Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0048] In the prior art, there are three mainstream powder bed electron beam additive manufacturing equipment. The first type is the powder feeding structure of single powder cylinder. In this structure, only one powder cylinder is located on the left (or right side), and the forming cylinder is located on the right (or left side). Since there is only one powder cylinder, and the powder cylinder can only Install a single material powder, otherwise it will caus...

Abstract

The invention discloses powder bed electron beam additive manufacturing equipment and a method, and belongs to the field of powder bed additive manufacturing equipment. It solves the problem that the existing powder bed electron beam additive manufacturing equipment can only print a single material, but cannot print two materials. The equipment comprises: a first powder spreading unit located on a first side of the forming chamber for setting the first powder; a second powder spreading unit located on the second side of the forming chamber for setting the second powder; a forming cylinder , which is located in the middle of the forming chamber, and its upper surface is in contact with the first powder spreading unit and the second powder spreading unit respectively; the forming cylinder, which is located in the forming chamber, is used to drive the forming cylinder through the bearing arranged on the forming cylinder. The third powder spreading platform on the upper surface of the cylinder rotates to scrape the first powder and the second powder into the forming cylinder in turn, wherein the upper surface of the third powder spreading platform is connected with the first powder spreading unit and the second powder spreading unit respectively. The powder unit is in contact.

Description

technical field [0001] The invention relates to the field of powder bed additive manufacturing equipment, and more specifically relates to a powder bed electron beam additive manufacturing equipment and method. Background technique [0002] Powder bed electron beam metal additive manufacturing technology is one of the mainstream technologies of metal additive manufacturing. The powder bed electron beam additive manufacturing technology is similar to the laser printing powder making process. First, a layer of metal powder is laid, and then the electron beam scans and prints. The powder bed electron beam additive manufacturing technology is different from the laser printing powder making process. The bed electron beam can preheat the powder bed, so there is an intermediate preheating process in the powder bed electron beam additive manufacturing technology; moreover, compared with the laser printing powder, the powder bed electron beam additive manufacturing technology also ha...
