Five-axis additive manufacturing and subtractive manufacturing compound machining device

Abstract

The invention discloses a five-axis additive manufacturing and subtractive manufacturing compound machining device, comprising a double-Z-axis additive manufacturing and subtractive manufacturing mould, support beams, a cross beam and a cradle type workpiece tray; the cross beam is arranged to be linearly fed along a guide rail on the top surface of the support beams along the horizontal Y-axis direction; the double-Z-axis increase and decrease material module is arranged to be linearly fed along the X-axis of the cross beam; the double Z-axis additive manufacturing and subtractive manufacturing mould comprises a moving frame, a print head and a milling head; the print head and the milling head are respectively installed at the two sides of the moving frame, and the print head and the milling head are arranged to slide along guide rails respectively arranged in the Z-axis direction so as to be linearly fed; in a space between the support beams at the two sides of the lower part of thecross beam, the cradle type workpiece tray rotates about the X-axis direction by means of two arms; the cradle-type workpiece tray is arranged to circumferentially rotate along the circumferential direction perpendicular to the plane where a fixed plate is positioned. The five-axis additive manufacturing and subtractive manufacturing compound machining device integrates additive manufacturing andsubtractive manufacturing, thus greatly reducing the component manufacturing cycle, and facilitating the manufacturing of parts with higher precision; furthermore, the device is wide in applicability.

Description

technical field [0001] The invention relates to a manufacturing and processing equipment for high-precision parts, in particular to a processing device for adding and subtracting materials. Background technique [0002] Additive Manufacturing (AM), commonly known as 3D printing, combines computer-aided design, material processing and forming technology, based on digital model files, and uses software and numerical control system to integrate special metal materials, non-metal materials and medical biomaterials , According to extrusion, sintering, melting, photo-curing, spraying and other ways to accumulate layer by layer, the manufacturing technology of manufacturing physical objects. Compared with the traditional processing mode of raw material removal-cutting and assembly, it is a "bottom-up" manufacturing method through material accumulation, starting from scratch. [0003] The difference from additive manufacturing is that traditional machining methods such as cutting a...

Just like two brothers, although each has its own good and bad, but neither can be replaced

Although the traditional manufacturing process is complicated, the operation is cumbersome, and the realization of some processes requires many conditions, it can meet certain high standards in many aspects, and it is far superior to additive manufacturing in terms of mass production. of

In the current 3D printing industry, first of all, materials are a major difficulty, and the requirements for materials are very high; secondly, additive manufacturing is not suitable for mass production, and the current technical level of additive manufacturing cannot meet the technical requirements in many aspects. achieve

[0005] Therefore, it is usually impossible to meet the high-precision requirements through a single manufacturing method

However, if the processing equipment and processing site are frequently replaced, the turnaround time will be increased, and the positioning error of the replacement fixture will affect the processing accuracy.
