Problems solved by technology

[0004] However, most of the existing laser selective forming equipment is designed with a fixed powder cylinder size. During the forming process, regardless of the size of the part, the entire forming powder cylinder needs to be filled with metal powder, and the powder waste is serious when forming small components.
In addition, the existing laser forming equipment does not co

Embodiment Construction

[0039] Below in conjunction with accompanying drawing, the present invention will be further described:

[0040] like figure 1 As shown, the present invention is a double-piston metal laser selective melting and forming equipment. The main body 1 and the auxiliary body 4 are fixed inside the casing 3 , and the main body 1 is on the left side of the auxiliary body 4 . The casing 3 of the main body 1 is provided with an observation window 2, and the observation window 2 is made of light green glass material, which can prevent 1030-1080nm laser radiation from causing harm to the human body. The casing 3 of the auxiliary body 4 is provided with an operation panel 5, the operation panel is a touch screen, and a keyboard is arranged under it for operating the forming equipment.

[0041] like figure 2 As shown, the frame 10 is formed by splicing aluminum alloy profiles or welding rectangular steel. A base plate 7 is provided at the bottom of the frame 10, and feet are installed on...

Abstract

The invention discloses double-piston metal laser selective melting molding equipment. The double-piston metal laser selective melting molding equipment comprises a main machine body, an auxiliary machine body, a powder cylinder, a scraper motion component and a light path system. The equipment can work in a single-piston state and a double-piston state. Integrated double-piston design is adopted, the equipment can work independently in the single-piston state and the double-piston state, a small piston can be replaced and dismounted to achieve laser molding of metal components of different sizes, and powder is saved; meanwhile, omnibearing heating can be carried out on the powder cylinder, and the powder is controllably preheated, so that the powder is evenly heated, temperature gradient is improved, and component deformation and cracking are relieved.

Description

Technical field: [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a dual-piston metal laser selective melting forming equipment. Background technique: [0002] Additive manufacturing technology (also known as "3D printing") is a high-end digital rapid manufacturing technology that has developed rapidly in recent years. It is suitable for the near-net shape of complex components. The formed parts manufactured by additive manufacturing technology have excellent mechanical properties. , suitable for rapid prototyping of various materials, and the material utilization rate is high. Selective Laser Melting (SLM) technology is a typical representative of additive manufacturing. It transforms the traditional three-dimensional manufacturing process into a planar manufacturing-cumulative superposition process, and realizes the manufacture of three-dimensional complex precision parts through layer-by-layer melting of powder. ...
