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 metal foil numerical control cutting and gluing direct forming additive manufacturing equipment and method of the present invention, the device includes a conveyor belt, the conveyor belt passes through a laser cutting machine, and a digital programming route is arranged inside, and a computer combines a manipulator to complete the cutting station. The final workpiece is sliced ​​and programmed in advance and then digitally cut to obtain special-shaped metal foil for additive manufacturing slicing. The suction cup completes the separation of waste and metal special-shaped foil, and glues to complete the lamination operation of the final metal structure. Cycle operation until the workpiece blank of the designed shape is obtained, and solidified to realize additive manufacturing. This method takes advantage of the ultra-soft characteristics of the metal foil, and under the cooperation of the mold, the metal structural parts with complex shapes are stacked layer by layer. Compared with traditional additive manufacturing, this method greatly shortens the processing process and greatly reduces costs by using lower-priced metal foils. In addition, all waste materials are recycled during the entire production process, without reaching the melting point temperature and long-term heating and molding, saving energy and reducing pollution.

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,...
