Embodiment Construction

[0006] For the convenience of operation, the lower roll of the rolling mill of the present invention remains unchanged, and only many small holes are evenly drilled on the surface of the upper roll, with a diameter of 3 to 8 mm and a depth of 10 to 30 mm, so that the surface of the upper roll is honeycomb-shaped, and then in each small hole Each anchors a hexagonal protruding indenter with a hexagonal cross-section and a hexagonal cone with a taper of about 30%. The shallow-hole blind-hole honeycomb panels for aircraft, roof tiles, and bags can be rolled at one time. The deep-hole blind-hole honeycomb panels for ships and furniture can be equipped with a laser locator so that the honeycomb holes will not be damaged during repeated rolling.

[0007] A layer of aluminum foam core board is sandwiched between two aluminum alloy blind hole honeycomb panels, heated to about 150 degrees Celsius, and then hot rolled into a composite honeycomb panel, because the honeycomb reinforcing ri...

Abstract

The invention relates to a rolled blind hole cellular board and a method for manufacturing a composite cellular board with the same. The surface of one roller of a rolling machine is full of hexagonal nail-shaped protruding pressing heads, so that one surface of a rolled metal plate is flat and straight, and the other surface of the rolled metal plate is provided with blind hole cellular reinforcement ribs. Production is simple, the yield is large, strength is high, and the defect that a panel and a core plate of a common glued cellular board are prone to separating is avoided. Metal blind hole cellular boards, such as cold-rolled aluminum alloy blind hole cellular boards for advertisement boards, automobile cases and planes, and steel blind hole cellular boards for roofs, security doors and ships can be rolled, and non-metal blind hole cellular boards, such as wood blind hole cellular boards for packages and furniture, and (rigid foam) plastic blind hole cellular boards for luggage and household appliances, especially composite cellular boards composed of blind hole cellular boards and rigid form plates can be rolled. The rolled blind hole cellular board can serve as novel building and decoration materials, traffic tool high-strength structural parts and the like.

Description

technical field [0001] The invention relates to a method for manufacturing a honeycomb panel, in particular to a method for rolling a honeycomb panel with blind holes and using it as a composite honeycomb panel. Background technique [0002] At present, the known manufacturing method of honeycomb panels is to use adhesives to bond the panels and honeycomb core panels together. split and reduce the working life. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the present invention uses a rolling mill to roll blind-hole honeycomb panels, and uses the blind-hole honeycomb panels to make composite honeycomb panels. [0004] The technical solution adopted in the present invention is: the surface of one of the rolls is covered with hexagonal columnar protruding indenters, and each hexagonal columnar protruding indenter has a certain taper to roll the strip-shaped plate into a blind Hole honeycomb panel, its further improvement is tha...
