Description

Technical Field

[0001] This utility model relates to the field of PE pipe flaring, and in particular to a PE pipe flaring device that facilitates feeding. Background Technology

[0002] Polyethylene (PE) pipes are widely used in various fields such as urban water supply, drainage and sewage, agricultural irrigation, industrial fluid transportation, and natural gas transportation due to their excellent corrosion resistance, flexibility, lightweight, and environmental friendliness. During the laying and connection of PE pipes, the pipe ends need to be flared to increase the contact area and enhance the stability and sealing of the pipe connection. Therefore, the flaring device is a key piece of equipment in the PE pipe processing stage.

[0003] Existing PE pipe flaring devices typically employ a single set of fixed clamps, then use a tapered flaring tool to squeeze the PE pipe, while simultaneously using a heating auxiliary assembly to perform the flaring operation.

[0004] However, the clamping mechanisms of existing equipment are mostly designed with a fixed angle, which cannot be flexibly adjusted according to the installation angle of the pipe. The pipe position needs to be repeatedly calibrated to achieve stable clamping, which not only increases the workload of operators, but also easily causes problems such as displacement of the flared part and tearing of the pipe due to clamping deviation. Therefore, a PE pipe flaring device that is convenient for feeding is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a convenient PE pipe flaring device, which aims to improve the problem that the existing technology cannot flexibly adjust according to the pipe installation angle.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a PE pipe flaring device for convenient feeding, comprising an integrated box, an electric actuator fixedly connected to the inner wall of the integrated box, a clamping frame one fixedly connected to the output end of the electric actuator, a clamping frame two connected to the right side of the clamping frame one via a limiting component, the clamping frame one and the clamping frame two being adjustable from 0-270° via the limiting component, opposing threaded rods rotatably connected to the inner walls of both the clamping frame one and the clamping frame two, threaded sliders threadedly connected to the outer walls of the opposing threaded rods, a clamping block fixedly connected to the bottom of the threaded sliders, a flaring cylinder fixedly connected to the bottom of the integrated box, a flaring cone fixedly connected to the inner wall of the flaring cylinder, the flaring cone having a stepped structure, suitable for pipe diameters of 20-110mm:

[0007] The limiting assembly includes an upper hinge cylinder, which is fixedly connected to the left side of the clamping frame. The inner wall of the upper hinge cylinder is elastically connected to a limiting rod via a limiting spring. A limiting block is fixedly connected to the bottom of the limiting rod. A lower hinge cylinder is fixedly connected to the right side of the clamping frame, and a limiting groove is formed at the bottom of the lower hinge cylinder.

[0008] As a further description of the above technical solution:

[0009] A heating wire is fixedly connected to the inner wall of the flared cylinder, and a cooling pipe is connected to the inner wall of the flared cone.

[0010] As a further description of the above technical solution:

[0011] A temperature sensor is installed inside the flared cylinder, and a rubber anti-slip layer is provided on the inner arc surface of the clamping block.

[0012] As a further description of the above technical solution:

[0013] The bottom of the upper hinge cylinder is in contact with the top of the lower hinge cylinder.

[0014] As a further description of the above technical solution:

[0015] One end of the limiting spring is fixedly connected to the inner wall of the upper hinge cylinder, and the other end of the limiting spring is fixedly connected to the lower surface of the top end of the limiting rod.

[0016] As a further description of the above technical solution:

[0017] The limiting rod passes through and is slidably connected to the inner wall of the upper hinge cylinder, and the limiting rod is slidably connected to the inner wall of the lower hinge cylinder.

[0018] As a further description of the above technical solution:

[0019] The limiting block is engaged with the inner wall of the limiting groove.

[0020] As a further description of the above technical solution:

[0021] The heating wire is inserted through and fixedly connected to the bottom inner wall of the integrated box, the outer wall of the cooling pipe is inserted through and fixedly connected to the inner wall of the flared cylinder, and the bottom end of the cooling pipe is inserted through and fixedly connected to the left inner wall of the integrated box.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the angles of clamping frame one and clamping frame two can be flexibly adjusted by the limiting component. Combined with the stepped flaring cone, it can adapt to the processing needs of PE pipes of different diameters without replacing the flaring parts. This effectively avoids the downtime and parts replacement problems caused by fixed-specification flaring parts in traditional equipment, and reduces the cost of parts storage and management difficulty.

[0024] 2. In this utility model, the cooling pipe connected to the inner wall of the flared cone allows the coolant to act directly on the flared PE pipe, achieving uniform and rapid cooling and shaping. This not only avoids water waste but also prevents deformation and dimensional deviations in the flared pipe section due to uneven cooling. It can effectively prevent the flared pipe from shrinking with temperature changes, ensuring the dimensional stability of the flared part of the PE pipe and improving product quality.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a PE pipe flaring device for convenient feeding, comprising an integrated box 1. The integrated box 1 is used to integrate the electric actuator 2 and additional equipment required for heating wire 16 and cooling pipe 17. The electric actuator 2 is fixedly connected to the inner wall of the integrated box 1. The electric actuator 2 serves as a power component, which can drive clamping frame 3 and clamping frame 4 to move laterally in a stable manner. The output end of the electric actuator 2 is fixedly connected to clamping frame 3. Clamping frame 4 is connected to the right side of clamping frame 3 through a limiting component. Clamping frame 3 and clamping frame 4 can be moved laterally through the limiting component. The 0-270° angle adjustment and the setting of the limiting component allow for a flexible yet relatively stable positional relationship between clamping frame 3 and clamping frame 4, facilitating appropriate adjustments based on the PE pipe size. Both clamping frames 3 and 4 have opposing threaded rods 5 rotatably connected to their inner walls. The rotation of the opposing threaded rods 5 drives the threaded sliders 6, thereby causing the two sets of clamping blocks 7 to move synchronously in opposite directions, thus clamping the PE pipe. The outer walls of the opposing threaded rods 5 are threadedly connected to threaded sliders 6, which convert the rotational motion of the threaded rods into sliding motion. The linear motion of the block ensures the smoothness and accuracy of the slider's movement. A clamping block 7 is fixedly connected to the bottom of the threaded slider 6, allowing direct contact with the PE pipe. This fixed connection ensures that the clamping block 7 moves synchronously with the slider, reliably clamping the PE pipe. A flared cylinder 8 is fixedly connected to the bottom of the integrated box 1, providing working space for flaring the PE pipe. This fixed connection ensures stability during the flaring process, preventing displacement. A flaring cone 9 is fixedly connected to the inner wall of the flaring cylinder 8. The flaring cone 9 has a stepped structure, adaptable to pipe diameters of 2... The 0-110mm flaring cone 9 is a key component for flaring PE pipes. Its stepped shape allows it to flare PE pipes of different diameters. For PE pipes of different diameters in the same batch, there is no need to disassemble the clamping frame or replace the flaring components. Flaring can be completed by simply adjusting the clamping distance of the clamping frame and working with the stepped flaring cone 9. This greatly shortens the changeover time and improves work efficiency. The threaded slider 6 is slidably connected to the inner wall of the clamping frame 3. A temperature sensor is installed inside the flaring cylinder 8, and a rubber anti-slip layer is provided on the inner arc surface of the clamping block 7.

[0034] Reference Figures 2-4The limiting assembly includes an upper hinge cylinder 10, which is an important component of the limiting assembly and provides installation space for internal components. The upper hinge cylinder 10 is fixedly connected to the left side of the clamping frame 4. The inner wall of the upper hinge cylinder 10 is elastically connected to the limiting rod 12 through the limiting spring 11. The elastic force of the limiting spring 11 can provide the reset force for the limiting rod 12, so that the limiting rod 12 maintains a specific position when there is no external force. When it is necessary to clamp the irregular PE pipe, it is only necessary to press the limiting rod 12, compress the limiting spring 11 and drive the limiting block 13 to disengage from the limiting groove 15 of the lower hinge cylinder 14, so that the clamping frame 4 can rotate freely. The bottom of the lower hinge cylinder 14 has multiple sets of limiting grooves 15 centered on itself, supporting the fixing of clamping frame 3 and clamping frame 4 at multiple angles within the range of 0° to 270°, ensuring adaptability to PE pipes with different bending shapes and irregular cross-sections. The bottom of the limiting rod 12 is fixedly connected to a limiting block 13, which is the key part to realize the limiting function. The fixed connection ensures that it can move together with the limiting rod 12 and is used to lock the angle of the two sets of clamping frames by engaging the limiting grooves 15. The lower hinge cylinder 14 is fixedly connected to the right side of clamping frame 3. The lower hinge cylinder 14 and the upper hinge cylinder 10 cooperate with each other to form the main structure of the limiting component. The bottom of the lower hinge cylinder 14 has multiple limiting grooves 15. The positioning groove 15 and the limiting groove 15 are arranged with several sets of limiting blocks 13 at the center of the lower hinge cylinder 14. The limiting blocks 13 are used to change the angle of the two sets of clamping frames. The bottom of the upper hinge cylinder 10 is in contact with the top of the lower hinge cylinder 14. One end of the limiting spring 11 is fixedly connected to the inner wall of the upper hinge cylinder 10, and the other end of the limiting spring 11 is fixedly connected to the lower surface of the top end of the limiting rod 12. The fixed connection at both ends allows the limiting spring 11 to stably apply elastic force to the limiting rod 12. The limiting rod 12 passes through and is slidably connected to the inner wall of the upper hinge cylinder 10. The limiting rod 12 is slidably connected to the inner wall of the lower hinge cylinder 14. The limiting block 13 is engaged with the inner wall of the limiting groove 15.

[0035] Reference Figures 3-5 A heating wire 16 is fixedly connected to the inner wall of the flared cylinder 8. The heating wire 16 is externally connected to the equipment inside the integrated box 1. The heating wire 16 is made of nickel-chromium alloy, the spacing of the spiral pipe is 5cm, the rated power is 2000W, and the temperature control range is 80-120℃. The heating wire 16 can generate heat to heat the end of the PE pipe, making it soft and easy to flare. A cooling pipe 17 is connected to the inner wall of the flared cone 9. The cooling pipe 17 is made of copper coil with a diameter of φ8mm. It passes through the inner wall of the flared cone 9 and is connected to the coolant storage tank inside the integrated box 1 through a quick connector. The flow rate is controlled by a solenoid valve, which enables the coolant in the cooling pipe 17 to cool and shape the flared PE pipe. The heating wire 16 passes through and is fixedly connected to the bottom inner wall of the integrated box 1. The outer wall of the cooling pipe 17 passes through and is fixedly connected to the inner wall of the flared cylinder 8. The bottom end of the cooling pipe 17 passes through and is fixedly connected to the left inner wall of the integrated box 1.

[0036] Working principle: When it is necessary to clamp irregular PE pipes, press the limiting rod 12 to compress the limiting spring 11 and drive the limiting block 13 to disengage from the corresponding limiting groove 15 on the lower hinge cylinder 14. At this time, the clamping frame 2 4 can be rotated to adjust the clamping frame 1 3 and clamping frame 2 4 to the angle required to fit the PE pipe. Then, release the limiting rod 12, and the limiting spring 11 will reset and push the limiting rod 12 down, so that the limiting block 13 can be inserted into the corresponding limiting groove 15, thus completing the angle fixation of clamping frame 1 3 and clamping frame 2 4, which facilitates the subsequent installation of PE pipes. Next, the PE pipe is clamped. The PE pipe is placed between the clamping blocks 7 inside the clamping frame 3 and the clamping frame 4. The opposing threaded rod 5 is rotated. Since the threaded slider 6 is threadedly connected to the opposing threaded rod 5 and is slidably connected to the inner wall of the clamping frame 3 and the opposing threaded rod 5, the rotation of the opposing threaded rod 5 will drive the two sets of threaded sliders 6 to move synchronously in opposite directions, which in turn drives the clamping blocks 7 fixed at the bottom of the threaded sliders 6 to move synchronously in opposite directions until the clamping blocks 7 are tightly attached to the outer wall of the PE pipe, thus achieving stable clamping of the PE pipe.

[0037] The flaring process is then initiated. Through the control equipment inside the integrated box 1, on one hand, the electric actuator 2 is activated. The electric actuator 2 drives the clamping frame 3 and the clamping frame 4 holding the PE pipe to move laterally, pushing the end of the PE pipe into the flaring cylinder 8. On the other hand, the heating wire 16, connected to the equipment inside the integrated box 1, is activated. The heating wire 16 generates heat to heat the end of the PE pipe entering the flaring cylinder 8, softening it for subsequent flaring operations. As the electric actuator 2 continues to push, the softened end of the PE pipe gradually contacts the flaring cone 9 fixed to the inner wall of the flaring cylinder 8. The stepped structure of the flaring cone 9 compresses and flares the end of the PE pipe, forming the required flared shape.

[0038] Once the PE pipe has reached the preset shape, the heating wire 16 is turned off. Then, through the water source and control equipment inside the integrated box 1, coolant enters the cooling pipe 17 connected to the inner wall of the flaring cone 9. The coolant flows within the cooling pipe 17, rapidly cooling the flared PE pipe and setting the flared portion to prevent springback. After cooling, the electric actuator 2 reverses its operation, resetting clamping frames 3 and 4. The opposing threaded rod 5 rotates in the opposite direction, causing clamping block 7 to release the PE pipe, allowing the flared PE pipe to be removed, thus completing one PE pipe flaring operation.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
