Problems solved by technology

In the prior art, the superimposed forming of metal sheets manufactured in layers is mainly through laser cutting, arc welding or adhesive bonding of metal sheets to form metal parts. Arc welding consumes a lot of power, and the high temperature of the arc generated during welding makes the metal sheet Melting deformation reduces the processing accuracy of parts, and for metals with high electrical or thermal conductivity such as gold, silver, copper, aluminum, etc., it is difficult to form high temperature due to high electrical conductivity, or because of high thermal conductivity, the formed High-temperature heat is easily guided away, so it is not easy to melt the metal, and it is not easy to weld successfully; the disadvantage of bonding metal sheets with adhesives is that the formed metal parts have low strength, and cracks are prone to occur between the two layers of metal sheets, thus Affect the overall performance of metal parts, it is difficult to meet the actual technical requirements

Abstract

The invention relates to a laminated method for producing metal element, which comprises: building model, dispersing the model, processing layer; based on the data document, using material transmitter to transmit the laminated material; using ultra-sonic welding technique to weld nearby two layers; based on the laminated information, removing the layer surface of welded material, to realize the horizontal and vertical motions; processing the next layer. The inventive ultra-sonic welding has less power consumption, small deformation of welding element, and high strength of welding point. Therefore, the product has high accuracy and lower cost.

Description

technical field [0001] The invention relates to a layered manufacturing method in the field of mechanical processing, in particular to a layered manufacturing method of metal parts. Background technique [0002] With the development and progress of science and technology, more and more rapid manufacturing technology is used in the field of parts manufacturing. Rapid metal product and mold manufacturing technology based on rapid prototyping can be divided into direct rapid manufacturing technology and indirect rapid manufacturing technology, which are classified as figure 1 shown. Indirect manufacturing technologies include precision casting forming, electroforming forming, metal deposition forming and powder metallurgy forming. Due to the need for process conversion, the indirect manufacturing technology has a long cycle and loss of precision, and it is difficult to manufacture molds with high precision and good surface quality. . Direct manufacturing techniques include s...
