A honeycomb core stretching-impregnation-curing integrated device and its use method

Abstract

The invention provides a honeycomb core stretching-impregnation-curing integrated device and its use method, the device includes a stretching frame (1), a transmission unit (2) and a dipping unit (3), the transmission unit (2) It includes a ball screw (21) parallel to the rectangular square tube (11) and two guide rails (22) symmetrically installed on both sides of the ball screw (21); the ball screw (21) and the two guide rails (22) The upper sleeve is provided with a linear motion ball bearing (24), and a movable block (25) is fixed through the linear motion ball bearing (24), and the movable block (25) and one of the fixed blocks (12) fix the two ends of the honeycomb laminated plate, By turning the handwheel (23), the linear motion ball bearing (24) moves away from the fixed block (12) in the length direction of the ball screw (21), stretching the honeycomb laminated plate. The invention can realize the multifunctional integration of stretching-impregnation-curing of the honeycomb core material, is flexible and convenient to use, and is suitable for the efficient preparation of small batches of multi-variety honeycomb materials.

Description

technical field [0001] The invention belongs to the technical field of honeycomb preparation, and relates to an integrated device for stretching, dipping and curing of a honeycomb laminated plate and a method for using the same, in particular to a stretching device for honeycomb preparation resistant to high temperature of 300°C and above. Background technique [0002] Honeycomb sandwich structure is made according to the principle of honeycomb structure in nature. 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 spacecraft, a new generation of weapon equipment systems has put forward an urgent demand for lightweight and high temperature resistant honeycombs. The traditional corrugated honeycomb, aramid honeycomb aluminum honeycomb, etc. are limited by the performance of the substrate and the core strip adhesive, and the temperature resistance level is below 200 ℃. At 300°C, t...

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.
