Method, equipment and system for manufacturing metal product and control method of equipment

Abstract

The invention relates to a method, equipment and system for manufacturing a metal product and a control method of the equipment. The method comprises the following steps: firstly using a 3D printing method to print a model of the metal product to be manufactured with a fusible material to form a fusible material male die, meanwhile conducting the 3D printing on the periphery of the fusible material male die to form a fusible material female die, injecting high-temperature-resistant material slurry into a cavity defined between the fusible material male die and the fusible material female die, drying and molding the high-temperature-resistant material slurry, and meanwhile after the fusible material is molten, forming a high-temperature-resistant material female die, injecting molten metal in the high-temperature-resistant material female die, and cooling the molten metal to form the model of the metal product. With adoption of the equipment and the method disclosed by the invention, the production automation for the metal product with any shape is achieved, the production precision is high, and the costs for production and the equipment are low.

Description

[0001] technical field [0002] The invention belongs to the field of manufacturing technology, and in particular relates to a method for manufacturing metal products, used equipment and systems and a control method thereof. Background technique [0003] In the field of industrial manufacturing, 3D laser printing technology is now mostly used. Using 3D laser to print metal, powdered metal is mostly used, and the object is constructed by layer-by-layer printing through high-power laser / electron beam sintering and accumulation. This method has the following defects: [0004] 1) Due to the layer-by-layer printing method, the printing speed is slow; [0005] 2) There are microscopic pores in the metal powder during the sintering process, the filling rate is low, and the printed product has low density and poor strength, which damages the mechanical properties of the metal product; [0006] 3) The metal is easily oxidized during the sintering process; [0007] 4) The stru...
