Description

Technical Field

[0001] This invention relates to the field of hose production equipment technology, specifically to a non-destructive intelligent core removal device for brake hoses. Background Technology

[0002] Brake hose core removal equipment is a key piece of equipment in hose production and processing. It is mainly used in the post-processing stage of various hollow hoses such as rubber hoses and silicone hoses. Its core function is to separate and extract the core, which supports the shape of the inner wall during the hose molding and curing process, from the inside of the hose to form a hollow channel that meets the usage requirements. This ensures the hose can carry media and protect the basic functions of internal components. It is widely applicable to various hose production scenarios in industry, automotive, and medical fields.

[0003] Early hose core removal equipment consisted mostly of simple clamping components and manual or single-power pushing mechanisms. It relied on manual positioning of the hose and application of pushing force to remove the core, which resulted in low core removal efficiency and high labor intensity. Furthermore, uneven manual force application could easily lead to hose tearing and inner wall scratches. When the core adhered to the inner wall of the hose, it could also cause jamming. To solve these problems, existing core removal equipment has gradually integrated a power drive mechanism, a water lubrication system, and positioning clamps. It provides continuous pushing force through a power source and reduces core removal resistance with the help of water flow lubrication, thereby improving core removal stability and efficiency to a certain extent.

[0004] However, existing equipment still has significant limitations: the initial pressing and core removal process of existing equipment uses a fixed thrust output or a single water injection mode, lacking an adaptive buffer structure for the high resistance in the early stage of core removal. This causes the power source to directly bear the instantaneous peak resistance, which will cause wear and damage to the water pump and hydraulic rod components. At the same time, the water injection path of existing equipment is mostly a single channel, and the water flow is difficult to evenly cover the contact area between the core and the inner wall of the hose. There is still a problem of excessive local resistance in the early stage of core removal. In addition, the linkage and coordination between hose fixing and power pushing is insufficient, which will aggravate core removal damage due to positioning deviation. It cannot well adapt to the core removal needs of ultra-long hoses or hoses with high adhesion. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a non-destructive intelligent core removal device for brake hoses, which solves the problems of lack of a high-resistance adaptive buffer structure, single water injection path, and insufficient coordination between hose fixing and power pushing in the initial stamping core removal process.

Multiple expanding rubber balls are arranged inside the outer casing of the equipment, and a central skeleton ball is fixedly connected inside each expanding rubber ball.

[0010] Preferably, the engaging connection assembly includes multiple engaging frame blocks, which are fixedly connected to the front side of the outer casing of the equipment.

[0016] This invention provides a non-destructive intelligent core-removal device for brake hoses. It has the following beneficial effects:

[0017] 1. This invention connects an external water supply pipe to a main water valve, injects water into a storage tank, places a cylindrical block into a locking frame block, rotates a limiting ring and fixes it with a squeezing block, inserts a rubber tube, and activates a pressing cylinder to make the conical squeezing hole block fit with the conical groove to fix the rubber tube. Pulling the hole pressing rod adjusts the piston position and fixes it with connecting bolts. Water from the storage tank enters the pressing cylinder through a one-way inlet valve and a corrugated pipe. Activating the hydraulic rod pushes the piston down, and water is injected into the rubber tube through a connecting pipe, a one-way valve, a connecting water pipe, and a spiral outlet. When the piston resets, the storage tank automatically replenishes water. Repeating this operation completes the initial pressing and core removal.

[0018] 2. In this invention, when the infrared sensor fails to detect the indicator sign, the hydraulic rod stops after being pressed to the lowest position. Then, the electromagnetic valve opens, and the high-pressure water pump is started to draw water from the water storage tank. The water flows through the diversion pipe, branch pipe, and three-way valve into the connecting pipe, and then through the connecting water pipe and the conical extrusion hole block into the hose. Finally, the high-pressure water pump continuously supplies water to push the tube core to complete the rapid core removal.

[0019] 3. In this invention, the pressing cylinder is activated to cause the conical extrusion hole block to shrink. After the expansion rubber ball is inserted, the pressing cylinder is activated again to fix the rubber tube. Then, the air pump and heating wire are activated. The gas is heated through the air supply pipe and the air passage pipe, and then enters the rubber tube through the telescopic hose, the one-way air inlet pipe and the spiral outlet. This pushes the expansion rubber ball to move and clean up water stains. After the expansion rubber ball is discharged, the hot air flows spirally in the rubber tube through the spiral outlet to complete the drying operation. Attached Figure Description

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see the appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 and attached Figure 10 This invention provides a non-destructive intelligent core removal device for brake hoses, including an outer casing 1. Multiple pressing cylinders 5 are fixedly connected to the inner side of the outer casing 1. A conical extrusion hole block 7 is fixedly connected to the other end of each pressing cylinder 5. A main water valve 6 is fixedly connected to the rear side of the outer casing 1. A water storage tank 8 is connected to the front end of the main water valve 6. A preliminary pressing core removal mechanism 2 is provided inside the outer casing 1 for injecting water during the initial core removal process. A quick-release switching mechanism 3 is provided inside the outer casing 1 for switching the water injection device after the resistance decreases. A cleaning and drying mechanism 4 is provided inside the outer casing 1 for cleaning water stains and drying the hose after core removal. Multiple engaging connection components 9 are provided on the front side of the outer casing 1 for quickly fixing the hose to the device.

[0032] The initial stamping core removal mechanism 2 includes multiple pressing cylinders 21. The outer sides of each pressing cylinder 21 are fixedly connected to the rear side of the equipment outer casing 1. A hydraulic rod 22 is fixedly connected to the inner side of the equipment outer casing 1. A horizontal plate 23 is fixedly connected to the other end of the hydraulic rod 22. A piston 26 is slidably connected to the inner side of each pressing cylinder 21. A limiting rod 27 is fixedly connected to the top of the piston 26. A perforated pressing rod 24 is slidably connected to the outer wall of the limiting rod 27. A buffer spring 25 is fixedly connected to the bottom end of the perforated pressing rod 24. The other end of the buffer spring 25... The end is fixedly connected to the outside of the piston 26. The inner side of the horizontal plate 23 is threaded with a connecting bolt 213. The outer side of the connecting bolt 213 engages with the inner side of the corresponding hole pressing rod 24. The outer side of the pressing cylinder 21 is connected to a connecting pipe 210. The other end of the connecting pipe 210 is connected to a connecting water pipe 212. The other end of the connecting water pipe 212 is connected to the outer side of the conical extrusion hole block 7. A one-way valve 211 is fixedly connected to the outer wall of the connecting pipe 210. Multiple spiral discharge ports 214 are opened on the outer side of the conical extrusion hole block 7.

[0033] The outer wall of the water storage tank 8 is connected to multiple corrugated pipes 28. A one-way water inlet valve 29 is fixedly connected to the outer wall of the corrugated pipe 28. The other end of the corrugated pipe 28 is connected to the top of the piston 26. The hole pressing rod 24 passes through the horizontal plate 23 in the vertical direction. The connecting bolt 213 is horizontally inserted into the horizontal plate 23 and threadedly connected to the hole pressing rod 24.

[0034] The engaging connection assembly 9 includes multiple engaging frame blocks 91, which are fixedly connected to the front side of the outer casing 1 of the equipment. A cylindrical block 92 is provided on the inner side of the engaging frame block 91, and a conical groove 93 is provided on the rear side of the cylindrical block 92. The conical groove 93 engages with the conical extrusion hole block 7. An anti-slip ring 94 is fixedly connected to the inner side of the engaging frame block 91, and a limiting ring 95 is rotatably connected to the inner side of the engaging frame block 91. An extrusion block 96 is rotatably connected to the outer wall of the engaging frame block 91.

[0035] Specifically, the main water valve 6 connects to the external water supply pipe, and external water enters the water storage tank 8 through the main water valve 6. Simultaneously, a cylindrical block 92 of the corresponding size is placed in the locking frame block 91. Then, the limiting ring 95 is rotated to lock the cylindrical block 92 onto the locking frame block 91. Subsequently, the squeezing block 96 locks the limiting ring 95 above the cylindrical block 92. At this point, the hose to be removed is inserted into the front of the cylindrical block 92. Since the hose is quite long, to facilitate the removal process, multiple hose-removing and straightening fixtures are used on the second floor. These fixtures consist of a support frame and multiple rollers, arranging the hose neatly in a circular motion. When processing the hose, it is in a freely straightened state. The straightening and aligning fixture uses a passive guide wheel structure made entirely of 304 stainless steel. This prevents friction-induced heat generation and contamination of the hose during the traction and winding process. Then, the pressing cylinder 5 is activated, pushing the conical extrusion hole block 7 to the rear of the cylindrical block 92. The outer side of the conical extrusion hole block 7 fits against the conical groove 93 on the rear side of the cylindrical block 92, squeezing and clamping the inserted hose to achieve fixation. Then, depending on the required hose length, the hole pressing rod 24 is pulled upwards, adjusting the position of the piston 26 in the pressing cylinder 21. Finally, the connecting bolt 213 is rotated to connect the hole pressing rod 24 to the horizontal plate 23. During the upward movement of the hole pressing rod 24, the water in the storage tank 8... Water enters the bellows 28 through the one-way inlet valve 29. Under the negative pressure generated when the piston 26 moves upward, the water in the bellows 28 enters the pressing cylinder 21. By activating the hydraulic rod 22, the piston 26 is pushed downward. In the early stage of downward movement, the piston 26 squeezes the water in the pressing cylinder 21, sending the water into the connecting pipe 210. After passing through the one-way valve 211, the water enters the connecting water pipe 212. Subsequently, the water enters the spiral discharge port 214 through the cavity in the conical extrusion hole block 7 and then into the clamped rubber tube. When the water fills the cavity at this end, the hydraulic rod 22 continues to move downward. Due to the friction between the rubber tube and the inner tube core, resistance is created to the injected water. Since the resistance is greater than the buffer spring... Driven by the hydraulic rod 22, the spring 25 is compressed until the hole pressing rod 24 contacts the piston 26. Then, the driving force of the hydraulic rod 22 acts directly on the piston 26, making the injected pressure greater than the resistance, allowing the remaining water to be injected into the hose, completing the initial water injection. When the piston 26 moves to the lowest position, the hydraulic rod 22 extends, driving the piston 26 to reset. Due to the one-way flow performance of the one-way valve 211 in the connecting pipe 210, the water in the water tank 8 is drawn into the pressing cylinder 21 by the negative pressure suction generated inside the pressing cylinder 21, guided by the bellows 28 and the one-way inlet valve 29, completing the automatic water replenishment operation.

[0036] See appendix Figure 4 Appendix Figure 5 and attached Figure 8The quick-release switching mechanism 3 includes a high-pressure water pump 31, which is fixedly connected to the inside of the outer casing 1 of the equipment. One end of the high-pressure water pump 31 is connected to the outside of the water storage tank 8, and the other end of the high-pressure water pump 31 is connected to a diversion pipe 32. Multiple branch pipes 33 are connected to the outer wall of the diversion pipe 32. A three-way valve 35 is connected to the end of the branch pipe 33 away from the diversion pipe 32. The inner side of the three-way valve 35 is connected to the middle of the connecting pipe 210. An electromagnetic valve 34 is fixedly connected to the middle of the branch pipe 33. An infrared sensor 36 is fixedly connected to the top of the limiting rod 27. An indicator 37 is fixedly connected to the outer wall of the hole pressing rod 24.

[0037] Infrared sensor 36 and indicator 37 are arranged opposite each other in the vertical direction, and three-way valve 35 forms a three-way structure with connecting pipe 210 and branch pipe 33 respectively;

[0038] Specifically, after repeated water injection operations, the frictional resistance between the hose and the inner core gradually decreases, and the elastic potential energy of the buffer spring 25 gradually overcomes this resistance. At this time, the infrared sensor 36 located at the top of the limiting rod 27 no longer moves upward due to the subsequent contraction of the buffer spring 25. At this time, the infrared sensor 36 cannot sense the indicator 37. After the hydraulic rod 22 completes the pressing at the lowest point, it stops starting and controls the opening of the solenoid valve 34 above the branch pipe 33. At the same time, the high-pressure water pump 31 is started, so that the water in the water tank 8 is pumped out and sent into the diversion pipe 32. Then, it enters the connecting pipe 210 through the branch pipe 33 and the three-way valve 35, and then enters the hose through the connecting water pipe 212 and the conical extrusion hole block 7. Since the frictional resistance is low at this time, the pressure delivered by the high-pressure water pump 31 is sufficient to overcome this frictional resistance, and the high-pressure water pump 31 quickly performs the subsequent core removal operation.

[0039] See appendix Figure 4 Appendix Figure 5 Appendix Figure 8 and attached Figure 9 The cleaning and drying mechanism 4 includes an air pump 41, which is fixedly connected to the inside of the outer casing 1 of the equipment. The other end of the air pump 41 is connected to an air supply pipe 42. The end of the air supply pipe 42 away from the air pump 41 is connected to a ventilation pipe 43. The outer side of the ventilation pipe 43 is fixedly connected to the inside of the outer casing 1 of the equipment. The other end of the air supply pipe 42 is connected to the outer side of the ventilation pipe 43. A heating wire 44 is fixedly connected to the inner side of the ventilation pipe 43. Multiple telescopic hoses 45 are connected to the outer wall of the ventilation pipe 43. The other end of the telescopic hoses 45 is connected to a one-way air inlet pipe 46. The end of the one-way air inlet pipe 46 away from the telescopic hoses 45 is connected to a conical extrusion hole block 7. Multiple expansion rubber balls 48 are provided inside the outer casing 1 of the equipment. A central skeleton ball 47 is fixedly connected inside the expansion rubber balls 48.

[0040] One end of the one-way air intake pipe 46 is connected to the telescopic hose 45, and the other end is connected to the inside of the conical extrusion hole block 7. The spiral outlet 214 corresponds to the output end of the one-way air intake pipe 46.

[0041] Specifically, after the hose is detached, the pressing cylinder 5 is activated to cause the conical extrusion hole block 7 to contract. Then, the expansion rubber ball 48 is placed in the hose. The pressing cylinder 5 is activated again to cause the conical extrusion hole block 7 to press and fix the hose. Then, the air pump 41 is activated to send external gas into the ventilation pipe 43 through the air supply pipe 42. The heating wire 44 is activated to preheat the ventilation pipe 43, so that the incoming gas is heated. Then, the gas enters the conical extrusion hole block 7 through the telescopic hose 45 and the one-way air inlet pipe 46, and enters the hose through the spiral outlet 214. This pushes the expansion rubber ball 48, which is composed of the central skeleton ball 47, to move in the hose, cleaning the residual water stains in the hose. After the expansion rubber ball 48 is discharged from the other end of the hose, the preheated airflow moves spirally in the hose through the spiral outlet 214 to dry the remaining slight water stains, preventing the residual water stains from causing damage to the hose in the later stages.

[0042] See appendix Figure 1 Appendix Figure 2 and attached Figure 3 Multiple control levers 10 are fixedly connected to the top of the outer casing 1, a water pressure gauge 11 is fixedly connected to the top of the outer casing 1, an adjustment knob 12 is fixedly connected to the top of the outer casing 1, and a storage block 13 is fixedly connected to the front side of the outer casing 1.

[0043] Specifically, the top of the equipment casing 1 integrates multiple functional control components. Multiple control levers 10 correspond to the start / stop and operation switching of the initial pressing and core removal mechanism 2, the quick-release switching mechanism 3, and the cleaning and drying mechanism 4, respectively. Operators can control the extension and retraction of the hydraulic rod 22, the start and stop of the high-pressure water pump 31, and the coordinated operation of the air pump 41 and the heating wire 44 by swinging different control levers 10. This enables independent control and coordinated operation of each mechanism. The water pressure gauge 11 fixed on the top of the equipment casing 1 is connected to the connecting pipe 210, which can monitor the pressure changes of the water flow in real time during the core removal process, and provide intuitive feedback on the buffering and adaptation effect of the initial pressing and core removal stage and the high-pressure water supply status of the quick-release switching stage. To facilitate operators' timely monitoring of equipment operating parameters and prevent hose damage or equipment malfunction due to abnormal pressure, the top-fixed adjustment knob 12 is used to adjust key operating parameters. By rotating the adjustment knob 12, the thrust of the hydraulic rod 22, the water supply pressure of the high-pressure water pump 31, and the heating temperature of the heating wire 44 can be changed, adapting to the core removal and drying needs of hoses of different specifications and materials. In addition, a storage block 13 is fixedly connected to the front of the equipment outer casing 1. The storage block 13 has multiple matching grooves inside, which can be used to store spare cylindrical blocks 92, expansion rubber balls 48 consumables, and maintenance tools. This not only avoids the loss or damage of consumables and tools, but also keeps the work site clean and orderly, improving operational convenience.

[0044] Working principle: First, the external water supply pipe is sealed and connected to the main water valve 6. After the main water valve 6 is opened, the external water source is stably injected into the water storage tank 8 to complete the storage of water for core removal. Then, the cylindrical block 92, which is compatible with the specifications of the hose to be removed, is placed in the locking frame block 91. The limiting ring 95 is rotated to make it fit the outside of the cylindrical block 92. Then, the limiting ring 95 is locked and fixed by rotating the squeezing block 96 to ensure that the cylindrical block 92 does not shift during the operation. One end of the hose to be removed is inserted into the matching interface on the front side of the cylindrical block 92. The pressing cylinder 5 is activated. The telescopic end of the pressing cylinder 5 pushes the conical squeezing hole block 7 towards the cylindrical block 92 until the outside of the conical squeezing hole block 7 is completely fitted with the conical groove 93 on the rear side of the cylindrical block 92. Through the squeezing action of the conical surface, To achieve a sealed clamping of the hose end and prevent leakage or hose displacement during water injection, the hole pressing rod 24 is manually pulled vertically up and down according to the length of the hose to be removed and the removal requirements. This moves the piston 26 to the appropriate initial position within the pressing cylinder 21. Then, the connecting bolt 213 is rotated to securely lock the hole pressing rod 24 to the horizontal plate 23, ensuring stable power transmission. During the process of the hole pressing rod 24 moving upward and causing the piston 26 to reset, a negative pressure is formed inside the pressing cylinder 21. Under the suction of the negative pressure, water in the water tank 8 enters the bellows 28 through the one-way inlet valve 29 and further flows into the pressing cylinder 21 to complete the water replenishment. The hydraulic rod 22 is then activated, and its telescopic end pushes the horizontal plate 23 and the hole pressing rod 24 downward simultaneously. The orifice pressing rod 24 transmits thrust through the limiting rod 27. At this time, the buffer spring 25 is in its natural state. When the water in the pressing cylinder 21 is squeezed by the piston 26, it is transported to the internal cavity of the conical extrusion orifice block 7 through the connecting pipe 210, one-way valve 211, and connecting water pipe 212. The water is then injected into the gap between the hose and the core through the spiral discharge port 214 on the conical extrusion orifice block 7. In the initial stage of core removal, the hose and the core are in close contact and the frictional resistance is large. When the pressure of the injected water flow is insufficient to push the core, the continuous thrust of the hydraulic rod 22 will cause the buffer spring 25 to gradually compress. The peak resistance is absorbed by the elastic deformation of the spring, preventing the hydraulic rod 22 and the power source of the subsequent high-pressure water pump 31 from directly bearing the ultimate pressure. At the same time, the spiral discharge port 214 sprays out spiral water. The uniform water flow evenly covers the outer wall of the tube core, forming a complete water film and effectively reducing local frictional resistance. When the elastic potential energy of the buffer spring 25 and the water pressure exceed the core removal resistance, the tube core begins to move slightly. The piston 26 continues to move downwards until it reaches the lowest position. Subsequently, the hydraulic rod 22 extends in the opposite direction, driving the piston 26 to move upwards and reset. Due to the one-way valve 211 on the connecting pipe 210 restricting the backflow of water, a negative pressure is formed again inside the pressing cylinder 21. Water from the water tank 8 is automatically replenished into the pressing cylinder 21 through the bellows 28 and the one-way inlet valve 29. This cycle is repeated to gradually reduce the adhesion resistance between the hose and the tube core, completing the initial pressing and core removal process. The buffer spring 25 adapts to the high resistance in the initial stage of core removal, preventing the power source from directly bearing the peak pressure.Meanwhile, the spiral discharge port 214 ensures uniform water flow distribution, avoiding the problems of power source wear and high local resistance found in existing equipment;

[0045] Furthermore, through the coordinated operation of the quick-release mechanism 3, during the initial stamping and core removal cycle, the infrared sensor 36 at the top of the limiting rod 27 monitors the position change of the indicator 37 on the hole pressing rod 24 in real time. As the number of core removal cycles increases, the resistance between the hose and the core gradually decreases, and the compression of the buffer spring 25 gradually decreases. When the resistance decreases to the point where the buffer spring 25 can push the core without compression, the infrared sensor 36 no longer senses the indicator 37. At this time, the system determines that the core removal resistance has dropped to a low resistance state. After the hydraulic rod 22 completes the last lowest position press, it stops working. The system automatically controls the opening of the solenoid valve 34 above the branch pipe 33 and simultaneously starts the high-pressure water pump 31. Water is drawn from the water storage tank 8 and delivered to the distribution pipe 32 through the output end. The distribution pipe 32 evenly distributes the water flow to multiple branch pipes 33. The water flow flows through the branch pipes 33 and the three-way valve 35 into the connecting pipe 210, and then through the connecting water pipe 212 to the conical extrusion hole block 7. Finally, it is continuously injected into the hose through the spiral outlet 214. Since the core removal resistance has been reduced at this time, the stable high-pressure water flow output by the high-pressure water pump 31 is sufficient to quickly push the core to move along the hose axis, realize the rapid removal of the core, and complete the entire core removal operation. This realizes the automatic switching between initial pressing and rapid core removal. After the resistance is reduced, the water supply efficiency is improved by the high-pressure water pump 31, solving the problems of long core removal time and cumbersome manual switching operation for ultra-long hoses.

[0046] Simultaneously, the core removal process is completed through the cleaning and drying mechanism 4. After the core is completely removed from the tubing, the pressing cylinder 5 is activated. The telescopic end of the pressing cylinder 5 drives the conical extrusion hole block 7 to retract in the opposite direction, releasing the clamping and fixing of the tubing. The expanded rubber ball 48 with the built-in central skeleton ball 47 is placed into one end of the tubing. The pressing cylinder 5 is activated again, pushing the conical extrusion hole block 7 to reset, re-sealing and clamping the tubing, ensuring that the airflow can effectively push the expanded rubber ball 48 to move. The air pump 41 and the heating wire 44 inside the ventilation pipe 43 are activated. The air pump 41 draws in outside air and delivers it to the ventilation pipe 43 through the air supply pipe 42. The air is heated to the set temperature by the heating wire 44 in the ventilation pipe 43, forming hot air. The hot air is distributed through the ventilation pipe 43 to multiple telescopic hoses 45, and then delivered to a single... The hot air is injected into the conical extrusion hole block 7 through the air inlet pipe 46 and then into the hose through the spiral outlet 214. The thrust of the hot air drives the expansion rubber ball 48 to move along the hose axis. The outer side of the expansion rubber ball 48 is in close contact with the inner wall of the hose. During the movement, it scrapes away the water stains and a small amount of rubber debris remaining on the inner wall of the hose. After the expansion rubber ball 48 is discharged from the other end of the hose, hot air is continuously introduced into the hose. The spiral hot air sprayed from the spiral outlet 214 can evenly cover the inner wall of the hose and quickly remove the residual trace water stains, achieving thorough drying of the inner wall of the hose. This design realizes the integration of cleaning and drying of water stains on the inner wall of the hose after core removal. The spiral airflow ensures uniform drying and solves the problem that residual water stains on the hose will cause material damage and require additional cleaning and drying processes.
