[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The core of the utility model is to provide a preformer for fiber cloth, which is easy to process and has a compact structure.

[0037] For a specific embodiment of the preformer for fiber cloth provided by the present invention, please refer to Figures 1 to 8 , including a plurality of molding modules 5 fixedly connected as one body, such as in this embodiment, three molding modules 5 are provided, and in other embodiments, five or other numbers may be provided. The preformer may be made of nylon material to keep the structure light and easy to prepare and process. Specifically, the molding module 5 may be formed by 3D printing.

[0038] The forming module 5 is provided with a forming channel 51, and the forming channels 51 on each forming module 5 are connected in sequence to form a running channel 4, and the fiber cloth passes through the running channel 4 to complete the forming process. The size of the gap in the running channel 4 can be determined according to the thickness of the fiber cloth. In addition, the surface of the running channel 4 is preferably kept relatively smooth to reduce the influence of uneven friction on the running of the fiber cloth.

[0039] An observation port 61 communicating with the shaping passage 4 is disposed on the outer surface of at least one molding module 5 . For example, in this embodiment, observation ports 61 are disposed at both ends of the outer surface of each molding module 5 in the first direction X.

[0040] The preformer in this embodiment is formed by connecting a plurality of forming modules 5 with forming channels 51. The forming channels 51 are arranged in sequence along the running direction of the fiber cloth to form a running channel 4. The fiber cloth can enter from the entrance of the running channel 4, gradually deform under the guidance of the running channel 4, and move out from the outlet of the running channel 4 to achieve the forming, which is easy to operate. Among them, the preformer can be directly fixedly connected through different forming modules 5, without the need to form the running channel 4 after the preformed plate and the core mold structure are arranged and assembled at intervals, which can reduce the difficulty of assembly and reduce the setting of the support platform originally used to support the preformed plate, which is conducive to the miniaturization and compactness of the structure.

[0041] For the setting of observation port 6, Figure 1 As shown, at least one end of at least one molding module 5 in the first direction X is provided with a groove 6, the space in the groove 6 at least partially overlaps with the running channel 4, and the observation port 61 is provided on the groove surface of the groove 6, so that the edge of the fiber cloth can pass through the groove 6 during the process of the fiber cloth moving in the running channel 4. In addition, on the molding module 5, along the extension direction of the molding channel 51 (i.e., the running direction or moving direction of the fiber cloth therein), protrusions 62 are respectively formed at both ends of the groove 6, and the molding channel 51 is partially located in the protrusions 62. After the partial structure of the fiber cloth moves out of one protrusion 62 and enters the groove 6, it enters another protrusion 62. The fiber cloth at the groove 6 is equivalent to being exposed from the molding module 5. In addition to being observable, the position angle of the fiber cloth can also be adjusted. For example, if the fiber cloth is crooked, the fiber cloth can be pushed and pulled from the groove 6 for adjustment.

[0042] Of course, in other embodiments, the end surface of the molding module 5 in the first direction X may also be a plane, and the observation port 6 is arranged on the plane, so that the fiber cloth can be observed but cannot be adjusted.

[0043] In order to reduce the space occupied by the fiber cloth during the molding process, Figure 1 As shown, the entrance and exit of the shaping channel 4 are oriented in different directions, specifically, they can be oriented perpendicularly, and in other embodiments, they can also be oriented at other angles. For example, the entrance is oriented upward or downward, and the fiber cloth enters along the direction of the entrance, that is, along the up and down direction, and the exit is oriented in the horizontal direction, and the fiber cloth moves out along the direction of the exit, that is, along the horizontal direction. The fiber cloth will turn during the movement in the shaping channel, and the part of the fiber cloth placed outside the preformer will not occupy the plane space in one direction. For example, the fiber cloth can be placed vertically at the entrance of the shaping channel, reducing the space occupied in the horizontal direction, and other positions in the horizontal direction can be placed on other equipment to avoid interference between the fiber cloth and other equipment, reduce interference with other surrounding equipment, and transform the existing fiber cloth preforming process using a longer preformed plate into a state where a large deformation can be achieved.

[0044] To improve the applicability of the preformer, such as Figure 1 As shown, the inlet of the shaping channel 4 is a straight opening to adapt to the shaping operation of most planar fiber cloths, and the outlet is a folded-line opening to adapt to the target shape of the fiber cloth.

[0045] For easy disassembly and assembly, different forming modules 5 are fixed with bolts. In other embodiments, welding connection can also be adopted. Specifically, different forming modules 5 can be provided with bolt holes at the protrusions 62 to realize bolt connection.

[0046] To achieve compactness, such as Figure 1As shown, each forming module 5 is connected as a whole to form an L-shaped structure. At this time, the bottom of the preformer also has sufficient area and sufficient support capacity. The entrance of the running channel 4 is located on the top surface of the L-shaped structure, and the exit is located on the side of the L-shaped structure.

[0047] For the arrangement of each molding module 5, Figure 1 As shown, the three forming modules 5 are respectively an inlet module 1, an intermediate module 2 and an outlet module 3, the inlet module 1 is fixed to the top surface of the intermediate module 2, and the outlet module 3 is fixed to the side surface of the intermediate module 2. The inlet module 1, the intermediate module 2 and the outlet module 3 are arranged in an L shape to form an L-shaped structure.

[0048] For the walking channel 4, if Figure 2 As shown, the forming channel 51 on the inlet module 1 is the inlet channel 41 that runs from the top surface to the bottom surface of the inlet module 1, the forming channel 51 on the outlet module 3 is the outlet channel 43 that runs through the two sides of the outlet module 3, and the forming module 5 of the intermediate module 2 is the intermediate channel 42 that connects the inlet channel 41 and the outlet channel 43. The inlet channel 41 is the inlet section of the shaping channel 4, the intermediate channel 42 is the intermediate section of the shaping channel 4, and the outlet channel 43 is the outlet section of the shaping channel 4.

[0049] The inlet of the inlet channel 41 is the inlet of the shaping channel 4, and its shape is the same as the original shape of the fiber cloth before the shaping operation. Specifically, the fiber cloth is planar, and the inlet of the inlet channel 41 is a linear opening. The outlet of the outlet channel 43 is the outlet of the shaping channel 4, and its shape is the same as the target shape of the fiber cloth to be shaped. It is set according to the cross-sectional shape that the fiber cloth needs to achieve according to the design requirements. For example, the outlet of the outlet channel 43 is a folded line opening, specifically a Z-shaped opening with a right angle at the fold. After the fiber cloth is shaped, a bent fiber cloth with the same outlet shape as the outlet of the outlet channel 43 is formed. The part of the shaping channel 4 between the inlet and the outlet is connected inside the preformer, and gradually transitions from the straight line shape of the inlet to the cross-sectional shape of the outlet required by the design.

[0050] For entry module 1, such as Figure 3 and Figure 4 As shown, the entrance module 1 includes a first main block 11 and a first side block 12 arranged in sequence along a first direction X, and the first side block 12 protrudes from the first main block 11 along a second direction Y, so that the first side block 12 can have more space to flexibly set the shape of the entrance channel 41.

[0051] The entrance channel 41 includes a first main channel 411 provided on the first main block 11 and a first side channel 412 provided on the first side block 12, and the first main channel 411 is connected with the first side channel 412 along the first direction X. The openings of the first main channel 411 on the top and bottom surfaces of the first main block 11 are parallel linear openings. The opening of the first side channel 412 on the top surface of the first side block 12 is a linear opening that is colinear with the opening of the first main channel 411 on the top surface of the first main block 11, and the opening of the first side channel 412 on the bottom surface of the first side block 12 forms an angle with respect to the opening on the bottom surface of the first main block 11.

[0052] At this time, the first main channel 411 is a planar channel, and the first side channel 412 is a torsion surface that smoothly transitions from the top surface to the bottom surface of the first side block 12. The portion of the fiber cloth in the first main channel 411 remains unchanged, while the portion in the first side channel 412 gradually deforms during the movement of the fiber cloth.

[0053] For the intermediate module 2, if Figure 5 and Figure 6 As shown, the intermediate module 2 includes a second top plate 21, a second side plate 23 and a second middle block 22. The second top plate 21 fixes the top end of the second side plate 23 at one end in the second direction Y to form an L-shaped plate. The second middle block 22 is fixed to the bottom surface of the second top plate 21 and is fitted and fixed to the side surface of the second side plate 23. The two ends of the second top plate 21 in the first direction X and the two ends of the second side plate 23 in the first direction X extend out of the second middle block 22 respectively, and the extended parts can facilitate the fixed connection of the intermediate module 2 with other molding modules 5. Specifically, the two ends of the second top plate 21 extending out of the second middle block 22 in the first direction X are fixedly connected to the inlet module 1, and the second side plate 23 extends out of the two ends of the second middle block 22 in the first direction X and is fixedly connected to the outlet module 3.

[0054] The parts of the second middle block 22 at both ends of the first direction are located between the second top plate 21 and the protruding parts of the second side plate 23 and can be used as grooves 6. An observation port 61 is provided to facilitate observation of the direction of the fiber cloth in the middle module 2.

[0055] For export module 3, if Figure 7 and Figure 8 As shown, the outlet module 3 includes a third main block 31 and a third side block 32 arranged in sequence along the first direction X. The top surface of the third side block 32 protrudes from the top surface of the third main block 31, and the third side block 32 can have more space to flexibly set the shape of the outlet channel 43.

[0056] The outlet channel 43 includes a third main channel 431 provided on the third main block 31 and a third side channel 432 provided on the third side block 32, and the third main channel 431 is connected with the third side channel 432 along the first direction X. The openings of the third main channel 431 on two opposite sides of the third main block 31 are parallel linear openings. The openings of the third side channel 432 on two opposite sides of the third side block 32 are both folded line openings.

[0057] The working principle of the preformer in this embodiment includes: feeding the straight fiber cloth from the entrance of the shaping channel 4 on the preformer, continuously moving to the exit in the shaping channel 4 and gradually deforming, and the position of the fiber cloth can be observed or adjusted by means of the observation port 61, and finally forming a fiber cloth with a desired cross section at the exit of the shaping channel 4. In addition, the preformer can be set at the entrance of the hot mold in the composite material pultrusion production process to realize the preforming of the fiber cloth before the fiber cloth enters the hot mold for curing.

[0058] The advantages of the preformer in this embodiment include: the shape change and the shape of the seam of the shaping channel 4 can be customized according to the cross-sectional shape of the fiber cloth, which is suitable for the preforming of fiber cloth with complex special-shaped cross-sections, and can realize the forming process of fiber products with relatively complex cross-sectional shapes in pultruded fiber products; the inlet module 1, the middle module 2 and the outlet module 3 are fixed and installed as a whole by bolts, and the connection is convenient; the inlet module 1, the middle module 2 and the outlet module 3 are arranged at intervals through the protrusions 62 to form an observation port 61, which is convenient for observing and adjusting the shape of the fiber cloth, and convenient for checking the shape deviation state of the fiber cloth at all times, and the displacement can be corrected in time according to requirements. At the same time, the protrusion 62 can also be used as a bolt connection position; the shaping channel 4 is continuous and uninterrupted, and can maintain good smoothness, and the integrated configuration is conducive to avoiding multiple local high stress phenomena, improving the utilization efficiency of material bearing, and at the same time, it can reduce the occupied space, so as to achieve the effect of improving the utilization rate of production space and make the structure compact.
