A preparation device for folding honeycomb precursor and its use method

Abstract

The invention relates to a manufacturing device and a manufacturing method for a folding honeycomb precursor. The device comprises a rack, an upper roller press cutter wheel, a lower roller press cutter wheel, a feeding mechanism and a control mechanism, wherein the upper roller press cutter wheel and the lower roller press cuter wheel are fixed on the rack, the feeding mechanism and the control mechanism are arranged on one side of the rack, the upper roller press wheel and the lower roller press cutter wheel are oppositely arranged, the feeding mechanism is used for feeding a plastic sheet between the upper roller press cutter wheel and the lower roller press cutter wheel, annular cutter structures are arranged on the upper roller press cutter wheel and the lower roller press cutter wheel in the circumferential direction of the upper roller press cutter wheel and the lower roller press cutter wheel, horizontal cutter structures are arranged on the upper roller press cutter wheel andthe lower roller press cutter wheel in the length direction of the upper roller press cutter wheel and the lower roller press cutter wheel, the upper roller press cutter wheel and the lower roller press cutter wheel rotate under the control of the control mechanism, and the plastic sheet is machined into the folded honeycomb precursor with a target shape through the annular cutter structures and the horizontal cutter structures. According to the manufacturing device and the manufacturing method, a honeycomb core material with reinforced fibers can be rapidly and continuously produced, the performance range of the plastic honeycomb core is widened, the production cost is reduced, the production efficiency is improved, and the production requirements of high efficiency and low cost are met.

Description

technical field [0001] The invention relates to the technical field of composite material manufacturing, in particular to a manufacturing device and method of a folded honeycomb precursor. Background technique [0002] Honeycomb material is the simplest porous material, which has excellent energy absorption, heat insulation, structure, buoyancy, etc., and has the characteristics of small weight and high rigidity, so it is widely used in packaging, military, aviation, construction, furniture, transportation It has a wide range of applications in tool manufacturing and other fields. It can be used as cushioning material on product packaging, and made into honeycomb liner, honeycomb box and honeycomb tray, etc. In aviation, honeycomb materials can be used to make aircraft floors, wings, fairings, spoilers, rudders, side walls, and can also be used to make the base of spacecraft landing modules, spaceship landing gear, and communication satellites. Communication deck, service ...

Problems solved by technology

[0004] The honeycomb core material is an important part of the honeycomb composite material. In the prior art, the plastic honeycomb core material is mostly a polypropylene round tube honeycomb core material (such as a PP thermoplastic round tube honeycomb core material disclosed by CN204554338U), although the polypropylene Round tube honeycomb core materials are easy to manufacture, but their mechanical strength is limited by the properties of polypropylene, while high-strength fiber composite materials such as folded honeycomb precursors are folded into honeycomb cores. The material is 30% glass fiber reinforced polypropylene, and the wall thickness Due to the high melt viscosity, the traditional production process of polypropylene circular tube honeycomb core material cannot be produced at all.
