Technical Field

The invention relates to the technical field of honeycomb material processing, in particular to a method for manufacturing a honeycomb strip.

Background

The honeycomb core is used as a material of an interlayer in the honeycomb plate, mainly bears shear stress in the interlayer structure, so that the interlayer structure has high bending rigidity, and the honeycomb core is a light material, so that the honeycomb plate is light in weight and excellent in mechanical property, and is widely applied to the fields of aviation, shipbuilding, buildings, trains and the like.

In the manufacturing process of the honeycomb core, a plurality of glue layers are coated on the surface of an aluminum foil at intervals through an automatic glue coating machine, the aluminum foil coated with the glue layers is stacked one by one, the aluminum foil is taken down when the number of stacked layers reaches the required number, and is cut into honeycomb strips for standby after hot-pressing and curing, and when the honeycomb core needs to be used, the honeycomb core is drawn into the honeycomb core through a honeycomb core drawing machine.

Currently, the use of honeycomb strips has the following problems:

firstly, it is extravagant more: in the stretching process of the honeycomb strips, a plurality of honeycomb holes are firstly stretched on two sides of the honeycomb strips through tools, two groups of hooks of the honeycomb core stretcher are respectively hung in the honeycomb holes stretched on two sides, and two groups of hooks of the honeycomb core stretcher are operated to move in the opposite direction, so that the honeycomb strips are stretched to form honeycomb cores. In the stretching process, the pulling force of the honeycomb core stretcher can cause honeycomb holes hung by hooks and peripheral honeycomb holes of the honeycomb holes to deform, so that the two sides of the formed honeycomb core can deform in multiple positions, the deformed positions on the two sides of the formed honeycomb core need to be cut for use, the waste of materials is caused, the width of the honeycomb core manufactured at present is limited, waste materials need to be cut for each honeycomb core, a large number of honeycomb cores are used by a honeycomb plate factory every day, the amount of the generated waste materials is very large, and the waste materials can only be treated as waste articles.

Secondly, the transportation is inconvenient: the strip-shaped honeycomb strips are soft and high in density, so that the honeycomb strips are inconvenient to directly carry and easy to collide and damage in the transportation process if careless; and some honeycomb strips are longer, for example, the honeycomb plate for manufacturing the seamless wall has a larger area, and a honeycomb core with a larger area is correspondingly needed, so that longer honeycomb strips are needed, and the longer the honeycomb strips are, the more difficult the honeycomb strips are to transport.
