Description

Technical Field

[0001] This utility model belongs to the field of process tube sealing technology, and in particular relates to a sealing device for the production of process tubes for refrigeration systems. Background Technology

[0002] A sealing device for the production of process tubes in refrigeration systems is a specialized piece of equipment used to seal the process tubes of refrigeration equipment. It seals the ends of the process tubes through mechanical pressing, welding, or heat fusion to ensure the airtightness of the pipeline. This device is used in the production of process tubes because the ports of the process tubes need to be sealed after operations such as vacuuming and refrigerant charging to prevent refrigerant leakage and the entry of outside air and moisture into the system, thereby ensuring the operating efficiency and stability of the refrigeration system and meeting the standard requirements for equipment sealing performance.

[0003] However, the existing equipment can only fix and seal process tubes of a specific size during use. This means that when it is necessary to seal process tubes of different sizes, the equipment cannot adapt to various tube diameter specifications. This not only affects the smooth progress of the sealing operation, but also reduces the process quality due to unstable fixing or substandard sealing, bringing many inconveniences and restrictions to the production process. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing device for the production of process tubes for refrigeration systems. By setting a clamping part, it solves the problem that the device can only fix and seal process tubes of a specific size. This results in the device being unable to adapt to various pipe diameter specifications when sealing process tubes of different sizes is required. This not only affects the smooth progress of the sealing operation, but also reduces the process quality due to unstable fixing or substandard sealing, bringing many inconveniences and restrictions to the production process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a sealing device for producing process tubes for a refrigeration system, comprising a sleeve, and further comprising: a clamping part disposed on the sleeve; a configuration part disposed at the bottom of the sleeve; the clamping part comprising a clamping assembly mounted on the sleeve; and a driving assembly mounted on the clamping assembly; the clamping assembly comprising a hydraulic push rod 1 disposed inside the sleeve, the output end of the hydraulic push rod 1 being fixedly connected to a triangular block, a plurality of connecting rods 1 being hinged to the triangular block, each of the ends of the connecting rods 1 away from the triangular block being hinged to a clamp, a plurality of connecting rods 2 being hinged to the outer wall of the sleeve, each of the ends of the connecting rods 2 away from the sleeve being hinged to a plurality of clamps, and a process tube being disposed on the outer wall of the clamps; wherein, the output end of the hydraulic push rod 1 extends to the outside of the sleeve and is slidably connected to the sleeve.

[0006] Furthermore, the configuration unit includes a heating assembly disposed at the bottom of the sleeve; and a sealing assembly disposed at the bottom of the sleeve.

[0007] Furthermore, the drive assembly includes a worktable disposed at the bottom of the sleeve, a support plate fixedly connected to the top of the worktable, a motor sleeve fixedly connected to the back of the support plate, a motor mounted on the motor sleeve, and a rotating shaft fixedly connected to the output shaft of the motor via a coupling. The front end of the rotating shaft is fixedly connected to the sleeve. The rotating shaft passes through the support plate and is rotatably connected to it. By setting up the drive assembly consisting of the worktable, the support plate, the motor sleeve, the motor, and the rotating shaft, the worktable provides stable support, the motor sleeve fixes the motor, and the output shaft of the motor drives the rotating shaft to rotate via the coupling, thereby driving the sleeve to rotate. The advantage is that through a robust structural design and a reliable transmission method, controllable rotational power is provided for the sleeve, achieving stable rotation of the sleeve, providing the necessary motion basis for related operations, and improving the functionality and reliability of the equipment.

[0008] Furthermore, the heating assembly includes a slide rail fixedly connected to the top of the worktable, a slider slidably connected to the outer surface of the slide rail, a support plate 2 fixedly connected to the top of the slider, a heating tube disposed on the support plate 2, and a driving component disposed on the worktable; wherein, the heating tube is adapted to the process tube. By setting up the heating assembly consisting of the slide rail, slider, support plate 2, heating tube, and driving component, the driving component can drive the slider 1 to slide along the slide rail, thereby moving the support plate 2 and the heating tube, realizing the adaptation and adjustment of the heating tube and the process tube. Its advantage is that the slide rail and slider structure ensures the flexibility and stability of the heating tube position adjustment, and the adaptation to the process tube enables precise heating, improving heating efficiency and targeting.

[0009] Furthermore, the sealing assembly includes a second motor mounted on the top of the workbench. The output shaft of the second motor is fixedly connected to a second rotating shaft via a coupling. A rotating plate is fitted onto the outer wall of the second rotating shaft. A second slide rail is fixedly connected to the top of the rotating plate. A second slider is slidably connected to the outer surface of the second slide rail. A third support plate is fixedly connected to the top of the second slider. A third hydraulic push rod is mounted on the top of the rotating plate. The output end of the third hydraulic push rod is fixedly connected to the third support plate. A balancing component is mounted on the rotating plate. A motor slot is provided on the top of the workbench, and the second motor is located within this slot.

[0010] Furthermore, the quick-release assembly includes a sealing block slidably connected to the support plate three. A screw is threadedly connected to the support plate three, and a knob is fixedly connected to the top of the screw. The bottom end of the screw contacts the sealing block. By setting up the quick-release assembly consisting of the sealing block, screw, and knob, the screw can be rotated by rotating the knob. The screw is then used to push the sealing block to slide on the support plate three through the threaded connection between the screw and the support plate three, thereby achieving quick positioning and disassembly of the sealing block. Its advantage lies in the convenience and stability of the threaded transmission, which ensures reliable fixation of the sealing block after installation and allows for quick disassembly and assembly through simple knob operation, thus improving the convenience of equipment maintenance and operation.

[0011] Furthermore, the driving component includes a second hydraulic push rod fixedly connected to the top of the second hydraulic push rod. The output end of the second hydraulic push rod is fixedly connected to the second support plate. Through the extension and retraction of the second hydraulic push rod, the sliding stroke of the second support plate along the first slide rail can be precisely controlled, thereby flexibly adjusting the relative position of the heating tube and the process tube to achieve efficient adaptation and precise heating. The hydraulic drive has the characteristics of large thrust and high stability, which can not only ensure the working reliability of the heating component, but also simplify the maintenance process through modular design and improve the overall performance of the equipment.

[0012] Furthermore, the balancing component includes an arc-shaped groove formed on the top of the workbench, and a slide rod is fixedly connected to the bottom of the rotating plate; wherein the bottom end of the slide rod extends into the arc-shaped groove and is slidably connected to the arc-shaped groove.

[0013] This utility model has the following beneficial effects: 1. By setting up a clamping part, when in use, the process tube to be sealed is first put into multiple clamps, and then the hydraulic push rod one is activated, which pushes the triangular block forward. Because the triangular block is hinged to multiple connecting rods one, and the other end of the connecting rod one is hinged to the clamp, during the forward movement of the triangular block, the clamp can expand outward with the cooperation of multiple hinged connecting rods two on the outer wall of the sleeve through the transmission of multiple connecting rods one. This setting can be adapted to various pipe diameter specifications, improve the applicability to process tubes of different sizes, and solve the limitation of the original device that can only fix process tubes of specific sizes. 2. After the process tube is fixed by setting the configuration unit, first start motor one, which drives the process tube on the fixture to rotate through shaft one. Then start hydraulic push rod two, which pushes support plate two and heating tube on slider one to approach the process tube along slide rail one for heating. After that, drive the heating tube to reset. Then start motor two, which drives rotating plate and sealing block to rotate through shaft two to seal the process tube. At the same time, hydraulic push rod three can be started to push support plate three to drive sealing block to slide on slide rail two with the help of slider two to adjust the sealing distance, so as to ensure stable and reliable sealing quality for process tubes of different sizes.

After the process tube 216 is fixed by setting the configuration part 3, the motor 224 is started first. The process tube 216 on the fixture 214 is rotated by the rotating shaft 225. Then, the hydraulic push rod 315 is activated to push the support plate 313 and the heating tube 314 on the slider 312 to approach the process tube 216 along the slide rail 311 for heating. After that, the heating tube 314 is reset. Then, the motor 321 is activated and the rotating plate 323 and the sealing block 331 are rotated by the rotating shaft 322 to seal the process tube 216.

[0022] One specific application of this embodiment is as follows: In use, the process tube 216 to be sealed is first placed into multiple clamps 214. Then, the hydraulic push rod 211 is activated, which pushes the triangular block 212 forward. Since multiple connecting rods 213 are hinged to the triangular block 212, and the other ends of these connecting rods 213 are respectively hinged to the clamps 214, during the process of the hydraulic push rod 211 driving the triangular block 212 forward, through the transmission of the multiple connecting rods 213, the clamps 214 are hinged to them. The clamp 214 can expand outward with the cooperation of multiple hinged connecting rods 215 on the outer wall of the sleeve 1. This design allows the device to adapt to various pipe diameter specifications, improving its applicability to process pipes of different sizes and overcoming the limitation of the original device that could only fix process pipes of specific sizes. After the process pipe 216 is fixed, the motor 224 is started first. The motor 224 drives the process pipe 216 held on the multiple clamps 214 to rotate through the rotating shaft 225. Then, the hydraulic push rod 315 is started. Hydraulic push rod 315 pushes the support plate 313 on slider 312 and its heating tube 314 along slide rail 311 towards the process tube 216. Once it reaches the appropriate position and heats the process tube 216, hydraulic push rod 315 is activated to reset the heating tube 314, avoiding interference with the sealing operation of the process tube 216. Next, motor 321 is activated, and motor 321 drives rotating plate 323 and its sealing block 331 via shaft 322 to rotate, thus sealing the heated process tube 216. When sealing with sealing block 331, hydraulic push rod 329 can be activated simultaneously to push support plate 328. Support plate 328, with the help of slider 227, drives sealing block 331 to slide on slide rail 226, allowing sealing block 331 to adjust the sealing distance with process tube 216 in a timely manner. This setting ensures that sealing block 331 applies appropriate pressure and is in the correct position to process tube 216 of different sizes, ensuring the stability and reliability of sealing quality.
