Abstract

The invention discloses a substrate-formed part preheating device and method of additive and subtractive manufacturing equipment. According to the device, a far-infrared heating technology is used, non-contact preheating is performed on a substrate and a formed part through a plate-shaped far-infrared heater and an annular far-infrared heater, the plate-shaped far-infrared heater is used for global preheating, the annular far-infrared heater is used for local preheating, global preheating can conduct auxiliary heating on local preheating of the formed part, the plate-shaped far-infrared heaterand the annular far-infrared heater operate cooperatively, local preheating time is shortened, and additive efficiency is improved. Compared with induction heating, furnace heating and other technologies, the device has the advantages that the far-infrared heating technology is safe, efficient and low in cost, and the purposes of shortening the manufacturing period of large and medium structuralparts, reducing the labor cost and increasing the economic benefits can be achieved.

Description

technical field [0001] The invention belongs to the field of laser / arc fuse additive manufacturing (3D printing) of large and medium-sized metal structures, and specifically relates to a substrate-formed part preheating device and method for additive and subtractive material manufacturing equipment. Background technique [0002] In traditional mechanical manufacturing, structural parts are generally processed and formed by subtractive / equal material manufacturing, but for thin-walled parts and more complex structural parts, the traditional processing method is cumbersome and the processing cost is high, especially in aerospace and other fields , Relying on subtractive / equal material manufacturing to process large and medium-sized structural parts has the disadvantages of long cycle, high cost, and low yield. With the rapid development of additive manufacturing technology, the manufacturing problems of large and medium-sized structural parts in aerospace and other fields have...
