Description

Technical Field

[0001] The invention relates to the technical field of molding tooling, and in particular to an adjustable curved carbon fiber molding tooling. Background Art

[0002] Carbon fiber is a new type of fiber material with high strength and high modulus fiber with a carbon content of more than 95%. Carbon fiber is composed of graphite sheets composed of condensed polycyclic aromatic hydrocarbons and belongs to a two-dimensional chaotic layer graphite structure. Carbon fiber is lighter than metal aluminum, but its strength is higher than steel, and it has the characteristics of high hardness, high strength, light weight, high chemical resistance, and high temperature resistance. Carbon fiber has the inherent intrinsic properties of carbon materials and the softness and processability of textile fibers. It is a new generation of reinforcing fiber, which also makes it very popular in aerospace, civil engineering, military, racing and other competitive sports products. Carbon fiber is cast using carbon fiber molds during production. The molding tooling in the existing technology is not convenient to adjust and cannot adapt to different shapes of curvatures. The cost is relatively high. For this reason, we propose an adjustable curved carbon fiber molding tooling. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art that it is inconvenient to adjust and cannot adapt to different shapes of curvatures, and to propose an adjustable curved carbon fiber molding tool.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] An adjustable curved carbon fiber molding tool comprises a plurality of bases, each of which is provided with an internal bolt, each of which is rotatably provided with an inner hemispherical pressure block, each of which is provided with a sliding molding body, each of which is provided with a blocking cover, and each of which is provided with a mounting structure.

[0006] Preferably, through holes are provided on the plurality of reinforcing plates, and the plurality of through holes cooperate with the plurality of long bolts.

[0007] Preferably, the mounting mechanism comprises a plurality of mounting plates, and the plurality of bases are respectively mounted on the plurality of mounting plates.

[0008] Preferably, the plurality of sliding forming bodies are each provided with an inner hole, and the plurality of inner holes and the plurality of blocking covers are mutually engaged.

[0009] Preferably, a plurality of long bolts are provided on the plurality of reinforcing plates, and nuts are provided on the plurality of long bolts.

[0010] Preferably, the plurality of adding plates are respectively provided with positioning rods and positioning holes, and the plurality of positioning rods and the plurality of positioning holes cooperate with each other.

[0011] Preferably, a plurality of electric push rods are arranged on the plurality of adding plates, and one end of the plurality of electric push rods is fixedly connected to the plurality of bases.

[0012] Preferably, arc grooves are provided on the plurality of bases, and the plurality of arc grooves are movably connected to the plurality of inner hemispherical pressure blocks.

[0013] In the present invention, the beneficial effects of the adjustable curved carbon fiber forming tooling are as follows: a plurality of pressing block units are arranged through computer simulation to complete the height adjustment and position arrangement of each pressing block unit, so as to achieve the purpose of satisfying the required shape as a whole; because the contact surface between the base of the pressing block unit and the sliding forming body is a spherical surface, the angle of normal phase adaptation after force is applied can be achieved; different height controls and different position arrangements enable the tooling to meet the blank forming requirements of different shapes.

[0014] The present invention can press and form a straight plate into a blank plate with a curved surface of a certain curvature, and can adapt to different shapes and curvatures, facilitate adjustment, and save costs. BRIEF DESCRIPTION OF THE DRAWINGS
