Description

Technical Field

[0001] This application relates to the field of door panel manufacturing technology, and in particular to a manufacturing process for a door panel that is resistant to deformation and cracking. Background Technology

[0002] In the furniture manufacturing industry, door panels, as a key component, are subject to significant advancements in manufacturing processes that profoundly impact the overall quality, functionality, and market competitiveness of furniture. With socio-economic development and rising aesthetic standards, consumers' demands for furniture have expanded beyond mere practicality, placing greater emphasis on aesthetics, durability, and stability. High-quality door panels not only enhance the overall quality of furniture but also extend its lifespan, providing consumers with a better user experience. Furthermore, advanced door panel manufacturing processes contribute to driving the furniture industry towards greater environmental friendliness, efficiency, and intelligence, thereby elevating the industry's technological level and economic benefits.

[0003] In the past, the following methods were commonly used in door panel production: Material selection was often based on experience, without fully considering the specific process requirements of each component, and different types of wood were not classified and stored according to size and material. Ordinary cutting tools were mostly used for cutting, making precise dimensional cuts difficult. Sanding operations might rely on simple sanding equipment, failing to guarantee an ideal flatness of the wood surface. For opening holes and slots in the door panels, manual tools or inaccurate machinery were often used, which could not meet complex process requirements. In the assembly and pressing stages, ordinary glue and simple pressure methods, such as pressing with heavy objects, were generally used, lacking the support of specialized equipment. Milling operations relied heavily on manual labor, making it difficult to control the accuracy and consistency of the shape. During assembly, there were no specialized auxiliary tooling; everything was done manually by workers, resulting in low efficiency and difficulty in guaranteeing assembly accuracy. Finally, staining and waxing were only simple treatments, offering limited improvement to the surface finish of the door panels.

[0004] Factors such as imprecise material selection, low cutting accuracy, poor sanding, and inaccurate hole and grooving can lead to deformation and cracking issues in the produced door panels. The lack of specialized equipment for assembly and pressing results in weak connections between different parts of the door panel, further exacerbating the risk of deformation and cracking. Insufficient milling and assembly precision also affects the overall quality and stability of the door panels, failing to meet market demands for high-quality door panels. Summary of the Invention

[0005] In order to improve the door panel's resistance to deformation and cracking, this application provides a manufacturing process for a door panel that is resistant to deformation and cracking.

[0006] This application provides a manufacturing process for a door panel designed to prevent deformation and cracking, employing the following technical solution: A manufacturing process for a door panel designed to prevent deformation and cracking includes the following steps: material selection, selecting materials according to the process requirements of each component of the door panel, and placing the selected wood into different types of cutting equipment according to size requirements and material; cutting, using the cutting equipment to cut the wood to size; sanding, using a sander to sand the cut wood; grooving, using a vertical milling machine to make holes and grooves in the parts of the door panel that need to be assembled according to process requirements; gluing, applying adhesive to the parts of the door panel that need to be assembled, and then conveying them to a high-frequency splicing machine for bonding and curing; gluing and pressing, applying adhesive to the parts of the door panel that need to be pressed, and then conveying them to a cold press for pressing; milling, milling the middle part of the door panel before assembly using a vertical milling machine according to the shape designed in the process; assembly, with a fixture fixed at the entrance of the high-frequency splicing machine, the fixture being used to assemble the various components of the door panel into one piece; polishing and waxing, polishing, waxing and coloring the surfaces of each component of the door panel.

[0007] By adopting the above technical solutions, suitable wood is selected for the production of each part of the door panel, providing a good foundation for subsequent production; the wood conforms to the dimensional specifications of each part of the door panel, ensuring the accuracy of each component; sanding makes the wood surface smooth, improving the quality of subsequent assembly and finishing; drilling and grooving provide accurate connection structures for the assembly of the door panel, facilitating subsequent splicing and assembly; gluing ensures that the various parts of the door panel are firmly spliced ​​together, enhancing the overall strength of the door panel. Glue pressing further improves the tightness of the bonding between the various parts of the door panel, ensuring the stability of the door panel. Milling gives the door panel the required appearance shape to meet design requirements; fixtures fixed at the entrance of the high-frequency splicing machine assemble the various components of the door panel into one piece, improving assembly efficiency and accuracy, ensuring the relative position and connection precision of each part of the door panel; sanding, waxing, and coloring the surfaces of each component of the door panel protect the door panel and improve its resistance to deformation and cracking.

[0008] Optionally, the door panel includes two vertical sides, two horizontal bars, and several door core modules. Each door core module includes a finger joint plate, two door core plugs, and two edge strips. The horizontal dimension of the finger joint plate and the two edge strips after being cut by a cutting device and the vertical dimension of the finger joint plate and the two door core plugs after being joined together are both no greater than 45mm.

[0009] By adopting the above technical solution, the door core panel is designed as a module with a horizontal dimension of no more than 45mm after the assembly of several finger-jointed boards and two edge strips, and a vertical dimension of no more than 45mm after the assembly of the finger-jointed boards and two door core end caps. This reduces the risk of deformation and cracking of the door panel caused by environmental factors. Smaller door core modules deform less under stress, and multiple modules can buffer each other, further improving the stability of the door panel. At the same time, smaller door core modules are easier to manufacture and control in terms of quality. Furthermore, if some modules malfunction, they can be replaced individually, reducing maintenance costs.

[0010] Optionally, the tooling includes a rotating component, a clamping component, a first pushing component, and a second pushing component. The rotating component is used to drive the assembled door panel to rotate, the clamping component is used to fix the vertical edge, the first pushing component is used to push the assembled door panel to slide along the width direction of the door panel, and the second pushing component is used to push the component to be assembled to slide towards the high-frequency splicing machine.

[0011] By adopting the above technical solutions, the rotating component can drive the assembled door panel to rotate, which facilitates the assembly operation of the door panel at different angles and positions, adapts to different assembly needs, and improves the flexibility and convenience of assembly; the clamping component is used to fix the vertical edge, which can ensure the stability of the vertical edge during the assembly process and prevent the vertical edge from shifting or shaking, thereby ensuring the accurate relative position of each component of the door panel and improving the assembly precision; the first pushing component pushes the assembled door panel to slide along the width direction of the door panel, which can enable the various parts of the door panel to accurately align and assemble in the width direction, which helps to achieve tight splicing in the width direction of the door panel; the second pushing component pushes the parts to be assembled to slide towards the high-frequency splicing machine, and after the parts to be assembled are assembled, they enter the high-frequency splicing machine for bonding and curing, improving the assembly efficiency and quality, and thus effectively improving the overall production quality and efficiency of the anti-deformation and cracking door panel.

[0012] Optionally, the rotating assembly includes a turntable, a worktable, and a driving component. The driving component is fixedly connected to the worktable. The turntable is rotatably connected to the upper surface of the worktable along a vertical axis. The driving component is used to drive the turntable to rotate. Both the clamping assembly and the first pushing assembly are provided in two sets and are evenly distributed along the circumference of the output shaft of the driving component.

[0013] By adopting the above technical solution, the driving component provides power support for the rotation of the turntable, enabling the turntable to rotate flexibly and drive the assembled door panels to rotate, facilitating assembly operations at different angles and positions. Both the clamping assembly and the first pushing assembly are provided in two sets and evenly distributed circumferentially along the output shaft of the driving component. This allows the door panels to be assembled at the two stations to be combined together under the action of the clamping assembly and the first pushing assembly, making the door panel assembly process more stable and precise, improving assembly efficiency and quality, and ultimately contributing to the production of door panels resistant to deformation and cracking.

[0014] Optionally, the clamping assembly includes two symmetrically arranged L-shaped plates, which are slidably connected to the upper surface of the turntable along a pushing direction parallel to that of the second pushing assembly. The two L-shaped plates slide synchronously in opposite directions, and the first pushing assembly is located between the two L-shaped plates.

[0015] By adopting the above technical solution, the L-shaped plate can be flexibly adjusted in position, precisely fixed in vertical direction, and ensure that the ends of the door panels to be assembled at the two clamped and fixed workstations that abut against the L-shaped plate are always on the same plane. The first pushing component can push the assembled door panel to slide along the width direction of the door panel, realizing coordinated operation in different directions during the door panel assembly process, improving the efficiency and accuracy of door panel assembly, and thus helping to produce door panels with better resistance to deformation and cracking.

[0016] Optionally, the first pushing component includes a plurality of first push plates and a plurality of first cylinders arranged along the arrangement direction of the two L-shaped plates. The cylinder body of the first cylinder is fixedly connected to the upper surface of the turntable. The first push plate is fixedly connected to the telescopic end of the first cylinder. A first vertical insert is vertically inserted between the vertical side and the door core plate. A plurality of insert rods are inserted along the vertical direction of the first vertical insert. The position of the first push plate corresponds to the position of the insert rods.

[0017] By adopting the above technical solution, when the first cylinder is activated, it can drive the first push plate to move. Since the position of the first push plate corresponds to the position of the insert rod, and a first vertical strip is vertically inserted between the vertical side and the door core panel, and several insert rods are inserted along the vertical direction of the first vertical strip, the first push plate can accurately act on the insert rods when it moves, so that the insert rods are better fixed on the first vertical strip, thereby enhancing the connection stability between the vertical side and the door core panel, improving the firmness of the door panel assembly, and making the produced door panel less prone to deformation and cracking.

[0018] Optionally, the second pushing component includes a second push plate, a screw, and a drive motor. A bracket is fixedly provided on the upper surface of the worktable. The drive motor is fixedly connected to the bracket and coaxially fixedly connected to the screw. The second push plate is threadedly connected to the screw. The drive motor drives the second push plate to slide along the arrangement direction parallel to the two L-shaped plates.

[0019] By adopting the above technical solution, when the drive motor is working, it can drive the second push plate to slide along the arrangement direction parallel to the two L-shaped plates, which can accurately push the parts to be assembled to move towards the high-frequency splicing machine, realizing the precise delivery of the parts to be assembled. This is conducive to improving the assembly accuracy and efficiency of the various components of the door panel, thereby improving the overall production quality of the anti-deformation and cracking door panel.

[0020] Optionally, the L-shaped plate is fixedly connected to a second cylinder, and the telescopic end of the second cylinder is fixedly connected to a third push plate. The vertical side includes a vertical inner core, an inner side plate, an outer side plate, and two door edge plugs. The third push plate corresponds to the position of the door edge plugs.

[0021] By adopting the above technical solution, the second cylinder fixed on the L-shaped plate can drive the third push plate connected to the telescopic end to move. Since the third push plate corresponds to the position of the door edge plug on the vertical side, the door edge plug can be accurately pushed during the door panel assembly process, so that the vertical inner core, inner side plate, outer side plate and door edge plug on the vertical side can be better assembled together, improving the accuracy and stability of the vertical side assembly, thereby improving the quality of the entire door panel assembly and helping to produce door panels with better anti-deformation and cracking performance.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Ensure the selection of suitable wood for each part of the door panel, providing a solid foundation for subsequent production; ensure the wood conforms to the dimensional specifications of each part of the door panel, guaranteeing the accuracy of each component; sanding smooths the wood surface, improving the quality of subsequent assembly and finishing; drilling and grooving provide accurate connection structures for door panel assembly, facilitating subsequent splicing and assembly; gluing firmly joins the various parts of the door panel together, enhancing its overall strength. Adhesive pressing further improves the tightness of the bond between the various parts of the door panel, ensuring its stability. Milling gives the door panel the required appearance shape to meet design requirements; fixtures fixed at the entrance of the high-frequency splicing machine assemble the various components of the door panel into a single unit, improving assembly efficiency and accuracy, ensuring the relative position and connection precision of each part; sanding, waxing, and coloring the surfaces of each component of the door panel protects it and improves its resistance to deformation and cracking. 2. Designing the door core panel as a module with a horizontal dimension of no more than 45mm after splicing several finger-jointed boards and two edge strips, and a vertical dimension of no more than 45mm after splicing the finger-jointed boards and two door core end caps, reduces the risk of deformation and cracking of the door panel caused by environmental factors. Smaller door core modules exhibit less deformation under stress, and multiple modules can buffer each other, further improving the stability of the door panel. Simultaneously, smaller door core modules are easier to manufacture and control in terms of quality, and can be replaced individually if some modules malfunction, reducing maintenance costs. 3. The rotating component can drive the assembled door panel to rotate, facilitating assembly operations at different angles and positions, adapting to different assembly needs, and improving assembly flexibility and convenience; the clamping component is used to fix the vertical edge, ensuring the stability of the vertical edge during the assembly process, preventing displacement or shaking of the vertical edge, thereby ensuring the accurate relative position of each component of the door panel and improving assembly precision; the first pushing component pushes the assembled door panel to slide along the width direction of the door panel, enabling accurate docking and assembly of each part of the door panel in the width direction, which helps to achieve tight splicing in the width direction of the door panel; the second pushing component pushes the parts to be assembled to slide towards the high-frequency splicing machine, and after the parts to be assembled are completed, they enter the high-frequency splicing machine for bonding and curing, improving assembly efficiency and quality, and thus effectively improving the overall production quality and efficiency of anti-deformation and cracking door panels.

[0033] The present application will be further described in detail below with reference to all the accompanying drawings.

[0034] This application discloses a manufacturing process for a door panel designed to prevent deformation and cracking.

[0035] Reference Figures 1-8 A production process for anti-deformation and cracking door panels includes steps such as material selection, blanking, sanding, grooving, gluing, gluing and pressing, milling, assembly, coloring and waxing. Each step works closely together to achieve efficient production of anti-deformation and cracking door panels, thereby improving the quality and performance of the door panels.

[0036] In the material selection process, materials are chosen based on the process requirements of each component of the door panel. The door panel includes a core panel 1, two vertical edges 2, and two horizontal rails 3. The vertical edges 2 include a vertical inner core 21, an inner edge panel 24, an outer edge panel 25, two door edge end caps 22, and two outer outer edge panels 23. The core panel 11 includes a finger-jointed board 111, two core end caps 112, two edge strips 113, two horizontal pull plates 114, and two panel 115. The horizontal rails 3 include a horizontal inner core 31, two outer horizontal side panels, and two horizontal end caps 32. The vertical inner core 21 can generally be made of wood, such as oak or cedar, which has a certain strength and toughness. Some new composite materials can also be used to improve its stability. The core end caps 112 and edge strips 113 are also usually made of wood, and their materials can be the same as or similar to those of the vertical inner core 21. Finger-jointed boards 111, cross bracing 114, top panel 115, outer side panels 23, and outer transverse side panels can be made of harder wood, such as high-density fiberboard. The selected timber is placed according to size requirements and material properties at different cutting machines, including table saws, frame saws, and multi-blade saws. Different cutting machines are suitable for timber of different sizes and materials. For example, table saws are suitable for precise cutting of larger timber, frame saws are more suitable for cutting timber with special shapes, and multi-blade saws can improve cutting efficiency.

[0037] In the material preparation step, the wood is cut to size using a cutting device. For the core panel 1, which includes several core modules 11, the horizontal dimension of the finger-jointed board 111 and the two edge strips 113 after being cut by the cutting device, and the vertical dimension of the finger-jointed board 111 and the two core end caps 112 after being joined together, are all no greater than 45mm. This design can reduce the risk of deformation and cracking of the overall door panel caused by environmental factors. The smaller core module 11 has a relatively smaller deformation when subjected to stress, and multiple core modules 11 can buffer each other, further improving the stability of the door panel.

[0038] The sanding step involves using a sander to sand the cut wood. Sanding makes the wood surface smoother, removing burrs and unevenness, providing a good foundation for subsequent gluing and surface treatment. Sanders are available in different models and belt grits; choose the appropriate sander and grit based on the wood's texture and surface requirements.

[0039] In the grooving step, a vertical milling machine is used to drill holes and grooves in the parts of the door panel that need to be assembled, according to the process requirements. Several grooves 211 are sequentially cut along the vertical direction on the vertical end face of the vertical inner core 21. The grooves 211 penetrate horizontally, and their depth is no greater than half the thickness of the vertical inner core 21. The grooves 211 at both ends of the vertical inner core 21 are staggered vertically. The design of the grooves 211 further enhances the door panel's ability to disperse and release stress. When the door panel experiences stress due to environmental factors, the grooves 211 can act as a stress buffer zone, allowing the stress to be released at the grooves 211, preventing stress concentration at a single point that could lead to door panel deformation or cracking. Simultaneously, using a vertical milling machine, a first groove 241 is formed at the end of the inner side plate 24 near the core plate 1, a second groove 1131 is formed at the end of the side strip 113 away from the finger joint plate 111, and a third groove 33 is formed at the end of the horizontal plug 32 near the inner side plate 24. The shape of the first vertical insert 41 matches the shape of the first groove 241, the second groove 1131, and the third groove 33. A third groove 33 is formed at the end of the horizontal block 3 near the core module 11, and a fourth groove 1 is formed at the end of the core plug 112 away from the finger joint plate 111. 121, the shape of the horizontal insert 51 matches the shape of the third slide groove 33 and the fourth slide groove 1121; a first slot 1111 is opened on the upper end surface of the finger joint plate 111, a second slot 1132 is opened on the end of the edge strip 113 near the finger joint plate 111, and a third slot 1122 is opened on the end of the door core plug 112 near the finger joint plate 111; the connecting block 121 is slotted so that a vertical through slot is opened on the end near the outer side plate 25, and the through slot includes a rectangular slot 1211 and an irregular slot 1212 from top to bottom.

[0040] The gluing process involves applying glue to the adjacent sidewalls of the vertical inner core 21, inner side panel 24, outer side panel 25, and two door edge end caps 22 before joining them. Before applying glue, the end of the inner core near the door edge end cap 22 needs to be waxed to prevent glue from penetrating the wood and affecting its properties. Next, apply glue to the adjacent sidewalls of the finger-jointed board 111, two door core end caps 112, and two edge strips 113 before joining them. Again, the end of the finger-jointed board 111 near the door core end cap 112 needs to be waxed before applying glue. Finally, apply glue to the adjacent sidewalls of the horizontal inner core 31 and two horizontal end caps 32 before joining them. The choice of glue depends on the type of wood and the intended use environment; generally, environmentally friendly woodworking glue can be used.

[0041] In the adhesive pressing step, adhesive is applied to the adjacent sidewalls of the glued vertical inner core 21, inner side plate 24, outer side plate 25, and two door edge plugs 22, and then pressed together. Adhesive is also applied to the adjacent sidewalls of the glued finger joint plate 111, two horizontal pull plates 114, and two panel plates 115, and then they are joined together. Finally, adhesive is applied to the adjacent sidewalls of the glued horizontal inner core 31, two horizontal plugs 32, and two outer horizontal side plates, and then they are pressed together. The pressing operation can use a cold press or a hot press; the appropriate pressing method and pressing time should be selected based on the characteristics of the adhesive and the process requirements.

[0042] In the milling step, according to the shape designed in the process, a vertical milling machine is used to mill the door core plug 112 and the ends of the two side strips 113 away from the finger joint plate 111. Milling allows the door core module 11 to better fit the shape formed between the inner side plate 24 and the crossbar 3, improving the overall aesthetics and assembly accuracy of the door panel.

[0043] Reference Figure 9 The assembly process involves assembling the door panel 1, two vertical edges 2, and two horizontal supports 3 into a single unit using a tooling assembly. The tooling assembly includes a rotating component 6, a clamping component 7, a first pushing component 8, and a second pushing component 9. The rotating component 6, used to drive the assembled door panel to rotate, includes a turntable 61, a worktable 62, and a driving component 63. The driving component 63 is fixedly connected to the worktable 62. The turntable 61 is rotatably connected to the upper surface of the worktable 62 along a vertical axis. The driving component 63, which can be a motor or other power device, drives the turntable 61 to rotate. The clamping component 7, used to fix the vertical edges 2, includes two symmetrically arranged L-shaped plates. The L-shaped plates are slidably connected to the upper surface of the turntable 61 along a pushing direction parallel to the second pushing component 9. The two L-shaped plates slide synchronously in opposite directions. The first pushing component 8 is located between the two L-shaped plates. Both L-shaped plates are fixedly connected to a second cylinder 83. The telescopic end of the second cylinder 83 is fixedly connected to a third push plate 84, which corresponds to the position of the door edge plug 22. The vertical side 2 can be fixed by adjusting the position of the two L-shaped plates. A motor is fixed to the upper surface of the turntable 61. The motor drives a bidirectional lead screw to rotate. The bidirectional lead screw is threadedly connected to the two L-shaped plates respectively, thereby driving the two L-shaped plates to slide synchronously in opposite directions and fix the vertical side 2.

[0044] Reference Figure 9The first pushing component 8 is used to push the assembled door panel to slide along the width direction of the door panel. The first pushing component 8 is located between two L-shaped plates. The first pushing component 8 includes several first pushing plates 81 and several first cylinders 82 arranged along the arrangement direction of the two L-shaped plates. The cylinder body of the first cylinder 82 is fixedly connected to the upper end face of the turntable 61. The first pushing plate 81 is fixedly connected to the telescopic end of the first cylinder 82. The position of the first pushing plate 81 corresponds to the position of the insertion rod 42. The first cylinder 82 drives the insertion rod 42 to pass through the vertical inner core 21, the inner side plate 24 and the first vertical insertion strip 41 in sequence and then insert it into the connecting block 121 by pushing the first pushing plate 81.

[0045] Reference Figure 9 The second pushing component 9 is used to push the parts to be assembled towards the high-frequency splicing machine. It includes a second push plate 91, a screw 93, and a drive motor 92. A bracket 94 is fixedly mounted on the upper surface of the worktable 62. The drive motor 92 is fixedly connected to the bracket 94 and coaxially fixedly connected to the screw 93. The second push plate 91 is threadedly connected to the screw 93. The drive motor 92 drives the second push plate 91 to push the door core panel 1, the horizontal plug 32, and the second vertical insert 52 to slide along the arrangement direction parallel to the two L-shaped panels. After assembly, the door panel is pushed into the high-frequency splicing machine for glue bonding.

[0046] Reference Figure 9 During assembly, the inner side plate 24 with the first vertical insert 41 inserted is first glued to the vertical inner core 21 and the door edge plug 22. The glued inner side plate 24, vertical inner core 21, and door edge plug 22 are then placed between two L-shaped plates for fixation. The first horizontal plug 32, several door core modules 11, and the second horizontal plug 32 are sequentially installed on the end of the first vertical insert 41 away from the inner side plate 24. The second push plate 91 is pushed by the drive motor 92 to drive these components to slide. Then, the horizontal insert 51 is inserted to fix the horizontal plug 32, several door core modules 11, and another horizontal plug 32 in sequence. The first horizontal inner core 31 is inserted at the horizontal insert 51 of the first horizontal plug 32. When installing the door core module 11, first assemble the door core module 11, then place the connecting block 121 into the first slot 1111 of the finger joint plate 111, and then the finger joint plate 111, the door core plug 112, and the edge strip 113 are glued together to surround the connecting block 121.

[0047] The steps of polishing and waxing involve sanding, waxing, and coloring the surface of the door panel. Sanding makes the surface smoother, waxing improves the water resistance, and coloring allows users to choose suitable colors according to their needs and preferences, enhancing the aesthetics of the door panel.

[0048] Reference Figure 9After waxing both ends of the vertical inner core 21, the door edge plug 22 is glued to the vertical inner core 21. The inner side plate 24 with the first vertical insert 41 inserted is glued to the vertical inner core 21 and the door edge plug 22. The glued inner side plate 24, the vertical inner core 21, and the door edge plug 22 are placed between two L-shaped plates. The positions of the two L-shaped plates are adjusted to fix the three components. The side of the two L-shaped plates that is far apart from each other blocks the through opening of the first sliding groove 241 of the inner side plate 24. The second cylinder 83 pushes the third push plate 84 to abut against the door edge plug 22. The first horizontal plug 32, several door core modules 11, and the second horizontal plug 32 are sequentially installed on the end of the first vertical insert 41 away from the inner side plate 24. The first horizontal plug 32, several door core modules 11, and the second horizontal plug 32 are slid by the second push plate 91 driven by the drive motor 92. Then, the horizontal insert 51 is inserted to fix the horizontal plug 32, several door core modules 11, and the other horizontal plug 32 in sequence. The first horizontal inner core 31 is inserted at the horizontal insert 51 of the first horizontal plug 32.

[0049] During the installation of the door core module 11, the door core module 11 is assembled first. After the connecting block 121 is placed into the first slot 1111 of the finger joint plate 111, the finger joint plate 111, the door core plug 112, and the edge strip 113 are glued together to surround the connecting block 121.

[0050] Reference Figure 9 Subsequently, the first cylinder 82 pushes the insert rod 42 through the first push plate 81, passing it sequentially through the vertical inner core 21, the inner side plate 24, and the first vertical insert strip 41 before inserting it into the connecting block 121. It continues to push the door core module 11, and the irregular block 421 of the insert rod 42 slides into the irregular groove 1212. The first cylinder 82 and the second cylinder 83 retract, and the glued outer side plate 25 is placed between the first push plate 81 and the third push plate 84 and the vertical inner core 21. The first cylinder 82 and the second cylinder 83 push the outer side plate 25 to fit with the vertical inner core 21. Then, the turntable 61 is rotated, and the other half of the door panel is installed using the same steps. After both half of the door panel is assembled, the first cylinder 82 and the second cylinder 83 on both sides of the two half of the door panel extend simultaneously and fit together. The second push plate 91 is pushed by the drive motor 92 to drive the second vertical insert strip 52 to pass sequentially through the first horizontal inner core 31, the side strips 113 of several door core modules 11, and the second horizontal inner core 31. The drive motor 92 continues to push the laminated door panel into the high-frequency splicing machine. After exiting the high-frequency splicing machine, glue is applied to the outside of the vertical inner core 21 to laminate the outer outer panel 23, glue is applied to the outside of the horizontal inner core 31 to laminate the outer horizontal side panel, and glue is applied to the outside of the finger joint plate 111 to laminate the horizontal pull plate 114 and the table plate 115 in sequence. Then it is conveyed to the cold press for pressing.

[0051] The implementation principle of the manufacturing process for an anti-deformation and cracking door panel according to this application embodiment is as follows: Through the coordinated operation of the above-mentioned multiple steps, attention is paid to the performance and material matching of each component from the material selection stage. Steps such as blanking, sanding, and grooving lay the foundation for subsequent assembly and performance improvement. The glue splicing and glue pressing steps ensure the firmness of the connection between each component, and the milling step improves the assembly accuracy and aesthetics of the door panel. The use of tooling makes the assembly process more efficient and precise. The rotating component 6, clamping component 7, first pushing component 8, and second pushing component 9 cooperate with each other to achieve accurate installation of each component of the door panel. The grooving 211, the setting of different texture directions, and the design of the door core module 11 all help to disperse the stress on the door panel and reduce the risk of deformation and cracking caused by stress concentration. Finally, the aesthetics and waterproof performance of the door panel are further improved by wiping and waxing. The entire manufacturing process effectively solves the problem of easy deformation and cracking of traditional door panels, improves the quality and performance of the door panel, reduces production costs, and also performs well in terms of environmental protection and aesthetics, showing significant improvement and enhancement compared to traditional methods.

[0052] 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.
