Edge folding device and method for machining composite honeycomb type aluminum gusset plate

Abstract

The invention discloses an edge folding device and method for composite honeycomb type aluminum gusset plate machining in the technical field of honeycomb type aluminum gusset plate machining, and the edge folding device comprises a machine barrel, a groove carving mechanism is arranged in the machine barrel, the groove carving mechanism comprises a spline sleeve rod rotationally connected to the interior of the machine barrel in a limited mode, and the lower end of a spline shaft is fixedly connected with a cutting head; a cutting head is arranged on the machine barrel, a chip inlet is formed between cutting edges of the cutting head, the cutting head is communicated with a spline shaft, the spline shaft is communicated with a spline sleeve rod, first gears are arranged on an output shaft of the second motor and the outer wall of the spline sleeve rod, and the two first gears are meshed with each other; the upper end of the filter box communicates with and is fixedly connected with a negative pressure cylinder, the upper end of the spline sleeve rod extends into the filter box and is provided with a rotating disc, and a negative pressure device capable of extracting air flow in the negative pressure cylinder outwards is arranged in the negative pressure cylinder. During cutting, the bottom aluminum alloy layer cannot be cut, and meanwhile flying chips are not likely to be caused.

Description

technical field [0001] The invention relates to the technical field of processing a honeycomb-type aluminum gusset, in particular to a hemming device and method for processing a composite honeycomb-type aluminum gusset. Background technique [0002] Honeycomb aluminum panel is a metal composite panel product series developed in combination with the composite honeycomb panel technology of the aviation industry. The product adopts a "honeycomb sandwich" structure, that is, a composite plate made of high-strength alloy aluminum plate coated with a decorative coating with excellent weather resistance as the surface, bottom plate and aluminum honeycomb core through high temperature and high pressure. This product series has the advantages of excellent material selection, advanced technology and reasonable structure. It not only has excellent performance in large scale and flatness, but also has many choices in terms of shape, surface treatment, color and installation system. In ...
