Double-station metal material adding and milling-grinding composite manufacturing equipment

Abstract

The invention discloses double-station metal material adding and milling-grinding composite manufacturing equipment. The double-station metal material adding and milling-grinding composite manufacturing equipment comprises a material adding station located in inert gas protective atmosphere and a material reducing station located in an air environment, the material adding station is isolated from the material reducing station in a sealed manner, and the material adding station and the material reducing station are located above an X-axis lathe bed; an A / C axis swing and rotation workbench which can move along a slide rail is mounted in the vertical direction of the X-axis lathe bed and can be switched between the material adding station and the material reducing station. The double-station metal material adding and milling-grinding composite manufacturing equipment has the advantages that the material adding station uses multi-axis linkage of an X axis, a Y axis, a Z axis, an A axis and a C axis to perform material adding accumulation, a B-axis index head is used to change the feeding direction of a fusion covering head, and the equipment is applicable to the formation of complex parts with cantilever features or narrow inner spaces; the material reducing station uses multi-axis linkage of an X axis, a V axis, a W axis, an A axis and a C axis to perform material reducing processing, flexible switching between adding and reducing is achieved while adding and reducing environments are not destroyed, and procedure compositing can be achieved favorably.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a double-station metal additive and milling-grinding composite manufacturing equipment. Background technique [0002] Additive manufacturing technology is suitable for forming complex shapes, but the existing metal additive manufacturing process still has the problem that the surface quality and dimensional accuracy are difficult to meet the requirements of parts, and it is often necessary to use subtractive methods for processing to ensure the surface quality and dimensional accuracy of parts. Dimensional accuracy. However, for difficult-to-machine parts with complex profiles, inner holes, inner cavities and other features and high precision requirements, there are often interference problems that the tool cannot reach during cutting, so that the inner cavity profile and narrow outer profile cannot be processed. The realization of processing cannot guarantee ...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned existing technologies all adopt the method of integrating the function of adding materials and reducing materials at the same station. When manufacturing easily oxidized materials such as titanium alloys and high-temperature alloys, it is necessary to protect the entire station with an atmosphere of inert gas. The atmosphere environment will be destroyed when the material is switched, and it takes a long time to re-establish the atmosphere protection environment, so the efficiency is extremely low. This is also the main reason why it is difficult to realize the composite manufacturing of titanium alloy and other parts with the current composite manufacturing equipment.

At the same time, the environment is in a heated state when adding materials, and needs to be cooled when reducing materials. It is not easy to realize temperature control at the same station, which is not conducive to the controllability of parts.

In addition, for powder-feeding laser cladding and subtractive composite, the same station will cause mutual contamination of powder and iron filings, which is not conducive to the recycling of powder materials
