Description
Technical Field
[0001] This utility model relates to the field of closed-angle beam forming technology, and in particular to a tooling for forming a positive mold of a closed-angle C-shaped beam. Background Technology
[0002] Some aircraft structural components have closed-angle structures. For example, some beam structures have an angle of less than 90° between the web and flange of the inner surface, thus forming a closed angle. Currently, composite materials are widely used in the aerospace field due to their superior properties, and an increasing number of high-precision composite material parts are using curing molding processes.
[0003] Composite material C-beams are a commonly used structural form for composite parts. The conventional manufacturing process involves using either a male or female mold. After pre-forming with the male mold, the C-beam is transferred to the female mold for final molding. After curing, the composite part requires demolding, which is accomplished by separating the C-beam from the female mold, offering good operability. However, this process requires two sets of tooling, one for the male mold and one for the female mold, resulting in higher costs. Furthermore, the tooling involves separation during the transfer from the male mold to the female mold and demolding processes, and repeated use of the tooling may affect the surface accuracy of the C-beam.
[0004] Therefore, there is an urgent need for a closed-angle C-beam positive mold forming fixture to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a positive mold forming fixture for closed-angle C-shaped beams. The same positive mold forming fixture is used for both preforming and forming processes, which improves demolding efficiency. Under the condition of reducing the cost of tooling, the disassembly of the tooling is reduced or even eliminated, preventing the tooling accuracy from being affected by repeated disassembly.
[0006] To address the aforementioned problems in the existing technology, this utility model adopts the following technical solution:
[0007] The fixture for forming the positive mold of the closed-angle C-beam includes:
[0008] Base;

[0021] The closed-angle C-shaped beam male die forming tool has the advantages that:
[0022] This utility model provides a closed-angle C-beam male mold forming fixture. The forming assembly includes a fixture body and two auxiliary forming parts. The fixture body is set on a base, and the two auxiliary forming parts are respectively set on both sides of the fixture body. There are two embedded parts, which are spaced apart and embedded in the fixture body along the length of the fixture body. A load-bearing member connects the two embedded parts. Before forming the C-beam part, the embedded parts are pre-embedded in the allowance area at the large and small ends of the part located on the base. During the pre-embedding process, the load-bearing member serves as an auxiliary reference to ensure that the distance between the two embedded parts meets the load-bearing requirements of the load-bearing member. The embedded parts and the part are then solidified. Before demolding, the load-bearing member is placed between the two embedded parts at the large and small ends of the part, ensuring that both ends of the load-bearing member are in contact with the corresponding embedded parts. Then, a pushing force is applied to push the closed-angle C-beam out of the forming fixture for demolding. The load-bearing member shares the pressure applied to the part during demolding, preventing the part from being damaged by pressure. The preforming and forming processes of the closed-angle C-beam utilize the same male mold forming fixture, simplifying the demolding operation and improving demolding efficiency. Furthermore, the fixture components used are relatively lightweight, reducing the probability of safety accidents due to operational errors and enhancing demolding safety. By reducing fixture costs, disassembly of the fixture is minimized or eliminated, reducing demolding difficulty and time, preventing repeated disassembly from affecting fixture accuracy, and increasing the number of times the fixture can be used.

[0042] AsFigures 1-6 As shown, in the present embodiment, the closed angle C-beam male die forming tool includes a base 1, a forming assembly 2, embedded parts 3 and a force bearing rod part 4. Among them, the forming assembly 2 includes a tool main body 21 and two auxiliary forming parts 22, the tool main body 21 is arranged on the base 1, and the two auxiliary forming parts 22 are arranged on the two sides of the tool main body 21 respectively, the number of embedded parts 3 is two, along the length direction of the tool main body 21, the two embedded parts 3 are arranged at intervals and embedded in the tool main body 21, and the force bearing rod part 4 is connected between the two embedded parts 3. Specifically, the base 1 is arranged as a curing platform, and the forming assembly 2 is fixedly installed on the end face of the base 1, wherein the tool main body 21 is fixedly connected with the base 1, and the two auxiliary forming parts 22 are respectively connected with the two side walls of the tool main body 21. Optionally, the tool main body 21 and the auxiliary forming part 22 are an integral structure during use. The force bearing rod part 4 is arranged on the base 1 and plays a role of sharing pressure during demolding, and the two ends of the force bearing rod part 4 are provided with embedded parts 3, which are embedded in the excess area of the C-beam of the base 1 during forming. The working process of the closed angle C-beam male die forming tool is as follows: first, before the C-beam part is formed, the embedded parts 3 are embedded in the excess area of the size end of the part located on the base 1, and during the embedding process, the force bearing rod part 4 serves as an auxiliary reference to ensure that the distance between the two embedded parts 3 meets the force bearing requirement of the force bearing rod part 4, and the embedded parts 3 are cured and formed with the part. Before demolding, the force bearing rod part 4 is placed between the two embedded parts 3 of the size end of the part, so that the two ends of the force bearing rod part 4 are in contact with the corresponding embedded parts 3, the middle part of the force bearing rod part 4 can be fixed by using a tool to avoid bending of the force bearing rod part 4 during force bearing. Then, a jack is used to apply a pushing force to the part to push the closed angle C-beam out of the forming tool for demolding, and the force bearing rod part 4 shares the pressure applied to the part during demolding to prevent damage to the part due to excessive pressure. The pre-forming and forming processes of the closed angle C-beam use the same male die forming tool, which simplifies the demolding operation of the closed angle C-beam, improves the demolding efficiency, and the weight of the used tooling parts is relatively small, which reduces the probability of safety accidents caused by operation errors and improves the safety of demolding. Under the condition of reducing the cost investment of the tool, the demolding difficulty and time are reduced, the influence of repeated disassembly on the precision of the tool is prevented, and the use frequency of the tool is improved.
[0043] Further, with reference to Figure 1 and Figure 3The force bearing rod 4 comprises a fixed part 41 and a connecting rod part 42. The fixed part 41 is connected to the embedded part 3. The number of the fixed part 41 is two. The two ends of the connecting rod part 42 are respectively connected to the two fixed parts 41. Specifically, the number of the connecting rod part 42 is two. Along the length direction of the tool main body 21, the two connecting rod parts 42 are parallel and spaced. In the demolding process, the force bearing rod 4 plays a role of sharing pressure. In the embedding process, the force bearing rod 4 serves as an auxiliary reference to ensure that the distance between the two embedded parts 3 meets the force bearing requirement of the force bearing rod 4.
[0044] Further, referring to Figure 1 and Figure 3 , the closed angle C-shaped beam positive mold forming tool further comprises a first connecting piece 5. The fixed part 41 is provided with a through hole. The end of the connecting rod part 42 is provided with a mounting hole. The first connecting piece 5 passes through the through hole and is connected to the mounting hole. The first connecting piece 5 is provided as a bolt. The connecting rod part 42 is connected to the fixed part 41 through the bolt, which is convenient for disassembly and installation.
[0045] Further, referring to Figure 1 and Figure 6 , the closed angle C-shaped beam positive mold forming tool further comprises a force bearing block 6. The force bearing block 6 is fixedly arranged on the tool main body 21. The force bearing block 6 is spaced apart from the embedded part 3 along the length direction of the tool main body 21. Specifically, the force bearing block 6 is fixed on the tool during the part demolding process and does not contact the part. After the part is completed, the force bearing block 6 is fixed on the forming assembly 2 to ensure tight fixation. During the demolding process, the force bearing block 6 serves as a support point of the jack. The jack is used to apply a pushing force between the force bearing block 6 and the embedded part 3 to push the closed angle C-shaped beam out of the forming tool for demolding.
[0046] Optionally, the auxiliary forming part 22 has an inverted trapezoidal structure. The auxiliary forming part 22 is assembled with the tool main body 21 to meet the shape requirement of the C-shaped beam.
[0047] Further, referring to Figure 1 , the closed angle C-shaped beam positive mold forming tool further comprises a backing plate 7. The backing plate 7 is installed on the tool main body 21 and supports the force bearing rod 4 below. The middle part of the force bearing rod 4 can be fixed by using the backing plate 7 to avoid bending of the force bearing rod 4 during the force bearing process.
[0048] Further, referring to Figure 1The C-type beam positive mold forming tool further comprises a second connecting piece 8, the auxiliary forming piece 22 is provided with a connecting hole, the tool main body 21 is provided with a positioning hole, and the second connecting piece 8 passes through the connecting hole and is connected to the positioning hole. Specifically, the second connecting piece 8 is arranged as a bolt, the tool main body 21 is integrally formed by pressure casting or the like, and the auxiliary forming piece 22 is integrally formed by pressure casting or the like, so that the structural strength is high. The auxiliary forming piece 22 is connected to the tool main body 21 through the second connecting piece 8, and in the demolding process, the forming assembly 2 is generally not disassembled, but when the force rod 4 is obviously bent and the part is difficult to demold, the second connecting piece 8 between the tool main body 21 and the auxiliary forming piece 22 is disassembled, and the tool main body 21 and the auxiliary forming piece 22 are separated. Since the structure of the auxiliary forming piece 22 is small, and the part is demolded in the direction of the length of the tool main body 21 as an axis, the part can be easily demolded.
