General application, but since the characteristics of technology itself limits its application in metal parts Rapid Prototyping Manufacturing field, especially
It is utilizing existing high energy beam（Laser, electricity in beam and wait from）When increases material manufacturing technology manufactures large complicated hardware
Encounter bottleneck.Because the increasing material manufacturing process of metal experienced complicated physics and control golden process, material that when part forming is undergone
Fusing, solidification and cooling all carry out under conditions of being exceedingly fast, and inevitably cause to be between molten bath and matrix prodigious
Temperature gradient will produce thermal stress and residual stress in this way, and being also easy to produce micro-crack reduces the toughness of material.Meanwhile material internal
Metal structure be as cast condition, show dendroid.In addition, due to the influence of a variety of forming technology factors during increasing material manufacturing,
Crackle is easily formed in metal deposition layer, stomata, is mingled with, the defects of Coating combination is bad, spherical effect, microcosmic group of material internal
Knitting defect leads to the mechanical property of increasing material manufacturing metal parts（Such as toughness, intensity and fatigue behaviour）Deterioration, this is to influence
Increases material manufacturing technology manufactures the main technical bottleneck of application in metal parts, particularly large complicated metal component.
Therefore, how to improve material internal microstructure, alkali lacks material internal defect, improves the mechanical property of metal parts
Can, reducing and eliminate increasing material manufacturing metal parts internal residual stress prevents from deforming and cracking, realizes band large-scale metal component control
Shape control increasing material manufacturing is one important research direction of current metal material increasing field.
There are post-processing technology, ultrasound dry currently, solving increasing material manufacturing microstructure and mechanical property main method and technology
Disturb, ultrasonic impact and rolling rolling technique.By to current existing several improvement increasing material manufacturing microstructures and raising metal
The method of parts mechanical property is analyzed it can be found that these methods and techniques, can improve metal increasing to a certain extent
Material manufacture material interior microscopic tissue and the mechanical property for improving metal parts, but each increasing material manufacturing householder method is all deposited
In certain limitation, can only use under certain conditions.
Invention content
Device being forged for metal increasing material manufacturing the purpose of the present invention is to provide a kind of, metal can be solved and increase material system
It is coarse and uneven to make cracking, material internal defect and material internal microstructure caused by material prepared internal residual stress
Caused by even the problems such as parts poor mechanical property.
To realize the above-mentioned technical purpose, the technical solution adopted by the present invention is：A kind of forging for metal increasing material manufacturing
Device, including print head, guide holder, guide rod, forging hammer, guide bearing and vibrating seat, the guide holder are held tightly on the print head, are led
It is symmetrically arranged on seat in two guide bearings and each guide bearing and is provided with a guide rod, being internally provided with for guide rod is led
Hole, the lower end of guide rod is fixed on forging hammer, upper end is fixed on vibrating seat, and water supply connector and water outlet connector are mounted on vibrating seat
And be connected to guide hole, the first vibrating motor and the second vibrating motor are mounted on vibrating seat and are located at the both sides of print head,
First vibrating motor and the second vibrating motor drive forging hammer up-down vibration to strike workpiece when working.
Further, the forging hammer is circular ring type and is internally provided with annular coolant flow channel, and the guide hole of guide rod is flowed with cooling
Road is connected to.
The beneficial effects of the invention are as follows：It is a kind of to forge device for metal increasing material manufacturing, by first vibrating motor and
Second vibrating motor drives forging hammer up-down vibration to forge workpiece when metal successively prints, and it is peculiar can to eliminate increasing material manufacturing drip molding
Rule dendrite tissue, so that its each layer microstructure is transformed into as-forged microstructure by as cast condition, substantially crystal grain thinning
With raising mechanical property.
