Description

Technical Field

[0001] The invention relates to the technical field of layered composite material manufacturing, in particular to a forming device for processing carbon fiber composite plates. Background Art

[0002] In existing technology, the layered structure of carbon fiber composite sheets is primarily formed using a hot pressing process involving a male (upper) and female (lower) molds. The process involves sequentially applying a release agent to the lower mold surface, laying down multiple layers of carbon fiber prepreg, closing the molds and heating and curing them (electric heating elements are built into both the upper and lower molds), and then cooling and opening the molds. After a single molding cycle, the product must be removed from the lower mold and thoroughly cleaned before re-initiating the release agent application and prepreg laying process to achieve continuous lamination.

[0003] However, this process has significant drawbacks: the lamination process is frequently interrupted. Release agent application, prepreg placement, and cleaning operations all require the fixed lower mold, resulting in prolonged mold occupancy. The heating unit remains idle during this waiting period, leading to low equipment utilization and fluctuations in interlayer bonding quality due to the increased manual operation. Especially in large-scale production, the serialized operation process severely restricts the output efficiency of layered composite panels. A solution that allows for rapid lower mold replacement and parallel prepreg placement and hot pressing is urgently needed. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that the existing carbon fiber composite sheet forming device needs to serially complete the release agent coating, material laying and cleaning operations on the lower mold, resulting in a long waiting time at the hot pressing station, which seriously restricts the lamination production efficiency and equipment utilization.

A strip groove corresponding to the chain is opened on the surface of the extension platform, and one section of the chain is fixed to the lower surface of the first lower die base or the second lower die base through a linking piece.

[0008] In a preferred embodiment of the carbon fiber composite plate forming device of the present invention, the bottom plate of the first lower die holder and the bottom plate of the second lower die holder are fixed by a connecting plate. The lower surface of the bottom plate of the first lower mold base or the second lower mold base slides along the upper surfaces of the base and the extension platform.

[0009] In a preferred embodiment of the forming device for processing carbon fiber composite panels according to the present invention: a first limiting slide groove perpendicular to the moving direction of the lower mold base component is provided on the upper surface of the base plate, two first limiting slide grooves are arranged in parallel, and a plurality of limiting slide feet are provided on the lower surface of the intermediate plate, and each limiting slide foot slides in the corresponding first limiting slide groove.

[0010] In a preferred embodiment of the forming device for processing carbon fiber composite panels of the present invention: three second limiting slide grooves are opened on the upper surface of the intermediate plate, the second limiting slide grooves are consistent with the moving direction of the lower die base component, and the sliding feet used for the lower surface of the lower die are detachable and installed.

[0011] In a preferred embodiment of the carbon fiber composite plate forming device of the present invention, two mounting holes are provided on the intermediate plate, corresponding to the two first limiting sliding grooves respectively. The first power connection piece is detachably mounted in the mounting hole. The upper end of the first power connection member is located in the middle of the three second limiting sliding grooves, and the lower end is in the first limiting sliding groove.

[0012] In a preferred embodiment of the carbon fiber composite sheet forming device of the present invention, the first power connection member includes a T-shaped shell at the lower end and a column at the upper end, and extrusion feet are provided on both symmetrical sides of the T-shaped shell. The outer end of the extrusion foot is arc-shaped and is provided with a spring for pulling the extrusion foot outward. A vertical through hole is provided inside the T-shaped shell and the column, a connecting rod is provided in the through hole, an outer wall of the connecting rod is provided with an inclined groove, and the inner end of the extrusion foot is located in the inclined groove for controlling the lifting of the connecting rod.

[0013] In a preferred embodiment of the carbon fiber composite sheet forming device of the present invention, a power connection piece is provided in the first limiting chute, a circular cavity with an enlarged diameter is provided at the position where the node piece is provided, and the outer end of the extrusion foot is in contact with the inner wall of the circular cavity.

[0015] The beneficial effects of the present invention are as follows: Through the coordinated design of a dual-station translation mechanism and a modular quick-change structure, this device solves the problem of equipment idleness caused by serial operation of lower molds in traditional carbon fiber laminate production. The first and second lower mold bases, arranged in parallel, are synchronously driven by a dual-chain translation mechanism, enabling instantaneous switching between processing and material preparation stations. The sliding design of the intermediate plate perpendicular to the translation direction, combined with the rapid assembly and disassembly mechanism of the lower die, enables parallel operation of material preparation and hot pressing curing, completely shifting the mold preparation time, which traditionally accounts for the production cycle, outside the equipment cycle, thereby increasing the production capacity of a single device.

[0016] To address the potential safety hazards of replacing live modules, a power-off mechanism is designed to provide a safety safeguard. When the middle plate, carrying the first contact, slides into the expanded circular cavity of the base's retaining slot, the spring-loaded squeeze foot expands outward, pushing the contact bar down and into contact with the contact strip. During removal, the slot walls compress the squeeze foot inward, causing the contact bar to rise and disconnect power. This process automatically achieves electrical isolation before the modules are physically separated, eliminating the operational risks of traditional plug-in connections while minimizing module changeover time.

[0019] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0020] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0021] Reference Figures 1-11 The present embodiment provides a forming device for processing carbon fiber composite panels, which is used for continuously producing carbon fiber laminates, including an upper mold base component 1, the bottom of which is equipped with an upper punch 41, and the upper punch 41 has a built-in heating element; a lower mold base component 2, including a first lower mold base 21 and a second lower mold base 22 arranged in parallel, which are driven alternately by a translation mechanism 28 to enter the processing station directly below the upper mold base component 1; wherein the first lower mold base 21 and the second lower mold base 22 both include a base 23, a bottom plate 24 horizontally arranged on the base 23, and the bottom plate 24 is fixedly connected to the translation mechanism 28; an intermediate plate 25 detachably mounted on the bottom plate 24, and its moving direction is perpendicular to the translation direction of the bottom plate 24; a lower die 42 is arranged on the intermediate plate 25; a first power connection part 26 is provided at the bottom of the intermediate plate 25 for powering on / off the heating element in the lower die 42.

[0022] In the present application, continuous production is achieved by alternating operation of two lower die base components 2, wherein the upper die base component 1 serves as a fixed processing unit, and the upper punch 41 at its bottom has a built-in heating element for hot pressing and curing, and the lower die base component 2 adopts a first lower die base 21 and a second lower die base 22 arranged in parallel, which are driven by a translation mechanism 28 to achieve work station switching, and each lower die base adopts a layered design: the base 23 provides support, the bottom plate 24 is fixed to the translation mechanism 28 to achieve horizontal movement, and the middle plate 25 can slide perpendicular to the translation direction to complete rapid replacement, and the lower die 42 installed on the middle plate 25 is used to carry materials, and its built-in heating element cooperates with the first power connection 26 at the bottom of the middle plate 25 and the second power connection 29 on the lower die 42 to achieve power control.

[0023] When one of the lower die holders is in the processing station for hot pressing, the other lower die holder can be moved out for material replacement operation. The lower die 42 can be quickly disassembled and installed by sliding the intermediate plate 25. At the same time, the first power connection part 26 located on the intermediate plate 25 automatically completes the power-off protection of the lower die 42. This design effectively solves the low efficiency problem caused by serial operation of traditional equipment and realizes parallel operation of processing and material preparation.

[0024] Extension platforms 27, with flush top surfaces, are symmetrically positioned on the left and right sides of the base 23. Two translation mechanisms 28 are installed below each extension platform 27. When one lower die base is in the processing station, the other lower die base rests on the extension platform 27. The bottom plate 24 of the first lower die base 21 and the bottom plate 24 of the second lower die base 22 are secured by a connecting plate 285. The bottom surface of the bottom plate 24 of the first lower die base 21 or the second lower die base 22 slides along the top surface of the base 23 and the extension platforms 27.

[0025] The lower die base component 2 adopts a symmetrical design. Horizontally extending extension platforms 27 are installed on both sides of the base 23 to support the lower die. The upper surfaces of the two extension platforms 27 are flush with the upper surface of the base 23. The translation mechanism 28 utilizes a symmetrical dual-drive layout, with two sets installed below the extension platforms 27 on either side. The base plates 24 of the first and second lower die bases 21 and 22 are interconnected and fixed by a rigid connecting plate 285, forming a single-piece structure. During operation, the translation mechanism 28 drives the base plates 24 of the two lower die bases to slide smoothly along the upper surfaces of the base 23 and the extension platforms 27, ensuring the synchronization and stability of the translational motion. This symmetrical arrangement of the extension platforms 27 not only provides installation space for the translation mechanism 28 but also serves as a guide reference surface for the sliding of the base plates 24, enabling the entire lower die base system to perform precise alternating displacements. Furthermore, ball bearings or other devices can be installed on the lower surface of the base plates 24 or the upper surfaces of the base 23 and the extension platforms 27 to reduce friction.

[0026] The translation mechanism 28 includes two groups of chains 281 installed in parallel on both sides of the lower surface of each extension platform 27. A sprocket 282 is provided at both ends of each chain 281, and the two sprockets 282 on the side close to the base 23 are connected in series by the output shaft of the same motor. A strip groove 283 corresponding to the chain 281 is opened on the surface of the extension platform 27, and one section of the chain 281 is fixed to the lower surface of the first lower mold base 21 or the second lower mold base 22 through a linking plate 284.

[0027] The translation mechanism 28 utilizes a dual-chain 281 synchronous drive design. Two sets of parallel chains 281 are arranged below the extension platforms 27 on either side of the base 23. Each set of chains 281 is equipped with a sprocket 282 at each end. The two sprockets 282 on the side closest to the base 23 are coaxially linked by a common motor output shaft. This allows the motor on each side to control the synchronous movement of the two parallel chains 281 on the same side. The extension platforms 27 have a strip-shaped through-slot through which the chains 281 are connected to the lower die base plate 24. Specifically, specific segments of the chains 281 are fixed to the lower surface of the lower die base plate 24 via linking plates 284. When the motor drives the sprockets 282 to rotate, the chains 281 drive the fixedly connected lower die base to achieve precise translational motion. This symmetrical arrangement of the dual chains 281 ensures synchronization and stability during the movement of the two lower die base components 2.

[0028] The top surface of the bottom plate 24 is provided with two first limiting grooves 241 perpendicular to the direction of movement of the lower die base component 2. The bottom surface of the intermediate plate 25 is provided with multiple limiting legs 251, each of which slides within a corresponding first limiting groove 241. The top surface of the intermediate plate 25 is provided with three second limiting grooves 252, which are aligned with the direction of movement of the lower die base component 2 and are used to detachably mount the legs on the lower surface of the lower die 42.

[0029] The positioning guide of the present application adopts a multi-stage slide structure design, in which two parallel first limit slides 241 are processed on the upper surface of the bottom plate 24, and their extension direction is perpendicular to the overall movement direction of the lower die base component 2. This allows staff to stand on the left and right sides of the production line to quickly switch the intermediate plate 25 and the lower die 42 removed by the translation mechanism 28 as a whole. One side imports the new intermediate plate 25 and the lower die 42, and the other side exports the old intermediate plate 25 and the lower die 42, providing a first method of disassembling the lower die 42. A plurality of guide slides are correspondingly provided at the bottom of the intermediate plate 25. These slides are precisely embedded in the first limit slide 241 of the bottom plate 24 to ensure that the intermediate plate 25 slides smoothly along the predetermined trajectory when replaced.

[0030] The upper surface of the middle plate 25 is provided with three parallel second limiting runners 252, which run in the same direction as the translation of the lower die base. This facilitates the independent removal of the lower die 42 from the middle plate 25, providing a second method for removing the lower die 42. The bottom of the lower die 42 is also provided with removable positioning feet. These feet cooperate with the second limiting runners 252 of the middle plate 25, ensuring the precise positioning of the lower die 42 while facilitating quick assembly and replacement.

[0031] This multi-level slide guide enables multiple disassembly of the lower concave die 42. When a problem occurs in one of them, another one can be promptly supplemented to avoid affecting production. Among them, the first disassembly method requires the disassembly of the lower die 42 and the middle plate 25 together, which ensures that the connection between the lower die 42 and the middle plate 25 is always stationary, and only the middle plate 25 and the bottom plate 24 are quickly switched, avoiding the wear of the lower die 42 caused by frequent switching (because the importance and manufacturing difficulty of the lower die 42 are higher than the middle plate 25, the wear of the middle plate 25 is easier to replace and accept). At the same time, since its moving direction is perpendicular to the movement direction of the translation mechanism 28, it can provide two left and right positions, realizing the synchronous movement of loading and unloading on one side, thereby improving work efficiency; the second disassembly method requires the rapid disassembly of the lower die 42 separately, but the lower die 42 can only have a single station for loading and unloading, which requires unloading before loading, which takes longer time than the first method. Therefore, as a backup solution, the entire multi-level guide ensures the position accuracy and stability of each component during the two quick disassembly processes.

[0032] To overcome the efficiency bottleneck of traditional carbon fiber sheet forming equipment, this device utilizes a dual-station collaborative operation mode. Key to this design is the simultaneous loading and unloading of materials: while one station is installing the intermediate plate 25 and lower die 42, the other station can simultaneously dismantle the old die. This parallel operation significantly reduces production cycle time, but it also presents new technical challenges. Because the heating element within the lower die 42 requires continuous power, using traditional plug-in power connections would be cumbersome and negate the efficiency advantages of the dual-station design. To address this, this solution has developed a new power connection method compatible with the rapid disassembly process. Specifically, two mounting holes 253 are defined in the intermediate plate 25, corresponding to the two first retaining slots 241. A first power connector 26 is removably mounted within these mounting holes 253. The upper end of the first power connector 26 is located in the middle of the three second retaining slots 252, while the lower end is in the first retaining slot 241.

[0033] The middle plate 25 has two mounting holes 253 corresponding to the first limiting slots 241 of the bottom plate 24. The first electrical connector 26 is removably secured within the mounting holes 253. Its upper extension lies in the center of the three second limiting slots 252 of the middle plate 25, while its lower portion extends into the first limiting slots 241 of the bottom plate 24. This arrangement allows the first electrical connector 26 to penetrate the upper and lower surfaces of the middle plate 25, ensuring reliable power supply to the heating element of the lower die 42 while maintaining relative sliding movement between the middle plate 25 and the bottom plate 24. The removable nature of the first electrical connector 26 facilitates maintenance and replacement, while its placement through the central slot ensures precise electrical connection with the lower die 42 while avoiding interference with other slot structures. The entire electrical connection works in conjunction with mechanical guides, ensuring both electrical safety and ease of operation while enabling quick replacement.

[0034] The first power connection member 26 and the second power connection member 29 both include a T-shaped shell 261 at the lower end and a column 262 at the upper end. Extrusion feet 263 are provided on both symmetrical sides of the T-shaped shell 261. The outer end of the extrusion foot 263 is arc-shaped, and a spring 264 is provided for pulling the extrusion foot 263 outward. A vertical through hole 265 is provided inside the T-shaped shell 261 and the column 262. A power connection rod 266 is provided in the through hole 265. The outer wall of the power connection rod 266 is provided with an inclined groove. The inner end of the extrusion foot 263 is located in the inclined groove for controlling the lifting and lowering of the power connection rod 266. A power connection piece 267 is provided in the first limiting slide groove 241. A circular cavity 268 with an enlarged diameter is provided in the first limiting slide groove 241 at the position where the power connection piece 267 is provided. The outer end of the extrusion foot 263 fits into the inner wall of the circular cavity 268. The two power connection pieces 267 correspond to the neutral wire and the live wire respectively. The lower end of the power connection rod 266 contacts the power connection piece 267. The upper end of the power connection rod 266 is provided with a power connection port 269. The lower concave mold 42 is also provided with a second power connection piece 29. The second power connection piece 29 of the lower concave mold 42 is plugged into the power connection port 269.

[0035] Both the first and second power connectors 26 and 29 utilize a mechanically linked power connection design. Their core components include a T-shaped shell 261 and an upper column 262. Retractable extrusion feet 263 are symmetrically mounted on either side of the T-shaped shell 261. The outer ends of the extrusion feet 263 utilize an arc-shaped structure to ensure smooth sliding and, in conjunction with a spring 264, automatically reset. A vertical channel runs through the T-shaped shell 261 and column 262, housing a vertically movable connecting rod 266. The connecting rod 266 and the extrusion feet 263 are controlled by an inclined groove. When the first power connector 26 moves to the position of the connecting plate 267, the expanded circular cavity 268 of the first limiting chute 241 causes the extrusion feet 263 to expand outward under the action of the spring 264, pushing the connecting rod 266 downward to contact the connecting plate 267 within the chute, thereby conducting electricity. When the first power connector 26 moves out of this position, the chute wall compresses the extrusion feet 263 inward, driving the connecting rod 266 upward to disconnect the power. The top of the connecting rod 266 is equipped with a power connection port 269, which quickly connects to the plug of the connecting piece 26. The upwardly protruding bottom wall of the power connection port 269 contacts the protrusion at the bottom of the connecting rod 266, ensuring reliable power supply to the heating element. This design organically combines mechanical movement with electrical connection, ensuring safety while enabling rapid assembly and disassembly under power.

[0036] It should be noted that the electrical connection parts are provided on both the middle plate 25 and the lower concave mold 42, and the lower end of the connecting rod 266 of the second electrical connection part 29 of the lower concave mold 42 will be inserted into the upper end of the T-shaped shell 261 of the first electrical connection part 26 of the middle plate 25, and contact the electrical port 269 on the upper end of the connecting rod 266 in the T-shaped shell 261, thereby connecting the entire circuit.

[0037] Specifically, during installation, the first power connection member 26 of the middle plate 25 slides along the first limiting slide groove 241 along with the limiting slide foot 251, wherein the cross-sectional area of ​​the T-shaped shell 261 of the first power connection member 26 is the same as the cross-sectional area of ​​the limiting slide foot 251, and the first limiting slide groove 241 is provided with a downward groove on the lower surface of the position where the power connection piece 267 is provided. The power connection piece 267 is located in the groove so as to avoid contact with the limiting slide foot 251 and the like, thereby ensuring safety and avoiding friction loss. At the same time, a power connection piece 267 is provided in the first limiting slide groove 241. Circular cavities 268 with enlarged diameters are provided on the left and right sides of the plate 267. When the first electrical connector 26 is positioned there, the extrusion legs 263 on either side are no longer restricted by the inner wall of the first limiting chute 241 and will expand outward under the action of the spring 264. As a result, the two extrusion legs 263 simultaneously expand outward at the vertical through-hole 265 within the first electrical connector 26, causing the connecting rod 266 in the through-hole 265 to descend, with the lower end of the connecting rod 266 contacting the electrical connector plate 267, thereby achieving electrical connection. Conversely, when the first electrical connector 26 continues to move away from the electrical connector plate 267, the first limiting chute 241 of the circular cavity 268 narrows, squeezing the two extrusion legs 263 back. Both extrusion legs 263 push the connecting rod 266 upward through the inclined slot to break contact with the electrical connector plate 267, thereby achieving electrical disconnection.

[0038] See also Figures 9-11 Since there are two electrical connectors, one on the middle plate 25 and the other on the lower die 42, the lower end of the first electrical connector 26 of the middle plate 25 slides within the first limiting slot 241 and encounters the circular cavity 268 therein, switching the position. Meanwhile, the lower end of the second electrical connector 29 of the lower die 42 slides within the second limiting slot 252 and encounters the circular cavity 268 therein, switching the position. Consequently, the second electrical connector 29 of the lower die 42 is used in the same manner as the first electrical connector 26 of the middle plate 25. However, the lower end of the first electrical connector 26 of the middle plate 25 contacts the electrical connection tab 267, while the lower end of the second electrical connector 29 of the lower die 42 is inserted into the electrical connection port 269 at the upper end of the first electrical connector 26 of the middle plate 25 and contacts its bottom surface. The upper end of the second electrical connector 29 of the lower die 42 is electrically connected to the lower die 42 and the internal circuit, serving as the input power source.

[0039] It also includes a frame 3, the upper die base component 1 is installed on the frame 3, and a hydraulic component 31 is provided on the upper end of the frame 3. The hydraulic component 31 is used to control the lifting of the upper die base component 1, and the lower die base component 2 is installed at the bottom inside the frame 3.

[0040] The support structure of this device utilizes a monolithic frame 3 design. The upper die base component 1 is rigidly fixed to the upper portion of the frame 3. A hydraulic drive unit is located at the top of the frame 3. The output of this hydraulic unit is connected to the upper die base component 1, precisely controlling the vertical movement of the upper die base. The lower die base component 2 is mounted at the bottom of the frame 3's interior, forming a corresponding upper and lower structural layout with the upper die base component 1. This frame 3 design provides stable support and guidance for the upper die base, while ensuring sufficient working space for the lower die base translation mechanism 28. Furthermore, the hydraulic system enables controlled operation of the upper die base's pressing action.

[0041] Reference Figures 1-8 When the compression molding operation starts, the operator first places multiple layers of carbon fiber prepreg in the cavity of the lower concave mold 42 of the second lower mold base 22 according to the layering order, and starts the two motor drives of the translation structure. Each motor main shaft synchronously drives the two sets of sprockets 282 to rotate, and the transmission chain 281 engaged with the sprocket 282 pulls the first lower mold base 21 and the second lower mold base 22 to translate synchronously in the horizontal direction. The two lower mold base components 2 are mechanically interconnected by a rigid connecting plate 285, and their respective bases 23 are fixed to the chain 281 through a high-strength linking piece 284 to ensure movement synchronization.

[0042] When the chain 281 transfers the second lower die base 22 carrying the material to be processed to the processing station directly below the upper die base, the first lower die base 21 moves out synchronously, and the motor stops (set to automatic stop or triggered by the displacement sensor). At this time, the hydraulic component 31 drives the upper die base to press down vertically, so that the upper punch 41 and the lower die 42 of the second lower die base 22 are precisely clamped together. After the mold is clamped, the electric heating element embedded in the mold is activated to solidify and shape the laminated material according to the preset temperature curve.

[0043] After completing the hot pressing curing and turning off the heating element, the hydraulic component 31 lifts the upper mold base to open the mold, and the motor reverses to drive the chain 281 to move the second lower mold base 22 of the molded product out of the processing area. At the same time, the first lower mold base 21 is reset to the processing station to prepare for subsequent production. At this time, the staff performs a quick change operation on the moved second lower mold base 22.

[0044] The staff performs a quick-change operation on the removed first lower die base 21 or the second lower die base 22: the middle plate 25 is pushed in the direction perpendicular to the movement of the chain 281, and the extrusion foot 263 at its bottom is squeezed inward by the side wall of the limiting slide of the bottom plate 24, and the linkage connecting rod 266 is lifted up and separated from the connecting piece 267, cutting off the power supply to the lower die 42; the middle plate 25 is continuously pushed until its limiting slide foot 251 is completely separated from the slide, and at the same time, the lower die 42 module pre-loaded with new material is pushed in from the opposite side to realize the forced replacement of the old module; the removed middle plate 25 and the lower die 42 are transferred to a special workbench, and the following operations are performed in sequence: taking out the molded product, cleaning the cavity with high-pressure air, spraying the high-temperature resistant release agent, and laying the prepreg layer by layer according to the layer design.

[0045] By the time the first lower die holder 21 has finished machining the current workpiece, the second lower die holder 22 has already pre-laid the material and is ready for use. This dual-station, alternating cycle allows for parallel processing of material preparation and hot pressing, eliminating the idle time associated with cleaning and laying materials in traditional processes.

[0046] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
