Abstract

The invention belongs to the technical field of additive manufacturing post-processing, and in particular relates to an inner cavity vibrating cleaning powder and inner surface finishing equipment for laser selective melting forming hollow lattice wing rudder products. The equipment can effectively solve the problems of manual knocking and cleaning of residual powder in the inner cavity and poor quality of the inner surface of the current laser selective melting and forming airfoil products by using the vibration rotation system, powder cleaning power and recovery system, and inner surface finishing system. Realize the efficient and rapid cleaning of the residual powder in the inner cavity of the airfoil-like hollow lattice complex structure, greatly improve the efficiency of powder cleaning and ensure the cleaning quality of the residual powder in the inner cavity. The invention integrates the electrochemical workstation into the device, which can realize the electrochemical polishing of the inner surface of the airfoil and improve the surface quality of the inner cavity of the entire airfoil.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing post-processing, and in particular relates to a device for vibrating inner cavity powder cleaning and inner surface finishing of laser selective melting forming hollow lattice wing rudder products. Background technique [0002] The laser selective melting forming technology selectively irradiates the pre-spread metal powder by focusing a fine laser light source, and accumulates it into three-dimensional metal parts layer by layer. Compared with the traditional casting and forging technology, the laser selective melting forming technology has many advantages such as the ability to obtain rapidly solidified non-equilibrium structures, fine internal grains, excellent comprehensive mechanical properties, and the ability to form parts with arbitrary structures. Topology optimization design and manufacturing provides new ideas and becomes an important development direction of advanced man...
