Problems solved by technology

The first five methods are traditional methods for forming metal structural parts, and their disadvantage is that they cannot form complex shapes; while 3D printing can produce metal parts with complex shapes, but because of the high temperature melting process, pores, thermal cracks and balls will also occur. Defects such as
The printing time is very long and the efficiency is very low, for example, it takes several hours for a mug
Most metal materials have to consider oxidation and other issues, and need to be printed in a vacuum, which limits the size of the workpiece

Abstract

The invention discloses metal foil numerical control cutting and gluing direct forming additive manufacturing equipment and method. The equipment comprises a conveying belt, the conveying belt passesthrough a laser cutting machine, a digital programming route is arranged in the laser cutting machine, and a computer is combined with manipulators to complete a cutting station. A final workpiece issliced, programmed and digitally cut in advance, a special-shaped metal foil for additive manufacturing slicing is obtained, separation of waste and the metal special-shaped foil is completed throughsuction cups, and finally stacking operation of metal structural part is completed through gluing. Circular operation is carried out until a workpiece blank with a designed shape is obtained, and additive manufacturing is realized through curing. According to the method, the ultra-soft characteristic of the metal foil is utilized, and the metal structural part with the complex shape is stacked through layer-by-layer gluing under the cooperation of a mold. Compared with traditional additive manufacturing, the method has the advantages that the machining process is greatly shortened, and the cost is greatly reduced by using the metal foil with lower price. All waste materials are recycled in the whole manufacturing process, melting point temperature reaching and long-time heating forming arenot needed, energy is saved, and meanwhile pollution is reduced.

Description

Technical field: [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a metal foil numerical control cutting and gluing direct molding additive manufacturing equipment and method. Background technique: [0002] Metal foil, which has a strong deformation ability, is usually manufactured by hammer forging or rolling, and most of them are made of materials with good ductility, such as aluminum, copper, tin and gold. It is mostly used in daily life, but if it is hypothermia caused by heat radiation, metal foil can also be used to reduce heat radiation to improve symptoms. Due to its limited post-forming method, the application of metal foil in different fields is limited, such as "hand-sheared steel" made by asynchronous rolling, and its thickness can reach 20 microns. [0003] At present, the forming methods of metal structural parts are generally casting, forging, rolling, extrusion, drawing, and 3D printing. Among them,...
