Description

Technical Field

[0001] This invention relates to the field of hydraulic hose vulcanization technology, and more specifically, to an apparatus and process for vulcanizing hydraulic hoses. Background Technology

[0002] Hydraulic hoses, as key flexible components for transmitting pressure in hydraulic systems, are widely used in engineering machinery, mining equipment, aerospace, and transportation. Hose vulcanization is the core process that enables the internal rubber molecules to undergo cross-linking reactions, thereby achieving excellent elasticity and pressure resistance. During vulcanization, the uniformity of the temperature field, the efficiency of condensate removal at the interface between the hose and the tooling, and the thermal protection effect of the hose end joints directly determine the bonding strength, fatigue life, and appearance quality of the finished hose. As hydraulic systems develop towards higher pressure and longer lifespan, higher requirements are placed on the temperature uniformity, cleanliness, and production efficiency of hose vulcanization.

[0003] Currently, an auxiliary vulcanizing device for hydraulic hose production, with publication number CN113043507B, includes a main body comprising a base and a rotating rod. A support is mounted on the top of the base, and a crossbar is engaged on the top of the support. A fixing frame is welded to the outer side of the crossbar. An electromagnetic slide rail is installed on one side of the fixing frame, and an electromagnetic slider is slidably connected to the outer side of the electromagnetic slide rail. The device employs a multi-layered roller sleeve structure, where the hose is wound layer by layer between the rollers. The centrifugal force generated by the rotation of the rollers is used to remove condensate from the hose surface. However, in this design, the hose is wrapped layer by layer, and the water droplets on the surface of the inner hose are blocked by the outer hose. The centrifugal water removal effect decreases sharply with the increase in the number of layers, resulting in the inner hose contact surface with the roller remaining damp for a long time. After vulcanization, this area is prone to defects such as white spots and bubbles.

[0004] In addition, CN120287473A discloses an auxiliary vulcanization equipment for hydraulic hose production, which includes a vulcanization conveying fixed frame. Conveying mechanisms are installed at both ends of the top of the vulcanization conveying fixed frame, and an unwinding mechanism is provided at the top of the conveying mechanism. An installation frame is fixedly connected to the middle of the top of the vulcanization conveying fixed frame, and a dehumidification mechanism is installed at the top of another conveying mechanism. Although this solution can remove water from the surface of the hose online, it has a complex structure, many actuators, and the cleaned hose may still be contaminated with moisture again during the transfer to the vulcanization tank.

[0005] In summary, to comprehensively improve the vulcanization quality of hydraulic hoses, it is necessary to solve the problems in existing technologies, such as the failure of inner layer centrifugal drainage due to multi-layer roller obstruction, the lag in heat conduction and uneven vulcanization caused by layer wrapping, and the inability of complex dehumidification mechanisms to handle the accumulation of condensate in the shaded area of ​​the hose-tool contact surface. This will ensure that the contact surface between the hose and the tool remains dry and clean, and that each layer of hose can achieve sufficient and uniform vulcanization crosslinking. Summary of the Invention

The battery is used to provide current to the electromagnetic coil.

[0015] In a preferred embodiment, the open-loop support frame has several quick-connect interfaces, a protective cover is installed on the outside of the open-loop support frame, a quick connector is fixedly connected to the protective cover, the quick connector and the quick-connect interface are movably connected, several drainage grooves are provided on the inner wall of the protective cover, and a connection hole is provided in the center of the protective cover.

[0016] When using a process for vulcanizing hydraulic hoses according to this technical solution, an apparatus for vulcanizing hydraulic hoses as described above is employed, and the steps are as follows: S1: Mounting Preparation The open-loop support frame is placed between the active roller and the two auxiliary rollers. The auxiliary clamping assembly is controlled to drive the two auxiliary rollers to move towards each other. The linear motion assembly is used to drive the active roller to move, so that the active roller and the two auxiliary rollers clamp and fix the open-loop support frame. The clamping force is monitored in real time by the pressure sensors inside the active roller and the auxiliary rollers. S2: Loop positioning Disconnecting the battery power supply de-energizes the electromagnetic coil, generating magnetic attraction between the soft iron core and the permanent magnet, attracting the annular baffle and keeping it in one end within the annular sliding cavity, thus opening the opening of the open-ring support frame. The rotating ring is then inserted through the opening into the open-ring support frame, and finally installed between several limit wheels to complete the ring-through positioning. S3: Energized Closed Loop The battery provides current to the electromagnetic coil, which magnetizes the soft iron core and generates a magnetic force that repels the permanent magnet, pushing the annular baffle to slide in the annular cavity and closing the opening of the open-ring support frame. S4: Winding the upper tube The hydraulic hose to be vulcanized is wound in the first slot. One end of the hydraulic hose to be vulcanized is fixed at the starting point of the spiral winding groove. The feed assembly drives the threaded rod to rotate, which drives the mounting frame to move along the slide rail. At the same time, the rotating assembly drives the gear to rotate the rotating ring. Under the guidance of the auxiliary wheel and the guide wheel, the hydraulic hose in the first slot is wound layer by layer on the spiral winding groove of the open ring support frame. The rotation speed of the rotating ring is monitored in real time by the speed detector. S5: Install heat insulation baffles After the hydraulic hose is wound, install two heat insulation baffles at the beginning and end of the spiral winding groove respectively, so that both ends of the hydraulic hose are wrapped and protected inside the high-temperature resistant silicone sealing layer. S6: Unloading and Retrieving Parts Disconnect the battery power supply to reopen the opening of the open-loop support frame. Through the cooperation of the feeding component and the rotating component, the open-loop support frame with the hydraulic hose wound around it is removed from between the drive roller and the two auxiliary rollers. S7: Install protective cover By using quick couplings and quick interfaces, the protective cover is installed on the outside of the open-loop support frame, and the rotating shaft inside the external vulcanizing tank is connected to the open-loop support frame via the connecting hole. S8: Vulcanization treatment Connect the inlet and outlet ports to the external negative pressure adsorber and the external steam generator, respectively. Place the open-loop support frame with a protective cover inside the vulcanizing tank and start the vulcanizing tank to vulcanize the hydraulic hose. During the vulcanization process, the rotation speed of the open-loop support frame is set to be segmented and adjustable. During the heating stage, it rotates at a low speed and during the heat preservation stage, it rotates at a high speed. During the heat preservation stage, at certain intervals, saturated steam pulses are introduced through the negative pressure adsorption chamber through micro-pores to the contact surface between the elastic silicone pad and the hydraulic hose. The pulse intervals are maintained by the negative pressure adsorption chamber to maintain a negative pressure state and simultaneously extract condensate until vulcanization is complete.

[0017] The beneficial effects of this invention are as follows: 1. This invention uses a ring support frame as the bearing base for the hose, and the hydraulic hose is evenly wound along the spiral winding groove on the outer circumference of the ring frame. A negative pressure adsorption chamber is set inside the ring support frame, which, together with micro-pores, forms a negative pressure auxiliary drainage system. During the vulcanization process, condensate at the interface between the hose and the tooling is continuously extracted, solving the problem that water droplets in the inner layer of the multi-layer roller structure cannot be discharged. This keeps the contact surface between each layer of hose and the tooling relatively dry, effectively eliminating white spots and bubble defects in vulcanization, and significantly improving the vulcanization uniformity and surface quality of the inner and outer layers of the hose.

[0018] 2. This invention embeds a high-temperature resistant elastic silicone pad in the spiral winding groove, which provides elastic buffering for the hose under centrifugal force, preventing the hose from being deformed or indented by the edge of the winding groove during high-speed rotation. The micro-protrusion texture and groove structure on the surface of the silicone pad also store a small amount of saturated vapor, forming a micro-air cushion lubrication effect between the hose and the tooling, reducing the damage to the hose surface caused by dry friction.

[0019] 3. This invention sets the rotation speed of the open-loop support frame to be segmentally adjustable. During the heating stage, the rotation speed is low to ensure that the hose is heated evenly and to avoid excessive centrifugal force that could cause the hose to creep and extend. During the heat preservation stage, the rotation speed is switched to high speed to enhance the centrifugal drainage effect, thus achieving a balance between uniform vulcanization temperature and drainage efficiency.

[0020] 4. This invention solves the industry problem of insufficient vulcanization in the shaded area by opening through micro-pores at the bottom of the spiral winding groove and connecting the micro-pores to the built-in negative pressure adsorption chamber. During the vulcanization and heat preservation stage, saturated steam pulses are introduced into the contact surface between the rubber tube and the elastic silicone pad through the micro-pores at regular intervals to ensure that the rubber tube at the contact surface is also fully vulcanized. During the pulse interval, the system switches to a negative pressure state and simultaneously extracts condensate and residual steam in this area through the micro-pores.

[0021] 5. This invention detachably installs heat insulation baffles at the starting and ending points of the spiral winding groove of the annular support frame, and applies a high-temperature resistant silicone sealing layer to the inner side of the baffles. This not only prevents the rubber joint from scorching or aging and cracking due to overheating, but also ensures that the hose body reaches a fully vulcanized state, effectively improving the overall qualification rate and service life of the finished hose.

[0022] 6. This invention, by setting up an open-loop support frame in conjunction with an opening and closing assembly, utilizes the switching of the electromagnetic coil's on and off states to achieve rapid opening and closing of the support frame opening. This allows the rotating ring to easily enter and exit the support frame, greatly simplifying the ring-threading process before hose winding and the frame removal process after vulcanization. At the same time, the quick-connect structure with quick-connect interfaces and quick-connect couplings enables immediate disassembly and assembly of the protective cover, significantly shortening tooling preparation and disassembly time, and significantly improving the efficiency and convenience of vulcanization operations, making it suitable for mass production applications.

The battery 2201 is used to provide current to the electromagnetic coil 2203. In the power-off state, a magnetic attraction force is generated between the soft iron core 2202 and the permanent magnet 23, which attracts the annular baffle 24 and keeps it located at one end in the annular sliding cavity 1805, thereby opening the opening of the open ring support frame 18. When powered on, the battery 2201 provides current to the electromagnetic coil 2203, which magnetizes the soft iron core 2202 and generates a magnetic force that repels the permanent magnet 23, pushing the annular baffle 24 to slide and closing the opening of the open-loop support frame 18.

[0047] It should be noted that the battery 2201 is a block-shaped DC power supply component, which is fixedly installed in the mounting groove inside the cylinder wall of the open-loop support frame 18.

The electromagnetic coil 2203 is wound around its outer side. In the de-energized state, the soft iron core 2202 remains unmagnetized and generates magnetic attraction between itself and the permanent magnet 23. In the energized state, the soft iron core 2202 is magnetized by the electromagnetic coil 2203 and generates magnetic repulsion between itself and the permanent magnet 23. The electromagnetic coil 2203 is a conductive coil spirally wound around the outer side of the soft iron core 2202. Its two ends are electrically connected to the positive and negative poles of the battery 2201.

The speed detector 11 is a non-contact speed sensing element fixedly installed on the inner wall of the mounting bracket 4. Its detection end faces the end face of the rotating ring 6 and is used to detect the speed signal of the rotating ring 6 in real time and output it to the control system to realize closed-loop control of the winding speed.

[0050] Refer to the instruction manual appendix Figure 8 and Figure 10 Two heat insulation baffles 20 are detachably connected to the open-loop support frame 18. The two heat insulation baffles 20 are respectively set at the starting point and the ending point of the spiral winding groove 1801. A high-temperature resistant silicone sealing layer 21 is fixedly connected inside the heat insulation baffles 20.

[0051] It should be noted that the heat insulation baffle 20 is a plate-shaped structure. The two heat insulation baffles 20 are detachably installed at the starting point and ending point of the spiral winding groove 1801 by bolts or snap-fit ​​structures, respectively. They are used to shield and protect the two ends of the hydraulic hose after winding to prevent the high-temperature medium from directly impacting the hose end during vulcanization. The high-temperature resistant silicone sealing layer 21 is an elastic sealing gasket layer fixedly attached to the inner wall of the heat insulation baffle 20. Its shape is adapted to the inner wall shape of the heat insulation baffle 20. It is used to elastically abut against the outer wall of the end of the hydraulic hose after the heat insulation baffle 20 is installed, and plays a role in sealing and buffering protection.

[0052] Refer to the instruction manual appendix Figure 8 and Figure 11 The open-loop support frame 18 has several quick-connect interfaces 1806. A protective cover 25 is installed on the outside of the open-loop support frame 18. A quick connector 26 is fixedly connected to the protective cover 25. The quick connector 26 and the quick-connect interface 1806 are movably connected. Several drainage grooves 2501 are provided on the inner wall of the protective cover 25. A connection hole 2502 is provided in the center of the protective cover 25.

[0053] It should be noted that the quick-connect interface 1806 is a recessed snap-fit ​​interface formed on the outer wall of the open-loop support frame 18. Multiple quick-connect interfaces are evenly distributed along the outer circumference of the open-loop support frame 18, with their number and position corresponding one-to-one with the quick-connect coupling 26. It is used to cooperate with the quick-connect coupling 26 to achieve quick assembly and disassembly of the protective cover 25. The protective cover 25 is a cylindrical shell structure, its inner diameter matching the outer diameter of the open-loop support frame 18. It is fitted onto the outside of the open-loop support frame 18 and is used to handle the hydraulic hose wound on the spiral winding groove 1801 during the vulcanization process. The protective cover 2501 is a strip-shaped groove on the inner wall of the protective cover 25. There are multiple grooves that extend along the axial direction of the protective cover 25 and are evenly distributed in the circumference. It is used to guide the condensate along the inner wall of the protective cover 25 during the vulcanization process and prevent the condensate from accumulating in the protective cover 25 and affecting the vulcanization quality. The connecting hole 2502 is a circular through hole opened at the center of the protective cover 25. It is used for the rotating shaft in the external vulcanizing tank to pass through and be connected to the open ring support frame 18 for transmission.

[0054] Refer to the instruction manual appendix Figure 1 To be continued Figure 11 In this embodiment, the present invention provides a process for vulcanizing hydraulic hoses, employing an apparatus for vulcanizing hydraulic hoses as described above, comprising the following steps: S1: Mounting Preparation The open-loop support frame 18 is placed between the active roller 15 and the two auxiliary rollers 17. The auxiliary clamping assembly is controlled to drive the two auxiliary rollers 17 to move towards each other. The linear motion assembly is used to drive the active roller 15 to move, so that the active roller 15 and the two auxiliary rollers 17 clamp and fix the open-loop support frame 18. The clamping force is monitored in real time by the pressure sensors in the active roller 15 and the auxiliary rollers 17. S2: Loop positioning Disconnect the power supply of battery 2201 to de-energize electromagnetic coil 2203. Magnetic attraction is generated between soft iron core 2202 and permanent magnet 23, attracting annular baffle 24 and keeping it in one end within annular sliding cavity 1805. This opens the opening of open ring support frame 18. The rotating ring 6 is then inserted through the opening into open ring support frame 18. Finally, the rotating ring 6 is installed between several limiting wheels 5 to complete the ring-entry positioning. S3: Energized Closed Loop Battery 2201 provides current to electromagnetic coil 2203, which magnetizes soft iron core 2202 and generates a magnetic force that repels permanent magnet 23, pushing annular baffle 24 to slide in annular sliding cavity 1805, thereby closing the opening of open ring support frame 18. S4: Winding the upper tube The hydraulic hose to be vulcanized is wound in the slot 601. One end of the hydraulic hose to be vulcanized is fixed at the starting point of the spiral winding groove 1801. The threaded rod 3 is driven to rotate by the feeding component, which drives the mounting frame 4 to move along the slide rail 101. At the same time, the rotating component drives the gear 7 to rotate the rotating ring 6. Under the guidance of the auxiliary wheel 8 and the guide wheel 9, the hydraulic hose in the slot 601 is wound layer by layer on the spiral winding groove 1801 of the open ring support frame 18. The rotation speed of the rotating ring 6 is monitored in real time by the speed detector 11. S5: Install heat insulation baffles After the hydraulic hose is wound, two heat insulation baffles 20 are installed at the starting point and the ending point of the spiral winding groove 1801, respectively, so that both ends of the hydraulic hose are wrapped and protected inside the high-temperature resistant silicone sealing layer 21. S6: Unloading and Retrieving Parts Disconnect the power supply to the battery 2201 so that the opening of the open-loop support frame 18 is opened again. Through the cooperation of the feeding component and the rotating component, the open-loop support frame 18 with the hydraulic hose wound around it is taken out from between the active roller 15 and the two auxiliary rollers 17. S7: Install protective cover By using quick connector 26 and quick interface 1806, the protective cover 25 is installed on the outside of the open ring support frame 18, and the rotating shaft inside the external vulcanizing tank is connected to the open ring support frame 18 via the connection hole 2502. S8: Vulcanization treatment Connect the inlet and outlet ports 1804 to the external negative pressure adsorber and the external steam generator, respectively. Place the open-loop support frame 18 with the protective cover 25 inside the vulcanizing tank. Start the vulcanizing tank to vulcanize the hydraulic hose. During the vulcanization process, the rotation speed of the open-loop support frame 18 is set to be segmented and adjustable. During the heating stage, it rotates at a low speed and during the heat preservation stage, it rotates at a high speed. During the heat preservation stage, at certain intervals, saturated steam pulses are introduced through the negative pressure adsorption chamber 1802 and the contact surface between the elastic silicone pad 19 and the hydraulic hose through the micro-pores 1803. The pulse intervals are maintained under negative pressure through the negative pressure adsorption chamber 1802, and condensate is simultaneously extracted until vulcanization is complete.

[0055] It should be noted that in the mounting preparation step, the active roller 15 and the two auxiliary rollers 17 are arranged in a triangle, and the three together form a three-point clamping and positioning system. The active roller 15, as the active driving roller, rotates around its own axis under the drive of the servo motor 14. The two auxiliary rollers 17, as the driven support rollers, passively rotate with the rotation of the open-loop support frame 18. The pressure sensor detects the contact pressure value between each roller and the outer wall of the open-loop support frame 18 in real time and feeds it back to the control system. The control system adjusts the driving force of the auxiliary clamping component and the linear motion component according to the feedback value to keep the clamping force within the preset threshold range, ensuring that the open-loop support frame 18 does not experience axial movement or radial jump during rotation, while avoiding excessive clamping force that could cause elastic deformation of the open-loop support frame 18. In the ring-pinning positioning step, after the battery 2201 is de-energized, the electromagnetic coil 2203 loses power and demagnetizes, and the soft iron core 2202 is in an unmagnetized state. The magnetic field of the permanent magnet 23 magnetizes the soft iron core 2202 and generates a magnetic attraction force. Under the action of this magnetic attraction force, the annular baffle 24 is attracted to one end of the annular sliding cavity 1805 near the opening and closing assembly, so that the opening of the open ring support frame 18 is kept open. At this time, the rotating ring 6 can pass through the opening without obstruction into the internal cavity of the open ring support frame 18. After the rotating ring 6 is inserted into place, it is embedded between the four limiting wheels 5. The four limiting wheels 5 simultaneously apply radial constraints to the outer circumferential wall of the rotating ring 6 so that it cannot be displaced in the radial direction. In the closed-loop power-on step, when the DC current output by the battery 2201 flows through the electromagnetic coil 2203, the electromagnetic coil 2203 generates an electromagnetic field and magnetizes the soft iron core 2202. The magnetic pole direction of the magnetized soft iron core 2202 is the same as the magnetic pole direction of the permanent magnet 23 towards one end of the soft iron core 2202. The two generate a magnetic repulsion force. Under the push of this magnetic repulsion force, the annular baffle 24 slides along the annular slide cavity 1805 to the other end, so that the opening of the open-loop support frame 18 gradually narrows until it is completely closed. At this time, the open-loop support frame 18 forms a complete annular closed structure, which facilitates the continuous routing of the hydraulic hose along the spiral winding groove 1801 during subsequent winding operations without it coming off or getting stuck at the opening. In the winding process, the hydraulic hose to be vulcanized is pre-wound into the slot 601 to form a hose reserve. One end of the hose is led out from the slot 601 and passes sequentially around the auxiliary wheel 8 and the guide wheel 9. After reversing direction through the annular guide groove of the auxiliary wheel 8 and the annular guide groove of the guide wheel 9, it extends to the starting point of the spiral winding groove 1801 and is fixed. The feeding assembly drives the threaded rod 3 to rotate through the synchronous belt drive. The threaded rod 3 drives the mounting bracket 4 to move linearly along the slide rail 101 at a uniform speed through the threaded drive. At the same time, the rotating assembly drives the rotating ring 6 to rotate at a uniform speed through the meshing transmission of gear 1002 and gear 7. The linear movement speed of mounting bracket 4 and the rotation speed of rotating ring 6 are controlled by the control system to maintain a fixed transmission ratio between them. This allows the hose leading out of slot 601 to be wound smoothly and layer by layer into spiral winding groove 1801 with a constant pitch. During the winding process, auxiliary wheel 8 and guide wheel 9 continuously apply tension to the hose to keep it taut. Speed ​​detector 11 collects the speed signal of rotating ring 6 in real time and transmits it to the control system. The control system dynamically adjusts the speed of servo motor 201 and servo motor 1001 according to the speed feedback value to maintain the set speed constant. During the installation of the heat insulation baffles, after the hydraulic hose is completely wound into the spiral winding groove 1801, the starting end and the ending end of the hose are located at the starting position and the ending position of the spiral winding groove 1801, respectively. The two heat insulation baffles 20 are aligned with the starting position and the ending position, respectively, and fixed to the open ring support frame 18 by bolts or buckles. The high-temperature resistant silicone sealing layer 21 on the inner side of the heat insulation baffle 20 is compressed and elastically deformed during the locking process of the heat insulation baffle 20. The deformed high-temperature resistant silicone sealing layer 21 is tightly attached to the outer wall of the hose end and the side wall of the spiral winding groove 1801, forming a circumferential sealing strip, which effectively prevents the high-temperature medium in the vulcanizing tank from directly scouring the exposed part of the hose end. During the unloading and removal process, the battery 2201 is de-energized again, causing the electromagnetic coil 2203 to demagnetize. The soft iron core 2202 and the permanent magnet 23 generate magnetic attraction to the annular baffle 24, causing the opening of the open ring support frame 18 to open for the second time. At this time, the feeding component drives the mounting frame 4 to move the rotating ring 6 in the opposite direction along the slide rail 101, causing the rotating ring 6 to exit from the opening and exit the internal cavity of the open ring support frame 18. At the same time, the auxiliary clamping component drives the two auxiliary rollers 17 to move in opposite directions, causing the active roller 15 and the auxiliary roller 17 to release the clamping force on the open ring support frame 18 synchronously. The operator removes the open ring support frame 18 with the rubber tube wrapped around it from the clamping position. During the installation of the protective cover, the protective cover 25 is fitted onto the outer side of the open-loop support frame 18 along its axial direction. After the cover is in place, each quick connector 26 is aligned with the corresponding quick interface 1806 and snapped into place, thereby achieving a quick and fixed connection between the protective cover 25 and the open-loop support frame 18. The connection hole 2502 is located on the central axis of the protective cover 25 and penetrates through the end wall of the protective cover 25. After the rotating shaft of the external vulcanizing tank passes through the connection hole 2502, it forms a key connection with the inner wall or end face keyway of the open-loop support frame 18, so that the rotational power of the vulcanizing tank rotating shaft is transmitted to the open-loop support frame 18 through the protective cover 25 to drive the two to rotate synchronously. During the vulcanization process, saturated steam generated by an external steam generator enters the negative pressure adsorption chamber 1802 through the inlet / outlet port 1804, and is then sprayed out from the negative pressure adsorption chamber 1802 through various micro-pores 1803 to the contact interface between the elastic silicone pad 19 and the hydraulic hose. The external negative pressure adsorber draws in the negative pressure adsorption chamber 1802 through the inlet / outlet port 1804 and establishes a negative pressure environment. The condensate at the contact interface is drawn back into the negative pressure adsorption chamber 1802 through the micro-pores 1803 and then discharged through the inlet / outlet port 1804. During the heating stage, the open-loop support frame 18 rotates at a low speed to ensure that the hose is heated evenly. During the heat preservation stage, the open-loop support frame 18 rotates at a high speed to accelerate the discharge of condensate along the drain trough 2501 using centrifugal force. Throughout the vulcanization process, the control system cyclically executes the operation of introducing saturated steam pulses and maintaining negative pressure suction according to the preset time intervals until the vulcanization timer ends.

[0056] It is worth noting that the vulcanizing tank is a closed pressure vessel used for vulcanizing rubber products in the prior art. It has an internal rotating shaft that can rotate around its own axis. The rotating shaft is driven by a drive motor independently installed outside the tank body via a reduction transmission mechanism. One end of the rotating shaft extends into the tank body and is equipped with a keyway or flange connection structure to form a transmission fit with the connection hole 2502 of the open-loop support frame 18. The vulcanizing tank is also equipped with a heating device and a temperature control system to raise the temperature inside the tank and maintain it within the temperature range required for the vulcanization process. The vulcanizing tank is also equipped with a pressure control system to fill the tank with pressurizing medium to establish the pressure environment required for vulcanization. In the S8 vulcanization process, the open-loop support frame 18, equipped with a protective cover 25, is hoisted or sent into the vulcanizing tank as a whole. Then, the rotating shaft is connected to the connection hole 2502 of the open-loop support frame 18 to complete the transmission docking. The tank door of the vulcanizing tank is closed and the tank body is sealed. The heating device is started to raise the temperature inside the tank to the vulcanizing temperature according to the preset heating curve. At the same time, the drive motor of the rotating shaft is started to make the open-loop support frame 18 rotate continuously inside the tank. During the heating stage, the rotating shaft rotates at a low speed. During the heat preservation stage, the rotating shaft switches to high speed. During the vulcanization process, the inlet and outlet ports 1804 are switched to connect with the external negative pressure adsorber and the external steam generator in sequence (pipeline connection is made in advance, and valves are used for switching later). Saturated steam pulse injection and negative pressure suction are performed in the high temperature and high pressure environment inside the tank until the vulcanization process is completed. Heating is stopped and the temperature and pressure are reduced. The tank door is opened and the open-loop support frame 18 and the protective cover 25 are taken out together.

[0057] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.

The clamping force is monitored in real time by the pressure sensors in the active roller (15) and the auxiliary rollers (17). S2: Loop positioning Disconnect the power supply of the battery (2201) to de-energize the electromagnetic coil (2203). A magnetic attraction force is generated between the soft iron core (2202) and the permanent magnet (23), attracting the annular baffle (24) to keep it in one end within the annular sliding cavity (1805). This opens the opening of the open ring support frame (18). The rotating ring (6) is then inserted through the opening into the open ring support frame (18). The rotating ring (6) is then installed between several limiting wheels (5) to complete the ring-penetrating positioning. S3: Energized Closed Loop The battery (2201) provides current to the electromagnetic coil (2203), which magnetizes the soft iron core (2202) and generates a magnetic force that repels the permanent magnet (23), pushing the annular baffle (24) to slide in the annular sliding cavity (1805) and closing the opening of the open ring support frame (18); S4: Winding the upper tube The hydraulic hose to be vulcanized is wound in the slot 1 (601). One end of the hydraulic hose to be vulcanized is fixed at the starting point of the spiral winding groove (1801). The threaded rod (3) is driven to rotate by the feeding component, which drives the mounting frame 1 (4) to move along the slide rail (101). At the same time, the rotating component drives the gear 1 (7) to drive the rotating ring (6) to rotate. Under the guidance of the auxiliary wheel (8) and the guide wheel (9), the hydraulic hose in the slot 1 (601) is wound layer by layer on the spiral winding groove (1801) of the open ring support frame (18). The rotation speed of the rotating ring (6) is monitored in real time by the speed detector (11). S5: Install heat insulation baffles After the hydraulic hose is wound, two heat insulation baffles (20) are installed at the starting point and the ending point of the spiral winding groove (1801) respectively, so that the two ends of the hydraulic hose are wrapped and protected inside the high temperature resistant silicone sealing layer (21). S6: Unloading and Retrieving Parts Disconnect the power supply of the battery (2201) so that the opening of the open ring support frame (18) is opened again. Through the cooperation of the feeding component and the rotating component, the open ring support frame (18) with the hydraulic hose wound around it is taken out from between the active roller (15) and the two auxiliary rollers (17). S7: Install protective cover By using the quick connector (26) and quick interface (1806), the protective cover (25) is installed on the outside of the open ring support frame (18), and the rotating shaft inside the external vulcanizing tank is connected to the open ring support frame (18) via the connection hole (2502). S8: Vulcanization treatment Connect the inlet and outlet ports (1804) to the external negative pressure adsorber and the external steam generator respectively. Place the open-loop support frame (18) with the protective cover (25) inside the vulcanizing tank. Start the vulcanizing tank to vulcanize the hydraulic hose. During the vulcanization process, the rotation speed of the open-loop support frame (18) is set to be segmented and adjustable. During the heating stage, it rotates at a low speed and during the heat preservation stage, it rotates at a high speed. During the heat preservation stage, at certain intervals, saturated steam pulses are introduced into the contact surface between the elastic silicone pad (19) and the hydraulic hose through the micro-pores (1803) of the negative pressure adsorption chamber (1802). The pulse gaps are maintained in a negative pressure state through the negative pressure adsorption chamber (1802) and the condensate is extracted simultaneously until the vulcanization is completed.
