Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and in particular to a tooling for cutting and laying preformed fibers using the HP-RTM process. Background Technology

[0002] In the HP-RTM process, when the product structure is complex, the fibers need to be pre-formed to transform the fiber cloth from a planar state into a 3D product structure. Since most products have different thicknesses in different areas to meet varying strength requirements depending on the application, for complex shapes, the fiber cloth can be pre-pressed using a mold. Then, a mounting fixture is used to locate and apply reinforcing fibers to the areas requiring reinforcement. The mounting fixture also trims the boundaries of the preform to ensure it fits the mold cavity boundaries.

[0003] Existing technologies often use aluminum or wood substitutes for tooling, which are prone to wear at the cutting edges during long-term use, resulting in significant deviations between the cut preform boundaries and the design boundaries. Furthermore, using LED strips for positioning reinforcing fiber sheets often results in poor light penetration through the fibers, leading to inaccurate positioning or difficulty in identifying the positioning area. Utility Model Content

[0006] In a preferred embodiment, the present invention may be further configured such that the outer side of the reinforcing area contour block is provided with a handle for gripping, and the surface that fits with the tooling body is provided with a recessed cavity, which engages with the corresponding area through the recessed cavity.

[0007] In a preferred embodiment, the present invention may be further configured such that cutting boundary blocks are fixed at the four perimeter walls of the bottom of the tooling body, and the cutting boundary blocks are used as cutting references.

[0008] In a preferred embodiment, the tooling body may be further configured such that it is made of lightweight, rust-resistant material, including aluminum or wood.

[0009] In a preferred embodiment, the present invention may be further configured such that the cutting boundary block is made of stainless steel, including galvanized stainless steel.

[0010] In a preferred embodiment, the present invention may be further configured such that a quick-release pad is provided between the cutting boundary block and the tooling body.

[0011] In a preferred embodiment, the present invention may be further configured such that a frame equipped with rollers is fixed to the bottom of the tooling body.

[0012] Beneficial effects: This utility model provides a fiber preform cutting and laying fixture for HP-RTM process. The fixture's main body is made of rust-resistant material, reducing its overall weight. Stainless steel or galvanized steel plates are used as cutting boundary blocks, significantly improving wear resistance. The reinforcement area features contour-following positioning blocks, which are quickly snapped into place with the fixture body. The boundary of the reinforcement area is defined along the positioning block boundary, and then the reinforcement fiber is adhered using adhesive spraying. This design allows for visual observation of the laying boundary in any environment. Even if the reinforcement fiber misalignment occurs during preform transfer, it can be quickly detected and adjusted visually. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-3As shown, an HP-RTM process fiber preforming cutting and laying fixture includes a fixture body 1 for placing fiber cloth products. The fixture body 1 is provided with several sets of reinforcing area imitation blocks 2 that define the laying area. The reinforcing area imitation blocks 2 are engaged with the corresponding areas. When the fiber cloth product is processed into a 3D three-dimensional state, it is placed in the fixture body 1. The corresponding reinforcing area imitation blocks 2 are engaged with the areas to be reinforced. Then, lines are drawn along the boundaries of the imitation blocks to define the area. Finally, laying and reinforcement operations are performed within the drawn area.

[0021] The outer side of the reinforcing area contour block 2 is provided with a handle for gripping, and a recessed cavity 6 is provided on the surface that is in contact with the tooling body 1. The recessed cavity 6 is engaged with the corresponding area to facilitate the gripping operation of the reinforcing area contour block 2.

[0022] The tooling body 1 has a cutting boundary block 4 fixed at the bottom of the four sides. The cutting boundary block 4 serves as the cutting reference to prevent excessive cutting or uneven cutting.

[0023] The main body of the tooling 1 is made of lightweight, rust-resistant materials, including aluminum or wood, while the cutting boundary block 4 is made of stainless steel, including galvanized stainless steel. Using aluminum or wood as the main body of the tooling provides rust prevention and reduces the overall weight of the tooling. In the cutting and laying process, electric shears are often used to trim the preformed parts along the tooling boundary. Long-term use can easily lead to wear on the tooling boundary. Using stainless steel or galvanized steel plates as the cutting boundary block can greatly improve its wear resistance.

[0024] A quick-release pad 5 is provided between the cutting boundary block 4 and the tooling body 1. By adding or removing the corresponding number of pads, different cutting widths can be accommodated.

[0025] The bottom of the tooling body 1 is fixed with a frame 3 equipped with rollers to facilitate the movement of the tooling.

[0026] It should be noted that in this article, relational terms such as first and second are used only to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities.

[0027] The above examples are merely illustrative of this utility model and do not constitute a limitation on the scope of protection of this utility model. All designs that are the same as or similar to this utility model are within the scope of protection of this utility model.
