for PTFE-lined level gauges have numerous drawbacks. Previously, multiple independent machines were used to separately complete steps such as pulling the PTFE tube into the steel pipe, flanging both ends of the PTFE tube, and flanging the branches of the PTFE-lined level gauge. This resulted in large equipment footprints, requiring companies to invest more space for equipment placement. Simultaneously, the operation process was cumbersome, requiring workers to switch between different machines, consuming significant time and effort. Furthermore, errors were prone to occur in the connection between different machines. For example, after the PTFE tube was pulled into the steel pipe, when it was manually transferred to other machines for flanging, the relative position of the PTFE tube and the steel pipe might change, affecting the subsequent flanging quality and reducing the product yield. Operating multiple machines also required more manpower for coordination, significantly increasing labor and time costs. Therefore, developing a user-friendly, integrated PTFE-lined level gauge processing machine has become a critical issue that the industry urgently needs to address. Summary of the Invention

[0003] Pipe pulling structure: A fluoropolymer-lined level gauge pipe pulling and flanging integrated machine is mainly composed of a main frame (41), platform (1), winch (19), gantry frame (12), drag rail (22), dovetail groove slide (4), straight pipe flanging electric push rod (5), lifting column (6), branch flanging electric push rod (15), infrared heater (38), infrared temperature sensor (10), temperature alarm (13) and other components. The main frame (41) serves as the basic support for the equipment. A winch (19) is installed at one end. The base (20) of the winch (19) is firmly fixed to the main frame (41) by winch fixing bolts (43). The wire rope (21) extends from the winch (19) to the other end of the main frame (41), and the end is connected to the inner core (35) of the pipe pulling clamp and the outer ring (34) of the pipe pulling clamp. The winch wireless control switch (29) is a wireless remote control. By pressing the winch wireless control switch (29), the PTFE tube (44) can be accurately pulled into the steel pipe (46). The platform (1) is welded to the other end of the main frame (41). The gantry (12) is fixed to the corresponding position of the platform (1) by gantry bolts (45) to provide a stable and reliable working area for subsequent flanging operations.

[0004] Branch-through flange structure: The branch-through flange electric push rod (15) is hoisted on the right side of the upper beam of the gantry frame (12) via a screw (14). The end of the rod is equipped with a notched clamp (9). The branch-through flange sizing mold (36) and the branch-through flange lifting mold (37) can be switched and hung on the notched clamp (9) at any time according to actual production needs. Pressing the branch-through flange electric push rod switch (26) performs the flange operation on the branch-through fluorine-lined level gauge (27) to be flanged. The distribution box (18) is welded to the upper part of the right column of the gantry frame (12). The infrared temperature sensor display (16) and the infrared heater display (17) are installed inside to facilitate the operator to monitor and adjust the temperature in real time. The temperature alarm (13) is installed in the middle of the upper beam of the gantry frame (12). Once the detected temperature exceeds the set range, it will alarm in time to remind the operator to make adjustments. The magnetic universal bracket (11) is attached to the middle of the right column of the gantry frame (12), and the infrared temperature sensor (10) is clipped to its end. The angle can be flexibly adjusted to ensure that it can be accurately aligned with the branch position of the fluorine-lined level gauge (27) to be flipped, thus ensuring the accuracy of temperature detection. The branch spray nozzle (40) is attached to the middle of the right column of the gantry frame (12) and is used to cool the branch after it is flipped, effectively ensuring the quality of the flipping.

[0005] Straight pipe flange structure: A dovetail groove slide (4) is welded to the left end of the platform. The tail end of the straight pipe flange electric push rod (5) is fixed to the dovetail groove slider (47), and the middle section is fixed on the lifting column support plate (48) of the lifting column (6). When the operator presses the straight pipe flange electric push rod switch (7), the straight pipe flange electric push rod (5) can be extended and retracted. With the handheld expansion mold (33) and sizing mold (32), the flange operation of the straight pipe fluoropolymer-lined level gauge (25) to be flanged can be performed efficiently. The V-shaped pipe support (49) of the straight pipe fluoropolymer-lined level gauge to be flanged is installed on the left side of the drag rail (22), and the V-shaped pipe support (50) of the straight pipe fluoropolymer-lined level gauge to be flanged is installed on the rear end of the platform (1). The two are on the same horizontal line and can stably support the straight pipe fluoropolymer-lined level gauge (25) to be flanged. Based on the difference in center height of the straight tube fluoropolymer-lined level gauges (25) of different specifications to be flipped, the height of the electric push rod (5) for flipping the straight tube can be easily adjusted by simply rotating the lifting column control rocker (8) to make it concentric with the straight tube fluoropolymer-lined level gauge (25) to be flipped, thus ensuring the accuracy of the flipping. The straight tube spray nozzle (39) is attached to a suitable position on the left side of the platform (1) and connected to the outlet of the small submersible pump (30) placed in the water tank (28). By starting the small submersible pump switch (51), the flipped straight tube fluoropolymer-lined level gauge (25) can be cooled down in time.

[0006] Other structures and functions: A pulley (23) is installed under the drag rail (22), and a V-shaped tube support (24) for the PTFE-lined level gauge to be flipped is installed on the right side of the drag rail (22). It is concentric with the tension V-shaped tube support (52) welded to the right end of the platform. It rolls on the main frame (41) through the pulley (23) and can accommodate PTFE-lined steel tubes of different lengths to be flipped. Two flat irons (53) are welded to the front end of the tension V-shaped tube support (52) to place an infrared heater (38) to heat the tube opening of the PTFE-lined level gauge (27) to be flipped after the tube has been pulled, so as to facilitate the subsequent flipping operation. An inner support tube (3) is inserted into the port of the PTFE-lined level gauge (27) to assist in the flipping of the tube. A temperature alarm probe (42) is inserted into the inner support tube (3) to measure the temperature in real time. A water baffle (2) is provided on the platform (1) to effectively collect the water generated during the cooling process and avoid affecting the equipment and working environment. The main frame (41) has 14 casters (31) welded to the bottom, which facilitates the movement of the whole equipment and improves the flexibility of equipment use. Whether it is a small processing workshop or a large production plant, the equipment position can be flexibly adjusted according to the actual production layout and needs.

[0007] Beneficial effects.

[0008] Functional integration for high-efficiency production: The processes of pulling PTFE tubes into steel pipes, flanging both ends of PTFE tubes, and flanging the branches of PTFE-lined level gauges, which originally required multiple machines, are integrated into a single machine, greatly improving production efficiency. This reduces the time wasted due to equipment switching and workpiece transfer in traditional processes, making the entire processing flow of PTFE-lined level gauges more compact and efficient.

[0009] Easy to operate and reduces labor costs: By setting up multiple electric push rods and operating switches, such as the wireless control switch for the winch, the electric push rod switch for straight pipe flanging, and the electric push rod switch for branch flanging, operators can simply press the switch to complete the corresponding action without the need for complicated operating skills and a large amount of manpower, which greatly reduces labor costs and improves the degree of production automation.

[0010] Precise control ensures product quality: Equipped with an infrared temperature sensor and temperature alarm, it can monitor temperature changes in real time and accurately during processing. It can control the temperature within a suitable range according to different materials and process requirements, avoiding edge-flanging quality problems caused by temperature issues, and effectively improving product yield and quality stability.

[0011] Height adjustment to accommodate different specifications: The lifting column control rocker arm can flexibly adjust the height of the electric push rod for flanging the straight tube according to the center height of the fluoropolymer-lined level gauge to be flipped, ensuring concentricity with the fluoropolymer-lined level gauge to be processed. Simultaneously, the pulleys on the drag rail allow the equipment to adapt to PTFE-lined steel tubes of different lengths to be flipped, enabling the equipment to meet the production needs of various specifications of fluoropolymer-lined level gauges, demonstrating strong versatility and adaptability.

[0012] Easy to move and flexible to use: The 14 casters welded to the bottom of the main frame make the whole equipment easy to move, making it convenient to work in different work sites or production lines. The position of the equipment can be flexibly adjusted according to the actual production layout and needs, improving the efficiency and flexibility of equipment use.

[0013] Compact structure and space saving: Integrating multiple functions into one main frame, compared with the traditional multiple independent equipment operating separately, it greatly reduces the equipment's footprint, not only saving production space, but also facilitating equipment installation, maintenance and management, and providing convenience for enterprises to optimize production layout.
