Description

Technical Field

[0001] This application relates to the field of pipe processing technology, and in particular to a pipe demolding device and processing line. Background Technology

[0002] In the existing process of shaping the cross-section of hollow pipes using a combination of a core and an outer mold, the pipe is inserted into the forming through-hole of the outer mold, and the core is placed inside the pipe cavity for internal support and shaping. After the pipe cross-section is shaped, the pipe needs to be separated from the core for demolding. However, after shaping, the inner wall of the pipe and the outer wall of the core are tightly fitted, and the pipe exerts a clamping force on the core, resulting in significant demolding resistance and making demolding difficult.

[0003] In the current production process, demolding is mostly done manually by dragging and prying. This is not only labor-intensive and inefficient, but also prone to uneven force application, which can cause pipe wall dents, deformations, and surface scratches, affecting the pipe forming accuracy and appearance quality. At the same time, manual demolding relies on the operator's experience, making it difficult to achieve standardized operations, resulting in low automation and an inability to meet the needs of large-scale continuous production. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this application provides a demolding device for pipes, including a rolling mechanism and a separation mechanism. The rolling mechanism is used to roll the pipe, and the separation mechanism is located downstream of the rolling mechanism to separate the rolled pipe from its internal mold core. The rolling mechanism includes a roller assembly and a power assembly, wherein the power assembly and the roller assembly are spaced apart, and the roller assembly includes at least two rollers; The pipe and its internal mold core are disposed in the gap between the at least two rollers, and each roller abuts against the outer wall of the pipe. The power assembly is used to drive one of the pipe and the roller assembly to move relative to the other, so that the rollers can roll the pipe.

[0005] The roller assembly includes two rollers located on opposite sides of the tube along its radial direction to clamp the tube and the mold core inside it.

[0006] The roller assembly includes at least three rollers, each of which is spaced apart along the outer periphery of the cross-section of the pipe to form a multi-point circumferential limit on the pipe.

[0007] The rolling mechanism further includes a mounting bracket and an adjustment component. The roller assembly is mounted on the mounting bracket, and the adjustment component is connected to at least one of the rollers in the roller assembly to adjust the distance between the roller and the mounting surface of the mounting bracket, thereby adjusting the distance between each roller in the roller assembly.

[0008] The rolling mechanism further includes a mounting bracket and a moving component. The mounting bracket and the moving component are spaced apart. The roller assembly includes a fixed roller and a moving roller. The fixed roller is mounted on the mounting bracket, and the moving roller is mounted on the moving component. The moving component is used to drive the moving roller to move relative to the mounting bracket, thereby changing the distance between the fixed roller and the moving roller.

[0009] The movable component includes a first adjusting guide rail and a movable member. One end of the first adjusting guide rail is disposed adjacent to the mounting bracket. The movable member is slidably disposed on the first adjusting guide rail, and the movable roller is mounted on the movable member. The movable member is used to move along the first adjusting guide rail to drive the movable roller to move.

[0010] The movable component further includes a base, which includes a vertical plate and a horizontal plate arranged perpendicularly to each other, and the first adjusting guide rail is disposed on the horizontal plate; The movable component further includes a first frame, a second adjusting guide rail, a second frame, and a cylinder. The second adjusting guide rail is disposed on the first frame, and the extension direction of the second adjusting guide rail is parallel to the extension direction of the first adjusting guide rail. The second frame is slidably disposed on the first frame via the second adjusting guide rail. The movable roller and the cylinder are disposed on the second frame, and the output shaft of the cylinder is connected to the vertical plate. The cylinder is used to drive the second frame to move relative to the first frame along the second adjusting guide rail, thereby driving the movable roller to move.

[0011] The mounting bracket includes at least a top plate, a bottom plate, and multiple mounting supports. The two ends of the mounting supports are connected to the top plate and the bottom plate, respectively. The rollers are installed on the side of the bottom plate near the top plate and the side of the top plate near the bottom plate. The rolling mechanism further includes a roller attachment, which has multiple rollers. A mounting block on the roller attachment is fixed to the mounting support, so that the roller attachment and the roller assembly are spaced apart along the axial direction of the pipe. The pipe is disposed in the gap formed by the rollers on the roller attachment, so that the rollers on the roller attachment can roll the pipe.

[0012] To solve the above-mentioned technical problems, this application also provides a pipe processing production line, including at least one shaping device and a demolding device as described above, wherein the at least one shaping device is used to perform at least one shaping process on the pipe to be processed so that the pipe to be processed is shaped into a target pipe, and the demolding device is used to separate the target pipe and its internal mold core.

[0013] The at least one shaping device includes a first shaping device and a second shaping device. The second shaping device is located downstream of the first shaping device. The first shaping device is used to shape the pipe to be processed into a preformed pipe in a moldless support manner. The second shaping device is used to shape the preformed pipe into the target pipe under the support of a mold core.

[0014] The beneficial effects of this application are as follows: Unlike existing technologies, the pipe demolding device provided in this application includes a rolling mechanism and a separation mechanism. The rolling mechanism is used to roll the pipe, and the separation mechanism is located downstream of the rolling mechanism to separate the rolled pipe from its internal mold core. The rolling mechanism includes a roller assembly and a power assembly, with the power assembly and roller assembly spaced apart. The roller assembly includes at least two rollers. The pipe and its internal mold core are positioned in the gap between the at least two rollers, and each roller abuts against the outer wall of the pipe. The power assembly drives one of the pipe and the roller assembly to move relative to the other, so that the rollers can roll the pipe. The rolling mechanism rolls the pipe to release the contact extrusion stress between the pipe and the internal mold core, alleviates the residual internal stress generated during the pipe shaping process, and weakens the holding and locking effect of the pipe on the mold core, thereby reducing demolding friction and demolding difficulty. At the same time, the separation mechanism separates the rolled pipe and the internal mold core, realizing the automation of the separation of the pipe and the mold core, and further improving demolding efficiency.

[0017] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0018] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0019] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Furthermore, "many" in this application means two or more. Moreover, the term "at least one" in this application means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C. Furthermore, the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0021] To address the problems of low efficiency and high difficulty in manual demolding in existing technologies, this application provides a demolding device for pipes. The device aims to first reduce and release the contact extrusion stress between the pipe and the internal mold core through a rolling mechanism, thereby reducing the difficulty of demolding, and then achieve automatic separation of the pipe and the mold core through a separation mechanism.

[0022] Please see Figure 1 The demolding device 1 for pipes provided in this application includes a rolling mechanism 11 and a separation mechanism 12.

[0023] The rolling mechanism 11 is used to roll the pipe, and the separation mechanism 12 is located downstream of the rolling mechanism 11 to separate the rolled pipe from its internal mold core.

[0024] Among them, the rolling mechanism 11 can roll the outer wall of the pipe, balance the local extrusion state between the pipe and the mold core, release the contact stress concentrated on the contact surface, make the inner wall of the pipe and the outer wall of the mold core more evenly bonded, avoid excessive clamping and jamming caused by local stress concentration, effectively reduce demolding resistance and reduce the demolding difficulty of the mold core.

[0025] Furthermore, the separation mechanism 12 is located downstream of the rolling mechanism 11. It receives the pipe and its internal mold core after being rolled by the rolling mechanism 11 and automatically separates the pipe from the mold core, thereby realizing automatic demolding of the pipe. This reduces the pipe wall dents, deformations, and surface scratches caused by manual demolding, which affect the pipe forming accuracy and appearance quality, improves the demolding efficiency of the pipe, and enhances the practicality of the demolding device 1.

[0026] Furthermore, the rolling mechanism 11 includes a roller assembly 111 and a power assembly 112, which are spaced apart. The roller assembly 111 includes at least two rollers 1111.

[0027] The pipe and its internal mold core are set in the gap formed by all the rollers 1111 in the roller assembly 111. Each roller 1111 abuts against the outer wall of the pipe. The power assembly 112 is used to drive one of the pipe and the roller assembly 111 to move relative to the other so that the rollers 1111 can roll the pipe.

[0028] In some embodiments, the power component 112 can be connected to at least one roller 1111 in the roller assembly 111, thereby driving the roller 1111 to rotate. Since each roller 1111 abuts against the outer wall of the pipe, the rotation of the roller 1111 can drive the pipe to move linearly, and the pipe can drive other rollers 1111 connected to the power component 112 to rotate. That is, the roller 1111 connected to the power component 112 can be defined as the driving wheel, and the other rollers 1111 in the roller assembly 111 that are not connected to the power component 112 are the driven wheels. Through the cooperation of each roller 1111, the relative movement of the pipe and the roller assembly 111 can be realized. Each roller 1111 rolls the outer wall of the pipe to reduce the demolding difficulty of the pipe and its internal mold core.

[0029] The power component 112 can drive the roller 1111 to rotate counterclockwise and clockwise alternately, so that the roller 1111 drives the pipe and the mold core to move back and forth in a straight line relative to the roller component 111. The roller 1111 rolls the outer wall of the pipe multiple times, thereby improving the rolling efficiency of the rolling mechanism 11.

[0030] In some embodiments, the power assembly 112 may also be disposed downstream of the roller assembly 111 for clamping one end of the mold core or the tube and driving the mold core and the tube to move back and forth relative to the roller assembly 111 so that the roller 1111 rolls the tube sleeved on the mold core.

[0031] The power assembly 112 can clamp one end of the pipe or one end of the mold core, preferably clamping one end of the mold core to avoid pipe wall deformation caused by clamping the pipe. Then, the power assembly 112 can move relative to the roller assembly 111 in a straight line to drive the mold core and the pipe to move relative to the roller assembly 111. The straight movement direction of the power assembly 112 can be perpendicular to the axis of each roller 1111 in the roller assembly 111 to ensure that the movement direction of the pipe and the mold core is perpendicular to the axis of the roller 1111. The wheel surface of the roller 1111 abuts against the outer wall of the pipe to roll the pipe.

[0032] Furthermore, the power component 112 can alternately move closer to the roller assembly 111 and away from the roller assembly 111 to drive the tube and the mold core to move back and forth relative to the roller assembly 111, and the roller 1111 rolls the outer wall of the tube multiple times.

[0033] By setting the rolling mechanism 11, which includes a roller assembly 111 and a power assembly 112, the roller assembly 111 and the power assembly 112 cooperate to roll the pipe, thereby reducing the difficulty of demolding the pipe.

[0034] In some embodiments, the power assembly 112 may include a power element 1121 and a first moving guide rail 1122. The first moving guide rail 1122 is disposed downstream of the roller assembly 111, with one end of the first moving guide rail 1122 spaced apart from the roller assembly 111. The power element 1121 is slidably disposed on the first moving guide rail 1122, thereby clamping one end of the pipe or one end of the mold core inside the pipe, thereby driving the pipe and the mold core inside the pipe to move relative to the roller assembly 111. The extending direction of the first moving guide rail 1122 may be parallel to the axial direction of the pipe, thereby driving the pipe and the mold core to move linearly back and forth along the axial direction of the pipe, so that the roller 1111 rolls the pipe along the axial direction of the pipe, improving the rolling efficiency of the roller assembly 111 on the pipe.

[0035] Optionally, the roller assembly 111 may include two rollers 1111, which are located on opposite sides of the tube along the radial direction of the tube to clamp the tube and the mold core inside it.

[0036] Specifically, two rollers 1111 are positioned on opposite sides of the pipe to roll the two opposing surfaces of the pipe. Because the two rollers 1111 are positioned on opposite sides of the pipe, they can fix the radial direction of the pipe during the rolling process, preventing radial movement of the target pipe. Specifically, the roller 1111 on the first side of the pipe applies a force towards the second side during rolling, while the roller 1111 on the second side applies a force towards the first side. The forces exerted by the two rollers cancel each other out, thus fixing the radial movement of the pipe. This prevents radial movement of the pipe from affecting the rolling effect and improves the rolling efficiency of the rollers 1111.

[0037] It is understandable that there are two opposing surfaces in the radial cross-sectional shape of the pipe, and two rollers 1111 can be set on opposite sides of the pipe. The rollers 1111 roll the opposite sides of the pipe, and at the same time, they can restrict the radial movement of the pipe during the rolling process to ensure the rolling efficiency of the pipe.

[0038] Optionally, the roller assembly 111 includes at least three rollers 1111, each roller 1111 being spaced apart along the outer periphery of the pipe section to form multi-point circumferential restraint on the pipe.

[0039] Specifically, if there are no two opposing surfaces in the radial cross-sectional shape of the pipe, for example, if the radial cross-sectional shape is a triangle or a regular pentagon, then the roller assembly 111 may include at least three rollers 1111. Each roller 1111 is spaced apart along the outer periphery of the pipe cross-section, and each roller 1111 abuts against the corresponding outer wall of the pipe to form multi-point circumferential limiting of the pipe.

[0040] In the process of rolling the pipe with rollers 1111, since the pipe does not have two opposing surfaces, the force exerted on the pipe by two rollers 1111 alone cannot be completely canceled out. Therefore, this embodiment proposes that in this case, the roller assembly 111 may include at least three rollers 1111. The at least three rollers 1111 can provide forces to the pipe in different directions, and the separation of multiple forces cancels each other out, so that the resultant force on the pipe in the radial direction is 0. The multiple rollers 1111 form multi-point circumferential restraint on the pipe, ensuring that the pipe will not move radially during the rolling process, thereby improving the rolling efficiency of the roller assembly 111 on the pipe.

[0041] Alternatively, please continue reading Figure 2 The rolling mechanism 11 also includes a mounting bracket 113 and an adjusting component 114. The roller assembly 111 is mounted on the mounting bracket 113, and the adjusting component 114 is connected to at least one roller 1111 in the roller assembly 111 to adjust the distance between the roller 1111 and the mounting surface of the mounting bracket 113, thereby adjusting the distance between each roller 1111 in the roller assembly 111. The adjusting component 114 can be a stepper motor or a pneumatic telescopic rod, etc.

[0042] Specifically, all the rollers 1111 of the roller assembly 111 can be mounted on the mounting bracket 113. The mounting bracket 113 supports the rollers 1111 of the roller assembly 111. Taking a roller assembly 111 comprising two rollers 1111 as an example, as mentioned above, if the roller assembly 111 comprises two rollers 1111, the two rollers 1111 are arranged on opposite sides of the pipe. Figure 2 As shown, the two rollers 1111 can be installed on the upper and lower sides of the same space of the mounting bracket 113, respectively.

[0043] Furthermore, the adjusting component 114 can be installed on the upper side of the mounting bracket 113 and connected to the roller 1111 on the upper side of the mounting bracket 113. The adjusting component 114 can then adjust the distance between the upper roller 1111 and the mounting surface of the mounting bracket 113 (i.e., the upper surface of the mounting bracket 113), thereby adjusting the distance between the two rollers 1111. Specifically, when the outer diameter of the pipe is relatively large, the adjusting component 114 can drive the roller 1111 to move closer to the mounting surface of the mounting bracket 113, thereby reducing the distance between the roller 1111 and the mounting surface of the mounting bracket 113 and increasing the distance between the two rollers 1111. This ensures that the pipe can be positioned within the gap between the two rollers 1111, allowing the two rollers 1111 to roll over the pipe.

[0044] Alternatively, when the outer diameter of the pipe is relatively small, the adjusting component 114 can drive the roller 1111 to move away from the mounting surface of the mounting bracket 113, thereby increasing the distance between the roller 1111 and the mounting surface of the mounting bracket 113 and decreasing the distance between the two rollers 1111. This ensures that when the pipe is placed in the gap between the two rollers 1111, the two rollers 1111 can abut against the outer wall of the pipe, allowing the two rollers 1111 to roll the pipe.

[0045] In some embodiments, the mounting bracket 113 may include at least a top plate 1131, a bottom plate 1132, and a plurality of mounting supports 1133. The two ends of the mounting supports 1133 are respectively connected to the top plate 1131 and the bottom plate 1132 to support the bottom plate 1132 and the top plate 1131, allowing the top plate 1131 and the bottom plate 1132 to form a space for accommodating the rollers 1111. Furthermore, rollers 1111 are mounted on both the side of the bottom plate 1132 near the top plate 1131 and the side of the top plate 1131 near the bottom plate 1132. That is, as described above, two rollers 1111 can be respectively mounted on the side of the top plate 1131 near the bottom plate 1132 and the side of the bottom plate 1132 near the top plate 1131, to form a gap to accommodate the passage of pipes. Furthermore, the adjustment component 114 can be disposed on the side of the top plate 1131 away from the bottom plate 1132, and connected to the roller 1111 disposed on the top plate 1131, for adjusting the distance between the roller 1111 and the top plate 1131, thereby adjusting the distance between the two rollers 1111.

[0046] In some embodiments, the adjustment component 114 may be a push cylinder, the output end of which passes through the top plate 1131 and is connected to the roller 1111. The distance between the roller 1111 and the top plate 1131 can be adjusted by extending or shortening the output end of the push cylinder.

[0047] In some embodiments, the adjusting component 114 can also be connected to all the rollers 1111 mounted on the mounting bracket 113 to adjust the distance between different rollers 1111 and the mounting surface of the mounting bracket 113 synchronously or asynchronously, thereby adjusting the distance between each roller 1111 so that the gap formed between each roller 1111 can be adapted to the outer diameter of the pipe, and the movement of multiple rollers 1111 can improve the adjustment efficiency between rollers 1111.

[0048] In some embodiments, if the roller assembly 111 includes two or more rollers 1111, the adjusting component 114 may be connected to at least one roller 1111 in the roller assembly 111, or to all rollers 1111 in the roller assembly 111, to adjust the distance between each roller 1111.

[0049] By setting the adjustment component 114 to connect the roller assembly 111 installed on the mounting bracket 113, the adjustment component 114 can adjust the gap formed by each roller 1111 of the roller assembly 111 and the fit with the outer diameter of the pipe, so as to ensure that each roller 1111 can abut against the outer wall of the pipe and ensure the rolling efficiency of the rolling mechanism 11 on the pipe.

[0050] In some embodiments, the rolling mechanism 11 may further include a cleaning component 115, which may be spaced apart from the roller 1111 and used to clean the surface of the roller 1111 during the rolling process of the roller 1111 on the pipe. This is to prevent the roller 1111 from being contaminated or dusty when rolling the outer wall of the pipe, thus preventing dirt from being transferred to the outer wall of the pipe or dust from scratching the outer wall of the pipe.

[0051] The cleaning component 115 may include a cleaning roller, etc.

[0052] Optionally, such as Figure 3 As shown, the rolling mechanism 11 may further include a mounting bracket 113 and a moving component 116. The mounting bracket 113 and the moving component 116 are spaced apart. The roller assembly 111 includes a fixed roller 1111a and a moving roller 1111b. The fixed roller 1111a is mounted on the mounting bracket 113, and the moving roller 1111b is mounted on the moving component 116. The moving component 116 is used to drive the moving roller 1111b to move relative to the mounting bracket 113, so as to change the distance between the fixed roller 1111a and the moving roller 1111b.

[0053] Specifically, the fixed roller 1111a of the roller assembly 111 is mounted on the mounting bracket 113, while the movable roller 1111b of the roller assembly 111 is mounted on the movable assembly 116. Since the movable assembly 116 is spaced apart from the mounting bracket 113, the movable assembly 116 can drive the movable roller 1111b to move relative to the mounting bracket 113, so that the movable roller 1111b moves closer to the fixed roller 1111a or moves away from the fixed roller 1111a, thereby changing the distance between the fixed roller 1111a and the movable roller 1111b. This allows the gap formed between the movable roller 1111b and the fixed roller 1111a to adapt to pipes of different outer diameters, thereby improving the rolling efficiency of the rolling mechanism 11 on the pipe.

[0054] The moving component 116 drives the moving roller 1111b to move, adjusting the distance between the fixed roller 1111a and the moving roller 1111b, thereby improving the adaptability of the roller component 111 to pipes of different outer diameters and increasing the rolling efficiency of the rolling mechanism 11 on the pipes.

[0055] It is understood that this application does not limit the number of rollers 1111 included in the roller assembly 111, or the specific position of the rollers 1111 connected to the adjustment assembly 114 or the specific position of the rollers 1111 set on the moving assembly 116. These can be set by the user based on the specific outline shape of the pipe.

[0056] In some embodiments, as described above, the mounting bracket 113 includes a plurality of mounting posts 1133, and the moving component 116 can drive the moving roller 1111b through the gap between two mounting posts 1133 to approach or move away from the fixed roller 1111a on the mounting bracket 113.

[0057] In some embodiments, the moving component 116 may include a moving member 1161 and a first adjusting guide rail 1162. A moving roller 1111b is mounted on the moving member 1161 on the side near the mounting bracket 113, and the moving member 1161 is slidably disposed on the first adjusting guide rail 1162. The extending direction of the first adjusting guide rail 1162 may be parallel to the line connecting the fixed roller 1111a and the moving roller 1111b, so as to ensure that the moving member 1161 moves on the first adjusting guide rail 1162, driving the moving roller 1111b to move relative to the fixed roller 1111a with higher efficiency, thereby improving the efficiency of changing the distance between the rollers 1111.

[0058] In some embodiments, please refer to Figure 3 and Figure 4 The moving component 116 also includes a base 1163, which includes a vertical plate and a horizontal plate arranged perpendicularly to each other, and a first adjusting guide rail 1162 is disposed on the horizontal plate.

[0059] Furthermore, the movable component 1161 also includes a first frame 11611, a second adjusting guide rail 11612, a second frame 11613, and a cylinder 11614. The second adjusting guide rail 11612 is disposed on the first frame 11611, and the extension direction of the second adjusting guide rail 11612 is parallel to the extension direction of the first adjusting guide rail 1162. The second frame 11613 is slidably disposed on the first frame 11611 via the second adjusting guide rail 11612. The movable roller 1111b and the cylinder 11614 are disposed on the second frame, and the output shaft of the cylinder 11614 is connected to the vertical plate. The cylinder 11614 is used to drive the second frame 11613 to move relative to the first frame 11611 along the second adjusting guide rail 11612, so as to drive the movable roller 1111b to move.

[0060] Specifically, during the process of the moving component 116 driving the moving roller 1111b to move closer to the fixed roller 1111a, instead of the first frame 11611 moving relative to the base 1163 along the first adjusting guide rail 1162, the output shaft of the cylinder 11614 can extend or shorten to drive the second frame 11613 to move away from or closer to the vertical plate of the base 1163 along the second adjusting guide rail 11612. That is, the extension or shortening of the output shaft of the cylinder 11614 enables the second frame 11613 to drive the moving roller 1111b to move closer to or away from the fixed roller 1111a along the second adjusting guide rail 11612, thereby changing the distance between the fixed roller 1111a and the moving roller 1111b.

[0061] In some embodiments, the movement of the movable roller 1111b towards the fixed roller 1111a via the movable component 116 can specifically involve the first frame 11611 moving the movable roller 1111b a large distance along the first adjusting guide rail 1162 to quickly bring the movable roller 1111b closer to the fixed roller 1111a. Then, the first frame 11611 remains stationary relative to the base 1163, while the output shaft of the cylinder 11614 extends, causing the second frame 11613 to move a smaller distance along the second adjusting guide rail 11612 to precisely adjust the distance between the movable roller 1111b and the fixed roller 1111a. That is, by using the first frame 11611 to drive the movable roller 1111b for a large-scale distance adjustment, the movement efficiency of the movable roller 1111b is improved, while by using the second frame 11613 to drive the movable roller 1111b for a small-scale distance adjustment, the movement accuracy of the movable roller 1111b is improved.

[0062] In some embodiments, please continue reading Figure 5When the roller assembly 111 includes multiple rollers 1111, some rollers 1111 can be mounted on the mounting bracket 113, and some rollers 1111 can be mounted on the moving assembly 116. The mounting bracket 113 is provided with an adjusting assembly 114 for adjusting the position of the rollers 1111 on the mounting bracket 113. Specifically, it can be as follows: Figure 5 The three rollers 1111 are mounted on the mounting bracket 113, one roller 1111 is mounted on the moving component 116, and the adjusting component 114 is connected to the upper roller 1111. For ease of description, the roller 1111 connected to the adjusting component 114 or the roller 1111 mounted on the moving component 116 is defined as the moving roller 1111b, while the roller 1111 whose position does not change is defined as the fixed roller 1111a.

[0063] Furthermore, when it is necessary to adjust the distance between each roller 1111, the adjusting component 114 and the moving component 116 can synchronously or asynchronously drive the moving roller 1111b to move closer to or further away from the fixed roller 1111a, so as to ensure the fit between the gap formed between each roller 1111 and the outer diameter of the pipe.

[0064] Alternatively, the moving component 116 or the adjusting component 114 drives the moving rollers 1111b to move so that the gaps formed between the rollers 1111 adapt to pipes with different profiles.

[0065] Optional, such as Figure 6 As shown, the rolling mechanism 11 may further include a roller attachment 117, which is provided with a plurality of rollers 1171. The mounting block 1172 on the roller attachment 117 is fixed to the mounting support 1133 so that the roller attachment 117 and the roller assembly 111 are spaced apart along the axial direction of the pipe. The pipe is disposed in the gap formed by each roller 1171 on the roller attachment 117 so that the pipe is rolled by the rollers 1171 on the roller attachment 117.

[0066] The roller assembly 111 and the roller attachment 117 are spaced apart along the axial direction of the pipe, so that each roller 1111 on the roller assembly 111 and each roller 1171 on the roller attachment 117 can be spaced apart along a circumferential plane of the pipe to simultaneously roll different positions on the pipe and improve the rolling efficiency of the pipe.

[0067] Furthermore, the axial direction of the roller 1171 on the roller attachment 117 can be at an angle to the axial direction of the roller 1111 in the roller assembly 111. That is, the outer wall surface of the roller on the roller attachment 117 that abuts against the pipe is not the same as the outer wall surface of the roller 1111 in the roller assembly 111 that abuts against the pipe. This allows for more comprehensive rolling of the pipe and further improves the rolling efficiency of the pipe.

[0068] In some embodiments, the rollers 1171 on the roller attachment 117 can be mounted on the roller bracket 1173 via elastic members, thereby allowing each roller 1171 to adjust its distance from the mounting surface of the roller bracket 1173 via the elastic members. Specifically, when the pipe passes through the gap formed by the rollers 1171 on the roller attachment 117, the pipe with a larger diameter will apply a force close to its mounting surface to each roller 1171, causing the roller 1171 to compress the elastic member. At the same time, the elastic member will provide a counter-compressive force to the roller 1171, causing the roller 1171 to abut against the outer wall of the pipe. Through the design of the roller bracket 1173 and the elastic member, the roller attachment 117 does not need to be equipped with an additional power member to drive the rollers 1171 to actively adjust their distance relationship with other rollers 1171.

[0069] Optionally, please refer back to the previous section. Figure 1 The rolling mechanism 11 also includes a first support component 118, which is spaced apart from the roller assembly 111. Specifically, the first support component 118 can be located upstream of the roller assembly 111. The first support component 118 is used to receive the pipe and its internal mold core, and to transport the pipe and its internal mold core to the roller assembly 111.

[0070] Specifically, the first support assembly 118 may include a pusher 1181 and a second moving guide rail 1182. One end of the second moving guide rail 1182 is spaced apart from the roller assembly 111. The pusher 1181 is slidably disposed on the second moving guide rail 1182. When the pipe and its internal mold core are conveyed to the first support assembly 118, the pusher 1181 may first fix the pipe or its internal mold core to the pusher 1181, thereby fixing the pipe and mold core to the pusher 1181. Then, the pusher 1181 moves along the second moving guide rail 1182 to drive the pipe and its internal mold core closer to the roller assembly 111, so that the pipe and its internal mold core pass through the gap formed by the rollers 1111 in the roller assembly 111. The extension direction of the second moving guide rail 1182 may be parallel to the axial direction of the pipe, so that the pusher 1181 can drive the pipe to move along its axial direction along the second moving guide rail 1182.

[0071] The power assembly 112 then drives one of the pipe and the roller assembly 111 to move relative to the other, so that the roller 1111 can roll the pipe.

[0072] Through the cooperation of the pusher 1181 and the second moving guide rail 1182 in the first support assembly 118, the first support assembly 118 can transport the pipe and its internal mold core to the roller assembly 111, thereby realizing the automation of pipe transportation.

[0073] In some embodiments, when the power component 112 drives the pipe and its internal mold core to move, the second moving guide rail 1182 can be parallel to the first adjusting guide rail 1162 of the power component 112 to ensure that the pipe moves along its axial direction throughout the entire process. Then, when the pusher 1181 conveys the pipe and its internal mold core to the roller assembly 111 along the second moving guide rail 1182, the power component 1121 can move along the first adjusting guide rail 1162 close to the roller assembly 111 and fix the pipe and its internal mold core located at the roller assembly 111. Then the pusher 1181 can separate from the pipe and its internal mold core, and the power component 1121 drives the pipe and its internal mold core to move back and forth relative to the roller assembly 111 so that the roller 1111 can roll the pipe.

[0074] In some embodiments, the first support assembly 118 may also include a support base and a transmission component disposed on the support base, such as a transmission roller or a transmission belt. Subsequently, after the tube and its internal mold core are conveyed to the support base, the transmission component will convey the tube and its internal mold core to the roller assembly 111.

[0075] Optionally, the separation mechanism 12 includes a second support assembly 121 and a clamping assembly 122. The second support assembly 121 is used to receive the rolled pipe and its internal mold core. The clamping assembly 122 is used to clamp the pipe and drive the pipe away from the second support assembly 121 along the axial direction of the pipe. Alternatively, the clamping assembly 122 is used to clamp the mold core and drive the mold core away from the second support assembly 121 along the axial direction of the mold core, so as to separate the pipe from the mold core.

[0076] Specifically, such as Figure 1 The second support component 121 can be spaced apart from the power component 112, and the clamping component 122 can be spaced apart from the second support component 121. The second support component 121 receives the rolled tube and its internal mold core. Then, the clamping component 122 clamps the tube on the second support component 121 and moves the tube away from the second support component 121 along its axial direction, thus separating the tube from the mold core. It is understood that the mold core remains on the second support component 121 in this case. Alternatively, the clamping component 122 clamps the mold core on the second support component 121 and moves the mold core away from the second support component 121 along its axial direction, thus separating the tube from the mold core. It is understood that the tube remains on the second support component 121 in this case. Since the mold core passes through the tube, the axial direction of the mold core is parallel to the axial direction of the tube.

[0077] In some embodiments, the clamping assembly 122 may include a clamping member 1222 and a third moving guide rail 1221. One end of the third moving guide rail 1221 is spaced apart from the second support assembly 121. The clamping member 1222 is slidably disposed on the third moving guide rail 1221, and the extending direction of the third moving guide rail 1221 may be parallel to the axial direction of the tube placed on the second support assembly 121. The clamping member 1222 then moves closer to the second support assembly 121 along the third moving guide rail 1221. After clamping the tube or mold core, the clamping member 1222 can continue to move the tube or mold core away from the second support assembly 121 along the third moving guide rail 1221 along its axial direction, thereby separating the tube from the mold core. This achieves automatic separation of the tube from the mold core, improving the tube demolding efficiency.

[0078] In summary, in the demolding device 1 provided in this application embodiment, the pipe is rolled by the roller 1111 mechanism to release the contact extrusion stress between the pipe and the internal mold core, alleviate the residual internal stress generated during the pipe shaping process, and weaken the holding and locking effect of the pipe on the mold core, thereby reducing demolding friction and demolding difficulty; at the same time, the separation mechanism 12 separates the rolled pipe and the internal mold core, realizing the automation of the separation of the pipe and the mold core, and further improving demolding efficiency.

[0079] This application also provides a pipe processing production line (not shown), including at least one shaping device and a demolding device 1 arranged at intervals. The at least one shaping device is used to perform at least one shaping process on the pipe to be processed so that the pipe to be processed is shaped into a target pipe. The demolding device 1 is used to separate the target pipe and its internal mold core.

[0080] In this process, at least one shaping device performs at least one shaping process on the pipe to be processed, so that the pipe to be processed is shaped into the target pipe. Then, the demolding device 1 separates the target pipe and its internal mold core, realizing the full automation of pipe processing shaping and demolding, improving the processing efficiency of pipes and enhancing the practicality of the processing line.

[0081] Optionally, at least one shaping device includes a first shaping device and a second shaping device, the second shaping device being disposed downstream of the first shaping device. The first shaping device is used to shape the pipe to be processed into a preformed pipe in a moldless support manner, and the second shaping device is used to shape the preformed pipe into a target pipe under the support of a mold core.

[0082] The first shaping device performs coreless drawing and shaping of the pipe to be processed, changing its basic shape and contour. The second shaping device performs cored drawing and shaping of the pre-formed pipe, precision machining the contour of the pre-formed pipe to form the target pipe. The target pipe and its internal core are then separated by the demolding device 1. Through the cooperation of the first and second shaping devices, the pipe to be processed is gradually shaped into the target pipe, avoiding defects such as surface wrinkles, wall cracks, and uneven local deformation caused by excessive deformation of the pipe at one time, thus improving the processing accuracy of the production line.

[0083] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
