Workpiece hammering reinforcing device for metal additive manufacturing process

Abstract

The invention discloses a workpiece hammering reinforcing device for a metal additive manufacturing process, and relates to the technical field of metals. The workpiece hammering reinforcing device for the metal additive manufacturing process comprises a base, pushing rods and a guide rod, wherein a propping rod is mounted in the middle part of the base, and a limiting chute is formed in the upperpart of the propping rod; a flat plate is mounted at the upper part of the limiting chute; supporting rods are mounted at the left side and the right side of the flat plate, and adjusting screws arearranged in the supporting rods; and servo motors are mounted at the front ends of the pushing rods, and the pushing rods are positioned at the upper parts of the supporting rods. According to the workpiece hammering reinforcing device for the metal additive manufacturing process, a dust cover is capable of preventing outside dust from entering the guide rod; an oil ring is capable of preventing lubricating oil from leaking; and an oil-immersed sponge is capable of effectively lubricating a piston rod to reduce the mechanical abrasion between the piston rod and the guide rod as well as effectively reducing the impact force between the piston rod and the guide rod.

Description

technical field [0001] The invention relates to the technical field of metal additive manufacturing equipment, in particular to a hammer strengthening device for workpieces in the metal additive manufacturing process. Background technique [0002] In the additive manufacturing process, computer design software is used to make a 3D model of the workpiece, and then the 3D model is layered and sliced ​​in the computer to discretize the 3D model into a series of 2D layers, and path planning and parameter optimization are performed on each layer, and then The energy source is used to scan layer by layer and add material layer by layer to convert the 3D model into a solid workpiece. However, in the existing metal additive manufacturing process, the molten metal melts and solidifies rapidly under a large temperature gradient, which may be Various special internal metallurgical defects occur in local areas such as between layers and between different laps in the workpiece.
