Description

Technical Field

[0001] This utility model belongs to the field of thermoplastic composite material molding technology, and relates to a tooling for molding thermoplastic composite material pultrusion winding profiles. Background Technology

[0002] The main drawbacks of existing thermoplastic composite pultrusion molding processes include uneven material flow, long molding cycles, high internal stress in the product, and unstable surface quality. These drawbacks are closely related to the physical properties of the thermoplastic composite, molding process parameters, and mold design. For example, the high viscosity of thermoplastic composites leads to uneven flow during pultrusion; the long molding cycle is related to the heating and cooling time; high internal stress may be due to uneven temperature and pressure distribution during molding; and unstable surface quality may be related to mold surface treatment and mismatches in the thermal expansion coefficients of the materials. Conventional solutions include optimizing molding process parameters, improving mold design, using preheating or post-treatment techniques, and adopting new composite materials; however, these methods also have drawbacks. While optimizing process parameters can improve molding results, it requires extensive experimentation to determine the optimal parameters, which is time-consuming and labor-intensive. Therefore, there is an urgent need for a new tooling for molding thermoplastic composite pultrusion spiral wound profiles to address these problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tooling for forming thermoplastic composite pultrusion winding profiles, so as to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a tooling for forming thermoplastic composite pultrusion winding profiles, including: a feeding roller and a lower support frame, a set of tension adjusting rollers for adjusting the tension of the composite material is provided on the left side of the feeding roller, a set of connecting frames for limiting the height position of the tension adjusting roller is provided on the outer side of the tension adjusting roller, a set of motors for driving the tension adjusting roller to move up and down is provided on the rear side of the tension adjusting roller, and a set of pressing components for thermoplastic extrusion of the composite material is provided on the left side of the tension adjusting roller;

[0005] The pressing component includes an electric cylinder and an extrusion groove. The lower end of the electric cylinder is provided with a set of carrier plates for supporting it. The cross-section of the carrier plate in plan view is a rectangular structure. The lower end of the inner side of the four external corners of the carrier plate is provided with a set of support columns for supporting it. The lower end of the electric cylinder is provided with a set of telescopic heads for driving the inner pressing plate to move up and down. The telescopic heads are integrated with the electric cylinder and serve as the driving telescopic end of the electric cylinder. The telescopic heads pass through the center of the two sets of carrier plates at different heights.

[0006] In a preferred embodiment, the lower end of the telescopic head is provided with a set of inner pressure plates for controlling the up-and-down movement of the extrusion grooves. The lower end of the inner pressure plates is provided with two sets of extrusion grooves for limiting and guiding the composite material after it has been hot-melted. The pressing component is provided with two sets. When the operator needs to mechanically thermoplasticize the composite material, the composite material raw material is released through the feeding roller, and tension adjustment roller is used to tension and support it. The composite material is thermoplasticized and softened inside the pressing component, while the stretching effect is improved. Then, the electric cylinder controls the telescopic head to move up and down, and the inner pressure plate and extrusion grooves limit the degree of extrusion of the composite material. Then, the pultrusion component is used to perform horizontal pultrusion of the thermoplastic composite material, which makes it easier to adjust the pultrusion requirements of different composite materials according to different needs.

[0007] In a preferred embodiment, a pultrusion component for pultruding the hot-melted composite material is provided between the two sets of pressing components.

[0008] In a preferred embodiment, the pultrusion component includes a top plate and a lower support cylinder. The lower end of the top plate is provided with a plurality of lifting columns for controlling the up and down movement of the top plate, and the lower end of the plurality of lifting columns is provided with a set of pads for mounting and fixing their lower ends.

[0009] In a preferred embodiment, the outer side of the pad is provided with a set of movable frames for supporting it. At the lower middle position of the lower end of the movable frame, a set of lower support cylinders is provided for adjusting the overall height of the movable frame. When the operator uses the pultrusion component to change the toughness of the composite material, the overall height of the movable frame is adjusted by using the lower support cylinders. Then, after controlling the up and down movement of the top plate by several sets of lifting columns, the top plate and the external forming pressure plate perform pultrusion operation on the composite material. The external forming pressure plate is selected according to the actual pultrusion molding shape.

[0010] In a preferred embodiment, the lower support cylinder is a control electric cylinder, and the several sets of lifting columns are all electric telescopic rods, with two sets of external connection holes on the upper end of their top plates for connecting and fixing with the external forming pressure plates.

[0011] In a preferred embodiment, the left side of the pressing component is provided with a set of rear guide rollers for conveying the molded composite material. The rear guide rollers are all self-rotating structures. The left side of the rear guide rollers is provided with a set of winding rollers for winding the molded composite material.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the composite material raw material is released by the feeding roller, and is tensioned and supported by the tension adjusting roller. The composite material is thermoplasticized and softened inside the pressing component, while the stretching effect is improved. Then, the electric cylinder controls the telescopic head to move up and down, and the inner pressure plate and extrusion groove limit the degree of extrusion of the composite material. Then, the pultrusion component performs horizontal pultrusion operation on the thermoplastic composite material, which makes it easier to adjust the pultrusion requirements of different composite materials according to different needs.

[0013] When the toughness of a composite material is altered by using pultrusion components, the overall height of the movable frame is adjusted by using a lower support cylinder. Subsequently, the top plate is moved up and down by several sets of lifting columns. The top plate and the external forming plate then perform pultrusion on the composite material. The external forming plate is selected according to the actual pultrusion shape. Attached Figure Description
