Honeycomb core stretching and dipping and curing integrated device and using method thereof

Abstract

The invention provides a honeycomb core stretching and dipping and curing integrated device and a using method thereof. The honeycomb core stretching and dipping and curing integrated device comprisesa stretching frame (1), a transmission unit (2) and a gum dipping (3); the transmission unit (2) comprises a ball screw (21) which is parallel to a rectangular square tube (11) and two guide rails (22) which are symmetrically arranged on the two sides of the ball screw (21); the ball screw (21) and the two guide rails (22) are sleeved with linear motion ball bearings (24), and fixedly provided with movable block (25) by the linear motion ball bearings (24); the two ends of a honeycomb laminated plate are fixed by the movable blocks (25) and one of fixing blocks (12); and the linear motion ball bearings (24) move away from the fixing blocks (12) in the length direction of the ball screw (21) by rotating a hand wheel (23) to stretch the honeycomb laminated plate. According to the invention,the integration of multiple functions of stretching, dipping and curing of a honeycomb core material can be realized, the use is flexible and convenient, and the honeycomb core stretching and dippingand curing integrated device is suitable for efficient preparation of small batch and multi-variety honeycomb materials.

Description

technical field [0001] The invention belongs to the technical field of honeycomb preparation, and relates to an integrated device integrating stretching, impregnation and curing of honeycomb laminated plates and a method of use thereof, in particular to a stretching device capable of resisting high temperatures of 300°C and above for honeycomb preparation. Background technique [0002] The honeycomb sandwich structure is made according to the principle of honeycomb structure in nature, and it is a kind of material with light weight, high strength and high specific stiffness. With the continuous improvement of the flight Mach number of aerospace vehicles, the new generation of weaponry systems has put forward an urgent demand for lightweight and high-temperature resistant honeycombs. The traditional corrugated paper honeycomb, aramid honeycomb aluminum honeycomb, etc. are limited by the performance of the base material and the core strip glue, and the temperature resistance l...

AI Technical Summary

Problems solved by technology

At 300°C, the base material and core strip glue decompose or the performance of the base material is severely attenuated, resulting in a significant decline in the mechanical properties of the honeycomb, which cannot meet the use requirements.

Although laser-welded titanium alloy honeycomb and high-temperature alloy steel honeycomb have excellent temperature resistance and mechanical properties, their disadvantages of large capacity, complicated molding process and high manufacturing cost limit their popularization and application.

[0003] Although the current honeycomb automated production line has high preparation efficiency, but the fixed cost of equipment is high, it is not suitable for the manufacture of small batches of multi-variety honeycomb core materials

In addition, the heating temperature of the drying tunnel of the honeycomb automated production line generally does not exceed 300°C, which is difficult to meet the long-term high-temperature resistant honeycomb preparation requirements of 300°C

However, the traditional manual stretching method is too rough, there are many kinds of stretching tools and different styles, the connection between multiple processes is poor, and the regularity and consistency of the honeycomb produced are poor.
