Description

Technical Field

[0001] The utility model relates to the technical field of BIPV, in particular to a multi-traction rod bending adjustment system for pultrusion molding of composite material frames. Background Art

[0002] Currently, pultrusion technology primarily focuses on the production of straight composite frames. However, with the growing development of building-integrated photovoltaics (BIPV) technology, the demand for curved composite frames has also rapidly increased. However, existing technologies are limited by the fixed pultrusion die structure design, making it difficult to produce composite frames with diverse curved shapes. Therefore, the pain point of existing technologies is that whenever the curved shape of the composite frame needs to be adjusted, the die must be replaced, which not only increases production costs but also reduces production efficiency and flexibility. Utility Model Content

[0003] The purpose of this utility model is to design a multi-traction rod bending adjustment system for pultrusion molding of composite material frames to address the problem that existing composite material frame molding molds are unable to produce curved composite material frames. The system can achieve high-precision and high-flexibility bending molding of composite material frames, thereby solving the above-mentioned problem.

[0004] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0005] The utility model designs a multi-traction rod bending adjustment system for pultrusion of composite material frames, which includes:

[0006] a bottom plate having a first direction and a second direction perpendicular to each other;

[0012] After being pulled out of the frame semi-curing device, the composite material frame is bent and adjusted around each frame drawing rod to form a composite material frame structure with an arc.

[0013] Specifically, the multi-traction rod bending adjustment system designed in the present invention for pultrusion molding of composite material frames can flexibly adjust the traction path by introducing multiple non-linearly arranged traction rods combined with the traction system, thereby achieving high-precision and high-flexibility bending molding of composite material frames. This not only overcomes the problem of high cost of modifying the curvature in the existing technology, but also meets the urgent demand for diversified frames in application fields such as BIPV.

[0014] Furthermore, a multi-traction rod bending adjustment system for pultrusion molding of composite material frames: the frame molding mold, frame semi-curing device, frame traction device and frame cutting device are arranged along a first direction and are located on the same line.

[0015] Furthermore, a multi-traction rod bending adjustment system for composite frame pultrusion molding is provided: the frame semi-curing device is composed of multiple independent heating modules, each heating module can independently control the temperature to achieve different curing treatments for materials in different parts.

[0016] Furthermore, a multi-traction rod bending adjustment system for composite frame pultrusion molding is provided: the frame traction device is made of high-temperature resistant material to adapt to the composite material after high-temperature curing.

[0017] Furthermore, a multi-traction rod bending adjustment system for pultrusion of composite material frames: the frame cutting device is a laser cutting device or a water jet cutting device, which is used to accurately cut the composite material frame after bending.

The system structure introduces multiple non-linearly arranged frame traction rods and combines them with a frame traction device to flexibly adjust the traction path of the composite material frame to achieve high-precision and high-flexibility bending molding of the composite material frame. This not only overcomes the problem in the existing technology that changing the bending curvature of the composite material frame requires replacing the mold, resulting in high cost, low production efficiency and flexibility, but also meets the urgent demand for composite material frames with diversified curved shapes in application fields such as BIPV.

[0032] Example 1

[0033] like Figure 1 As shown, in this embodiment 1, a multi-traction rod bending adjustment system for pultrusion of composite material frame is designed, and the system includes:

[0034] A bottom plate 1 having a first direction and a second direction perpendicular to each other;

[0035] A frame forming mold 2, which is fixedly arranged on the bottom plate 1;

[0036] The frame semi-curing device 3 is fixedly arranged on the bottom plate 1 and is located downstream of the frame forming mold 2. The frame semi-curing device 3 is composed of multiple independent heating modules, each of which can independently control the temperature, so that different curing treatments can be performed on the materials in different parts;

[0037] A frame pulling device 4 is fixedly mounted on the bottom plate 1 and is located downstream of the frame semi-curing device 3. The frame pulling device 4 is made of a high-temperature resistant material to adapt to the composite material after high-temperature curing.

[0038] A frame cutting device 5 is fixedly mounted on the bottom plate 1 and located downstream of the frame pulling device 4. The frame cutting device 5 is a laser cutting device or a water jet cutting device, and is used to accurately cut the composite material frame 7 after bending and forming. The frame forming mold 2, the frame semi-curing device 3, the frame pulling device 4, and the frame cutting device are arranged along a first direction and are located on the same line.

[0039] and a plurality of frame traction rods 6, which are arranged on the bottom plate 1 between the frame semi-curing device 3 and the frame traction device 4, and the plurality of frame traction rods 6 have a degree of freedom of movement in a first direction and a second direction;

[0040] After being pulled out of the frame semi-curing device 3 , the composite material frame 7 is wound around the frame drawing rods 6 for bending adjustment to form a composite material frame structure with an arc.

[0041] Preferably, the frame traction rod 6 in the above embodiment 1 is rotatably arranged on the bottom plate 1, so as to form rolling contact with the composite material frame 7 to reduce the traction force.

[0042] Specifically, a number of frame traction rods 6 are arranged between the frame forming mold 2 and the pultrusion traction equipment (frame traction device 4). During the pultrusion process, the fiber and resin mixed material is initially cured through the frame forming mold 2 and the semi-curing device 2, and then enters the frame traction rod 6 system path. The frame traction rod 6 adjusts its position on the base plate 1 so that the cured material is subjected to forces in different directions when passing through the traction rod 6 system, thereby achieving bending forming.

[0043] By adjusting the traction rod 6 in the system designed in Example 1 to different positions, the composite material frame 7 can be formed into a desired curved shape, such as Figure 2 and Figure 4 As shown, Figure 2 The schematic diagram of the structure of the composite material frame 7 is similar to the "S" shape, and several Figure 2 The S-shaped frame structure shown in the figure can be assembled to form Figure 3The installation structure diagram shown in the figure can meet the needs of BIPV and other application fields for composite material frames with diverse curved shapes; Figure 4 The schematic diagram of the structure of the composite material frame 7 is similar to the "arc" type, and several Figure 4 The "arc" frame structure shown in the figure can be assembled to form a Figure 5 The installation structure diagram shown in the figure can meet the needs of BIPV and other application fields for composite material frames with diverse curved shapes.

[0044] like Figure 6 As shown, by adjusting the position of the traction rod 6, the multi-traction rod bending adjustment system designed by the present invention for pultrusion molding of composite material frames can also be used to form straight composite material frames.

[0045] The above preferred embodiments of the present invention are only used to explain the present invention and are not intended to limit the present invention. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
