Selective laser cladding and grinding in-situ composite manufacturing device

Abstract

The invention belongs to the field of additional material and subtractive material composite manufacturing, and concretely relates to a selective laser cladding and grinding in-situ composite manufacturing device. The device is formed by a laser cladding head, a laser cladding head Z-direction moving mechanism, a fine grinding wheel, a rotation B shaft, a grinding head Z-direction moving mechanism, a lathe bed, a forming parts, a first powder supply tank, a powder recovery tank, a powder dust collector, a base plate, a lifting table, a Y-direction moving platform, an X-direction moving platform, a machine tool base, a forming chamber, a protection air source, a powder recycle bin, a powder paving wheel, a second powder supply tank, a control cabinet, a machine tool protection cover and thelike. Two processing methods, i.e. additive material manufacturing and subtractive material manufacturing are integrated on one device, and are used for in-situ composite manufacturing, so that not only can the defects of dimensional accuracy and surface quality in a single additive material manufacturing technology be overcome, but also the restriction of grinding process in parts complexity canbe overcome, and high-efficient precision laser additive material manufacturing of various complex metal parts is hopefully realized.

Description

technical field [0001] The invention belongs to the field of composite manufacturing of additive and subtractive materials, and in particular relates to an in-situ composite manufacturing device of selective laser cladding and grinding. Background technique [0002] (1) Selective laser cladding (SLM) belongs to additive manufacturing. Compared with traditional material removal and forced deformation processing methods, it can manufacture metal parts with arbitrary complex structures and close to density. It is suitable for manufacturing in-band runners, Parts with complex twisted surfaces and special-shaped closed cavities such as inner cavities, porous parts, and thin-walled parts have good application prospects. The metal parts after laser cladding have excessive surface roughness and low forming accuracy. The inner cavity, special-shaped holes, and complex curved surfaces of the formed parts are prone to processing dead corners and blind areas, making it impossible to car...

AI Technical Summary

Problems solved by technology

The metal parts after laser cladding have excessive surface roughness and low forming accuracy. The inner cavity, special-shaped holes, and complex curved surfaces of the formed parts are prone to processing dead corners and blind areas, making it impossible to carry out subsequent processing or treatment, which not only affects the metal parts. Forming accuracy and performance, but also limit the further popularization and application of selective laser cladding method
