Description

【Technical field】 [0001] The invention relates to a forming device and method for a corrugated foil material, in particular to a forming device and method for a corrugated foil material with a metal honeycomb core. 【Background technique】 [0002] One of the key technologies for manufacturing high-density metal honeycomb cores by forming method lies in the forming quality of the semi-regular hexagonal corrugated foil, which directly affects the quality of the formed metal honeycomb. If the semi-regular hexagonal corrugated foil The forming quality of corrugated foil is so poor that it is even difficult to form high-density metal honeycomb. On the basis of the traditional forming method for manufacturing semi-regular hexagonal corrugated foils, this invention proposes a set of forming devices that integrate the forming and shaping of semi-regular hexagonal corrugated foils, which effectively solves the problem of low forming precision and forming quality in traditional forming...

Problems solved by technology

[0005] For the first type of semi-regular hexagonal corrugated foil forming (rolling forming), since the tooth shape of the forming roller is a non-involute tooth shape, the transmission is discontinuous and unstable during the meshing of the roller teeth, and there is a large local presence in the movement. The gap between the upper bottom and the hypotenuse of the formed semi-regular hexagonal foil lattice is smaller than the angle between the bottom and the hypotenuse, and there is obvious arc bending, which is not conducive to the subsequent manufacturing process of the metal honeycomb core. Complete, and there are obvious extrusion marks near the corners of each tooth top and tooth root, which reduces the quality of the semi-regular hexagonal corrugated foil, thus directly affecting the bearing strength of the metal honeycomb core

For the second type of forming device (stamping forming), due to the small and dense lattice unit of the semi-regular hexagonal corrugated foil, the stamping process is complicated, the precision of the stamping mechanism is high, the stamping efficiency is low, and it is difficult to realize full automation. The thickness of some parts of the semi-regular hexagonal corrugated foil has obvious thinning phenomenon, which reduces the bearing strength of the metal honeycomb core
