Description

Technical Field

[0001] This application relates to the field of TPV shaping, and more particularly to a TPV shaping device. Background Technology

[0002] The manufacturing of various fluid transmission pipes in automobiles typically involves key steps such as rubber mixing, extrusion, and molding. In the final shaping stage, the process routes used for pipes made of different materials are drastically different. For example, nylon pipes mainly rely on high-temperature steam for shaping, while traditional rubber pipes achieve cross-linking and shaping through vulcanization. This constitutes the long-standing technical paradigm followed in the industry.

[0003] Thermoplastic vulcanizate (TPV), a high-performance material combining the elasticity of rubber and the plasticity of plastic, is increasingly widely used in automotive tubing. However, due to limitations in early technology, most TPV tubing shaping processes still employ vulcanization methods similar to those used for rubber hoses. While this process allows for final shaping, it involves vulcanization reactions under high temperature and pressure, resulting in high equipment and energy costs. Furthermore, the vulcanization process may generate waste gases containing sulfur or other organic compounds, requiring additional exhaust gas treatment systems. Overall, its environmental performance is poor, contradicting the current trend of green manufacturing. Summary of the Invention

[0004] To reduce production costs, this application provides a TPV shaping device.

[0005] The TPV shaping device provided in this application adopts the following technical solution: A TPV shaping device includes a frame, a shaping component, an inlet pipe, and an outlet pipe. The shaping component is fixedly connected to the frame, and a shaping groove is provided at one end of the shaping component away from the frame. The shaping groove is used for embedding a TPV tube. The inlet pipe and the outlet pipe are both fixedly connected to the shaping component and are used to connect the two ends of the TPV tube.

[0006] By adopting the above technical solution, the TPV pipe body is embedded in the shaping groove of the shaping part and connected to it by the feed pipe and the discharge pipe. Hot steam and cold water are introduced in sequence to shape the TPV pipe body. This eliminates the traditional vulcanization shaping process, fundamentally avoids the high energy consumption and waste gas treatment problems caused by the vulcanization reaction, significantly reduces production costs, and meets the requirements of green and environmentally friendly manufacturing.

[0007] Preferably, the shaping component includes a fixing rod, a support rod, a shaping rod, and a connector. The fixing rod is fixedly connected to the outer wall of the frame. One end of the support rod is fixedly connected to the outer wall of the fixing rod, and the other end of the support rod is fixedly connected to the outer wall of the shaping rod. The shaping groove is provided on the shaping rod. Both ends of the fixing rod are bent towards the support rod to form connecting rods. The connecting rods are provided on both sides of the shaping rod. The connector is slidably connected to the connecting rod. The feed pipe and the discharge pipe are respectively fixedly connected to the two connectors.

[0008] By adopting the above technical solution, a stable frame consisting of a fixed rod, a support rod, and a shaping rod is used to ensure the structural rigidity and positional accuracy of the shaping groove during the TPV tube shaping process. At the same time, the joint is slidably connected to the connecting rod formed by bending the two ends of the fixed rod, which facilitates the disassembly and assembly of the TPV tube and adapts to different specifications of TPV tubes. This greatly improves the adaptability and versatility of the device and realizes rapid shape change and efficient shaping.

[0009] Preferably, a limiting plate and a positioning plate are fixedly connected to the outer wall of the connecting rod, and the positioning plate and the limiting plate are respectively located on both sides of the joint.

[0010] By adopting the above technical solution, precise physical limits and reference positioning are provided for the sliding stroke of the joint. This not only effectively prevents the joint from slipping during the adjustment process, but also ensures that multiple joints can be quickly and accurately adjusted and fixed in the preset working position. This ensures the coaxiality and spacing accuracy between the feed pipe and the discharge pipe, and greatly improves the repeatability of the equipment settings and the stability of the shaping process.

[0011] Preferably, it further includes a spring, a stop block, and a shape memory alloy. The outer wall of the connecting rod is provided with a mounting groove, which is located between the limiting plate and the positioning plate. One end of the spring is fixedly connected to the bottom of the mounting groove, and the other end of the spring is fixedly connected to the stop block. The stop block is slidably connected to the wall of the mounting groove and faces the outer wall of the shaping rod to abut against the joint. One end of the shape memory alloy is fixedly connected to the bottom of the mounting groove, and the other end of the shape memory alloy is used to abut against the stop block. The material of the shaping component is a thermally conductive material.

[0012] By adopting the above technical solution, a smart, adaptive pipe locking and compensation mechanism is formed by combining shape memory alloy with a spring and using a heat-conducting shaping component as a heat conduction medium. Under the high-temperature environment required for shaping, the shape memory alloy expands due to heat, driving the stop block to press the joint, achieving automatic and stable locking, effectively preventing the pipe from loosening due to thermal stress rebound or vibration. When cooled, the shape memory alloy contracts, the spring resets and the stop block retracts, which facilitates the quick unlocking and adjustment of the joint. Thus, while ensuring high stability in the shaping process, it also takes into account operational efficiency and achieves intelligent response and self-adjustment to temperature changes.

[0013] Preferably, it also includes a sealing ring, the fixing rod is provided with a first air passage, the first air passage is connected to the mounting groove, the sealing ring is coaxially fixedly connected to the outer wall of the stop block, the outer wall of the sealing ring abuts against the groove wall of the mounting groove, and the sealing ring is located on the side of the first air passage away from the bottom of the mounting groove.

[0014] By adopting the above technical solution, the sealing ring reduces the probability of gas leakage in the first air passage. When hot steam is introduced into the TPV tube, the gas in the first air passage heats up and expands, pushing the spring to stretch and limit the movement of the joint. The gas conducts heat to the shape memory alloy. After the shape memory alloy reaches the deformation temperature, it deforms and elongates, allowing the stop block to stably abut against the joint. When cold water is introduced into the TPV tube, the TPV tube is cooled down, and the joint is cooled down at the same time. When the shape memory alloy deforms and contracts, the spring returns to its original position, and the stop block returns to its original position. At this time, the TPV tube is shaped. The temperature of the shaping component can be judged by the position of the stop block, thereby roughly judging the state of the TPV tube and preventing users from touching the TPV tube when hot steam is introduced into it, thus protecting people's personal safety. When the TPV tube is not shaped, the half ring can be rotated to disassemble it, preventing the joint from sliding and reducing the probability of product scrap due to operator error.

[0015] Preferably, the support rod is provided with a second air passage, and the bottom of the shaping groove is provided with an opening, and the second air passage is connected to the opening and the first air passage.

[0016] By adopting the above technical solution, when hot steam is passed through the TPV tube, the TPV tube expands due to heat and is clamped in the shaping groove, which facilitates shaping. At this time, the shaping component conducts heat, and the gas in the first and second air channels expands thermally, pushing the stop block to move and limiting the joint. When the shape memory alloy reaches the deformation temperature, it deforms and elongates, and the stop block moves further to stably limit the joint. At the same time, the pressure in the first and second air channels decreases, adsorbing the TPV tube. When cold water is passed through the TPV tube, the TPV tube begins to cool and shape, and is stably adsorbed in the shaping groove by the opening, preventing the TPV tube from deforming due to the gravity of the cooling water during the cooling process. The gas in the first and second air channels begins to cool down, and the pressure difference between the inside and outside of the second air channel further increases, so that the TPV tube is stably embedded in the shaping groove until the shape memory alloy reaches the deformation and contraction temperature. At this time, the TPV tube has been shaped, the spring returns to its original position, the stop block returns to its original position, and the sliding joint moves the joint away from the TPV tube, making it easy to remove the shaped TPV tube.

[0017] Preferably, the connector includes a sliding ring, a fixed half-ring, a rotating half-ring, and a locking block. The inner wall of the sliding ring is slidably connected to the outer wall of the connecting rod. The outer wall of the fixed half-ring is fixedly connected to the outer wall of the sliding ring. One end of the rotating half-ring is hinged to one end of the fixed half-ring. The locking block is hinged to the other end of the fixed half-ring. The locking block has a locking groove. A locking strip is fixedly connected to the outer wall of the rotating half-ring. The locking strip is used to embed into the locking groove. The feed pipe and the discharge pipe are both fixedly connected to the inner wall of the fixed half-ring. The inner walls of the feed pipe and the discharge pipe are both used for the TPV pipe body to abut against.

[0018] By adopting the above technical solution, when installing a TPV pipe, both ends of the TPV pipe are inserted into the feed pipe and discharge pipe, respectively. Rotating the half-ring causes the locking block to rotate, and the locking strip and slot achieve rapid locking. The fixed half-ring and the rotating half-ring together compress the feed pipe and discharge pipe, clamping the TPV pipe. When disassembling the TPV pipe, the locking block and rotating half-ring reset sequentially, the sliding ring slides away from the TPV pipe, and the TPV pipe is removed. This makes the clamping and disassembly of the TPV pipe extremely convenient, significantly improving the efficiency of pipe replacement and maintenance, while ensuring the stability and sealing of the pipe's connection with the feed and discharge pipes during the shaping process.

[0019] Preferably, the edge of the stop block away from the spring is rounded. When the spring is not subjected to external force, the rounded corner extends out of the groove of the mounting slot and is used to abut against the inner wall of the sliding ring.

[0020] By adopting the above technical solution, when the connector is away from the TPV tube body, the sliding ring abuts against the upper end face of the stop block during the sliding process, causing the stop block to move, the spring to contract, the pressure in the first air passage and the second air passage to increase, pushing the TPV tube body out of the shaping groove, making it easier to remove the TPV tube body.

[0021] In summary, this application includes at least one of the following beneficial technical effects: The TPV pipe body is embedded in the shaping groove of the shaping part and connected to it by the feed pipe and the discharge pipe. Hot steam and cold water are introduced in sequence to shape the TPV pipe body. This process eliminates the traditional vulcanization shaping process, fundamentally avoids the high energy consumption and waste gas treatment problems caused by the vulcanization reaction, significantly reduces production costs, and meets the requirements of green and environmentally friendly manufacturing. By combining shape memory alloy with a spring and using a heat-conducting shaping component as a heat transfer medium, an intelligent and adaptive pipe locking and compensation mechanism is formed. Under the high-temperature environment required for shaping, the shape memory alloy expands due to heat, driving the stop block to press the joint, achieving automatic and stable locking, effectively preventing the pipe from loosening due to thermal stress rebound or vibration. When cooled, the shape memory alloy contracts, the spring resets and the stop block retracts, providing convenience for quick unlocking and adjustment of the joint. Thus, while ensuring high stability in the shaping process, it also takes into account operational efficiency, realizing intelligent response and self-adjustment to temperature changes. When hot steam is passed through the TPV tube, the TPV tube expands due to heat and is clamped in the shaping groove, facilitating shaping. At this time, the shaping component conducts heat, and the gas in the first and second air channels expands thermally, pushing the stop block to move and limit the joint. When the shape memory alloy reaches the deformation temperature, it deforms and elongates, and the stop block moves further to stably limit the joint. At the same time, the pressure in the first and second air channels decreases, adsorbing the TPV tube. When cold water is passed through the TPV tube, the TPV tube begins to cool and shape, and is stably adsorbed in the shaping groove by the opening, preventing the TPV tube from deforming due to the gravity of the cooling water during the cooling process. The gas in the first and second air channels begins to cool down, and the pressure difference between the inside and outside of the second air channel further increases, making the TPV tube stably embedded in the shaping groove until the shape memory alloy reaches the deformation and contraction temperature. At this time, the TPV tube has been shaped, the spring returns to its original position, the stop block returns to its original position, and the sliding joint moves the joint away from the TPV tube, making it easy to remove the shaped TPV tube.

The six shaping parts 4 are divided into two groups, and the two groups of shaping parts 4 are spaced apart along the axis of the rotating column 31. Each group of shaping parts 4 has three shaping parts 4, and the three shaping parts 4 are evenly spaced along the length of the fixed support rod 38. The shaping parts 4 are made of thermally conductive material. The shaping parts 4 include a fixed rod 41, a support rod 42, a shaping rod 43, and a connector 44. The fixed rod 41 is fixedly connected to the outer wall of the fixed support rod 38.

The connector 44 includes a sliding ring 441, a fixed half-ring 442, a rotating half-ring 443, and a locking block 444. The inner wall of the sliding ring 441 is slidably connected to the outer wall of the connecting rod 411, and the outer wall of the fixed half-ring 442 is fixedly connected to the outer wall of the sliding ring 441.

The outer wall of the rotating half ring 443 is fixedly connected with a locking strip 4431. The locking strip 4431 is used to embed into the locking groove 4441. When the rotating half ring 443 rotates and forms a circle with the fixed half ring 442, the locking block 444 rotates so that the locking strip 4431 is embedded in the locking groove 4441, thereby achieving relative fixation between the rotating half ring 443 and the fixed half ring 442.

The edge of the stop block 72 away from the spring 71 is provided with a rounded corner 721. When the spring 71 is not subjected to external force, the rounded corner 721 extends out of the groove opening of the mounting groove 414 and abuts against the inner wall of the sliding ring 441. One end of the shape memory alloy 73 is fixedly connected to the bottom of the mounting groove 414, and the other end of the shape memory alloy 73 abuts against the lower end of the stop block 72.

[0043] Reference Figure 2 and Figure 7 There are three discharge ports 82, and each discharge port 82 is set in correspondence with the feed pipe 5. The feed pipe 5 is coaxially fixedly connected to the inner wall of the discharge port 82. There are multiple feed ports 83, which are respectively connected to the outlets of the hot steam generator and the water pump.

[0044] The implementation principle of the TPV shaping device in this application embodiment is as follows: A TPV tube is embedded in the shaping groove 431 of the shaping component 4, and connected to it via the inlet pipe 5 and outlet pipe 6. Hot steam and cold water are sequentially introduced to shape the TPV tube. When hot steam is introduced into the TPV tube, the TPV tube expands due to heat and is clamped in the shaping groove 431, facilitating shaping. At this time, the shaping component 4 conducts heat, and the gas in the first air passage 415 and the second air passage 421 expands thermally, pushing the stop block 72 to move and limiting the connector 44. When the shape memory alloy 73 reaches the deformation temperature, it deforms and elongates, and the stop block 72 moves further to stably limit the connector 44. Simultaneously, the pressure in the first air passage 415 and the second air passage 421 decreases, adsorbing the TPV tube. When cold water is introduced into the TPV tube, the TPV tube begins to cool and shape, and is stably adsorbed by the inlet 4311. The TPV tube is attached to the shaping groove 431 to prevent deformation of the TPV tube due to the gravity of the cooling water during the cooling process. The gas in the first air passage 415 and the second air passage 421 begins to cool down, and the pressure difference between the inside and outside of the second air passage 421 further increases, so that the TPV tube is stably embedded in the shaping groove 431 until the shape memory alloy 73 reaches the temperature of deformation and contraction. At this time, the TPV tube has been shaped. The spring 71 returns to its original position, causing the stop block 72 to return to its original position. The sliding joint 44 moves away from the TPV tube, making it easier to remove the shaped TPV tube. When the joint 44 moves away from the TPV tube, the sliding ring 441 slides against the upper end face of the stop block 72, causing the stop block 72 to move. The spring 71 contracts, and the pressure in the first air passage 415 and the second air passage 421 increases, pushing the TPV tube out of the shaping groove 431, making it easier to remove the TPV tube.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
